About the NCCN Guidelines for Patients™The National Comprehensive Cancer Network® (NCCN®) aims to provide people with cancer and the general publicstate-of-the-art cancer treatment information in easy-to-understand language. The NCCN Guidelines for Patients™, based onthe NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines™), are meant to help you when you talk with yourdoctor about treatment options that are best for you. These guidelines do not replace the expertise and clinical judgment of

your doctor.

About the NCCN Guidelines™The NCCN Guidelines are the most comprehensive and most frequently updated clinical practice guidelines available inany area of medicine. These guidelines provide information that many doctors follow to make sure their decisions for people

with cancer are well informed. The NCCN Guidelines are developed by 43 different NCCN Guidelines Panels composedof nearly 900 world-leading experts from each of the NCCN Member Institutions. Cancer is treated by teams ofdoctors and other health professionals who work together to diagnose and treat cancer. NCCN Guidelines Panels aremultidisciplinary, which means they include experts in different elds reecting the way cancer is treated. These eldsinclude medical oncology, surgical oncology, radiation oncology, pathology, radiology, nursing, and social work.Recommendations in the NCCN Guidelines are based on evaluation of evidence from clinical trials that are publishedin the medical literature. Most of the panel members who develop the NCCN Guidelines perform both clinical researchand treat people with cancer. The members of each NCCN Guideline Panel specialize in the specic tumors and diseasesdiscussed in that NCCN Guideline. Some NCCN Guidelines Panels also have patient advocates to bring the patient’sperspective to the panel discussions. NCCN Guidelines Panel Members volunteer more than 15,000 hours each year torevising and updating the NCCN Guidelines to reect new data and clinical information.

The NCCN Guidelines are used by doctors in academic centers and community practices to inform their decisionswhen diagnosing and treating people with cancer. The NCCN Guidelines encompass 97 percent of the tumors encoun-tered in oncology practices, and these guidelines are continually updated as new information becomes available. With theNCCN Guidelines, doctors and patients have access to the same treatment regimens used by NCCN Guidelines PanelMembers when they treat their patients. The decisions of the expert panel are based on scientic data coordinated withexpert judgment. Community physicians may or may not perform research, but by using the NCCN Guidelines, they haveinformation about the latest evidence from clinical trials and insights to the expertise found at leading cancer centers.

By showing the standard of care, guidelines can reduce variation in how patients are treated and help make sure everyonegets the best care for them. However, no one treatment is right for everyone. Clinical research shows that some treatmentsare better for a particular disease than others. Similarly, studies have demonstrated that different patients with the samecancer may need different treatments. In many cases, patient preference is important especially when selecting amongseveral effective treatments each with different side effects. Recommendations included in the NCCN Guidelines are thosethat NCCN doctors feel are most useful based on the evidence published in medical journals and their own experiencetreating patients. Therefore, even if a treatment is part of the NCCN Guidelines, it may not be the right treatment for allpeople with cancer or all people with that particular cancer. This is because each patient has a specic medical history andindividual circumstances.

On the other hand, not including a particular treatment in the NCCN Guidelines only means that there is not strong enoughevidence at this time to support using it as part of standard practice. In some cases, there may be ongoing clinical trials todetermine whether the treatment is effective. Many new treatments are available because patients have participated in clinical trials. Additionally, new treatments thatare not yet part of standard practice may only be available in clinical trials. You can discuss whether a clinical trial mightbe right for you with your doctor.

The NCCN Guidelines for Patients™ translate the information that doctors use to help you and your family understand your treatment options. They empower you to discuss treatment choices with your health care team and make cancer caredecisions that are right for you. For the most up-to-date versions of the NCCN Guidelines for Patients™, visit NCCN.com.

A diverse group of experts from NCCN Member Institutions developed the NCCN Guidelines for Non-Small Cell LungCancer. Listed on page 6 are the NCCN Guidelines Panel Members whose recommendations for treatment are featured in

these NCCN Guidelines for Patients™.

IntroductionThese NCCN Guidelines for PatientsTM: Non-Small Cell Lung Cancer are designed as a resource to assist patients with cancer whendiscussing treatment options with their doctors. These guidelines do not replace the expertise and clinical judgment of the doctor.

There are several different subtypes of cancer that arise in the lung, which are categorized according to how the tumor cells appearunder a microscope. These guidelines specically address the non-small cell lung cancer subtype. It is also important to understandthat cancers that start in other parts of the body, for example, the breast or intestines, can spread to the lung. While some peoplemay still refer to this as “lung cancer,” it is treated differently than cancers that arise in the lung. Therefore, treatment of cancer thatspreads to the lung is included in the individual NCCN Guidelines for Patients™ that corresponds to where the tumor rst started(e.g., breast cancer).

The NCCN Guidelines for Patients™: Non-Small Cell Lung Cancer are designed to make cancer treatment more understandable.These guidelines apply to most but not all people with non-small cell lung cancer. Their relevance to you and your treatment willdepend on your general health and personal circumstances. The guidelines include several important parts:

• An overview of important questions and issues to discuss with your doctor.• Staging tables that drive the decisions about the best treatments. Your doctor can tell you which stage applies to your cancer.

• The pathways which outline the step-by-step treatment decisions from diagnosis through all phases of treatment and survivorship.Once you know the stage of your cancer, simply follow the arrows corresponding to that stage to view the treatment recommenda-tions as set forth by the NCCN Guidelines Panel for Non-Small Cell Lung Cancer. These pathways are simplied versions of thepathways that doctors use in thinking about how to treat non-small cell lung cancer; however the content is still quite technical.

• Background information is provided in the Discussion section to help you understand this complicated information aboutnon-small cell lung cancer. It includes the tests used in your medical evaluation, factors that lead doctors to recommend onetreatment plan over others for a particular patients, description of the treatments themselves and how combinations of treatmentsare used together to provide the best possible outcomes, and the types of follow up needed after treatment is completed.

• A discussion of each of the pathways is provided, and

• Inevitably, you will encounter unfamiliar words and concepts, either in these guidelines or when talking with your doctor, so aglossary of cancer terms is included. These terms are shown in italics on the rst mention in text.

These guidelines are complicated because non-small cell lung cancer is a complex disease. Many users will nd that it is convenientto move from one part of the guidelines to another and back again rather than reading from beginning to end. The table of contentscan help you navigate from one area to another easily.

Making Decisions about Lung Cancer TreatmentA diagnosis of lung cancer is overwhelming for both patients and their families. A variety of tests will be recommended, followed by a discussionof treatment options, all of which will certainly lead to questions that patients will want to ask their cancer care team. However, it can be hard to

know where to start to ask questions, and some patients and families may feel intimidated when talking to physicians. Therefore, it can be helpfulto consider some general issues as you read through th is guideline to help create a question list. Below are common issues associated withtreatment of non-small cell lung cancer.• Make sure you know the type of lung cancer you have, as this guideline only discusses non-small cell lung cancer.• When making decisions about treatment, it is helpful to ask about the bene ts, risks, and side effects of each treatment and how these can

be managed.• You may want to consider getting a second opinion from another lung cancer specialist before deciding on treatment.• Ask the doctor about the best way to prepare for treatment and how to stay healthy while receiving it in order to speed recovery. - Ask about available support services, such as specially trained social workers and psychologists who understand the

special needs of patients with cancer and their families. - Cancer support groups are very helpful and groups are available for both patients and loved ones; you may want to

consider joining one. - Ask how you can help yourself remain t and healthy: diet, exercise, acupuncture, vitamins, imagery, massage, etc.• Feel free to ask the doctor whether he or she uses treatment guidelines, such as the NCCN Guidelines or other recognized

clinical practice guidelines.• Ask the doctor speci c questions about treatment options, such as: - How long it will take to complete all of the treatments? - Will I be able to work or perform other normal activities during treatment? - Will the side effects of treatment be temporary or permanent? - What is the chance that the cancer will come back? - How much will the treatment cost and how can I nd out how much my insurance will cover?• You may want to ask the doctor whether participating in a clinical trial would be helpful (see page 39).• If you smoke, it is important to stop now. Talk to your doctor or call 1-800-QUIT NOW (1-800-784-8669) to nd a “Quitline” in your area.• You might want to discuss living wills or advanced directives with your cancer care team.• Treatment options for lung cancer consist of surgery, radiation therapy, chemotherapy, and targeted therapy, which can

be given in different orders, or combinations, according to the tumor stage. You will probably want to know which treatments you will receiveand in what order they will be given.

• Your treatment will depend on how large your tumor is and whether it involves other parts of the lung or lymph nodes or has spread beyondthe lungs. This is called the stage of your lung cancer (see Lung Cancer Staging, page 9). The cancer stage is important to know becausetreatment will be based on it. For this reason, the treatment pathways in this guideline are also organized by stage.

Lung Cancer StagingThere are four general categories of treatment for non-small cell lung cancer: surgery, radiation therapy, chemotherapy, andtargeted therapy. These therapies can be used in different orders and combinations. A key factor in determining how to bestcombine these options is the stage of the cancer. The stages of lung cancer can be broadly subdivided into stages I, II, III, andIV. Each of these stages (I–IV) denes tumors that have similar prognoses and can be treated in the same general way. Eachtumor stage contains tumors with specic combinations of tumor size (T), lymph node involvement (N), and metastases (M).Different imaging tests (see page 12) are initially used to stage the cancer, often followed by biopsy techniques to conrm theimaging results. After this workup has been completed, the cancer can be categorized according to its stage and specic TNMstatus. To follow the treatment pathways, it is important to know both the cancer stage and TNM classication. Below is moredetailed information on the denitions of the T, N, and M categories and cancer staging.

T CategoriesT categories are based on the size of the lung cancer, its location within the lungs, and its spread to nearby tissues.

Tis: Cancer is found only in the layer of cells lining the air passages and has not spread into other lung tissues.This stage is also known as carcinoma in situ.

T1: The cancer is 3 cm or smaller in size, surrounded by lung or visceral pleura (membranes that surround the lungs), and does not affect themain branches of the airways. T1 is further subdivided into:

• T1a cancer is 2 cm or smaller • T1b cancer is larger than 2 cm and smaller or equal to 3 cm

T2: The cancer is larger than 3 cm but no larger than 7 cm in greatest dimension with any of the following features:• It involves a main bronchus but is not closer than 2 cm to the point where the trachea (windpipe) branches into the left and

right main bronchi.• It has spread to the membranes that surround the lungs.• The cancer may partially block the airways, but this has not caused the entire lung to collapse or pneumonia to develop.

T2 is further subdivided into: • T2a cancer is larger than 3 cm but smaller or equal to 5 cm • T2b cancer is larger than 5 cm but smaller or equal to 7 cm

T3: The cancer is larger than 7 cm in greatest dimension, with any of the following features: • It has spread to the chest wall, the diaphragm (breathing muscle that separates the chest from the abdomen), the mediastinal pleura

(membranes surrounding the space between the lungs), or parietal pericardium (membranes of the sac surrounding the heart).• It involves a main airway, and it is closer than 2 cm to the point where the trachea (windpipe) branches into the left and right main

airway but does not involve this area.• It has grown into the airways enough to cause one lung to entirely collapse or to cause pneumonia of the entire lung.• There is a separate tumor nodule in the same lobe.

T4: The cancer has one or more of the following features:• It has spread to the mediastinum (space behind the chest bone and in front of the heart), heart, blood vessels near the heart,

trachea (windpipe), nerve near the trachea, esophagus (tube connecting the throat to the stomach), backbone, or point where thewindpipe branches into the left and right main airway.

• Two or more separate tumor nodules are present in a different lobe of the same lung.

N CategoriesN categories depend on which, if any, of the lymph nodes near the lungs are affected by the cancer.

N0: The cancer has not spread to lymph nodes.N1: The cancer has spread to the lymph nodes either in the lung or located around the area where the bronchus enters the

lung. Affected lymph nodes are present only on the same side as the cancerous lung.N2: The cancer has spread to subcarinal lymph nodes (around the point where the windpipe branches into the left and right

bronchi) or to lymph nodes in the mediastinum. Affected lymph nodes are on the same side of the cancerous lung.N3: The cancer has spread to lymph nodes near the collarbone on either side, and/or to hilar or mediastinal lymph nodes onthe side opposite the lung with the tumor.



11

M CategoriesM categories depend on whether the cancer has spread to any distant tissues and organs.

M0: No distant cancer spread.M1: Cancer has spread to one or more distant sites. Sites considered distant include other lobes of the lungs, lymph nodes

further than those mentioned in N stages, and other organs or tissues such as the liver, bones, or brain. M1 is furthersubdivided into the following categories:

• M1a: Include any of the following: - Separate tumor nodules in a contralateral lobe - Tumor nodules on the lining of the lung surface (i.e., pleura) - Fluid around the lungs or heart that contains cancer cells (i.e., pleural or pericardial effusion)

• M1b: Distant spread

Patient has beendiagnosed with non-small cell lungcancer based ontest results

· Pathology review or descriptionof cells and tissues made by apathologist based onmicroscopic features

· Medical history (i.e., cough,chest pain, weight loss) andphysical exam to assessgeneral health and cancersymptoms

· Series of images known as a CTscan of the chest, upperabdomen, and adrenal glands

· Complete blood count, alsocalled CBC. A test to check thenumber of red blood cells, whiteblood cells, and platelets in asample of blood.

· Blood chemistry tests, aprocedure in which a sample ofblood is examined to measure

the amounts of certainsubstances made within thebody

· Counseling on stoppingsmoking

Staging is usuallybased on the size ofthe tumor (T), whetherlymph nodes containcancer (N), andwhether the cancerhas spread from theoriginal site to otherparts of the body (M).

Additional testing may berequired prior to receivingtreatment based upon thestage of your cancer.Review the staging tableswith your doctor todetermine your clinicalstage. Follow theappropriate treatmentpathway for your specificclinical stage

NCCN Guidelines for Patients™: Non-Small Cell Lung CancerGeneral Principles of Pathologic Evaluation and Treatment

General Principles of Pathologic Evaluation

The purpose of examining the tissue removed during a biopsy or surgery is to classify the type of lung cancer, determine the extent ofinvasion, assess the edges of the specimen are free of cancer or if any cancer cells remain in the surgical margins, and determine themolecular abnormalities of lung cancer that may be able to predict for sensitivity and resistance to epidermal growth factor receptor-tyrosine-kinase inhibitors (EGFR-TKI).The World Health Organization (WHO) tumor classification system provides the foundation for tumor diagnosis, patient therapy, and clinicalstudies.The surgical pathology report should include the histologic classification published by the WHO for lung cancer.

General Principles of Surgical TherapyDetermination of whether a tumor can be removed by surgery should be performed by board-certified thoracic surgeons who perform lungcancer surgery as their main duty in their practice.Complete surgical removal is preferred over ablation (destruction of a body part or tissue or its function).It is important that the overall tr eatment plan be discussed and decided, along with all necessary imaging tests prior to any non-emergencytreatment.

General Principles of Radiation TherapyRadiation therapy can be offered as additional therapy for operable patients whose cancer can be completely removed with surgery.Radiation therapy may be offered as the primary local treatment for patients in order to shrink the tumor so they can have surgery.Radiation therapy is an important component of palliative treatment for patients with incurable disease. It can be given locally in the chestarea as well as to distant sites outside the chest as palliative care for stage IV patients with widespread disease.

General Principles of Chemotherapy or ChemoradiationChemotherapy is also referred to as systemic therapy.In patients with early stage lung cancer, chemotherapy/chemoradiation is recommended as additional therapy for patients high-risk features

or if there is cancer in the edges of the surgical specimen.Chemotherapy/chemoradiation may be given to shrink a tumor prior to surgery this is referred to as induction or neoadjuvant therapy.For advanced or widespread disease, chemotherapy prolongs survival, improves symptom control, and improves over all quality of life. Maybe given as first-line therapy, maintenance therapy, second-line therapy and even third-line therapy.Chemotherapy may be used as maintenance therapy. Continuation maintenance refers to the use of at least one of the agents given in firstline therapy to patients who have received 4-6 cycles and have not had disease progression. Switch maintenance refers to using a differentchemotherapy agent, not included as part of the first-line combination to patients who have received 4-6 cycles and have not had diseaseprogression.Second- or third-line therapy is for patients who have experienced disease progression during or after first-line therapy.Best supportive care should be provided to patients with poor performance status and progressive disease during any stage of the treatment.

Treatment recommendations should be made after joint consultation and/or discussion by a multidisciplinary team including surgicaloncologists, radiation oncologists, medical oncologists, pulmonologists, and diagnostic radiologists.

NCCN Guidelines for Patients™: Non-Small Cell Lung CancerLung Cancer Prevention and Screening

More than 90 percent of cases are caused by voluntary or involuntary (second hand) cigarette smoking. Smoking harms nearly everyorgan in the body.

Reports from the Surgeon General on both active smoking and second-hand smoke show that both cause lung cancer. (These reports areavailable on-line at .) The evidence shows a 20 to 30percent increase in the risk of lung cancer from second-hand smoke exposure associated with living with a smoker (To review theevidence on-line go to .) Every person should beinformed of the health consequences, addictive nature, and risk of dying posed by tobacco consumption and exposure to tobacco smokeand effective legislative, executive, administrative, or other measures should be contemplated at the appropriate governmental level toprotect all persons from exposure to tobacco smoke. (To obtain more information on-line visit the website

).

Further complicating this problem, tobacco products which cause lung cancer, also contain the highly addictive substance, nicotine.Reduction in the number of deaths caused by lung cancer will require widespread implementation of the Agency for Healthcare Researchand Quality (AHRQ) Guidelines to identify, counsel, and treat patients who are addicted to nicotine. (To read more visit

)

Patients who are current or former smokers have a very high risk of developing lung cancer. The use of drugs, vitamins, or other agentsto try to reduce the risk of, or delay the development or recurrence of, cancer are not yet established for these patients. When possible,these patients should be encouraged to enroll in prevention trials.

At the present time, the NCCN Guidelines Panel recommends that high-risk individuals participate in a clinical trial evaluating CTscreening. If a trial is not available or the high-risk individual is not eligible for participation in a clinical trial, then the individual should goto a center of excellence with expertise (in radiology, pathology, cytology, thoracic surgery, and general expertise in lung cancertreatment) to discuss the potential risks and benefits before having a screening CT.

NCCN Guidelines for Patients™: Non-Small Cell Lung CancerDiscussion Version 2010Introduction

Anatomy of the Lungs: Relevant Aspects

The lungs are 2 sponge-like organs located on either side of the heart in the chest cavity. The right lung is divided into 3 lobes, while the left lungonly has 2. This is because the heart takes up more space on the left side of the chest than the right. When air is inhaled, it rst travels into thetrachea (windpipe) and then passes deeper into the bronchi of the lungs, which are the main airways of the lungs. The bronchi divide into smallerand smaller airways. Finally, the inhaled air ends up in tiny sac-like structures, called the alveoli. In the alveoli, the air comes into contact with theblood vessels that line the thin walls of these structures. Oxygen then passes through the walls of the alveoli and enters theblood stream, whilecarbon dioxide, a waste product, leaves the blood stream, enters the alveoli, and is exhaled. Most lung cancers start in the lining of the bronchi,but they can also begin in other areas, such as the trachea, smaller airways, or alveoli. The lining around the lungs, called the pleura, helpsprotect the lungs and allows them to move with each breath. There are 2 parts of the pleura: the visceral pleura, which is attached to the lung,and the parietal pleura, attached to the chest wall. Normally they are attached together.

Lymph is a clear uid that contains tissue waste products and immune system cells. Lymph uid circulates throughout the body in vessels similar toveins, called lymphatic vessels, which transport the uid into structures called thelymph nodes. Lymph nodes are located around the bronchi andin the mediastinum, the area between the lungs; they are also a common site for lung cancer to spread. Whether or not the lymph nodes containcancer cells has a major impact on treatment options. For example, if lymph nodes are involved, surgery may be combined withchemotherapyor radiation therapy . Therefore, evaluation of the status of the lymph nodes either through imaging tests, such asPET/CT scans or CT scans, oractually taking a small piece of the lymph node to examine under a microscope (called a biopsy) is an important part of theinitial evaluation forlung cancer. Furthermore, the spread of cancer cells to the lymph nodes indicates a greater likelihood of spread to other areas of the body. Theimportance of the status of lymph nodes in the staging of lung cancer is elaborated upon in Lung Cancer Staging, page 9.

Types of Lung CancerMost cancers are named after the part of the body where the cancer rst starts. Thus, lung cancer begins in the lungs. Cancer that starts ina different part of the body can spread, or metastasize, to the lungs but that cancer is still named according to where it rst developed. Forexample, breast cancer can spread to the lungs but is called metastatic breast cancer, not lung cancer. These guidelines only address aspecic type of lung cancer, non-small cell lung cancer (NSCLC), which is the most common type of lung cancer, accounting for approximately85% of lung cancers. There are 3 subtypes within NSCLC, which can be distinguished by size, shape, and chemical make-up when examinedmicroscopically:

• squamous cell carcinoma (cancer)

• adenocarcinoma (including bronchioloalveolar carcinoma)

• large cell undifferentiated carcinoma

THE DIAGNOSIS OF NON-SMALL CELL LUNG CANCER

Medical History and Physical Exam

Lung cancer may rst be suspected based on ndings from a lung x-rayor scans performed for other reasons. Alternately, lung cancer can besuspected based on specic symptoms related to the lungs, such as a persistent cough. The rst step a doctor takes in diagnosing lung canceris performing a physical exam and taking a medical history, which consists of questions about the patient’s health and other risk factors thatincrease the risk for lung cancer, such as smoking. Any of thesymptoms displayed in Table 1 should be reported to a doctor right away.

Table 1 Important Symptoms*

Localized (Lung-Related) Symptoms Symptoms due to Metastasis or Spread

A cough that does not go away Bone pain

Chest pain, often made worse by deep breathing Weakness or numbness of the arms or legs

Shoulder pain with numbness in some ngers; Dizzinesswith (or without) a droopy eyelid

Hoarseness Yellow coloring of the skin and eyes (jaundice)

Weight loss and loss of appetite Lumps near the surface of the body, caused by cancer spread-ing to lymph nodes (often in the neck or above the collarbone)

Bloody or rust-colored sputum (spit or phlegm) Clusters of symptoms (paraneoplastic syndromes) that canpoint to a possible lung cancer

Shortness of breath

Fever without a known reason

Infections that keep coming back, such as bronchitis and pneumonia

New wheezing

Headaches, dizziness; change in vision or speech

Seizures

*As derived from the American Cancer Society.

A medical history and physical exam will give the physician a general overview of the state of a patient’s health, as well as determine ifthere are other health problems, such as emphysema or heart problems. If cancer is found, knowing about additional health problems will

be important for determining the best cancer treatment.



32

NCCN Guidelines for Patients™: Non-Small Cell Lung CancerDiscussion Version 2010Performance StatusIfchemotherapy is an available treatment option, it is important for the physician to assess the patient’s general health to determine if they cantolerate the side effects of chemotherapy or other treatments, which can be severe. This assessment is called aperformance status and is mostcommonly based on a scale called the Eastern Cooperative Oncology Group (ECOG) Performance Scale , which ranks the general health ofpeople with cancer on a scale of 0 to 4. A rank of 0 means that the patient has no symptoms and is able to do the same daily activities he orshe could do before being diagnosed with cancer. At the other end of the scale, a rank of 4 means that the patient cannot take care of his orher daily self-care activities, such as feeding, bathing, dressing, or going to the bathroom, and cannot get out of bed. A rank of 3 means thatthe patient can do some self-care activities but spends more than half of his or her waking hours in bed because of feeling sick or weak. In thetreatment pathways, “good health” refers to an ECOG performance scale ranking of 0 to 1, intermediate health is 2, while “poor health” is aranking of 3 or 4.

ImagingImaging tests are an initial part of lung cancer workup used to determine the size and extent of the tumor. Imaging is a term that collectivelydescribes all the different tests that produce an image of an area inside the body, such as the lungs. Imaging tests for lung cancer include a chestx-ray and other, more sophisticated, tests such as the computed tomography (CT) scan ormagnetic resonance imaging (MRI) . Additional imagingtests, such as a positron emission tomography (PET) scan or bone scan, use very small doses of radioactive material to produce an image A PETscan can be combined with a CT scan (PET/CT) to better determine the location of an abnormality. Technicians will perform these tests, whichare then read by radiologists. Imaging tests will be performed throughout lung cancer treatment as routine follow-up to assess response of thetumor to treatment and to check for anyrecurrence . Further information for the above-mentioned imaging tests is discussed in the following sections.

CT ScanComputed or computerized tomography (CT), also referred to as a CT orCAT scan, is commonly used to image the lungs as part of the initialevaluation of lung cancer; it is also often used to image other parts of the body, such as the brain and liver, to determine the tumor’s size andlocation and to identify enlarged lymph nodes. A CT scanner looks like a large box with a hole in the center, creating the effect of a short tunnel.

If you have a CT scan, you will lie still on a table that is moved into the center of the tunnel, and the x-ray tube will rotate around you taking aseries of pictures from different angles. You may hear slight buzzing, clicking, or whirring sounds. Atechnician will be sitting in a separate roomto operate the scanner. Although you will be alone in the examination room, the technician will be able to see, hear, and speak with you at alltimes.

Sometimes a dye, known as contrast material, is injected into a vein (i.e., an intravenous injectionor IV) in order to produce a more detailedimage. Some people may experience a reaction to the contrast that feels like a ushing sensation during the injection and a metallic taste in themouth. Some people may have a mild allergic reaction, such as hives. In very rare cases, some people will have very severe reactions, such aswheezing or trouble breathing that requires further treatment. Be sure to tell the doctor if you have ever had a reaction to any contrast materialused for x-rays.

33

NCCN Guidelines for Patients™: Non-Small Cell Lung CancerDiscussion Version 2010MRI ScanMagnetic resonance imaging (MRI) scans use radio waves and a powerful magnet linked to a computer to create detailed pictures of areas insidethe body. MRIs are especially useful for imaging the brain, spine, soft tissues of the joints, and inside the bones. Similar to a CT scan, a liquidcontrast material may be injected into a vein in order to improve the image.

In an MRI scan, you will be asked to lie absolutely still on a table that will move to the center of the MRI machine. The inside of the machineis like a well-lit tunnel, and you will hear the MRI machine making a knocking noise as it moves around you. The technician may give you earplugs or head phones if this noise is disturbing. Patients should tell the technician if they have signicant problems with claustrophobia. Someradiology departments have different types of MRI machines that are open at the top to minimize claustrophobia, and some people may benetfrom a sedative before the exam. Like a CT scan, you will be alone in the examination room, but the technician will be able to see, hear, andtalk to you during the procedure.

Bone ScanBone scans help show if cancer has spread to the bones. You will get a low dose injection of radioactive material (usually called technetium

diphosphonate), which causes no long-term effects. The injected radioactive substance is attracted to diseased bone cells throughout the entireskeleton. A special gamma camera will take pictures of the radioactive material in the bones. Areas of diseased bone will be seen on the bonescan image as dense, gray to black areas, called “hot spots.” These areas may suggest the presence of metastatic cancer, but they could alsosuggest the presence of arthritis, infection, or other bone diseases, which can cause a similar pattern.

PET/CT ScanA PET/CT scan is a unique type of image because the PET component provides information on how the tumor is functioning, while the CT com-ponent provides information on where the tumor is located. The PET scan uses a form of sugar (glucose) that contains a radioactive atom, whichis injected intravenously. Because tumors typically require more energy than normal cells, the tumor will absorb more of the radioactive sugar.Using a special camera to detect the radiation, areas of tumor will show up as bright spots on the image. The CT component of the scan willthen show exactly where the tumor is located. PET/CT scans are commonly used in the initial evaluation of lung cancer, particularly to determinewhether or not the cancer has spread to the lymph nodes between the lungs, as well as to distant sites such as the liver, bone, or adrenal glands.

Procedures Used to Diagnose and Check for Spread of Lung Cancer

As previously discussed in the staging section (page 9), the initial evaluation of lung cancer is designed to determine the tumor’s size and loca-tion. The imaging tests previously described accomplish this by providing an image of the cancer and its surrounding anatomy. However, beforemaking nal treatment decisions,oncologists typically want to conrm the imaging results with a biopsy. A pathologist will examine the specimencollected and determine if cancer cells are present. If you have any questions about the results of yourpathology report or diagnostic tests, do nothesitate to ask your doctor. You can also get a second opinion on the pathology report, called a pathology review, by having the tissue specimensent to a consulting pathologist at an NCCN Member Institution (to nd an institution, visit NCCN.com) or another laboratory recommended by

your physician.

34

NCCN Guidelines for Patients™: Non-Small Cell Lung CancerDiscussion Version 2010There are a variety of ways that cells can be collected for microscopic examination, depending on the tumor location. These are described in thefollowing sections.

Sputum Cytology

Lung cancer develops in the lining of the airways, and cancer cells shed from the tumor become mixed in with mucus, also known as sputum, thatis normally present in the lungs. Therefore, a sample of phlegm (mucus coughed up from the lungs) is examined under the microscope to see ifcancer cells are present. This is called a sputum cytology .

Biopsy TechniquesA biopsy refers to the removal of a sample of the tumor for examination by a pathologist. To obtain a specimen of the tumor, a procedureknown as a ne-needle aspiration biopsy may be performed by an interventional radiologist by inserting a needle into the tumor and extractingtumor cells. To safely insert the needle, the interventional radiologist will use an imaging procedure to guide the placement of the needle intothe tumor. For example, CT scans can be used to direct needle placement between the ribs and into the lung. If the tumor is near the windpipe(i.e., trachea) or lower (i.e., by the bronchi), a lighted exible tube called a bronchoscope (see Bronchoscopy, below) can be placed down the

throat to help guide the needle safely through the wall of the windpipe and into the tumor for sampling. This biopsy technique is often used if aprior imaging study nds enlarged lymph nodes where the windpipe branches into the right and left lungs. Sometimes it may be easiest to gainaccess to the enlarged nodes through the esophagus, the tube that extends down into the stomach. Radiologists also use sound waves(also called ultrasound ) to guide biopsies through the windpipe or esophagus.

BronchoscopyA bronchoscopy is a procedure that uses a bronchoscope to examine the inside of the trachea, bronchi, and lungs. This test is performedto examine the lining of the airways to determine if additional tumors are present; biopsies can then be taken from the lining of the airway.Additionally, a bronchoscope is used to provide access to lymph nodes near the airways. Once the correct spot has been identied with thehelp of an imaging procedure, then a needle can be placed through the wall of the airway into the target lymph node for sampling.

Mediastinoscopy Sometimes the initial imaging tests, such as a CT or PET/CT scan, will identify enlarged nodes in the mediastinum. Evaluation of the lymph nodesin this area, called the mediastinal lymph nodes, is a very important part of the initial evaluation for lung cancer. It is important for physicians tobiopsy these nodes to determine if they are cancerous because other conditions, such as infection, can also cause the nodes to become en-larged. The best way to reach these lymph nodes is by mediastinoscopy , a procedure similar in concept to a bronchoscopy since both involve theuse of a hollow, lighted tube. However, unlike a bronchoscopy where the tube is placed in the airway, for a mediastinoscopy the tube is placedunder the breastbone (sternum), through a small incision at the base of the neck. Special instruments operated through this tube are then used totake a biopsy from the enlarged nodes along the windpipe and the major airways.

Thoracoscopy

Like bronchoscopy and mediastinoscopy, athoracoscopy involves the use of a lighted tube to provide the physician a way to look directly into the

35

NCCN Guidelines for Patients™: Non-Small Cell Lung CancerDiscussion Version 2010body. A thoracoscopy uses a thin, lighted tube to look at the space between the lungs and chest wall, allowing the doctor to see tumors onthe surface of the lungs. The doctor can also take a biopsy of any suspicious areas through the use of the tube using specially designed tools.

Thoracentesis

The outside lining of the lung that separates the lung and the chest wall is called thepleura . If cancer is present in the pleura, uid may ll upbetween the lung (visceral pleura) and chest wall (parietal pleura), which can cause shortness of breath. However, other conditions can causeuid build-up, including infection or some heart conditions. Therefore, if uid is present, it is important to collect a sample for examination undera microscope to determine if cancer cells are present. This procedure is called a thoracentesis and involves placing a syringe between the ribsinto the chest cavity and sucking out a sample of the uid. If there is a lot of uid, its removal can help improve breathing.

Blood TestsCertain blood tests are often done to see if the lung cancer has spread, or metastasized, to the liver or bones and to determine the overall healthof vital organs, such as the liver or kidneys. These tests include acomplete blood count (CBC) and blood chemistry . A CBC determines whether thepatient’s blood has the correct number of various cell types. Doctors repeat this test regularly in patients treated with chemotherapy because

these drugs temporarily affect blood-forming cells of thebone marrow . Spread of cancer to the liver and bones may cause certain chemicalabnormalities in the blood. Blood chemistries are used to monitor the function of the kidneys and liver.

Types of Treatment for Non-Small Cell Lung CancerAfter a diagnosis of non-small cell lung cancer, there will be a lot to think about. The oncologist will help patients decide the best way to treat ormanage cancer. Lung cancer treatment planning is very complex and there may be more than 1 treatment to choose from. The basic options fortreatment include surgery, chemotherapy, radiation therapy, or targeted therapy, and each is described in detail below. Treatment may includevarious combinations of these therapies. A team of cancer care professionals should be available to discuss the options.

Patients should not feel rushed into making a decision; in fact, patients should feel free to get a second opinion on the proposed treatment planor to nd a cancer care team that they feel most comfortable with. (However, before making plans, it can be wise to check with the patient’shealth insurance company’s policy regarding second opinions.) If the rst doctor has done tests, the results can be sent to the second doctor sopatients will not have to undergo them again.

Surgery One of the rst considerations of treatment is whether or not the lung tumor can be removed with surgery. Determination of surgical eligibilityand type of surgery should be completed by a board-certied thoracic surgeon with extensive experience performing lung cancer surgery. Thesurgeon will determine surgical eligibility based on the size and location of the tumor and if nearby lymph nodes are involved. In general,surgery is not an option if the tumor has spread beyond the lungs to distant organs, such as the bones, brain, or liver. If the tumor is large orinvolves the adjacent lymph nodes, surgery may be delayed until after an initial cycle of chemotherapy and radiation therapy (chemoradiation)to shrink the tumor. This sequencing of therapy will depend on stage andTNM classication (pages 9–11 ).

D I S C U S S I O N



36

NCCN Guidelines for Patients™: Non-Small Cell Lung CancerDiscussion Version 2010The extent of surgery will also depend on the tumor size and the overall health of your lungs. Awedge resection (segmental resection) removesthe portion of the lung that includes the tumor and some surrounding tissue. If a lobe (section) of the lung is removed, the surgery is called alobectomy . If the entire lung is removed, the surgery is called apneumonectomy . Video-assisted thoracic surgery is a relatively new minimallyinvasive surgical procedure that is done primarily at large academic cancer centers.

Surgery may not be an option if breathing problems, such as emphysema, are present. Pulmonary function tests are always done beforesurgery to determine if the patient’s lungs can tolerate surgery. The lung tissue that is removed is called thesurgical specimen, which is sent toa pathologist for examination. The pathologist will check to see whether all the tumor has been removed by looking at the edge, ormargin,of the specimen. If the tumor is present at the margin, it is likely that not all the tumor was removed. The status of the surgical margins is animportant part of treatment planning after surgery.

Lung operations are performed while the patient is asleep under general anesthesia, and a hospital stay of about 1 week is usually needed. Thepatient will have some pain after the surgery because the surgeon will have to cut or spread the ribs to reach the lungs. There are many ways tocontrol this pain (see Palliative and Supportive Care, page 51 ).

After surgery, people who do not have lung problems other than the cancer can often return to their normal activities after a lobe or even anentire lung is removed. However, if they have other diseases, such as emphysema or chronic bronchitis (common among heavy smokers), theymay nd that their shortness of breath gets worse.

Radiation TherapyRadiation therapy uses high-energy rays, such as x-rays, to kill or shrink cancer cells. Theradiation may come from outside the body (external-beam radiation therapy ) or from radioactive materials placed directly in the tumor (internal or implant radiation, also calledbrachytherapy ).External radiation is most often used to treat lung cancer. Radiation therapy is often part of the initial treatment of lung cancer either before orafter surgery. Before surgery, it is used to shrink the tumor so that surgery can remove the entire tumor, or if the tumor is near other organs orblood vessels. After surgery, radiation therapy may be considered if there is concern that the surgery did not remove all the tumor. The radiationtherapy will then be aimed directly at the tumor and does not have widespread antitumor effects. This contrasts with chemotherapy, whichcirculates throughout the body. For this reason, radiation therapy is called a local therapy, while chemotherapy is called a systemic therapy.

ChemotherapyChemotherapy refers to the use of drugs to kill cancer cells. The drugs are usually injected intravenously while a few drugs are given by mouth,called oral chemotherapy. Once the drugs enter the bloodstream, they can reach all parts of the body, which is why chemotherapy is referredto as systemic therapy. Thus, chemotherapy can be used not only to shrink the tumor in the lung, but also to treat tumor cells that have spreadoutside the lung.

Different chemotherapies attack tumor cells in different ways; therefore, several drugs are often combined for a multi-pronged attack (combinationchemotherapy). A specic drug combination is called a chemotherapyregimen. Doctors who prescribe these drugs (calledmedical oncologists)

NCCN Guidelines for Patients™: Non-Small Cell Lung CancerDiscussion Version 2010• Etoposide (Toposar®; Vepesid®)

• Gemcitabine (Gemzar®)

• Vinblastine • Vinorelbine (Navelbine®)

• Pemetrexed (Alimta®)

When appropriate, some patients will receive carboplatin, another platinum-based drug, instead of cisplatin.

If the lung cancer recurs or metastasizes, chemotherapy is the principle treatment. Patients are given rst-line chemotherapy and this is continueduntil the tumor no longer responds, at which point a new combination of drugs will be considered, known as a second-line therapy. Drugs com-monly used for rst-line chemotherapy are similar to the ones used for initial therapy at surgery and include cisplatin or carboplatin in combina-tion with any of the following drugs: docetaxel, etoposide, gemcitabine,irinotecan (Camptosar®), paclitaxel (Taxol®), vinblastine, or vinorelbine.Erlotinib (Tarceva®), a type of targeted therapy (see below), is also an option for rst-line therapy. In patients who cannot tolerate combinationchemotherapy , single-agent chemotherapy (using just one drug) can be used. However, chemotherapy is not recommended for patients in poorgeneral health (performance status 3–4).

Second-line chemotherapy includes all the drugs discussed above, and also:

• Docetaxel alone

• Erlotinib alone (see Targeted Therapy, below)

• Pemetrexed alone

Targeted TherapyIn the past few years, lung cancer research has focused on a new class of drugs called “targeted therapy,” which are drugs designed to speci-cally attack cancer cells and interfere with their ability to grow. Targeted therapy can be combined with chemotherapy for lung cancer that hasspread beyond the lungs. One such drug is erlotinib, which is unique because the tumor tissue can be tested rst to see if the tumor cells have thetarget that predicts successful treatment with erlotinib. Erlotinib is taken by mouth, and common side effects include skin rash and diarrhea.

Bevacizumab (Avastin®) is another targeted therapy which specically targets blood vessels and is designed to choke off the blood supply to thetumor. A side effect of bevacizumab is bleeding, which means it should not be used in patients who are coughing up blood. Care must be takenwhen this drug is given to those whose cancer has spread to the brain or who are on blood thinners (anticoagulants). Other rare but serious sideeffects include blood clots and high blood pressure. Bevacizumab is given intravenously every 3 weeks along with chemotherapy.Cetuximab

NCCN Guidelines for Patients™: Non-Small Cell Lung CancerDiscussion Version 2010(Erbitux®) is designed to interrupt the growth of tumor cells and, similar to other targeted therapies, is combined with chemotherapy. It is givenintravenously, and common side effects include skin rash or diarrhea.

Combination Therapy

Lung cancer is often initially treated with combination therapy; that is, the combination of surgery with chemotherapy, or radiation therapy, orboth, given either before or after surgery. Chemotherapy and radiation therapy can be combined together in several different ways, referredto as chemoradiation. For example, chemotherapy and radiation therapy can be given sequentially. Typically the chemotherapy is given beforethe radiation therapy, but sometimes the radiation therapy may come rst. Occasionally, additional chemotherapy alone will be given afterchemoradiation. Concurrent chemoradiation is when chemotherapy and radiation therapy are given together. In the treatment pathwaysconcurrent chemoradiation is described as “chemotherapy together with radiation therapy.” The T and N status of the tumor are used todetermine whether combination therapy is needed.

Treatment recommendations should be made after a joint consultation and/or discussion by a multidisciplinary team including thoracic surgeons,radiation oncologists, medical oncologists, pulmonologists, pathologists, and diagnostic radiologists.

Complementary and Alternative TherapiesComplementary and alternative therapies and complementary and integrative medicine are therapies of proven or unproven efcacy that havebeen used to promote wellness, to manage symptoms associated with cancer and its treatment, or to treat cancer. When properly combined withstandard cancer treatments, some complementary therapies can enhance wellness and quality of life, but others may be harmful during or aftertreatment for cancer.

If you are undergoing cancer treatment, it is important that you tell your cancer care team of any alternative therapies that you are participatingin for 2 key reasons: 1) your cancer care team can help you determine which therapies may be helpful and which have no benet; and 2) sometherapies could potentially interfere with your medical treatment or cause side effects that will limit the effectiveness of your treatment.

About Clinical TrialsClinical trials are carefully controlled research studies that test whether a new treatment is safe and how effective it is or examine new waysof diagnosing or preventing a disease. Clinical trials may also focus on rening existing “standard” therapies. Most of the advances in cancertherapy have been the result of the participation of patients in clinical trials. NCCN endorses participation in clinical trials, and for patients,there are several advantages to participating. First, patients will receive state-of-the-art cancer care according to a very specic plan oftreatment. Second, physicians who participate in clinical trials are aware of the newest cancer treatments, keep careful track of all of theresults of treatment—both good and bad—and compare their results with other colleagues to further rene treatment strategies. After adiagnosis of lung cancer, patients have many decisions to make, and one of them may be whether or not to participate in a clinical trial.

Following is a brief overview of clinical trials. If you have lung cancer, talking to your health care team, your family, and your friends can help you make the best treatment choice for you.

NCCN Guidelines for Patients™: Non-Small Cell Lung CancerDiscussion Version 2010The Purpose of Clinical TrialsClinical trials are done to get a closer look at promising new treatments or procedures in patients. A clinical trial is only planned and begunwhen there is good reason to believe that the treatment, test, or procedure being studied may be better than the one used currently. Treatmentsused in clinical trials are often found to have real benets and may go on to become tomorrow’s standard treatment. NCCN is strongly commit-ted to clinical trials and believes that the best management for any patient with cancer is in a clinical trial.

Clinical trials can focus on many things, such as:

• New uses of drugs that are already approved by the U.S. Food and Drug Administration (FDA). For example, drugs that are used in one typeof cancer may be tested in another type of cancer, or different drugs may be combined together.

• Different ways of administering chemotherapy, such as using oral drugs instead of IVs.

• New drugs that have not yet been approved by the FDA, where research is being done to determine the best dosage that balances the sideeffects with effectiveness.

• Different types of radiation therapy, designed either to decrease the side effects of radiation therapy or allow higher, more effective doses ofradiation or both.

• Different types of surgery, some designed to be more “minimally invasive” to permit a faster recovery or to use different tools to destroytumors, such as lasers.

• Alternative medicines, such as herbs and vitamins.

• New diagnostic tests, such as genetic tests, to determine which patients are the best candidates for certain therapies or to determine whether aparticular chemotherapy regimen is likely to be effective for a certain subset of patients.

• Medicines or procedures to relieve symptoms or improve comfort.

Phases of Clinical TrialsThere are 4 phases of clinical trials, which are numbered I, II, III, and IV, and are described below, using the example of a drug therapy.

Phase I Clinical Trials: The purpose of a phase I study is to nd the best way to give a new treatment to patients safely. The cancer care teamwill closely watch patients for any harmful side effects.

In phase I studies, the drug has already been tested in lab and animal studies, but the drug needs to be tested in humans to understand the opti-mal dose balanced against the potential side effects. Since phase I trials represent the earliest type of trial in humans, most patients in these trialshave not been successfully treated with other “standard” chemotherapies. Doctors start by giving very low doses of the drug to the rst patientsand increase the doses for later groups of patients until side effects appear or the desired effect is seen. Doctors are hoping to help patients,but the main purpose of a phase I trial is to test the safety of the drug. If a drug is found to be reasonably safe in phase I studies, it can then be

tested in a phase II clinical trial.

D I S C U S S I O N



41

NCCN Guidelines for Patients™: Non-Small Cell Lung CancerDiscussion Version 2010Phase II Clinical Trials: These studies are designed to determine if the drug works for a specic type of cancer, such as non-small cell lungcancer. Frequently, phase II trials involve new combinations of drugs. Patients are closely watched for an effect on the cancer, which is often de-termined with different imaging studies (i.e., x-rays, CT, or MRI) to see if the tumor is shrinking. The cancer care team also looks for side effects.

Phase II trials are done in larger groups of patients when standard treatments aren’t working. If a drug or combination of drugs is found to beeffective in phase II studies, it can be tested in a phase III clinical trial.

Phase III Clinical Trials: Phase III studies involve large numbers of patients. Often, these arerandomized clinical trials, which means thatpatients are randomly put in 1 of 2 (or more) treatment groups. One group (called the control group) receives the standard, most acceptedtreatment. Other groups get the new treatment or treatments being studied. Neither the patient nor physician can pick which group they want tobe in, which may make some patients uneasy. However, the doctor will explain the exact rationale for the clinical trial and the risks and benetsof being assigned to either group. All patients in phase III studies are closely watched. The study will be stopped early if the side effects of thenew treatment are too severe or if one group has much better results than the others.

Phase III clinical trials are usually needed before the FDA will approve a new drug for use by the general public.

Phase IV Clinical Trials: Once a new drug has been approved by the FDA and is available for all patients, it may be studied in phase IVstudies in very large numbers of patients with different types of cancer. In this setting, more can be learned about short-term and long-term sideeffects and safety of the drug. For example, some rare side effects may only become apparent in phase IV studies. Doctors can also learn moreabout how well the drug works, and if it might be helpful when used in other ways, such as in combination with other treatments.

Deciding to Enter a Clinical TrialIf you have lung cancer and are interested in taking part in a clinical trial, you should begin by asking your doctor if the clinic or hospitalparticipates in clinical trials. In order to interpret the results of a clinical trial, all the participants must be similar in terms of the tumor statusand general health, so the physician can be certain that any improvement in outcome is the result of treatment and not due to different patient

or tumor characteristics. Therefore, you will need to meet certain requirements in order to take part in any clinical trial. However, whether or not you enroll in a clinical trial is completely up to you.

Anyone participating in a clinical trial will need to sign a document called an “informed consent.” This informed consent describes the study indetail and outlines the potential risk and benets. Your doctors and health care team will explain all the details of the clinical trial, and why itmay be right for you. Your signature on the informed consent document means that you understand the risk and benets and agree to participatein the clinical trial. However, the informed consent does not mean that you must stay committed to the clinical trial; you can leave the clinical trialwhenever you want for any reason. It is also important to understand that participating in a clinical trial does not keep you from getting any othermedical care you may need.

• Is there a clinical trial that I could take part in?

• What is the purpose of the study?• What kinds of tests and treatments does the study involve?

• What does this treatment do? Has it been used before?

• Will I know which treatment I receive?

• What is likely to happen in my case with, or without, this new treatment?

• What are my other choices and their pros and cons?

• How could the study affect my daily activities?

• What side effects can I expect from the study? Can the side effects be controlled?

• Will I have to stay in the hospital? If so, how often and for how long?

• Will the study cost me anything? Will any of the treatment be free?

• If I am harmed as a result of the research, what treatment would I be entitled to?

• What type of long-term follow up care is part of the study?

• Has the treatment been used to treat other types of cancers?

Other Things to Consider During and After Treatment

Every patient’s reaction to a cancer diagnosis is different. Some patients may wish to defer entirely to the cancer care team and becomeminimally involved in treatment decisions. Others will want their family members to be involved in treatment decisions, while others will wantto take charge themselves. However, if you are a person with cancer, becoming actively involved in your care may improve your cancer careand recovery. For example, if you are aware of the side effects of treatment, you may be able to alert your cancer care team more promptly ifproblems emerge. It is also important to follow the scheduling of both chemotherapy and radiation therapy; missed appointments or doses can

D I S C U S S I O N



43

NCCN Guidelines for Patients™: Non-Small Cell Lung CancerDiscussion Version 2010affect the overall success of your treatment. Understanding the treatment and what it is trying to accomplish may make it easier to follow all thedetailed instructions and appointments that you will receive.

Good nutrition and an overall healthy lifestyle are also important factors in treatment. In particular, if you smoke, it is important that you take

steps to stop smoking now. Quitting will improve your overall health, and the full return of your sense of smell may help you enjoy a healthy dietduring recovery. If you use alcohol, limit how much you drink. Have no more than 1 or 2 drinks per day. Good nutrition can also help you getbetter after treatment. Eat a nutritious and balanced diet, with plenty of fruits, vegetables, and whole grain foods. If you are having nutritionproblems, ask your cancer care team if you may benet from talking with a dietician.

Cancer treatment can be exhausting, both emotionally and physically. For example, fatigue is a side effect of both chemotherapy and radiationtherapy, and lung cancer itself can cause fatigue. Therefore, it is important to get plenty of sleep at night. You will probably have many familymembers and friends who are eager to help; take advantage of their offers, but make sure you allow yourself plenty of time on your own duringthe day, if need be. You may have special strengths, such as a history of excellent nutrition and physical activity, a strong family support system,or a deep faith, and these strengths may make a difference in how you respond to cancer treatment. There are also experienced professionals in

mental health services, social work services, and pastoral services who may assist you and your family in coping with your illness.A cancer diagnosis and its treatment is a major life challenge, with an impact on you and everyone who cares for you. Before you get to thepoint where you feel overwhelmed, consider attending a meeting of a local support group.

EXPLANATION OF TREATMENT PATHWAYS

Initial Evaluation and Clinical Stage (based on page 12)The treatment pathways that accompany this text begin with a diagnosis of non-small cell lung cancer followed by the initial clinical evaluationor workup. The workup begins with a medical history and physical exam, with a focus on symptoms that may help determine if the cancer hasspread outside the lung. A review of the patient’s overall health and biopsy results will also be done. The tumor will also bestaged based on

its size, location, and spread to other sites, such as the lymph nodes or other organs (TNM Classication). For example, a chest CT scan willhelp to stage the tumor by showing its size and location and will allow the doctor to evaluate the lymph nodes within the chest. If the nodes areenlarged, they may contain cancer cells that have spread from the lung tumor.

If the cancer has metastasized, other common sites include the liver and adrenal glands; these should also be examined and blood tests shouldbe ordered to check their functionality. Blood tests will also be recommended to check how well your liver and kidneys are working and to makesure your blood cell counts are not too low. Low blood cell counts or problems with internal organs could mean a higher risk for problems andside effects of certain lung cancer treatments, so these tests must be done before your treatment begins. Additional blood test results can suggestthat the cancer has spread outside the lung. Depending on the results of the medical history, evaluation of symptoms, and physical exam, extratesting of the heart, lungs, kidneys, or other organs may be needed to check whether a patient is likely to have serious problems from certainlung cancer treatments. If the patient is a smoker, smoking cessation counseling should be recommended because it is crucial to the outcome ofcancer treatment.

D I S C U S S I O N



44

NCCN Guidelines for Patients™: Non-Small Cell Lung CancerDiscussion Version 2010Results from this initial clinical evaluation are used to determine the cancer stage, and based on this, additional tests may be needed beforetreatment is started to determine if the cancer has spread. These tests may include imaging studies (MRI scans, bone scans) or biopsies of thelungs, lymph nodes, or other organs. The cancer stage may change after the results of biopsies and surgery are available.

Stage I and II Pretreatment Evaluation (based on page 14)This treatment pathway focuses on the evaluation of stage I and some stage II cancers. These tumors are generally small and there may bespread to the lymph nodes from the lung. For more detailed information on staging, refer to pages 9–12.

For clinical stage T1 or T2, and N0 or N1, the guidelines recommend tests and scans to gure out if surgery is a good treatment option. Thesetests include a pulmonary function test to measure how well the lungs take in and exhale air and how efciently they transfer oxygen into theblood. A bronchoscopy is done to look for cancer in other parts of the lungs or to get tissue for biopsy and diagnosis. It is also important to deter-mine if the cancer has spread to nearby lymph nodes, which could affect whether surgery is a good treatment option. Treatment options used tocheck for cancer spread are a mediastinoscopy, which checks whether cancer has spread to the mediastinal lymph nodes, and an ultrasound. Anultrasound can also be used to evaluate lymph nodes by placing the ultrasound device down the throat (esophagus) orbronchi . The PET/CT scan

also shows mediastinal lymph nodes, as well as spread anywhere else in the body. An MRI of the brain is only recommended if stage II cancer ispresent, to rule out spread to the brain.

If there is no cancer in the mediastinal nodes and the cancer can be removed with surgery, treatment is discussed on page 15.

If there is no cancer in the mediastinal nodes or no distant spread but surgery cannot be performed because of other medical conditions, radia-tion therapy is an option that may provide a cure. Limited surgery is also an option.

If cancer is found in the mediastinal nodes, the tumor stage will be changed to stage III, and surgery may or may not be a good option. See thetreatment pathway on page 19 that t the correct T and N categories.

Stage I, II, and IIIA Treatment (based on page 15)If the initial results of the tests and scans show that the cancer has not spread, surgery is recommended to remove the tumor and see how far ithas grown and may have spread. The surgeon will make every effort to completely remove the tumor, since this offers the best chance for a cure.Lymph nodes near the lungs will also be removed and checked for cancer cells. More therapy, consisting of additional surgery, radiation therapy,or chemotherapy, will typically be considered if the surgeon was unable to remove the entire tumor, if there are positive margins, or if there is ahigh risk that the tumor has metastasized.

As previously discussed, radiation therapy and surgery are referred to as local therapies because they do not treat cancer that has spread outsidethe lung. Chemotherapy is a systemic therapy that can kill microscopic cancer cells that have spread beyond the lung because it enters the blood-stream. Thus, chemotherapy is more strongly recommended as the tumor size increases because a larger tumor size or spread to nearby lymphnodes is associated with a greater risk of spread beyond the lung (see General Principles of Pathologic Evaluation and Treatment on

page 27 for further information regarding radiation therapy and chemotherapy, respectively).

D I S C U S S I O N



45

NCCN Guidelines for Patients™: Non-Small Cell Lung CancerDiscussion Version 2010Some cancer cells can be left behind even when the surgeon removes all the cancer that was visible at the time of the operation. A negativesurgical margin (no cancer is found at the edges of the surgical specimen) is usually a sign that no cancer was left behind near where it wasremoved. A negative surgical margin does not guarantee a cure, however, because cancer cells may have spread to other areas of the bodybefore surgery.

The following recommendations are based on the results of surgery and examination of the surgical specimen under the microscope. They aresubdivided according to whether cancer was present at the edge of the tumor specimen.

When the Surgical Margins Are NegativeAfter surgery, observation is recommended only for T1, N0 and many T2, N0 tumors that have been completely removed with no cancerfound at the margin. Chemotherapy is also a consideration for T2 tumors that are called high risk because those tumors are more apt to havealready spread beyond the lung. High-risk factors are based on what the pathologist sees under the microscope and include a very abnormalappearance of the individual cancer cells, tumor cells involving nearby blood vessels, or very narrow surgical margins. Chemotherapy is alsorecommended for patients when the lymph nodes contain tumor cells.

Radiation is generally not recommended when the surgical margins are negative, since that suggests that all the cancer has been removed duringsurgery. There is one exception, though. If the cancer is staged at T1-T2, N1 (a tumor with involvement of lymph nodes near the lung), then theaddition of radiation depends on the presence of certain adverse, or unfavorable, factors, such as:

• the lymph nodes in the mediastinum cannot be evaluated as needed;

• the cancer has grown outside of the lymph nodes;

• there are many lymph nodes involved with cancer; or

• the margins may be very close to the edge of the cancer.

If no adverse factors are present and the surgical margins are negative, then only chemotherapy is recommended. If adverse factors arepresent, there is a higher risk that the surgery did not remove the entire tumor. In this case, chemotherapy alone or chemoradiation followed byadditional chemotherapy may be recommended. If the cancer has spread to the lymph nodes between the lungs or near the main bronchus,radiation therapy may be added to the chemotherapy.

When the Surgical Margins Are PositiveAdditional therapy is recommended when tumor cells are found at the margin of the surgical specimen. Additional surgery is one option, whichmay be combined with chemotherapy when the original tumor is larger (stage IB, IIA). For smaller tumors (stage IA), radiation alone is an option.As the tumor gets larger, or the lymph nodes are involved and the risk for spread beyond the lungs increases, radiation is given sequentially,followed by chemotherapy alone.

NCCN Guidelines for Patients™: Non-Small Cell Lung CancerDiscussion Version 2010Stage IIB and IIIA Pretreatment Evaluation (based on page 16)This section is for patients with tumors that invade the chest wall, either in the superior sulcus, which is the upper part of the lung, or elsewhere;or tumors that invade the main bronchus near the trachea. Lymph nodes near the tumor may or may not show cancer spread (N0 or N1). Be-cause these cancers are larger than those discussed above, an extensive evaluation is needed before treatment can be started to ensure that thecancer hasn’t spread to the mediastinal lymph nodes or distant sites in the body and to determine if the tumor can be removed with surgery.

Bronchoscopy is done to check for more tumors in other areas of the lungs. Mediastinoscopy is recommended to nd out if cancer has spreadto the mediastinal lymph nodes. MRI of the brain and, for superior sulcus tumors, the spine, is done to look for spread to these tissues. A PET/CTscan is also done to look for spread. Finally, if not already done, pulmonary function tests are recommended.

This treatment pathway refers to other pages with more specic details depending on the ndings of the previously discussed tests. If distantspread is found, the cancer is reclassied as M1 (for further information see page 23).

Stages IIB and IIIA Treatment (based on page 17)Tumors in the superior sulcus (very top part of the lung) often invade nerves and other tissues in that area. If the surgeon thinks the tumor can becompletely removed (it isresectable ), the recommendation is rst to give concurrent chemoradiation to shrink the tumor, followed by surgery andmore chemotherapy. If the tumor cannot be removed with surgery (it isunresectable ), then chemotherapy together with a full dose of radiationtherapy is recommended. In cases where the removal of the tumor is uncertain, chemoradiation is given followed by surgery and then morechemotherapy if the tumor becomes resectable. If the tumor remains unresectable, then radiation therapy is recommended as the primary thera-py, followed by chemotherapy.

Tumors growing into the chest wall, the main breathing tubes near the trachea, or the mediastinum may be treated with surgery rst, which is thepreferred treatment. Other options include chemotherapy alone or concurrent chemoradiation, both of which are followed by surgery.

If, after surgery, the margins are free of cancer, additional chemotherapy is recommended if it has not already been given. If the edges of the

specimen contain cancer, the options include either: 1) additional surgery followed by chemotherapy (if not already given), or 2) chemoradiationfollowed by chemotherapy alone (if not given initially).

Stages IIIA Pretreatment Evaluation (based on page 18)This treatment pathway discusses the evaluation of patients with stage IIIA cancers that appear to have spread to the mediastinal lymph nodes(N2), as well as those with minimal lymph node spread (N0-N1), or a separate smaller nodule in another part of the lung. Patients should havebronchoscopy and biopsy of mediastinal lymph nodes, either by mediastinoscopy or ne-needle aspiration. A PET/CT scan and MRI of the brainare done to look for distant spread. If not previously done, pulmonary function tests are also recommended. These tests will determine if the tumorcan be removed with surgery and whether or not chemotherapy and radiation are needed. Further treatment depends on the results of these tests.

Stage IIIA Treatment (based on page 19)Three different stages are described on page 19. The rst stage is T1–T3 with no cancer found in the biopsy of the mediastinal lymph nodes.Surgery with removal of the mediastinal nodes is recommended. If the cancer is completely removable and the mediastinal lymph nodes donot contain cancer (N0–1), then further treatment is described on pages 15 or 16, respectively. If cancer is found in mediastinal lymph nodes(N2) and the surgical margins do not contain cancer, chemotherapy may be given with radiation therapy. If the margins do contain cancer,chemoradiation with additional chemotherapy is recommended. If the original tumor cannot be completely removed, the tumor should be treatedaccording to the stage as described on page 15.

The next 2 groups include patients whose tumors have spread to the mediastinal lymph nodes on the same side as the tumor (N2). The rstgroup contains patients with smaller tumors (T1–T2) and larger tumors (T3) that have not spread to adjacent structures. If the brain MRI andPET/CT scan do not show cancer spread, there are 2 options: chemotherapy together with a full dose of radiation therapy, or a short course ofchemotherapy with or without radiation can be given to determine if surgery is possible. If there is no disease progression during this treatment,surgery with or without chemotherapy and with or without radiation (if not given before) is an option. If there is tumor growth, then surgery is notan option, and radiation therapy with the option of chemotherapy is recommended. If there is no distant spread, radiation can be given (if not

given already) with or without chemotherapy.

The second patient group is those with T3 tumors that have spread into adjacent structures, such as the diaphragm or lining of the heart or lungs.Surgery is not an option for these patients. If the MRI and PET/CT scans show no evidence of distant spread, patients can be initially treated withchemotherapy together with a full course of radiation therapy.

Treatment of Separate Nodules, Stage IV, IIIA (T4, N0-1) (based on page 20)The upper 2 pathways on page 20 describe the the treatment options when there is an additional site of cancer in either the same oropposite lung. The smaller tumors, called satellite tumors, are a result of tumor spread within the lung. Whenever possible, the surgeon triesto remove the tumor and any satellite tumors. If this is successful and the margins of the surgical specimen are negative, then chemotherapyis recommended after the surgery. If the margins are positive, chemoradiation is recommended.

If the satellite tumor is located in the other lung, surgery is still recommended, and the tumors can be treated as 2 distinct primary tumors(see evaluation for these tumors on page 12).

The bottom pathway describes treatment when the surgeon concludes that complete removal of the tumor is not possible and there is no uid inthe chest; concurrent chemoradiation is recommended, followed by additional chemotherapy.

Stage IIIB Pretreatment Evaluation and Initial Treatment (based on page 21)This treatment pathway describes the workup and treatment for patients who appear to have cancer that has spread to lymph nodes on theopposite side of the mediastinum or above the collar bone (N3); N3 disease must be conrmed through a biopsy of any suspicious lymph nodes.A variety of techniques may be used, based on the location of the suspicious nodes. A mediastinoscopy ormediastinotomy can be performed to

D I S C U S S I O N



48

NCCN Guidelines for Patients™: Non-Small Cell Lung CancerDiscussion Version 2010evaluate the mediastinal nodes. A thoracoscopy is done to look for cancer cells in the space between the lungs and chest wall, and lymph nodesor any suspicious looking area can be biopsied at this time.

A ne-needle aspiration can also be performed using an imaging test to guide the needle placement. An ultrasound device, placed in either

the bronchus or esophagus can be used to guide a biopsy. PET/CT scan, brain MRI, and pulmonary function tests may also be performed. If allthese tests are normal, meaning the enlarged lymph nodes do not contain cancer cells and there is no distant spread, and the patient had ad-equate lung function, then the cancer is treatable with surgery (see page 13). If the biopsies do show cancer but there is no distant spread, thenchemoradiation is recommended, which may be followed by more chemotherapy. If the tests show distant spread, then treatment for widespreaddisease should be considered, as outlined on page 23.

Stage IIIB, Stage IV, M1a: Pretreatment Evaluation and Initial Treatment (based on page 22)Two different types of T4 tumors are discussed in this treatment pathway. T4 staging means that the cancer has spread to other structures in thechest or it is producing uid that surrounds the lung (pleural effusion) or heart (pericardial effusion).

If a T4 tumor with wide spread to lymph nodes is suspected (N2 or N3), then these nodes should be biopsied using mediastinoscopy or withne-needle aspiration, or the biopsy should be guided by ultrasound. Examining the chest using thoracoscopy will give information regardinghow far the cancer has grown. Tests to look for spread outside the chest (brain MRI and PET/CT scan) should also be performed.

If the lymph nodes do not contain cancer, the cancer is classied as T4, N0-N1 and may be treated with surgery or as recommended on page18. If the lymph nodes on the same or opposite side of the chest do contain cancer (N2-N3), then concurrent chemoradiation, followed by ad-ditional chemotherapy is recommended. Finally, if the tests show that cancer has spread outside the chest to distant sites, treatment should be asshown on page 23.

If there is uid around the lungs or heart (stage IV, M1a), a sample of the uid can be removed by placing a needle between the ribs andinto the area surrounding the heart or lungs. The uid is then checked under a microscope to see if cancer cells are present. If cancer can’t bediagnosed from cells in the uid, it may be necessary to perform a thoracoscopy to make sure that the uid is not related to cancer spread to thelining of the chest. If there are no cancer cells in the uid, then the cancer should be treated according to its T and N stage as discussed on page13. If cancer cells are present in the uid, surgery is not an option. The uid should be drained with a catheter (a tube used to withdrawuids), and a small piece of the sac around the heart may need to be removed to prevent the build-up of pressure. Treatment should then begiven as for stage IV disease (see page 23).

Stage IV Pretreatment Evaluation and Initial Treatment for Multiple Lung Primaries (based on page 23)Sometimes there is only 1 tumor nodule in 1 site of distant disease spread. This can only be determined after a complete evaluation withmediastinoscopy, bronchoscopy, brain MRI, and PET/CT scan. Treatment options depend on the site ofmetastasis.

If the cancer has spread only to the brain and there is only 1 tumor, surgery followed by radiation therapy is an available option. Two different

types of radiation therapy may be recommended. Radiation therapy to the entire brain (whole-brain radiation therapy ) is one option.

D I S C U S S I O N



49


Whole-brain radiation therapy is used to treat very small tumor spread that cannot be detected on brain MRI or PET/CT scan.Stereotacticradiosurgery is the second option for radiation therapy and can be focused specically at the site where the metastasis was removed.Whole-brain radiation therapy may be followed by stereotactic radiosurgery. As another option, stereotactic radiosurgery can be the rsttreatment instead of surgery, followed by whole-brain radiation therapy. After treatment of the brain metastases, surgical removal of the lungtumor depends on its stage, as noted in the treatment pathway.

If the cancer has only spread to 1 adrenal gland ( located in the abdomen), and this is conrmed through biopsy and is staged T1–T2, N0–N1or T3, N0 (which means it can be completely removed by surgery), then both the adrenal gland tumors and the lung cancer can be removedor treatment for stage IV cancer (see page 25) can be given. Additional treatment depends on the disease stage. Radiation therapy is also anoption for treating cancer in the adrenal gland.

Sometimes there is a separate cancer in another lobe of the lung or in the other lung. Both tumors should be removed if there is no lymphnode involvement or distant spread of cancer. If there are multiple sites of spread, then surgery is not recommended. For further treatmentrecommendations, see page 25.

Follow-Up, Recurrence, and Widespread Disease (based on page 24)After initial treatment with surgery, chemotherapy, and/or radiation therapy, the guidelines recommend regular follow-up tests and exams(physical exam and chest CT scan) to check for recurrence. Tumors may recur locally (in the lung), regionally (near the lungs), or distantly(in distant organs).

If the tumor recurs in or near the lung, treatment depends on exactly where it is located and what symptoms it may be causing. Recurrent tumorsmay occur in the airways and block breathing passages. Treatment options include vaporizing the tumor with a laser; placing a stent insidethe airway to keep it open; radiation therapy, with either brachytherapy (placing a small radioactive pellet inside the airway) or external-beamradiation therapy; and photodynamic therapy . Photodynamic therapy is the use of drugs that collect inside cancer cells and are activated byshining a special light on the tumor (see Palliative and Supportive Care, page 51).

Surgery to remove the recurrence may be an option in some cases, as is radiation therapy. If the tumor is located in the mediastinal lymph nodes,chemoradiation is recommended, but only if radiation therapy has not been previously given.

If the cancer is pressing on the large vein leading to the heart (the superior vena cava ), a stent can be placed inside the vein to prevent it fromcollapsing. Radiation therapy is another option for shrinking tumors pressing on this vein. When cancer presses on or collapses this vein, bloodow from the head and arms is reduced, possibly resulting in uncomfortable severe swelling in both the face and arms.

If the tumor is causing bleeding into the airways, treatment options are similar to when the airway is blocked, but bleeding can also becontrolled by blocking off the blood supply to the tumor, calledembolization.

D I S C U S S I O N



50

NCCN Guidelines for Patients™: Non-Small Cell Lung CancerDiscussion Version 2010If the lung cancer comes back at only 1 distant site, treatment options depend on the number and location of these recurrent tumors.If only 1 tumor is found, surgery to remove it may be an option (see page 23).

If there is spread to distant organs or more than one brain metastasis, external-beam radiation therapy is used to relieve symptoms. If cancer has

spread to the bones and is causing pain, external-beam radiation therapy can also be used to help relieve the pain. If the disease has weakenedthe bone enough that a fracture may occur, doctors may recommend surgery to strengthen it. This can help relieve pain and may allow thepatient to resume usual activities. Drug therapy may also be used to strengthen bones weakened by the tumor.

Although these treatments are described in the section on follow-up and recurrence, they also apply to patients who have distant metastasesfound at rst diagnosis. Doctors may also recommend systemic therapy (usually chemotherapy; see page 25).

Stage IV and Treatment of Recurrence (based on pages 25 and 26)This treatment pathway focuses on the role of chemotherapy and how long the treatments should continue. Because chemotherapy can causesevere side effects, it is recommended only for patients in relatively good health. In patients in very poor health, chemotherapy may cause seriousor life-threatening complications.

In deciding which patients should receive chemotherapy, NCCN doctors use precise denitions of good health or poor health based on theEastern Cooperative Oncology Group (ECOG) Performance Scale (see page 32 for more information).

NCCN recommends chemotherapy for patients with widespread disease who are in good health (performance status of 0–1). A variety ofdifferent chemotherapy options are available, which can be combined with a different type of systemic therapy called targeted therapy.

Chemotherapy is not designed to distinguish between normal cells and cancer cells, while targeted therapy is specically designed to attackthe cancer cells. Three different targeted therapies are used to treat lung cancer: bevacizumab, cetuximab, and erlotinib. Bevacizumab, whichis combined with chemotherapy, is specically designed to attack the blood vessels that feed the tumor. An increased risk of bleeding is a sideeffect of bevacizumab, so this drug cannot be used in patients who are using blood thinning drugs or who have any history of coughing upblood. In addition, the risk of bleeding is higher if the cancer has metastasized to the brain. Cetuximab is another targeted therapy that can becombined with chemotherapy. Erlotinib is the third targeted therapy and is a little bit different than bevacizumab or cetuximab since there isa test that can identify the specic tumors that will respond to this drug. The test is done on a piece of the tumor that was removed as partof surgery or with a biopsy. If this test is positive, patients are considered candidates for erlotinib, which is given by itself without additionalchemotherapy.

D I S C U S S I O N



51

NCCN Guidelines for Patients™: Non-Small Cell Lung CancerDiscussion Version 2010The same choices are generally recommended for patients in intermediate health (performance status of 2), though some chemotherapiesmay be favored over others. However, bevacizumab is not recommended for this group of patients.

Patients are usually evaluated after completing 2 cycles of therapy. If the cancer grows after the second cycle, the patient should be treated

according to the guidelines for progressive disease (see page 26). If the cancer shrinks or at least doesn’t grow after 2 treatments, chemotherapyshould be continued for 4 to 6 total cycles. Patients should have an evaluation after 6 cycles of chemotherapy. If the tumor has shrunk or doesnot spread and the patient is in good general health, the options are to continue getting the current treatment until the disease progresses, toget continuation maintenance therapy (meaning at least one of the drugs given as rst-line therapy is continued) or switch maintenance therapy(meaning that patients are switched to a different maintenance therapy), or to get continuing evaluation but not treatment (observation).

Chemotherapy is not recommended for patients in poor health (performance status of 3 or 4). Erlotinib therapy is an option orsupportive care can be considered. Supportive care is intended to relieve symptoms and to help keep patients as comfortable as possible; it is not intended todirectly attack or cure the cancer.

Although participation in clinical trials is a good option for any patient with lung cancer, a study of a very new treatment in the early stages oftesting (called a phase I or II clinical trial) may be a good option for patients whose disease progresses while on chemotherapy. Deciding on theright time to discontinue chemotherapy and focus on supportive care is never easy. Good communication with doctors, nurses, family, and clergy,as well as discussions with hospice staff, can help patients with cancer and their loved ones when facing this situation.

Stage IV with Disease Progression (based on page 26)Treatment after the cancer has begun to grow again is discussed in the treatment pathway on page 26. A different type of chemotherapy may begiven for those in good health (performance status of 0–2). Docetaxol, pemetrexed, or erlotinib are treatment options at this point. One categoryof chemotherapy is called “platinum” chemotherapy (meaning it contains derivatives of the metal platinum); a combination of 2 of these drugsmay be offered. If the tumor grows while the patient is taking any of these therapies, erlotinib can be given to patients who remain in goodhealth (performance status 0-2), but only if the patient has not already received this drug. If the tumor grows while the patient is receiving

erlotinib, treatment switches to supportive care. If the patient remains in good health, participation in a clinical trial is a consideration.Supportive care is recommended for patients in poor health (performance status 3–4).

Palliative and Supportive CareMost of these guidelines identify ways to cure some people with lung cancer or to help others live longer by removing or destroying lung cancercells. If you are a person with lung cancer, however, it is also important to realize that controlling symptoms and helping you continue to do thethings you want and need to do is another key goal. Do not hesitate to discuss your symptoms or how you are feeling with your cancer careteam. There are effective and safe ways to treat pain, most symptoms of lung cancer, and most of the side effects caused by lung cancer treat-ment. Care to help relieve symptoms caused either by the lung cancer or side effects from its treatment is calledpalliative care or supportive care.

The mediastinoscope is inserted into the chest through an incision above the breastbone.This procedure is usually done to get a tissue sample from the lymph nodes on the right side of the chest.

Mediastinotomy Mediastinotomy is similar to mediastinoscopy, except instead of using a lighted tube, an incision is made and the surgeon can directly examinethe mediastinum.

MediastinumThe area between the lungs. The organs in this area include the heart and its large blood vessels, the trachea, the esophagus, the thymus, andlymph nodes but not the lungs.

Medical oncologist

A doctor who specializes in diagnosing and treating cancer using chemotherapy, hormonal therapy, biological therapy, and targeted therapy. Amedical oncologist often is the main health care provider for someone who has cancer. A medical oncologist also gives supportive care and maycoordinate treatment given by other specialists.

MetastasisThe spread of cancer from one part of the body to another. A tumor formed by cells that have spread is called a “metastatic tumor” or a“metastasis.” The metastatic tumor contains cells that are like those in the original (primary) tumor. The plural form of metastasis is metastases.

MetastasizeTo spread from one part of the body to another. When cancer cells metastasize and form secondary tumors, the cells in the metastatic tumor arelike those in the original (primary) tumor.

MetastaticHaving to do with metastasis, which is the spread of cancer from the primary site (place where it started) to other places in the body.

Monoclonal antibodyA type of protein made in the laboratory that can bind to substances in the body, including tumor cells. There are many kinds of monoclonalantibodies. Each monoclonal antibody is made to nd one substance. Monoclonal antibodies are being used to treat some types of cancer andare being studied in the treatment of other types. They can be used alone or to carry drugs, toxins, or radioactive materials directly to a tumor.

NCCN Guidelines for Patients : Non-Small Cell Lung CancerGlossary MRI scanA procedure in which radio waves and a powerful magnet linked to a computer are used to create detailed pictures of areas inside the body.These pictures can show the difference between normal and diseased tissue. Magnetic resonance imaging makes better images of organs andsoft tissue than other scanning techniques, such as computed tomography (CT) or x-ray. Magnetic resonance imaging is especially useful for

imaging the brain, the spine, the soft tissue of joints, and the inside of bones. Also called MRI, NMRI, and nuclear magnetic resonance imaging.

Neoadjuvant therapyTreatment given as a rst step to shrink a tumor before the main treatment, which is usually surgery, is given. Examples of neoadjuvant therapyinclude chemotherapy, radiation therapy, and hormone therapy. It is a type of induction therapy. In lung cancer, neoadjuvant therapy describeschemotherapy or radiation therapy that is given before surgery in order to shrink the tumor.

NodeSee lymph node.

Non-small cell lung cancer

A group of lung cancers that are named for the kinds of cells found in the cancer and how the cells look under a microscope. The three maintypes of non-small cell lung cancer are squamous cell carcinoma, large cell carcinoma, and adenocarcinoma. Non-small cell lung cancer is themost common kind of lung cancer, accounting for approximately 85% of lung cancers.

Pericardial effusion

An unusual amount of uid collected in the sac surrounding the heart.PET/CT (positron emission tomography/computerized tomography) scanAn imaging study using a radioactive material to look for cancer anywhere in the body. The PET scan involves the injection of glucosethat is attached to radioactive material, which accumulates in the tumor cells. This radioactivity lights up when using a special camera.The CT component of the test is designed to show exactly where the radioactive material is located.

PET scanA procedure in which a small amount of radioactive glucose (sugar) is injected into a vein, and a scanner is used to make detailed,computerized pictures of areas inside the body where the glucose is used. Because cancer cells often use more glucose than normal cells,the pictures can be used to nd cancer cells in the body. Also called positron emission tomography scan.

NCCN Guidelines for Patients : Non-Small Cell Lung CancerGlossary PleuraA thin layer of tissue that covers the lungs and lines the interior wall of the chest cavity. It protects and cushions the lungs. This tissue secretes asmall amount of uid that acts as a lubricant, allowing the lungs to move smoothly in the chest cavity while breathing. There are two parts to thepleura. The visceral pleura attaches to the lung; the parietal pleura attaches to the chest wall. There is a potential space between them where

uid can accumulate.

Pleural effusionAn unusual accumulation of uid between the thin layers of tissue (pleura) lining the lung and the wall of the chest cavity. The accumulation ofuid may be due to cancer spread to the pleural membranes or may be caused by other benign conditions.

Pneumonectomy Surgery to remove all of one lung. In a partial pneumonectomy, one or more lobes of a lung are removed.

PrognosisThe likely outcome or course of a disease; the chance of recovery or recurrence. For a patient with lung cancer, the prognosis depends, to alarge extent, on the cancer’s stage and cell type.

Pulmonary function testA test used to measure how well the lungs work. It measures how much air the lungs can hold and how quickly air is moved into and out of thelungs. It also measures how much oxygen is used and how much carbon dioxide is given off during breathing.

Radiationmay come from a machine outside the body (external-beam radiation therapy), or it may come from radioactive material placed in the body nearcancer cells (internal radiation therapy). Systemic radiation therapy uses a radioactive substance, such as a radiolabeled monoclonal antibody,

that travels in the blood to tissues throughout the body. Also called irradiation and radiotherapy.

Using chance to assign people to groups means that the groups will be similar and that the treatments theyreceive can be compared objectively. At the time of the trial, it is not known which treatment is best. It is the patient’s choice to be in a random-ized trial.

RecurTo come back or to return.

RecurrenceCancer that has recurred (come back), usually after a period of time during which the cancer could not be detected. The cancer may come backto the same place as the original (primary) tumor or to another place in the body. Patients with lung cancer are always checked with various teststo detect any possible recurrence as quickly as possible.

Red blood cellsA cell that carries oxygen to all parts of the body. Also called erythrocyte and RBC.

RegimenA treatment plan that species the dosage, the schedule, and the duration of treatment. For example, a chemotherapy regimen may includemultiple drugs that are given in combination over several cycles of therapy.

Stage

The extent of a cancer in the body. Staging is usually based on the size of the tumor, whether lymph nodes contain cancer, and whetherthe cancer has spread from the original site to other parts of the body. Determining the stage is essential for choosing the best treatment.The clinical stage describes the extent of disease present based on results of diagnostic tests and the physical examination. The pathologicalstage is determined after biopsy or surgery when the cancer cells have been looked at under a microscope.

StagingPerforming exams and tests to learn the extent of the cancer within the body, especially whether the disease has spread from the original site toother parts of the body. The system most often used to describe the growth and spread of cancer is the TNM classication system, where T standsfor tumor (size and how far it has spread to nearby organs), N stands for spread to lymph nodes, and M is for metastasis. Letters or numbersafter the T, N, and M provide more details about each of these factors. These 3 categories are then grouped to come up with an overall stagenumbered 0 to IV (using Roman numerals 0, I, II, III, IV). The higher the number, such as stage IV, the more serious the cancer.

StentA device placed in a body structure (such as a blood vessel or the gastrointestinal tract) to keep the structure open.

Stereotactic radiosurgeryA type of external radiation therapy that uses special equipment to position the patient and precisely give a single large dose of radiationto a tumor. It is used to treat brain tumors and other brain disorders that cannot be treated by regular surgery. Stereotactic radiosurgerymay be combined with whole-brain radiation therapy.
