Remains a mystery› Could be:

Environment Lifestyle Occupation Genetic and ethnic factors

› Age- and sex-related differences

Benign tumors -usually require no treatment Lipomas -fatty tumors -surgical removal is recommended Keloids -abnormal growth of scar tissue Angiomas -birthmarks Verruca -warts Nevi -moles

Three most common skin cancers- -Basal cell carcinoma -Squamous cell carcinoma -Malignant melanoma

Exposure to sun leading cause Skin damage from the sun is cumulative Most long-term skin damage occurs

during childhood. It takes 10-20 years before unprotected

sunbathing results in skin cancer

-Most frequent type of skin cancer. -Prolonged sun exposure -Metastasis is rare. - Extends into the dermis and may form

an ulcer -Face and upper torso -Surgical removal cures this type of

cancer 40% - 50%

Characteristics› -waxy border› -papule, with a red central crater› -rarely metastasizes

-Curettage and desiccation -Surgical excision -Radiation therapy -Cryosurgery -Mohs micrographic surgery

-nodular lesion in the epidermis. -sun, gamma rays, and x-rays -second most common cancer in caucasians -head, neck, lower lip and areas of chronic irritation or injury -extends into the dermis and lymph nodes - metastasizes and can cause death -treatment -removal of the lesion or chemosurgery

-firm, red nodule -flat lesion with a scaly crust -new ulceration or raised area on a pre- existing scar or ulcer -face, lower lip, neck, hands or arms -ulcer/flat, white patch inside the mouth -red, raised patch/ulcerated sore in anus/genitals

Freezing Simple excision Laser therapy Mohs surgery Radiation therapy Chemotherapy

-Most serious skin cancer.--Begins in a mole. -irregular shape -larger than 6mm -inconsistent color -metastasizes to every organ in the body -blood and lymphatic system-Treatment—no cure-Prevention -limiting sun-exposure - use of sunscreen

Surgical removal Chemotherapy Radiation therapy immunotherapy

-Mycosis Fungoides -involving both skin and multiple organs. -early stages - resembles psoriasis/seborrheic dermatitis -fatal

Mycosis Fungoides

SUBJECTIVE: -health history related to skin cancer. -population at greatest risk -fair complexions -blue eyes -red or blond hair -freckles.OBJECTIVE DATA: -inspect lesions -location, color, and appearance

-Biopsy of suspicious lesions -Inspection for any other lesions -Monitor any suspicious lesions for changes

-depends on the level of invasion. -wide, surgical excision of the primary lesion with a margin of normal skin. -Skin grafts

-Follow-up treatments (depends on the stage of the disease) -chemo-immunotherapy -radiation -immunotherapy -chemotherapy -gene therap.

Pain, related to lesion Anxiety, related to cancer, its

treatment, and prognosis

-Explaining procedures/diagnostic tests in terms that the pt. can understand. -Listen/accept expressions of

anger, sadness, and helplessness. -Assess pain. -Provide comfort measures -back rubs, foot massages

-detailed discharge instructions -wound care -medications -cleansing of wounds, lesions -follow-up care -assess the pt.’s and family’s knowledge -seriousness/treatment of the disease -regular physical exams/skin self-exams. -asepsis -prevent a secondary infection -protecting the skin from the sun -use of sunscreen

-Depends on the thickness of the lesion. -less than 0.76 mm thick has a survival rate of almost 100%. -3 mm thick or thicker has a survival rate of less than 50%. -Spreads to regional lymph nodes -50%, 5-year survival rate. -Metastasis -treatment is pallative -condition is terminal

Anorexia Increased metabolism Negative nitrogen balance Nausea, vomiting Diarrhea Mouth problems

Calories Protein Vitamins, minerals Fluids Enteral feedings Parenteral feedings

What is the: -aggressiveness of the cancer? -potential for spreading? -potential hazards of the therapy itself? -established success rate of the therapy?

Divided into two groups1. Cell cycle nonspecific (CCNS)2. Cell cycle specific (CCS)

CCNS effective against slow-growing cancer cells

CCS effective against fast-growing cancer cells

Alkylating agents –cause abnormal chemical bonding between adjacent DNA molecules

Antimetabolites –interfere with various metabolic actions of the cell -result in the cell’s destruction

Miotic inhibitors -interferes with cell division or mitosis

Antibiotics –should not be confused with the antibiotics one takes for an infection. -interfers with one or more stages of

RNA or DNA synthesis, or both

Hormones – -selectively suppresses the growth of certain tissues of the body Corticosteroids -used to decrease inflammatory processes caused by cancer or therapies Radioactive drugs -destroys some or all of the tissue in which the drug is localized

Biological/Response Modifiers – -targets/enhances the immune system -destroys/interferes with the

cellular activity of the tumor

Miscellaneous Agents

Combination therapy -Single chemotherapeutic agent is very rare or effective in treating cancer. -different toxicities -different mechanisms of action -act on different times in the cell division cycle -individually active against the specific cancer -more pronounced beneficial effects when used in combination vs alone

Adjuvant Agents -Rescue drugs -given with chemotherapy -prevents side effects _Mesnex -prevents hemorrhaging of the bladder _Leucovorin -interferes with folic acid metabolism -causes elevated uric acid

Affect all cells, both healthy and sick Dose-limiting effects

› Hair falls out› Cells in the gastrointestinal tract

die› Nausea and vomiting occur;

emetic potential› Myleosuppression

Nadir: lowest point for the bone marrow cells

Common› Fever, chills, headache, nausea,

and vomiting Serious

› Bronchospasm, dyspnea, and hypotension

During administration of the antineoplastic:

› -provide significant hydration to› prevent nephrotoxicity› -provide periodic monitoring of

heart and lung function

True or False: Antineoplastic drugs are used to

cure, control, or provide palliative therapy for patients with cancer.

True or False: Alkylating agents interfere with the

process of cell division of malignant cells and have no effect on the normal cells

True or False: Antineoplastic drugs may be given

alone or in combination with other antineoplastic drugs.

True or False: Antineoplastic drugs can be given only

by the intravenous route

True or False: Cisplatin cannot be administered

with needles containing aluminum because the cisplatin reacts with the aluminum, causing a precipitate formation and loss of potency.

True or False: Alopecia most often occurs 30 – 45

days after the chemotherapy treatment cycle is completed.

True or False: Immediately before

administration of the first dose of antineoplastic drug, the vital signs are taken.

True or False: The patient taking oral

chemotherapy is instructed to contact the primary health care providers if any problems occur, no matter how minor.

Alopecia - loss of hair. -Causes: -aging -drugs (anti-neoplastic agents) -anxiety -disease processes -usually not permanent, unless from aging -hair grows back, but can take several months -devastating to a person’s self-esteem and self- image

-excessive growth of hair in a masculine distribution -hereditary or acquired -treatment -dermabrasion -electrolysis -chemical depilation -shaving - plucking or rubbing with pumice -If the specific cause is treated, additional hair growth will stop

Absence or decrease in hair growth Causes: -skin disease -endocrine problems -malnutrition Treatment: -identifying and removing the cause

Disorder of the nails -soft or brittle -shape can change as the soft tissue grows -ingrown toenails Infection - nails become painful, loose and separate from the tissue Treatment: -wet dressings -topical antibiotics -surgical excision of the infected area
