About Prostate Cancer The prostate is a walnut-‐shaped organ in a man’s lower abdomen that controls the flow of urine and semen through the penis. Prostate cancer is among the leading causes of cancer death among American men, second only to lung cancer. Risk factors: There is no single cause of prostate cancer, though there are several known risk factors: •  Age – Risks generally increase for older men. •  Race – African-‐American men have a higher risk

for unknown reasons. •  Na6onality – Asian men, for example, have a

lower risk. •  Diet – Red meat and dairy products tend to

increase risk. •  Lack of exercise •  Family history of prostate cancer


•  Early-‐stage prostate cancer usually has no symptoms. Older men may experience frequent urinaGon, though it’s likely due to an enlarged prostate in a condiGon known as benign prostaGc hypertrophy, or BPH. Pain or bleeding is not commonly associated with early stages.

•  Prostate cancer is suspected if men have an elevated level of a substance in the bloodstream known

as prostate specific anGgen (PSA), or if they have an abnormality like a nodule found during a digital rectal examinaGon. A prostate cancer diagnosis is confirmed, however, only through biopsy.

•  Urologists usually perform biopsies as an outpaGent procedure. An ultrasound probe is used to guide

a needle that removes 10 to 12 small Gssue samples from different parts of the prostate gland. SomeGmes, addiGonal diagnosGc tests like a bone scan, CT or MRI are performed, depending on the specific diagnosis.

How does CyberKnife treat prostate cancer?

Prior to stereotacGc body radiosurgery treatment with CyberKnife, small Gssue markers known as fiducials are implanted in the prostate to help the CyberKnife pinpoint the tumor locaGon throughout each treatment, so the radiaGon beams can be locked on the tumor. About a week later, paGents are fiWed with a custom body mold of soX material that they lie on during treatments. The fiYng process is painless. The treatment process includes: I.  ConsultaGon appointment II.  Pretreatment procedures III.  CyberKnife treatment IV.  Follow-‐up

Consulta6on and Pretreatment Procedures CyberKnife Center of Chicago physicians, therapists and nurses are focused on your individualized treatment plan: •  You will meet a CyberKnife Center of Chicago radiaGon oncologist to decide if

CyberKnife treatment is appropriate for your diagnosis. •  Your CyberKnife team will decide which pretreatment procedures you may need to

help develop your treatment plan. These could include a CT scan, an MRI, laboratory studies or Gssue markers.

•  The data from your pretreatment procedures will be used by the CyberKnife team to

determine the exact size, shape and locaGon of your tumor.

•  This informaGon will indicate the size of the area being treated with radiaGon, the radiaGon dose and criGcal structures where radiaGon exposure should be minimized.


CyberKnife Treatment Typically treatment is completed within five sessions. On the day of your treatment: 1.  A therapist will help you onto the treatment

table and fit the body mold. PaGents are observed throughout the treatment on closed-‐circuit television, and they can pause treatment at any Gme by waving or speaking to the technicians.

2.  While the CyberKnife’s advanced tracking system accounts for movements like breathing, you’re asked to lie sGll during treatments. The system periodically takes x-‐ray images and compares them to the CT scan data to make sure the radiaGon beam is locked on the tumor.

3.  PaGents can usually return to their normal rouGnes once the treatment is complete.

FOR YOUR INFORMATION •  Treatment procedures take about 30 – 90

minutes, depending on the complexity of your tumor.

•  PaGents are asked to wear comfortable clothing during CyberKnife treatments. Jewelry is acceptable unless it is close to the area being treated.

•  Feel free to bring an iPod® or your favorite music CDs with you on the day of your treatment, and we will play them for you during the procedure.
