Other Treatment
Radiation therapy
Radiation therapy for
prostate cancer may be used alone or combined with
hormone treatment. In rare cases, it is used with surgery. It is most effective
in treating cancers that have not spread beyond the prostate, but it can also
be effective in treating cancer that is only in the tissue near the prostate
(locally advanced prostate cancer). Radiation therapy also is used to relieve
pain from metastatic cancer or cancer that comes back after surgery.
Radiation therapy for locally advanced prostate cancer is often combined
with hormone treatment. Using both together improves your chances of being
disease-free for longer and living longer.6
- External-beam radiation therapy uses a large machine
to aim a beam of radiation at your tumor to destroy cancer cells. The radiation
damages the genetic material of the cells so that they can't grow. Although
radiation damages normal cells as well as cancer cells, the normal cells can
repair themselves and function, while the cancer cells cannot. If cancer has
spread to your bones, radiation treatment may be given to specific areas to
relieve pain.
Side effects
Radiation treatment commonly has
side effects, including
urinary incontinence, inflammation of the bladder and
colon (colitis), diarrhea, and erection problems.
Side effects
are common. Some men develop long-term problems that may have a significant
impact on the quality of their lives. Long-term problems that can be caused by
radiation treatment include:
- An irritated rectum and an urgent need to pass a stool. This is
called proctitis.
- An inflamed bladder and urination problems. This is called
cystitis.
- An inflamed intestine and diarrhea. This is called
enteritis.
- Being unable to have an erection. This is called
impotence.
- Being unable to control urination. This is called
incontinence.
- Painful urination. This is called dysuria.
Complementary therapy
Complementary therapies, such as
acupuncture,
herbs,
biofeedback,
meditation,
yoga, and
vitamins, are sometimes used along with medical
treatment. Some people feel that they benefit from some of these therapies.
Before you try a complementary therapy, talk to your doctor about
the possible value and potential side effects. Let your doctor know if you are
already using any such therapies. Complementary therapies are not meant to take
the place of standard medical treatment, but they may improve your quality of
life and help you deal with the stress and side effects of cancer treatment.
Clinical trials
Clinical trials are
ongoing to find ways to prevent, detect, diagnose, and treat prostate cancer.
For example, scientists are testing vaccines that use the
immune system to keep cancer from getting worse. Other
studies are testing on-and-off hormone therapy for men who have advanced
prostate cancer. Hormone therapy lasts until cancer growth stops, then begins
again when the cancer progresses. These trials hope to prove that men can avoid
some of the side effects of continuous hormone therapy and still receive
treatment that will block cancer growth.19 If you are

Cancer Institute Clinical Trials Support Unit (www.ctsu.org).
