focal cryoablation
and prostate cancer
last update April 2007

Prostate cancer is the most common cancer affecting
American men. More than 230,000 men are diagnosed
every year in the United States and 30,000 die from the
disease.

Men with prostate cancer typically receive one of three
recommended therapies: surgical removal of the whole
organ, external beam radiation or brachytherapy. External
beam radiation consists of radiation directed at the
prostate from outside the body. The disadvantage for this
technique is that healthy parts of the body receive
radiation along with the cancer. According to a recent
study, external beam radiation may trigger an almost 70
percent rise in the risk for rectal cancer. While,
brachytherapy involves using implanted radioactive seed
surgery to treat the whole prostate gland. However, the
common complications of surgical removal and
brachytherapy are sexual dysfunction and urinary
incontinence.

A new non-surgical treatment for prostate cancer, which
may preserve urinary and sexual function was presented
at the Society of Interventional Radiology's 30th Annual
Scientific Meeting. This new technique is called "male
lumpectomy" - an application of focal cryoablation. In a
cryoablation procedure, the interventional radiologist
inserts a probe through the skin, using imaging to guide
the needle to the location of the tumor. The probe then
circulates extremely cold gas to freeze and destroy the
tumor. Thus, it spares the healthy tissue in and around
the prostate gland.
General anesthesia is needed for the whole procedure
and the patients usually can return to normal activities
within one to two weeks.
