Cryosurgery Results for Prostate Cancer Treatments
Prostate
cryosurgery has been used for the clinical
management and treatment of localized prostate
cancer since the early 1990’s. Retrospective research
and studies which have followed 370 patients treated
between 1991 and 1996 at the Allegheny General
Hospital in Pittsburgh, PA recently reported the
success of the minimally invasive procedure, cryosurgery,
for prostate cancer when used as a primary treatment.
The median follow-up of this study was over 12
years and the study reports a disease-free survival
rate at 10 years of 80.56% (low risk group), 74.15%
(moderate risk group) and 45.45% (high risk group).
The 10-year negative biopsy rate was 76.96%.
Additional, research at the Crittenton
Hospital radiology department in Rochester, MI
shows the success of the minimally invasive procedure,
cryosurgery,
for prostate cancer when used as a primary treatment.
Over 350 patients were treated with primary prostate
cancer cryosurgery, with 279 patients having
cancer confined to the prostate and 77 patients
whose cancer had spread outside of the prostate,
but not to distant parts of the body. After three
years, 90% of the 279 patients with confined prostate
cancer had successful cryosurgical ablation treatment.
Of the 77 patients whose cancer had spread outside
the prostate, 74% of patients remained cancer
free. More than 86% of all prostate cryoablation
patients experienced a successful treatment.
The success rates of primary cryotherapy
ablation for prostate cancer compared to other
prostate cancer treatment options is at least
equivalent to that of conventional invasive radical
surgery and radiation treatments for treatment
of prostate cancer. Click Primary

ablation in prostate cancer treatment.
Salvage Cryotherapy Ablation Treatment Results
Research at MD Anderson Cancer Center suggests a high survival rate for prostate cancer recurrence patients treated with cryotherapy ablation. One hundred and thirty-one men were analyzed after their salvage cryosurgical treatments between 1992 and 1995. The patients were followed for approximately five-years. Their overall survival rate was 73%. The success rates for salvage cryoablation prostate cancer treatments are more positive than salvage prostatectomy with lower rectal injury and incontinence side effects.

Nerve Sparing (Focal) Cryosurgery:
A New Treatment For Prostate Cancer
Initial research shows promising success for nerve
sparing (focal) cryosurgery in prostate cancer
treatments. Today, urologists are referring to
a concept called “male lumpectomy,” which derives
its name from the surgical procedure to remove
a cancerous tumor from a woman’s breast. A lumpectomy
allows for the tumor to be removed without causing
extreme physical or cosmetic damage. The male
lumpectomy is expected to have a similar effect
for the male prostate. The current peer-reviewed
literature on focal
cryoablation of localized prostate cancer
a few papers with evidence from single institutions
patient series; no multi-center or prospective
randomized trials have been published as of December
2007. These reports contain a total of 65 men
treated with focal
ablation with a mean follow-up ranging from
28-70 months. Based on these series, the optimal
definition of treatment success is presently undetermined
and success is best defined by follow-up prostate
biopsy. A total of 38 out of the overall 65 men
have received a post cryoablation prostate biopsy
where only 4 of the 38 men had residual cancer
identified. The related side effects appear to
be reduced when undergoing nerve
sparing (focal) cryoablation relative to those
side effected reported in the earlier whole gland
treatment approaches. There have been no reported
cases of urinary incontinence, rectal injury,
urethral stricture or urethral sloughing. The
side effect of impotence is also lowered when
nerve-sparing (focal) cryotherapy is used as treatment.
These reports indicate that 71 – 89% of men treated
have preserved their potency. See Nerve
Sparing (Focal) Cryotherapy to learn more
about this prostate cancer treatment option.
