Objectives. To determine whether subcapsular orchiectomy provides subo
ptimal treatment of metastatic prostate cancer when used to avoid the
psychologic consequences of the empty scrotum that results from total
orchiectomy. Methods. We compared testosterone and prostate-specific a
ntigen levels and survival of 37 patients who underwent total orchiect
omy and 37 patients who underwent subcapsular orchiectomy for metastat
ic prostate cancer. Results. The two groups of 57 patients were simila
r by clinical parameters. Postoperatively, testosterone levels were 21
+/- 11 ng/dL for subcapsular versus 21 +/- 9 ng/dL for total orchiect
omy patients, Tumor response was similar in the two groups when assess
ed by prostate-specific antigen measured 3 weeks, 6 months, and 1, 2,
and 3 years postoperatively, Survival was similar when assessed using
Kaplan-Meier analysis (P = 0.76). Conclusions, Subcapsular orchiectomy
is a viable option for treatment of metastatic prostate cancer.
