Abstract

PURPOSE:

A prior report suggested that radical prostatectomy may confer a survival advantage to patients with metastatic castration recurrent prostate cancer. Therefore, a pooled analysis of 9 trials performed by Cancer and Leukemia Group B was done to determine if men with metastatic castration recurrent prostate cancer who underwent prior prostatectomy had improved clinical outcomes, such as overall, prostate specific, progression-free and PSA progression-free survival, than men who did not undergo prior prostatectomy.

MATERIALS AND METHODS:

Data from 9 multi-institutional trials performed by Cancer and Leukemia Group B were combined. Eligible patients had progressive prostate cancer during androgen deprivation therapy, Eastern Cooperative Oncology Group performance status 0-2, and adequate hematological, renal and hepatic functions. The proportional hazards model was used to assess the prognostic importance of radical prostatectomy for predicting clinical outcomes.

RESULTS:

Of 1,238 men 310 (25%) underwent prostatectomy. Median survival was 14.7 (95% CI 12.9-16.7) and 14.5 months (95% CI 13.5-15.7) in men who did and did not undergo prostatectomy, respectively. The HR for death was 1.03 (95% CI 0.90-1.19, p = 0.65) in men with vs without prostatectomy.

CONCLUSIONS:

Prior prostatectomy in men with metastatic castration recurrent prostate cancer who were subsequently enrolled on clinical trials for cancer treatment had similar survival compared to men who did not undergo prior prostatectomy. These data do not support another report suggesting that prior prostatectomy confers a subsequent survival advantage in men with castration recurrent prostate cancer.
