Prognostic indicators for long term outcome following radical retropubic prostatectomy for prostate cancer involving the seminal vesicles.
Seminal vesicle involvement at the time of radical prostatectomy (RP) for prostate cancer has been equated with metastatic disease. We review our biochemical freedom from disease results following RP in patients with seminal vesicle involvement with particular attention to identifying variables that may be predictive of disease recurrence. We retrospectively reviewed our surgical database and identified patients with pT3b (2002 AJCC) prostate cancer at RP [corrected]. There were 70 cases without lymph node involvement and with available clinical follow-up identified. Any patient receiving androgen deprivation therapy, radiation therapy, or with a sustained PSA elevation greater than 0.2 ng/mL was considered a biochemical failure. Results were calculated using the Kaplan-Meier method. Mean age was 63.4 (range 45.7-79.5) years, mean preoperative PSA was 11.3 ng/mL (range 2-60), mean biopsy Gleason score was 7.2 (range 4-9), mean RP Gleason score was 7.5 (range 5-9), and median follow-up time was 61.5 months (range 2.3-160.6). Overall, 33/70 (47%) patients were without evidence of disease without further therapy. For patients with pT3bN0Mx prostate cancer, margin status, capsular invasion, and PSA were not statistically significant risk factors for disease progression. Gleason score and major Gleason grade were the only statistically significant variables that predicted disease progression. A specimen Gleason score of greater than 7 and major Gleason grades greater than 3 were associated with an increased rate of disease progression in this patient group.
