Introduction and Objectives. The reported rate of seminal vesicles invasion in RP series varies between 6-26%. Invasion of seminal vesicles by adenocarcinoma of the prostate is considered an adverse prognostic factor and consequently patients are at high risk of cancer recurrence after radical prostatectomy. The reported biochemical recurrence free rates at 5 years after RP are between 5-60% (median 30%). The aim of this paper is to assess the role of postoperative radiation in patients with seminal vesicle (SV) invasion after radical prostatectomy (RP). Materials and Methods. From a database of 500 consecutive patients who underwent RP at the University of Florida, sixty two (12%) were diagnosed with seminal vesicle invasion. All patients underwent adjuvant radiation (RT). Median age was 65 (range 48-77), median pre RP PSA was 15 ng/ml (range 4.3-91). Median pre RT PSA was 0.2 ng/ml (range 0.1 - 19 ng/ml). The PSA cut off value signifying serological failure after RP was ≥ 0.4 ng/ml. Median follow up was 56 months (range 12-104). Results. Thirty three patients (53%) relapsed serologically. Median time to PSA failure was 34 months (range 1-75). One patient (1.6%) died of metastatic prostate cancer. Pre RT PSA was the most significant prognostic factor with respect to serological failure (p=0.003). Perineural invasion (PNI) was also found as statistically significant prognostic factor (p=0.05). Pre operative PSA, pathological Gleason score, extra capsular cancer extension in addition to SV invasion (eCe) and positive surgical margins were not found to be significant prognostic factors with respect to PSA failure. Conclusions. When analyzed in the light of other reports in the literature, the present study suggests that adjuvant radiation given in pT3c patients that have undetectable PSA after RP, the PSA recurrence rate at 5 years is lower than that of patients treated with RP alone.
