| Popis: | Objectives To investigate the prognostic effect of the prostate cancer (PCa) volume involving the seminal vesicles (CVSVs) in the radical prostatectomy specimen from patients with Stage pT3bpN0 PCa. Methods We retrospectively reviewed the clinical records of 27 patients with Stage pT3bpN0 PCa who had undergone radical prostatectomy alone. We measured the CVSVs using a grid method on the glass slide under microscopic inspection and investigated the association of the CVSVs with clinicopathologic variables. Results Prostate-specific antigen (PSA) failure was confirmed in 11 of the 27 patients (41%) during a median follow-up of 34 months. The 3-year PSA failure-free survival rate was 48%. The median CVSVs was 1.14 cm 3 . On univariate analysis, a CVSVs of >1.63 cm 3 was associated with positive surgical margins ( P = .018), bilateral seminal vesicle involvement ( P = .03), a long maximal tumor dimension ( P = .031), and a greater preoperative PSA level ( P = .0007). The 3-year PSA failure-free survival rate for those with a CVSVs of ≤1.63 cm 3 vs >1.63 cm 3 was 80% and 0%, respectively ( P = .0009). On multivariate analysis, only the PSA level and CVSVs were identified as significant and independent predictors of PSA failure. Stratifying patients into 3 risk groups by these predictors, the PSA failure-free survival rate for patients with a PSA level ≥10 ng/mL and a CVSVs of >1.63 cm 3 was significantly worse than for any other group. Conclusions The CVSVs is useful and invaluable as an independent predictor of PSA failure in patients with Stage pT3bpN0 PCa. The measurement of the CVSVs is simple and helped to determine the indication for adjuvant treatment after radical prostatectomy. |
