Introduction:
The aim of this study is to present the oncologic outcomes and to determine prognostic parameters of overall (OS), cancer specific survival (CSS), disease progression free survival (DPFS) and biochemical progression free survival (BPFS) after surgery for pT3a prostate cancer (PCa).
Material And Methods:
Between 2002 and 2007, a pT3a stage after radical prostatectomy was detected in 126 patients at our institution. Kaplan-Meier analysis was used to calculate OS, CSS, DPFS and BPFS. Cox regression was used to identify predictive factors of survival.
Results:
Five-year OS, CSS, DPFS and BPFS rates were 96%, 98.7%, 97.3% and 60%, respectively. Among patients with prostate specific antigen (PSA) <10 ng/ml and PSA >20 ng/ml the 5-year OS was 98.8% and 80%, respectively, whereas 5-year BPFS was 66% and 16.6%, respectively. Survival was different when comparing surgery Gleason score ≤7 and ≥8. 5-year OS and BPFS were 98% vs. 80%, and 62.6% vs. 27.3%, respectively. Specimen Gleason score and preoperative PSA were significant predictors of BPFS. The risk of biochemical progression increased up to 2-fold when a Gleason score ≥8 was present at final pathology.
Conclusions:
In locally advanced pT3 PCa, surgery can yield very good cancer control and survival rates especially in cases with PSA <10 ng/ml and Gleason score ≤7. PSA and Gleason score after surgery are the most significant predictors of outcomes after radical prostatectomy.
