Histopathological outcome in 167 patients operated on with radical retropubic prostatectomy.

Abstract

OBJECTIVE To evaluate the histopathological outcome in patients with prostate cancer operated on with radical retropubic prostatectomy. MATERIAL AND METHODS A total of 167 patients with clinically organ-localized prostate cancer treated with open radical retropubic prostatectomy between 1996 and 2001 were divided into three equally sized consecutive cohorts (cohorts I-III). The prostatectomy specimens were re-examined by two pathologists with respect to pathological tumour stage, tumour grade and surgical tumour margins. RESULTS The mean preoperative prostate-specific antigen (PSA) value was statistically significantly higher in cohort I compared to cohorts II and III: 13.2, 9.0 and 8.5 ng/ml, respectively (p<0.05). The incidence of locally advanced (pT3a-3b) tumours was 44% in cohort I and 20% in both cohorts II and III (p<0.05). The incidence of positive tumour margins was 58% in cohort I, compared to 30% in cohort II and 13% in cohort III (p<0.05). The incidence of positive intracapsular tumour margins was 55% in cohort I, compared to 25% in cohort II and 8.9% in cohort III (p<0.05). The incidence of positive tumour margins in the pT2 tumours in cohorts I-III was 57%, 26% and 8.9%, respectively (p<0.05). Cohort III had significantly more low-grade tumours (Gleason score 4-6; 58.9%) compared to cohorts I (31.5%) and II (34%). There was a higher incidence of Gleason score >or=7 in the pT3 tumours compared to the pT2 tumours (80% vs 46%) and in margin-positive compared to -negative tumours (69.6% vs 48.6%) (p<0.05). CONCLUSIONS The decline in pT3 tumours and positive tumour margins between cohorts I-III is probably due to a gradually more strict selection of patients for radical retropubic prostatectomy. The successive reduction in positive intracapsular tumour margins is most likely due to an improved surgical technique.
