[Clinical study of total prostatectomy for prostatic cancer]

Total retropubic prostatectomy was performed on 31 patients with prostatic cancer (median age; 70 years). The accuracy of staging was 55% (17 patients). In 11 patients (35%) the staging had been underestimated, and in 3 patients (10%) overestimated. The pathological stage and grade were stage B in 14 patients, stage C in 4 patients, stage D1 in 13 patients (pN1; 8 patients, pN2; 5 patients), well differentiated adenocarcinoma (WDA) in 8 patients moderately differentiated adenocarcinoma (MDA) in 7 patients, and poorly differentiated adenocarcinoma (PDA) in 16 patients. The WDA were all stage B, and 85% of the PDA were stage D1. The positive surgical margin rate was 21% in stage B, 50% in stage C, 85% in stage D1, 13% in WDA, 43% in MDA, and 75% in PDA. Five of the patients died, and the causes of death were prostatic cancer in 2 patients (pN2/PDA), and others in 3 patients (1 patient; stage B/PDA, 2 patients; pN2/PDA). The 5-year survival rate (Kaplan-Meier) was 84% on the whole, 83% for stage B, 100% for stage C, 83% for stage D1, 100% for WDA, 100% for MDA, 71% for PDA, 86% for pN0, 100% for pN1, and 38% for pN2.
