Radical perineal prostatectomy for clinical stage B2 carcinoma of the prostate

Abstract

To refine the criteria for radical surgery in clinical stage B2 prostatic cancer a retrospective study was made of 53 patients who underwent radical perineal prostatectomy between 1951 and 1963. The 15-year survival free of tumor was 25 per cent, significantly less than the 51 per cent survival rate in a series of patients with clinical B1 disease undergoing radical perineal prostatectomy during the same period. Sixty-six per cent of the patients had extraprostatic extension of tumor on histological examination. The 15-year survival free of tumor in these patients was only 13 per cent, whereas those patients with tumor histologically confined to the prostate had a 15-year survival rate of 50 per cent, equal to an age-matched control population. Thus, although prolonged survival was demonstrated in patients without extraprostatic extension only a third of all clinical B2 cases were in this favorable category. Consequently, until improved reliable techniques for detection of extraprostatic extension become available it seems unwise to recommend radical prostatectomy as the treatment of choice for all men with clinical stage B2 disease.
