We examined 4 postulates: 1) radical perineal prostatectomy provides a substantial disease control benefit in men with clinically confined prostate cancer, 2) postoperative prostate specific antigen (PSA) levels are an excellent surrogate end point for defining disease control, 3) the biology of primary malignancy defines the interval to death after recurrence and 4) the interval from intervention to death from recurrence is so long that current series of alternative curative therapies have insufficient duration of observation to permit a comparison with the results of surgery.
