Long-term results of radical retropubic prostatectomy in men with high grade carcinoma of prostate

Purpose: We sought to determine the efficacy of radical retropubic prostatectomy in men with high grade adenocarcinoma of the prostate in a population that had not been screened for prostate specific antigen (PSA). Materials and Methods: An inception cohort of 116 men surgically treated for prostate cancer between 1980 and 1991 was created in April 1992 and prospectively followed thereafter. Median followup was 7 years (range 2.2 to 14.6). Results: The major cause of death in this group of men was prostate cancer, not competing causes. Ten-year disease specific survival was 96% for organ confined (stage pT2c or less) and 78% for unconfined (stage pT3a or greater) disease. Five and 10-year PSA progression-free survival by pathological stage was 83 and 53% for organ confined disease, and 34 and 22% for unconfined disease with negative pelvic lymph node dissection (p = 0.001). Five and 10-year metastasis-free survival was 96% for organ confined disease, and 81 and 62% for unconfined disease (p = 0.011), Men with pelvic lymph node metastasis had 70 and 30% 5 and 10-year metastasis-free survival, and 75 and 55% disease specific survival, respectively. PSA progression-free survival was 33% at 5 years. A significantly decreased risk of PSA progression was observed in men with unconfined carcinoma who received adjuvant external beam radiotherapy. Conclusions: In men with high grade prostate cancer the major cause of death was prostate cancer, not competing causes. Pathologically confined carcinoma had a significantly decreased rate of metastatic progression, These observations support the bias that early detection in these men at high risk for cause specific death may favorably impact survival.
