title: [Clinical results of radical surgery for prostate cancer].
abstract: We reported the clinical results of radical surgeries for 44 patients with prostate cancer performed between November 1984 and December 1992. The patients were aged from 57 to 79-year-old (mean 67.2) and classified as clinical stage A2 (6 cases), B1 (7), B2 (12), C (16) and D1 (3) respectively. Radical prostatectomy was performed in 42 cases and radical cystoprostatectomy with urinary diversion in 2 patients, and thirty-nine of 44 cases underwent endocrine or chemoendocrine therapies prior to the surgeries. In all patients with stage A2-B1, the operations were curative, on the other hand, more than 80% of clinical stage B2 patients had pT3 tumors and 33.3% of them had lymph node involvements. With regard to stage C patients, the incidence of lymph node metastasis and positive margin was more frequent. Postoperative adjuvant therapies were added to the patients with pT3,4 tumors and nodal involvements. Patients without residual tumors (n = 20) remained disease-free for 8-89 months (mean 32.8). Of 24 patients who had incomplete resection of tumors, 2 died of other diseases, other 2 were alive recurrent and 20 were alive free from disease for 3-99 months (mean 33.8). The surgical indication for low-stage (A2-B2) prostate cancer has been widely accepted, however that for high-stage cancer (C,D1) has remained controversial. It was our belief that radical surgeries for high-stage cancer could become a potentially curative therapeutic modality in combination with pre- and post-operative adjuvant therapies.
