Abstract: Objective: Radical prostatectomy remains the standard treatment for early prostate cancer. Few data in the literature are from South East Asia. This study was conducted to evaluate the outcome of radical prostatectomy in Thai men. Methods: A total of 151 patients with prostate cancer underwent radical prostatectomy at Siriraj Hospital, Bangkok, between 1994 and 2003. Clinical staging, preoperative prostate-specific antigen (PSA) and Gleason score were evaluated with pathological stage and margin status. Follow-up PSA monitoring and survival were analysed. Results: Of 121 patients with clinical localized disease, 79 (65.3%), 40 (33.1%) and two (1.6%) had localized, locally advanced and metastatic disease, respectively, on pathology. The chance of localized disease with a preoperative PSA of 10 ng/mL or less, more than 10-50 ng/mL and more than 50 ng/mL was 75.5%, 50% and 12.5%, respectively (all p < 0.001). The chance of localized disease with a Gleason score of 2-4, 5-7 and 8-10 was 85%, 55.1% and 20.8%, respectively (all p < 0.02). Mean follow-up was 30 months. Among 140 evaluable patients, 51 (36.4%) had adjuvant therapy and 136 (97.1%) had undetectable PSA without clinical progression. The cumulative PSA progression-free survival among patients with pathological T1N0, T2N0 and T3N0 disease was 0.83 at 82 months, 0.48 at 85 months and 0.31 at 57 months, respectively. Conclusion: Radical prostatectomy in Thai men shows excellent results. The trend is the same as in Western series. The chance of organ-confined disease and free margin was high in patients with clinical T2 or less, PSA less than 10 ng/mL and low Gleason score. PSA progression-free survival was high in patients with organ-confined disease. © 2005 Elsevier. All rights reserved.
