Objective: We evaluated the clinicopathological findings and short- and long-term outcomes of prostate cancer (PCa) patients with bladder neck invasion who underwent cystoprostatectomy. Patients and Methods: Between 1989 and 2005, we performed 17 cystoprostatectomies for PCa patients having bladder neck invasion without distant visceral or distant lymph node metastasis. Of the 17 patients, 11 were treated with neoadjuvant hormone therapy and all patients were treated with adjuvant hormone therapy immediately after surgery. Results: All 7 patients in whom pelvic lymph node swelling was identified by preoperative imaging studies had pathological lymph node metastasis. Of the 10 patients judged as cN0 preoperatively, 7 (70.0%) had lymph node metastasis. Although local recurrence was found in 2 (11.8%) patients, no additional urinary diversion or inconvenient urinary symptoms due to PCa progression were observed in any patients. The 5-year prostate-specific antigen recurrence-free survival rate was 62.2%. Cause-specific survival at 5 years after surgery was 87.1%. The 5-year cause-specific survival rate of node-positive patients was 92.3%. Conclusion: Cystoprostatectomy followed by immediate hormone therapy may be a feasible treatment option to achieve excellent local control for patients with previously untreated PCa, even in the presence of pelvic lymph node metastasis.
