title: A comparison of androgen deprivation therapy versus surgical castration for patients with advanced prostatic carcinoma.
abstract: OBJECTIVE
  To examine the outcomes of patients with advanced prostate carcinoma who underwent medical or surgical castration.
  
  
  METHODS
  A hundred twenty one consecutive cases of patients with advanced prostate carcinoma who underwent medical or surgical castration between 2001 and 2006 were retrospectively reviewed. Associations between clinical outcomes and prognostic scoring factors were determined based on the Reijke study. In the surgical and medical castration groups, the impact on the prostate-specific antigen (PSA) normalization rate, the rebound rate and the disease-free survival rate were evaluated. The mean follow-up was 36.1 months.
  
  
  RESULTS
  In the initial 12 months, there were no statistical differences in the PSA normalization rate and the PSA rebound rate between the two groups. However, the PSA rebound rate after the 12th month (20.90% vs 40.74%, P=0.0175) and the 18th month PSA normalization rate (59.70% vs 37.04%, P=0.0217) differed significantly between the two groups, and these differences were maintained to the end of the study. When comparing patients grouped according to Reijke prognosis scores, there was no difference between medical and surgical castration for the good prognosis group. However, among the patients given a poor prognosis, surgical castration was superior in terms of the PSA normalization rate, the PSA rebound rate, the tumor progression-free survival rate (P<0.001) and the overall survival rate (P<0.001).
  
  
  CONCLUSIONS
  Advanced prostate carcinoma patients with poor pretreatment prognosis scores should undergo surgical castration rather than medical castration for better PSA rebound rates and overall survival.
