Abstract

(Purpose) The efficacy of the reduction time (τ) after castration as a prognostic factor was examined by comparing to Gleason score.
(Materials and Methods) The change of prostatic volume after castration was observed from the castration to 3 months after in 24 cases of prostatic cancer. Prostatic volume was examined by transrectal ultrasonography of the prostate. Survival curves was calculated by Kaplan-Meier method. Differences among survival curves were analyzed using Cox-Mantel test.
(Results) τ had a close relationship to the prognosis of each case (Wilcoxon test: p<0.05, Cox-Mantel test: p<0.05). Gleason score had a weak relationship to prognosis (Wilcoxon test: N. S., Cox-Mantel test: p<0.05).
(Conclusions) τ was efficient as prognostic factor compared to Gleason score.
