PURPOSE
The efficacy of the reduction time (tau) 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
tau 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
tau was efficient as prognostic factor compared to Gleason score.
