ABSTRACT
Objective To compare epididymis-sparing orchiectomy (group A) with traditional orchiectomy (group B ) in patients with advanced prostate cancer,and to evaluate which procedure is better.Methods A total of 60 cases of advanced prostate cancer patients were enrolled,with 30 cases in group A and 30 cases in group B.They were given oral anti-androgen from 1 day after castration.Serum level of testosterone and prostatic specific antigen (PSA) was detected before castration,and 1 week,1,3,6,9 and 12 months after castration.Patient satisfaction was also evaluated.Results On time point of 12 months after castration,the average level of serum testosterone was 0.2 nmol/L (95 ％ confidence interval,0.1 ～ 0.9 nmol/L) in group A and 0.3 nmol/L (95％ confidence interval,0.2 ～ 0.9 nmol/L) in group B (P ＞0.05 ) ; the average value of PSA was 0.22 ng/ml in group A and 0.27 ng/ml in group B (P ＞0.05 ) ; patient satisfaction rate was 96.7％ (29/30) in group A and 53.3％ (16/30) in group B.Conclusions No significant difference of testosterone level and PSA is found between the 2 groups.However,epididymis-sparing orchiectomy meets the psychological needs better because it helps to maintain the appearance of the scrotum through epididymis preservation and epididymoplasty.
