Objective To analyze the factors that influence the disease-free survival time after radical prostatectomy for prostate adenocarcinoma and to study the expression and significance of Bcl-2,C-erbB-2,Ki-67 in prostate adenocarcinoma. Methods A total of 51 cases of prostate adenocarcinoma undergoing radical prostatectomy were reviewed.Cox proportional hazard model was used to investigate the impact and co-impacts of the factors,which included age, preoperative PSA level,Gleason scores of biopsies and operative specimens,EPE,MR,SVI,LN,PAT,PRT and having testes or not during follow-up.Immunohistochemical staining was used in biopsies and resected specimens to evaluate the positivity of Bcl-2,C-erbB-2,Ki-67 in 15 of the 51 cases. Results In stepwise Cox proportional hazards model, the prognostic factors for recurrence were age(P=0.011),maximal androgen blockade(P=0.017), positive margin of resection(P=0.000),postoperative Gleason score(P=0.002),having testes or not after operation(P=0.040).The expressions of 3 types of proteins showed negative correlation with the prognosis of prostate carcinoma. Conclusions Among clinicopathologic factors,positive resected margin is the most powerful prognostic factor.Patients will benefit from maximal androgen blockage before radical prostatectomy.Disease-free survival after radical prostatectomy is not influenced by not having pelvic lymphadenectomy after finding no enlarged lymph nodes intraoperatively.Not preserving testes after prostatectomy is a favorable factor.The prognosis of prostate carcinoma can be predicted with the expressions of Bcl-2,C-erbB-2 and Ki-67 in biopsies or resected specimens.
