Abstract:
Objective To study the incidence rate of prostate cancer detected in the specimen of radial cystoprostatectomy for bladder cancer and to evaluate its effect on the prognosis.Methods From June 2012 to June 2017,the clinical data of 132 patients with bladder cancer undergoing radical cystectomy (RCP) were analyzed retrospectively.The average age of 132 patients with bladder cancer was 61.2 years (37-89 years old).The serum of PSA of 89 cases out of 132 patients was examined before operation,21 cases 4 ng/ml ＜ tPSA ＜ 10 ng/ml,1 case tPSA 17 ng/ml and 67 cases tPSA ＜ 4 ng/ml.The pathology of bladder and prostate,the location and range of prostate cancer and Gleason score and the prognostic effect of prostate cancer was evaluated.Results The 132 patients with bladder cancer,116 cases (87.9％) were high grade urothelial carcinoma,8 cases (6.0％) were bladder carcinoma in situ,6 cases (4.5％) were low grade urothelial carcinoma,1 case was neuroendocrine bladder carcinoma and 1 case was signet ring cell carcinoma.The 21 cases of prostate cancer were combined with Gleason score,among which 3 + 2 score in 1 cases,3 +3 score in 17 cases,4 +3 and 3 +4 in 1 cases,and 4 +5 score in 1 cases.The lesions were unilateral in 14 cases and bilateral in 7 cases.The lesions were ＜0.5 ml in 3 cases,0.5-0.7 ml in 14 cases and 0.7-1.0 ml in 4 cases.The average age of 21 cases with prostate cancer was 67.5 years old (41-89 years).Of the 21 cases of prostate cancer,the serum tPSA was abnormal in 4 cases with an average of 8.8 ng/ml (4.2-17.0 ng/ml),the serum tPSA was normal in 12 cases with an average of 2.5 ng/ml (1.3-3.7 ng/ml),and the serum PSA in 5 cases was not detected before operation.Three cases of prostate cancer aged less than 60 years old with the detection rate of 9.6％ (3/31);18 cases were equal or older than 60 years old with the detection rate of 17.8％ (18/101).Multi parameter analysis showed that the incidence of prostate cancer increased with the age of the patients (OR =1.36,P =0.048).Followed up for 5 to 51 months,no PSA relapse was found and no patient receiving related treatment.Conclusions The detection rate of prostate cancer is very high in the specimen of radial cystoprostatectomy for bladder cancer.The clinical manifestation of the prostatic involvement is concealed.Radical resection of the prostate is necessary in radical resection of bladder cancer.
