The Analysis of Clinical Pathology and Immunohistochemical Staining in the Prostate Biopsies:a Report of 153 Cases

Objective To improve the accuracy of the clinical and pathological diagnosis in prostate carcinoma by analysing clinical date,pathomorphology and immunohistochemical staining of biopsy specimen acquired by prostate paracentesis through rectum.Methods retrospectively analysed the clinical and pathological date of 153patients in our hospital from January 2006 to June 2011,and investigated the information about PSA and pathology.Finally,50 patients with prostate carcinoma and 103cases of benign prostate lesions were analyzed contrastively in these patients.Result In the 50 cases with prostate carcinoma,the serum PSA mean of patients was(84.54±132.99)ng/ml,the immunohistochemistry showed PSA positive rate was 96%.P504s positive rate was 94%,CK34βE12and P63positive rate was 33.3% and 20.4%.103 cases of benign prostate disease,96 cases of these patients were diagnosed benign prostatic hyperplasia,the serum PSA mean of them was(84.54±32.99)ng/ml.The immunohistochemistry showed that: PSA positive rate was 100%,CK34βE12and P63positive rate was 99% and 98.9%,P504sfocal weak positive rate of 1%.Other seven cases were diagnosed prostatic intraepithelial neoplasia(PIN),the serum PSA mean of patients was(20.314±10.10)ng/ml,the immunohistochemistry showed PSA positive rate was 100%,CK34βE12and P63positive rate was 85.7% and 85.7%,P504spositive rate was 42.9%.Conclusion Combined with clinical date,pathomorphology change and immunohistochemical index,the accuracy rate of diagnosis and differential diagnosis in prostate carcinoma was improved remarkably.
