A STUDY TO CORRELATE HISTOPATHOLOGY, SERUM PSA LEVEL AND IMMUNOHISTOCHEMICAL EXPRESSION OF ER & PR IN PROSTATIC GROWTH

Objectives- Prostate is a bromusculoglandular structure situated at the neck of urinary bladder. It enlarges due to benign hyperplasia of prostate (BHP), prostatic intraepithelial neoplasia (PIN) or adenocarcinoma. Enlargement of prostate is associated with raised serum level of prostate-specic antigen (PSA) and altered expression of estrogen receptor (ER) and progesterone receptor (PR). The aim of our study is to correlate the histopathology, PSA levels and altered expression of ER and PR by immunohistochemistry in different prostatic growth lesions. Methodology- Patients diagnosed as having prostatic growth were enrolled and their serum PSA levels were noted. Histopathological examination and immunohistochemical analysis of prostatic tissues for ER and PR were carried out to nd out correlation of different type of growth with serum PSA level and expression of ER and PR. Results- A total 96 cases studied of them 61(63.54%) patients presented with BHP, 20(20.83%) patients with BHP with chronic prostatitis, 3 patients presented with metaplastic changes, 5 cases with of PIN and 6 patients presented with adenocarcinoma with different Gleason score. PR expression positivity in epithelial cells and stromal cells of BHP cases were 51(83.6%) and 53(86.88%) respectively. Patients presented with adenocarcinoma showed only 33.33 %( 2cases) positivity in epithelial cells and 50% (3cases) positivity in stromal cells. Serum PSA level were signicantly higher in adenocarcinoma patients as compare to BHP patients. Conclusion- By observing these ndings it can be suggested that and antiprogesterone therapy may be helpful in the treatment of prostatic adenocarcinoma.
