Abstract
PSA is emerging as the best marker in oncology and had a profound impact on all aspects of prostate cancer care. From clinically suspected prostate tumor, 395 serum samples were taken out and estimated for serum PSA. Among elevated serum PSA, 98 were correlated with histologic findings. 42(42.8%) cases were BHP among 98 cases and 78.7% had serum PSA level within 10 ng/ml. 5 patients (5.1%) had PIN histologically, 3(60%) of which had PSA level upto 10 ng/ml and 2(40%) had serum PSA upto 20 ng/ml. 51(52%) were adenocarcinoma prostate of different grades and PSA level varies from less than 10 ng/ml to more than 50 ng/ml which almost correlates with the tumor grades.
