Abstract
Serum prostate specific antigen (PSA) has been used as an accurate means of detecting and monitoring prostate cancer. An analysis of PSA levels, digital rectal examination and bone scan findings was carried out in a group of patients with a view to determine whether PSA can accurately predict bone metastases in carcinoma prostate and its correlation with digital examination and bone metastasis status. In 32 case series, 30 cases on followed-up after treatment of the primary, 2 of total 32 cases received hormonal therapy. one out of three with normal PSA had bone metastases. In 25 cases with positive bone scans, 23 had elevated PSA levels (mean 79.9 ng /ml). In an untreated patient with elevated PSA, a bone scan may be required to exclude bone metastases, whereas during follow-up after treatment, a normal PSA level may obviate a “routine” bone scan.
Keywords: Serum prostate specific antigen (PSA), adenocarcinoma prostate, bone scintigraphy, hormonal therapy, metastases.
