Evaluation of prostate specific antigen as a tumor marker in cancer prostate.
The present study was undertaken to evaluate the prostate specific antigen (PSA) alongwith other diagnostic methods as an application for a screening test, tumor marker and its relation to post surgical situation. The PSA has shown a sensitivity of 73.3% and specificity of 77.2%. The predictive value for positive PSA was 57% and for negative test was 66.6%. Local standards for PSA values in Pakistani community need to be established. The PSA test, inspite of its low specificity holds good promise for its contributory role as a tumor marker in prostate cancer.
