Efficacy of eight serially measured markers for diagnosis of prostatic carcinoma.

In this study we measured eight different tumor markers (PSA, PAP, TPA, CEA, Ca 50, Ca 19-9, Ca 125 and Ca 15-3) in 39 patients with prostatic adenocarcinoma and in 90 patients with benign prostatic hyperplasia. We then calculated the sensitivity and specificity for each tumor marker separately and found that only PSA, when we consider as normal value 10 ng/ml, has a sufficiently high sensitivity and specificity. Our conclusion is that only PSA can be used for diagnostic purposes in conjunction with other diagnostic modalities.
