COMPARATIVE SENSITIVITY OF URINARY CYFRA 21-1, URINARY BLADDER CANCER ANTIGEN, TISSUE POLYPEPTIDE ANTIGEN AND NMP22 TO DETECT BLADDER CANCER

Abstract

Our preliminary evaluation showed the tests to be potential noninvasive adjuncts to help determine the need for cystoscopy. The combination of 2 tumor markers, NMP22 and 1 cytokeratin (CYFRA 21-1 or urinary bladder cancer antigen), seemed to be the most effective. Further comparative studies are needed to assess the promising diagnostic role of these markers.
