title: [Clinical evaluation of a combination assay of CEA, CA-19-9 and TPA in patients with colorectal cancer].
abstract: The effectiveness of serum CEA (56 cases), CA-19-9 (53 cases) and TPA (48 cases) in patients with colorectal cancer has been evaluated. The preoperative sensitivity and specificity of CEA and CA 19-9 were found to be almost the same in level but the level of TPA was low. In 20 cases recurrent, the sensitivity of the marker was 66.7% in the liver, 60% in the lung, and 66.7% in the local recurrence of primary foci. In these recurrent cases, serum CEA in initially elevated to 65%, CA 19-9 to 25%, and TPA to only 10%. In diagnostic rate imaging or in our clinical findings, however, the frequency was almost the same as tumor markers.
