Recently developed tissue polypeptide specific antigen (TPS) and CYFRA 21-1 assays determine the soluble cytokeratin 18 and 19 fragments, respectively, in serum. The authors compared the value of TPS, CYFRA 21-1, and carcinoembryonic antigen (CEA) for the diagnosis, staging, prognosis, and monitoring of patients with nonsmall cell lung carcinoma (NSCLC).
