Serum markers CASA, CEA, CYFRA 21-1, MSA, NSE, TPA and TPS in lung cancer

Abstract

Serum CASA, CEA, CYFRA 21-1, NSE, MSA, TPA, and TPS were determined in patients with lung cancer (LC), benign lung disease (BL), and healthy control (HC) donors. Using predefined cutpoints, the cytokeratin-related markers TPA, TPS, and CYFRA showed the highest sensitivity in non-small cell lung cancer (TPA; 69%, TPS 63%, CYFRA 54%), while NSE gave the highest sensitivity in small cell lung cancer (50%), indicating that these markers may be most appropriate in monitoring the course of disease and the patients response to therapy. Receiver-operator analysis was performed to compare assays at the same specificity. At high specificities (295%), CYFRA was significantly better than all assays exce..
