The clinical value of combined detection of seven lung cancer-related autoantibodies in assisting the diagnosis of non-small-cell lung cancer.

Evaluate the clinical value of lung-cancer-related autoantibodies (CAGE, GAGE7, GBU4-5, MAGEA1, P53, PGP9.5, SOX2) in auxiliary diagnosis of non-small-cell lung cancer (NSCLC). We detected the concentrations of above 7 antibodies and lung cancer markers (CEA, NSE, CYFRE21-1) and drew area under the receiver characteristic curve of 316 patients. The concentrations of CAGE, GBU4-5, MAGEA1, P53, PGP9.5 and SOX2 of significantly higher than other groups ( < 0.01). The sensitivity of different stages and pathological types of NSCLC consistent. Among them, the sensitivity of combined-detection in diagnosing adenocarcinoma and squamous cell carcinoma significantly better than CEA, NSE and CYFRA21-1. The combined detection has better efficacy in assisting the diagnosis of NSCLC and has certain clinical promotion and application value.
