The clinical significance of anti-mitotic spindle apparatus antibody (MSA) and anti-centromere antibody (ACA) detected in patients with small cell lung cancer (SCLC).

Purpose: The project is aimed to detect anti-mitotic spindle apparatus antibody (MSA) and anti-centromere antibody (ACA) and explore the clinical value for the diagnosis of small cell lung cancer (SCLC), providing clinical evidence for molecular studies of SCLC.

Methods: 93 SCLC patients, 208 patients with other cancers and 50 healthy controls were enrolled in this study. MSA antibodies were detected by enzyme linked immunosorbent assay (ELISA).
