In this study, quadcapture using antibodies against MUC-1, EGFR, HER2, and EpCAM resulted in the identification of CTCs in 20% of NSCLC and 80% of SCLC samples, while capture using just a singular anti-EpCAM antibody improved NSCLC capture (40%) but decreased SCLC capture (60%) rates [48]. The gene discussed is MUC1; the disease is small cell lung carcinoma.
