As shown in Table 2, familiar positive correlation between MTA1 staining and EpCAM staining was found in ADC (p < 0.05), SCC (p = 0.01), and SCLC (p = 0.01), while no correlation was found in large cell carcinoma (LCC) (p > 0.05). The gene discussed is EPCAM; the disease is small cell lung carcinoma.
