CDKN2C and lung carcinoma: Moreover, based on the 11 raw datasets with both SCLC and NSCLC samples (n = 1135), CDKN2C expression made it feasible to differentiate SCLC from NSCLC (sensitivity = 0.87, specificity = 0.94, AUC = 0.96; Fig. 3K), implying CDKN2C was a potential marker identifying the two subtypes of lung cancer.
