ITGAV protein levels, and the clinical significance of ITGAV expression in small cell lung carcinoma (SCLC). Panels A–L The protein levels of ITGAV in non-SCLC (A–F) and SCLC (G–L) tissues under the microscope by in-house tissue microarrays. The left figure of each two combined figures is 200×, and the right figure is 400×. Panel M A Kaplan–Meier curve of overall survival between high- and low-ITGAV mRNA expression groups. Panel N A Kaplan–Meier curve of disease-free survival between high- and low-ITGAV mRNA expression groups. Panel O Summary receiver operating characteristic curve for identifying SCLC based on ITGAV mRNA expression. SENS sensitivity, SPEC specificity, AUC area under the curve
