After adjusting for clinicopathological factors including tumor grade, tumor size, tumor depth, anatomical location, and performance status, LCP1 expression remained an independent prognostic factor for OS and LRFS in the multivariable Cox regression analysis (Supplementary Table S5) [OS: Hazard Ratio (HR) = 0.39; 95% confidence interval (CI) = 0.17–0.91; P = 0.029; LRFS: HR, 0.21; 95% CI, 0.06–0.77; P = 0.019]. Here, LCP1 is linked to neoplasm.
