KLK8 expression-based prognosis prediction model of LUSC. a Prognostic nomogram based on the clinicopathological factors, KLK8 expression, and other immune markers predicting the 1-year, 2-year, and 3-year overall survival rate in our LUSC cohort. T, T stage. N, N stage. CoExp, PD-L1, and CD47 co-expression. CD8TILs, CD8+ tumor infiltration lymphocytes. CD68 Macrophage, CD68+ infiltration macrophage. b-c Receiver Operating Characteristic (ROC) curves of the prognostic nomogram in the training set (b) and the testing set (c). d-e K-M curves showing the overall survival in LUSC TMA stratified by the prognostic nomogram in the training set (d) and the testing set (e). Blue, KLK8 low expression group. Yellow, KLK8 high expression group
