Kaplan-Meier survival curve and log-rank test analysis showing the association between PTK6 expression and NPC patient survival. (A) The five-year overall survival (OS) rate was 53.9% of 178 NPC patient; (B) High PTK6 expression level was significantly correlated to OS (P<0.001) in all NPC patients. (C) Cases were stratified by clinical stage. No significant difference in five-year OS rate was found between PTK6 high-expression and low-expression in NPC patients at early stages (StageI+II); (D) High PTK6 expression level was significantly associated with OS (P<0.001) in NPC patients at late stages (Stage III+IV).
