Overall survival (OS) and recurrence-free survival (RFS) of gastric cancer patients in the validation cohort based on MPK scores after surgery. A Overall survival. B Recurrence-free survival. In the low-risk group, the 1-, 3-, and 5-year overall survival rates were 98.1%, 84.5%, and 57.4%, with a median survival time of 70.0 months. In the moderate-risk group, the corresponding rates were 80.9%, 65.6%, and 0.0%, with a median survival time of 52.0 months. In the high-risk group, the 1-, 3-, and 5-year overall survival rates were 85.7%, 0.0%, and 0.0%, with a median survival time of 24.0 months. The overall survival rates and recurrence-free rates remained statistically significantly different among the three risk groups (P < 0.001)
