Overall survival (OS) and recurrence-free survival (RFS) of gastric cancer patients in the training 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 100.0%, 80.7%, and 56.3%, with a median survival time of 64.0 months. For recurrence-free survival, 95.5%, 68.8%, and 40.1% of patients in the low-risk group survived recurrence-free at 1, 3, and 5 years, with a median time to recurrence of 54.0 months. In the moderate-risk group, the 1-, 3-, and 5-year overall survival rates were 98.1%, 56.2%, and 33.9%, with a median survival time of 44.0 months. The corresponding recurrence-free survival rates were 93.2%, 48.7%, and 24.0%, with a median time to recurrence of 35.0 months. In the high-risk group, the 1-, 3-, and 5-year overall survival rates were 78.6%, 0.0%, and 0.0%, with a median survival time of 23 months. The recurrence-free survival rates in this group were 66.7%, 0.0%, and 0.0%, with a median time to recurrence of 16.0 months. Statistically significant differences were observed in survival and recurrence rates among the three groups (P < 0.001)
