Figure 3. aplan–Meier analyses of recurrence-free survival rates in patients with pancreatic neuroendocrine neoplasm who underwent limited resection according to risk score. The risk score suggests the number of risk factors for recurrence-free survival, such as G2-G3 and the presence of microvascular invasion, derived via a univariate analysis. The 3, 5, and 10-year recurrence-free survival rates of patients with risk scores of 0 (n=50) and 1-2 (n=12) were 100%, 100%, 100% and 100%, 90%, and 40%, respectively (p<0.001).
