FIGURE 6. The Kaplan-Meier actuarial survival curves comparing patients with IPMN adenomas (n = 14), borderline IPMNs (n = 24), and IPMNs with CIS (n = 46). There were no differences in survival among the 3 noninvasive groups. The 5-year survival rates were 80%, 72%, and 78% for adenoma, borderline, and CIS, respectively (P = NS).
