FIGURE 5. The Kaplan-Meier actuarial survival curves comparing patients with noninvasive intraductal papillary mucinous neoplasms (IPMNs, n = 84) and patients with IPMNs with invasive carcinoma (n = 52, P < 0.0001). Patients with noninvasive IPMNs had 1-, 2-, and 5-year survival rates of 97%, 94%, and 77%, respectively; patients with IPMNs with an associated invasive carcinoma had survival rates of 72%, 58%, and 43%, respectively.
