概要	OBJECTIVES:The aims of the study were to compare survival outcomes between patients with pancreatic ductal adenocarcinoma (PDAC) and invasive intraductal papillary mucinous neoplasms (IPMN) and to determine candidates for adjuvant chemotherapy.METHODS:A total of 579 consecutive patients, including 375 PDAC and 204 IPMN patients, were reviewed. Stage-matched comparisons of survival data were conducted using the Cox proportional hazards model and propensity analysis. To evaluate prognostic factors, univariate and multivariate Cox regression analyses were performed.RESULTS:The overall survival for invasive IPMN was significantly longer than that for PDAC (hazard ratio, 2.34; P = 0.0001). When the analysis was limited to stage I patients, the 5-year overall survival rate of invasive IPMN patients was significantly better than that of PDAC patients (100% vs 74.1%, P = 0.0092); however, no difference was observed between stage II patients with invasive IPMN and PDAC (hazard ratio, 1.49; P = 0.09). The Cox proportional hazards model and propensity analysis demonstrated no difference in stage-matched survival. Multivariate analysis revealed that only T (≥3) was an independent prognostic factor for invasive IPMN.CONCLUSIONS:Stage-matched analysis did not show a significant survival difference between invasive IPMN and PDAC patients, and T3 or higher was an independent prognostic factor for invasive IPMN.
