OBJECTIVES: The 2012 international consensus guidelines for the management of intraductal papillary mucinous neoplasm (IPMN) of the pancreas stratified patients into 2 clinical categories, "high-risk stigmata" and "worrisome features," and recommended different therapeutic strategies for these groups. The aim of this study was to elucidate the significance of these categories in terms of predicting malignant IPMNs. METHODS: The medical records of 100 consecutive patients who underwent pancreatectomy for IPMNs were retrospectively reviewed. Seventy patients with branch duct IPMNs (BD-IPMNs) were stratified into 3 groups. The relationships between the number of predictive factors and histopathologic grade were investigated. RESULTS: The prevalence rates of malignant IPMN, invasive carcinoma, and lymph node metastasis in the high-risk group were 80%, 55%, and 20%, respectively, with these percentages significantly increasing in a stepwise manner according to the number of predictive factors. In contrast, there was no significant correlation between the number of worrisome features and grade of malignancy in patients stratified as having worrisome BD-IPMNs. CONCLUSIONS: The number of high-risk stigmata correlated significantly with the grade of malignancy of BD-IPMNs. The presence of at least 1 high-risk stigma in patients with BD-IPMNs indicates a need for pancreatectomy with lymphadenectomy.
