BACKGROUNDS/AIMS: International treatment guidelines for branch duct intraductal
papillary mucinous neoplasm (BD-IPMN) of the pancreas have been proposed, for
features associated with malignancy and invasiveness. We investigated the
clinicopathological characteristics that are predictive of malignancy or
invasiveness and disease recurrence. METHODS: A review of 324 patients with
resected and pathologically confirmed BD-IPMN, between March 1997 and December
2013, was conducted. RESULTS: There were 144 (44.4%) low grade dysplasia (LGD),
138 (42.6%) intermediate grade dysplasia (IMGD), 17 (5.3%) high grade dysplasia
(HGD), and 25 (7.7%) invasive carcinoma (invIPMC) cases. The 5-year survival
rates were 98.1% for LGD, 95.3% for IMGD, 100% for HGD, and 71.8% for invIPMC.
Through a univariate analysis, the male sex was associated with malignancy, and
CA19-9 was related to both malignant and invasive IPMN. The high risk or
worrisome features of the international guidelines were associated with both
malignant and invasive IPMN: the total bilirubin of the head/uncinate lesion,
tumor size, mural nodule, and the size of the main pancreatic duct (MPD). Through
a multivariate analysis, the male sex, elevated CA19-9, mural nodule, and dilated
MPD diameter were independently correlated with the malignant IPMN. The elevated
CA19-9 and dilated MPD diameter were also correlated with invasive carcinoma. The
patient age and the initial pathological diagnosis were strongly associated with
disease recurrence following surgical resection. CONCLUSIONS: The high risk or
worrisome features in the current treatment guidelines for BD-IPMN are confined
to the morphological characteristics of the disease. Patient factors and
biological features should also be considered in order to develop optimal
therapeutic or surveillance strategies.
