Impact of surgery and surveillance in the management of branch duct intraductal papillary mucinous neoplasms of the pancreas according to Fukuoka guidelines: the Bologna experience

The objective of the study was to evaluate the Fukuoka guidelines in indicating the proper management for recognising the risk factors of malignancy. Data of patients with branch duct intraductal papillary mucinous neoplasms who underwent pancreatic resection or surveillance according to the Fukuoka risk parameters were collected in a prospective database. The clinical outcome (development of pancreatic cancer, overall and disease-specific survival) and pathological results were evaluated in all patients and in resected cases, respectively. The data of 197 patients were collected: 23 primarily resected and 174 primarily followed. Of the latter, 16 were secondarily resected. Among the patients resected, 21 (53.9%) showed diagnosis of in situ or invasive carcinoma and only contrast-enhancing mural nodules were significantly related to malignancy (P = 0.002), with a DOR of 3.3 and an LH+ of 2.2. Development of pancreatic cancer was shown in ten (5.7%) of the patients primarily followed. The overall survival and disease-specific survival were similar between patients primarily followed and primarily resected. It seems reasonable to suggest that a branch duct intraductal papillary mucinous neoplasm should be treated as a benign and indolent disease that is rarely malignant. Enhancing mural nodules represent the best indicator for surgery.
