Core Tip

Core Tip: Branch duct-intraductal papillary mucinous neoplasms (BD-IPMNs) are the most common pancreatic cystic tumours. Size is the most important risk factor in patients with BD-IPMNs. A high diameter growth-rate is associated with malignancy as well. In our study, we demonstrated that volume is associated with the development of worrisome features and that a higher volume growth-rate can lead to a higher risk of worrisome features. Moreover, in our cohort, volume growth-rate in the first year of follow-up predicted the development of worrisome features. Based on these data, measuring volume could be a better tool than the diameter to predict early BD-IPMNs malignant transformation.
