We thank Drs Chetty and Serra for their great interest in our article.1 We concluded that patients with intraductal papillary mucinous neoplasms (IPMNs) have a higher risk of developing extrapancreatic neoplasms than those with mucinous cystic neoplasms and pancreatic ductal adenocarcinomas. Our conclusion is not yet definitive owing to the limited number of patients in our study, the rarity of similar reports, and the limitations associated with the retrospective method. However, our conclusions are further supported by similar findings in patients with IPMN.
