Selecting optimal surgical procedures for intraductal papillary mucinous neoplasm (IPMN): An analysis based on the Surveillance, Epidemiology, and End Result registry database

TP did not offer any significant OS and CSS benefits as compared to PD. However, for patients in stage T4 and AJCC stage III, TP may extend survival time in some degree. In older or histologically poorly differentiated patients, PD may be preferable to TP. The results are rational, but still warrant further verification due to limited sample volumes of specific subgroups.
