Core Tip	Pancreatic neuroendocrine tumors (PNETs) are relatively uncommon but represent the second most frequent pancreatic neoplasm. This study, conducted in Colombia, challenges conventional size-based survival expectations for PNETs and advocates a surgical approach, even for tumors smaller than 2 cm. The findings underscore the importance of considering histological traits like lymphovascular and neural invasion, high mitotic index, and a Ki67 proliferation index exceeding 3%. These characteristics, traditionally associated with larger tumors and higher mortality rates, were also identified in a significant fraction of smaller tumors. More comprehensive studies are necessary to redefine clinical approaches and guidelines for managing PNETs.
