Abstract

Small (≤2cm) pancreatic neuroendocrine tumors (PNETs) are a unique subset of pancreatic neoplasms. Chromogranin A levels (CgA), mitotic rate, and histologic grade are often used to characterize PNET behavior, but debate continues around long-term clinical outcomes in small tumors. This study evaluates the survival impact of these factors in a US population.
