Abstract
Gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) are highly heterogeneous tumors. According to the 2019 World Health Organization classification and grading criteria for neuroendocrine neoplasms of the gastrointestinal tract and hepatopancreatobiliary organs, GEP-NENs include well-differentiated neuroendocrine tumors (NETs), poorly differentiated neuroendocrine carcinomas (NECs), and mixed neuroendocrine-non-neuroendocrine neoplasms (MiNENs). GEP-NETs may present as hormonally functioning or nonfunctioning tumors and may have distinct clinical features based on their sites of origin. The Expert Committee of Neuroendocrine Tumors, Chinese Society of Clinical Oncology revised and updated the 2016 version of Chinese expert consensus on GEP-NENs. The update the consensus includes the epidemiology, clinical manifestations, biochemical and imaging examinations, pathological features, and treatment and follow-up of GEP-NENs.
