Core Tip: Gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) encompass a heterogeneous group of tumors with unique indolent biological behavior. The role of surgery in high-grade or advanced GEP-NENs is still controversial. There are several highlights of this review. First, we address the surgical benefits of selected high-grade GEP-NENs and summarize the tumor biological markers correlated with a prognosis. Second, we review various surgical strategies, including curative resection, debulking, resection after neoadjuvant therapy for metastatic GEP-NENs, and the latest clinical evidence. Finally, liver transplantation presents a curative therapeutic option for GEP-NEN patients with liver metastasis. We summarize the new findings and propose directions for future development.
