Over the last 40 years,the incidence and prevalence of gastroenteropancreatic neuroendocrine neoplasms(GEP-NENs)have continued to increase.Compared to other epithelial neoplasms in the same organ,GEP-NENs exhibit indolent biological behavior,resulting in more chances to undergo surgery.However,the role of surgery in high-grade or advanced GEP-NENs is still controversial.Surgery is associated with survival improvement of well-differentiated highgrade GEP-NENs,whereas poorly differentiated GEP-NENs that may benefit from resection require careful selection based on Ki67 and other tissue biomarkers.Additionally,surgery also plays an important role in locally advanced and metastatic disease.For locally advanced GEP-NENs,isolated major vascular involvement is no longer an absolute contraindication.In the setting of metastatic GEP-NENs,radical intended surgery is recommended for patients with low-grade and resectable metastases.For unresectable metastatic disease,a variety of surgical approaches,including cytoreduction of liver metastasis,liver transplantation,and surgery after neoadjuvant treatment,show survival benefits.Primary tumor resection in GEP-NENs with unresectable metastatic disease is associated with symptom control,prolonged survival,and improved sensitivity toward systemic therapies.Although there is no established neoadjuvant or adjuvant strategy,increasing attention has been given to this emerging research area.Some studies have reported that neoadjuvant therapy effectively reduces tumor burden,improves the effectiveness of subsequent surgery,and decreases surgical complications. 展开更多
