Incidence of Lymph Node Metastases and Impact of Radical Surgery for Duodenal Neuroendocrine Tumors

Despite the high frequency of regional lymph node (LN) metastases associated with duodenal neuroendocrine tumors (D-NETs), the impact of these metastases on survival and the ideal extent of LN dissection are unknown. We used the National Cancer Database (NCDB) to investigate factors associated with survival, including LN metastases and types of surgery, in patients with D-NETs.All patients with D-NETs recorded in the NCDB between 2004 and 2016...
