Abstract
AbstractThe treatment plan for non-ampullary duodenal neuroendocrine tumors (d-NETs) with diameters 1–2 cm remains controversial. We therefore aimed to compare the prognostic effects of endoscopic treatment and surgical resection on non-ampullary d-NETs with 1–2 cm diameters. A total of 373 eligible patients were identified from the Surveillance, Epidemiology, and End Results (SEER) database. Propensity score matching (PSM) was performed to match patients 1:1 according to clinicopathological characteristics. Disease-specific survival (DSS) and overall survival (OS) were calculated. Before PSM, there was no significant difference in DSS or OS (all P > 0.05), but the T stage, N stage, and TNM stage were significantly different between the two surgical methods (all P < 0.05). After 1:1 PSM, the differences in clinicopathological characteristics were significantly reduced (all P > 0.05). Survival analysis showed that tumor grade was correlated with DSS and that age was correlated with OS (all P < 0.05); however, the surgical method and other clinicopathological characteristics were not correlated with prognosis (all P > 0.05). Subgroup survival analysis of patients with T2N0M0 disease and tumors invading the lamina propria or submucosa showed that the 5-year DSS and OS rates were not significantly different according to the surgical approach (all P > 0.05). The surgical approach has no significant effect on the prognosis of patients with non-ampullary d-NETs with 1–2 cm diameters, especially those with T2N0M0 disease. This suggests that endoscopic treatment may be a preferred option for these patients.
