Core Tip

Core Tip: Endoscopic treatment is the standard therapy for type I gastric neuroendocrine tumors, but it may not address underlying disease mechanisms. In this retrospective study of 128 patients, 41 experienced progression. Multivariate Cox regression identified adjuvant somatostatin analog use as a protective factor (hazard ratio = 0.38, 95% confidence interval: 0.17-0.90, P = 0.027) and neutrophil-to-lymphocyte ratio ≥ 2 as a risk factor (hazard ratio = 2.14, 95% confidence interval: 1.08-4.26, P = 0.030). Kaplan-Meier analysis confirmed both as independent prognostic variables. These findings suggest that combining endoscopic therapy with somatostatin analogues improves outcomes. Neutrophil-to-lymphocyte ratio may serve as a simple marker to guide risk stratification.
