Gastric neuroendocrine neoplasm with liver metastases: a case report

A 39-year-old women was admitted to our department with gastric mass and multiple liver space-occupying lesions found during health check-up. A gastroscopy showed an irregular ridge-like lesion at the lesser curvature of the stomach body (about 40 cm away from the incisor tooth); the pathological and immunohistochemical findings demonstrated the presence of a neuroendocrine tumor of well-differentiated (G1). An abdominal MRI indicated the possibility of multiple liver metastases and multiple perigastric lymph node metastases. After eight cycles of sandostatin treatment, a proximal subtotal gastrectomy + right hepatectomy + left partial hepatectomy + cholecystectomy were performed, and the diagnosis of gastric neuroendocrine neoplasm (gNEN) with liver metastases was confirmed. The patient recovered smoothly after operation and received sandostatin treatment just as pre-operation. We report a case of a gNEN with metastases by multimodality therapy with a view of the literature.
