Gastric neuroendocrine tumors are rarely seen in the gastric tumors, because there are few case reports and the clinical diagnosis rate is low. There is no consensus treatment method in the world. However, with the benefit of esophagogastrodenoscopy and widespread use of proton pump inhibitors, the diagnostic rate of gastric neuroendocrine tumors is on the increase, which gives us an updated understanding for the pathogenesis and pathophysiology of the disease. By studying its pathogenesis, scholars have found that hypergastrinemia caused by various causes is closely related to its occurrence. Gastric neuroendocrine tumors are classified into different types or pathological grades depending on the state of progression of the disease and the unique clinical manifestations. Clinically used diagnostic methods include gastroscopy, medical imageology, nuclear medicine, gastrin, CgA, etc. There are also differences in treatments depending on the clinical classification. If the disease progresses rapidly and the grade is high, surgical resection of the lesion plus postoperative adjuvant chemotherapy should be actively performed. Other better treatments are still being explored.
胃神经内分泌肿瘤是临床较少见的一类肿瘤性病变，由于病例报道少，临床诊断率较低，在国内外尚无统一的诊疗方法。得益于内镜技术的发展以及临床上广泛应用的质子泵抑制剂，胃神经内分泌肿瘤的发病率和诊断率呈现上升的趋势。通过研究其发病机制，学者发现其发生与各种原因引起的高胃泌素血症密切相关。根据疾病的进展状态和临床表现，学者对胃神经内分泌肿瘤进行了分型和病理分级。临床上运用的诊断方法有胃镜、影像学、核医学、胃泌素、CgA等检查。根据临床分型的不同，治疗手段也存在差异，如果疾病进展迅速且分级较高，则应积极行外科手术切除病灶加术后辅助化学药物治疗。其他更好的治疗方法还在不断探索中。.
