Gastric neuroendocrine tumor treated with endoscopic submucosal dissection

Abstract A case of a 59-year-old male patient with gastric neuroendocrine tumor which was misdiagnosed as adenocarcinoma, is presented. Herein, primary diagnosis was made due to the similarity of endoscopic pictures of both diseases and dues to the inappropriate interpretation of a small biopsy sample. The patient was qualified for endoscopic submucosal dissection. Microscopic examination of whole lesion, supplemented by immmunohistochemical reactions (chromogranin A, synaptophysin, cytokeratins 7 and 20, Ki67) revealed gastric neuroendocrine tumor (NET) G2. The lesson learnt is that to provide effective treatment to the patient, it is necessary to use all available methods to make a proper diagnosis and to distinguish the suspected disease from others with similar features.

Submucosal Dissection

Objective: To study the therapeutic effect of endoscopic submucosal dissection and mucosal resection on gastric neuroendocrine tumor. Methods: A hundred patients with gastric neuroendocrine tumor that were treated in the Affiliated Hospital of Chifeng University from January 2016 to May 2021 were randomly selected for this research. They were divided into two groups, which were the control group (endoscopic mucosal resection) and the study group (endoscopic submucosal dissection), by the digital table method. The curative effects of the two groups were observed and compared. Results: Before operation, there were no significant differences in serum CgA, TNF-?, and IL-6 between the two groups, p > 0.05. After surgical treatment, the operation time and hospital stay of the patients in the study group were shorter than those in the control group, the amount of surgical bleeding was also less compared to the control group, and the complete tumor resection rate was higher than that in the control group (p < 0.05); the levels of IL-6 and CgA of the study group were lower than those in the control group, while the levels of TNF-? were higher than those of the control group, p < 0.05; the postoperative complication rate of the study group was lower than that of the reference group (p < 0.05). Conclusion: Endoscopic submucosal dissection is more effective for gastric neuroendocrine tumors. The resection rate of the tumor is high, and the operation risk is low.
