BACKGROUND Gastric mixed neuroendocrine-non-neuroendocrine neoplasm(MiNEN),which consists of neuroendocrine and non-neuroendocrine components,is quite rare.Until now,most data on gastric MiNEN come from clinical cases,without largescale retrospective studies or controlled clinical trials.Consequently,no consensus regarding the origin,molecular characteristics,or appropriate treatment of MiNEN has been reached so far.We conducted chemotherapy of irinotecan plus cisplatin(IP regimen)and surgery in two patients with gastric MiNEN,which had never been used in treating this kind of tumor,leading to their long-term survival for more than 3 and 7 years,respectively.CASE SUMMARY We present two patients(one male and one female)with gastric MiNEN,with the primary manifestation of recurrent upper abdominal pain.After they were referred to our hospital,a diagnosis of gastric MiNEN was defined with the help of CT scan,and histopathological and immunohistochemical examinations on the samples of gastrointestinal endoscopy or radical surgery.The male patient(case 1)were found to have metastases in the reginal lymph nodes and the left liver.He received four cycles of IP regimens first,then the gastrectomy and partial left liver resection,followed by additional two cycles of IP chemotherapy.The female patient(case 2)underwent a laparoscopic gastrectomy,and received six cycles of IP regimen.She was found to have metastatic lesions in the right lung 2 years after that,and underwent video-assisted thoracoscopic surgery(VATS)of the lower lobe of the right lung.The two patients have now survived for more than 3 years and 7 years,respectively,without any evidence of recurrence or metastases.CONCLUSION IP regimen,combined with curative-intent surgery if feasible,could be considered as the priority in the choice of front-line chemotherapy for gastric MiNEN. 展开更多
