Background. In the present study, we report two cases of gastric metastasis arising from lung cancer treated with gastrectomy. Cases. Case 1 involved a woman in her 60's diagnosed with lung cancer and who subsequently underwent left upper lobectomy. A three-month follow-up period with computed tomography revealed a gastric tumor, and gastroendoscopic images showed a submucosal tumor. We diagnosed the patient with primary gastric cancer and performed total gastrectomy; however, the pathological findings showed metastatic adenocarcinoma arising from lung cancer. Furthermore, after three months, multiple liver metastases appeared, which were treated with chemotherapy. Nevertheless, the liver tumors proliferated, and the patient died three months postoperatively. Case 2 involved a man in his 70's who had been diagnosed with lung cancer and underwent left lower lobectomy and lingulectomy. Two years after the surgery, he was admitted for gastrointestinal hemorrhage resulting from gastric cancer. We then performed completion gastrectomy to cure the hemorrhage, and the patient was diagnosed as having metastatic growth from lung cancer. However, he died six months after gastrectomy. Conclusions. In lung cancer patients who complain of digestive symptoms, physicians should perform endoscopy and search for any possible metastasis of lung cancer according to the characteristic findings.
