The occurrence of gastrointestinal metastasis from lung carcinoma is rare. Compared with non-small cell lung cancer (NSCLC), small cell lung cancer more commonly results in this sort of metastasis. Here, we report an unusual case of NSCLC initially without evidence of distant metastasis that developed into gastric metastasis five months after the initial diagnosis, despite the primary lung cancer having a partial response to radiotherapy and chemotherapy. Serial radiological examinations and endoscopic biopsies of the gastric tumor confirmed that it was a metastatic carcinoma originating from the lung. The patient received a total gastrectomy for gastric metastasis due to repeated gastrointestinal bleeding.
肺癌胃肠道转移的发生率较低。与非小细胞肺癌（NSCLC）相比，小细胞肺癌更常导致这种转移。在这里，我们报告了一例非小细胞肺癌的不寻常病例，该患者最初无远处转移证据，但在初始诊断后 5 个月发展为胃转移，尽管原发性肺癌对放疗和化疗有部分反应。连续的影像学检查和胃肿瘤的内镜活检证实，这是一种来自肺部的转移性癌。由于反复胃肠道出血，患者接受了全胃切除术治疗胃转移。
