We report the case of a 64-year-old man who underwent resection on two occasions for recurrent renal cell carcinoma. He first underwent right nephrectomy for renal cell carcinoma, and 10 years later, he underwent pylorus-preserving pancreaticoduodenectomy for pancreatic metastasis. Microscopic extracapsular invasion without lymph node metastasis was observed at that time. Twelve years after the first surgery, he was diagnosed with stomach metastasis. Clinically, metastases to other organs was not observed, and endoscopic ultrasonography revealed no changes in the submucosal layer; endoscopic submucosal dissection was subsequently performed. Pathologically, the tumor was found to be localized in the mucosal layer. There has been no occurrence of metastases for 2 years and 6 months since the last surgery.
我们报告了一例64岁男性患者，该患者因复发性肾细胞癌接受了两次手术切除。他首次因肾细胞癌接受了右肾切除术，10年后，因胰腺转移接受了保留幽门的胰十二指肠切除术。当时观察到显微镜下有包膜外侵犯，但无淋巴结转移。首次手术后12年，他被诊断为胃转移。临床上，未观察到其他器官转移，内镜超声检查显示黏膜下层无变化；随后进行了内镜黏膜下剥离术。病理检查发现肿瘤局限于黏膜层。自上次手术以来的2年6个月里未发生转移。
