Background: There are no reports of concurrent chemoradiotherapy for gastric cancer with peritoneal oligometastases. Case description: A 70-year-old man with gastric cancer and peritoneal oligometastases received concurrent adaptive radiotherapy and oral S-1. After radiotherapy, S-1 was discontinued, and 2 years later the tumor had completely regressed, with no recurrence or metastasis 6 years after radiotherapy. Conclusion: Peritoneal oligometastatic gastric cancer may be a candidate for curative treatment with concurrent adaptive radiotherapy and oral S-1.
