A 41-year-old woman with type 3 advanced gastric cancer and Virchow lymph node, para-aortic lymph node, and multiple bone metastases was diagnosed with U-less cType 3 cT4aN3M1, cStage IV. We administered docetaxel, cisplatin, and S-1 (DCS)therapy for unresectable gastric cancer. After 11 courses of DCS, we confirmed that the distant lymph node metasta- ses were significantly reduced. We performed radiotherapy(30 Gy/10 Fr)on the thoracic lumber vertebrae. Because the patient was successfully downstaged, we performed total gastrectomy with Roux-en-Y reconstruction. The histopathological diagnosis was ypT3N2M0, ypStage III A. In this case, DCS therapy successfully treated gastric cancer with distant metastases, including multiple bone metastases.
