An oral anticancer drug, TS-1, enabled a patient with advanced gastric cancer with Virchow's metastasis to receive curative resection.
We encountered a patient with advanced gastric cancer, with Virchow's lymph node metastasis, who subsequently underwent curative resection after neoadjuvant chemotherapy with the newly developed oral anticancer drug, TS-1. The patient was a 67-year-old woman who had a type 2 tumor in the middle third of the stomach, and Virchow's lymph node metastasis, which was diagnosed by fine-needle aspiration cytology; she also had swollen paraaortic lymph nodes. Curative resection was considered impossible, and TS-1 (100 mg/day) was administered for 28 days in one course, mainly in the outpatient clinic. Although grade 2 stomatitis interrupted the therapy on day 21 of the second course and on day 7 of the third course, the type 2 tumor showed marked remission (partial response; PR) and the metastasis in the Virchow's and paraaortic lymph nodes had completely disappeared after the third course (complete response; CR). Eleven weeks after the completion of the TS-1 treatment, total gastric resection with D3 lymph node dissection was performed. Histopathological examination revealed tumor involvement only in the mucosal and submucosal layers of the stomach and the no. 4d lymph node. Most of the tumor was replaced with fibrosis with granulomatous change in the muscularis propria of the stomach and in the no. 3, no. 6, and no. 7 lymph nodes. This may be the first report of a patient with advanced gastric cancer with Virchow's lymph node metastasis who successfully received curative resection following neoadjuvant chemotherapy with a single oral anticancer drug.
