[A case of advanced gastric cancer with liver metastases resected successfully after S-1 monotherapy and S-1/CDDP combination chemotherapy].

The patient was a 75-year-old man, who was diagnosed with type 3 gastric cancer with solitary liver metastasis whose diameter was 12 mm. Distal gastrectomy with D2 lymph node dissection was performed in June 2008. S-1 monotherapy (120 mg/day, day 1-28/42 days) for liver metastasis started as the first-line chemotherapy. After 3 courses, the diameter of liver metastasis enlarged to 22 mm. Moreover, S-1 and CDDP combined chemotherapy (S-1: 120 mg/day, day 1-21/ 35 days, CDDP: 60 mg/m2, day 8/35 days) was performed as the second-line chemotherapy, nevertheless the diameter of liver metastasis enlarged to 26 mm. No distant metastasis without solitary liver tumor was observed for 6 months after gastric resection, so a partial hepatic resection was performed in February 2009. Five months after the operation, the patient is doing well and shows no signs of recurrence of the cancer. A combination gastrectomy with D2 lymphadenectomy and postoperative chemotherapy was considered to be a radical treatment for H1, Stage IV gastric cancer.
