[A case of metastatic liver tumor arising from gastric cancer resected after second-line chemotherapy].
A man in his 60s was diagnosed with gastric cancer and underwent distal gastrectomy and D2 lymph node dissection. The histological diagnosis was adenocarcinoma (T3, N1, StageIIB). He was treated with S-1 as adjuvant chemotherapy for 1 year. One year and 2 months after gastrectomy, a computed tomography (CT) scan revealed liver metastasis (S8, 38 mm). The patient was diagnosed with liver metastasis(refractory to S-1), and administered combination chemotherapy with irinotecan and cisplatin. After 4 courses of treatment, a CT scan detected a progressive liver tumor (55 mm). Combination chemotherapy with docetaxel and S-1 was selected as second-line chemotherapy. After 6 courses of treatment, the tumor size reduced to 40 mm in diameter, and no other metastasis was detected. Nine months after the diagnosis of liver metastasis, partial resection of the liver (S8) was performed. A pathological diagnosis of metastatic adenocarcinoma was determined, and the pathological therapeutic effect was rated as Grade 1b. Combination chemotherapy with docetaxel and S-1 was found to be effective, and was thus administrated after the operation. There have been no signs of recurrence for 6 months after the operation. Surgery with perioperative chemotherapy can be an effective treatment for liver metastasis from gastric cancer.
