[Three cases with liver metastasis from gastric or colon cancer successfully treated with S-1 combined with CPT- 11].
ABSTRACT We report three cases with liver metastasis from gastric or colon cancer successfully treated with S-1 with CPT-11. Case 1: A total gastrectomy was performed for a gastric cancer located in the lower to upper body of the stomach (T3 (SE), N2, H0, P0, por 2, stage III B). Abdominal computed-tomography (CT) revealed a solitary liver metastasis in the S8 subsegment of the liver. We treated the patient with S-1 combined with CPT-11. Abdominal CT revealed a complete response (CR) after 5 courses. Case 2: Sigmoidectomy and partial resection of small intestine and abdominal wall were performed for sigmoid colon cancer. The intraoperative findings revealed liver metastases in left lobe of the liver (Si, N1, H1, P0, M0, tub 1, stage IV). After surgery, the patient was treated with S-1 combined with CPT-11. Abdominal CT demonstrated CR after 5 courses. Case 3: Laparoscopic right hemicolectomy was performed for ascending colon cancer (SE, N1, H0, P0, M0, tub 1, stage III a). Abdominal CT showed a solitary liver metastasis in the S6 subsegment of the liver 3 months after surgery. We treated the patient with S-1 combined with CPT-11. Abdominal CT revealed CR after 3 courses. The three cases are alive without any signs of recurrence.
