A 61-year-old man admitted to our hospital for diarrhea and general fatigue was found in endoscopic and radiological examination to have sigmoid colon cancer with multiple liver metastases. The patient underwent sigmoidectomy (S, type 2, 105x78 mm, sSI (urinary bladder), sN0 (0/22), sH3 (Grade C), sP0, sM0, sStage IV). Pathological report was following: tub2, pSI (urinary bladder), ly0, v1, pN0(0/22), PM0, DM0, RM0. After operation, the patient received systemic chemotherapy (CPT-11+UFT/LV) with hepatic arterial infusion therapy(HAI). We could not observe any severe adverse events. We conducted hepatectomy because of partial response by chemotherapy. As of this writing 41 months after surgery, the patient continues to do well with no signs of recurrence. The combination chemotherapy of CPT-11+UFT/LV with HAI was safe and effective treatment for the patients with unresectable liver metastases from colorectal cancer.
