We describe the case of a 74-year-old man with liver resection for originally unresectable liver metastasis from colorectal cancer after multiagent chemotherapy. Eleven bilobar liver metastases appeared four months after curative resection for double cancer of sigmoid colon and upper rectum. After 6 courses of multiagent chemotherapy (mFOLFOX 6 with bevacizumab), the number of liver metastasis decreased from 11 to 5. The patient underwent curative resection for liver metastasis. A new lesion of 7 mm in the segment 6 appeared 8 months after an initial liver resection. After 3 months' observation, two more liver metastases appeared. All liver metastases were resected. Solitary lung metastasis appeared 10 months after the second liver resection. The lung metastasis was also resected. The patient was alive with no evidence of disease in 33 months after the initial liver resection. We experienced the case with repeated liver resections after multiagent chemotherapy for originally unresectable bilobar liver metastasis. The therapeutic strategy which combines surgical resection with cytotoxic chemotherapy will be important more than ever.
