[A case of rectal cancer with liver metastases successfully treated with modified FOLFOX6 therapy]

We report a case of a 71-year-old male with rectal cancer accompanied by liver metastases. Abdominal CT scan revealed a hepatic tumor (S2, 3) about 4 cm in diameter. We performed a Mile's operation and planned to resect the liver metastases after chemotherapy of modified FOLFOX6(mFOLFOX6)regimen: l-leucovorin (200 mg/m2) and oxaliplatin (85 mg/m/2) were given as a 2-hour infusion followed by bolus injection of 5-FU 400 mg/m2 and a 46-hour infusion 5-FU 2,400 mg/m2 every 2 weeks. An abdominal CT scan 6 months later demonstrated regression of the liver metastases. Hepatectomy was performed after chemotherapy, and no viable tumor cells were seen.
