A 62-year-old male was admitted because of lower left abdominal pain and diarrhea. The patient was diagnosed with rectal cancer and multiple liver metastases. First, the laparoscopic Hartmann operation with a D3 lymph node dissection was performed. After five cycles of folinic acid, 5-fluorouracil and oxaliplatin (FOLFOX) and bevacizumab, and one additional FOLFOX, the tumor markers dramatically decreased; with carcinoembryonic antigen levels ranging from 1096.3 to 7.6 ng/ml and carbohydrate antigen 19-9 levels ranging from 3248.0 to 42.1 U/ml. Computed tomography showed a bilateral 14 colorectal liver metastases which indicated stable disease by the Response Evaluation Criteria In Solid Tumors (RECIST) criteria and optimal morphologic response. A two-stage hepatectomy was performed to complete a curative resection because of the insufficient remnant liver volume. Five partial hepatic resections in the left liver and the right portal vein ligation were performed during the first operation. Thirty-four days later, a right hepatectomy was successfully performed. Pathologically, there was tumor necrosis in 90 percent of the area of the metastasized liver, and viable cells were detected in only a marginal part of the liver. The patient had an uneventful postoperative course and was discharged fifteen days after the second operation. Uracil-tegafur plus leucovorin was administered for 6 months as an adjuvant chemotherapy treatment. The patient is currently alive and has remained disease-free for more than 5 years. In conclusion, an ideal combination of perioperative chemotherapy and curative resection may provide a chance of long-term survival without recurrence of disease for selected patients with more than ten bilateral colorectal liver metastases.
