Pathologically complete response of multiple liver metastases from rectal cancer treated with mFOLFOX6 plus bevacizumab

We report a case of pathologically complete response of multiple liver metastases from rectal cancer after neoadjuvant chemotherapy. The patient was a 74-year-old woman who had advanced rectal cancer with synchronous liver metastases (T4N1M1). Following resection of the primary tumor, she received biweekly mFOLFOX6 plus bevacizumab neoadjuvant chemotherapy. After 5 courses, the liver tumors were markedly reduced in size. Three weeks after the final treatment, she underwent partial hepatectomies. Histologically, no cancer cells were detected in any resected specimens. The postoperative course was uneventful, and she has been well without recurrence for one year at the time of writing. Regimens containing bevacizumab may result in good tumor response. Surgical resection is crucial for proof of pathologically complete response.
