[Preoperative chemotherapy enabled radical resection of tumors in a patient with multiple liver metastases].

The patient was a 61-year-old man with a prominent epigastric mass and dull pain. Sigmoid colon cancer and multiple hepatic metastases were diagnosed upon examination. The liver metastases were adjacent to the right hepatic artery and the portal vein; therefore, the patient received preoperative bevacizumab+XELOX (capecitabine plus oxaliplatin) chemotherapy. After 6 courses of chemotherapy, a sufficient partial response (PR) was achieved to secure a surgical margin during radical resection of the tumors. The patient is alive, without recurrence, 10 months after surgery. This report highlights the importance of securing a surgical margin during conversion therapy and reviews evidence from previous literature reports.
