[A surgical (right lobectomy) case of liver metastasis of colon cancer after chemotherapy using mFOLFIRI and cetuximab].

A man in his early seventies underwent low anterior resection and partial resection of the liver for the rectal cancer and liver metastasis. However, 4 months after the surgery, he was found to have a liver tumor at S5 and S7 by abdominal CT scan. Then, he underwent chemotherapy (mFOLFOX6), but the metastatic tumor was progressive. We selected FOLFIRI + cetuximab regimen for second-line therapy to resect the metastatic tumor. As the metastatic lesion was become smaller after 4-course of the regimen including cetuximab, we decided to perform a radical resection. We conducted a right lobectomy of the liver, and the tumor was completely resected.
