Two Cases of Surgery Combined with Intraoperative Radiofrequency Ablation for Colorectal Cancer and Synchronous Liver Metastases

The therapeutic management of simultaneous liver metastasis of colorectal cancer(SCRLM)remains controversial. Although hepatic metastasectomy is the first choice for resectable liver metastasis of colorectal cancer, radiofrequency ablation (RFA)is one of the least invasive application for patients who refuse more invasive treatment such as hepatectomy and longterm systemic chemotherapy or for whom such treatment is not suitable. We report 2 cases of SCRLM treated by surgery combined with intraoperative RFA and adjuvant chemotherapy, raising the possibility of local control in the liver for selected patients.
