Purpose: To evaluate the effectiveness of RFA for liver metastasis of colorectal cancer.Methods: We performed RFA in 442 patients from April 2006 to June 2008 at Kanto Medical Center NTT EC. It contained 88 (the total number) of liver metastasis of colorectal cancer.Results: We performed RFA in 47 patients (the actual number). The median age was 63 years-old (38-85) and 72.3% were male. The median tumor numbers were 5.5 (1-29) and median tumor size was 32mm (9-156). Thirty-four patients were performed chemotherapy before ablation. Three patients (3.4%) had complications; Liver abscess, hemoperitoneum and Liver failure. One year survival rate from the initial ablation was 80% and 2-year was 71%.Conclusion: We think performing RFA to liver metastasis which were unable to be resected or be continued chemotherapy might improve the prognosis.
