| [ Summary ] |
The efficacy of microwave coagulation therapy (MCT) and radio frequency ablation (RFA) for metastases of colorectal cancer are discussed. Many patients with hepatocellular carcinoma have received these therapies and their efficacy is well known. However, the gold standard of therapy for metastatic colorectal cancer is resection, so the efficacy of MCT and RFA, in these cases is not well known. Small scale trials (maximum of 117 patients) were done with patients who had refused operations or were inoperable. The results were variable, but not unsatisfactory. The best result was for a 5-year survival rate after MCT, being 38% (n=40). More investigations need to be done, but MCT and RFA may be effective for metastases associated with colorectal cancer in conjunction with surgery. |
