根治切除不能肝癌に対する術中Microwave coagulation therapy（MCT）の有用性

Three cases with unresectable liver cancer treated with intraoperative microwave coagulation were reported in this article.Case 1 : 61-year-man with a severe hepatic dysfunction, operated for HCC in S3, was found to have another small HCC in S8 which was treated by intraoperative microwave coagulation.Case 2 : 63-year-man with a severe hepatic dysfunction was treated by intraoperative microwave coagulation for a huge HCC in S5-8 with additional chemolipiodol therapies.Case 3 : 53-year-woman had liver (S4) and lung metastases after resection of rectal cancer. Liver lesion was treated by intraoperative microwave coagulation combined with chemotherapies for lung metastases. All these cases are alive after the microwave coagulation for 33, 18 and 24 months respectively with no regrowth of liver tumors. No severe complications were observed except liver dysfunctions in all cases. This therapy was considered to be useful clinically for unresectable liver cancer.
