The microwave coagulo-necrotic therapy with perctaneousmicrowave needle for deep lesion were performed in 7 tumor lesions of 4 patients. They were 2 hepatoceller carcinomas and 2 metastatic liver carcinomas. Each 7 lesions existed in inside from liver surface. At laparotomy, monopolar electrodes were inserted with an ultrasonic guide. One round of coagulation lasted for 30 seconds at 60w. Except for one patient (Esophageal cancer with liver metastasis), 3 patients are alive for 12-16 months. Almost of complications were not observed after this therapy. This method acts directly on tumors and is simple and safe. In this time, microwave coagulation for liver tumor were underwent, because of hepatic dysfunction, multiple liver tumor or absolute unresection of primary lesion. Therefore, it seems to expect as a useful means for regional treatment of tumors. But, through the repeated experience of various cases, we must decide the indication of this therapy.
