The possible use of percutaneous low output microwave tissue coagulation therapy (PLMCT) using ultra-sonography under local anesthesia for small solitary recurrent or metastatic liver cancer was studied.The subjects were 15 patients having recurrent or metastatic liver cancer with solitary liver tumor less than 4 cm in diameter.Consisting of 7 recurrent hepatocellular carcinoma and 8 metastatic liver cancers. PLMCT was performed at the output of 30 watt for 90 seconds at a time. Tumors less than 3 cm in diameter were completely coagulated by irradiation from 2 to 6 times judged by enhanced CT.No tumor recurrence was recognized in the coagulation area. Thus, the results suggested that PLMCT is a useful therapy for small solitary liver cancer especially, recurrence of hepatocellular carcinoma as a local control.
