[Usefulness of percutaneous microwave tissue coagulation therapy for solitary liver cancer].
The possible use of percutaneous transhepatic microwave tissue coagulation therapy (PMCT) using ultra-sonography under local anesthesia for solitary liver cancer was studied. The subjects were 8 patients having primary or metastatic liver cancer with solitary liver tumor less than 4 cm in size, consisting of 2 hepatocellular carcinomas, and 6 metastatic carcinomas. PMCT was performed continuously 3 times at the output of 30 watts for 30 seconds at a time. Tumors less than 3 cm in size were completely coagulated by irradiation from 2 to 5 times judged by enhanced CT. No recurrence of tumor was recognized in the coagulation area. But in some cases, multiple metastases were found at another site in the liver by 3 months after PMCT. Thus, the results suggest that PMCT is a useful therapy for small liver tumor as a local control.
