Abstract
The possibleuse of percutaneous tranhepatic microwave tissue coagulation therapy (PMCT) by using ultrasonography under the local anesthesia for solotaru liver cancer was studied in this paper.
Eight patients that was primary or metastatic liver cancer with solitary liver tumor less than 4 cm in size, consisting of 2 hepatocellular carcinoma, 6 metastatic carcinoma. PMCT was performed continuously 3 times at the out put of 30 watts for 30 seconds at a time. Tumor less than 3 cm in size was completely coagulated by enhanced CT.
The coagulation area was not recognized recurrence of the tumor. But, in some cases, multiple metastases were recognized another site in the liver by 3 months after PMCT. Thus the results suggest that PMCT is the useful therapy for the small liver tumor as a local control.
