Abstract

Merits of percutaneous low output microwave tissue coagulation therapy (PLMCT) is following that coagulation area is distinctly observed by ultra-sonography, because of no bubbling through irradiation. PLMCT can be performed under local anesthesia. Size of coagulation area by PLMCT and high output PMCT are the same.
The possible use of PLMCT using ultra-sonography under local anesthesia for small solitary recurrent or metastatic liver cancer was studied.
The subjects were 19 patients having recurrent or metastatic liver cancer with solitary liver tumor less than 4 cm in diameter between September 1994 and July 2010.
No tumor recurrence was recognized in the coagulation area. Thus, the results suggest that PLMCT is a useful therapy for small solitary liver cancer especially, recurrence of hepatocellular carcinoma as a local control.
