Trial Information

Microwave Ablation of Resectable Liver Tumors

Minimally invasive surgical alternatives are becoming more attractive for the treatment of
malignancy.The goal is to reduce morbidity and mortality and increase the ability to treat
patients in the outpatient setting. Image-guided ablation is becoming an attractive
alternative because of its relative low cost, its ability to provide large regions of
coagulative necrosis in a controlled fashion, and its relatively low toxicity. Although
image-guided ablative techniques have been extensively investigated for the treatment of
liver tumors, there has been limited experience with microwave ablation (MWA) in the liver.
This study will evaluate the treatment effect of MWA in liver tumors. Patients undergoing
planned surgical removal of liver tumors will have the tumors intra-operatively treated with
MWA. The histological changes will be evaluated upon removal of the specimen.
