The purpose of this protocol is to pathologically evaluate the destruction by microwave ablation of primary and metastatic liver tumors. The primary aim is to measure tissue destruction with the MedWaves Microwave Ablation/ Coagulation Ablation System.

Condition Intervention
Hepatocellular Carcinoma
Liver Cancer

Primary Outcome Measures:
  • Measure of the tissue destruction with the MedWaves Microwave Ablation/ Coagulation Ablation System [ Time Frame: 30 Days ] [ Designated as safety issue: No ]

Estimated Enrollment: 50
Study Start Date: April 2009
Estimated Primary Completion Date: April 2015 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: Microwave Ablation
    Tumor tissue from the liver is inter-operatively treated with the microwave ablation device to measure the destruction of tissue.
Detailed Description:

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.
