Study Summary
RATIONALE: Radiofrequency ablation is a procedure that heats tumors to several degrees above body temperature and may kill tumor cells. PURPOSE: Phase II trial to study the effectiveness of radiofrequency ablation in treating patients who have unresectable primary or metastatic liver cancer.
Primary Outcome
Standard response criteria will be used to assess the CT (computed tomography) scan images on a lesion per lesion basis. Complete response is complete disappearance of the index lesion on followup scan when compared to the pretreatment images. Partial response is a decrease of 50% or greater in the product of the perpendicular diameters of the measured lesion following treatment compared to the pretreatment images. Minor response is a decrease between 25% and 49% in the product of the perpendicu
Interventions
