ABSTRACT

ObjectiveTo evaluate the effect of ultrasound guided radiofrequency ablation (RFA) on malignant liver tumors.Methods82 patients of primary liver cancer and 49 patients of metastatic liver cancer with a total of 226 cancer foci underwent percutaneous ultrasound guided RFA.ResultsCT performed 1 day～1 month post treatment showed a complete ablation in 203(90%) nodules. One hundred and six patients were followed up for 3～26 months, the survival rate of 3, 6 months and 1 year was 98 1%(104/106), 85 7%(72/84) and 73 7%(42/57), respectively. The major post RFA complications occurred in 6 cases(4 6%) including hemorrhage, hepatic abscess, bile leak, and cholecystitis with no mortality.ConclusionUltrasound guided RFA for the treatment of malignant hepatic tumors has the advantage of good palliative results, easy compliance by the patients, and enabling repeated therapy.
