Abstract:
To study the value of the treatment of hepatocellular carcinoma with B ultrasonographic located radiofrequency ablation(RFA).Methods: The radiofrequency multielectrodes were inserted into the hepatic carcinoma with B ultrasonographic locating.RFA was applied with the power from 50W up to 90W. RFA scope was 1cm out of the margin of the tumor mass in three dimension. After RFA treatment, the AFP level changes and the B ultrasonography, computed tomography (CT), biopsy of the liver and hepato arterioangiography were observed.Results: One month after RFA treatment ,in those with abnormal AFP level AFP falled to normal in 18/20 patients, the volume of the tumor mass were enlarged in 9 patients, not changed in 8 patients and decreased in the others at CT and/or ultrasonography. The alive cancer cells in the margin of the tumor mass were found in 1/6 patients at biopsy. The scattering bloodstream in the carcinoma was showed in 1/8 patients on hepato arteriography. After three months, the volume of the tumor was remarkably decreased in 25 patients.Conclusion: The results suggests that RFA appears to ablate hepatic carcinoma effectively as suitable method mastered.
