Clinical Research of Combining Percutaneous Radiofrequency Ablation with Thanscatheter Arterial Chemoembolization to Hepatoma

Objective To assess the method and the effect of combining percutaneous radiofrequency ablation with thanscatheter arterial chemoembolization to the hepatoma. Methods 31 nodules in 16 patients,who were biopsy proved hepatoma,were treated by the thanscatheter arterial chemoembolization 1 week or 2 after percutaneous radiofrequency ablation. Results Complete response,partial response(residual hepatoma)were found on selective hepatic angiography in 12 of 14 small nodules(85.7%),at the edge of the tumor near the liver surface in 17 big nodules and at the special site in 2 small ones(61.3%),respectively.Local tumor growth was found 3 months after the combining therapy.The disease free survival was 75%(12/16)more than half a year.The manifestation was obviously improved in all the patients. Conclusion The way of combining percutaneous radiofrequency ablation with thanscatheter arterial chemoembolization can find and treat the residual nodules.Therefore,it can increase the therapeutic effects of the disease.
