ABSTRACT

Objective To assess the clinical value of transcatheter arterial chemoembolization(TACE) for the treatment of metastatic liver leiomyosarcoma(MLL).Methods CT triphasic scanning and TACE were performed in 8 patients with MLL,which was proved by fine-needle aspiration biopsy and immunohistochemical study.A follow-up of 1-3 years was conducted.Based on the enhancement degree of the hepatic lesion and the DSA manifestations of the lesion,which were observed both before and after TACE,and also on the survival time,the therapeutic effectiveness was evaluated.Results Of the eight cases,single metastasis was seen in 3 and multiple metastasis in 5.Excellent result was obtained in 6 cases and good result in 2 cases.Based on the imaging findings,marked effect was seen in 3 cases,good effect in 4 cases and no improvement in one case.The surviva1 rate at 1,2 and 3 years was 87.8%,50.0% and 37.8% respectively.Conclusion TACE is a safe and effective treatment for MLL.
