Comparison on efficacy and safety of TACE combined with 125I seeds implantation or lenvatinib for treating hepatocellular carcinoma complicated with portal vein tumor thrombosis / 中国介入影像与治疗学

ABSTRACT

Objective To comparatively observe the efficacy and safety of TACE combined with 125I seeds implantation or lenvatinib for treating hepatocellular carcinoma(HCC)complicated with portal vein tumor thrombosis(PVTT).Methods Totally 52 HCC patients complicated with type Ⅱ or type Ⅲ PVTT were enrolled and divided into TACE combined with 125I seeds group(group A,n=27)and TACE combined with lenvatinib group(group B,n=25).Objective response rate(ORR),overall survival(OS)and incidence rate of adverse reaction were compared between groups.Results ORR,the median OS,median OS of type Ⅱ PVTT and median OS of type Ⅲ PVTT was 70.37%(19/27),13.6 months,14.1 months and 13.2 months in group A,and 32.00%(8/25),11.3 months,12.3 months and 10.4 months in group B,respectively.The above indexes in group A were all better than those in group B(all P＜0.05).In group A,the incidence rate of adverse reaction was 48.15%(13/27),and no serious complication occurred.In group B,the incidence rate of adverse reaction was 88.00%(22/25),and severe drug toxicity was noticed in 5 cases(5/25,20.00%).Conclusion The efficacy and safety of TACE combined with 125I seeds were both better than those of TACE combined with lenvatinib for treating HCC complicated with PVTT.
