Research paper thumbnail of The safety and efficacy of transarterial lipiodolized chemoembolization with Embospheres in treatment of hepatocellular carcinoma

From May 2010 to March 2014, 110 inoperable HCC patients were divided into two groups in this retrospective study. The Embo-TACE group received lipiodol and a chemotherapeutic agent emulsion followed by Embospheres. The cTACE group received conventional TACE (lipiodol and chemotherapeutic agent emulsion) followed by gelatin-sponge pellets. Time to progression (TTP), overall survival (OS), overall response rate (ORR), and safety were compared. A multivariate analysis of the factors affecting survival was also conducted. The median TTP and OS in the Embo-TACE group were significantly longer than in the cTACE group (7.0 months, 95% CI: 4.285-9.715 vs. 5.4 months, 95% CI: 3.619-7.181, P = 0.035; 15 months, 95% CI: 12.374-17.626 months vs. 12 months 95% CI: 10.434-13.566 months, P = 0.032). Seven days after the firs...
