ABSTRACT
Objective Toinvestigatetheshort-termefficacyoftranscatheterarterialchemoembolization(TACE)combinedwith microwaveablation (MWA;TACE-MWA)inthetreatmentofmultinodularhepatocellularcarcinoma (HCC).Methods 58patients withmultinodularHCCtreatedintheinterventionalmedicinecenterfromJanuary2015toJanuary2017wereincludedingradeAor B.34cases(groupA)receivedTACEand24cases(groupB)underwentTACE-MWAtherapy.Theshort-termefficacywasevaluatedbyfollow-upandanalysisofthetimetoprogression (TTP),localrecurrencerate,newlesionrate,andpostoperativecomplicationsinboth groups.Results TheTTPinthetwogroupswas38-240 (106.2±63.1)daysand90-630 (328.5±178.8)daysrespectively.The incidenceofpostoperativecomplicationsintwogroupswas2.9% (1/34)and4.2% (1/24)respectivelyI.ngroupA,thelocalrecurrenceratewas 52.9% (18/34)andthenewfocusratewas76% (26/34);inthegroupB,thelocalrecurrenceratewas8.3% (2/24)andthenewfocusratewas 66.7% (16/24).Thedifferenceoflocalrecurrenceratebetweenthetwogroupswasstatisticallysignificant(P<0.05),whiletheincidenceofnew lesionwasnotsignificantlydifferent (P>0.05).Conclusion TACE-MWAissafeandeffectiveinthetreatmentofmultinodular HCC.ComparingwithtraditionalTACEtreatment,TACE-MWAcansignificantlyimprovedTTPandlocalcontrolrate.
