Combination of percutaneous radiofrequency ablation with transarterial chemoembolization for hepatocellular carcinoma： observation of clinical effects

Objective:Toobservetheclinicaleffectofradiofrequencyablation(RFA)combinedwithtranscatheterarterialchemoembolization(TACE)foradvancedhepatocellularcarcinoma(HCC).Methods:Atotalof92casesofadvancedprimarylivercancerunderwentTACEandRFAtreatmentfromJune2005to2011attheDepartmentofHepatobiliarySurgery,theFirstAffiliatedHospitalofBengbuMedicalCollege.Atotalof88caseswithcompleteclinicaltreatmentandfollow-updataweredividedintotwogroups:43patientstreatedwithTACE(TACEgroup)and45patientsthatreceivedTACEcombinedwithRFAtreatment(TACE+RFAgroup).Afterclinicaldataassessment,tumorsizeandsurvivalstatuswerenotsignificantlydifferentbetweenthegroupsasdeterminedbystratifiedanalysis.Results:Beforeandaftersurgery,spiralCTradiographyandcolorcomparisonobservedablationconditions.Thetumornecrosisratesaftertreatment(CR+PR)were67.4%(29/43)and91.1%(41/45)fortheTACEandcombinedtreatmentgroups,respectively,andthedifferencewasstatisticallysignificant(P<0.05).ThequalityoflifewassignificantlyimprovedforpatientsundergoingTACE+RFAcomparedwiththecontrolgroup.SurvivaldurationwasnotsignificantlydifferentinpatientsundergoingTACE+RFAcomparedwiththecontrolgroup.Conclusions:Inthisstudy,theeffectofRFAcombinedwithTACEtreatmentwasbetterthanTACEaloneintreatingadvancedHCC.
