Abstract:
Objective ToevaluatetheefficacyandsafetyofCT-guidedmicrowaveablation (MWA)forstageIVlungcanceraccompanied withcontrolledsingleintracranialmetastasis.Methods From November2011toOctober2016,78patientsinourhospitaldiagnosed withstageIVnon-smallcelllungcanceraccompaniedwithcontrolledsingleintracranialmetastasiswerestudied.Patientsweredividedintotwo groupsaccordingtowhethertheywerewillingtoacceptlocalMWAtreatmentornot:thegeneralgroup (groupA)with42cases, and MWAgroup(groupB)with36cases.Aftertheintracranialmetastasiswascontrolled,patientsingroupAweretreatedwithGP regimenforsimplechemotherapy,whilepatientsingroupB weretreatedwithlocalMWAcombinedwithGPregimen(gemcitabine combinedwithcisplatin).Allthepatientswerefollowed-upevery3monthsafterthesurgerytoassesstheefficacyandsafetyofthe correspondingtreatment.Thedeadlineofthefollow-upwasJune2017orwhenthetumorrestarteditsdevelopment.Results Thesuccessrateof theMWAofthe39lesionsinthe36patientsingroupBwas100%.TheKaplan-Meiersurvivalanalysisofthefollow-updataofthe twogroupsshowedthattheaverageprogressionfreesurvival(PFS)ofgroupA was(9.9 ± 0.8)monthsandthemedianPFSwas (8.0±0.5)months,whilethePFSofgroupB was (14.1±1.1)monthsandthe medianPFS was (15.0±1.5)months.The Log Rank testshowedthatχ2=8.780andP=0.03<0.05,whichreflectedthatthereweresignificantdifferencesinsurvivaltimebetweenthe twogroups.Theoverallsurvival(OS)ofgroupA was(20.5±1.1)months,andthemedianOSwas(21.0±1.3)months.TheOSof group B was (24.1±1.5)months,andthe median OS was (25.0±3.6)months.The Log Rank testshowedthat χ2=10.57and P=0.02<0.05, whichprovedthattheOSdifferencesbetweenthetwogroupshadstatisticalsignificance.ThemainadverseeffectsofMWA werepain,pleural effusion,pneumothorax,hemoptysis,infectionandsoon.There werenoseriouslife-threateningcomplicationsingroupB.Conclusion LocalMWAtreatmentforstageⅣnon-smallcelllungcancer withcontrolledsingleintracranialmetastasisisasafeandeffective method.Itisworthyofporularizing.
