RESUMO
Objective ToinvestigatethecorrelationbetweenCTimagingfindingsoflungadenocarcinomaandepidermalgrowth factorreceptor(EGFR)genemutation.Methods Theclinicaldataof150lungadenocarcinomapatientsinthehospitalfrom October 2015toOctober2017werecollectedretrospectively.AccordingtotheEGFRgenemutation,thepatientsweredividedintononeffectivemutation group (n=78)andeffective mutationgroup (n=72).Univariateanalysisand multivariate L o g istic regression modelwereperformed toexplorethepredictionsignsofeffectiveEGFRgenemutationinlungadenocarcinoma.Results Univariateanalysisshowedthatthe proportionsoffemalepatients,smokinghistory,CTfindingsofspiculesign,necroticsign,pleuralindentationandnonfibrosisin theeffectivemutationgroupweresignificantlyhigherthanthoseinnoneffectivemutationgroup(P<0.05).However,therewereno significantdifferencesbetweenthesetwogroupsinage,diameteroflesions,locationoflesions,densityoflesions,lobulatedsign, cavitation sign ,air bronchogram and pleuralthickening sign (P>0 .05 ).M ultivariate L o g istic regression analysis showed thatfemale (OR=2.612),spiculesign(OR=2.476),necroticsign(OR=2.846),pleuralindentation(OR=2.221)andnonfibrosis(OR=2.476)were independentpredictorsofeffectiveEGFRgenemutationinlungadenocarcinoma(P<0.05).Conclusion FemaleandlungadenocarcinomaCT findingsofspiculesign,necroticsign,pleuralindentationandnonfibrosisarerelatedtoEGFRgenemutation,whichisofgreatsignificanceto distinguishingwildtypefrom mutanttypeofEGFRgeneandguidingtheclinicaltreatment.
