ABSTRACT
Objective Toimprovethepreoperativediagnosisoflungadenocarcinomaaccordingtotherelationshipbetweenthevisceralpleural invasion(VPI)andtheCTfeatures.Methods TheCTfeaturesandthepathologicalmanifestationsof351lungadenocarcinomasconfirmedby surgicalpathologywereretrospectivelyanalyzed.TworadiologistsindependentlyevaluatedtheCTfeatures,includingthelocationand maximumdiameterofthelesion,theminimumdistancefromthelesiontothepleura(DLP)inthree-dimensionalreconstructionimageandthe relationofthelesiontotheadjacentpleura(RAP).TheRAPwasdescribedas5types(1)nocontactofthethelesionwiththepleura,(2)aline betweenthelesionandthepleurawithoutretractionoftheinvolvedpleura,(3)thelesiontightlyclosedtothepleurawithouttypical pleuraretraction,(4)oneormorelinearstrandsradiatedfromthelesiontothepleuralsurfacewithpleuralretraction,(5)broadcontactofthe lesionandpleurawiththecontactsurfaceoflesionover50% withpleuralretraction.Anexperiencedpathologistevaluatedthehistopathological patternsaccordingtothe7thEditionoftheTNMclassificationforlungcancer(PL0-PL2).AndthePL1andPL2weredescribed as VPI (+)group ,meanwhile the PL0 was as the VPI (-)group .Univariate analysis such as t test,χ 2 or One-W ay analysis of variance was performedtoidentifytheindependentpredictorsinpredictingVPI.Results Significantdifferenceswerefoundinpatientage,lesionlocation, maximumdiameter,andRAPbetweenVPI(+)andVPI(-)groups(P<0.05).Conclusion Whenthepatientwithlungadenocarcinomais over60yearsold,withthelesiondiameterover2.3cm,thepossibilityofvisceralpleuralinvasionwillbeconsideredaccordingtothe relationshipofthelesionandtheadjacentpleura(abuttingpleuralorpleuralindentation).
