Abstract:
Objective Todeterminetherelationshipbetweenthetumorvolumeoftheperipherallungadenocarcinomawith maximum diameter≤3cmandlymphnodemetastasis(LNM).Methods TheMSCTmanifestationsof235subjectswhowerediagnosedasperipheral lungadenocarcinomawithmaximumdiameter≤3cm wereretrospectivelyanalyzed.Thesepatientsweregroupedaccordingtodifferent parametersincludingsmokinghistory,differentiation,tumorconsistencyandavailabilityoftumornecrosis.Tumorvolumeandratesof LNMamongthesegroupswerecompared.ROCanalysiswasusedtocalculatethecut-offvalueanddiagnosticaccuracy.Results (1) ThetumorvolumeofLNMgroupwaslargerthanthatofnoLNMgroup,cut-offvaluewas5.5cm3,andAUCwas0.76;(2)Therates ofLNMofthewell,moderate-well,moderate,moderate-poorandpoordifferentiationgroupswere0%,8.7%,17.7%,45.6%and46.7%respectively.Theratesofpuregroundglassopacity(p-GGO),mixedandsolidtumorwere0%,8.3%and29.3%respectively.The ratesofthetumorpresentandabsentofnecrosiswere47.8%,22.0%respectively(P＜0.05).Conclusion Usingthevolumeoftumor on MSCTtopredictLNMisanewnon-invasivewayofassessingLNM,withhighsensitivityandspecificity,whichcouldsupplymore imaginginformationforsurgeonstochoosethewayoflymphnodedissection.
