ABSTRACT
Objective Toexplorethecorrelationbetween MRIcharacteristicsandaxillarylymphnode metastasisofmass-type breastcancer.Methods MRIcharacteristicsandpathologicalresultsofpostoperativeaxillarylymphnode metastasisin187cases withmass-typebreastcancerwereanalyzedretrospectively.Accordingtothenumberoflymphnodemetastases,allofthepatients weredividedintothefourgroupspN0,pN1,pN2andpN3.Thecorrelationbetween MRIsignsand N pathologicalstagesineach groupwereanalyzed.Results Therewere108casesinpN0group,33casesinpN1group,22casesinpN2groupand24casesinpN3 groupI.nthedifferentgroups,therewere15,5,1and1casewithroundmassrespectively;8,1,1and0casewithlobularmasserespectively;85, 27,20and23caseswithirregularmasserespectively.Theshapeswerenotsignificantlydifferentamongthedifferentgroups(P>0.05)I.nthe differentgroups,therewere7,0,1and0casewithclearmarginrespectively;69,14,7and8caseswithirregularmarginrespectively;32,19,14and16caseswithspiculatedmarginrespectively.Themarginsweresignificantlydifferentamongthedifferentgroups(P<0.05)I.nthe differentgroups,therewere55,16,14and18caseswithheterogenousenhancementrespectively;43,14,5and6caseswithringenhancement respectively;3,1,1and0casewithcentralenhancementrespectively;7,2,2and0casewithseptumenhancement.Theenhancement patternswerenotsignificantlydifferentamongthedifferentgroups (P>0.05).ThenumbersofthemasswithtypeⅠ,ⅡandⅢtime-signalcurvesandtheADCvalueswerenotsignificantlydifferentamongthedifferentgroups(P>0.05).Conclusion MRIfeaturesof mass-typebreastcancershavelimitedvalueindeterminingaxillarylymphnodemetastasis.However,thespiculatedmarginofmassis valuableindeterminingaxillarylymphnodemetastasis.
