ExpressionandClinicalSignificanceofJunDinMolecularSubtypesof InvasiveBreastCarcinoma / 中山大学学报(医学科学版)

ABSTRACT

@#【Objective】ToinvestigatetheexpressionandclinicalsignificanceofJunDinmolecularsubtypesofinva⁃ sivebreastcarcinoma，benignandmalignantbreastlesions.【Methods】Immunohistochemicalexaminationwasperformed for160patientswithinvasivebreastcarcinoma，191patientswithbreastintraductalproliferativelesionsand20patients withnormalbreasttissue.【Results】①ComparisonwithothersubtypesshowedthattheexpressionofJunDwassignificantly increasedinTBNCsubtype（P＜0.05）anddifferencesbetweenothersubtypeswerenotstatisticallysignificant（P＞0.05） . ②TheexpressionofJunDininvasivebreastcarcinomawaslowerthanthatinbreastintraductalproliferativelesionsand normalbreasttissuse（P <0.01） .③Basedonimmunohistochemicalstaining，highpositiveexpressionrateofJunDwas associatedwithlowhistologicalgrade（P <0.01）.ThereisnocorrelationbetweenJunDandtumordiameter，age，lymph nodes，ER，PRandhistologicalgrade（P >0.05） .【Conclusions】TheexpressionofJunDwassignificantlyincreasedin TBNCsubtype.TostudytheexpressionofJunDinTBNCsubtypeofinvasivebreastcarcinomamayprovideanevaluation intargetedtreatment.ThedifferentexpressionofJunDinbenignandmalignantbreastlesionsmaybehelpfulfortheir differentialdiagnosis.
