- Abstract: Objective To investigate the roles of miR-155 and miR-23b in the differential diagnosis of idiopathic granulomatous mastitis(IGM)and breast cancer(BC).Methods A total of 32 patients with IGM(the ICM group)and 40 patients with BC(the BC group)admitted to our hospital from October 2018 to November 2021 were selected.All patients were confirmed by biopsy.In addition,33 healthy women were included as the control group.The clinical data of patients were compared.The expression levels of serum miRNAs were detected by real-time fluorescence quantitative PCR.The diagnostic value of serum miR-155 and miR-23b for IGM and BC was evaluated by receiver operating characteristic(ROC)curve.The Pearson correlation coefficient method was used to evaluate the correlation.Results There were statistically significant differences in the levels of CRP,WBC,Hb,Hct,CA19-9,CA15-3 and CA125 among the three groups(P<0.05).The expression levels of serum miR-155,miR-16-5p,miR-21-5p,miR-210-3p,miR-222-3p and miR-29c-3p in the IGM group were higher than those in the control group(P<0.001),and the expression level of serum miR-23b was lower than that in the control group(P<0.001).The expression levels of the above miRNAs of serum in the BC group were higher than those in the control group(P<0.001).The expression level of serum miR-155 in the BC group was lower than that in the IGM group(P<0.001),and the expression level of serum miR-23b was higher than that in the IGM group(P<0.001).The area under the ROC curve(AUC)for the differential diagnosis of IGM and BC by serum miR-155 and miR-23b levels were 0.722(95%CI:0.601 to 0.843)and 0.765(95%CI:0.657 to 0.874),respectively,with sensitivity of 81.00%and 77.50%,and specificity of 65.00%and 59.40%,respectively.The AUC of combined differential diagnosis was 0.869(95%CI:0.786 to 0.951),and the sensitivity and specificity were 84.10%and 92.50%,respectively.Serum miR-155 was positively correlated with WBC and CRP levels in the IGM group(P<0.05),while serum miR-23b was negatively correlated with WBC and CRP levels(P<0.05).Conclusion Serum miR-155 and miR-23b are helpful in distinguishing IGM from BC,and can be used as targets for early differential diagnosis of IGM and BC.
