Abstract:
Objective To explore the relationship between the characteristics of X-ray and magnetic resonance imaging(MRI) and the expression level of estrogen receptor(ER),progesterone receptor(PR)and human epithelial factor receptor 2(HER2)in breast cancer patients.Methods 108 cases of breast cancer patients in the first 74 Hospital of the PLA from January 2013 to Janu-ary 2017 were selected as the research object.Clinical,pathological and imaging data of patients were collected.All patients were ex-amined by X-ray and MRI after admission.The expressions of ER,PR and HER2 in cancer cells were detected by immunohisto-chemical staining.Results The expression of ER,PR and HER2 was positive in 73 cases(67.59%),63 cases(58.33%)and 43 ca-ses(39.81%),respectively.The positive rate of HER2 in patients with calcification was higher than that in patients without calcifi-cation(P<0.05).The positive rate of PR in patients with calcification along the duct was lower than that in patients of whom the calcification was not along the duct,and the positive rate of PR in patients with glandular or mixed density was higher than that in patients with structural disorder(P< 0.05).The positive rate of ER was higher in patients with calcification,mass,spiculation signs,glandular or mixed density(P<0.05).There were significant differences in the positive rate of HER2 between patients with different shapes and different enhancement modes(P<0.05),and there was a significant difference in the positive rate of PR be-tween patients with different enhancement modes(P<0.05).Calcification displayed by X-ray mammography was positively corre-lated with HER2,calcification along the duct was negatively correlated with the expression of PR,calcification with mass was posi-tively correlated with ER and negatively correlated with PR,spiculation sign was positively correlated with ER,and structural disor-der was negatively correlated with ER and PR.Mass type and inhomogeneous enhancement of MRI signs were negatively correlated with HER2,irregular shape was positively correlated with HER2,and inhomogeneous enhancement was positively correlated with PR (r = 0 .363 ,- 0 .375 ,0 .368 ,- 0 .326 ,0 .426 ,- 0 .489 ,- 0 .373 ,- 0 .468 ,- 0 .403 ,0 .391 ,0 .425 ;P < 0 .05) .Conclusion There is a correlation of signs of X‐ray mammography and MRI signs with the expression of ER ,PR and HER2 .Imaging changes can predict the expression of some biological factors of breast cancer ,which is related to hormones ,chemotherapy sensitivity and the prognosis of patients.
