ER阴性原发性乳腺癌HER-2过表达与X线表现及临床特征相关分析

目的：探讨雌激素受体阴性(ER-)乳腺癌患者中,人类表皮生长因子受体-2过表达(H ER-2+)与 X线及临床病理特征的关系。方法收集资料完整的ER-乳腺癌患者190例,其中 HER-2+患者78例,HER-2无过表达(HER-2-)患者112例,比较2组患者的 X线表现和临床病理特征。结果 HER-2+组与 HER-2-组比较,年龄分布具有显著性差异(P<0.001),HER-2+多见于高年龄患者(>60岁)；HER-2+组更多伴有淋巴结转移(P=0.011)。X线表现方面,单纯钙化多见于 HER-2+组(P=0.000),单纯肿块多见于 HER-2-组(P<0.001)。HER-2+组多为分叶状肿块(P<0.001),毛刺多见(P=0.000),而 HER-2-组多为圆形肿块(P=0.014),边缘光滑(P=0.000)。钙化表现上,HER-2+组更多表现为恶性钙化(P=0.000)。结论 ER-乳腺癌 HER-2具有一定的临床及 X线特征,可以为临床医师在乳腺癌个体化诊疗中提供重要参考依据。

Estrogen receptor negative primary breast carcinoma:correlation of human epidermal growth factor receptor type 2 overexpression with mammography and clinic features

Objective To explore the correlation of human epidermal growth factor receptor type 2 overexpression (HER-2+)and mammographic and clinical features in breast cancers with estrogen receptor negative expression (ER-).Methods 190 cases of ER-breast cancer were included in this study.There were 78 cases with HER-2+,and 112 cases with HER-2-.The pathological and mammographic features were compared between the two groups.Results Compared with the HER-2- group,the HER-2+ group was more in older women (P<0.001)and more likely to have a lymphonodus metastasis (P=0.011).For mammographic manifesta-tions,pure calcifications were more detected in the HER-2+ group (P=0.000),and pure masses were more detected in the HER-2-group (P<0.001).The HER-2+ group was more likely showed as a lobulated mass (P<0.001),and with spiculated margin (P=0.000). However,the HER-2- group was more likely showed as a round mass (P=0.014),and with smooth margin (P=0.000).The cal-cifications of HER-2+ group were more likely showed as malignancy calcifications (P=0.000).Conclusion HER-2 overexpression breast cancer with ER- has some mammographic and clinical features,which is helpful for individual diagnosis and treatment.
