To explore the relationship between the imaging features of ultrasonography and thermal tomography and molecular subtypes of breast cancer.
404 female breast cancer patients with complete imaging data and pathological findings from January 2014 to June 2017 were reviewed in the West China Hospital of Sichuan University. Breast cancer pathological molecules were classified into Luminal A like type, Luminal B like type, human epidermal growth receptor-2 (HER-2) overexpression type and Basal like type according to the expression of various immune markers. The correlation of ultrasonographic BI-RADS signs, thermal tomography characteristics and immunohistochemical results of breast cancer was analyzed.
Breast cancer lesions with regular morphology, sharp margins, and enhanced posterior echo were more common in Basal like type; Microcalcification was more likely tend to appear in HER-2 expression breast cancer than other subtypes; The q-r curve of Luminal A like breast cancer was nearly 30°, and that was more common between 30°and 45° of HER-2 expression and Basal like breast cancer;The ratio of vertical and horizontal ≥1 of tumors and limited lymph node metastasis could not be used for distinguishing between different subtypes.
Different molecular subtypes of breast cancer may behave routine ultrasound and thermal tomography imaging features.
探讨超声成像特征、热层析成像与乳腺癌分子亚型之间的关系。
回顾性分析2014年1月至2017年6月在四川大学华西医院就诊的404例有完整影像学资料及病理结果的女性乳腺癌患者。根据各种免疫标志物的表达情况,将乳腺癌病理分子分为Luminal A样型、Luminal B样型、人表皮生长因子受体2(HER-2)过表达型和基底样型。分析乳腺癌超声BI-RADS征象、热层析成像特征与免疫组化结果的相关性。
形态规则、边界清晰、后方回声增强的乳腺癌病灶在基底样型中更为常见;微钙化在HER-2表达型乳腺癌中比其他亚型更易出现;Luminal A样型乳腺癌的q-r曲线接近30°,HER-2表达型和基底样型乳腺癌的q-r曲线多在30°至45°之间;肿瘤纵横比≥1及局限性淋巴结转移不能用于区分不同亚型。
乳腺癌不同分子亚型可能具有不同的常规超声及热层析成像特征。
