三阴性乳腺癌的MRI研究新进展

New progress in MRI diagnosis of triple-negative breast cancer

三阴性乳腺癌是乳腺癌特殊病理亚型,不表达雌激素受体、孕激素受体和人类表皮生长因子受体-2,因此可选择的临床治疗手段不多。该肿瘤侵袭性强,易复发和转移,预后较差。早期诊断和精准评估对该肿瘤的治疗有重要临床价值。MRI因其较高的软组织分辨率、多序列多方位成像特点、动态血流灌注等优势是目前乳腺癌的常用影像学检查方法。近年来MRI对三阴性乳腺癌的诊断和评估有了进一步的发展。本文就此做一综述,旨在提高对该检查的认识。

Triple-negative breast cancer is a special pathological subtype of breast cancer,which does not express estrogen,progesterone receptor and human epidermal growth factor receptor-2,so there are not many options for clinical treatment.The tumor is highly invasive,prone to recurrence and metastasis,and has a poor prognosis.Early diagnosis and accurate assessment have important clinical value in the treatment of this tumor.Due to its high soft tissue resolution,multi-sequence and multi-directional imaging characteristics,and dynamic blood perfusion,MRI is currently a commonly used imaging method for breast cancer.In recent years,MR has further developed in the diagnosis and evaluation of triple-negative breast cancer.This article makes a review on this,aiming to raise awareness of the inspection.
