乳腺癌保乳治疗(breast conservation therapy,BCT)是早期乳腺癌的标准治疗方式之一,保乳治疗后同侧乳腺肿瘤复发(ipsilateral breast tumor recurrence,IBTR)是临床实践中高度关注的问题.目前已证实手术切缘阳性、缺少放疗或系统治疗是保乳术后IBTR的高危因素,而不同患者预后各异,仍有待进一步开展风险分层评估.如何早期预测及准确诊断保乳术后IBTR是改善患者预后和提高生存率的重要保障.乳腺磁共振成像(magnetic resonance imaging,MRI)具有良好的软组织分辨率和空间分辨率,在保乳术前评估和术后随访中体现出重要的临床价值.本文就MRI在保乳治疗及术后IBTR中的研究现状及进展予以综述.
Breast conservation therapy(BCT)is one of standard treatments for early breast cancer.Ipsilateral breast tumor recurrence(IBTR)after BCT remains a matter of great concern in clinical practice.Positive surgical margins and lack of radiotherapy or systemic therapy have been confirmed to be high-risk factors for IBTR.Due to the prognosis varying from patient to patient,further risk stratification assessment is still needed.Early prediction and accurate diagnosis of IBTR are important guarantees for improving the prognosis and survival rate of patients.Breast magnetic resonance imaging(MRI)has extremely high soft tissue resolution and spatial resolution,which would be of significant clinical value in preoperative evaluation and postoperative follow-up.This article reviewed the research status and progress of MRI in BCT and IBTR.
