乳房MRI显著改变了超过一半早期乳腺癌患者的治疗计划,增加了乳房切除率. 大多数变化是适当的,但老年患者 (≥70) 没有增加乳腺切除计划.
科学领域:
- 在瘤学瘤学.
- 放射学 放射学是一门学科.
- 手术规划 手术规划
背景情况:
- 乳腺磁共振成像 (MRI) 越来越多地用于癌症诊断.
- 它对早期乳腺癌治疗计划的影响需要进一步调查.
- 了解其在优化特定患者群体管理中的作用至关重要.
研究的目的:
- 评估手术前乳腺MRI对新诊断的早期乳腺癌治疗计划的影响.
- 在适当的管理方面,确定受益于MRI的患者子组.
- 评估MRI驱动的变化与随后的病理发现的一致性.
主要方法:
- 一项涉及七个中心的多中心前性观察研究.
- 包括患有早期乳腺癌的患者,这些患者的MRI被认为对治疗计划有益.
- 使用手术前对比度增强型MRI,收集数据根据要求的原因,MRI前后治疗计划的变化以及病理学的理由.
主要成果:
- 在387名参与者中,51%的人在MRI后经历了治疗计划的改变,31%的人改变了乳腺手术计划.
- 计划性乳房切除术的比例在MRI后从15%增加到28% (P<0.001).
- 在85%的病例中,根据病理情况,改变手术计划被认为是适当的;然而,在70岁以上的妇女或计划接受新辅助治疗的妇女中,没有观察到乳房切除率的增加.
结论:
- 术前乳腺核磁共振显著影响选择的乳腺癌早期患者的实质比例的手术管理,导致乳腺切除率增加.
- 大多数这些治疗修改被认为是适当的基于病理学.
- 特定的子组,如老年妇女 (≥70岁),可能不会经历MRI后手术计划的变化,建议仔细考虑其在这些人群中的实用性.

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
