概括
在新辅助化疗 (NACT) 后的常规样本放射学 (CSR) 并没有显著减少乳腺癌患者的重复手术,这些患者的完整反应. 常规的CSR使用是可疑的,需要探索替代的业内利率评估工具.
科学领域:
- 在瘤学瘤学.
- 手术病理学手术病理学
- 放射学 放射学是一门学科.
背景情况:
- 新辅助化疗 (NACT) 用于治疗原发性乳腺癌.
- 在NACT后评估手术边缘对于有效治疗至关重要.
- 常规样本放射学 (CSR) 是一种用于在手术内评估边缘的工具.
研究的目的:
- 评估CSR的诊断准确性,以确定NACT后的积极边际.
- 为了确定CSR引导的再切割是否会降低NACT治疗的乳腺癌患者的二次手术率.
- 评估在NACT后获得临床完整反应 (cCR) 的患者中CSR的实用性.
主要方法:
- 在376例乳腺癌患者的回顾性研究中,这些患者在NACT后接受了乳腺保护手术 (BCS).
- 进行CSR以检测边缘透,指导手术内再切割.
- 组织学检查作为边际评估准确性的黄金标准.
主要成果:
- 对于积极的利率,CSR显示了37.3%的灵敏度和85.6%的特异性.
- 企业社会责任的正预测值 (PPV) 为11.3%,负预测值 (NPV) 为96.5%.
- 以CSR为指导的重新切割将次要程序从75减少到37 (NNT=10);在cCR子组中,NNT为34.
结论:
- 以CSR为指导的手术内切割并没有显著减少NACT后cCR患者的二次手术.
- 在NACT之后,企业社会责任的常规应用值得怀疑.
- 建议开发和评估替代的手术内利率评估技术.

Radiological Investigation I: X-ray and CT
299
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
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...
