概括

治疗中期的乳腺MRI参数,包括瘤大小和明显扩散系数 (ADC) 的变化,有效预测局部晚期乳腺癌 (LABC) 中新辅助化疗 (NAC) 的病理完整反应 (pCR). 这些发现可能有助于个性化NAC战略.

科学领域:

在瘤学瘤学.
放射学放射学是一门学科.
医疗成像医学成像

背景情况:

局部晚期乳腺癌 (LABC) 需要有效的新辅助化疗 (NAC).
预测早期的治疗反应对于优化患者的治疗结果至关重要.
中期治疗评估可以指导治疗决策.

研究的目的:

评估治疗中期乳腺MRI参数对病理完整反应 (pCR) 的预测性表现.
确定尺寸和功能性MRI指标,预测在接受NAC的LABC患者中的pCR.

主要方法:

对接受NAC.的65名LABC患者的回顾性分析.
从NAC前和中部扫描中计算定量MRI参数 (例如,直径,体积,ADC,Epeak的百分比变化).
后勤回归和ROC分析以识别和比较PCR预测器.

主要成果:

在29%的患者中实现了pCR.
在pCR患者中观察到瘤大小和Epeak显著减少,ADC值增加.
在治疗中期,最大直径的百分比变化 (>60%) 和ADC值的百分比变化 (≥32%) 是PCR的独立预测因素.

结论:

治疗中期的MRI生物标志物,特别是最大直径的百分比变化和ADC值的百分比变化,是pCR的有效早期预测因素.
这些MRI发现可能会在LABC的NAC期间支持个性化治疗策略.

Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
