概括
在乳腺癌 (BC) 中,新辅助化疗 (NAC) 反应显示出成像和病理学之间的中等一致性. 虽然病理完整反应 (pCR) 表明更好的生存率,但放射学和组织病理学模式都不能可靠地预测整体或无病生存率.
科学领域:
- 在瘤学瘤学.
- 放射学 放射学是一门学科.
- 病理学 病理学 病理学
背景情况:
- 新辅助化疗 (NAC) 对乳腺癌 (BC) 的反应对于治疗计划和生存至关重要.
- 响应模式包括同心收缩 (CS),非同心收缩 (非CS) 和完整响应.
- 放射学和组织病理学评估用于评估NAC后的瘤反应.
研究的目的:
- 为了评估NAC后BC患者的组织病理学和放射学反应模式之间的相关性.
- 评估这些反应模式对整体存活率 (OS) 和无病存活率 (DFS) 的影响.
主要方法:
- 对168名接受NAC治疗的BC患者 (2018-2022) 的回顾性分析.
- 瘤反应通过MRI (放射学) 和术后组织病理学进行评估.
- 使用kappa统计分析的一致性;使用Kaplan-Meier方法的生存率.
主要成果:
- 放射学和组织病理学评估之间适度一致 (κ:0.439).
- 放射性评估准确地确定了64%的CS,50%的非CS和74%的pCR病例.
- 瘤分子亚型与响应模式有显著的相关性;在TN,HER2丰富和光线B-HER2 ((+) 亚型中,pCR率更高.
- 在响应模式和OS或DFS之间没有发现显著的相关性,尽管pCR趋向于更好的结果.
结论:
- 在NAC后的放射学和组织病理学反应模式之间存在适度的一致性,但这些差异突显了仅仅成像的局限性.
- 观察到的反应模式与预后没有显著的相关性.
- 达到病理完整反应 (pCR) 与生存率的提高有关,但单独的反应模式不足以预测生存率.

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...

Cancer Survival Analysis
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...
