概括
在中度低分离全乳腺放射治疗后,瘤床增强会增加乳腺疼痛和皮肤炎等急性毒性. 电子提升没有显示任何负面的化品效应,但光子提升却没有.
科学领域:
- 在瘤学瘤学.
- 辐射瘤学 辐射瘤学
- 临床瘤学临床瘤学
背景情况:
- 随机试验表明,瘤床增强改善了全乳腺放射治疗 (WBRT) 后的局部控制.
- 然而,人们对与增强剂相关的急性和晚期毒性增加存在担忧.
- 有限的现实世界数据存在于中度低分离WBRT (MH-WBRT) 后瘤床增强剂的毒性.
研究的目的:
- 为了评估瘤床增强后的急性毒性和化品结果,在一个大型前性队列中进行MH-WBRT.
- 评估MH-WBRT后的增强利用的现实世界临床实践.
主要方法:
- 在30个中心 (2012年1月至2023年11月) 预计将在没有区域节点辐射的情况下接受辅助MH-WBRT的女性 (n=11,753) 的招生.
- 通过标准化表格收集数据,用于患者,医生和物理学家的评估.
- 通过复合变量定义的严重毒性;在1年后获得的cosmesis;用于分析的多变量模型.
主要成果:
- 分别在49.0%和22.1%的患者中使用了光子或电子提升剂;28.9%没有得到提升剂.
- 光子和电子都会显著增加急性毒性,包括乳腺疼痛和2级+皮肤炎 (p<0.001).
- 一年后,电子推进与公平/贫穷的宇宙没有关联;光子推进的关联不清楚 (OR 1.30).
结论:
- 现实数据显示,MH-WBRT后的瘤床增强 (电子或光子) 与急性乳腺疼痛和皮肤炎的增加有关.
- 电子推进并没有对一年的宇宙产生负面影响,但光子推进的影响仍然不确定.
- 调查结果有助于就MH-WBRT后提升利用的好处和风险进行共享决策.

Prevention of Further Absorption of Poison
In cases of acute poisoning, the primary objective is to prevent further absorption of the toxic substance into the body. Immediate interventions using various decontamination techniques targeting the gastrointestinal (GI) tract can achieve this. Decontamination is crucial to prevent poison from entering the systemic circulation, which involves washing affected areas with water and mild soap and removing contaminated clothing. Once external decontamination is done, attention must be turned to...
Pharmaceutical Poisoning: Treatment Strategies
Treatment strategies for poisoning are a critical aspect of emergency medicine, focusing on preventing the absorption of toxins and enhancing their elimination. When a poisoning incident occurs, the first response is to halt exposure and decontaminate the patient, particularly through gastrointestinal (GI) methods if the poison was ingested.Gastrointestinal Decontamination Techniques:Activated charcoal is the cornerstone of GI decontamination. It works through adsorption, binding the toxin to...
Healing II: Complications
Complications during healing arise when tissue repair is altered by local or systemic factors. These changes involve abnormal collagen deposition, altered biomechanics, and reduced vascular supply, impairing restoration of normal structure and function.Loss of FunctionScar tissue differs significantly from the original tissue it replaces. In the skin, fibrosis lacks adnexal structures such as hair follicles, sebaceous glands, and sweat glands. Their absence reduces tactile sensitivity, impairs...
