概括
术内放射疗法 (IORT) 与外辐射疗法 (EBRT) 相比,在手术后大脑转移 (BMs) 的全身疗法 (CTX) 的时间显著缩短. 这使得癌症治疗的启动速度更快,住院时间更短.
科学领域:
- 神经瘤学神经瘤学
- 手术瘤学手术瘤学
- 辐射瘤学 辐射瘤学
背景情况:
- 由于伤口愈合或放射治疗,手术后的大脑转移 (BM) 患者的延迟全身疗法 (CTX) 可能会影响cologic结果.
- 术内放射疗法 (IORT) 是一种新兴的神经瘤技术,与传统的外部光束放射疗法 (EBRT) 相比,它可以减少整体治疗时间.
研究的目的:
- 在手术切除后接受IORT或辅助EBRT的大脑转移 (BMs) 的患者中,比较过渡到全身治疗 (CTX) 的时间.
- 评估IORT与EBRT对手术到开始全身瘤治疗的时间间隔的影响.
主要方法:
- 对99名为BMs进行手术的患者进行了回顾性图表审查分析.
- 根据机构协议,患者接受了IORT (40名患者) 或辅助EBRT (59名患者).
- 从手术到CTX启动的时间和IORT和EBRT组之间的住院总时间的比较.
主要成果:
- 与接受EBRT (65.4天) 患者相比,接受IORT的患者在CTX启动之前的间隔显著较短 (32.3天) (P <.001).
- 在IORT组 (9.5天) 和EBRT组 (20.2天) 中,住院至CTX启动的时间明显较短 (P < .001).
- 在比较从最后一个EBRT分数到CTX的间隔与IORT到CTX的间隔时,没有观察到CTX的时间有显著差异 (P = .52).
结论:
- 与传统的辅助外部束辐射疗法 (EBRT) 相比,手术内放射疗法 (IORT) 促进了对脑转移 (BM) 患者更快地过渡到全身瘤治疗.
- 在手术切除BMs后,IORT可能在加快全面癌症治疗方面提供优势.

01:29Drug Delivery: Parenteral Route
The parenteral route is a critical method of drug administration. It delivers compounds directly into the systemic circulation and bypasses the gastrointestinal tract. This approach is particularly advantageous for drugs that exhibit poor absorption or instability when administered orally.
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...

01:14Brain Imaging
Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).
