概括
主要运动皮层中的大脑转移 (BMs) 显著增加了患者的发作风险. 建议对这种人群的预防性抗发作药物进行进一步的研究.
科学领域:
- 神经学 神经学
- 在瘤学瘤学.
- 神经瘤学神经瘤学
背景情况:
- 发作是大脑转移 (BMs) 的常见并发症,影响患者的生活质量.
- 与BMs的位置相关的发作的特定风险尚未得到充分理解.
- 非瘤学文献表明,初级运动皮层干扰与发作倾向之间存在联系.
研究的目的:
- 评估位于主要运动皮质的大脑转移是否与其他大脑区域的BM相比,与发作风险更高有关.
- 研究大脑转移的位置和患者中发作的发生之间的关系.
主要方法:
- 在2003年至2022年期间诊断出脑转移的3043名患者进行了回顾性队列研究.
- 共变量包括人口,临床,瘤和与治疗相关的因素.
- 统计分析利用单变量/多变量物流和细色和灰色竞争风险回归来评估与初级运动皮层BMs相关的发作风险.
主要成果:
- 患有原发性运动皮质BM的患者在诊断时 (OR2.87) 和随后 (HR1.95) 显著增加了发作的风险.
- 在患有新肌肉瘤的患者中,那些主要运动皮层参与的患者更有可能经历发作 (HR 2.11).
- 18.7%的患者在初级运动皮层有BMs,而没有的患者是81.3%.
结论:
- 位于主要运动皮质的大脑转移与发作风险增加有关.
- 根据这些回顾性数据,不建议使用常规预防性抗发作药物.
- 专门的临床试验调查预防性抗发作药物用于原发动性皮质BMs的患者是有必要的.

The cerebral cortex, the brain's outermost layer, is pivotal in processing complex cognitive tasks, emotions, and various sensory inputs and executing voluntary motor activities. This intricate structure is divided into three primary functional areas: the motor areas, sensory areas, and association areas.
Motor Areas
The motor areas located in the frontal lobe are central to controlling voluntary movements. This region is further subdivided into the primary motor cortex and the premotor cortex....

The somatosensory cortex in the parietal lobes is crucial for interpreting sensory data such as touch, temperature, and proprioception. The somatosensory cortex, situated in the parietal lobes, plays a vital role in interpreting sensory information like touch, temperature, and proprioception—awareness of body position. This specialized brain region features an organized structure wherein neurons at the top primarily process sensations originating from the lower body. In contrast, those at...
