概括

本案例研究强调了与小细胞肺癌和大脑转移患者的tarlatamab治疗相关的潜在神经学副作用,包括大脑缩和白脑病变.

科学领域:

在瘤学瘤学.
神经学神经学
辐射疗法辐射疗法

背景情况:

扩散阶段的小细胞肺癌 (SCLC) 提出了重大治疗挑战,通常涉及大脑转移.
标准治疗包括化疗,免疫疗法和放射疗法,对耐火性疾病的选择有限.

研究的目的:

报告一个罕见的早期脑缩和白脑病变的病例,该病例发生在SCLC脑转移患者中,该患者接受了tarlatamab治疗.
为了调查与tarlatamab结合全脑放射治疗相关的潜在神经学不良事件.

主要方法:

一个74岁的女性病例报告,患有广泛的SCLC和大脑转移.
综述治疗史,包括卡博普拉丁,埃托波西德,阿特佐利祖马布,阿姆鲁比辛,诺吉特坎,立体辐射疗法,全脑辐射疗法和塔拉塔马布.
分析神经成像 (MRI,FLAIR) 和tarlatamab管理后的临床反应.

主要成果:

患者在治疗tarlatamab后出现了迷失方向,快速脑缩,心室扩大和周心室高强度.
转移性病变显示缩小,但神经症状没有改善德克萨米他.
观察到的神经事件被归因于全脑放射治疗和tarlatamab的联合作用.

结论:

塔拉塔马布,特别是与全脑放射治疗一起使用,可能会在脑转移患者中造成严重的神经毒性风险.
接受tarlatamab的大脑转移的患者需要对潜在的不良事件进行密切的神经监测.
需要进一步的研究来理解和减轻新型SCLC疗法的神经毒性风险.

Brain Abscess l: Introduction

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial...

Hepatic Encephalopathy

Hepatic Encephalopathy

DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic...
