癌症治疗引起的严重免疫媒介性大肠炎 (IMC) 呈现出各种症状和发现. 活检至关重要,因为即使在看起来正常的内镜中也可能存在炎症,以指导准确的诊断和管理.
科学领域:
- 在瘤学瘤学.
- 胃肠病学 胃肠病学
- 免疫学 免疫学 免疫学
背景情况:
- 免疫检查点抑制剂 (ICI) 已经改变了癌症治疗,但可以导致严重的免疫媒介性结肠炎 (IMC).
- 关于严重的 (3-4级) IMC,特别是其临床,内镜和组织学特征的数据仍然有限.
- 了解严重的IMC对于在癌症患者中管理这种可能危及生命的不良事件至关重要.
研究的目的:
- 综合分析严重 (3-4级) 免疫媒介性大肠炎 (IMC) 的临床,内镜和组织学特征.
- 研究严重IMC患者的临床症状,内镜检测结果和组织病理学结果之间的相关性.
- 突出诊断挑战,并为严重的IMC提供信息管理策略.
主要方法:
- 一个多中心的,回顾性观察性研究,涉及成年患者的固体瘤和3-4级IMC需要住院和全身治疗.
- 系统地收集和分析临床数据,内镜检查结果 (使用梅奥和UCEIS指数),以及组织学特征.
- 统计分析以评估临床,内镜和组织学参数之间的相关性.
主要成果:
- 腹是普遍存在的 (平均每天8次排便);腹痛和直肠出血也很常见.
- 内镜检查结果包括血管模式损失 (80%) 和粘膜病变 (69%),其中69%的梅奥得分≥2.2.
- 组织病理学发现了85%的异常,包括密封炎 (50%) 和淋巴细胞透 (48%); 72%的正常内镜检查的患者有组织性炎症.
结论:
- 严重的IMC表现出异质的临床,内镜和组织学特征,具有有限的域间相关性.
- 内镜检查结果通常是性和炎症性,但即使在内镜不活跃的疾病中也可能存在组织学异常.
- 在怀疑IMC病例时,活检是必不可少的,并且需要验证的多维评估工具来进行准确的诊断和管理.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
