免疫检查点抑制剂可能导致罕见但严重的肠壁损伤,即使在癌症缓解后. 这份病例报告强调了在治疗结直肠癌时使用 pembrolizumab 后发生自发结肠切割的风险.
科学领域:
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
- 胃肠病学 胃肠病学
背景情况:
- 免疫检查点抑制剂 (ICI) 在微卫星不稳定性高 (MSI-H) 的结直肠癌中表现出显著的疗效.
- 对ICI的完整反应可能会导致尚未完全理解的长期组织影响.
- 目前的成像可能无法检测免疫疗法诱导的肠壁脆弱性.
研究的目的:
- 报告一种新型病例,即在对 pembrolizumab 的病理完整反应后发生了自发性结肠切割.
- 突出目前成像在评估免疫疗法诱导的组织损伤的局限性.
- 强调需要增加外科意识,并在新辅助性ICI治疗的背景下重新评估外科规划.
主要方法:
- 一个患有高MSI结直肠癌的患者的病例报告,接受了 pembrolizumab治疗.
- 对临床表现,放射学发现和病理结果的审查.
- 讨论免疫媒介组织重塑及其结构后果.
主要成果:
- 患者获得了对 pembrolizumab.com的病理完整反应.
- 尽管有放射性疾病的解决,在瘤部位发生了自发的结肠切割.
- 这一事件被归因于深刻的免疫媒介组织重塑,表明结构性衰竭.
结论:
- 在ICI治疗后瘤回归并不能保证器官功能恢复.
- 延迟的结构性毒性,如肠壁脆弱性和切断,是一个关键问题.
- 为了管理这种风险,需要多学科的警,改进的成像,生物标志物开发和修改的手术规划.
