概括
免疫检查点抑制剂 (ICI) 重试对食道状细胞癌 (ESCC) 患者有前途,这些患者在初始治疗中进展. 这种方法可能会为生存带来好处,并提供良好的安全性,特别是对于具有获得性耐药性的患者.
科学领域:
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
- 胃肠道癌症 胃肠道癌症
背景情况:
- 免疫检查点抑制剂 (ICI) 广泛用于癌症治疗,但许多患者患病进展.
- 对于患有晚期食道状细胞癌 (ESCC) 并且在ICI上进展的患者,存在有限的治疗选择.
- 关于ICI重新挑战ESCC中的有效性和安全性的数据很少.
研究的目的:
- 评估免疫检查点抑制剂 (ICI) 在晚期食道状细胞癌 (ESCC) 患者的疗效和安全性.
- 评估ICI再挑战后的疾病控制率 (DCR) 和无进展生存率 (PFS) 等结果.
- 探索对初始免疫疗法的初级和二级耐药性患者之间的结果差异.
主要方法:
- 对45名晚期ESCC患者进行了回顾性队列研究,他们接受了两种基于ICI的疗法.
- 最初的治疗包括ICI与化疗相结合;再挑战治疗使用ICI与血管新生抑制剂.
- 主要结局包括DCR和PFS;记录了与治疗相关的不良事件. 根据6个月的疾病控制持续时间对患者进行了分类.
主要成果:
- 最初的ICI治疗 (ICI-1) 的PFS中位数为6.7个月,DCR为88.9%.
- ICI重试 (ICI-2) 的结果是PFS的中位数为3.2个月,DCR为73.3%.
- 与初级抗性 (11.1%) 相比,ICI-1二次抗性患者在ICI重试后的6个月PFS率 (29.6%) 较高. 与治疗相关的不良事件是可以管理的.
结论:
- 在初始免疫疗法后进展的ESCC患者中,ICI重新挑战可能会提供生存益处和有利的安全概况.
- 获得对初始免疫疗法的耐药性患者可以通过再挑战疗法实现长期的疾病控制.
- 需要进一步的前性研究来优化组合疗法,并确定ICI再挑战的患者群体.

Tumor Immunotherapy
514
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Barrett Esophagus-II: Clinical Manifestations and Management

Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure...
