概括
这项案例研究表明,使用顺序免疫检查点抑制剂成功治疗共存的肝癌和食道癌. 即使在编程死亡连接体1 (PD-L1) 阴性癌症中也实现了持久缓解,这表明免疫协同作用.
科学领域:
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
背景情况:
- 肝细胞癌 (HCC) 和食道状细胞癌 (ESCC) 是一种侵袭性癌症.
- 它们的共存带来了重大的治疗挑战.
研究的目的:
- 报告一种罕见的多焦点HCC和ESCC病例,该病例使用顺序免疫检查点抑制剂 (ICI) 治疗.
- 探索ICI在治疗多种原发性恶性瘤的疗效,包括PD-L1阴性病例.
主要方法:
- 连续给予阿特佐利祖马布加贝瓦齐祖马布,其次是杜尔瓦卢马布加特梅利卢马布.
- 一个患有同时存在的HCC和ESCC的患者的管理.
主要成果:
- 与阿特佐利祖马布和贝瓦齐祖马布观察到的初始瘤回归.
- 尽管有编程死亡连接物1 (PD-L1) 阴性,但在杜尔瓦卢马布和特梅利卢马布治疗中实现了持久缓解.
- 成功治疗多焦点HCC和ESCC.
结论:
- 免疫检查点抑制剂显示出治疗多种原发性恶性瘤的潜力.
- 需要进一步研究预测生物标志物和最佳ICI组合策略.
- 同时存在的瘤之间的免疫协同作用可能会增强PD-L1-阴性癌症的抗瘤反应.

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.

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
