概括
乙型肝炎病毒 (HBV) 的DNA水平会影响晚期肝细胞癌 (HCC) 患者在抗PD-1免疫治疗期间的预后,无论病毒载量如何. 无法检测到的HBVDNA与更好的短期生存相关,这表明它不应该将患者排除在治疗之外.
科学领域:
- 在瘤学瘤学.
- 肝病学 肝病学是一种肝病学.
- 病毒学 病毒学
背景情况:
- 在接受免疫治疗的晚期肝细胞癌 (HCC) 患者中,乙型肝炎病毒 (HBV) 负荷的预后意义尚不清楚.
- 研究HBVDNA水平,免疫疗法疗效和患者结果之间的相互作用对于优化治疗策略至关重要.
研究的目的:
- 确定在接受抗PD-1免疫治疗的晚期HCC患者中,HBV DNA水平与生存结果 (无进展生存[PFS]和整体生存[OS]) 之间的相关性.
- 评估HBV DNA负载对免疫治疗期间不良事件,特别是肝功能障碍的发生率的影响.
主要方法:
- 一项多中心研究包括162名先进的HCC患者,从2019年12月到2023年接受了抗PD-1免疫疗法和恩特卡维尔治疗.
- 患者根据基线HBVDNA水平分层 (≤2000 IU/ml与>2000 IU/ml,以及不可检测与可检测).
- 无进展生存率 (PFS),总生存率 (OS) 和不良事件与HBV DNA状态相关评估.
主要成果:
- 在HBVDNA水平≤2000 IU/ml与>2000 IU/ml的患者之间没有观察到PFS或OS中位数的显著差异 (PFS:4.60与3.90个月,p=0.17;OS:10.53与8.17个月,p=0.14).
- 基线未检测HBVDNA的患者比检测水平的患者显著表现出更好的PFS (5.03比3.70个月,p=0.03),尽管OS没有显著差异 (11.80比8.00个月,p=0.10).
- 肝功能障碍的发生率与基线HBVDNA负载没有显著的相关性 (6.1%与7.9%,p>0.05).
结论:
- 在免疫疗法期间,HBV DNA 状态会影响HCC 患者的预后,独立于特定的病毒载量.
- 无法检测到的HBVDNA与接受免疫治疗的晚期HCC患者更有利的短期生存结果有关.
- 升高的HBVDNA水平不应阻止接受有效抗病毒治疗的患者获得免疫疗法的资格.

Tumor Immunotherapy
667
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.

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
