概括
双重免疫检查点抑制剂 (ICI) 对不可切除的肝细胞癌 (HCC) 提供了比传统的抗血管性疗法更持久的反应和更高的长期存活率. 结合有限的VEGF抑制与ICI的精细策略可以优化肝癌患者的疗效和安全性.
科学领域:
- 肝细胞癌 (HCC) 治疗方法
- 癌症免疫疗法癌症免疫疗法
- 血管内皮生长因子 (VEGF) 抑制抑制
背景情况:
- 肝细胞癌 (HCC) 的治疗选择,特别是肝硬化不能切除的病例,历史上是有限的.
- 使用血管内皮生长因子 (VEGF) 抑制剂的初始全身疗法提供了适度的生存益处,但缺乏持久的反应.
- 长期的VEGF封锁引起了人们对肝/毒性和肝癌的长期有效性有限的担忧.
研究的目的:
- 评估从以VEGF为中心的疗法转向免疫检查点抑制剂 (ICI) 的范式转变.
- 与抗VEGF药物相比,评估双ICI疗法对反应耐久性和长期生存的影响.
- 提出精细的治疗策略,优化晚期肝癌的疗效和安全性.
主要方法:
- 对临床试验数据的审查,比较抗VEGF疗法与免疫检查点抑制剂 (ICI) 对不可切除的HCC.
- 分析不同治疗方式的响应持续时间,整体存活率和毒性概况.
- 评估将VEGF抑制与ICI结合的潜在好处和缺点.
主要成果:
- 与之前的VEGF抑制剂相比,双重ICI疗法在HCC中显示出更持久的反应和更高的长期存活率.
- 抗VEGF疗法虽然对最初的瘤减少有用,但可能会对肝脏再生产生负面影响,并且在长时间使用时恶化门高血压.
- 双重ICI的有效性挑战了传统的以VEGF为中心的方法,表明了更具变革性的疾病控制的潜力.
结论:
- 双免疫检查点抑制剂 (ICI) 是一个重大进步,为不可切除的肝细胞癌提供了改善的长期结果.
- 一个精细的策略,包括有限时间的VEGF抑制,其次是ICI或与ICI结合,可以提高疗效和安全性.
- 未来的研究应优先确定ICI反应的预测生物标志物,并开发新的疗法,以最大限度地提高晚期肝癌的生存率.

Targeted Cancer Therapies
7.8K
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.

Treatment Resistant Cancers
3.4K
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...
