概括
将高剂量外部光束放射治疗添加到阿特佐利祖马布加贝瓦齐祖马布,显著改善了晚期肝细胞癌 (HCC) 患者的治疗结果,显示出更好的反应率和整体存活率,而不会增加不良事件.
科学领域:
- 肝胆瘤学 肝胆瘤学
- 辐射瘤学 辐射瘤学
- 医学瘤学 医学瘤学
背景情况:
- 阿特佐利祖马布加贝瓦齐祖马布是推治疗晚期肝细胞癌 (HCC) 的治疗方法.
- 高剂量的外部光束放射治疗 (RT) 提供了优秀的局部瘤控制.
- 在高度发达的HCC中,阿特佐利祖马布,贝瓦齐祖马布和RT的组合仍未得到充分探索.
研究的目的:
- 评估同步治疗阿特佐利祖马布加贝瓦齐祖马布和高剂量RT的疗效和安全性,用于高度发达HCC的患者.
- 为了比较同时接受阿特佐利祖马布-贝瓦西祖马布和RT与单独接受阿特佐利祖马布-贝瓦西祖马布的患者之间的结果.
主要方法:
- 一项回顾性研究比较了13名患有高度晚期HCC的患者 (Vp4门静脉血栓塞或>50%的肝体积瘤),同时接受阿特佐利祖马布-贝瓦西祖马布和RT (A组) 和34名仅接受阿特佐利祖马布-贝瓦西祖马布 (B组) 的患者.
- 组A接受了质子 (72.6 GyE/22 分数) 或光子 (54 Gy/18 分数) RT.
- 主要终点包括客观反应率 (ORR) 和整体存活率 (OS).
主要成果:
- 与B组相比,A组表现出明显更高的ORR (50.0%对11.8%,P<.01) 和更长的OS (未达到对5.5个月,P=.01) 与B组相比.
- 同时的RT是较长寿命的独立预测因子 (HR:0.18;95% CI,0.05-0.63,P<.01).
- 不良事件发生率 (任何等级和等级≥3) 在两组之间是相似的.
结论:
- 同时使用高剂量的外部光束放射治疗可以安全地提高阿特佐利祖马布加贝瓦西祖马布在高度发达的HCC中的疗效.
- 这些初步发现表明,对于这种患者群体来说,这是一个有前途的治疗策略.
- 需要进一步的前性研究来验证这些结果.

Targeted Cancer Therapies
7.6K
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.

Tumor Immunotherapy
523
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.
