概括
在不可切除的肝细胞癌 (uHCC) 中预测对组合免疫疗法的反应至关重要. 鉴定了对布罗利祖马布加伦瓦提尼布 (PL) 治疗有反应或有进展的患者的独特免疫细胞概况 (ICPs),有助于治疗选择.
科学领域:
- 免疫学 免疫学 免疫学
- 在瘤学瘤学.
- 机器学习 机器学习
背景情况:
- 不切除的肝细胞癌 (uHCC) 治疗通常涉及组合免疫疗法,如pembrolizumab加lenvatinib (PL).
- 预测患者对HPCC的PL治疗的反应仍然是一个重大的临床挑战.
- 确定治疗疗效的生物标志物对于优化患者治疗结果至关重要.
研究的目的:
- 为了比较响应 (R) 和不响应 (NR) 于PL治疗的hHCC患者之间的免疫细胞概况 (ICP).
- 确定特定的免疫细胞亚群,区分响应者和非响应者.
- 开发一种机器学习模型,以基于基线ICP来预测治疗反应.
主要方法:
- 预期招募51名接受PL治疗的HHCC患者.
- 在开始治疗之前收集和分析周围血液免疫细胞概况.
- 使用基线ICP数据开发机器学习模型,以分类响应者和非响应者.
主要成果:

Combination Therapies and Personalized Medicine
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Tumor Immunotherapy
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.
