概括
一个新的共识免疫衍生的基因签名 (CIDGS) 准确地预测了头部和部状细胞癌 (HNSCC) 的结果. 较低的CIDGS得分与更好的预后和提高免疫治疗敏感性相关,为HNSCC患者分层提供了一个有希望的生物标志物.
科学领域:
- 在瘤学瘤学.
- 基因组学就是基因组学.
- 生物信息学是一种生物信息学.
背景情况:
- 头角状细胞癌 (HNSCC) 是一种具有不良患者结局的侵袭性恶性瘤.
- 目前的分期系统缺乏有效选择治疗所需的精度.
- 迫切需要一个可靠的生物标志物来早期检测HNSCC和量身定制的治疗.
研究的目的:
- 开发和验证一种用于预测HNSCC预后的新型基因特征.
- 确定一个生物标志物,可以指导治疗决策,并改善患者分层.
- 探索基因特征,基因组变化,免疫细胞透和治疗反应之间的关系.
主要方法:
- 利用十种不同的机器学习算法和85种组合来构建共识免疫衍生基因签名 (CIDGS).
- 应用CIDGS来分析三个独立队列 (719名HNSCC患者) 的基因表达特征.
- 验证了CIDGS的预测性能与现有的签名和临床特征相比.
主要成果:
- 开发的CIDGS准确地预测了对HNSCC的培训,测试和元队列的预后.
- 当与临床数据相结合时,CIDGS与其他签名相比显示出更高的预测能力.
- 患有低CIDGS的患者表现出更少的基因组变化,更高的免疫透率和更好的免疫治疗反应,以及改善的预后.
- 高CIDGS得分与HNSCC患者的生存时间缩短有关.
- CIDGS还在分层免疫治疗反应和膀癌的预后方面表现出有效性.
- 尼克洛萨米德和鲁克索利提尼布成为高CIDGS的HNSCC患者的潜在治疗药物.
结论:

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.
