概括
预后营养指数 (PNI) 预测了接受免疫治疗的高级头癌患者的结果. 这种营养标志物,与炎症标志物不同,显示出无进展和整体存活的显著预测价值.
科学领域:
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
- 生物标志物发现发现
背景情况:
- 免疫检查点抑制剂 (ICI) 是高级头部和部状细胞癌 (HNSCC) 的标准.
- 编程死亡配体1 (PD-L1) 用于ICI选择,但缺乏治疗反应的预测生物标志物.
- 这项研究调查了炎症和营养参数,以预测HNSCC中的ICI结果.
研究的目的:
- 为了评估炎症和营养指数对治疗结果的预测价值,先进的HNSCC患者接受PD-1阻塞治疗.
- 确定可靠的生物标志物,以预测HNSCC.免疫治疗的反应.
主要方法:
- 分析了接受PD-1阻塞的65名晚期HNSCC患者.
- 评估了炎症标志物 (中性细胞与淋巴细胞比率 (NLR),血小板与淋巴细胞比率 (PLR),全身免疫炎症指数 (SII)) 和预后营养指数 (PNI).
- 检查了与患者结果的相关性,包括客观反应率,疾病控制率,无进展生存期 (PFS) 和整体生存期 (OS).
主要成果:
- 年龄和表现状况影响了炎症和营养标志物.
- 虽然观察到客观反应和疾病控制率,但NLR,PLR,SII和PNI在响应者和非响应者之间没有显著差异.
- 单变量分析表明NLR,PLR,SII和PNI预测了PFS和OS.
- 多变量分析确定PNI是PFS和OS的独立预测因素.
结论:
- 预后营养指数 (PNI) 是治疗PD-1封锁的高级HNSCC患者结果的重要预测指标.
- 与NLR,PLR和SII等炎症标志物相比,PNI对治疗结果的预测价值更高.
- 由PNI评估的营养状况在预测HNSCC的免疫治疗反应方面发挥着至关重要的作用.

Tumor Immunotherapy
493
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.
