概括
与单独化疗相比,新辅助化疗免疫疗法显著改善了可切除非小细胞肺癌 (NSCLC) 患者的结局,显示出较高的病理反应和生存率,而不会增加手术风险.
科学领域:
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
- 手术瘤学手术瘤学
背景情况:
- 新辅助化疗免疫疗法在可切除的非小细胞肺癌 (NSCLC) 中显示出前景.
- 检查Mate-816试验证实了其在改善病理反应和无事件生存 (EFS) 中的有效性.
- 现实世界的数据对于验证这些发现和评估安全至关重要.
研究的目的:
- 评估可切除NSCLC的新辅助化疗免疫疗法的现实安全性和可行性.
- 为了在临床环境中比较新辅助化疗免疫疗法与单独化疗的结果.
- 分析治疗周期对手术结果的影响.
主要方法:
- 对接受手术后新辅助治疗的NSCLC患者的临床数据的回顾性分析.
- 化学免疫疗法和单独化学疗法组之间的比较.
- 基于治疗周期 (1-2 vs. 3-5 周期) 的化疗免疫疗法的子组分析.
- 主要终点:EFS和主要病理反应 (MPR);次要终点:PCR,OS,TRAEs和外科指标.
主要成果:
- 与单独使用化疗相比,新辅助化疗免疫疗法显示出明显更高的MPR (57.4%对14.3%) 和pCR (46.3%对0%) 率.
- 在24个月后,化学免疫疗法的EFS率为77.0%,仅化学疗法为56.7% (P=0.026).
- 在24个月的总生存率分别为87.1%和67.7% (P=0.020).
- 在1-2至3-5个化学免疫治疗周期之间,没有观察到手术时间,血液损失或术后并发症的显著差异.
结论:
- 新辅助化学免疫疗法对可切除的NSCLC比单独的化疗更有效.
- 这种方法不会增加手术风险.
- 化疗免疫治疗周期的数量并没有显著影响手术难度.

Tumor Immunotherapy
529
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.

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists
167
Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy. SP binds and activates...
