概括
强度调节辐射疗法 (IMRT) 再辐射与尼沃卢马布相结合显示,改善了头部和部状细胞癌 (HNSCC) 的无进展生存期 (PFS). 这种组合疗法耐受性良好,需要对HNSCC患者进行进一步的研究.
科学领域:
- 在瘤学瘤学.
- 辐射瘤学 辐射瘤学
- 免疫治疗是一种免疫疗法.
背景情况:
- 强度调节辐射疗法 (IMRT) 对复发性或第二次主发性头角状细胞癌 (HNSCC) 的再辐射与不良的无进展生存率 (PFS) 和整体生存率 (OS) 相关.
- 尼沃卢马布是HNSCC的批准治疗标准,但其与IMRT再辐射相结合的作用需要进一步调查.
研究的目的:
- 为了评估耐受性,PFS,OS,以及患者报告的尼沃卢马布在IMRT再照射期间和之后在患有复发性或第二次原发性HNSCC.患者的患者中所给予的结果.
- 评估这种联合治疗方法的安全性和有效性.
主要方法:
- 一个多中心的,非随机的,第二阶段,单臂试验,涉及符合特定标准的复发性或第二次原发性HNSCC患者 (递归分区分析类别1和2).
- 患者接受IMRT (60-66 Gy) 与尼沃卢马布 (240毫克每2周,从IMRT前2周开始) 同时接受,随后接受辅助尼沃卢马布 (480毫克每4周,共52周).
- 主要终点是PFS;次要终点包括OS,毒性,患者报告的结果和生物标志物相关性.
主要成果:
- 估计的一年PFS为61.7%,明显优于历史对照率<43.8% (P=.002).
- 最常见的3级或更高的不良事件是淋巴缺血 (4%);其他3级+事件发生在≤2%的患者中.
- 生活质量得分保持稳定,假设生成趋势表明PFS/OS与特定血液T细胞标记物之间的潜在关联.
结论:
- 与尼沃卢马布相结合的IMRT再辐射表明,与历史对照相比,对于复发性或第二次初级HNSCC的PFS有望改善.
- 治疗方案耐受性良好,毒性可控,生活质量稳定.
- 这种组合疗法需要进一步调查,并支持在临床试验中继续评估.

Tumor Immunotherapy
515
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
159
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...
