概括
免疫检查点抑制剂 (ICI) 对肺部神经内分泌瘤 (NETs),特别是非典型的癌类瘤 (ACs) 是有前途的. 组合疗法,如temozolomide加nivolumab,显示出比单一疗法更高的响应率.
科学领域:
- 在瘤学瘤学.
- 肺部病理学 肺部病理学
- 免疫治疗是一种免疫疗法.
背景情况:
- 肺部神经内分泌瘤 (NETs),包括典型和非典型的癌 (ACs),代表一种罕见的恶性瘤,治疗选择有限.
- 免疫检查点抑制剂 (ICI) 正在成为包括肺 NET 在内的各种癌症的潜在治疗方式.
研究的目的:
- 在患有肺神经内分泌瘤 (NETs) 的患者中系统评估免疫检查点抑制剂 (ICIs) 的疗效.
- 对肺网络中的ICI进行客观反应率 (ORR) 的元分析,包括按干预类型进行子组分析.
主要方法:
- 一个系统的审查和观测和干预研究的元分析报告ICI在肺 NET 的疗效.
- 搜索了Medline,Embase,Web of Science和Cochrane图书馆,截至2024年5月,其中包括11项研究,涉及128名成年患者.
- 排除了案例报告和数据不足的研究;评估了研究质量,并描述性地总结了结果.
主要成果:
- 用ICI治疗的肺NET的整体客观反应率 (ORR) 为14.7%,而非典型癌类药物 (AC) 的ORR显著更高,为44.4%.
- 与ICI单独治疗相比,组合疗法显示出更高ORR的趋势 (p=0.056).
- 泰莫索洛米德加尼沃卢马布的组合实现了最高的ORR,为66.7%. 安全概况与已知的ICI数据一致.
结论:
- 免疫检查点抑制剂 (ICI) 代表了肺神经内分泌瘤 (NETs) 患者,特别是ACs患者的有前途的治疗策略.
- 组合ICI疗法似乎比单一疗法更有效,因此需要在集中的临床试验中进一步调查.
- 需要进一步的研究来优化肺 NET 的 ICI 治疗,并改善患者的治疗结果.

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists
260
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...

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.
