概括
与nab-paclitaxel和gemcitabine (AG) 相比,nab-paclitaxel加S-1 (AS) 在晚期胰腺癌患者中显著改善了无进展生存率和整体生存率. 该AS疗法表现出优越的疗效,具有相似的安全性.
科学领域:
- 在瘤学瘤学.
- 临床药理学 临床药理学
- 胃肠病学 胃肠病学
背景情况:
- 在之前的小规模研究中,Nab-paclitaxel加S-1 (AS) 已经显示出有前途的抗瘤活性.
- 晚期胰腺癌 (PC) 仍然是一个重大的临床挑战,需要有效的第一线治疗.
- 标准的治疗方法nab-paclitaxel加上gemcitabine (AG) 是高级PC的常见一线选择.
研究的目的:
- 为了比较AS治疗方案与AG治疗方案的疗效和安全性,作为晚期胰腺癌的第一线治疗.
- 评估无进展生存期 (PFS) 作为主要终点.
- 评估整体生存率 (OS) 和客观反应率.
主要方法:
- 一个多中心的,随机的,二期试验,涉及无法切除,局部发达或转移性PC的患者.
- 患者被随机分配1:1接受AS或AG6个周期.
- 纳布-帕克利塔塞尔 (125 mg/m2) 在第1天和第8天被施用. 在1至14天,S-1每天服用两次,在1日和8日服用凝胺 (1000毫克/米2).
主要成果:
- 与AG组相比,AS组的PFS中位数显著更长 (8.48与4.47个月;HR=0.402) 和OS (13.73与9.59个月;HR=0.226).
- 在AS组 (37.50%) 的客观反应率高于AG组 (6.67%).
- 在这两组中,常见的3-4级不良事件包括中性质衰竭和白血病衰竭;高马谷氨基转移酶仅在AG组中被观察到.
结论:
- 与AG疗法相比,一线AS疗法在中国患者中显著改善了晚期PC的PFS和OS.
- 该AS方案提供了与AG方案相比较的安全概况.
- 这项研究支持AS作为晚期胰腺癌的潜在新标准一线治疗.

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists
158
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...
