肿瘤免疫治疗的新辅助检查点阻断
作者:小柯机器人 发布时间:2020/2/10 11:38:05

美国约翰霍普金斯大学Suzanne L. Topalian等研究人员总结了肿瘤免疫治疗中的新辅助检查点阻断研究。2020年1月31日,国际知名学术期刊《科学》发表了这一论文。

研究人员表示,靶向程序性细胞死亡1(PD-1):程序性死亡配体1(PD-L1)免疫检查点途径的癌症免疫疗法已开启了肿瘤学的新时代。阻断PD-1或PD-L1的药物可促进内源性抗肿瘤免疫力,并且由于其广泛的活性谱,已被视为癌症治疗的共同方向。然而,许多晚期肿瘤表现出从头开始或获得了治疗抗性,并且目前的研究工作集中在改善患者预后上。在早期癌症中使用抗PD-1或抗PD-L1治疗被认为是一种有效解决方案。
 
研究人员综述了PD-1途径阻断时代新辅助(术前)免疫疗法的发展,重点介绍了生物学机制、临床试验设计和病理反应评估。新辅助免疫疗法研究的发现可能会揭示在新组合疗法中共同靶向的途径、机制和分子,从而提高抗PD-1和抗PD-L1的功效。

Title: Neoadjuvant checkpoint blockade for cancer immunotherapy

Abstract: Cancer immunotherapies that target the programmed cell death 1 (PD-1):programmed death-ligand 1 (PD-L1) immune checkpoint pathway have ushered in the modern oncology era. Drugs that block PD-1 or PD-L1 facilitate endogenous antitumor immunity and, because of their broad activity spectrum, have been regarded as a common denominator for cancer therapy. Nevertheless, many advanced tumors demonstrate de novo or acquired treatment resistance, and ongoing research efforts are focused on improving patient outcomes. Using anti–PD-1 or anti–PD-L1 treatment against earlier stages of cancer is hypothesized to be one such solution. This Review focuses on the development of neoadjuvant (presurgical) immunotherapy in the era of PD-1 pathway blockade, highlighting particular considerations for biological mechanisms, clinical trial design, and pathologic response assessments. Findings from neoadjuvant immunotherapy studies may reveal pathways, mechanisms, and molecules that can be cotargeted in new treatment combinations to increase anti–PD-1 and anti–PD-L1 efficacy.
