Cancer Research | 高通量药物筛选为高危肿瘤患儿提供新的治疗策略
2017年9月至2022年9月期间,ZERO项目对来自166例患者的169个肿瘤样本进行体外高通量药物筛选试验。其中125个样本成功地进行了药物筛选,涵盖了脑肿瘤、血液系统恶性肿瘤、神经母细胞瘤、肉瘤和其他实体肿瘤等多种儿童肿瘤。该项目中用于高通量药物筛选的肿瘤模型通过以下四种方法获得:1)将新鲜肿瘤组织解离成活的单细胞直接进行药物筛选;2)体外扩增解离的肿瘤细胞进行药物筛选;3)将肿瘤组织在小鼠体内扩增进行药物筛选;4)肿瘤组织在小鼠体内扩增后再进行解离并体外扩增后获得的肿瘤细胞进行药物筛选。

原文摘要(Abstract)
For one-third of patients with pediatric cancer enrolled in precision medicine programs, molecular profiling does not result in a therapeutic recommendation. To identify potential strategies for treating these high-risk pediatric patients, we performed in vitro screening of 125 patient-derived samples against a library of 126 anticancer drugs. Tumor cell expansion did not influence drug responses, and 82% of the screens on expanded tumor cells were completed while the patients were still under clinical care. High-throughput drug screening (HTS) confirmed known associations between activating genomic alterations in NTRK, BRAF, and ALK and responses to matching targeted drugs. The in vitro results were further validated in patient-derived xenograft models in vivo and were consistent with clinical responses in treated patients. In addition, effective combinations could be predicted by correlating sensitivity profiles between drugs. Furthermore, molecular integration with HTS identified biomarkers of sensitivity to WEE1 and MEK inhibition. Incorporating HTS into precision medicine programs is a powerful tool to accelerate the improved identification of effective biomarker-driven therapeutic strategies for treating high-risk pediatric cancers.
Significance: Integrating HTS with molecular profiling is a powerful tool for expanding precision medicine to support drug treatment recommendations and broaden the therapeutic options available to high-risk pediatric cancers.
