为了改善去势抵抗性前列腺癌(CRPC)患者未来的药物开发和患者管理,迫切需要与相关结果相关的替代生物标志物。生物标志物必须是可测量的,可重复的,与相关临床结果相关联的,并证明实用性。这是一个快速发展的领域,最近的CRPC试验结合了循环肿瘤细胞(ctc)的检测、成像和患者报告的结果生物标志物。我们讨论了CRPC生物标志物的开发框架,包括不同的类别和使用背景。我们还强调了分析验证的要求,临床验证和监管批准所需的试验顺序,以及成像和CTC生物标志物的未来前景。
To improve future drug development and patient management for patients with castration-resistant prostate cancer (CRPC), surrogate biomarkers that are linked to relevant outcomes are urgently needed. A biomarker must be measurable, reproducible, linked to relevant clinical outcomes, and demonstrate utility. This is a rapidly evolving area, with recent trials in CRPC incorporating the detection of circulating tumour cells (CTCs), imaging, and patient-reported outcome biomarkers. We discuss the framework for the development of biomarkers for CRPC, including different categories and contexts of use. We also highlight the requirements of analytical validation, the sequence of trials needed for clinical validation and regulatory approval, and the future outlook for imaging and CTC biomarkers.
