原发性脑肿瘤是起源于中枢神经系统细胞的一组异质性恶性肿瘤。已经开发了各种易于临床前研究的模型来概括人类脑肿瘤,使我们能够了解潜在的病理生物学并探索潜在的治疗方法。然而,使用临床前模型确定的许多有前途的治疗策略在临床试验阶段显示出有限的疗效或失败。无法开发出显著提高患者生存率的治疗策略,这突出表明迫切需要重新审视目前可用的动物模型的设计,并探索新模型的使用,使我们能够弥合有希望的临床前发现和临床转化之间的差距。在这篇综述中,我们将讨论目前用于模拟胶质母细胞瘤的策略,这是成人中最恶性的脑肿瘤,并强调必须规避特定模型的缺点,以开发创新的治疗策略。
Primary brain tumors are a heterogeneous group of malignancies that originate in cells of the central nervous system. A variety of models tractable for preclinical studies have been developed to recapitulate human brain tumors, allowing us to understand the underlying pathobiology and explore potential treatments. However, many promising therapeutic strategies identified using preclinical models have shown limited efficacy or failed at the clinical trial stage. The inability to develop therapeutic strategies that significantly improve survival rates in patients highlight the compelling need to revisit the design of currently available animal models and explore the use of new models that allow us to bridge the gap between promising preclinical findings and clinical translation. In this review, we will discuss current strategies used to model glioblastoma, the most malignant brain tumor in adults and highlight the shortcomings of specific models that must be circumvented for the development of innovative therapeutic strategies.
