PNAS:致命脑肿瘤的新希望!三氟拉嗪与放射线结合

2020-05-04 Allan MedSci原创

加州大学洛杉矶分校约翰逊综合癌症中心的研究人员发现,将一种曾经用于治疗精神分裂症的药物(三氟拉嗪)添加到传统放疗中有助于改善胶质母细胞瘤小鼠的整体生存。胶质母细胞瘤是最致命,最难治疗的脑肿瘤之一。

加州大学洛杉矶分校约翰逊综合癌症中心的研究人员发现,将一种曾经用于治疗精神分裂症的药物(三氟拉嗪)添加到传统放疗中有助于改善胶质母细胞瘤小鼠的整体生存。胶质母细胞瘤是最致命,最难治疗的脑肿瘤之一。这项发现发表于《美国国家科学院院刊,PNAS》。更重要的是,放射线和三氟拉嗪的结合不仅针对胶质细胞瘤细胞,而且还有助于克服这种侵袭性癌症常见的耐药性。

放射线是癌症患者治疗不可或缺的一部分,也是最有效的治疗方法之一。在许多情况下,它可以帮助治愈疾病。但是在胶质母细胞瘤中,肿瘤细胞通常会变得对放射线有抵抗力,因为放射线本身可以诱导“表型转化”,这一过程将某些非肿瘤干细胞转变为产生肿瘤的细胞,从而导致癌症复发。

加州大学洛杉矶分校Frank Pajonk博士说:“虽然放疗是能延长胶质母细胞瘤患者生存的少数疗法之一,但由于高度侵袭性,单独的放疗在我们的模型中对疾病的治疗作用很小。药物三氟拉嗪本身不起作用,但是三氟拉嗪与放射线结合使用时,它们将变得非常高效”。
