概括

冷物理等离子体与甲基和等化疗药物相结合,增强了Ewing肉瘤中的癌细胞死亡. 这种新的方法有望改善这种罕见的骨癌患者的治疗结果.

科学领域:

在瘤学瘤学.
生物物理学的生物物理.
癌症研究癌症研究

背景情况:

尤文肉瘤 (ES) 是一种高度恶性骨瘤,影响儿童和青少年.
目前的化疗改善了生存率,但转移性ES生存率仍然很低 (~30%).
化疗往往会引起显著的副作用,影响患者的生活质量.

研究的目的:

为了研究冷物理血 (CPP) 与非标准化疗剂相结合的协同效应,用于尤宁肉瘤.
评估CPP和化疗组合对ES细胞增殖,活力和亡的影响.

主要方法:

两个ES细胞系 (RD-ES和A673) 用IC20度的西斯普拉丁和甲酸盐 (MTX) 进行治疗.
组合疗法包括在冷物理等离子体 (CPP) 旁边用化疗剂治疗细胞.
对人口翻倍,细胞活力和亡过程的评估影响.

主要成果:

组合疗法显著降低了ES细胞系的种群翻倍和细胞活力.
与CPP单独治疗相比,在CPP和化疗治疗的细胞中观察到亡活性的增加.
对于CPP与MTX和cisplatin相结合,已经证明了协同作用的抗癌作用.

结论:

将冷物理等离子体与非标准化疗药物 (甲基,思) 结合起来,可以增强抗ES效应.
这种组合疗法提供了一种有希望的策略,以提高尤宁肉瘤的治疗疗效.
研究结果表明,治疗这种具有挑战性的骨癌的新疗法可能存在.

Combination Therapies and Personalized Medicine

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
