概括
ALKTERNATE研究发现,交替的洛拉提尼布和克里佐替尼布是ALK阳性肺癌的可行治疗方法,有望通过ctDNA监测来控制耐药性和改善结果.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 药理学 药理学是指药理学的学科.
背景情况:
- 阳性ALK肺癌在分子层面上是多样化的,并且由于药物耐药性而容易复发.
- 循环瘤DNA (ctDNA) 的动态监测提供了对治疗选择压力和抵抗通路的洞察力.
研究的目的:
- 研究ALK阳性非小细胞肺癌 (NSCLC) 对第二代ALK抑制剂耐药的患者固定的洛拉提尼布和克里佐提尼布交替循环的可行性,安全性和疗效.
- 探索动态ctDNA资料,治疗反应和疾病复发之间的相关性.
主要方法:
- 该ALKTERNATE研究是一个单臂的试点研究.
- 参与者接受了洛拉提尼布和克里佐替尼布的交替循环.
- 使用ctDNA来监测疾病反应,耐药性,并与生存结果相关联.
主要成果:
- 替代疗法在12名参与者中证明了安全性,可行性和有效性.
- 治疗失败的中位时间为10个月,整体存活期为23个月.
- 在具有先前存在TP53突变或在基线未清除ctDNA的患者中,ctDNA档案确定了较低的存活率.
结论:
- 交替ALK抑制剂策略对于ALK阳性NSCLC是可行的.
- 实时等离子体分析可以为灵活的治疗设计提供信息.

4.9K
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...

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
