概括
卡博赞提尼布在非小细胞肺癌中对ROS1 L2086F突变显示出有效性,在洛拉提尼布耐药后提供了一种新的治疗选择. 这一发现强调了对耐火性ROS1阳性肺癌的基因组分析的重要性.
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:
- ROS1重组定义了一个非小细胞肺癌 (NSCLC) 的分子亚型,可以通过向疗法治疗.
- 获得后代抑制剂的耐药性,如洛拉提尼布,以及特定突变,如ROS1 L2086F,具有显著的临床挑战,选择有限.
- 本案例报告研究了卡博桑提尼布作为NSCLC的救援疗法,由于ROS1 L2086F突变导致的洛拉提尼布耐药性.
研究的目的:
- 为了评估卡博赞提尼布作为救援疗法的疗效,在患有非小细胞肺癌 (NSCLC) 的患者中,该患者对洛拉提尼布产生了耐药性.
- 在特定的ROS1 L2086F抗性突变的背景下评估卡博桑提尼布的临床益处.
主要方法:
- 一名63岁的女性患有第四阶段肺腺癌和CD74-ROS1融合突变,接受了连续的向治疗.
- 治疗包括一线crizotinib,二线lorlatinib和第三线cabozantinib在lorlatinib进展后.
- 下一代测序确定了获得的ROS1 L2086F耐药性突变,以及并发的mTOR突变和FGFR3基因放大.
主要成果:
- 患者获得了47个月的crizotinib (PFS1) 和11个月的lorlatinib (PFS2) 的无进展生存期 (PFS).
- 在L2086F突变出现后,第三线卡博桑提尼布提供了12个月的PFS (PFS3),疾病稳定和缓解症状.
- 从最初的诊断到总体生存期达到了73个月.
结论:
- 卡博赞提尼布在克服由ROS1 L2086F突变驱动的洛拉提尼布耐药性的临床疗效,提供持久的好处.
- 这一案例凸显了重复进行全面的基因组分析对于管理耐火ROS1阳性NSCLC的重要性.
- 卡博赞提尼布代表了NSCLC耐洛拉提尼布患者的可行的治疗选择,这是由于ROS1 L2086F突变而导致的.

Treatment Resistant Cancers
3.4K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Targeted Cancer Therapies

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.
