概括
第一线皮罗替尼组合疗法对HER2突变非小细胞肺癌 (NSCLC) 显著的生存益处. 这种治疗提供了一个可行的选择,具有可控的毒性,尽管脑转移表明预后较差.
科学领域:
- 在瘤学瘤学.
- 遗传学 是一个遗传学.
- 药理学 药理学是指药理学的学科.
背景情况:
- HER2突变是高级非小细胞肺癌 (NSCLC) 的罕见驱动因素,治疗选择有限.
- 鉴定HER2突变NSCLC的特征对于开发有效的治疗策略至关重要.
研究的目的:
- 为了研究HER2突变NSCLC的分子格局.
- 评估基于pyrotinib的组合疗法的临床疗效和安全性,作为对HER2突变NSCLC的第一线治疗.
主要方法:
- 下一代测序 (NGS) 用于144个HER2突变NSCLC病例的分子概况.
- 使用RECIST 1.1和生存分析 (Kaplan-Meier,日志等级测试) 评估治疗反应.
- 基于pyrotinib的组合疗法的治疗疗效和毒性的评估.
主要成果:
- 最常见的HER2突变是exon 20p.A775_G776insYVMA (47.9%);TP53是经常发生的共同突变 (10.4%).
- 皮洛替尼组合治疗实现了33.3%的客观应答率 (ORR),95.2%的疾病控制率 (DCR),11.3个月的中位数无进展生存期 (mPFS) 和21.0个月的中位数整体生存期 (mOS).
- 大脑转移显著恶化预后 (mPFS: 5.1 个月,mOS: 9.3 个月). 腹是最常见的与治疗相关的不良事件 (TRAE).
结论:
- 基于pyrotinib的组合疗法是一种可行的和有效的第一线治疗HER2突变NSCLC,提供显著的生存优势.
- 治疗表明可控毒性,腹是最常见的不良事件.
- 脑转移的患者需要加强管理策略,因为结果较差.

Combination Therapies and Personalized Medicine
4.8K
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...

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.
