概括
奥西默提尼布在患有不常见EGFR突变的非小细胞肺癌 (NSCLC) 患者中显示出有前途的疗效,包括非典型的EXON 19和复合突变. 需要进一步的研究,以优化这些罕见病例的治疗.
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:
- 非小细胞肺癌 (NSCLC) 经常携带表皮生长因子受体 (EGFR) 突变.
- 不常见的EGFR突变,如非典型的外基因19缺失和复合突变,占病例的20%.
- 在患有这些罕见突变的患者中,奥西默蒂尼布的疗效尚未得到充分证实.
研究的目的:
- 评估一线奥西默蒂尼布在患有罕见EGFR外基因19或复合突变的NSCLC患者中的疗效.
- 评估应答率,无进展生存期 (PFS),治疗终止时间 (TTD) 和整体生存期 (OS).
主要方法:
- 对37名接受一线 osimertinib 治疗的 NSCLC 患者的回顾性分析.
- 纳入标准:非典型的EGFR外基因19或复合突变.
- 通过使用响应评估标准在固体瘤 (RECIST) v1.1和卡普兰-梅尔分析来评估结果.
主要成果:
- 总体应答率 (ORR) 为76%,PFS的中位数为13个月.
- 中位数TTD为22个月,中位数OS为36个月.
- 亚组分析显示,非典型的外型19突变的ORR为80%,复合突变的ORR为67%.
结论:
- 奥西默提尼布在患有罕见EGFR外基因19和化合物突变的NSCLC患者中表现出良好的结果.
- 治疗结果各不相同,这凸显了对罕见EGFR变异的进一步研究的需要.
- 个性化管理策略对于优化患者护理至关重要.

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.

Combination Therapies and Personalized Medicine
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...
