概括
将阿维卢马布添加到 cetuximab rechallenge 并没有改善转移性结直肠癌 (mCRC) 的结果. 液体活检的综合基因组分析 (CGP) 确定了受益于抗EGFR治疗的患者.
科学领域:
- 在瘤学瘤学.
- 基因组学就是基因组学.
- 临床试验 临床试验
背景情况:
- 抵抗性转移性结肠直肠癌 (mCRC) 可能受益于抗皮肤生长因子受体 (EGFR) 药物重新挑战.
- 识别预测生物标志物对于优化mCRC的治疗策略至关重要.
研究的目的:
- 为了评估 cetuximab 的疗效,与或没有 avelumab,在患有 RAS/BRAF 野生型 (WT) mCRC.
- 评估基线血ctDNA综合基因组分析 (CGP) 在选择患者接受抗EGFR治疗中的作用.
主要方法:
- 随机的第2期CAVE-2GOIM试验比较了RAS/BRAF WT mCRC中的单一治疗与 cetuximab加上 avelumab.
- 患者的选择是基于使用FoundationOne Liquid CDx.的血ctDNA CGP.
- 主要终点是整体生存 (OS);无进展生存 (PFS) 和目标反应率 (ORR) 也被分析.
主要成果:
- 在组合和单一治疗手臂之间没有观察到中位数PFS (5.3 vs 4.3 个月) 或中位数OS (14.8 vs 12.9 个月) 的显著差异.
- 探索性分析显示,患有"负超选择" (关键EGFR通路基因没有基因组变化) 的患者在两只手臂都显著改善了mPFS和mOS.
- "消极超选择"组表现出优异的结果,突出显示了基因组分析对治疗选择的重要性.
结论:
- 在mCRC中添加avelumab与cetuximab重新挑战并没有提高疗效.
- 液体活检CGP是识别受益于抗EGFR复试的患者的宝贵工具,支持其融入mCRC护理.
- 这项研究 (临床试验编号:NCT05291156) 强调了基因组生物标志物在指导治疗决策中的重要性.

Treatment Resistant Cancers
3.7K
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.
