概括
在分子瘤板 (MTBs) 中集成超出下一代测序 (NGS) 的额外生物标志物显著扩大了高级癌症向治疗的资格. 这种方法提高了临床效益率,并提高了精确的瘤学结果.
科学领域:
- 在瘤学瘤学.
- 基因组学就是基因组学.
- 生物标志物发现发现
背景情况:
- 分子瘤板 (MTB) 对于指导罕见和晚期癌症的治疗选择至关重要.
- 下一代测序 (NGS) 是一种标准的诊断工具,但结合额外的生物标志物可能会发现更多可操作的发现.
- 新兴的生物标志物,如人体表皮生长因子受体2 (HER2) 低,同源重组缺陷 (HRD) 和抗体药物合物 (ADC) 的标,在各种瘤类型中显示出有前途.
研究的目的:
- 调查将标准NGS之外的补充生物标记分析集成到分子瘤委员会中的治疗建议和临床结果上的影响.
- 评估诸如HER2低状态,HRD和ADC目标等生物标志物的实用性,以扩大晚期癌症患者的治疗选择.
- 以全面的生物标志物评估为指导,评估接受治疗的患者的临床益处率.
主要方法:
- 瘤样本使用TSO500®瘤突变负担 (TMB) 面板进行分析.
- 通过免疫组织化学 (IHC) 和光在位杂交 (FISH) 来确定HER2状态.
- 额外的评估包括ADC IHC,微卫星不稳定性 (MSI) PCR,不匹配修复 (MMR) IHC,编程死亡配体1 (PD-L1) IHC和HRD分析. 进行了每周MTB讨论和结果跟踪.
主要成果:
- 在658名患者中,有329人接受了治疗建议,其中182人基于补充生物标志物. 实行了100条建议,其中37%来自这些补充诊断.
- 在64名可评估反应的患者中,临床益处率为45.3%.
- 低HER2状态扩大了向治疗选择,HRD分析完善了PARP抑制剂的分层,ADC IHC支持了20个建议和2个实施方案.
结论:
- 将额外的生物标志物评估集成到MTB工作流程中,可以显著提高精确瘤学.
- 这种综合性方法扩大了有资格接受向治疗的患者群,从而改善了治疗策略.
- 该研究强调了多模式生物标志物分析在最大限度地提高癌症患者治疗机会的价值.

Targeted Cancer Therapies
8.6K
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
5.9K
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...
