概括
针对晚期胆管癌 (CCA) 的扩展分子分析 (EMP) 正在增加,但对向治疗的获取仍然有限. 向治疗显著提高了CCA患者的整体存活率 (OS),突出了改善治疗机会的必要性.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 癌症研究 癌症研究
背景情况:
- 扩展分子分析 (EMP) 对于高级胆管癌 (CCA) 的向治疗选择至关重要.
- 关于EMP影响和CCA中向治疗可用性的现实数据有限.
- 该ANITA研究解决了这些差距在一个大型的,多中心的意大利队列.
研究的目的:
- 评估扩展分子谱 (EMP) 在晚期胆管癌 (CCA) 中的现实世界吸收和影响.
- 评估基于分子改变的针对性疗法的患者获取和结果.
- 探索CCA中关键分子驱动因素的预后和预测价值.
主要方法:
- 在10个意大利中心 (2017-2023) 进行了621名晚期CCA患者的观察性研究 (ANITA).
- 分析EMP率,随着时间的推移的趋势,以及获得有针对性的治疗.
- 评估与EMP和向治疗使用有关的整体生存 (OS) 和无进展生存 (PFS).
主要成果:
- 在79.9%的患者中进行了EMP,从2017年至2023年期间的比例显著增加.
- 139名患者有可操作的分子变化 (ESCAT I-III),但只有18.7%的患者接受了匹配的向治疗.
- 接受向治疗的患者与没有 (HR 0.49) 或没有可用EMP (HR 0.34) 的患者相比,显著改善了OS.
- FGFR2融合/重组显示了OS的预后作用,独立于向治疗.
结论:
- 尽管在先进的CCA中增加了EMP的可用性,但获得向治疗的机会仍然不够理想.
- 针对性治疗为CCA患者提供了显著的生存益处.
- 迫切需要制定战略,加强针对性治疗的获取和可用性.

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

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...
