概括
在一线先进的固体瘤中,综合基因组分析 (CGP) 对22.7%的患者确定了基于分子的推治疗 (MBRT). 这种精确的方法可以改善治疗结果,并指导随后的抗癌疗法.
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:
- 先进的固体瘤在一线设置中缺乏向治疗.
- 综合基因组分析 (CGP) 为精准医学提供了一个潜在的战略.
研究的目的:
- 评估前期CGP测试在未经化疗治疗的先进固体瘤中的临床实用性和益处.
- 评估整体存活率 (OS),基于分子的推疗法 (MBRT) 吸收率,响应率和无进展生存率 (PFS) 比率.
主要方法:
- 在六家日本医院的172名患者中对CGP (FoundationOne CDx) 的前性评估.
- 临时分析侧重于一线治疗和随后的疗法,以分子瘤委员会建议为指导.
- 终点包括OS,MBRT,整体响应率 (ORR) 和PFS比率 (MBRT上的PFS/第一线治疗中的PFS).
主要成果:
- 没有达到中位数的OS; 22.7%的患者接受了MBRT.
- 第一线ORR在MBRT组 (56.3%) 和非MBRT组 (42.3%) 中较高.
- 第二线MBRT显示中位数PFS比率为1.1,其中33.3%的患者达到比率≥1.3.3.
结论:
- 在先进的固体瘤中进行前期CGP测试是一种临床上有益的策略.
- CGP促进了基于分子的推疗法的选择,可能改善患者的治疗结果.
- 这种方法有助于指导随后在瘤学中的精确抗癌治疗.

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.

Treatment Resistant Cancers
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...
