概括
精确瘤学在胰腺癌方面的进展揭示了关键的分子标. 分子分析指导了针对这种致命恶性瘤的个性化治疗策略,改善了患者的治疗结果.
科学领域:
- 在瘤学瘤学.
- 基因组学就是基因组学.
- 精准医学是一门精准的医学.
背景情况:
- 胰腺管道腺癌 (PDAC) 是一种高度致命的癌症,治疗选择有限.
- 下一代测序已经确定了关键的分子目标,推动了PDAC的攻击性.
- 了解基因组环境对于开发有效的精密治疗至关重要.
研究的目的:
- 审查胰腺癌当前的分子标和治疗策略.
- 突出分子分析在推进PDAC的精密瘤学中的作用.
- 讨论基因突变和共同突变对治疗选择和预后的影响.
主要方法:
- 审查下一代测序数据和临床试验结果.
- 分析PDAC中常见和罕见的可采取行动的变化.
- 在PDAC亚组中评估向疗法和免疫疗法的疗效.
主要成果:
- 基尔斯顿大鼠肉瘤病毒瘤基因同类基因 (KRAS) 突变很普遍,但在很大程度上是无法治疗的,正在研究新型抑制剂.
- BRCA1/2突变使PDAC对剂和PARP抑制剂产生敏感性.
- 罕见的变化 (BRAF V600,NTRK,FGFR2,RET融合) 在瘤不可知试验中有利于选定的患者.
- 由于瘤突变负担较低和不匹配修复缺陷,免疫疗法的有效性有限.

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...

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.
