概括
生殖系遗传学似乎无法预测芳酶抑制剂在ER阳性乳腺癌中的有效性. 这项研究没有发现与治疗结果相关的经过验证的遗传变异,突出显示需要进一步研究.
科学领域:
- 基因组学就是基因组学.
- 在瘤学瘤学.
- 药物基因组学 药物基因组学
背景情况:
- 在雌激素受体阳性 (ER+) 乳腺癌中辅助芳酶抑制剂 (AI) 治疗的疗效受患者特定因素的影响.
- 在预测人工智能治疗反应方面,生殖系遗传变异的作用仍然在很大程度上未被探索.
研究的目的:
- 研究与内分泌耐药性相关基因的常见生殖系变异与ER+乳腺癌患者接受人工智能治疗的生存结果之间的关联.
主要方法:
- 使用了两阶段候选基因方法,选了753个基因.
- 发现队列分析涉及乳腺癌协会联盟数据库 (n≥90,000例) 与2789名人工智能治疗患者.
- 基于考克斯模型的分析确定了125个与生存终点相关的变异 (p≤1E-04),随后在五个独立队列 (n=8857) 中进行了验证.
主要成果:
- 最初的分析确定了125种生殖系变异,可能与整体,远程无复发和无复发生存相关.
- 然而,随后在五个独立队列中进行的验证分析未能在六个选定的候选变异中复制这些发现.
- 验证失败的潜在原因包括研究和治疗异质性,以及基因组结果研究的局限性.
结论:
- 常见的生殖系遗传变异似乎不是人工智能治疗ER+乳腺癌疗效的可靠预测因素.
- 未来的研究应该专注于前性的纵向研究,以强大的设计来调查内分泌抵抗.
- 了解遗传和非遗传因素的复杂相互作用对于个性化乳腺癌治疗至关重要.

Targeted Cancer Therapies
7.4K
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
3.2K
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...

Combination Therapies and Personalized Medicine
4.8K
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...
