概括
这项研究表明,患有早期乳腺癌和Magee方程得分为18或以下的绝经后妇女可能不需要进行Oncotype Dx®测试. 这种方法可以降低医疗保健成本和患者的财务毒性.
科学领域:
- 在瘤学瘤学.
- 基因组学就是基因组学.
- 卫生经济学 卫生经济学
背景情况:
- 型Dx®试验是一种用于早期,HR+,HER2乳腺癌预后和化疗益处预测的标准工具.
- 像Oncotype Dx®这样的基因组测试可以给患者和医疗保健系统带来巨大的财务负担.
- 确定具有成本效益的替代方案对于管理治疗决策和资源分配至关重要.
研究的目的:
- 评估在早期乳腺癌患者的特定子组中省略Oncotype Dx®测试的可行性.
- 探索Magee方程2 (ME2) 评分作为型Dx®的潜在替代品的实用性.
- 通过使用替代评分方法,评估降低成本和降低财务毒性的潜力.
主要方法:
- 在2015-2020年间诊断出结节阴性,HR+,HER2-乳腺癌的126名绝经后妇女的回顾性分析.
- 计算所有患者的梅吉方程2 (ME2) 评分.
- 确定Oncotype Dx®复发得分和ME2得分之间的相关性.
主要成果:
- 在Oncotype Dx®和ME2得分之间发现了统计学上显著的相关性 (r=0.3442,p<0.0001).
- 型Dx®平均得分为12,ME2平均得分为13.6.
- 在平均5.03年的随访期间,没有观察到局部或远部复发或与乳腺癌相关的死亡.
结论:
- 省略瘤型Dx®检测可能是早期乳腺癌和ME2得分≤18.8的绝经后妇女的安全.
- 使用ME2等可比工具可能会降低财务毒性和系统成本.
- 建议对更大的队列进行进一步的研究,以验证这些发现.

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...
