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...

科学领域:

  • 在瘤学瘤学.
  • 放射学 放射学是一门学科.
  • 机器学习 机器学习

背景情况:

  • 新辅助化疗 (NAC) 是局部晚期乳腺癌 (LABC) 的关键治疗方法.
  • 在治疗前预测患者对NAC的反应对于优化治疗策略至关重要.
  • 准确的预测有助于定制治疗计划并改善患者的治疗结果.

研究的目的:

  • 开发一种机器学习管道,用于预测LABC患者对NAC的瘤反应.
  • 为了评估结合临床和放射学计算机断层扫描 (CT) 功能的疗效,以预测治疗反应.

主要方法:

  • 采用了混合特征选择方法,结合了基于波器的技术 (矩阵等级定理) 和带有支持矢量机 (SVM) 分类器的遗传算法.
  • 由于特征与样本比率很高 (117名患者有858个特征),因此进行了尺寸缩小.
  • 用三种模型的平衡精度,精度,AUC和F1得分来评估性能:仅临床特征,仅放射性CT特征和两者的组合.

主要成果:

  • 这项研究包括117名LABC患者 (平均年龄52±11岁),其中82人对NAC有反应,35人没有反应.
  • 使用临床和CT放射学特征的组合模型以0.88.8的精度实现了最高的性能.
  • 这种综合方法显示出优越的预测能力,而不是单独使用任何一个特征集.

结论:

  • 临床特征和CT放射性特征的结合为预测LABC患者的NAC治疗反应提供了有效的策略.
  • 这种机器学习方法对个性化医疗在乳腺癌治疗中具有前途.
  • 需要对更大的队列进行进一步验证,以证实这些发现.
