Tumor Progression02:07

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

科学领域:

  • 神经瘤学神经瘤学
  • 基因组学就是基因组学.
  • 生物信息学是一种生物信息学.

背景情况:

  • 根据世界卫生组织 (WHO) 的认可,DNA甲基化分析对于分类中枢神经系统 (CNS) 瘤至关重要.
  • 之前的海德堡分类器版本有助于中枢神经系统瘤诊断.
  • 了解中枢神经系统瘤异质性是准确分类的关键.

研究的目的:

  • 引入海德堡中枢神经系统瘤甲基化分类器版本12.8 (v12.8).
  • 将中枢神经系统瘤的分类扩展到子类水平.
  • 为了提高神经瘤学的诊断精度.

主要方法:

  • 在7495个DNA甲基化概况上训练分类器.
  • 使用随机森林算法进行分类.
  • 整合来自大型在线存储库和全球合作的数据.

主要成果:

  • v12.8分类器识别了184个中枢神经系统瘤子类,从91个类显著扩展.
  • 在子类层面实现了95%的准确性.
  • 概率得分为分类提供可靠的信任度.
