科学领域:

  • 在瘤学瘤学.
  • 生物信息学是一种生物信息学.
  • 医学诊断 医学诊断 医学诊断

背景情况:

  • 乳头甲状腺癌 (PTC) 具有不同的风险水平,使手术前评估复杂化.
  • 目前PTC手术前风险分层仍然是一个全球性的挑战.
  • 探索包括临床,免疫,遗传和蛋白质组数据在内的多维特征,以改进PTC风险评估.

研究的目的:

  • 开发和验证一种用于乳头甲状腺癌的新型手术前风险评估分类器 (PRAC-PTC).
  • 整合多维特征,以加强PTC手术前风险分层.
  • 评估PRAC-PTC在减少不必要的手术或过度治疗方面的潜力.

主要方法:

  • 开发了一个机器学习模型 (PRAC-PTC),使用来自多维特征的17个变量.
  • 数据包括临床信息,免疫指数,遗传特征 (BRAFV600E突变) 和高通量蛋白质组学.
  • 该模型在发现组 (274名患者) 上进行了训练,并在回顾性 (166名患者) 和前性 (118名患者) 测试组上进行了验证.

主要成果:

  • 在发现集中,PRAC-PTC实现了高性能,AUC为0.925.
  • 外部验证显示AUC为0.787 (追溯) 和0.799 (前).
  • 在PRAC-PTC的帮助下,临床医生的风险预测准确性提高到84.4%和83.5%的测试组.

结论:

  • 通过整合不同的数据类型,PRAC-PTC有效地分层了PTC的手术前风险.
  • 该分类器在多中心回顾和前队列中表现出强的表现.
  • 在PTC管理中,PRAC-PTC有可能减少不必要的手术和过度治疗.
