Cancer Survival Analysis01:21

Cancer Survival Analysis

301
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

科学领域:

  • 在瘤学瘤学.
  • 基因组学就是基因组学.
  • 机器学习 机器学习

背景情况:

  • 子宫内膜癌 (EC) 是美国普遍存在的妇科恶性瘤,发病率和死亡率不断增加.
  • 很大比例的EC患者 (15%-20%) 经历了复发尽管标准治疗.
  • 准确预测复发风险对于选择适当的辅助疗法至关重要.

研究的目的:

  • 开发,验证和测试子宫内膜癌复发的预测模型.
  • 利用机器学习 (ML) 和深度学习 (DL) 分析来提高预测准确度.
  • 采用包括临床,病理,基因组和遗传信息在内的全面数据集.

主要方法:

  • 分析了来自瘤研究信息交换网络数据库的数据.
  • 患者被分为低风险,高风险和非子宫内膜组织学组.
  • 多变量模型使用拉索回归,ML (MATLAB) 和DL (TensorFlow) 进行训练,验证和测试,其中包含基因组数据 (microRNA,lncRNA,伪基因表达) 和遗传变异 (SNV,CNV).

主要成果:

  • 最初的临床复发模型显示AUC在56%至70%之间.
  • 实现AUC>80%的模型被选择用于进一步分析:五个低风险组,20个高风险组,20个非子宫内膜组织组.
  • 性能最好的模型包括临床数据,副本数变异 (CNV),伪基因表达和单核酸变异 (SNV).

结论:

  • 基于ML和DL的预测模型显示,与仅依赖临床和病理数据的模型相比,其性能优越.
  • 这些先进的模型有望改善预测子宫内膜癌复发的预测.
  • 需要进一步的前性验证,以确定这些预测模型的临床实用性.
