基于临床肿瘤样本DNA甲基化组的机器学习分类器预测放疗反应
Machine learning classifiers based on DNA methylation profiles of clinical tumor samples predict radiotherapy responses
摘要
Abstract
Objective To construct a machine learning model using DNA methylation features to pre-dict radiotherapy(RT)response in cancer patients.Methods By integrating and analyzing 10 types of cancer and whole-genome DNA methylation data alongside RT efficacy data from 843 patients,differentially methyla-ted sites(DMSs)significantly associated with radio sensitivity were identified.Machine learning classifier models were developed based on these characteristic DMSs.Results The machine learning classifier construc-ted based on methylation signals from multiple CpG sites(AUC=0.889-1.000)was significantly superior to a single DMS(AUC=0.594-0.956,P<0.001)in distinguishing between radio-sensitive and radio-resistant patients.The model could also accurately predict the overall survival period of patients.Conclusion The ma-chine learning model based on DNA methylome features has clinical application value in predicting the efficacy and prognosis of RT.关键词
