Identification of a methylomics-associated nomogram for predicting overall survival of stage I-II lung adenocarcinoma.

ABSTRACT: The aim of this paper was to identify DNA methylation based biomarkers for predicting overall survival (OS) of stage I-II lung adenocarcinoma (LUAD) patients. Methylation profile data of patients with stage I-II LUAD from The Cancer Genome Atlas (TCGA) database was used to determine methylation sites-based hallmark for stage I-II LUAD patients' OS. The patients were separated into training and validation datasets by using median risk score as cutoff. Univariate Cox, least absolute shrinkage and selection operator (LASSO) and multivariate Cox analyses were employed to develop a DNA methylation signature for OS of patients with stage I-II LUAD. As a result, an 11-DNA methylation signature was determined to be critically associated with the OS of patients with stage I-II LUAD. Analysis of rec
