However, a considerable portion of patients experience recurrence within the first two years following complete resection. Especially suitable prognostic biomarkers are not available that identify patients at high risk for recurrence who may probably benefit from adjuvant treatment. This study aimed to identify methylation markers for early recurrence that may become important tools for the development of new treatment modalities.Genome-wide DNA methylation profiling was performed on 30 stage I lung adenocarcinomas comparing 14 patients with early metastatic recurrence to 16 patients with a long-term relapse-free survival period using methylated-CpG-immunoprecipitation (MCIp) followed by high-throughput next generation sequencing. The differentially methylated regions (DMRs) between the two subgroups were validated for their prognostic value in two independent cohorts using the MassCleave Assay, a high-resolution quantitative methylation analysis.Unsupervised clustering of patients in the discovery cohort based on DMRs identified patients with shorter relapse free survival (HR 2.23; 95 LB - PUB:(DE-HGF)16 C6 - pmid:32272161 DO - DOI:10.1016/j.jtho.2020.03.023 UR - https://inrepo02.dkfz.de/record/154460 ER -
