abstract = {Childhood cancer survivors (CCS) exhibit significantly
increased chronic diseases and premature death.
Abnormalities in DNA methylation are associated with
development of chronic diseases and reduced life expectancy.
We investigated the hypothesis that anti-cancer treatments
are associated with long-term DNA methylation changes that
could be key drivers of adverse late health
effects.Genome-wide DNA methylation was assessed using
MethylationEPIC arrays in paired samples (before/after
therapy) from 32 childhood cancer patients. Separately,
methylation was determined in 32 samples from different
adult CCS (mean 22-years post-diagnosis) and compared with
cancer-free controls (n = 284).Widespread DNA methylation
changes were identified post-treatment in childhood cancer
patients, including 146 differentially methylated regions
(DMRs), which were consistently altered in the 32
post-treatment samples. Analysis of adult CCS identified
matching methylation changes at 107/146 of the DMRs,
suggesting potential long-term retention of post-therapy
changes. Adult survivors also exhibited epigenetic age
acceleration, independent of DMR methylation. Furthermore,
altered methylation at the DUSP6 DMR was significantly
associated with early mortality, suggesting altered
methylation may be prognostic for some late adverse health
effects in CCS.These novel methylation changes could serve
as biomarkers for assessing normal cell toxicity in ongoing
treatments and predicting long-term health outcomes in CCS.},
