Epigenetic Age Acceleration Mediates Treatment Effects on Cardiometabolic and Cardiovascular Risk in Childhood Cancer Survivors.
Background: Childhood cancer survivors are at increased risk for epigenetic age acceleration (EAA) and subsequent morbidities, including cardiometabolic risk factors (CMRFs) and cardiovascular diseases, because of prior genotoxic treatments.
Objectives: The aim of this study was to evaluate the mediating role of EAA in the relationship between cancer treatment exposures and risk for CMRFs and cardiovascular diseases.
Methods: This study included 2,939 5-year survivors from SJLIFE (St. Jude Lifetime Cohort) who underwent DNA methylation profiling using peripheral blood mononuclear cells. EAA was calculated using 3 established epigenetic clocks: DunedinPACE, PCPhenoAge, and GrimAge2. Treatment data, including body region-specific radiotherapy (RT) and chemotherapeutic agents such as anthracyclines and corticosteroids, were abstracted from medical records. Outcomes included 3 CMRFs (abnormal glucose metabolism, hypertension, and obesity) and 2 cardiovascular diseases (cardiomyopathy and myocardial infarction). Mediation analysis was conducted to quantify the extent to which EAA mediated the association between each treatment exposure and each clinical outcome.
Results: EAA partially mediated the associations between abdominal RT and abnormal glucose metabolism (DunedinPACE 35.4%, GrimAge2 16.2%), between abdominal RT (DunedinPACE 25.9%) or anthracyclines (DunedinPACE 12.5%) and hypertension, and between corticosteroids and obesity (DunedinPACE 8.6%). EAA also mediated the associations between heart RT and cardiomyopathy (PCPhenoAge 30.3%, DunedinPACE 19.9%, GrimAge2 14.4%) and myocardial infarction (PCPhenoAge 24.1%, DunedinPACE 15.5%, GrimAge2 13.2%), and anthracyclines and cardiomyopathy (GrimAge2 6.0%, PCPhenoAge 5.2%, DunedinPACE 3.9%).
Conclusions: EAA accounted for a substantial proportion of the association between cancer treatment exposures and risk for CMRFs and cardiovascular diseases. These findings provide insight into biological aging as a potential mechanistic pathway and support the development of interventions targeting accelerated aging to mitigate long-term treatment-related toxicities and reduce premature mortality in this high-risk population.
期刊介绍：
JACC: CardioOncology is a specialized journal that belongs to the esteemed Journal of the American College of Cardiology (JACC) family. Its purpose is to enhance cardiovascular care for cancer patients by publishing high-quality, innovative scientific research and sharing evidence-based knowledge.
The journal aims to revolutionize the field of cardio-oncology and actively involve and educate professionals in both cardiovascular and oncology fields. It covers a wide range of topics including pre-clinical, translational, and clinical research, as well as best practices in cardio-oncology. Key areas of focus include understanding disease mechanisms, utilizing in vitro and in vivo models, exploring novel and traditional therapeutics (across Phase I-IV trials), studying epidemiology, employing precision medicine, and investigating primary and secondary prevention.
Amyloidosis, cardiovascular risk factors, heart failure, and vascular disease are some examples of the disease states that are of particular interest to the journal. However, it welcomes research on other relevant conditions as well.
