Abstract 3145: Detection of premature aging among adolescent and young adult osteosarcoma and Ewings sarcoma survivors

Abstract

Abstract BACKGROUND Bone sarcoma survivors are at high risk for multiple chronic diseases at a young age, which can be characterized as premature aging. Bone sarcoma survivors have the highest cumulative incidence of multiple serious chronic conditions according to analysis of the Childhood Cancer Survivor Study 1. Cardiovascular biomarkers can be used to detect CAD, and enable early intervention in asymptomatic patients. METHODS Patients are seen annually at the Sarcoma Survivorship Clinic at the University of Michigan and includes high risk patients over the age of 18 who are at least two years free of disease after treatment completion. Clinical data includes: Blood Pressure, BMI, lipid profile, high sensitivity C-Reactive Protein, and imaging. RESULTS 30% of patients aged 18-39 exhibit elevations in the cardiovascular biomarker hsCRP, in addition to the traditional biologic markers of elevated lipids, hypertension, and BMI at their most recent clinic visit (Table 1). A subset of patients independently evaluated by 2 nuclear cardiologists also show evidence of coronary artery calcifications (CAC), which is considered pathognomonic of CAD. 40% have been diagnosed with 2 or more of the following chronic diseases: dyslipidemia, obesity, renal insufficiency, anxiety and/or depression, pulmonary disease, cardiovascular disease, thyroid dysfunction, hypertension, liver disease, and anemia. CONCLUSION The overall cardiac risk profile among high risk bone sarcoma survivors is characteristic of premature aging. Examining the underlying mechanism of premature aging is essential in this population. Proposed investigation includes alteration of immune pathway as effected by diet, the microbiome, metabolomics, and cellular senescence. REFERENCES: 1.
