Frailty and Comorbidities Among Survivors of Adolescent and Young Adult Cancer: A Cross-Sectional Examination of a Hospital-Based Survivorship Cohort.

<bold><italic>Purpose:</italic></bold> Cancer survivors are at increased risk for the early development of age-related chronic medical conditions compared with peers without a history of cancer; however, little is known regarding the burden of these conditions among survivors of adolescent and young adult (AYA) cancers. In response, we sought to determine the prevalence of specific comorbidities and frailty among AYAs (15–39 years old at diagnosis) enrolled in a cancer survivorship cohort. <bold><italic>Methods:</italic></bold> Using a cross-sectional survey of a tertiary medical center-based cancer survivorship cohort, we determined the prevalence of specific comorbidities and frailty using the survey-based FRAIL assessment. In separate models adjusting for age, we estimated prevalence ratios (PRs) for the associations between patient characteristics and (1) any comorbidity and (2) frailty or prefrailty using log-binomial models. <bold><italic>Results:</italic></bold> We identified 271 AYA cancer survivors, most of whom were 30–39 years old at survey (57%). A majority of survivors (<italic>n</italic> = 163, 60%) reported having at least one comorbidity with the most common being depression (28%), anxiety (27%), asthma (17%), high cholesterol (15%), and hypertension (15%). Of the 184 AYA survivors at least 1 year from cancer diagnosis, 19 (10%) were classified as frail and 39 (21%) as prefrail. Survivors who were smokers (PR 2.0, 95% confidence interval [CI]: 1.16–3.56); obese (PR 1.7, 95% CI: 1.10–2.55); uninsured (PR 2.7, 95% CI: 1.63–4.59); or who reported comorbid depression or anxiety (PR 2.4, 95% CI: 1.51–3.67) were more likely to be frail or prefrail. <bold><italic>Conclusions:</italic></bold> The prevalence of frailty and comorbidities is high among AYA cancer survivors suggestive of accelerated aging.
