Physical performance limitations in adolescent and adult survivors of childhood cancer and their siblings.

ABSTRACT:

Purpose

This study investigates physical performance limitations for sports and daily activities in recently diagnosed childhood cancer survivors and siblings.

Methods

The Swiss Childhood Cancer Survivor Study sent a questionnaire to all survivors (? 16 years) registered in the Swiss Childhood Cancer Registry, who survived >5 years and were diagnosed 1976-2003 aged <16 years. Siblings received similar questionnaires. We assessed two types of physical performance limitations: 1) limitations in sports; 2) limitations in daily activities (using SF-36 physical function score). We compared results between survivors diagnosed before and after 1990 and determined predictors for both types of limitations by multivariable logistic regression.

Results

The sample included 1038 survivors and 534 siblings. Overall, 96 survivors (9.5%) and 7 siblings (1.1%) reported a limitation in sports (Odds ratio 5.5, 95%CI 2.9-10.4, p<0.001), mainly caused by musculoskeletal and neurological problems. Findings were even more pronounced for children diagnosed more recently (OR 4.8, CI 2.4-9.6 and 8.3, CI 3.7-18.8 for those diagnosed <1990 and ? 1990, respectively; p=0.025). Mean physical function score for limitations in daily activities was 49.6 (CI 48.9-50.4) in survivors and 53.1 (CI 52.5-53.7) in siblings (p<0.001). Again, differences tended to be larger in children diagnosed more recently. Survivors of bone tumors, CNS tumors and retinoblastoma and children treated with radiotherapy were most strongly affected.

Conclusion

Survivors of childhood cancer, even those diagnosed recently and treated with modern protocols, remain at high risk for physical performance limitations. Treatment and follow-up care should include tailored interventions to mitigate these late effects in high-risk patients.

Project description:ImportanceCertain cancer therapies are risk factors for epigenetic age acceleration (EAA) among survivors of childhood cancer, and EAA is associated with chronic health conditions (CHCs). However, small numbers of younger survivors (aged <20 years) previously evaluated have limited the ability to calculate EAA among this age group.ObjectiveTo evaluate the change rate of epigenetic age (EA) and EAA in younger compared with older survivors and the possible association of EAA with early-onset obesity (aged <20 years), severity/burden of CHCs, and late mortality (>5 years from cancer diagnosis).Design, setting, and participantsStudy participants were from the St Jude Lifetime Cohort, initiated in 2007 with ongoing follow-up. The present study was conducted from April 17, 2022, to March 23, 2023. Survivors in this cohort of European ancestry with DNA methylation data were included. Cross-sectional annual changes in EA and EAA were compared across 5 different chronologic age groups: age 0 to 9 (children), 10 to 19 (adolescents), 20 to 34 (younger adults), 35 to 49 (middle-aged adults), and greater than or equal to 50 (older adults) years. Logistic regression evaluated the association between EAA and early-onset obesity or severity/burden of CHCs. Cox proportional hazards regression assessed the association between EAA and late mortality.Main outcomes and measuresEarly-onset obesity, severity/burden of CHCs (graded using the Common Terminology Criteria for Adverse Events (grade 1, mild; 2, moderate; 3, severe/disabling; 4, life-threatening) and were combined into high vs low severity/burden based on frequency and grade), and late mortality were the outcomes based on follow-up until April 2020. Expanded DNA methylation profiling increased the number of survivors younger than 20 years (n = 690). Epigenetic age was calculated primarily using the Levine clock, and EAA was derived from least squares regression of EA against chronologic age and was standardized to a z score (Levine EEA).ResultsAmong 2846 participants (median age, 30.3 [IQR, 9.3-41.5] years; 53% males), the cross-sectional annual change in EA_Levine was higher in children (1.63 years) and adolescents (1.14 years), and the adjusted least-squares mean of Levine EEA was lower in children (-0.22 years) and older adults (-1.70 years). Each 1-SD increase in Levine EEA was associated with increased risk of developing early-onset obesity (odds ratio [OR], 1.46; 95% CI, 1.19-1.78), high severity/burden of CHCs (OR, 1.13; 95% CI, 1.03-1.24), and late mortality (hazard ratio, 1.75; 95% CI, 1.35-2.26).Conclusions and relevanceThe findings of this study suggest that EAA measured in children and adolescent survivors of childhood cancer is associated with early-onset obesity, severity/burden of all CHCs, and late mortality. Evaluating EAA may help identify survivors of childhood cancer at increased risk for early-onset obesity, morbidity in general, and mortality.

Project description:BackgroundBeyond survival of nowadays >80%, modern childhood cancer treatment strives to preserve long-term health and quality of life. However, the majority of today's survivors suffer from short- and long-term adverse effects such as cardiovascular and pulmonary diseases, obesity, osteoporosis, fatigue, depression, and reduced physical fitness and quality of life. Regular exercise can play a major role to mitigate or prevent such late-effects. Despite this, there are no data on the effects of regular exercise in childhood cancer survivors from randomized controlled trials (RCTs). Primary outcome of the current RCT is therefore the effect of a 12-months exercise program on a composite cardiovascular disease risk score in childhood cancer survivors. Secondary outcomes are single cardiovascular disease risk factors, glycaemic control, bone health, body composition, physical fitness, physical activity, quality of life, mental health, fatigue and adverse events (safety).MethodsA total of 150 childhood cancer survivors aged ≥16 years and diagnosed ≥5 years prior to the study are recruited from Swiss paediatric oncology clinics. Following the baseline assessments patients are randomized 1:1 into an intervention and control group. Thereafter, they are seen at month 3, 6 and 12 for follow-up assessments. The intervention group is asked to add ≥2.5 h of intense physical activity/week, including 30 min of strength building and 2 h of aerobic exercises. In addition, they are told to reduce screen time by 25%. Regular consulting by physiotherapists, individual web-based activity diaries, and pedometer devices are used as motivational tools for the intervention group. The control group is asked to keep their physical activity levels constant.DiscussionThe results of this study will show whether a partially supervised exercise intervention can improve cardiovascular disease risk factors, bone health, body composition, physical activity and fitness, fatigue, mental health and quality of life in childhood cancer survivors. If the program will be effective, all relevant information of the SURfit physical activity intervention will be made available to interested clinics that treat and follow-up childhood cancer patients to promote exercise in their patients.Trial registrationProspectively registered in clinicaltrials.gov [ NCT02730767 ], registration date: 10.12.2015.

Project description:BackgroundThis study estimates the prevalence and identifies predictors of psychoactive medication use in adolescent survivors of childhood cancer (aged 12-18 years) and its associations with functional outcomes at young adulthood (aged 18-28 years).MethodsThis retrospective cohort study includes 5665 adolescent survivors of childhood cancer at no less than 5 years postdiagnosis (53.8% male, median age = 15 years, interquartile range [IQR] = 13-16 years) and 921 adolescent sibling controls. Parent-reported psychoactive medication use during adolescence was collected at baseline. After a median of 8 years, functional outcomes and social attainment were self-reported during adulthood (n = 3114, median age = 22 years, IQR = 20-24 years). Multivariable log-binomial models evaluated associations among risk factors, medication use, and adult outcomes.ResultsHigher prevalence of psychoactive medication use was reported in survivors compared with siblings (18.3% vs 6.6%; 2-sided P < .001), with trends for increasing antidepressant and stimulant use in recent treatment eras. After adjusting for cancer treatment and baseline cognitive problems, psychoactive medication use during adolescence was associated with impaired task efficiency (relative risk [RR] = 1.20, 95% confidence interval [CI] = 1.01 to 1.43) and memory (RR = 1.27, 95% CI = 1.05 to 1.52) during adulthood. Survivors who reported continued use of medications from adolescence to adulthood demonstrated poorer emotional regulation (RR = 1.68, 95% CI = 1.24 to 2.27) and organization (RR = 1.82, 95% CI = 1.28 to 2.59) compared with nonusers. Adolescent opioid use was associated with somatization symptoms (RR = 1.72, 95% CI = 1.09 to 2.73) during adulthood, after adjusting for cancer treatment and baseline behavioral problems. They were also more likely to not complete college (RR = 1.21, 95% CI = 1.04 to 1.41) or work full-time (RR = 1.60, 95% CI = 1.23 to 2.08) compared with nonusers.ConclusionUse of psychoactive medication is more prevalent among adolescent survivors compared with siblings and does not normalize adult outcomes, as evidenced by poorer functional outcomes during young adulthood.
