Objective: To describe psychosocial outcomes among adult siblings of very long‐term childhood cancer survivors (CCS), to compare these outcomes to reference populations and to identify factors associated with siblings' psychosocial outcomes. Methods: Siblings of survivors (diagnosed <18 years old, between 1963 and 2001, >5 years since diagnosis) of the Dutch Childhood Cancer Survivor Study DCCSS‐LATER cohort were invited to complete questionnaires on HRQoL (TNO‐AZL Questionnaire for Adult's HRQoL), anxiety/depression (Hospital Anxiety and Depression Scale), post‐traumatic stress (Self‐Rating Scale for Post‐traumatic Stress Disorder), self‐esteem (Rosenberg Self‐Esteem Scale) and benefit and burden (Benefit and Burden Scale for Children). Outcomes were compared to a reference group if available, using Mann‐Whitney U and chi‐Square tests. Associations of siblings' sociodemographic and CCS' cancer‐related characteristics with the outcomes were assessed with mixed model analysis. Results: Five hundred five siblings (response rate 34%, 64% female, mean age 37.5, mean time since diagnosis 29.5) of 412 CCS participated. Siblings had comparable HRQoL, anxiety and self‐esteem to references with no or small differences (r = 0.08−0.15, p < 0.05) and less depression. Proportions of symptomatic PTSD were very small (0.4%−0.6%). Effect sizes of associations of siblings' sociodemographic and CCS cancer‐related characteristics were mostly small to medium (β = 0.19−0.67, p < 0.05) and no clear trend was found in the studied associated factors for worse outcomes. Conclusions: On the very long‐term, siblings do not have impaired psychosocial functioning compared to references. Cancer‐related factors seem not to impact siblings' psychosocial functioning. Early support and education remain essential to prevent long‐term consequences. [ABSTRACT FROM AUTHOR]

Background: This study compares a comprehensive range of psychosocial outcomes of adult childhood cancer survivors (CCS) to general population‐based references and identifies sociodemographic and medical risk factors. Methods: CCS from the Dutch Childhood Cancer Survivor Study (DCCSS)‐LATER cohort (diagnosed 1963–2001) part 2 (attained age ≥18 years, diagnosed <18 years, ≥5 years since diagnosis) completed the Rosenberg Self‐Esteem Scale, Hospital Anxiety and Depression Scale, Distress Thermometer, Self‐Rating Scale for Post‐Traumatic Stress Disorder, and the Short Form‐36 (Health Related Quality of Life). CCS' scores were compared with references using analysis of variances and logistic regression analysis, controlling for age and sex (p <.05). Risk factors for worse psychosocial outcomes were assessed with regression analyses (p <.05). Results: CCS, N = 1797, mean age 35.4 years, 49.0% female, all ≥15 years since diagnosis, participated. Three percent reported posttraumatic stress disorder because of childhood cancer and 36.6% experienced clinical distress. CCS did not differ from references on self‐esteem and anxiety but were less depressed (d = −.25), and scored poorer on all health‐related quality of life scales, except for bodily pain (.01 ≤ d ≥ −.36). Female sex, lower educational attainment, not being in a relationship, and being unemployed were negatively associated with almost all psychosocial outcomes. Except for a central nervous system tumor diagnosis, few medical characteristics were associated with psychosocial outcomes. Conclusion: CCS appear resilient regarding mental health but have slightly poorer health‐related quality of life than references. Sociodemographic characteristics and central nervous system tumors were related to most psychosocial outcomes, but no clear pattern was observed for other medical factors. Future studies should address additional factors in explaining CCS' psychosocial functioning, such as coping, social support, and physical late effects. Adult childhood cancer survivors appear resilient regarding mental health but have slightly poorer health‐related quality of life than reference patients. Sociodemographic characteristics and central nervous system tumors were related to most psychosocial outcomes, but no clear pattern was observed for other medical factors. [ABSTRACT FROM AUTHOR]

Objective: To describe health‐related quality of life (HRQoL), post‐traumatic stress and post‐traumatic growth of parents of long‐term survivors of childhood cancer (CCS) and study associated factors. Methods: Parents of survivors of the Dutch Childhood Cancer Survivor Study LATER cohort below 30 years and diagnosed 1986–2001 were invited to complete the TNO‐AZL Questionnaire for Adult's HRQoL (e.g., sleep and aggressive emotions), Self‐Rating Scale for Post‐traumatic Stress Disorder, Post‐traumatic Growth Inventory, and Illness Cognition Questionnaire. HRQoL domain scores were compared to references using Mann‐Whitney U tests. Correlations between post‐traumatic stress, growth and HRQoL were evaluated. Medical characteristics of their child and illness cognitions were studied as associated factors of HRQOL, post‐traumatic stress and growth. p < 0.05 was considered statistically significant. Results: Parents (n = 661 of n = 448 survivors, 56% female, mean time since child's diagnosis: 21.3 [SD: 3.3] years) reported better HRQoL in social functioning and aggressive emotions than references (r =.08–0.17). Mothers additionally reported better HRQoL in pain, daily activities, sexuality, vitality, positive and depressive emotions (r =.07–0.14). Post‐traumatic stress was symptomatic in 3%, and associated with worse HRQoL (r = −0.27–0.48). Post‐traumatic growth was positively associated to post‐traumatic stress and better HRQoL (r = 0.09–0.12). Cancer recurrence was associated to better HRQoL (β = 0.37–0.46). Acceptance illness cognitions were associated to better (β = 0.12–0.25), and helplessness to worse outcomes (β = 0.14–0.38). Conclusions: HRQoL of parents of young adult survivors of CCS is comparable to references or slightly better. Only a small proportion reports symptomatic post‐traumatic stress. Improving acceptance and reducing feelings of helplessness may provide treatment targets for parents with psychosocial problems. [ABSTRACT FROM AUTHOR]

Background: The objective of this study was to compare the health‐related quality of life (HRQOL) of Dutch adult male and female childhood cancer survivors (CCSs) to general population references and to study medical determinants. Methods: CCSs from the Dutch Childhood Cancer Survivor Study LATER cohort (1963‐2001) part 2, who were 18 years old or older (time since diagnosis ≥ 5 years), were invited to complete the TNO‐AZL Questionnaire for Adult Health‐Related Quality of Life. Domain scores and proportions of CCSs with impaired HRQOL (score < 25th percentile of the reference scores) were compared with references via Mann‐Whitney U tests and logistic regression analyses corrected for age and sex (P <.004). Interactions of group with sex were included if they were significant (P <.05). Moreover, medical determinants were analyzed with multivariable logistic regression analyses. Results: HRQOL scores for 1766 CCSs (mean age, 35.9 years [standard deviation, 9.4 years]; male, 51%; response rate, 71%) differed from references on most domains with small effect sizes. Both male and female CCSs were more often impaired in gross and fine motor functioning, cognitive functioning, sleep, and vitality with odds ratios (ORs) > 1.4. In addition, female CCSs were more often impaired in daily activities, pain, and sexuality (ORs, 1.4‐1.9) and were less often aggressive (OR, 0.6). CCCs of central nervous system (CNS) tumors, bone tumors, and retinoblastoma and those with cranial, abdominopelvic, or lower extremity radiotherapy were at increased risk of impairment in 1 or more domains. Conclusions: Dutch adult CCSs, especially females, have impaired HRQOL in several domains; this is most pronounced in cognitive functioning. The vulnerabilities of subgroups at risk, such as CCSs of CNS tumors, were confirmed. Surveillance of HRQOL and multidisciplinary survivor care are recommended. Lay Summary: The health‐related quality of life in a Dutch nationwide cohort of 1766 survivors of childhood cancer was studied.Survivors of childhood cancer were found to have lower health‐related quality of life in several domains (eg, motor functioning and vitality) in comparison with the general population.They most often reported low cognitive functioning (eg, memory and attention).Females had low health‐related quality of life in more domains than males.Survivors of brain tumors had low health‐related quality of life in most domains.Monitoring health‐related quality of life regularly and collaborating between disciplines in survivor care is recommended. Dutch adult survivors of childhood cancer, especially females and central nervous system tumor survivors, have impaired health‐related quality of life in several domains; this is most pronounced in cognitive functioning. Surveillance of health‐related quality of life and multidisciplinary survivor care are recommended. [ABSTRACT FROM AUTHOR]
