RESUMO
BACKGROUND: Treatment-related gonadal dysfunction leading to fertility problems is a frequently encountered late effect in childhood cancer survivors (CCSs). This study evaluated reproductive outcomes and reproductive health care utilization among male CCSs compared with male siblings. METHODS: A nationwide cohort study was conducted as part of the Dutch Childhood Cancer Survivor LATER study part 1, a questionnaire and linkage study. A questionnaire addressing reproductive outcomes and reproductive health care was completed by 1317 male CCSs and 407 male siblings. A total of 491 CCSs and 185 siblings had a previous or current desire for children and were included in this study. RESULTS: Fewer CCSs had biological children compared with siblings (65% vs. 88%; p < .001). The type of conception by men who fathered a child was comparable between CCSs and siblings (spontaneous conception of 90% of both groups; p = .86). The percentage of men who had consulted a reproductive specialist because of not siring a pregnancy was higher in CCSs compared with siblings (34% vs. 12%; p < .001). Following consultation, fewer CCSs underwent assisted reproductive techniques (ART) compared with siblings (41% vs. 77%; p = .001). After ART, fewer CCSs fathered a child compared with siblings (49% vs. 94%; p = .001). CONCLUSIONS: More male survivors consult a reproductive specialist, but fewer survivors undergo ART and father a child after ART compared with siblings. This insight is important for understanding potential problems faced by survivors regarding family planning and emphasizes the importance of collaboration between oncologists and reproductive specialists.

BACKGROUND: The objective of this study was to examine the prevalence of unhealthy lifestyle behaviors, overweight, and obesity in Dutch childhood cancer survivors (CCSs) compared with sibling controls and the Dutch general population. Other aims were to assess associated factors of unhealthy lifestyle behaviors, overweight, and obesity and to identify subgroups of CCSs at risk for these unhealthy statuses. METHODS: The authors included 2253 CCSs and 906 siblings from the Dutch Childhood Cancer Survivor Study-Late Effects After Childhood Cancer cohort, part 1, and added data from the Dutch general population. Questionnaire data were collected on overweight and obesity (body mass index >25.0 kg/m2), meeting physical activity guidelines (>150 minutes per week of moderate or vigorous exercises), excessive alcohol consumption (>14 and >21 alcoholic consumptions per week for women and men, respectively), daily smoking, and monthly drug use. Multivariable logistic regression analyses and two-step cluster analyses were performed to examine sociodemographic-related, health-related, cancer-related, and treatment-related associated factors of unhealthy lifestyle behaviors and to identify subgroups of CCSs at risk for multiple unhealthy behaviors. RESULTS: CCSs more often did not meet physical activity guidelines than their siblings (30.0% vs. 19.3%; p < .001). Married as marital status, lower education level, nonstudent status, and comorbidities were common associated factors for a body mass index ≥25.0 kg/m2 and insufficient physical activity, whereas male sex and lower education were shared associated factors for excessive alcohol consumption, daily smoking, and monthly drug use. A subgroup of CCSs was identified as excessive alcohol consumers, daily smokers, and monthly drug users. CONCLUSIONS: The current results emphasize the factors associated with unhealthy behaviors and the potential identification of CCSs who exhibit multiple unhealthy lifestyle behaviors.

BACKGROUND: The aim of this study is to evaluate how cumulative burden of clinically relevant, self-reported outcomes in childhood cancer survivors (CCSs) compares to a sibling control group and to explore how the burden corresponds to levels of care proposed by existing risk stratifications. METHODS: The authors invited 5925 5-year survivors from the Dutch Childhood Cancer Survivor Study (DCCSS LATER) cohort and their 1066 siblings to complete a questionnaire on health outcomes. Health outcomes were validated by self-reported medication use or medical record review. Missing data on clinically relevant outcomes in CCSs for whom no questionnaire data were available were imputed with predictive mean matching. We calculated the mean cumulative count (MCC) for clinically relevant outcomes. Furthermore, we calculated 30-year MCC for groups of CCSs based on primary cancer diagnosis and treatment, ranked 30-year MCC, and compared the ranking to levels of care according to existing risk stratifications. RESULTS: At median 18.5 years after 5-year survival, 46% of CCSs had at least one clinically relevant outcome. CCSs experienced 2.8 times more health conditions than siblings (30-year MCC = 0.79; 95% confidence interval [CI], 0.74-0.85 vs. 30-year MCC = 0.29; 95% CI, 0.25-0.34). CCSs' burden of clinically relevant outcomes consisted mainly of endocrine and vascular conditions and varied by primary cancer type. The ranking of the 30-year MCC often did not correspond with levels of care in existing risk stratifications. CONCLUSIONS: CCSs experience a high cumulative burden of clinically relevant outcomes that was not completely reflected by current risk stratifications. Choices for survivorship care should extend beyond primary tumor and treatment parameters, and should consider also including CCSs' current morbidity.

Juvenile myelomonocytic leukaemia (JMML) is characterized by gene variants that deregulate the RAS signalling pathway. Children with neurofibromatosis type 1 (NF-1) carry a defective NF1 allele in the germline and are predisposed to JMML, which presumably requires somatic inactivation of the NF1 wild-type allele. Here we examined the two-hit concept in leukaemic cells of 25 patients with JMML and NF-1. Ten patients with JMML/NF-1 exhibited a NF1 loss-of-function variant in combination with uniparental disomy of the 17q arm. Five had NF1 microdeletions combined with a pathogenic NF1 variant and nine carried two compound-heterozygous NF1 variants. We also examined 16 patients without clinical signs of NF-1 and no variation in the JMML-associated driver genes PTPN11, KRAS, NRAS or CBL (JMML-5neg) and identified eight patients with NF1 variants. Three patients had microdeletions combined with hemizygous NF1 variants, three had compound-heterozygous NF1 variants and two had heterozygous NF1 variants. In addition, we found a high incidence of secondary ASXL1 and/or SETBP1 variants in both groups. We conclude that the clinical diagnosis of JMML/NF-1 reliably indicates a NF1-driven JMML subtype, and that careful NF1 analysis should be included in the genetic workup of JMML even in the absence of clinical evidence of NF-1.

INTRODUCTION: The aim of the current study was to investigate whether subtypes of chronic fatigue (CF) can be identified in childhood cancer survivors (CCS), and if so, to determine the characteristics of participants with a specific subtype. METHODS: Participants were included from the nationwide DCCSS LATER cohort. The Checklist Individual Strength (CIS) was completed to assess fatigue. Participants with CF (scored ≥35 on the fatigue severity subscale and indicated to suffer from fatigue for ≥6 months) were divided into subgroups using two-step cluster analysis based on the CIS concentration, motivation, and physical activity subscales. Differences between groups on demographics, psychosocial, lifestyle, and treatment-related variables were determined using ANOVA and chi-square analyses (univariable) and multinomial regression analysis (multivariable). RESULTS: A total of 1910 participants participated in the current study (n = 450 with CF; n = 1460 without CF). Three CF subgroups were identified: Subgroup 1 (n = 133, 29% of participants) had CF with problems in physical activity; Subgroup 2 (n = 111, 25% of participants) had CF with difficulty concentrating; and Subgroup 3 (n = 206, 46% of participants) had multi-dimensional CF. Compared to Subgroup 1, Subgroup 2 more often reported sleep problems, limitations in social functioning, and less often have more than two comorbidities. Subgroup 3 more often reported depression, sleep problems, a lower self-esteem, and limitations in social functioning and a lower educational level compared to Subgroup 1. CONCLUSION: Different subgroups of CCS with CF can be identified based on fatigue dimensions physical activity, motivation and concentration. Results suggest that different intervention strategies, tailored for each subgroup, might be beneficial.

PURPOSE: Splenectomy might be a risk factor for valvular heart disease (VHD) in adult Hodgkin lymphoma survivors. As this risk is still unclear for childhood cancer survivors (CCS), the aim of this study is to evaluate the association between treatments affecting splenic function (splenectomy and radiotherapy involving the spleen) and VHD in CCS. METHODS: CCS were enrolled from the DCCSS-LATER cohort, consisting of 6,165 five-year CCS diagnosed between 1963 and 2002. Symptomatic VHD, defined as symptoms combined with a diagnostic test indicating VHD, was assessed from questionnaires and validated using medical records. Differences in the cumulative incidence of VHD between CCS who received treatments affecting splenic function and CCS who did not were assessed using the Gray test. Risk factors were analyzed in a multivariable Cox proportional hazards model. RESULTS: The study population consisted of 5,286 CCS, with a median follow-up of 22 years (5-50 years), of whom 59 (1.1%) had a splenectomy and 489 (9.2%) radiotherapy involving the spleen. VHD was present in 21 CCS (0.4%). The cumulative incidence of VHD at the age of 40 years was significantly higher in CCS who received treatments affecting splenic function (2.7%, 95% confidence interval (CI) 0.4%-4.9%) compared with CCS without (0.4%, 95% CI 0.1%-0.7%) (Gray's test, p = 0.003). Splenectomy was significantly associated with VHD in a multivariable analysis (hazard ratio 8.6, 95% CI 3.1-24.1). CONCLUSIONS AND IMPLICATIONS: Splenectomy was associated with VHD. Future research is needed to determine if CCS who had a splenectomy as part of cancer treatment might benefit from screening for VHD.
RESUMO
BACKGROUND: Knowledge of the desire for children among childhood cancer survivors (CCSs) is scarce. This study evaluated the desire for children in male CCSs in comparison with male siblings. METHODS: A nationwide cohort study was conducted as part of the Dutch Childhood Cancer Survivor Study LATER study: 1317 male CCSs and 407 male sibling controls completed a questionnaire addressing the desire for children. Logistic regression analyses were used to explore the independent association between survivorship status and the desire for children. Furthermore, additional analyses were performed to identify which cancer-related factors were associated with the desire for children in male CCSs. RESULTS: After adjustments for the age at assessment, the percentage of men who had a desire for children was significantly lower among CCSs compared with the siblings (74% vs. 82%; odds ratio [OR], 0.61; 95% CI, 0.46-0.82; p = .001). The association between survivorship status and the desire for children was attenuated after adjustments for marital status, level of education, and employment status (OR, 0.83; 95% CI, 0.61-1.14; p = .250). The percentage of men who had an unfulfilled desire for children remained significantly higher among CCSs compared with the siblings after adjustments for sociodemographic factors (25% vs. 7%; OR, 5.14; 95% CI, 2.48-10.64; p < .001). CONCLUSIONS: The majority of male CCSs have a desire for children. The likelihood of having to deal with an unfulfilled desire for children is 5 times higher among CCSs compared with their siblings. This insight is important for understanding the needs and experienced problems of CCSs regarding family planning and fertility issues.

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.

Acute graft-versus-host-Disease (aGVHD) is a major cause of morbidity and mortality after allogeneic hematopoietic cell transplantation (HCT). We previously showed that early CD4+ T-cell immune reconstitution (IR; CD4+ IR) predicts survival after HCT. Here, we studied the relation between CD4+ IR and survival in patients developing aGVHD. Pediatric patients undergoing first allogeneic HCT at University Medical Center Utrecht (UMC)/Princess Máxima Center (PMC) or Memorial Sloan Kettering Cancer Center (MSK) were included. Primary outcomes were nonrelapse mortality (NRM) and overall survival (OS), stratified for aGVHD and CD4+ IR, defined as ≥50 CD4+ T cells per µL within 100 days after HCT or before aGVHD onset. Multivariate and time-to-event Cox proportional hazards models were applied, and 591 patients (UMC/PMC, n = 276; MSK, n = 315) were included. NRM in patients with grade 3 to 4 aGVHD with or without CD4+ IR within 100 days after HCT was 30% vs 80% (P = .02) at UMC/PMC and 5% vs 67% (P = .02) at MSK. This was associated with lower OS without CD4+ IR (UMC/PMC, 61% vs 20%; P = .04; MSK, 75% vs 33%; P = .12). Inadequate CD4+ IR before aGVHD onset was associated with significantly higher NRM (74% vs 12%; P < .001) and inferior OS (24% vs 78%; P < .001). In this retrospective analysis, we demonstrate that early CD4+ IR, a simple and robust marker predictive of outcomes after HCT, is associated with survival after moderate to severe aGVHD. This association must be confirmed prospectively but suggests strategies to improve T-cell recovery after HCT may influence survival in patients developing aGVHD.

OBJECTIVES: Childhood cancer may negatively impact childhood cancer survivors' (CCS) sexuality. However, this is an understudied research area. We aimed to describe the psychosexual development, sexual functioning and sexual satisfaction of CCS, and identify determinants for these outcomes. Secondarily, we compared the outcomes of a subsample of emerging adult CCS to the Dutch general population. METHODS: From the Dutch Childhood Cancer Survivor Study LATER cohort (diagnosed 1963-2001), 1912 CCS (18-71 years, 50.8% male) completed questions on sexuality, psychosocial development, body perception, mental and physical health. Multivariable linear regressions were used to identify determinants. Sexuality of CCS age 18-24 (N = 243) was compared to same-aged references using binomial tests and t-tests. RESULTS: One third of all CCS reported hindered sexuality due to childhood cancer, with insecure body the most often reported reason (44.8%). Older age at study, lower education, surviving central nervous system cancer, poorer mental health and negative body perception were identified as determinants for later sexual debut, worse sexual functioning and/or sexual satisfaction. CCS age 18-24 showed significantly less experience with kissing (p = 0.014), petting under clothes (p = 0.002), oral (p = 0.016) and anal sex (p = 0.032) when compared to references. No significant differences with references were found for sexual functioning and sexual satisfaction, neither among female CCS nor male CCS age 18-24. CONCLUSIONS: Emerging adult CCS reported less experience with psychosexual development, but similar sexual functioning and sexual satisfaction compared to references. We identified determinants for sexuality, which could be integrated in clinical interventions for CCS at risk for reduced sexuality.

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 (ß = 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.

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 (ß = 0.37-0.46). Acceptance illness cognitions were associated to better (ß = 0.12-0.25), and helplessness to worse outcomes (ß = 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.

BACKGROUND: Childhood cancer survivors face late health problems; despite advances in research, details on risk remain unclear. We describe the methodological aspects of the Dutch Childhood Cancer Survivor Study (DCCSS) cross-sectional clinical study (LATER 2 study). PROCEDURE: From the multi-center DCCSS LATER cohort of 6165 five-year survivors diagnosed during 1963-2001, we invited 4735 eligible survivors in 2016, as well as siblings and parents of survivors. Gaps in evidence identified during development of surveillance guidelines were translated into clinical research questions for 16 outcome-specific subprojects. The regular care visit to the LATER outpatient clinic forms the backbone of outcome assessment complemented with research-defined measurements (physical examination, clinical tests, questionnaires). Furthermore, blood/saliva samples were taken for deoxyribonucleic acid (DNA) extraction. RESULTS: In total, 2519 (53.2%) survivors participated in the LATER 2 study. When comparing participants with nonparticipants, we observed that males, CNS survivors, and those treated with surgery only were less likely to participate. Of the participating survivors, 49.3% were female. Median time since childhood cancer diagnosis was 26.9 years (range 14.8-54.7 years) and median attained age was 34.4 years (range 15.4-66.6 years). CONCLUSIONS: The high-quality data generated in the LATER 2 study will provide valuable insights into risks of and risk factors for clinical and physical and psychosocial health outcomes and factors for early recognition of those health outcomes in long-term childhood cancer survivors. This will contribute to fill in important gaps in knowledge and improve the quality of life and care for childhood cancer survivors.

PURPOSE: The present study aimed to determine the prevalence of self-reported oral problems and the oral health-related quality of life (OHRQoL) in childhood cancer survivors (CCS). METHODS: Patient and treatment characteristics of CCS have been collected in a cross-sectional study, part of the multidisciplinary DCCSS-LATER 2 Study. To assess self-reported oral health problems and dental problems, CCS filled out the 'Toegepast-Natuurwetenschappelijk Onderzoek' (TNO) oral health questionnaire. OHRQoL was assessed by the Dutch version of the Oral Health Impact Profile-14 (OHIP-14). Prevalences were compared with two comparison groups from the literature. Univariable and multivariable analyses were performed. RESULTS: A total of 249 CCS participated in our study. The OHIP-14 total score had a mean value of 1.94 (sd 4.39), with a median score of 0 (range 0-29). The oral problems 'oral blisters/aphthae' (25.9%) and 'bad odor/halitosis' (23.3%) were significantly more often reported in CCS than in comparison groups (12% and 12%, respectively). The OHIP-14 score was significantly correlated with the number of self-reported oral health problems (r = .333, p<0.0005) and dental problems (r = .392, p <0.0005). In multivariable analysis, CCS with a shorter time since diagnosis (10-19 years vs. ≥30 years) had a 1.47-fold higher risk of ≥1 oral health problem. CONCLUSION: Though the perceived oral health is relatively good, oral complications following childhood cancer treatment are prevalent in CCS. This underlines that attention to impaired oral health and awareness on this topic is mandatory and regular visits to the dentist should be a part of long-term follow-up care.

This investigation aimed to evaluate glomerular dysfunction among childhood cancer survivors in comparison with matched controls from the general population. In the Dutch Childhood Cancer Survivor Study (DCCSS)-LATER 2 kidney analysis, a nationwide cross-sectional cohort study, 1024 survivors five or more years after diagnosis, aged 18 or more years at study, treated between 1963-2001 with nephrectomy, abdominal radiotherapy, total body irradiation, cisplatin, carboplatin, ifosfamide, high-dose cyclophosphamide or hematopoietic stem cell transplantation participated. In addition, 500 age- and sex-matched controls from Lifelines, a prospective population-based cohort study in the Netherlands, participated. At a median age of 32.0 years (interquartile range 26.6-37.4), the glomerular filtration rate was under 60 ml/min/1.73m2 in 3.7% of survivors and in none of the controls. Ten survivors had kidney failure. Chronic kidney disease according to age-thresholds (glomerular filtration rate respectively under 75 for age under 40, under 60 for ages 40-65, and under 40 for age over 65) was 6.6% in survivors vs. 0.2% in controls. Albuminuria (albumin-to-creatinine ratio over3 mg/mmol) was found in 16.2% of survivors and 1.2% of controls. Risk factors for chronic kidney disease, based on multivariable analyses, were nephrectomy (odds ratio 3.7 (95% Confidence interval 2.1-6.4)), abdominal radiotherapy (1.8 (1.1-2.9)), ifosfamide (2.9 (1.9-4.4)) and cisplatin over 500 mg/m2 (7.2 (3.4-15.2)). For albuminuria, risk factors were total body irradiation (2.3 (1.2-4.4)), abdominal radiotherapy over 30 Gy (2.6 (1.4- 5.0)) and ifosfamide (1.6 (1.0-2.4)). Hypertension and follow-up 30 or more years increased the risk for glomerular dysfunction. Thus, lifetime monitoring of glomerular function in survivors exposed to these identified high risk factors is warranted.

BACKGROUND: Cancer-related fatigue is a debilitating late effect after treatment for childhood cancer. The prevalence of fatigue in childhood cancer survivors (CCSs) and associated factors for fatigue has varied widely in previous studies. Two important aspects of cancer-related fatigue, its severity and chronicity, are often not assessed. This study investigated the prevalence of, and risk factors for, severe chronic fatigue (CF) in a national cohort of Dutch CCSs. METHODS: In this study, 2810 CCSs (5-year survivors of all childhood malignancies diagnosed between 1963 and 2001 with a current age of 12-65 years) and 1040 sibling controls were included. CF was assessed with the Short Fatigue Questionnaire and was defined as a score ≥ 18 and persistence of fatigue for ≥6 months. Cancer- and treatment-related characteristics, current health problems, and demographic and lifestyle variables were assessed as potential risk factors for CF via multivariable logistic regression analyses. RESULTS: In adult CCSs and sibling controls (≥18 years old), the prevalence of CF was 26.1% and 14.1%, respectively (P < .001). In adolescent CCSs and sibling controls (<18 years old), the prevalence of CF was 10.9% and 3.2%, respectively. Female gender (odds ratio [OR], 2.13; 95% confidence interval [CI], 1.73-2.62), unemployment (OR, 2.18; 95% CI, 1.67-2.85), having 1 or more health problems (OR for 1-2, 1.48; 95% CI, 1.18-1.87; OR for >2, 2.20; 95% CI, 1.50-3.21), and a central nervous system diagnosis (OR, 1.74; 95% CI, 1.17-2.60) were significantly associated with CF in adult CCSs. CONCLUSIONS: This study shows that CCSs, regardless of their cancer diagnosis, report CF more often than sibling controls. This study provides new evidence for the prevalence of fatigue in CCSs.

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.

OBJECTIVE: Hematopoietic stem cell transplantation (HSCT) can be a curative treatment for malignant and nonmalignant diseases in children but is associated with significant late effects including growth failure. Growth hormone treatment (GHRx) is offered to improve growth, but limited data are available on its effect on adult height (AH). We aim to evaluate the effectiveness of GHRx. DESIGN: Single-center retrospective study. PATIENTS: Thirty-four patients who had received GHRx for ≥1 year were matched with two controls each, without GHRx, based on sex, indication for HSCT (malignancy, benign haematological disease or immunodeficiency), age at HSCT and conditioning with/without total body irradiation (TBI). All had reached AH. MEASUREMENTS: The primary outcome measure was the difference between AH and predicted AH (PAH) at start of GHRx or the equivalent age in controls (AH-PAH), calculated according to Bailey and Pinneau. RESULTS: GHRx was started at age 12.0 ± 2.6 years; median treatment duration was 3.8 years (range 1.7-9.2). AH-PAH standard deviation score (SDS) was significantly higher in growth hormone (GH) treated boys (-0.5 ± 0.7 SDS) than in controls (-1.5 ± 1.0 SDS, p < .001). Girls also had a higher AH-PAH after GHRx (+0.5 ± 0.6 SDS) compared to controls (-0.2 SDS ±0.7, p < .01). AH remained approximately 2 SDS below target height (TH) in treated and untreated individuals. Among GH-treated children, AH-PAH was higher in those who had received busulfan-based compared to TBI-based conditioning. CONCLUSION: GHRx had a significant positive effect on AH compared to PAH, although AH remained far below TH. Higher AH-PAH was observed in girls and in those conditioned without TBI.

This multi-center cohort-study examined late mortality among 6,165 Dutch five-year childhood cancer survivors diagnosed 1963-2001. Clinical details and cause of death were based on medical records. Mortality was 12-fold that of the general population, with 51.3 additional deaths per 10,000 person-years (21.9 yrs median follow-up). Cumulative mortality 15 yrs post-diagnosis was 6.9%, predominantly from late recurrences; thereafter the absolute contribution of other health outcomes increased. Cumulative all-cause and recurrence-related mortality were highest for Central Nervous System and bone tumor survivors. All-cause, but not subsequent tumor and circulatory disease-related cumulative mortality, was highest for patients diagnosed 1963-1979 vs. later (p-trend <0.001).

PURPOSE: The study aimed to compare the psychosocial development of young adult survivors of childhood cancer (YACCS) with a norm group of young adults from the general population. METHODS: From 2017 to 2020, 558 YACCS (18-30 years, 51% female, 10.9% CNS cancer) who participated in the Dutch Childhood Cancer Survivor Study (DCCSS) LATER cohort (diagnosed 1963-2001) part 2 completed the Course of Life Questionnaire (CoLQ), assessing the achievement of milestones. Items were grouped into the scales autonomy, psychosexual, and social development. Differences between YACCS and norm group were examined with ANOVA and Cohen's d (CoLQ scales) and with logistic regression analysis and odds ratio (OR) (CoLQ items), for the total group and YACCS of CNS cancer. RESULTS: The total group of YACCS did not report a less favorable psychosocial development than the norm group. YACCS of CNS cancer scored lower than the norm group (p < 0.001) on the scales autonomy (d = - 0.36) and psychosexual (d = - 0.46). Additionally, on half of the items of autonomy (0.25 ≤ OR ≤ 0.34), psychosexual (0.30 ≤ OR ≤ 0.48), and social (0.23 ≤ OR ≤ 0.47) development, YACCS of CNS cancer were less likely (p < 0.01) than the norm group to have achieved the milestones. CONCLUSION: Overall, psychosocial development of YACCS was as favorable as the norm, but YACCS of CNS cancer were at risk of an unfavorable psychosocial development in all domains. Monitoring psychosocial development should be included in the standards of psychosocial care, especially for CNS cancer patients and survivors, to be able to trace delay. Personalized interventions should be offered to improve the psychosocial development in an early stage.
