The value of using patient-reported outcomes for health screening during long-term follow-up after paediatric stem cell transplantation for nonmalignant diseases

Introduction: The assessment of using patient-reported outcomes (PROs) within comprehensive care follow-up programmes, specifically focused on health screening, remains largely unexplored. PROs were implemented in our late effects and comprehensive care programme after paediatric hematopoietic stem cell transplantation (HSCT) for nonmalignant diseases. The programme focuses solely on screening of physical and mental health and on discussing PROs during the consultation. Methods: The primary method of this study was semistructured interviews to explore the perspective of both patients and healthcare providers' (HCP) on the use of PROs, which were thematically analyzed. Additionally, an explorative quantitative approach with patient-reported experience measures (PREMS) was used, with a pretest–posttest design, to assess whether the use of PROs was accompanied by more patient-centred care. Results: From the patient-interviews (N = 15) four themes were extracted: use of PROs (1) help to discuss topics; (2) make the patients feel understood; (3) create a moment of self-reflection; and (4) make consultations more efficient. Pre- and postimplementation analysis of PREMs (N = 40) did not show significant differences in terms of patient-centeredness. Conclusion: Our results demonstrate the added value of integrating PROs for health screening purposes within the long-term follow-up programme after paediatric HSCT, as perceived by both patient and HCP. With the active use of PROs, patients are stimulated to consciously assess their health status. Patient Contribution: This study included patients as participants. Caregivers were approached if patients were below a certain age. Additionally, preliminary results were shared with all patients (including nonparticipants) during a patient conference day.</p

Psychosexual development, sexual functioning and sexual satisfaction in long-term childhood cancer survivors:DCCSS-LATER 2 sexuality substudy

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.</p

Psychosocial outcomes in long-term Dutch adult survivors of childhood cancer:The DCCSS-LATER 2 psycho-oncology study

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 &lt;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 &lt;.05). Risk factors for worse psychosocial outcomes were assessed with regression analyses (p &lt;.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.</p

Increased health-related quality of life impairments of male and female survivors of childhood cancer:DCCSS LATER 2 psycho-oncology study

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 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

Clinical characteristics and survival patterns of subsequent sarcoma, breast cancer, and melanoma after childhood cancer in the DCOG-LATER cohort

PURPOSE: Childhood cancer survivors are at increased risk of developing subsequent malignant neoplasms (SMNs). We compared survival and clinical characteristics of survivors with SMNs (sarcoma, breast cancer, or melanoma) and a population-based sample of similar first malignant neoplasm (FMN) patients.METHODS: We assembled three case series of solid SMNs observed in a cohort of 5-year Dutch childhood cancer survivors diagnosed 1963-2001 and followed until 2014: sarcoma (n = 45), female breast cancer (n = 41), and melanoma (n = 17). Each SMN patient was sex-, age-, and calendar year-matched to 10 FMN patients in the population-based Netherlands Cancer Registry. We compared clinical and histopathological characteristics by Fisher's exact tests and survival by multivariable Cox regression and competing risk regression analyses.RESULTS: Among sarcoma-SMN patients, overall survival [hazard ratio (HR) 1.88, 95% confidence interval (CI) 1.23-2.87] and sarcoma-specific mortality (HR 1.91, 95% CI 1.16-3.13) were significantly worse compared to sarcoma-FMN patients (foremost for soft-tissue sarcoma), with 15-year survival rates of 30.8% and 61.6%, respectively. Overall survival did not significantly differ for breast-SMN versus breast-FMN patients (HR 1.14, 95% CI 0.54-2.37), nor for melanoma-SMN versus melanoma-FMN patients (HR 0.71, 95% CI 0.10-5.00). No significant differences in tumor characteristics were observed between breast-SMN and breast-FMN patients. Breast-SMN patients were treated more often with mastectomy without radiotherapy/chemotherapy compared to breast-FMN patients (17.1% vs. 5.6%).CONCLUSIONS: Survival of sarcoma-SMN patients is worse than sarcoma-FMN patients. Although survival and tumor characteristics appear similar for breast-SMN and breast-FMN patients, treatment differs; breast-SMN patients less often receive breast-conserving therapy. Larger studies are necessary to substantiate these exploratory findings.</p

The Dutch Childhood Cancer Survivor Study (DCCSS)-LATER 2 kidney analysis examined long-term glomerular dysfunction in childhood cancer survivors

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.</p

Assessing fatigue in childhood cancer survivors:Psychometric properties of the Checklist Individual Strength and the Short Fatigue Questionnaire––a DCCSS LATER study

BACKGROUND: Fatigue is often reported by patients with childhood cancer both during and after cancer treatment. Several instruments to measure fatigue exist, although none are specifically validated for use in childhood cancer survivors (CCS). The aim of the current study was to present norm values and psychometric properties of the Checklist Individual Strength (CIS) and Short Fatigue Questionnaire (SFQ) in a nationwide cohort of CCS. METHODS: In total, 2073 participants were included from the Dutch Childhood Cancer Survivor Study (DCCSS) LATER cohort. Normative data, construct validity, structural validity, and internal consistency were calculated for the CIS and SFQ. In addition, reliability and a cutoff score to indicate severe fatigue were determined for the SFQ. RESULTS: Correlations between CIS/SFQ and vitality measures asking about fatigue were high (>0.8). Correlations between CIS/SFQ and measures of different constructs (sleep, depressive emotions, and role functioning emotional) were moderate (0.4–0.6). Confirmatory factor analysis resulted in a four‐factor solution for the CIS and a one‐factor solution for the SFQ with Cronbach's alpha for each (sub)scale showing good to excellent values (>0.8). Test–retest reliability of the SFQ was adequate (Pearson's correlation = 0.88; ICC = 0.946; weighted Cohen's kappa item scores ranged 0.31–0.50) and a cut‐off score of 18 showed good sensitivity and specificity scores (92.6% and 91.3%, respectively). CONCLUSION: The current study shows that the SFQ is a good instrument to screen for severe fatigue in CCS. The CIS can be used as a tool to assess the multiple fatigue dimensions in CCS

Self-reported outcomes on oral health and oral health-related quality of life in long-term childhood cancer survivors—A DCCSS-LATER 2 Study

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&lt;0.0005) and dental problems (r =.392, p &lt;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.</p

Psychosocial functioning of adult siblings of Dutch very long-term survivors of childhood cancer:DCCSS-LATER 2 psycho-oncology study

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 &lt;18 years old, between 1963 and 2001, &gt;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 &lt; 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 &lt; 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.</p

Hypertension in long-term childhood cancer survivors after treatment with potentially nephrotoxic therapy; DCCSS-LATER 2:Renal study

Purpose: To evaluate the prevalence of and risk factors for hypertension in childhood cancer survivors (CCSs) who were treated with potentially nephrotoxic therapies. Methods: In the Dutch Childhood Cancer Survivor Study LATER cohort part 2 renal study, 1024 CCS ≥5 years after diagnosis, aged ≥18 years at study participation, treated between 1963 and 2001 with nephrectomy, abdominal radiotherapy, total body irradiation (TBI), cisplatin, carboplatin, ifosfamide, high-dose cyclophosphamide (≥1 g/m2 per single dose or ≥10 g/m2 total) or haematopoietic stem cell transplantation participated and 500 controls from Lifelines. Hypertension was defined as blood pressure (BP) (mmHg) systolic ≥140 and/or diastolic ≥90 or receiving medication for diagnosed hypertension. At the study visit, the CKD-EPI 2012 equation including creatinine and cystatin C was used to estimate the glomerular filtration rate (GFR). Multivariable regression analyses were used. For ambulatory BP monitoring (ABPM), hypertension was defined as BP daytime: systolic ≥135 and/or diastolic ≥85, night time: systolic ≥120 and/or diastolic ≥70, 24-h: systolic ≥130 and/or diastolic ≥80. Outcomes were masked hypertension (MH), white coat hypertension and abnormal nocturnal dipping (aND). Results: Median age at cancer diagnosis was 4.7 years (interquartile range, IQR 2.4–9.2), at study 32.5 years (IQR 27.7–38.0) and follow-up 25.5 years (IQR 21.4–30.3). The prevalence of hypertension was comparable in CCS (16.3%) and controls (18.2%). In 12% of CCS and 17.8% of controls, hypertension was undiagnosed. A decreased GFR (<60 ml/min/1.73 m2) was associated with hypertension in CCS (OR 3.4, 95% CI 1.4–8.5). Risk factors were abdominal radiotherapy ≥20 Gy and TBI. The ABPM-pilot study (n = 77) showed 7.8% MH, 2.6% white coat hypertension and 20.8% aND. Conclusion: The prevalence of hypertension was comparable among CCS who were treated with potentially nephrotoxic therapies compared to controls, some of which were undiagnosed. Risk factors were abdominal radiotherapy ≥20 Gy and TBI. Hypertension and decreased GFR were associated with CCS. ABPM identified MH and a ND
