The impact of clinically relevant health conditions on psychosocial outcomes in survivors of childhood cancer: results of the DCCSS-LATER study.

PURPOSE: Investigate the association between presence, number and type of clinically relevant health conditions and a range of psychosocial outcomes (emotional, social, cognitive, physical) in survivors of childhood cancer (CCS). METHODS: CCS from the Dutch Childhood Cancer Survivor Study (DCCSS)-LATER cohort (diagnosed between 1963-2001, attained age ≥ 18, diagnosed < 18, ≥ 5 years since diagnosis) completed a questionnaire on health conditions (2013-2014), and questionnaires on psychosocial outcomes (2017-2020): Hospital Anxiety and Depression Scale, Short form 36, TNO-AZL Questionnaire for Adult Health-Related Quality of Life, and the Self-Rating Scale for Post-Traumatic Stress Disorder. Associations among health conditions and psychosocial outcomes were assessed with regression analysis, adjusting for attained age, sex, and time since diagnosis, and adjusting for multiple testing (p < 0.004). RESULTS: A total of 1437 CCS, mean age 36.3 years, 51.1% female, ≥ 15 years since diagnosis, completed questionnaires on health and psychosocial outcomes. CCS with a clinically relevant health condition, and those with more conditions had worse emotional, social, and physical outcomes; regression coefficients were small to moderate. CCS with gastro-intestinal conditions, endocrine, nervous systems, eye, or ear conditions, and especially those with secondary malignant neoplasms, reported worse psychosocial functioning; regression coefficients were small/moderate to large. CONCLUSION AND IMPLICATIONS: Health care professionals should be aware of the increased risk for psychosocial problems among CCS with health conditions, especially for survivors with secondary malignant neoplasms, gastro-intestinal, endocrine, nervous system, eye, and ear conditions. CCS may benefit from psychological interventions to develop coping strategies to manage health conditions and psychosocial consequences of the cancer trajectory.

Monitoring health related quality of life in survivorship care of young adult survivors of childhood cancer using web-based patient-reported outcome measures: survivors' and health care practitioners' perspectives on the KLIK method.

PURPOSE: The KLIK method is a tool to systematically monitor and discuss Health Related Quality of Life (HRQOL) in clinical practice. It has been successfully used in clinical practice in The Netherlands, and has recently been implemented in survivorship care for young adult childhood cancer survivors (CCSs). This study evaluates implementation fidelity and satisfaction of CCSs and healthcare practitioners (HCPs) with the KLIK method in survivorship care. METHODS: CCSs' HRQOL was monitored using the KLIK questionnaire (PedsQL generic 18-30 years). In a mixed-methods design, implementation fidelity was based on registrations, and user satisfaction was assessed with evaluation surveys (CCSs) and semi-structured interviews (CCSs, HCPs). Descriptive statistics and qualitative analysis methods were used. RESULTS: A total of 245 CCSs were eligible for the study. Fidelity was 79.2% (194/245) for registration in the KLIK PROM portal, 89.7% (174/194) for completed KLIK questionnaires, 74.7% (130/174) for its discussion during consultation. Of the eligible CCSs, 17.6% (43/245) completed the study evaluation survey. Five CCSs and HCPs were invited for an interview and participated. CCSs (7.7/10) and HCPs (7.5/10) were satisfied with the KLIK method. Reported facilitators included increased insight into CCSs' functioning, improved preparation before, and communication during consultation, without lengthening consultation duration. Barriers included CCSs not always completing KLIK questionnaires, incomplete content of the KLIK questionnaire, and the need for customization for CCSs with cognitive disabilities. CONCLUSION: The KLIK method is a feasible and valuable tool to systematically monitor and discuss HRQOL in survivorship care. Integration of the KLIK method within the organization is essential, with structural support in reminding CCSs to complete questionnaires.

Positive and negative survivor-specific psychosocial consequences of childhood cancer: the DCCSS-LATER 2 psycho-oncology study.

PURPOSE: Numerous studies investigated generic psychosocial outcomes in survivors of childhood cancer (CCS). The present study aimed to describe survivor-specific psychosocial consequences in CCS, and to identify socio-demographic and medical associated factors. METHODS: CCS from the Dutch Childhood Cancer Survivor Study (DCCSS)-LATER cohort (diagnosed 1963-2001) part 2 (age ≥ 18 years, diagnosed < 18 years, ≥ 5 years since diagnosis) completed the Benefit & Burden Scale (BBSC) and the Impact of Cancer-Childhood Cancer (IOC-CS). Items were scored on a 5-point Likert scale (range 1-5). We examined outcomes with descriptive statistics, and socio-demographic and medical associated factors with regression analyses, corrected for multiple testing (p < 0.004). RESULTS: CCS, N = 1713, age mean (M) 36 years, 49% female, ≥ 15 years since diagnosis, participated. On average, CCS reported 'somewhat' Benefit (M = 2.9), and 'not at all' to 'a little' Burden (M = 1.5) of childhood cancer. Average scores on IOC-CS' positive impact scales ranged from 2.5 (Personal Growth) to 4.1 (Socializing), and on the negative impact scales from 1.4 (Financial Problems) to 2.4 (Thinking/Memory). Apart from cognitive problems, CCS reported challenges as worries about relationship status, fertility, and how cancer had affected siblings. Female sex was associated with more Personal Growth, and more negative impact. CCS more highly educated, partnered, and employed had higher positive and lower negative impact. CCS older at diagnosis reported more positive impact. CNS tumor survivors and those who had head/cranium radiotherapy had higher negative impact. CNS tumor survivors reported less positive impact. CONCLUSION AND IMPLICATIONS: The majority of CCS reported positive impact of cancer while most CCS reported little negative impact. While this may indicate resiliency in most CCS, health care providers should be aware that they can also experience survivor-specific challenges that warrant monitoring/screening, information provision and psychosocial support.

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 <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.

Psychosocial functioning of parents of Dutch long-term survivors of childhood cancer.

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.

Psychosocial developmental milestones of young adult survivors of childhood cancer.

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.

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 < 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.

Therapist behaviours in a web-based mindfulness-based cognitive therapy (eMBCT) for chronic cancer-related fatigue - Analyses of e-mail correspondence.

Web-based mindfulness-based cognitive therapy (eMBCT) has been found effective in decreasing fatigue severity in patients suffering from Chronic Cancer-Related Fatigue (CCRF). In web-based therapy, guidance from a therapist positively affects treatment outcome. So far, less is known about what kind of therapist behaviours contribute to treatment outcome. The present study aimed at 1) identifying therapist behaviours during eMBCT and 2) exploring whether these behaviours were correlated to a decrease in fatigue severity among patients. Qualitative content analyses were performed on 537 feedback e-mails from five therapists sent to 31 patients within a secured portal. Through content analyses, nine therapist behaviours were identified: emphatic utterances, probing self-reflection, informing, psychoeducation, task prompting, paraphrasing, task reinforcement, providing group context and alliance bolstering. Among these behaviours task prompting (19%), paraphrasing (16%) and task reinforcement (15%) were the most common. Linear regression analyses showed a significant association between informing and task prompting on the one hand and a decrease in fatigue severity on the other. Multivariate analysis indicated that informing and task prompting jointly explain the decrease in fatigue. These findings underline the importance for therapists to provide patients with sufficient information and to encourage them to do the exercises.

A physiology-based model describing heterogeneity in glucose metabolism: the core of the Eindhoven Diabetes Education Simulator (E-DES).

Current diabetes education methods are costly, time-consuming, and do not actively engage the patient. Here, we describe the development and verification of the physiological model for healthy subjects that forms the basis of the Eindhoven Diabetes Education Simulator (E-DES). E-DES shall provide diabetes patients with an individualized virtual practice environment incorporating the main factors that influence glycemic control: food, exercise, and medication. The physiological model consists of 4 compartments for which the inflow and outflow of glucose and insulin are calculated using 6 nonlinear coupled differential equations and 14 parameters. These parameters are estimated on 12 sets of oral glucose tolerance test (OGTT) data (226 healthy subjects) obtained from literature. The resulting parameter set is verified on 8 separate literature OGTT data sets (229 subjects). The model is considered verified if 95% of the glucose data points lie within an acceptance range of ±20% of the corresponding model value. All glucose data points of the verification data sets lie within the predefined acceptance range. Physiological processes represented in the model include insulin resistance and ß-cell function. Adjusting the corresponding parameters allows to describe heterogeneity in the data and shows the capabilities of this model for individualization. We have verified the physiological model of the E-DES for healthy subjects. Heterogeneity of the data has successfully been modeled by adjusting the 4 parameters describing insulin resistance and ß-cell function. Our model will form the basis of a simulator providing individualized education on glucose control.
