Quality of life in survivors of childhood cancer: a systematic review of the literature (2001-2008)

Physical Activity, Fitness, and Health-Related Quality of Life in Children and Adolescent Cancer Survivors: A Cross-Sectional Study (iBoneFIT Project)

Background/Objectives: This study aims to evaluate the health-related quality of life (HRQoL) of children and adolescent cancer survivors in relation to previously published normative values for typically developing children and adolescents, as well as to analyze the differences in HRQoL based on their levels of physical activity and fitness. Methods: Cross-sectional study with 116 cancer survivors (12.1 ± 3.3 years, 57.8% boys) from two pediatric oncology units in Andalusia (Spain). HRQoL was assessed using PedsQL 4.0 Generic Core Scales. Physical activity was measured with accelerometers, and fitness was evaluated using self-reported and objective tests for muscular fitness. Independent samples t-tests to compare HRQoL between our sample and the normative values published for typically developing children and adolescents of the same age and analysis of covariance (ANCOVA) were conducted to assess differences in HRQoL according to physical activity and fitness categories in our sample. Results: Children and adolescent cancer survivors had lower HRQoL scores compared to typically developing children's and adolescents' normative values, except for social functioning. Higher levels of moderate-to-vigorous physical activity were associated with better total, physical, and psychosocial HRQoL scores. Children and adolescent cancer survivors with better levels of cardiorespiratory fitness, motor fitness, and flexibility reported better HRQoL scores in total and psychosocial domains. However, muscular fitness (self-reported and objectively measured) did not show a significant difference in HRQoL. Conclusions: Children and adolescent cancer survivors experience lower HRQoL than their typically developing counterparts. Engaging in at least 30 min of moderate-to-vigorous physical activity per day is associated with fewer HRQoL impairments. Improved fitness, particularly cardiorespiratory fitness, motor fitness, and flexibility, are associated with better HRQoL outcomes. These findings highlight the association between physical activity, fitness levels, and HRQoL in children and adolescent cancer survivors, suggesting the potential benefits of promoting physical activity and enhancing fitness levels.

Sarcoma Assessment Measure-Paediatric Version (SAM-Paeds): development of a disease-specific patient reported outcome measure for children with sarcoma

PURPOSE

Sarcomas account for approximately 10-15% of all cancer in children aged ≤ 16. Poorer health-related quality of life (HRQoL) is recorded in comparison to other cancers; however, these studies are limited by generic HRQoL measures not being specific to patients with sarcoma. The aim of this study was to develop paediatric version of the Sarcoma Assessment Measure (SAM).

METHODS

This mixed methods study comprised three stages: item generation, item reduction and establishing content validity. Children aged 8-16 years and parents of children aged 0-16 years with a diagnosis of sarcoma and within 5 years of completion of treatment were invited to participate.

RESULTS

A total of 29 children and 38 parents from three sites participated in the study. Content analysis of the interview transcripts identified 277 post-diagnosis experience statements of which 128 'items' were included in an Item Reduction Questionnaire, grouped into six domains; physical, disability and inclusion; impact of diagnosis; emotional, impact on family, education. Items with a mean score < 5 and a content validity index of < 0.75 were removed. The final version of SAM-Paeds comprises 33 items (parent version) and 21 items (child version).

CONCLUSION

This study has developed the first disease-specific HRQoL measure for paediatric sarcoma patients. SAM-Paeds is planned for inclusion within international sarcoma clinical trials and will be validated alongside current generic measures. Developed with the same methodology as the adult SAM questionnaire will facilitate the assessment of QoL longitudinally to assess the long-term impact of the diagnosis and treatment of sarcoma in childhood.

Mapping and comparing the quality of life outcomes in childhood and adolescent and young adult cancer survivors: an umbrella review and future directions

BACKGROUND

A cancer diagnosis early in life can leave a legacy in terms of compromised Quality of Life (QoL). There is a lack of clarity regarding the impact on QoL according to age at diagnosis, with childhood cancer survivors (CCS) and adolescents and young adult cancer survivors (AYACS) often combined. As part of an EORTC Quality of Life Group study, this umbrella review aims to (1) identify the QoL outcomes reported in the literature for both CCS and AYACS, and (2) investigate the similarities and differences in QoL challenges between both groups.

METHODS

A systematic literature search of systematic reviews and meta-analyses was conducted in December 2023 using PubMed, PsychInfo, and CINAHL. Methodological quality was evaluated using the AMSTAR tool.

RESULTS

Overall, 1457 articles were assessed, and 39 systematic reviews and meta-analyses met the inclusion criteria. QoL outcomes were categorized into eight QoL domains, all of which were reported in both groups of young survivors. However, reviews on CCS often focused on outcomes relating to emotional functioning, cognitive difficulties, social challenges, school functioning, body image and overall happiness, whereas AYACS reviews had a greater focus on depressive symptoms, outcomes related to sexual health and reproductive health, employment, financial difficulties, self-image and identity and the impact of cancer.

CONCLUSION

This umbrella review comprehensively explores QoL outcomes among CCS and AYACS, revealing both shared and distinct challenges. Future research should focus on developing tailored questionnaires, emphasizing transition periods and incorporating a life perspective to capture unique developmental tasks of young survivors.

Health-Related Quality of Life of Adolescent and Young Adult-Aged Childhood Cancer Survivors in a South African Cohort: A Pilot Study Using the Minneapolis-Manchester Quality of Life Instrument

Purpose: We investigated the health-related quality of life (HRQoL) of an adolescent and young adult (AYA)-aged South African childhood cancer survivor (CCS) cohort. Methods: Participants completed the Minneapolis-Manchester Quality of Life adolescent and adult forms. The overall Cronbach's alpha coefficients were 0.81 (adolescent form) and 0.92 (adult form). The scale-level content validity indexes were acceptable (0.88 and 0.89 for the adolescent and adult forms, respectively). The total domain and overall HRQoL scores were calculated. Results: Sixty-two survivors completed the adolescent form and 30 completed the adult form. The median age was 17.5 years (range 13-34 years), and the median time from diagnosis was 12 years (male:female ratio 1:1.2). Risk factors for poor physical functioning included age at study visit (p = 0.015), solid tumor diagnosis (p = 0.012), radiotherapy (p = 0.021), and surgery (p = 0.006). Six or more late effects impacted most domains negatively; severe late effects (p = 0.020) decreased physical functioning. Lower socioeconomic status was associated with poorer physical (p = 0.006) and cognitive (p = 0.047) functioning. The adult form cohort had poorer psychological (p = 0.014) and social functioning (p = 0.005) and body image (p = 0.016) than the adolescent form cohort. Conclusion: Older age, radiotherapy, surgery, solid tumor diagnosis, and the number and severity of late effects negatively influenced HRQoL in AYA-aged CCSs. A long-term follow-up (LTFU) risk stratification system should include HRQoL status to assist with holistic LTFU care.

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.

Parent-reported health-related quality of life in pediatric childhood cancer survivors and factors associated with poor health-related quality of life in aftercare

PURPOSE

Despite advances in cancer treatment, there is a prevalence of pediatric childhood cancer survivors still at risk of developing adverse disease and treatment outcomes, even after the end of treatment. The present study aimed to (1) explore how mothers and fathers assess the health-related quality of life (HRQoL) of their surviving child and (2) evaluate risk factors for poor parent-reported HRQoL in childhood cancer survivors about 2.5 years after diagnosis.

METHODS

We assessed parent-reported HRQoL of 305 child and adolescent survivors < 18 years diagnosed with leukemia or tumors of central nervous system (CNS) with the KINDL-R questionnaire in a prospective observational study with a longitudinal mixed-methods design.

RESULTS

In agreement with our hypotheses, our results show that fathers rate their children's HRQoL total score as well as the condition-specific domains family (p = .013, d = 0.3), friends (p = .027, d = 0.27), and disease (p = .035, d = 0.26) higher than mothers about 2.5 years after diagnosis. Taking variance of inter-individual differences due to family affiliation into account, the mixed model regression revealed significant associations between the diagnosis of CNS tumors (p = .018, 95% CI [- 7.78, - 0.75]), an older age at diagnosis, (p = .011, 95% CI [- 0.96, - 0.12]), and non-participation in rehabilitation (p = .013, 95% CI [- 10.85, - 1.28]) with poor HRQoL in children more than 2 years after being diagnosed with cancer.

CONCLUSION

Based on the results, it is necessary for health care professionals to consider the differences in parental perceptions regarding children's aftercare after surviving childhood cancer. High risk patients for poor HRQoL should be detected early, and families should be offered support post-cancer diagnosis to protect survivors' HRQoL during aftercare. Further research should focus on characteristics of pediatric childhood cancer survivors and families with low participation in rehabilitation programs.

Health Competence Beliefs and Health-Related Quality of Life Among Adolescent and Young Adult Survivors of Childhood Cancer and Healthy Peers

Purpose: Adolescent and young adult (AYA) survivors of childhood cancer are at risk for late-effects that can impact how one perceives their health and well-being. Understanding beliefs about health competence and well-being among survivors can help identify support needs and increase adherence to long-term follow-up guidelines. This study examined differences in health competence beliefs and health-related quality of life (HRQOL) between AYA survivors of childhood cancer and matched healthy peers. In addition, the relationship between health competence beliefs and HRQOL, as well as the moderating effect of cancer survivorship, was investigated. Methods: Survivors (n = 49) and healthy peers (n = 54) completed measures about health competence beliefs (i.e., Health Perception, Cognitive Competence, Autonomy, and School/Work Functioning) and HRQOL. Multiple group analysis was used to investigate differences in health competence beliefs and HRQOL between survivors and peers. Multivariate multiple regression analyses were used to investigate the relationships between health competence beliefs and HRQOL. Finally, a history of cancer was examined as a possible moderator using additional multivariate multiple regression analyses. Results: Survivors reported significantly lower Health Perception, Cognitive Competence, Autonomy, and School/Work Functioning scores compared to healthy peers. Among both groups, Health Perception and Cognitive Competence scores were associated with multiple domains of HRQOL. These relationships were not moderated by having a history of cancer. Conclusions: Perceptions about one's health and cognitive abilities may impact HRQOL among AYA survivors of childhood cancer and health peers. Identifying those at risk for poor well-being may help to guide interventions aimed at increasing adherence to medical recommendations.

A joint international consensus statement for measuring quality of survival for patients with childhood cancer

The aim of treating childhood cancer remains to cure all. As survival rates improve, long-term health outcomes increasingly define quality of care. The International Childhood Cancer Outcome Project developed a set of core outcomes for most types of childhood cancers involving relevant international stakeholders (survivors; pediatric oncologists; other medical, nursing or paramedical care providers; and psychosocial or neurocognitive care providers) to allow outcome-based evaluation of childhood cancer care. A survey among healthcare providers (n = 87) and online focus groups of survivors (n = 22) resulted in unique candidate outcome lists for 17 types of childhood cancer (five hematological malignancies, four central nervous system tumors and eight solid tumors). In a two-round Delphi survey, 435 healthcare providers from 68 institutions internationally (response rates for round 1, 70-97%; round 2, 65-92%) contributed to the selection of four to eight physical core outcomes (for example, heart failure, subfertility and subsequent neoplasms) and three aspects of quality of life (physical, psychosocial and neurocognitive) per pediatric cancer subtype. Measurement instruments for the core outcomes consist of medical record abstraction, questionnaires and linkage with existing registries. This International Childhood Cancer Core Outcome Set represents outcomes of value to patients, survivors and healthcare providers and can be used to measure institutional progress and benchmark against peers.

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<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.

Thyroid hormone triiodothyronine does not protect ovarian reserve from DNA damage induced by X-ray and cisplatin

PURPOSE

Cancer therapy can induce premature ovarian insufficiency, necessitating methods for preserving fertility in female cancer patients. However, the only accepted clinical practice for doing so is cryopreservation of embryos, unfertilized ova, and ovarian tissue, despite potential options such as in vitro maturation of follicles. Therefore, considerable interest has arisen in fertoprotective agents, with research on rat ovarian granulosa cells suggesting that triiodothyronine (T3) regulates an anti-apoptosis mechanism that protects the ovarian reserve from paclitaxel-induced DNA damage. In this study, we used postnatal day 5 mouse ovary to confirm the existence of T3 thyroid hormone receptor (THR), as well as to investigate the potential protective effects of T3 against cisplatin- and X-ray-induced apoptosis. We also tested the potential anti-apoptotic effect of T3 in the breast cancer cell line MDA-MB-231.

METHODS

We treated cultured mouse ovaries with varying concentration of T3 and 4 μM cisplatin and 0.2 Gy X-ray. Real-time PCR, histological analysis, immunoblot analysis, and immunofluorescence were performed to assess the potential anti-apoptotic effects of T3.

RESULTS

We confirmed that THR alpha and beta are expressed in the mouse ovary. T3 (0.1, 1, 10, 100 nM, and 1 µM) does not protect ovarian reserve from cisplatin- or X-ray-induced apoptosis or DNA damage. Similarly, it does not protect mouse granulosa cells and MDA-MB-231 cells from cisplatin- or X-ray-induced apoptosis.

CONCLUSION

Our findings suggest that T3 is ineffective as a fertoprotective agent, and its candidacy as a potential agent to preserve fertility should be reconsidered.

Ten Considerations for Integrating Patient-Reported Outcomes into Clinical Care for Childhood Cancer Survivors

Patient-reported outcome measures (PROMs) are subjective assessments of health status or health-related quality of life. In childhood cancer survivors, PROMs can be used to evaluate the adverse effects of cancer treatment and guide cancer survivorship care. However, there are barriers to integrating PROMs into clinical practice, such as constraints in clinical validity, meaningful interpretation, and technology-enabled administration of the measures. This article discusses these barriers and proposes 10 important considerations for appropriate PROM integration into clinical care for choosing the right measure (considering the purpose of using a PROM, health profile vs. health preference approaches, measurement properties), ensuring survivors complete the PROMs (data collection method, data collection frequency, survivor capacity, self- vs. proxy reports), interpreting the results (scoring methods, clinical meaning and interpretability), and selecting a strategy for clinical response (integration into the clinical workflow). An example framework for integrating novel patient-reported outcome (PRO) data collection into the clinical workflow for childhood cancer survivorship care is also discussed. As we continuously improve the clinical validity of PROMs and address implementation barriers, routine PRO assessment and monitoring in pediatric cancer survivorship offer opportunities to facilitate clinical decision making and improve the quality of survivorship care.

Patient Reported Outcomes and Measures in Children with Rhabdomyosarcoma

In addition to optimising survival of children with rhabdomyosarcoma (RMS), more attention is now focused on improving their quality of life (QOL) and reducing symptoms during treatment, palliative care or into long-term survivorship. QOL and ongoing symptoms related to the disease and its treatment are outcomes that should ideally be patient-reported (patient-reported outcomes, PROs) and can be assessed using patient-reported outcome measures (PROMS). This commentary aims to encourage PRO and PROM use in RMS by informing professionals in the field of available PROMs for utilisation in paediatric RMS and provide considerations for future use in research and clinical practice. Despite the importance of using PROMs in research and practice, PROMs have been reported scarcely in paediatric RMS literature so far. Available literature suggests lower QOL of children with RMS compared to general populations and occurrence of disease-specific symptoms, but a lack of an RMS-specific PROM. Ongoing developments in the field include the development of PROMs targeted at children with RMS specifically and expansion of PROM evaluation within clinical trials.

Survivorship, Quality of Life, and Transition to Adult Care for Pediatric and Adolescent Thyroid Cancer Survivors

The importance of long-term survivorship care to reduce survivor and family anxiety and burden, decrease emergency visits and health care costs, improve knowledge, as well as implement timely surveillance is widely accepted. Most childhood cancer survivors suffer from an increased number of medical and psychosocial comorbidities as they age and are at a higher risk for early mortality, which differs by cancer diagnosis. Childhood thyroid cancer survivors fall within this spectrum. Some have significant complications and/or late effects from treatment, whereas others have no long-term medical late effects, but almost all will require life-long thyroid hormone replacement therapy. Therefore, providing survivorship and transitional care, including a survivorship and/or transitional care plan (SCP/TCP), as well as periodically assessing the needs and quality of life for the patient and their family, should be implemented for our young thyroid cancer survivors.

A Review of Patient-Reported Outcome Measures in Childhood Cancer

Patient-reported outcomes (PROs) are used in clinical work and research to capture the subjective experiences of childhood cancer patients and survivors. PROs encompass content domains relevant and important to this population, including health-related quality-of-life (HRQOL), symptoms, and functional status. To inform future efforts in the application of PRO measures, this review describes the existing generic and cancer-specific PRO measures for pediatric cancer populations and summarizes their characteristics, available language translations, content coverage, and measurement properties into tables for clinicians and researchers to reference before choosing a PRO measure that suits their purpose. We have identified often unreported measurement properties that could provide evidence about the clinical utility of the PRO measures. Routine PRO assessment in pediatric cancer care offers opportunities to facilitate clinical decision-making and improve quality of care for these patients. However, we suggest that before implementing PRO measures into research or clinical care, the psychometric properties and content coverage of the PRO measures must be considered to ensure that PRO measures are appropriately assessing the intended construct in childhood cancer patients.

Predominant approaches in studies on health-related quality of life of young survivors of childhood or adolescent cancer: an integrative literature review

Abstract Survivors of childhood cancer constitute a growing population. The disease experienced, its treatment or the occurrence of late complications may affect survivors’ health-related quality of life (HRQOL). Understanding HRQOL is a challenge due to its conceptual complexity and the mode in which it is studied. Objective: To identify the predominant lines of research in the study of HRQOL in this population. Methods: An integrative literature review was carried out, involving a systematic search of primary articles indexed in the Scopus and PubMed databases. Results: In the 48 publications selected, four main lines of research were identified: HRQOL in survivors in general; HRQOL in long-term survivors; the study of determinants of HRQOL; and the study of methodological aspects of HRQOL measurement. A quantitative approach using generic measurement instruments predominates, and the conceptual model of HRQOL based on function emphasizes the importance of physical, psychological, and social functionality and the impact of the disease and treatment on these aspects. Conclusions: incorporating a qualitative, meaning-based approach to the understanding of lived experiences from a subjective and holistic perspective is indispensable.

Development and Validation of Models to Predict Poor Health-Related Quality of Life Among Adult Survivors of Childhood Cancer

IMPORTANCE

Risk prediction models are important to identify survivors of childhood cancer who are at risk of experiencing poor health-related quality of life (HRQOL) as they age.

OBJECTIVE

To develop and validate prediction models for a decline in HRQOL among adult survivors of childhood cancer.

DESIGNS, SETTING, AND PARTICIPANTS

This prognostic study included 4755 adults from the Childhood Cancer Survivor Study (CCSS) diagnosed between January 5, 1970, and December 31, 1986, who completed baseline (time 0 [November 3, 1992, to August 28, 2003]) and 2 follow-up (time 1 [February 12, 2002, to May 21, 2005] and time 2 [January 6, 2014, to November 30, 2016]) surveys. Data were analyzed from June 19, 2019, to February 2, 2022.

EXPOSURES

Sociodemographic, lifestyle, and emotional factors, and chronic health conditions (CHCs) were assessed at time 0 and time 1, and neurocognitive factors were assessed at time 1 to predict HRQOL at time 2 and a decline in HRQOL between time 1 and time 2. Impaired health states were defined as CHC grades 2 to 4 using the modified Common Terminology Criteria for Adverse Events, version 4.03, and mental and neurocognitive status as 1 SD or more below reference levels.

MAIN OUTCOMES AND MEASURES

Health-related quality of life was operationalized using the Medical Outcomes Study 36-Item Short Form Health Survey Physical (PCS) and Mental (MCS) Component Summary and classified by optimal (≥40) or suboptimal (<40) at each point (main outcome). A decline in HRQOL was defined as a change from optimal to suboptimal between time 1 and time 2. Multivariable logistic regression identified factors associated with HRQOL decline. The cohort was randomly split into training (80%) and test (20%) data sets for model development and validation; the area under the receiver operating characteristic curve was used to evaluate prediction performance.

RESULTS

A total of 4755 adults (mean [SD] age at time 0, 24.3 [7.6] years; 2623 [55.2%] women) were included in the analysis. Between time 1 and time 2, 285 of 3294 survivors (8.7%) had declining PCS and 278 of 3294 (8.4%) had declining MCS. Risk factors associated with PCS decline included female sex (odds ratio [OR], 1.67 [95% CI, 1.25-2.24]), family income less than $20 000 vs $80 000 or more (OR, 2.00 [95% CI, 1.21-3.30]), presence of CHCs (OR for neurological, 2.16 [95% CI, 1.51-3.10]; OR for endocrine, 2.25 [95% CI, 1.44-3.52]; OR for gastrointestinal tract, 1.89 [95% CI, 1.32-2.69]; OR for respiratory, 1.66 [95% CI, 1.06-2.59]; OR for cardiovascular, 1.53 [95% CI, 1.14-2.06]), and depression (OR, 1.79 [95% CI, 1.20-2.67]). Risk factors associated with MCS decline included unemployment vs full-time employment (OR, 1.68; [95% CI, 1.19-2.38]), current vs never cigarette smoking (OR, 2.03 [95% CI, 1.37-3.00]), depression (OR, 4.29 [95% CI, 2.44-7.55]), somatization (OR, 1.63 [95% CI, 1.05-2.53]), impaired task efficiency (OR, 1.90 [95% CI, 1.34-2.68]), and impaired organization (OR, 1.67 [95% CI, 1.12-2.48]). The areas under the receiver operating characteristic curve for the test models were 0.74 (95% CI, 0.67-0.81) for declining PCS and 0.68 (95% CI, 0.60-0.75) for declining MCS.

CONCLUSIONS AND RELEVANCE

In this prognostic study of adult survivors of childhood cancer who experienced declining HRQOL, CHCs were associated with a decline in physical HRQOL, whereas current smoking and emotional and neurocognitive impairment were associated with a decline in mental HRQOL. These findings suggest that interventions targeting modifiable risk factors are needed to prevent poor HRQOL in this population.

The impact of CNS-directed treatment on quality of life in childhood cancer survivors

PURPOSE

Pediatric cancer survivors may have lower quality of life (QoL), but most research has assessed outcomes either in treatment or long-term survivorship. We focused on early survivorship (i.e., 3 and 5 years post-diagnosis), examining the impact of CNS-directed treatment on child QoL, as well as sex and age at diagnosis as potential moderators.

METHODS

Families of children with cancer (ages 5-17) were recruited at diagnosis or relapse (N = 336). Survivors completed the PedsQL at 3 (n = 96) and 5 years (n = 108), along with mothers (101 and 105, respectively) and fathers (45 and 53, respectively). The impact of CNS treatment, sex, and age at diagnosis on child QoL was examined over both time since diagnosis and time since last treatment using mixed model analyses.

RESULTS

Parent-report of the child's total QoL was in the normative range and stable between 3 and 5 years when examining time since diagnosis, while child reported QoL improved over time (p = 0.04). In terms of time since last treatment, mother and child both reported the child's QoL improved over time (p = 0.0002 and p = 0.0006, respectively). Based on parent-report, males with CNS-directed treatment had lower total QoL than females and males who did not receive CNS-directed treatment. Age at diagnosis did not moderate the impact of treatment type on total QoL.

CONCLUSIONS

Quality of life (QoL) in early survivorship may be low among males who received CNS-directed treatment. However, this was only evident on parent-report. Interventions to improve child QoL should focus on male survivors who received CNS-directed treatment, as well as females regardless of treatment type.

Self-efficacy, post-traumatic growth, and quality of life of pediatric cancer survivors: A cross-sectional study

PURPOSE

This study explored the relationships among self-efficacy, post-traumatic growth, and quality of life in a sample of pediatric cancer survivors and analyzed the factors associated with quality of life in pediatric cancer survivors.

METHOD

A questionnaire assessed self-efficacy, post-traumatic growth, and health-related quality of life. Data were collected from December 2017 to December 2018 at a hospital in Seoul, South Korea from 115 pediatric cancer survivors.

RESULTS

Health-related quality of life showed significant positive correlations with general self-efficacy and social self-efficacy, but did not significantly correlate with post-traumatic growth. Factors that significantly influenced health-related quality of life were current age (β = 0.24, p = .007), currently not attending school (β = -0.19, p = .029), having many uncomfortable symptoms (β = -0.26, p = .006), some daily life difficulties (β = -0.23, p = .015), general self-efficacy (β = 0.17, p = .043), and social self-efficacy (β = 0.32, p = .001). This model explained 50% of the variance in self-reported health-related quality of life.

CONCLUSION

Health-related quality of life in pediatric cancer survivors was not associated with post-traumatic growth. However, high health-related quality of life was related to being older, attending school, lacking uncomfortable symptoms and difficulties in daily life, and having high self-efficacy. Interventions may improve health-related quality of life in pediatric cancer survivors if they increase self-efficacy, reduce uncomfortable symptoms and difficulties in daily life and for children who are survivors of cancer, and encourage maintaining school life.

Health-related quality of life in Dutch adult survivors of childhood cancer: A nation-wide cohort study

AIM

To investigate the health-related quality of life (HRQOL) of Dutch adult childhood cancer survivors (CCS) and to identify risk factors of impaired HRQOL.

METHODS

Adult CCS (age >18, diagnosed <18, ≥5 years since diagnosis) from the Dutch LATER registry completed the Medical Outcome Study Short Form 36 (SF-36) to measure HRQOL and provided sociodemographic characteristics. Age-adjusted mean SF-36 scale scores of CCS were compared to the Dutch general population for men and women separately using t-tests, with effect size d. Multivariate logistic regression models were built to identify sociodemographic and cancer-related risk factors for impaired physical and mental HRQOL.

RESULTS

Both male and female CCS (N = 2301, mean age = 35.4 years, 49.6% female) reported significantly (p ≤ .005) worse HRQOL than the general population on almost all scales of the SF-36 (-.11 ≤ d ≤ -.56). Largest differences were found on vitality and general health perceptions. Significant risk factors (p ≤ .05) for impaired physical HRQOL were female sex, older age at diagnosis, not having a partner, low educational attainment, disease recurrence and exposure to radiotherapy, specifically to lower extremity radiation. Odds ratios (ORs) ranged from 1.6 to 3.7. Significant risk factors for impaired mental HRQOL were age 26-35 years, male sex, not having a partner and low educational attainment. ORs ranged from 1.3 to 2.0.

CONCLUSION

Adult CCS had worse HRQOL than the general population. CCS most at risk were those with low educational attainment and without a partner. Adult CCS could benefit from routine surveillance of their HRQOL. Special attention for CCS' vitality and health perceptions and beliefs is warranted.

Identification of Evidence for Key Positive Psychological Constructs in Pediatric and Adolescent/Young Adult Patients with Cancer: A Scoping Review

Introduction: Children and adolescents/young adults (AYAs) with cancer are a vulnerable population susceptible to numerous late effects, such as fatigue and depression, which may diminish their long-term psychological, physical, spiritual, and emotional health. A well-rounded understanding of how positive psychological constructs affect the quality of care and treatment outcomes is therefore warranted. Methods: We conducted a scoping review of 15 positive psychological constructs in children and AYAs with cancer. The primary research questions were (1) what is known about positive psychological constructs in children and AYAs with cancer; (2) what value is ascribed to these constructs by patients? Results: Two hundred seventy-six articles were included after database search and screening. These studies were mostly observational or qualitative and conducted in North America. Constructs were often poorly defined, and measurement tools used to gather data were wide ranging. Numerous factors were correlated with increased or decreased expression of certain constructs, but overall themes were difficult to identify. Similarly, patients often spoke of what increased or decreased expression of a construct, with less emphasis on what they implicitly value. Discussion: This scoping review found ample evidence for what increases or decreases expression of positive psychological constructs, but this evidence was observational and often conflicting. In the future, we recommend the development of a core set of psychological outcomes, with definitions and corresponding measurement tools. We further recommend an emphasis on randomized trials to more rigorously study how expression of constructs can be improved and what effect this has on the quality of life.

Exploring Differences in Perceived Satisfaction, Resilience, and Achievement Between Hispanic and Non-Hispanic White Childhood Cancer Survivors

INTRODUCTION

To address gaps in understanding disparities of posttraumatic growth among childhood cancer survivors, the aims of this study were to (1) compare satisfaction, resilience, and achievement among Hispanic and non-Hispanic White survivors; and (2) examine relationships between sociodemographic and clinical factors with satisfaction, resilience, and achievement.

METHOD

Survivors (N = 116) at Children's Hospital of Orange County After Cancer Treatment Survivorship Program completed the Child Health and Illness Profile-Adolescent Edition.

RESULTS

Resilience (p = .003) and achievement (p = .005) were lower among Hispanic survivors. Resilience was positively associated with satisfaction (p < .01) and achievement (p < .01) and achievement was positively associated with years of schooling (p < .01). No differences were found between Hispanic and non-Hispanic White satisfaction scores (p = .95).

DISCUSSION

Our findings suggest ethnic disparities in posttraumatic growth in childhood cancer survivors. Interventions aimed at promoting posttraumatic growth are vital to address these differences.

Psychological Outcomes, Health-Related Quality of Life, and Neurocognitive Functioning in Survivors of Childhood Cancer and Their Parents

Childhood cancer disrupts the lives of patients and their families and affects acute and long-term psychological health. This article summarizes (1) psychological challenges, including depression, anxiety, worries, and posttraumatic stress, as well as positive outcomes such as benefit finding and posttraumatic growth in young survivors and parents; (2) health-related quality of life; (3) interventions to support survivors and parents with psychological difficulties; and (4) neurocognitive problems and interventions to help alleviate them. Although many survivors and parents fare well in the long term, many survivors may benefit from interventions. Interventions should be further evaluated and integrated into routine clinical care.

Childhood Cancer Survivors: Self-Reported Quality of Life during and after the Cancer Trajectory

Objective

This cross-sectional study aimed to present how the unique cancer experience in childhood influences young adults' quality of life (QOL).

Methods

Qualitative and quantitative methods were used to code and analyze a study-specific questionnaire (133 items). These data are presented in accordance with a conceptual QOL/health-related QOL model.

Results

The participants included 34 women and 28 men (n = 62) diagnosed with solid tumors/lymphoma in the period 1983-2003, who had been treated at the same childhood cancer center in Sweden. The current mean age was 28.7 years (range: 18-45, standard deviation [SD]: 6.3, median value: 28.5), the mean age at diagnosis was 12.9 years (range: 8-17, SD: 2.3, median value: 13), and the mean time elapsed since treatment was 15.7 years (range: 4-28, SD: 2.4, median value: 15). The response rate was 65%. Higher levels of psychological maturity were reported by women versus men (P = 0.01) and by survivors diagnosed with cancer during adolescence versus school age (P = 0.04). Male participants reported lower levels of physical limitations (P = 0.03) and emotional distress when being of treatment and in contact with health care services (P = 0.04). The strongest factor influencing QOL during therapy was parental support (97%), while the strongest factors after therapy were to live a life similar to peers (82%) and to be satisfied with one's life situation (81%). During treatment, limitations influencing QOL were related to lack of school support (2%), and after treatment, to deteriorated relationships with siblings (5%).

Conclusions

Life-threatening diseases at young ages have long-term psychosocial effects with ambiguous results at multiple levels. To capture these experiences, we recommend clinical studies that are based on conceptual clarifying frameworks and adopt a quantitative and qualitative research approach.

Environment, lifestyle behavior and health-related quality of life in childhood and adolescent cancer survivors of extracranial malignancies

BACKGROUND

Childhood cancer is a chronic disease with high survival rates. Childhood cancer survivors (CCS) can still face health effects later in their lives. Health-related quality of life (HRQoL) and the factors that modify it allow CCS and their families to improve care in the long-term follow-up. This study aims to: (1) examine the differences in HRQoL between CCS of extracranial malignancies and a comparison group, and (2) explore the clinical, environmental and lifestyles factors implicated in the HRQoL of CCS.

METHODS

In this cross-sectional study with a case vs. non-case comparison, the HRQoL of 117 CCS between 8 and 18 years old was compared with healthy non-cases paired by sex and age. The Pediatric Environmental History (PEHis) was applied to obtain information on sociodemographic, clinical, environmental and lifestyle factors. The PedsQL™ Generic Core Scales questionnaire was used to evaluate HRQoL.

RESULTS

In the multivariate analysis among the CCS, the following variables were significantly associated with HRQoL: Poor outdoor air quality (Total, Psychosocial, Emotional, Social and School domains); household income (Total, Psychosocial and School domains); and the presence of late effects (Total, Physical, Psychosocial, and Social domains); regular contact with nature (Physical domain); and the daily hours of screen-time (Emotional domain). CCS present HRQoL results superior to the non-cases group in the physical domain (86.10 vs. 80.34; p=0.001), finding no differences in the other domains evaluated.

CONCLUSIONS

An environmental and community health approach, such as PEHis, in CCS long-term programs promoting the creation of healthier environments and lifestyles contributes to improving their HRQoL and secondarily other chronic diseases.

Patient-reported outcomes in paediatric cancer survivorship: a qualitative study to elicit the content from cancer survivors and caregivers

OBJECTIVES

Content elucidation for patient-reported outcomes (PROs) in paediatric cancer survivorship is understudied. We aimed to compare differences in the contents of five PRO domains that are important to paediatric cancer survivorship through semistructured interviews with paediatric cancer survivors and caregivers, and identified new concepts that were not covered in the item banks of the Patient-Reported Outcomes Measurement Information System (PROMIS).

DESIGN

Semistructured interviews to collect qualitative PRO data from survivors and caregivers.

SETTING

A survivorship care clinic of a comprehensive cancer centre in the USA.

PARTICIPANTS

The study included 51 survivors (<18 years old) and 35 caregivers who completed interviews between August and December 2016. Content experts coded the transcribed interviews into 'meaningful concepts' per PROMIS item concepts and identified new concepts per a consensus. Frequencies of meaningful concepts used by survivors and caregivers were compared by Wilcoxon rank-sum test.

RESULTS

For pain and meaning and purpose, 'Hurt a lot' and 'Purpose in life' were top concepts for survivors and caregivers, respectively. For fatigue and psychological stress, 'Needed to sleep during the day'/'Trouble doing schoolwork' and 'Felt worried' were top concepts for survivors, and 'Felt tired' and 'Felt distress'/'Felt stressed' for caregivers. Survivors reported more physically relevant contents (eg, 'Hard to do sport/exercise'; 0.78 vs 0.23, p=0.007) for pain, fatigue and stress, whereas caregivers used more emotionally relevant concepts (eg, 'Too tired to enjoy things I like to do'; 0.31 vs 0.05, p=0.025). Both groups reported positive thoughts for meaning and purpose (eg, 'Have goals for myself'). One (psychological stress, meaning and purpose) to eleven (fatigue) new concepts were generated.

CONCLUSIONS

Important PRO contents in the form of meaningful concepts raised by survivors and caregivers were different and new concepts emerged. PRO measures are warranted to include survivorship-specific items by accounting for the child's and the caregiver's viewpoints.

Neurocognitive and psychosocial outcomes in adult survivors of childhood soft-tissue sarcoma: A report from the St. Jude Lifetime Cohort

BACKGROUND

To the authors' knowledge, few studies to date have examined long-term neurocognitive outcomes in survivors of childhood soft-tissue sarcoma.

METHODS

A total of 150 survivors (41% of whom were female with a mean current age of 33 years [SD, 8.9 years] and a time since diagnosis of 24 years [SD, 8.7 years]) and 349 community controls (56% of whom were female with a mean current age of 35 years [SD, 10.2 years]) completed comprehensive neuropsychological testing, echocardiography, electrocardiography, pulmonary function tests, endocrine evaluation, and physical examination. Patient-reported outcomes of health-related quality of life (HRQOL) and social attainment were collected. Survivors were compared with norms and controls on neurocognitive outcomes using general linear models, and on HRQOL and social attainment using modified Poisson models. The impacts of treatment and chronic health conditions on outcomes were examined using multivariable general linear models (effect size was expressed as unstandardized β estimates that reflected the unit of change from a mean of 0 and an SD of 1) and modified Poisson models (effect size expressed as relative risks).

RESULTS

Compared with controls and population norms, survivors demonstrated lower performance on measures of verbal reasoning (mean z score, -0.45 [SD, 1.15]; P < .001) mathematics (mean z score, -0.63 [SD, 1.07]; P < .001), and long-term memory (mean z score, -0.37 [SD, 1.14]; P < .001). Cumulative anthracycline exposure (per 100 mg/m² ) was found to be associated with poorer verbal reasoning (β = -0.14 z scores; P = .04), reading (β = -0.09 z score; P = .04), and patient-reported vitality (relative risk, 1.32; 95% CI, 1.09-1.59). Neurologic and neurosensory chronic conditions were associated with poorer mathematics (neurologic conditions: β = -0.63 z score [P = 0.02]; and hearing impairment: β = -0.75 z scores [P < 0.01]). Better cognitive performance was associated with higher social attainment.

CONCLUSIONS

Long-term survivors of soft-tissue sarcoma are at risk of neurocognitive problems and poor HRQOL associated with anthracycline treatment and chronic health conditions.

Health-related quality of life, culture and communication: a comparative study in children with cancer in Argentina and Sweden

BACKGROUND

Malignant disorders in childhood are life-threatening conditions, and issues regarding the children's health-related quality of life (HRQOL) are crucial in paediatric oncology. The overall aim of this study was to explore HRQOL in children with cancer in two countries, Argentina and Sweden, which have different cultural contexts. The specific aims were: to determine HRQOL by gender, age, diagnosis, treatment modality, time since diagnosis, and parental education/employment across cultures. Further aims were to assess the child/parent relationship in HRQOL and the influence of demographic variables in psychosocial and physical HRQOL in each country.

METHODS

A cross-sectional study was performed in 2014, including 58 children (24 females, 34 males) and 62 parents/guardians. The instrument, the Pediatric Quality of Life Inventory™ (PedsQL™, generic, cancer and fatigue modules), and medical records were used. The response rate was 97%.

RESULTS

The mean age of the children was 8.67 years (SD 5.1, range 2-18 years) and the mean time on treatment was 10.7 months (SD 8.7, range 1-30 months). The most common diagnosis was leukaemia (57%). In Argentina, in comparison with Sweden, a higher estimation of generic HRQOL was reported among adolescents (p = 0.022) and more cancer-related problems among school-age children (p < 0.0001). Children and parents in both countries confirmed the major problem with fatigue and multimodality therapy regimes, but lower levels of fatigue were reported in Argentina. Adolescents and children with solid tumours appeared as vulnerable groups. In Sweden, children whose mothers had post-secondary education reported less cancer-related problems (p = 0.031). Good relationships were found between child/parent reports in Argentina regarding the fatigue module (p = 0.034) and physical subscale (p = 0.014), and in Sweden regarding generic health (p = 0.004), including psychosocial (p = 0.006) and physical subscales (p = 0.042), and cancer (p = 0.001), and fatigue (p < 0.0001) modules. In Sweden, psychosocial health (OR 7.5; p = 0.007) and physical health (OR 6.2; p = 0.011) were positively influenced by being a school-age child.

CONCLUSIONS

Fatigue is as a major problem across cultures. Still, being in school facilitates recovery. Good relationships in psychosocial HRQOL highlight professional challenges regarding severe issues and open communication, and the need of performing comparative studies of HRQOL of children with cancer from different cultural backgrounds.

The Minneapolis-Manchester Quality of Life Instrument: reliability and validity of the Adult Form in cancer survivors

PURPOSE

Childhood cancer survivors are at risk for deficits in health-related quality of life (HRQL) as they age. Youth (8-12 years) and adolescent (13-20 years) versions of the Minneapolis-Manchester Quality of Life Instrument (MMQL) have been developed to address survivor-specific issues and are currently in use; the MMQL-Adult Form has now been developed to assess HRQL in childhood cancer survivors aged 21-55 years.

METHODS

The MMQL-Adult Form was administered to 499 adults: 65 cancer patients on-therapy, 107 off-therapy, and 327 healthy controls. Forty-four percent of patients were under 30 years old at cancer diagnosis. Principal components analysis was performed. We evaluated internal consistency reliability, stability (re-administration of the MMQL-Adult Form 2 weeks later), construct validity (concurrent administration of the SF-36), and known-groups validity (score comparisons across the three groups).

RESULTS

Principal components analysis resulted in retention of 44 items across six scales: social functioning, physical functioning, cognitive functioning, outlook on life, body image, and psychological functioning. Internal consistency (Cronbach's α) was 0.80-0.90 for individual scales and 0.95 overall. Strong intraclass correlations (0.98 overall) indicated high stability. The MMQL-Adult Form distinguished between known groups; healthy controls scored better than patients on four of six scales. The MMQL-Adult Form scales correlated highly with similar SF-36 scales, demonstrating construct validity.

CONCLUSIONS

The MMQL-Adult Form is a reliable and valid self-report instrument for measuring multidimensional HRQL in cancer survivors. Development of this instrument ensures availability of a tool enabling cross-sectional and longitudinal assessment of HRQL in childhood cancer survivors as they age.

Psychopathological Aspects in Childhood Hematopoietic Stem Cell Transplantation (HSCT): The Perception of Parents and Adolescents

Background: Data about psychosocial sequelae of childhood Hematopoietic Stem Cell Transplantation (HSCT) are limited and the association with a specific donor type or other medical factors is largely unknown (Chang et al., 2012). The aim of the present study was to compare the psychological aspects of pediatric HSCT survivors with healthy peers. A secondary aim was to detect whether parents and children differed in the perception of mental health status. The influence of medical factors on psychological status was also examined. Method: Thirty seven HSCT survivors (23 males) with a mean age of 14.4 years (SD = 3.03; range 8.16-18.33) were recruited. Twenty-six patients underwent an allogenic HSCT (matched unrelated donor, n = 20; matched sibling donor, n = 6) and 11 patients received an autologous HSCT. The children psychological aspects were assessed using the Youth Self Report (YSR) (Achenbach and Rescorla, 2001) and compared to a group of matched healthy peers. At the same time, parents were requested to complete the Child Behavior Checklist 6-18 (Achenbach and Rescorla, 2001). Medical and socio-demographic data were also collected. Results: HSCT survivors reported significantly higher levels of somatic complains (t27 = 3.14; p = 0.004; mean = 3.1) when compared to healthy peers (mean = 1.5). The parent CBCL scores on "child total competence" exceeded the normative clinical cutoff in 48.6% cases. Inter-rater agreement between parent and patient reports was present only in three scales: total competence score (K = 0.06, p = 0.002), somatic complaints (K = 0.21, p = 0.003) and attention problems (k = 0.13; p = 0.02). According to Ancova models, internalizing problems were more frequent in HSCT from family donors (F2 = 3.13; p = 0.06) or in the presence of acute complications (F1 = 11.95; p = 0.003). Conclusion: In contrast to the perception of parents, pediatric HSCT survivors reported good psychological health. However, they complained about more somatic problems as compared with healthy peers. Medical aspects such as donor source and the presence of acute complications should be taken into consideration for the psychological approach in order to improve pediatric HSCT survivor care.

Nanomedicine approaches in acute lymphoblastic leukemia

Acute lymphoblastic leukemia (ALL) is the malignancy with the highest incidence amongst children (26% of all cancer cases), being surpassed only by the cancers of the brain and of the nervous system. The most recent research on ALL is focusing on new molecular therapies, like targeting specific biological structures in key points in the cell cycle, or using selective inhibitors for transmembranary proteins involved in cell signalling, and even aiming cell surface receptors with specifically designed antibodies for active targeting. Nanomedicine approaches, especially by the use of nanoparticle-based compounds for the delivery of drugs, cancer diagnosis or therapeutics may represent new and modern ways in the near future anti-cancer therapies. This review offers an overview on the recent role of nanomedicine in the detection and treatment of acute lymphoblastic leukemia as resulting from a thorough literature survey. A short introduction on the basics of ALL is presented followed by the description of the conventional methods used in the ALL detection and treatment. We follow our discussion by introducing some of the general nano-strategies used for cancer detection and treatment. The detailed role of organic and inorganic nanoparticles in ALL applications is further presented, with a special focus on gold nanoparticle-based nanocarriers of antileukemic drugs.

Physical activity and health-related quality of life in pediatric cancer patients following a 4-week inpatient rehabilitation program

PURPOSE

Chronic health conditions and impaired quality of life are commonly experienced in childhood cancer survivors. While rehabilitation clinics support patients in coping with the disease, studies evaluating an inpatient rehabilitation program on promoting physical activity (PA) and health-related quality of life (HRQoL) are missing.

METHODS

A 4-week inpatient rehabilitation program was prospectively evaluated. One hundred fifty patients with leukemia or lymphoma (N = 86), brain tumors (N = 38), and sarcomas (N = 26) were enrolled on average 17 months after cessation of acute medical treatment. PA amount and cadence (indicating the intensity of walking activity) using the StepWatch™ 3 Activity Monitor and HRQoL global and physical well-being scores using the KINDL(®) questionnaire were assessed before, immediately after, and 6 and 12 months following the program and analyzed using multiple linear mixed models.

RESULTS

Significant effects on PA were only found at 12-month follow-up for amount and cadence variables (all p < 0.05). While leukemia and lymphoma patients revealed the highest PA level throughout the study, rehabilitation effects were more pronounced for cadence variables in brain tumor and sarcoma patients. The rehabilitation program had immediate (t = 4.56, p < 0.001) and sustainable effects on HRQoL global scores (6-month follow-up, t = 4.08, p < 0.001; 12-month follow-up, t = 3.13, p < 0.006).

CONCLUSIONS

Immediate and sustainable increases in HRQoL indicate that a 4-week rehabilitation program is beneficial for improving psychosocial well-being, while the significant increase in PA levels could be related to general recovery as well. The lack of a control group hampers the evaluation of the rehabilitation program on promoting PA levels in pediatric cancer patients.

The lack of a control group hampers the evaluation of the rehabilitation program on promoting PA levels in pediatric cancer patients.

[Assessment of daily quality of life in children surviving cancer]

INTRODUCTION

The purpose of this study was to identify the daily problems experienced by school-age children in remission from cancer. It also sought to assess the predictive value of these problems on the mental health of these children 1 year after the first assessment.

PATIENTS AND METHOD

Against this background, 50 children in remission from cancer and in mainstream education, aged 8-12 years, completed two questionnaires: the Quality of Life Systemic Inventory for Children (QLSI-C) (Missotten et al., 2007) and the Child Depression Inventory (CDI). THE QLSI-C consists of 20 life areas: Sleep, Diet, Physical pain, Health, Clothing, Physical appearance, Bedroom, Grandparents, Mother, Father, Siblings, Friends, How my friends talk about me, School, School results, Sport, Non-sporting activities, Autonomy, Obedience to authority, and Tolerance of frustration. Each of these 20 life areas was evaluated by the child by reference on each occasion to an ideal situation, first in relation to their current situation and then in relation to their personal goals, in order to measure the gap between these two evaluations. This difference was then weighted by the importance given to each life area and the dynamic situation of approximation to or distance from the goals. All the children in this study were seen in person for two interviews 1 year apart (T1 and T2).

RESULTS

The analyses conducted following the PLS-PM approach enabled eight of the 20 life areas evaluated to be identified as difficult to access by the children in this study. These analyses also showed that the difficulties perceived by children in remission from cancer have mainly proximal effects (i.e., short-term) on the discomfort experienced (direct effect of difficulties expressed in T1 on discomfort felt at T1; idem for T2). However, the areas perceived as difficult at T1 did not enable distal effects (i.e., effect over a year) on the discomfort expressed in T2 to be updated. Nonetheless, the conflicts at T1 fed the conflicts at T2 and, as a consequence, indirectly affected the experience of depression at T2.

DISCUSSION

The discussion examines the nature of the daily difficulties perceived by school-age children in remission from cancer and the short-term psychological distress experienced by these children. It concludes that the difficulties encountered by children in remission from cancer are not necessarily cumulative over time and that they do not inevitably result in permanent psychological suffering.

Effects of a 6-Month, Group-Based, Therapeutic Exercise Program for Childhood Cancer Outpatients on Motor Performance, Level of Activity, and Quality of Life

BACKGROUND

Exercise interventions in pediatric oncology are feasible and safe. However, scarce data are available with regard to the effectiveness of outpatient, group-based exercise interventions. As well, the potential role of exercise to improve motor performance has not been adequately explored despite being a meaningful outcome during childhood with important implications for physical activity behavior. No study has yet demonstrated significant changes in motor performance after an exercise intervention.

PROCEDURES

This explorative, prospective study was designed to evaluate the effects of a 6-month, group-based, therapeutic exercise program for a mixed childhood cancer population on motor performance, level of activity, and quality of life. After cessation of inpatient medical treatment, childhood cancer outpatients aged 4-17 years exercised once a week during a 6-month period (IG). Comparison groups included childhood cancer outpatients receiving care as usual (CG(1)), as well as healthy peers (matched to IG by age and gender) (CG(2)).

RESULTS

Overall motor performance, various motor dimensions, activity in sport clubs and school sports, as well as physical and emotional well-being were significantly reduced in the IG at baseline. Significant differences between the IG and CG(1) and/or CG(2) were identified in the change of overall motor performance, single motor dimensions, overall level of activity, and emotional well-being from baseline to post-intervention.

CONCLUSIONS

The exercise intervention was beneficial in terms of motor performance, level of activity, and emotional well-being. As such, this study provides support for group-based exercise as a potential strategy to improve these outcomes after inpatient medical treatment.

Psychological distress between young adult female survivors of childhood cancer and matched female cohorts surveyed in the adolescent health study

BACKGROUND

The psychological health of childhood cancer survivors is an essential treatment outcome. Female survivors are a subgroup of survivors with an increased risk for poor psychological outcomes.

OBJECTIVE

This study compared psychological distress in young adult female survivors of childhood cancer with that in young adult females in the general population with no history of childhood cancer. Psychological distress was measured by assessing respondents' subjective degree of depressive symptoms, anxiety, and somatization.

METHODS

The study was a secondary data analysis. The sample was drawn from the National Longitudinal Study of Adolescent Health, which used a representative, probability-based sampling technique. The sample included 66 young adult female survivors of childhood cancer and 8186 young adult females with no history of cancer. Randomized, nonparametric testing was used to construct 10 000 different age-matched female cohort samples from the general population.

RESULTS

Young adult female survivors of childhood cancer had more depressive symptoms (P < .05) as compared with matched cohorts with 589 of the 10,000 matched samples. There were no statistically significant differences between the cancer survivors and the matched cohort groups on anxiety and somatization symptoms.

CONCLUSION

Young adult female survivors of childhood cancer are at an increased risk of experiencing depression, which can decrease their psychological functioning and emotional well-being.

IMPLICATIONS FOR PRACTICE

Healthcare professionals who care for these cancer survivors need to be aware that female survivors are at risk for depression and should screen and refer accordingly.

Activities of Daily Living in Survivors of Childhood Brain Tumor

OBJECTIVE. This cross-sectional, descriptive study evaluated the performance in activities of daily living (ADLs) of youth and young adult survivors of childhood brain tumor (BT) and explored associations with health-related quality of life (HRQoL).

METHOD. Thirty-six participants were examined using the Assessment of Motor and Process Skills to evaluate their quality of ADL task performance and the Medical Outcomes Study 12-Item Short-Form Health Survey (SF–12) to evaluate HRQoL.

RESULTS. Participants had significantly lower performance in ADLs compared with age norms (p &lt; .05), and their functional level was positively associated with the SF–12 Physical (r 2 = .5) and Mental (r 2 = .3) scales.

CONCLUSION. Participants had significant limitations in both motor and process skills, which affected their performance in ADLs. Study results emphasize the importance of long-term follow-up and rehabilitation services aimed at improving the functional level and HRQoL of BT survivors.

Health status and quality of life of long-term survivors of childhood acute leukemia: the impact of central nervous system irradiation

We evaluated the impact of central nervous system irradiation (CNSI) on long-term health status and quality of life (QoL) of childhood lymphoblastic leukemia survivors included in the French L.E.A. (Childhood and Adolescent Leukemia) multicentric cohort. QoL was self-reported in adults and assessed by parents in children and adolescents, using adapted questionnaires. From 2004 to 2009, 630 nongrafted patients were assessed after 11.8±6.3 years from diagnosis. Patients receiving CNSI (18.6%) or chemotherapy alone (81.4%) were compared. The risk of having long-term physical effects was increased with CNSI (odds ratio=3.3; 95% confidence interval, 1.8-5.9), especially regarding growth failure, second tumor, cataract, and overweight. QoL did not differ significantly according to the treatment received, despite a tendency toward lower scores with CNSI in children and adolescents (summary score 63.6±13.3 vs. 71.7±12.4, P=0.14). Compared with French norms, adult survivors had an impaired QoL, especially in mental domains (mental composite score 45.2±9.8 vs. 47.9±2.1, P<0.001). In pediatric survivors, QoL was not impaired and even tended to be higher than population norms (summary score 71.7±12.4 vs. 70.0±4.2, P=0.054), mainly in social and relational domains. In conclusion, QoL seems to be impaired by the trauma of a life-threatening illness in childhood, as well as by the treatment received.

Screening for Distress in Young People After Treatment for Sarcoma: A Feasibility Study

Few validated tools are available in childhood cancers settings to assess distress and worry. Twenty-one young people (mean age = 14 years), with an average 4 years since diagnosis, attended a sarcoma follow-up clinic and were asked to complete questionnaires assessing general mood and behavior, quality of life, and distress. All young people completed the Distress Thermometer. However, as the age range was quite wide (9-18 years), different questionnaires were also used with different age groups to assess feasibility and acceptance. In addition, young people were asked for their views about the questionnaires they had completed, asked about previous psychological support, and were asked to rate how useful they had found the medical appointment. Finally, they were asked whether or not they would like a member of the psychology team to contact them to discuss any issues that had been raised by the questionnaires. Patients reported impaired health status and worry about lifestyle, daily activities, and emotional well-being. A health-related quality of life measure (EQ-5D) and an adapted version of the Distress Thermometer were more sensitive than traditional measures and may serve as useful tools to screen for psychological concerns in busy clinical settings.

Surviving cancer: The psychosocial outcomes of childhood cancer survivors and its correlates

This study assessed the psychosocial outcomes of adolescent cancer survivors and their relationship with personal and socio-familiar factors. Using a cross-sectional design, 41 survivors answered the four psychosocial dimensions of the KIDSCREEN-52 questionnaire and measures for social support and coping. Similarly, 41 parents answered coping and cancer-related distress measures. All psychosocial scores were within normative values (50 ± 10). Multiple linear regression analyses revealed four models with a range of explained variance between 9.4 percent and 31.9 percent that include the informative and emotional support, parental distress, and coping. This study contributes to the understanding of psychosocial outcomes of childhood cancer survivors and its correlates.

Survivors of childhood cancer report high levels of independence five years after diagnosis

The aim was to compare self-rated independence in childhood cancer survivors 5 years after diagnosis with corresponding ratings during initial cancer treatment and those in a comparison group. A further aim was to determine whether and how certain clinical and demographic variables affected self-rated independence. Self-rated independence, a dimension included in the health-related quality of life (HRQoL) measure DISABKIDS Chronic Generic Measure (DCGM-37), was assessed in a Swedish cohort of survivors (n = 63, aged 12-22 years) and compared with ratings during initial cancer treatment and those in an age-matched comparison group (n = 257). Potential predictors of self-rated independence were estimated using multiple regression analysis. Survivors rated their independence significantly higher 5 years after diagnosis than during initial cancer treatment and higher than the comparison group. Neither demographic nor clinical variables (age, sex, diagnosis, initial cancer treatment) predicted self-rated independence 5 years post diagnosis. Five years after diagnosis, survivors of childhood cancer appear to have reached a satisfactory level of independence. However, survivors are likely to experience complications over the longer term, and therefore continued follow-up is warranted to follow possible changes in self-reported independence.

Quality of life outcomes in proton and photon treated pediatric brain tumor survivors

BACKGROUND

Radiotherapy can impair Health Related Quality of Life (HRQoL) in survivors of childhood brain tumors, but proton radiotherapy (PRT) may mitigate this effect. This study compares HRQoL in PRT and photon (XRT) pediatric brain tumor survivors.

METHODS

HRQoL data were prospectively collected on PRT-treated patients aged 2-18 treated at Massachusetts General Hospital (MGH). Cross-sectional PedsQL data from XRT treated Lucile Packard Children's Hospital (LPCH) patients provided the comparison data.

RESULTS

Parent proxy HRQoL scores were reported at 3 years for the PRT cohort (PRT-C) and 2.9 years (median) for the XRT cohort (XRT-C). The total core HRQoL score for the PRT-C, XRT-C, and normative population differed from one another and was 75.9, 65.4 and 80.9 respectively (p=0.002; p=0.024; p<0.001). The PRT-C scored 10.3 and 10.5 points higher than the XRT-C in the physical (PhSD) and psychosocial (PsSD) summary domains of the total core score (TCS, p=0.015; p=0.001). The PRT-C showed no difference in PhSD compared with the normative population, but scored 6.1 points less in the PsSD (p=0.003). Compared to healthy controls, the XRT-C scored lower in all domains (p<0.001).

CONCLUSIONS

The HRQoL of pediatric brain tumor survivors treated with PRT compare favorably to those treated with XRT and similar to healthy controls in the PhSD.

Adolescents' and young adults' experiences of childhood cancer: descriptions of daily life 5 years after diagnosis

BACKGROUND

Survivors of childhood cancer are a growing population in society. These young people have a high risk of developing chronic health problems with a potential strong impact on their lives. How a childhood cancer experience affects survivors in adolescence has been studied to a limited extent; an increased understanding of this young group is needed to improve follow-up care.

OBJECTIVE

The aim of this study was to gain a deeper understanding of how childhood cancer affects the lives of survivors by exploring adolescents' and young adults' views of what it is like living with this experience.

METHODS

Fifty-nine 11- to 22-year-olds were interviewed a median of 5 years after a cancer diagnosis (response rate, 66%). Data were collected through telephone interviews and were analyzed using qualitative content analysis techniques.

RESULTS

Three groups of informants were identified according to their descriptions of the influence of cancer treatment on their daily life: "feeling like anyone else" (informants who described that the cancer experience had almost no influence on current life) (49%), "feeling almost like others" (those who described some influence) (44%), and "feeling different" (those describing a great influence on current life) (7%).

CONCLUSIONS

Most of the adolescents and young adults appear to get along well, although many informants described that life was affected to some extent by having had cancer.

IMPLICATIONS FOR PRACTICE

Follow-up care is needed that can identify those young survivors of childhood cancer having trouble with daily life and offer them support to strengthen their resources in managing difficulties in relation to having had cancer.

Clinical significance in self-rated HRQoL among survivors after childhood cancer - demonstrated by anchor-based thresholds

BACKGROUND

There is a need to establish clinically relevant thresholds (anchors) for identification of differences in health-related quality of life (HRQoL) and thereby provide stronger evidence regarding the HRQoL of childhood cancer survivors.

AIM

To investigate HRQoL in childhood cancer survivors with a standardised instrument and to establish thresholds for clinically significant differences by using qualitative interviews as anchors. An additional aim was to investigate survivors' HRQoL in relation to an age-matched comparison group without cancer experience.

MATERIAL AND METHODS

Self-rated HRQoL (KIDSCREEN-27) was assessed in a national cohort of survivors (n = 63, aged 12-22) and a comparison group (n = 257, aged 11-23). Findings from qualitative interview data were also used (n = 61); three subgroups ("Feeling like anyone else"; "Feeling almost like others"; "Feeling different") were identified based on survivors own perception of influence on daily life. Effect size calculations based on means from the KIDSCREEN-27 dimensions were performed using the subgroups as anchors to indicate clinical importance. Furthermore, standard multiple regression analyses were performed. Results. Effect sizes between the subgroups "Feeling like anyone else" and "Feeling almost like others" and the group "Feeling different" were large for all dimensions (1.04-2.07). The multiple regression models showed that being a survivor was significantly associated with one of the dimensions, School Environment, where survivors scored higher HRQoL. Furthermore, female sex and older age (17-23 years) significantly contributed to lower self-rated HRQoL. Conclusion. In clinical practice the KIDSCREEN-27 could be a useful screening tool to identify survivors of childhood cancer in need of extra support, using KIDSCREEN dimension mean values of 45 or less as thresholds. Larger scale studies are recommended to identify and test thresholds with regard to different age groups and time since diagnosis.
