Health-related quality of life in pediatric cancer survivors: a multifactorial assessment including parental factors

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.

Burden of Childhood Cancer and the Social and Economic Challenges in Adulthood: A Systematic Review and Meta-Analysis

Importance

Significant advancements in pediatric oncology have led to a continuously growing population of survivors. Although extensive research is being conducted on the short-, medium-, and long-term somatic effects, reports on psychosocial reintegration are often conflicting; therefore, there is an urgent need to synthesize the evidence to obtain the clearest understanding and the most comprehensive answer.

Objective

To provide a comprehensive review and analysis of the socioeconomic attainment of childhood cancer survivors (CCSs) compared with their unaffected peers.

Data Sources

A systematic review and meta-analysis was conducted using data obtained from a comprehensive search of MEDLINE (via PubMed), Embase, and CENTRAL (Cochrane Central Register of Controlled Trials) databases on October 23, 2021; the search was updated until July 31, 2023.

Study Selection

Eligible articles reported on educational attainment, employment, family formation, quality of life (QoL), or health-risk behavior-related outcomes of CCSs, and compared them with their unaffected peers. Study selection was performed in duplicate by 4 blinded independent coauthors.

Data Extraction and Synthesis

Data extraction was performed in duplicate by 4 independent authors following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Outcome measures were odds ratios (ORs) and mean differences with 95% CIs; data were pooled using a random-effects model.

Results

The search identified 43 913 articles, 280 of which were eligible for analysis, reporting data on a total of 389 502 survivors. CCSs were less likely to complete higher levels of education (OR, 0.69; 95% CI, 0.40-1.18), had higher odds of health-related unemployment (OR, 2.94; 95% CI, 1.90-4.57), and showed lower rates of marriage (OR, 0.72; 95% CI, 0.63-0.84) and parenthood (OR, 0.60; 95% CI, 0.49-0.74) compared with population-based controls.

Conclusion and Relevance

Study findings suggest that CCSs face several socioeconomic difficulties; as a result, the next goal of pediatric oncology should be to minimize adverse effects, as well as to provide lifelong survivorship support aimed at maximizing social reintegration.

Feasibility Study of Taking Back Control Together, an Intervention to Support Parents of Children with Cancer

INTRODUCTION

Parents of children with cancer can experience increased emotional distress. This study aimed to assess the feasibility (i.e., reach, treatment fidelity, and social validity) of Taking Back Control Together (TBCT).

METHODS

We assessed reach with the enrollment and dropout ratios. We assessed treatment fidelity using items from existing programs, controlling for the reliability of the items. For social validity, we used an adapted version of the Treatment Evaluation Inventory and compared means with theoretical cut-points.

RESULTS

42 participants enrolled in the intervention. The enrollment and dropout ratios were 39% and 38%, respectively. Treatment fidelity was 77.3-84.3% (95%CI 75.3-86%). Acceptability (M = 90%), satisfaction (M = 87%), and relevance (M = 82%) were significantly positive.

CONCLUSION

This study suggests that certain elements of TBCT need to be reassessed before the intervention is pilot tested. Although reach was likely impacted by the COVID-19 pandemic, it could be improved with some modifications to the intervention.

Relationships Between Parental Anxiety and Child Quality of Life in Advanced Childhood Cancer

Background: Family factors, such as household income and parental psychosocial distress, have been associated with quality of life in children with cancer. However, relationships between parent anxiety and child health-related quality of life (HRQoL) have not been evaluated in children with advanced cancer. Objective: To examine relationships between parent anxiety and both parent-reported and child self-reported HRQoL for children with advanced cancer. Method: Children (aged 5-17 years) with relapsed or refractory cancer and their parents participated in this single-institution cross-sectional study. Parents completed measures of their own baseline anxiety (State-Trait Anxiety Inventory-Trait [STAI-T] form) and their ill child's HRQoL (PedsQL Generic and PedsQL Cancer, parent report). Children completed age-specific PedsQL Generic and PedsQL Cancer, child report. Spearman's rho coefficients assessed correlations between total parent STAI-T score and both parent-reported and child-reported HRQoL scales. Results: Twenty children (Mage = 9.5 years, 50% female) and their 20 parents (90% mothers) participated. The strongest and statistically significant (p < .05) correlations were inverse associations between parental trait anxiety and parent-reported child psychosocial HRQoL (rs = -.54), emotional functioning (rs = -.49), school functioning (rs = -.45), and child pain and hurt (rs = -.45). Correlations of parental anxiety with all dimensions of child-reported HRQoL were generally smaller (rs < .40), positive, and not statistically significant (p > .05). Discussion: Given the inverse correlations between parental anxiety and child psychosocial HRQoL, assessment of parent mental health needs and access to interventions should be provided routinely for parents of children with advanced cancer.

Cardiorespiratory fitness and health-related quality of life in survivors of childhood central nervous system tumours

PURPOSE

We assessed cardiorespiratory fitness and health-related quality of life (HRQoL) in survivors of childhood central nervous system (CNS) tumours.

METHODS

Participants were recruited from the National Children's Cancer Service in Children's Health Ireland at Crumlin. Inclusion criteria included diagnosis of a primary CNS tumour, aged between 6 and 17 years, between 3 months and 5 years post completion of oncology treatment, independently mobile, and deemed clinically appropriate to participate by treating oncologist. Cardiorespiratory fitness was assessed using the six-minute walk test. HRQoL was assessed with the PedsQL Generic Core Scales, Version 4.0.

RESULTS

Thirty-four participants (n = 16 male) were recruited, with a mean age of 12.21 ± 3.31 years and a mean time since completion of oncology treatment of 2.19 ± 1.29 years. Mean six-minute walk distance (6MWD) achieved was 489.56 ± 61.48 m, equating to the 8^th percentile overall. 6MWD was significantly reduced when compared to predicted population norms (p < 0.001). PedsQL parent proxy-report and child-report scores were significantly lower when compared to healthy paediatric norms (p < 0.001 - p = 0.011). A significant positive correlation was found between 6MWD and both parent proxy-report (r = 0.55, p < 0.001) and child-report (r = 0.48, p = 0.005) PedsQL total scores.

CONCLUSION

Survivors of childhood CNS tumours present with impaired cardiorespiratory fitness and HRQoL. Higher levels of cardiorespiratory fitness are associated with higher levels of HRQoL.

IMPLICATIONS FOR CANCER SURVIVORS

Routine screening of cardiorespiratory fitness and HRQoL in survivors of childhood CNS tumours may be beneficial. Healthcare providers should encourage and provide education on the potential benefits of physical activity to improve overall quality of life.

Evaluation of disease related attitudes and quality of LIFE in children with chronic illness

AIM

This study was conducted as a descriptive method in order to evaluate the attitudes towards illness of children with chronic diseases and their quality of life.

METHOD

The population of the study consisted of children with a chronic illness who were admitted to the pediatrics outpatient clinic of a hospital located in a province in the north-east of Turkey. The sample of the study consisted of 105 children who came to the hospital between October 2020 and June 2022, who met the criteria, and whose permission was obtained from themselves and their families. The study data were collected by using the 'Introductory Information Form', the 'Pediatric Quality of Life Inventory (PedsQL) (8-12 and 13-18 years)' and the 'Child Attitude Towards Illness Scale (CATIS)'. Data were analyzed using the SPSS for Windows 22 package program.

RESULTS

The mean age of the children who participated in the study was 13.90 ± 2.55 and 73.3% of them were in the adolescent age group. The average PedsQL total score of the children participating in the research was 64.59 ± 18.99 and the average CATIS total score was 3.05 ± 0.71.

CONCLUSION

It was determined that as the quality of life of the children with chronic diseases in the study increased, their attitudes towards their diseases became more positive.

PRACTICE IMPLICATIONS

While caring for children with chronic diseases, nurses should consider that supporting the child's quality of life positively affects the child's attitude towards the disease.

Evaluation of health-related quality of life in childhood cancer survivors

BACKGROUND

Considering the high survival rates of childhood cancers and their stable incidence, concepts such as quality of life (QOL) and health-related quality of life (HRQOL) are impactful issues that have consistently retained their importance worldwide.

OBJECTIVE

This study aimed to evaluate HRQOL at least 5 years after treatment in childhood cancer survivors (CCSs) with the hypothesis that their QOL could be adversely affected later in their lives. Additionally, we sought to assess the parents of pediatric CCSs with respect to HRQOL.

PATIENTS AND METHODS

We evaluated CCSs aged 8-18 years and compared the results with healthy controls (matched for age and sex). The parents of the pediatric CCSs and control groups were also analyzed. A total of 174 cases (patients and controls) and 168 parents (of patients and controls) were included in the study. HRQOL was evaluated by applying the Pediatric Quality of Life Inventory (PedsQL).

RESULTS

The mean HRQOL scores of CCSs were significantly lower than those of the controls (p= 0.04). No differences were found between the parents of these groups. The physical and social functionality scores of CCSs were significantly lower when compared to healthy controls (p = 0.02 and p<0.01, respectively). In addition, according to cancer type, the HRQOL scores of those with solid tumors were found to be significantly lower than those with hematological cancers (p=0.02).(p = 0.02) CONCLUSION: This study shows that HRQOL is lower in CCSs compared to healthy controls. The most important differences in HRQOL among CCSs were found in the physical and social subdimensions compared to the controls. In this regard, it appears to be vital to provide mental support to CCSs after cancer treatment. These findings also indicate the need for health-focused social policies that can increase HRQOL in CCSs.

Translation and evaluation of psychometric properties of the Amharic pediatric quality of life inventory 4.0 generic core scale for children with cancer

BACKGROUND

Childhood cancer negatively impacts a child's physical, mental, and behavioural health and significantly affects their health-related quality of life. The Pediatric Quality of Life Inventory 4.0 Generic Core Scale (PedsQL™ 4.0 GCS) is one of the most commonly used measures of the quality of life in children. However, the Amharic version of PedsQL™ 4.0 GCS has not been validated in a paediatric oncology population. This study aimed to translate and evaluate the psychometric properties of the Amharic PedsQL™ 4.0 GCS (PedsQL™ 4.0 GCS (A)) for Ethiopian children with cancer.

METHODS

A descriptive cross-sectional study was conducted among children aged 8-18 years with any type of cancer across the cancer trajectory. Cronbach's alpha and intraclass correlation coefficient were computed to determine the internal consistency and test-retest reliability of the scale. The convergent validity was established by examining the correlation of the PedsQL™ 4.0 GCS (A) with the Amharic version of the Revised Child Anxiety and Depression Scale (RCADS-25(A)). Factorial validity was evaluated by conducting a confirmatory factor analysis.

RESULTS

The study included 142 participants with childhood cancer. PedsQL™ 4.0 GCS (A) had good validity and reliability. It demonstrated high internal consistency with a Cronbach's alpha of 0.96 for the scale and 0.82-0.95 for the subscales. The intraclass correlation coefficient for the scale was 0.9 and that for the subscales was 0.76-0.90. The PedsQL™ 4.0 GCS (A) was highly correlated with RCADS-25 (A) (r = - 0.97, p < 0.001), supporting its convergent validity. The four-factor structure of the model fitted the data satisfactorily (χ²/df = 1.28; CFI = 0.97; TLI = 0.97; RMSEA = 0.05; SRMR = 0.05), supporting the factorial validity of the PedsQL™ 4.0 GCS (A).

CONCLUSION

The PedsQL™ 4.0 GCS (A) demonstrates desirable psychometric properties for assessing quality of life among Ethiopian children with cancer. The scale can be used in clinical settings for assessing and evaluating quality of life in children with cancer. The use of parent-report versions and studies in those with different health conditions and healthy populations are necessary to further establish the psychometric properties of the PedsQL™ 4.0 GCS (A).

Comparison of psychosocial adaptations among childhood cancer survivors, their siblings and peers in Taiwan

PURPOSE

This study aimed to understand the difference in psychosocial adaptation among childhood cancer survivors, their healthy siblings and peers, and the factors affecting the psychosocial adaptation of these cancer survivors.

DESIGN AND METHODS

A total of 222 children (ages 8-17) including childhood cancer survivors, their siblings, and healthy peers participated in this cross-sectional study. All the children completed the anxiety and quality of life scales for their age groups.

RESULTS

Anxiety levels and quality of life were similar among the childhood cancer survivors, their siblings, and their peers. The anxiety of elementary school-age survivors of acute leukemia was higher than that of those with solid tumors. Elementary school-age survivors who completed three or more years of treatment had lower anxiety than those who completed treatment within the three years. For adolescent survivors, the higher their body mass index, the higher their anxiety, which was associated with low quality of life. Those diagnosed with anxiety and at an older age had lower quality of life.

CONCLUSIONS

Although there were no differences in survivors' psychosocial adaptation compared to their siblings and healthy peers, more than half of these adolescents had moderate to severe anxiety. Future study may need to explore the causes of their anxiety.

PRACTICE IMPLICATIONS

During the follow-ups of the childhood cancer survivors, age-specific adaptive strategies can be discussed to reduce their anxiety and improve their quality of life.

Associations of Physical Activity and Handgrip Strength with Different Domains of Quality of Life in Pediatric Cancer Survivors

There is a paucity of evidence about the associations of physical activity (PA) and handgrip strength (HGS) within different domains of quality of life (QoL) in Chinese pediatric cancer survivors. We, therefore, conducted this multicenter cross-sectional study aimed to investigate whether increased PA level and HGS are associated with higher scores in different QoL domains (i.e., physical, emotional, social, and school functioning) in pediatric cancer survivors. PA was assessed with a validated self-reported PA rating scale. In total, 191 Chinese pediatric cancer survivors aged 9 to 16 years were included in the analysis. Results showed that engaging in a higher level of PA was significantly associated with improved QoL in different domains, including physical (β = 0.543, p < 0.001), emotional (β = 0.449, p < 0.001), social (β = 0.434, p < 0.001), and school functioning (β = 0.407, p < 0.001). Greater HGS was also associated with better physical (β = 0.230, p ≤ 0.001) and emotional (β = 0.261, p ≤ 0.001) functioning. Findings from this study provide evidence of the significant beneficial impact of regular PA on pediatric cancer survivors’ QoL along their survivorship trajectory.

The effects of administered interventions on quality of life of children with cancer in Turkey: A systematic review and meta-analysis

OBJECTIVE

The present systematic review and meta-analysis aimed to analyse the effects of administered interventions on the quality of life of children with cancer in Turkey.

METHODS

The quantitative studies conducted with paediatric oncology patients, analysing the quality of life of Turkish children, and published papers from 2009 to 2019 were searched. Joanna Briggs Institution MAStARI Experimental and Quasi-Experimental Research Control List and Quality Index were used for methodological assessment. Five studies comprising a total of 264 samples were included. Four studies were nonrandomised controlled trials, and one was a quasi-experimental study.

RESULTS

Tests for heterogeneity showed that the studies, which included interventions increasing the quality of life of children with cancer, were heterogeneous. The common effect size of all studies on quality of life was determined as having a strong positive effect.

CONCLUSIONS

This meta-analysis and systematic review contribute to the knowledge of Turkish health care professionals regarding these interventions by producing results with high levels of evidence on the improvement of the quality of life among children with cancer. The present study also significantly raises awareness and encourages health care professionals to implement interventions for the improvement of quality of life among children with cancer.

Long-term health-related quality of life in young childhood cancer survivors and their parents

PURPOSE

Few studies have investigated the health-related quality of life (HRQoL) of young childhood cancer survivors and their parents. This study describes parent and child cancer survivor HRQoL compared to population norms and identifies factors influencing child and parent HRQoL.

METHODS

We recruited parents of survivors who were currently <16 years, and >5 years postdiagnosis. Parents reported on their child's HRQoL (Kidscreen-10), and their own HRQoL (EQ-5D-5L). Parents rated their resilience and fear of cancer recurrence and listed their child's cancer-related late effects.

RESULTS

One hundred eighty-two parents of survivors (mean age = 12.4 years old and 9.7 years postdiagnosis) participated. Parent-reported child HRQoL was significantly lower than population norms (48.4 vs. 50.7, p < .009). Parents most commonly reported that their child experienced sadness and loneliness (18.1%). Experiencing more late effects and receiving treatments other than surgery were associated with worse child HRQoL. Parents' average HRQoL was high (0.90) and no different to population norms. However 38.5% of parents reported HRQoL that was clinically meaningfully different from perfect health, and parents experienced more problems with anxiety/depression (43.4%) than population norms (24.7%, p < .0001). Worse child HRQoL, lower parent resilience, and higher fear of recurrence was associated with worse parent HRQoL.

CONCLUSIONS

Parents report that young survivors experience small but significant ongoing reductions in HRQoL. While overall mean levels of HRQoL were no different to population norms, a subset of parents reported HRQoL that was clinically meaningfully different from perfect health. Managing young survivors' late effects and improving parents' resilience through survivorship may improve HRQoL in long-term survivorship.

Relationships between executive functions and occupational performance of children with medulloblastoma

Introduction

This study examines executive functions and occupational performances of children with medulloblastoma and children with typical development. The aim was to compare the executive function and occupational performance levels of children with medulloblastoma and children with typical development and to investigate the relationship between the executive function and occupational performance levels of children with medulloblastoma.

Method

Parents of 105 children (6–12 years) completed the Childhood Executive Function Inventory. A total of 105 children were administered the Canadian Occupational Performance Measurement to obtain information on occupational performance areas. Executive functions and occupational performance levels of children with medulloblastoma ( n = 52) and typical development ( n = 53) were compared. Correlation analysis was conducted between the executive functions and occupational performances of children with medulloblastoma.

Results

Executive function and occupational performance levels of children with medulloblastoma were lower than those with typical development. Significant relationships were found between the executive functions and occupational performances of children with medulloblastoma ( p < 0.05, p < 0.001).

Conclusion

It is clear that the executive functions of children with medulloblastoma significantly affect their occupational performance level. Client-centered, occupation-oriented cognitive therapy interventions prepared according to occupational therapy theories and models might be useful to increase the occupational performance level of children with medulloblastoma.

Telling the Story of Childhood Cancer-The Experience of Families After Treatment

Background:

The Discovery Interview methodology was introduced to Oncology Services Group in 2012 as a service improvement strategy and was evaluated positively by staff and families. It enabled clinical staff to hear the deidentified families’ stories, understand their experience, and implement process and practice enhancements.

Objective:

This study collected family stories following treatment for childhood cancer at the tertiary center in Queensland, with the goal of raising awareness and improving family experience.

Method:

Twenty-five families were interviewed via an interview spine which covered the major stages of cancer treatment and themes were extracted.

Results:

Major themes were psychological support needs, adapting to the new normal, and rebuilding relationships. After treatment, the parent had time to reflect on their experience and lost the reassurance of regularly attending the tertiary hospital. There was ongoing anxiety regarding relapse. Parents reported various coping strategies and some wanted to maintain contact with other oncology families. Families strived to get back to a level of normality such as attending school and experienced some challenges in relationships with family and friends.

Conclusion:

Families needed support and reassurance from their local health professionals to navigate the ongoing challenges following treatment.

Feeding and Growth in Infants With Cleft Lip and/or Palate: Relationships With Maternal Distress

OBJECTIVE

To examine relationships between early feeding and growth and maternal distress in infants with and without cleft lip and/or palate (CL/P).

DESIGN

Cross-sectional.

SETTING

Pediatric academic medical center in the Midwestern United States.

PARTICIPANTS

Mothers of infants 1 to 12 weeks old with CL/P (n = 30) and without CL/P (control group, n = 30) were recruited at craniofacial clinic or pediatrician appointments.

MAIN OUTCOME MEASURE(S)

Maternal responses on the Feeding/Swallowing Impact Survey (FS-IS), Parenting Stress Index, Fourth Edition, Short Form (PSI-4-SF), and Edinburgh Postnatal Depression Scale. Infant feeding history and growth measurements were obtained.

RESULTS

Having an infant with CL/P revealed greater impact on maternal health-related quality of life due to feeding problems (F = 4.83, P = .03). Mothers of infants with CL/P reported average range Total Stress scores on the PSI-4-SF, which were higher than controls (F = 4.12, P = .05). Edinburgh Postnatal Depression Scale scores did not differ between groups. Compared to controls, infants with cleft palate had lower percentiles for weight (t = 4.13, P = .04) and length (t = 2.93, P = .01). Higher FS-IS scores were associated with longer feeding duration (r = 0.32, P = .01) and lower weight (r = -0.31, P = .02) and length (r = -0.32, P = .02).

CONCLUSIONS

Despite receiving early team care and feeding interventions, mothers of infants with CL/P reported higher stress and more challenges with feeding and growth. Future studies should examine targeted psychosocial interventions to improve feeding and growth outcomes in infants with CL/P.

A Multidisciplinary Approach to Pediatric Feeding Disorders: Roles of the Speech-Language Pathologist and Behavioral Psychologist

Purpose Pediatric feeding disorders (PFDs) present as a complex clinical challenge because of the heterogeneous underlying etiologies and their impact on health, safety, growth, and psychosocial development. A multidisciplinary team approach is essential for accurate diagnosis and prompt interventions to lessen the burdens associated with PFDs. The role of the speech-language pathologist (SLP) as a member of the multidisciplinary team will be highlighted. Method This clinical focus article reviews the definition of PFDs and pertinent literature on factors that contribute to the development of PFDs, the accurate diagnosis, and current interventions for infants and children. As part of the multidisciplinary team, the SLP has an integral role in determining whether a child cannot or will not eat and working with the team to identify and carryout appropriate interventions. Collaboration between SLPs and psychologists/behavioral specialists in conjunction with the parents/caregivers as part of the multidisciplinary team is essential to the advancement of therapeutic goals. Conclusions Due to their complex nature, the successful management of PFDs is only possible with the care and expertise of a multidisciplinary team, which includes parents/caregivers. SLPs are important members of these multidisciplinary teams and provide valuable input for the accurate identification and effective remediation of PFDs.

Reliability and validity of the revised impact on family scale (RIOFS) in the hospital context

BACKGROUND

The lack of formal instruments to measure Burden in primary caregivers of Children in a hospital context is limited because mostly of published instruments are related to cancer survivors, ambulatory environment or general context for children with chronic conditions, but none of them adapted property to prolonged hospitalization context. This leaves the rising population of hospitalized chronic children's caregivers without a proper assessment. The aim of this study was to develop a version of the Revised Impact on Family Scale adapted to primary caregivers of chronic hospitalized children. A cross-sectional study with two main stages was conducted. The first one describes the linguistic and contextual adaptation process of the instrument, and the second refers to the psychometric testing and analysis..

RESULTS

Less than 15% of the participants expressed problems with some adapted items in the scale. Eighty-six caregivers were evaluated at Josefina Martinez Hospital, mostly female (34.2 ± 11.6 years old). Majority of participants were graduated from high school, salaried employee and mothers of the chronic child. The scale exhibits a high level of internal consistency (Cronbach's alpha 0.73), excellent intra-observer reliability (Intraclass Correlation Coefficient 0.9), acceptable empirical evaluation of content validity and low and negative construct validity (Pearson's correlation coefficient - 0.23).

CONCLUSIONS

This adapted version of the Revised Impact on Family Scale to the hospital context is a reliable, valid, self-administered and simple instrument to implement in order to assess the burden of primary caregivers with chronic hospitalized children.

THE CORRELATION BETWEEN FAMILY FUNCTIONING AND QUALITY OF LIFE OF CAREGIVER OF CHILDREN WITH LEUKEMIA

Background: Quality of life of caregiver of children with leukemia is important because it can affect the quality of care provided and can affect the health of children and the caregiver themselves. One of the factors that influence the caregiver’s quality of life is the family functioning. However, a few number of research on the correlation of family functioning in the caregiver's situation. Objective: The aim of the study was to analyze the correlation between family functioning and the caregiver’s quality of life of children with leukemia. Methods: This study used a Quality of Life Family Version questionnaire and a Family Assessment Device questionnaire. The populations in this study were all parents (father or mother) who were the primary caregiver of children with leukemia aged 0-15 years and were being treated at a referral hospital in West Java, Indonesia. Thirty-two respondents were determined by a total sampling technique. The data analysis used frequency distribution and chi-square. Results: The results showed that the family functioning and quality of life of the caregiver had the same results, 50% good and 50% poor. Correlation test in this study showed a negative value with p value > 0.05 (0.480), which indicated that there was no correlation between family functioning and the quality of life of the caregiver. Conclusion: The correlation between family functioning and caregiver's quality of life was not significant. This is likely due to the variable family functioning and the caregiver’s quality of life having balanced results. The results of this study need to be followed up by providing nursing care holistically not only to children, but also to families, especially who are directly involved in child care.

Definition and improvement of the concept and tools of a psychosocial intervention program for parents in pediatric oncology: a mixed-methods feasibility study conducted with parents and healthcare professionals

Background

Studies have shown that supporting parents in pediatric oncology reduces family distress following a cancer diagnosis. Manualized programs for parents have therefore been developed to reduce family distress. However, these programs have limitations that need to be improved, such as better defining programs’ procedures, developing interventions focusing on parents’ conjugal relationship, conducting rigorous evaluations of implementation, and proposing adaptations to various cultural dimensions. According to the Obesity-Related Behavioral Intervention Trials (ORBIT) model for the development of behavioral intervention, we improved these limitations and developed TAKING BACK CONTROL TOGETHER, a six in-person intervention sessions to support parents of children with cancer by taking the active components of two programs: Bright IDEAS and SCCIP. Referring to the redesign phase of the ORBIT model, this study aims to refine the definition of this program’s design by interviewing parents and healthcare professionals.

Methods

In order to refine the program, we used a sequential mixed-methods study. Parents and healthcare professionals first completed questionnaires assessing the program, and then discussed its limitations, benefits, and areas for improvement in group and/or individual interviews. We performed a descriptive thematic content analysis of the qualitative data from the open-ended questions (questionnaires and interviews) with NVivo 11 to categorize recommendations for the program refinement.

Results

The results showed that components seemed pertinent to final users. The main areas needing improvement were the level of complexity and understandability of the parent manual, the possibility to choose the place and time of the intervention, and the lack of ethnic/cultural diversity. Changes to the program were made accordingly.

Conclusions

It is necessary to include end-users when developing complex intervention programs designed for vulnerable populations and sensitive clinical contexts. Following the present refinement, we now have a treatment package, which is safe and acceptable for the target population and has a better chance of yielding a clinically significant benefit for users in a future pilot study.

Synchronous Bilateral Wilms Tumor: Five-Year Single-Center Experience with Assessment of Quality of Life

Context:

Synchronous Bilateral Wilms tumor (sBWT).

Aims:

This study aimed to assess the outcome of patients with sBWT treated on SIOP protocol.

Settings and Design:

Retrospective and prospective randomized study.

Subjects and Methods:

SIOP 93-01 protocol was used to study nine patients of sBWT in a single center and followed up over a period from 2 to 5 years.

Statistical Analysis Used:

Unpaired t-test and Mann–Whitney U-test were used for analysis.

Results:

Of nine patients, six were included in the study as three patients lost to follow-up. Among the six patients, there were four girls and two boys with a median age of 2 years. Mean regression in the size of tumor was 87% in four out of six patients. Tumor with unfavorable histology showed 32% response (ratio of favorable: unfavorable histology 2:1). Event-free survival rate was 81.3% and overall survival was 90% over 2–5 years. Recurrence was seen in two patients of whom one had Denys–Drash syndrome. Mean DTPA glomerular filtration rate was 91.4/ml/min/1.73 m² preoperatively and that of 3 months after completion of treatment was 84/ml/min/1.73 m². Health-related quality of life (HRQOL) using Pediatric Quality of Life Inventory and Lansky Play Performance Scale revealed significant improvement results of all functioning domains such as physical, social, emotional, and school subscales with P < 0.05 and performance scale (P < 0.04).

Conclusions:

We suggest SIOP protocol for sBWT and bilateral nephron-sparing surgery in two stages. However, long-term follow-up is required to assess the ultimate renal function outcome. HRQOL is an essential guide in improving the conditions of pediatric cancer survivors.

Family Functioning and Depressive Symptoms in Adolescent and Young Adult Cancer Survivors and Their Families: A Dyadic Analytic Approach

Background

To examine dyadic relationships between depressive symptoms and family functioning in families of pediatric cancer survivors. Methods Sixty-four adolescent and young adult (AYA) cancer survivors and their caregivers self-reported on depressive symptoms and family functioning. Multilevel modeling analyses were used to test actor–partner interdependence models.

Results

Significant actor effects of depressive symptoms on domains of family functioning were found for AYAs and their caregivers. Only caregivers’ depressive symptoms exerted a significant effect on AYAs’ report of family cohesion, indicating the presence of significant partner effects for AYAs.

Conclusions

AYAs’ and caregivers’ depressive symptoms are related to poorer family functioning. Caregivers’ perceptions of depressive symptoms relate not only to their own perceptions of family functioning but also to that of their children. These findings begin to map the complex relationships that exist between AYAs and their caregivers and elucidate some of the mechanisms through which caregiver-related variables affect AYA outcomes.

Quality of life in pediatric cancer survivors: contributions of parental distress and psychosocial family risk

Background

Pediatric survivors of childhood cancer are at increased risk of poor quality of life and social-emotional outcomes following treatment. The relationship between parent psychological distress and child adjustment in pediatric cancer survivors has been well established. However, limited research has examined the factors that may buffer this association. The current study examined the associations between psychosocial family risk factors, parental psychological distress, and health-related quality of life (hrql) in pediatric cancer survivors.

Methods

Fifty-two pediatric cancer survivors (34 males, 18 females, mean age = 11.92) and their parents were recruited from a long-term cancer survivor clinic. Children and their parents who consented to participate completed the Pediatric Quality of Life Inventory 4.0. Parents completed a demographic information form, the Psychosocial Assessment Tool (pat 2.0) and the Brief Symptom Inventory (bsi). The Intensity of Treatment Rating (itr-3) was evaluated by the research team.

Results

Multiple regression analyses revealed that parental psychological distress negatively predicted parent-reported hrql, while treatment intensity, gender, and psychosocial risk negatively predicted parent and child-reported hrql. Psychosocial risk moderated the association between parent psychological distress and parent-reported child hrql (p = 0.03), whereby parents with high psychological distress but low levels of psychosocial risk reported their children to have higher hrql.

Conclusion

Low levels of family psychosocial risk buffer the impact of parent psychological distress on child hrql in pediatric cancer survivors. The findings highlight the importance of identifying parents and families with at-risk psychological distress and psychosocial risk in order to provide targeted support interventions to mitigate the impact on hrql.

Could we use parent report as a valid proxy of child report on anxiety, depression, and distress? A systematic investigation of father-mother-child triads in children successfully treated for leukemia

BACKGROUND

Systematic assessment of emotional distress is recommended in after care. Yet, it is unclear if parent report may be used as a proxy of child report. The aim of this study was to assess agreements and differences and explore possible moderators of disagreement between child and parent ratings.

METHODS

Sixty-two young survivors treated for acute lymphoblastic leukemia (9-18 years) and both parents responded to the Beck Youth Inventory (anxiety and depression) and the distress rating scale on the child's status. Parents completed the Brief Symptom Inventory-18 on their own psychological status. Systematic analyses of agreement and differences were performed.

RESULTS

Mother-child and father-child agreements were fair on anxiety, depression, and distress (median intraclass correlation coefficient = 0.37). Differences between parents and children were medium sized (median d = 0.55) with parents giving higher scores than their children on anxiety, depression, and distress. Mothers reported distress more frequently than fathers (39 vs. 17%) when children reported none. The child being female and lower parental income were associated with lower agreement in fathers when rating child distress. Higher levels of parental psychological symptoms were consistently associated with lower agreement.

CONCLUSIONS

Parent-child differences when rating adolescent survivors' difficulties may be more important than previously thought. Parent report probably cannot be considered as a valid proxy of older child report on such internalized domains as anxiety, depression, or distress in the after-care clinic. Parents' report is also likely to be influenced by their own mood, a factor that should be corrected for when using their report.

Computerized Adaptive Testing in Pediatric Brain Tumor Clinics

CONTEXT

Monitoring of health-related quality of life and symptoms of patients with brain tumors is needed yet not always feasible. This is partially due to lack of brief-yet-precise assessments with minimal administration burden that are easily incorporated into clinics. Dynamic computerized adaptive testing (CAT) or static fixed-length short forms, derived from psychometrically sound item banks, are designed to fill this void.

OBJECTIVE

This study evaluated the comparability of scores obtained from CATs and short forms.

METHODS

Patients (ages 7-22 years) were recruited from brain tumor clinics and completed Patient-Reported Outcome Measurement Information System CATs and short forms (Fatigue, Mobility, Upper Extremity, Depressive Symptoms, Anxiety, and Peer Relationships). Pearson correlations, paired t-tests, and Cohen's d were used to evaluate the relationship, significant differences, and the magnitude of the difference between these two scores, respectively.

RESULTS

Data from 161 patients with brain tumors were analyzed. Patients completed each CAT within 2 minutes. Scores obtained from CATs and short forms were highly correlated (r = 0.95-0.98). Significantly different CAT vs. short-form scores were found on 4 (of 6) domains yet with negligible effect sizes (|d| < 0.09). These relationships varied across patients with different levels of reported symptoms, with the strongest association at the worst or best symptom scores.

CONCLUSIONS

This study demonstrated the comparability of scores from CATs and short forms. Yet the agreement between these two varied across degrees of symptom severity which was a result of the ceiling effects of static short forms. We recommend CATs to enable individualized assessment for longitudinal monitoring.

A prospective follow-up of quality of life, depression, and anxiety in children with lymphoma and solid tumors

Background/aim: The aim of this study was the determination and prospective follow-up of quality of life, depression, and anxiety in pediatric patients with cancer under chemotherapy, as well as the evaluation of related factors. Materials and methods: Fifty newly diagnosed pediatric cancer patients and their parents were prospectively monitored before, during, and after therapy, and tests were used. Results: Significantly lower quality of life scores were recorded during treatment, in the group with CNS tumors, in the group receiving chemotherapy plus radiotherapy plus surgery, in the inpatient-only treatment group, in the group receiving treatment for longer than 6 months, and in the group of patients whose diagnosis was delayed for more than 3 months. Total quality of life scores for children and their parents were 82.95 ± 14.59 vs. 83.61 ± 14.60 before, 54.69 ± 16.51 vs. 55.78 ± 16.05 during, and 83.88 ± 12.44 vs. 84.19 ± 13.22 at the end of treatment (P < 0.05). Anxiety and depression scores were significantly higher during treatment, in patients whose diagnoses were delayed for more than 3 months, and among inpatients. Conclusion: The quality of life of a majority of our patients was severely affected, and depression and anxiety were more frequently seen especially during treatment.

Developing the Evidence Base in Pediatric Oncology Nursing Practice for Promoting Health-Related Quality of Life in Pediatric Oncology Patients

Research has shown that self-esteem and hopefulness are positively related among female childhood cancer survivors (CCS) and contribute to their health-related quality of life (HRQOL). HRQOL remains a significant outcome of treatment for CCS. This study examined the relationships among self-esteem, hopefulness, and HRQOL in young adult female CCS to inform the development of evidence-based practice guidelines for pediatric oncology nursing practice. An online survey was conducted with a sample of young adult female CCS from 58 treatment centers across the United States at 4 time points: at baseline and at 6 weeks, 3 months, and 6 months after initial measurement time. The relationships between self-esteem, hopefulness, and HRQOL were statistically significant (Time 1, P = .05; Times 2, 3, and 4, P = .01) across all measurement times. These findings identify hopefulness and self-esteem as determinants of HRQOL and suggest that caring practices among pediatric oncology nurses that support psychosocial adjustment through promoting self-esteem and hopefulness have the potential to support HRQOL among young adult female CCS. These outcomes support the development of evidence-based practice guidelines to influence HRQOL outcomes among these survivors.

A systematic review on factors and consequences of parental distress as related to childhood cancer

The literature including correlates of parental distress as related to childhood cancer is abundant. It is important to identify predictive factors and outcomes of this distress in parents. The objective of this review was to update previous syntheses on factors of distress and to identify outcomes of parents' distress in the recent literature (2007-2012). We performed a systematic review to identify all quantitative studies including measures of parental distress and associated factors during the study period. We found 56 eligible studies, of which 43 had a Low risk of bias (Cochrane guidelines). Forty-two reports included potential predictive factors. Significant relationships were found with clinical history of the child, sex of the parent, coping response and personal resources, pre-diagnosis family functioning, but not education/income or marital status. Twenty-five reports studied potential consequences of distress and focused on psychological adjustment in parents and children. Compared to past periods, a higher proportion of studies included fathers. Measures used to evaluate distress were also more homogeneous in certain domains of distress. This review underscores the need for appropriate methods for selecting participants and reporting results in future studies. Appropriate methods should be used to demonstrate causality between factors/consequences and distress.

Acceptance and commitment therapy in youth with neurofibromatosis type 1 (NF1) and chronic pain and their parents: A pilot study of feasibility and preliminary efficacy

Neurofibromatosis type 1 (NF1) is an autosomal dominant genetic disorder affecting about 1 in 3,500 individuals. Chronic pain is commonly reported among individuals with NF1 and plexiform neurofibroma tumors (PNs). Acceptance and Commitment Therapy (ACT), an empirically supported method for addressing chronic pain, helps individuals re-focus on valued relationships and activities. This pilot study investigated the feasibility and preliminary efficacy of a brief ACT workshop in the NF1 population. Eligible participants included adolescents and young adults (AYA; 12-21 years) with NF1 and chronic pain that interfered with daily functioning and their parents. Patients and parents completed baseline measures of pain interference, pain intensity, functional disability, pain acceptance, depression, and anxiety. Then, AYA and parents participated separately in a 2-day small-group ACT workshop. A telephone booster session occurred 1 month post-intervention. Three-month post-treatment measures were completed by mail. Ten adolescents (4 males; M age = 16.9 years) and seven parents provided baseline and 3-month data. Mean satisfaction with the study was moderate to high (3.9 for patients and 4.6 for parents on a 1-5 scales). Patients and parents reported significant declines in patients' pain interference at 3 months post-treatment. Patient-reported pain intensity significantly declined from baseline to 3 months. Parents reported marginally greater acceptance of their child's pain. No changes emerged in functional ability or mood. Preliminary findings suggest that a brief ACT group intervention is feasible and may help AYA with NF1 and PNs cope with their chronic pain, although larger randomized studies are needed to confirm treatment efficacy. © 2016 Wiley Periodicals, Inc.

Do environmental barriers affect the parent-reported quality of life of children and adolescents with cerebral palsy?

Physical, social, and attitudinal environment may affect the quality of life (QoL) of children and adolescents with cerebral palsy (CP). Participants in this study included parents of 206 children and adolescents with CP (55.8% males) aged 8-18 years (M=11.96, SD=3). Distribution according to the Gross Motor Function Classification System (GMFCS) was 24.3% level I, 18% level II, 18% level III, 12.6% level IV, and 27.2 level V. Environmental barriers were assessed with the Spanish version of the European Child Environment Questionnaire (ECEQ), and QoL was assessed with the KIDSCREEN parents' version. The results of the correlation analysis revealed that GMFCS level, IQ, and type of schooling are significantly correlated with QoL. Barriers were also associated with QoL. A series of hierarchical regression analyses indicated that, after controlling for the effect of child and parent's variables, barriers at home and at school significantly contribute to QoL. These findings underscore the importance of providing interventions to produce environmental changes that contribute to the improvement of QoL.

Post-thrombotic syndrome after central venous catheter removal in childhood cancer survivors: A prospective cohort study

BACKGROUND

Although the use of central venous catheters (CVCs) has greatly improved the quality of care of children with cancer, these catheters increase the risk of deep vein thrombosis (DVT) and the potential long-term complication of post-thrombotic syndrome (PTS). We aimed to study PTS post-CVC removal using physical, functional and health related quality of life (HRQoL) domains in childhood cancer and bone marrow transplantation (BMT) survivors.

PROCEDURE

We conducted a prospective study in a cohort of childhood cancer and BMT survivors post-CVC use. Participants were evaluated for PTS with the Modified Villalta Score (MVS) and the Manco-Johnson Instrument (MJI). HRQoL was assessed using the PedsQL™ questionnaire.

RESULTS

A total of 158 children were enrolled at a median of 41 (4-149) months from CVC removal. Signs and symptoms of PTS were present in 34% (95% confidence interval [CI] 27-43%) (MVS criteria) and 30.5% (95% CI 23.1-37.8%) (MJI criteria). Diagnosis of PTS was associated with history of CVC occlusion, history of CVC-related DVT and the use of ≥2 CVCs. The presence of signs and symptoms of PTS was a predictor for low HRQoL tested by the PedsQL™ Total Scale scores and Physical Health Summary scores.

CONCLUSIONS

PTS post-CVC removal in pediatric cancer survivors is not a rare event. The association between PTS and the history of CVC occlusion confirms earlier findings, and suggests that CVC occlusion may indicate asymptomatic DVT. PTS is also associated with lower HRQoL scores highlighting the need to study preventive measures, especially for high risk groups.

Multidisciplinary pediatric brain tumor clinics: the key to successful treatment?

Tumors of the CNS are the most common solid tumors diagnosed in childhood. As technology and research in cancer care are advancing, more specialties are involved in the diagnosis, treatment and follow-up of children with brain tumors. Multidisciplinary clinics have become the standard of care for cancer care throughout the USA, and specialty clinics focused on particular cancer types are gaining attention in improving the patient outcomes and satisfaction. We will discuss the role of multidisciplinary clinics, in an attempt to create preliminary guidelines on establishing and maintaining a multidisciplinary brain tumor clinic in order to optimize the care of the patients and their families.

Parental mental health moderates the efficacy of exercise training on health-related quality of life in adolescents with congenital heart disease

To evaluate the moderating influence of parental variables on changes in health-related quality of life (HRQoL) in adolescents with Tetralogy of Fallot (ToF) or a Fontan circulation after participation in standardized exercise training. A multicenter randomized controlled trail in which 56 patients, aged 10-15, were randomly allocated (stratified by age, gender, and congenital heart disease) to a 12-week period with either: (a) 3 times per week standardized exercise training or (b) care-as-usual (randomization ratio 2:1). Adolescents and their parents filled in online questionnaires at baseline and at 12-week follow-up. In this randomized controlled trail, primary analyses involved influence of parental mental health and parental social support for exercise on changes in the TNO/AZL Child Quality of Life Questionnaire Child Form at follow-up. Secondary analyses concerned comparing levels of parental characteristics with normative data. Compared with controls, adolescents in the exercise group reported a decrease in social functioning when their parents had more anxiety/insomnia or severe depression themselves. Adolescents also reported a decrease in social functioning when their parents showed poorer overall mental health themselves. Parents reported comparable or even better mental health compared with normative data. The effect of a standardized exercise program on HRQoL changes in adolescents with ToF or a Fontan circulation is moderated by parental mental health, more specifically by parental anxiety/insomnia and severe depression. The trial registration number of this article is NTR2731 ( www.trialregister.nl ).

Health-related quality of life in paediatric asthma: Children's and parents' perspectives

This study aimed to describe the quality of life of a group of Portuguese children with asthma, to explore the association between health-related quality of life (HRQL), asthma severity, child's characteristics and parental psychopathology. Additionally, the concordance between the children's HRQL self-report and the parents' HRQL proxy was assessed. Fifty children with asthma (7-13 years) and their primary caregiver participated in the study by filling out the DISABKIDS-37 and other self-report questionnaires. Results for the DISABKIDS-37 supported a good internal consistency and associations between the facets and the global score, in the two versions of the questionnaire. Children and their caregivers scored the child's HRQL positively. Parents of children with an asthma diagnosis for a longer period reported better HRQL. The distribution of the HRQL scores in the child's version showed differences across categories of subjective severity rated by children and across categories of asthma control assessed by the physician. The group with uncontrolled asthma obtained lower HRQL scores than the other groups. There was a lack of convergence between self-report and parent's report of HRQL, with the exception of the physical limitation facet. Asthma severity assessed by the child and parental psychopathology explained 28% of the variance in the children's self-rated HRQL. Findings reinforce that children and caregivers' reports are complementary to each other and support the recommendation to use both information sources.

Impact of children's feeding/swallowing problems: validation of a new caregiver instrument

The impact of caring for children with deglutition disorders is poorly understood and tools to measure the unique concerns of these caregivers are lacking. The aims of this investigation were to develop and validate The Feeding/Swallowing Impact Survey (FS-IS) as an instrument designed to measure and improve understanding of caregiver issues. Demographic, economic, and dysphagic data were provided by the primary caregivers of 164 children (median age: 14 months, male: 78, female: 86) presenting for initial outpatient feeding/swallowing evaluations. Caregivers completed the PEDS-QL™ Family Impact Module (PEDS-QL™ FIM) and the FS-IS. A principal component analysis was conducted on the FS-IS to identify appropriate subscales. Concurrent validity was assessed by examining correlations between the FS-IS and PEDS-QL™ FIM. Caring for children with feeding/swallowing problems adversely impacted the Health-Related Quality of Life (HRQoL) of their caregivers. The FS-IS had a strong 3-factor solution to indicate 3 subscales: Daily Activities, Worry, and Feeding Difficulties. All three subscales and total score of the FS-IS correlated with PEDS-QL™ FIM. The FS-IS was validated as an instrument that may help clinicians detect specific factors that influence caregiver HRQoL, identify caregivers who might benefit from additional support, and ultimately improve the care of their children with feeding/swallowing disorders.

Health-related quality of life of adolescent and young adult survivors of childhood brain tumors

OBJECTIVE

Our aim was to expand research on predictors of health-related quality of life (HRQOL) for adolescent and young adult survivors of childhood brain tumors who are not living independently by evaluating the mediating role of family functioning in the association of disease severity/treatment late effects with survivor self-report and caregiver-proxy report of physical and emotional HRQOL.

METHODS

Mothers (N = 186) and their survivors living at home (N = 126) completed self-report and caregiver-proxy report of physical and emotional HRQOL. Mothers completed family functioning measures of general family functioning, caregiving demands, and caregiver distress. Medical file review and caregiver report were used to evaluate disease severity/treatment late effects.

RESULTS

Using structural equation models, family functioning was adjusted for sociodemographic factors. Disease severity/treatment late effects had significant direct effects on self-report and caregiver-proxy report of physical and emotional HRQOL. Family functioning had a significant direct effect on caregiver-proxy report of physical and emotional HRQOL, but these findings were not confirmed for self-report HRQOL. Model-fit indices suggested good fit of the models, but the mediation effect of family functioning was not supported.

CONCLUSIONS

Disease severity/treatment late effects explained self-report and caregiver-proxy report of physical and emotional HRQOL for these adolescent and young adult survivors of childhood brain tumors. Family functioning was implicated as an important factor for caregiver-proxy report only. To enhance physical and emotional HRQOL, findings underscore the importance of coordinated, multidisciplinary follow-up care for the survivors who are not living independently and their families to address treatment late effects and support family management.

Temperament, personality, and quality of life in pediatric cancer patients

OBJECTIVE

The developmental psychology literature shows that children with higher levels of effortful control (EC) and ego-resilience (ER) display greater social competence and better emotional adjustment. This study examined whether these dispositional attributes contribute to positive quality of life (QOL) in pediatric cancer patients.

METHOD

Participants were 103 pediatric cancer patients (and their parents) who were part of a larger parent study. At study entry, parents reported their own anxiety and depression and their children's EC and ER. At 3-month follow-up, parents reported children's QOL.

RESULTS

ER was positively correlated with children's QOL. EC showed a positive indirect effect on QOL through ER. Inclusion of potential correlates of pediatric QOL (e.g., parent neuroticism) did not change these relationships.

CONCLUSIONS

Temperament and personality play significant roles in pediatric cancer patients' QOL. Assessing dispositional attributes early in treatment may help identify children at risk for poor QOL during and after treatment.
