Factors affecting quality of life in Taiwanese survivors of childhood cancer

Health related quality of life in pediatric hematological malignancies patients and survivors: A meta-analysis of comparative studies

BACKGROUND

Pediatric patients with hematologic malignancies (HM) and survivors are at high risk for numerous negative effects including decreased health-related quality of life (HRQOL). In order to understand the association between HM and QOL, we conducted this meta-analysis to systematically compare QOL between pediatric HM patients and survivors and controls.

METHOD

The PubMed, EMBASE, Web of Science and the Cochrane Library databases were systematically searched. Data were analyzed using the random-effects model.

RESULTS

Of 6586 unique articles identified, 30 were included in this meta-analysis. Studies described 12 different HRQOL tools. Different QOL measures varied in their association with quality of life. When compared with Non-HM group, the Pediatric Quality of Life Inventory (PedsQL) has a moderate effect size (standard mean difference, SMD = 0.50, 95% CI: 0.32, 0.68; P < 0.001). When compared with health controls, it has a large effect size (SMD = -1.00, 95% CI: -1.47, -0.53; P < 0.001). In addition, Health utilities index mark (HUI), and the Pediatric Oncology Quality of Life Scale (POQOLS) have a large (SMD = -0.81, 95% CI: -1.29, -0.33; P = 0.001) and a small (SMD = -0.10, 95% CI: -0.42, 0.22; P = 0.534) effect sizes when comparing overall controls.

CONCLUSION

Pediatric HM patients and survivors had lower QOL compared with healthy controls and higher QOL compared with Non-HM controls in most domains. Considering the negative impact of poor QOL on daily life and functional outcomes, future research should focus on proposing effective measures to improve QOL of this population.

Resilience and Quality of Life in People with Mental Illness: A Systematic Review and Meta-Analysis

Purpose

Resilience is viewed as an individual' positive adaptation and experiences of adversity. The maintenance and recovery of mental health in people with mental disorder is considered a sign of coping with adverse conditions. The purpose of the present meta-analysis was to examine the association between resilience and quality of life in individuals with mental disorders.

Methods

Studies were included if research reported measures of association with resilience, as assessed using self-reported resilience scale and quality of life. A systematic literature search was conducted in PubMed and PsycINFO.

Results

Eight studies involving a total of 1439 patients were included in the meta-analysis. Assuming a random-effects model, the weighted mean Pearson correlation between resilience and quality of life was r = 0.551 (95% confidence interval [0.370; 0.691], p < 0.001). This association was moderate, although the heterogeneity among individual effect sizes was substantial (I² = 93.35%).

Conclusion

Despite substantial heterogeneity across included studies, the findings suggest a strong association between resilience and quality of life in people with mental disorders. In clinical practice, the promotion of resilience is important to enhance the quality of life among people with mental illness.

An investigation of cultural influences in survivors of paediatric cancer: a systematic review protocol

INTRODUCTION

Paediatric cancer affects children and families from diverse backgrounds. However, there is a limited understanding of how diversity/cultural factors play a role, especially in survivorship. This protocol outlines a systematic review on the cultural influences in survivors of childhood cancer.

METHODS AND ANALYSIS

This protocol is reported based on the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA) guidelines checklist and is registered with PROSPERO. EMBASE, MEDLINE and PsycINFO are searched. Eligibility criteria include original research studies published in English, and an assessment of culture on survivors of childhood cancer. Search terms are developed with a medical librarian. Primary objective will be to describe culture (ethnic and population groups, migration status, acculturation, cultural characteristics) in survivors of paediatric cancer and study characteristics and methods. Secondary objective will be to identify the role of culture in outcomes of survivors of paediatric cancer. Data extraction will include participant characteristics such as the number of participants and/or controls, sex, age at diagnosis. Extraction will also include analytical approaches, type of cultural variables (predictor, moderator, mediator, outcome) and effect measures.

ETHICS AND DISSEMINATION

Ethical approval was not required for this systematic review. Results from this systematic review will be disseminated in line with PRISMA guidelines through peer-reviewed publications and conference presentations. Findings will also be shared with our target communities, including survivors of childhood cancer and their families, through the creation of lay summaries and/or educational workshops in the community. Knowledge gathered from this review may help to identify gaps in knowledge and directions for future research. They may also inform the development of clinical recommendations for healthcare providers of survivors of childhood cancer.

A measure for assessment of beneficial and harmful fortitude: development and initial validation of the sisu scale

Sisu is a Finnish cultural concept that denotes determination and resoluteness in the face of adversity. We propose that sisu will supplement the English-language based research on mental fortitude traits. Sisu has not been the focus of systematic research until very recently. We created a new questionnaire measuring sisu (the Sisu Scale), sought to validate the sisu construct and its sub-factor structure as postulated in a recent qualitative study. We investigated associations of sisu with other measures of mental fortitude and well-being. More generally we aimed to enrichen the cross-cultural understanding of human experience of overcoming adversity across life's challenges.

We describe and validate a questionnaire that effectively measures both beneficial and harmful sisu, each comprising three sub-factors. Beneficial sisu was associated with other measures of fortitude, but less with personality dimensions. We also confirmed the existence of an independent harmful sisu factor. Beneficial sisu was associated with higher well-being and lower depressive symptoms, and harmful sisu with lower well-being and higher levels of general stress, work stress and depressive symptoms. Together the two factors were superior compared to pre-existing measures when predicting well-being-related variables. Results suggest that the new Sisu Scale we developed may provide a valuable addition to research on mental fortitude, resilience and their consequences for well-being.

Social adjustment across the lifespan in survivors of pediatric acute lymphoblastic leukemia (ALL): a systematic review

PURPOSE

The objectives of this review were to (1) summarize studies that described social adjustment in survivors of pediatric ALL across the lifespan, (2) summarize social adjustment outcomes reported across studies, and (3) examine associations between social adjustment and disease/treatment- and non-treatment-related factors.

METHODS

Searched databases included EMBASE (Ovid), MEDLINE (Ovid), PsycINFO (EBSCO Information Services), and Web of Science (Thomson Reuters). Eligible studies included: (1) original research; (2) published in English; (3) a diagnosis of cancer between 0 and 21 years; (4) survivors at least 5 years from diagnosis and/or 2 years from therapy completion; and (5) quantitative assessment of social adjustment.

RESULTS

The literature search yielded 3698 articles of which 43 were included in the final review. Risk of bias was assessed using domains adapted from the Cochrane risk-of-bias tool. Quality of evidence was evaluated following the Grading of Recommendations Assessment Development and Evaluation (GRADE) criteria. There was some evidence that school-aged and adolescent/young adult survivors experienced worse social adjustment compared to controls. There was some evidence suggesting cranial radiation therapy (CRT) is associated with social adjustment difficulties among young adult survivors. Inconsistent evidence was found for relapse, age at diagnosis and study, sex, and late effects in relation to social adjustment.

CONCLUSION

Survivors of pediatric ALL were at higher risk of social adjustment difficulties compared to controls. However, evidence for treatment and non-treatment risk and resilience factors require stronger evidence.

IMPLICATIONS FOR CANCER SURVIVORS

Information on modifiable factors that modulate social adjustment may influence targets of intervention and follow-up guidelines.

Factors Influencing Resilience among Korean adolescents and young adult survivors of childhood cancer

PURPOSE

The number of childhood cancer survivors has been steadily increasing because of improved cancer treatment outcomes. We aimed to examine the level of cancer stigma, coping, spirituality, hope, family communication, social support and resilience in adolescent and adult childhood cancer survivors and identify factors associated with resilience.

METHOD

This study is a descriptive survey conducted on 139 childhood cancer survivors aged 15-29 years who had been diagnosed with cancer prior to the age of 19 years at a general hospital in Seoul. The questionnaire consisted of the Cancer Stigma Scale, Jalowiec Coping Scale, Functional Assessment of Chronic-Illness Therapy-Spirituality (FACIT-Sp), Hearth Hope Index (HHI), Parent-Adolescent Communication Inventory (PACI), Multidimensional Scale of Perceived Social Support (MSPSS), and Haase Resilience in Illness Scale (HARS). Collected data were analyzed using multiple linear regression analysis with SPSS 23.0.

RESULTS

Resilience positively correlated with courageous coping, spirituality, hope, family communication and social support, and negatively correlated with cancer stigma and defensive coping. Regression analyses revealed that courageous coping (β = 0.303, p < .001), hope (β = 0.317, p = .001), and solid tumor diagnosis (β = -0.144, p = .012) were significantly predictive of resilience among childhood cancer survivors, and these factors explained 65.2% of the variance.

CONCLUSIONS

Resilience among childhood cancer survivors was higher with increasing courageous coping and hope and lower with solid tumors. These results suggest that coping and hope management should be included in the strategies to enhance the resilience of AYA cancer survivors.

Friendship in Adolescents and Young Adults With Experience of Cancer: A Dimensional Analysis

BACKGROUND

Friendship is a complex social phenomenon important to human development, emotional health, and socialization. While making and maintaining peer friends are an emphasized task of adolescent and young adult development, the multidimensional experience of friendship is incompletely defined, particularly in the context of adolescents and young adults with cancer.

OBJECTIVE

The aim of this study was to investigate the nature of friendship more deeply and completely by breaking down and then rebuilding meaning in this phenomenon.

METHODS

The author searched 8 databases for relevant literature and conducted a dimensional analysis of the textual data from articles found in database searches and theoretical sampling. Dimensional analysis was an inductive process of determining all the components and attributes of the friendship concept. The author broke down and built up the meaningful units of friendship until a story of friendship in adolescents and young adults with experience of cancer emerged.

RESULTS

Data from 80 empirical and theoretical articles published from 2013 to 2018 formed the literature base for this dimensional analysis.

CONCLUSIONS

An explanatory matrix built from the perspective of "Time Marking" reveals contexts, conditions, processes, and consequences that together provide an explanation of the nature of friendship in this population.

IMPLICATIONS FOR PRACTICE

This concept analysis, combined with the limitations of this inquiry, impels future empirical and theoretical research and implies preliminary clinical implications. In particular, the understanding of friendship as conceptually distinct from social support and the experience of friendships in narrative time suggest a need to reconceptualize supportive care services for adolescents and young adults who experience cancer.

[Examining the Psychological Resilience of Adolescents with Leukemia: A Comparative Study]

AIM

This descriptive and comparative research was conducted to determine the level of psychological resilience of adolescents diagnosed with leukemia.

METHOD

The sample research group comprised of eighty adolescents in the 15-18 age group who have leukemia in pediatric hematology outpatient clinics. The sample comparison group comprised of eighty healthy adolescents in the 15-18 age group who were students from years 9, 10, 11, and 12th in a high school. Data was collected using a socio-demographic questionnaire and the California Healthy Kids Survey Resilience and Youth Development Module High School Questionnaire form. The Mann-Whitney U Test, Kruskal Wallis variance analysis, homogeneity test (Levene), and Ki kare Test were used to evaluate the data.

RESULTS

It was seen that there were no significant differences between the psychological resilience of adolescents with leukemia and healthy adolescents (p>0.05) Females were observed to have higher levels of psychological resilience than males in the research group. A lower level of psychological resilience was identified in adolescents from the research group who did not receive psychological support during the illness compared with those who received psychological support (p<0.05). The sub-factor point average of caring relationships and high expectations at school were higher in the research group, whereas the sub-factor point average of goals and aspirations were higher in the healthy adolescents (p<0.05).

CONCLUSION

As a result, it was suggested that preventive mental health services should be planned and implemented to develop resilience levels and protective relationships provided by the school, friends, family and society should be supported.

Assessing Self-concept as a Mediator Between Anger and Resilience in Adolescents With Cancer in Taiwan

BACKGROUND

Anger is considered a common method used by patients to relieve emotional frustrations. However, this emotional response is not a common research focus for adolescents with cancer.

OBJECTIVE

The aim of this study was to determine whether self-concept mediated the relationship between anger and resilience for adolescent patients currently being treated for cancer.

METHODS

A cross-sectional study of 40 adolescents with cancer was conducted. The instruments included the Chinese Beck Self-Concept Inventory, the Chinese Beck Anger Inventory, and the Chinese Resilience Scale. Mediation analysis was also conducted.

RESULTS

The results indicate that (1) variations in anger significantly account for 6.86% of observed variations in self-concept, (2) variations in self-concept significantly account for 52.83% of observed variations in resilience, (3) variations in anger significantly account for 10.96% of observed variations in resilience, and (4) when paths in conditions 1 and 2 were controlled, variations in anger through self-concept significantly account for 54.04% of observed variations in resilience, and variations in anger did not significantly account for observed variations in resilience.

CONCLUSIONS

Gender and age might affect anger control. Despite worse physical functioning and an impacted appearance, participants had normative-to-positive self-concept levels, suggesting that their self-concept might not be affected by cancer. Self-concept might play a mediating role between anger and resilience, thus helping to bridge this knowledge gap.

IMPLICATIONS FOR PRACTICE

The current gap in knowledge regarding the mediating relationship necessitates the implementation of a large-scale study designed to verify the mediating role of self-concept between anger and resilience.

Children's and Parents' Conceptualization of Quality of Life in Children With Brain Tumors: A Meta-Ethnographic Exploration

The concept of quality of life (QoL) is used in consultations to plan the care and treatment of children and young people (CYP) with brain tumors (BTs). The way in which CYP, their parents, and their health care professionals (HCP) each understand the term has not been adequately investigated. This study aimed to review the current qualitative research on CYP, parents' and clinicians' concepts of QoL for CYP with BTs using meta-ethnography. Six studies were found, which reflected on the concept of QoL in CYP with BTs; all explored the CYP's perspective and one study also touched upon parents' concept. A conceptual model is presented. Normalcy (a "new normal") was found to be the key element in the concept. This study calls for a conception of QoL, which foregrounds normalcy over the more common health-related quality of life (HRQoL) and the need to understand the concept from all perspectives and accommodate change over time.

Affiliate stigma and its association with quality of life among caregivers of relatives with mental illness in Singapore

Affiliated stigma often refers to internalized stigma among family members of stigmatized individuals. This study aimed to investigate the relationship between affiliate stigma and quality of life (QOL) among primary caregivers of individuals with mental illness undergoing treatment at the Institute of Mental Health, Singapore. Three hundred and fifty caregivers were recruited for the study. The World Health Organization Quality of Life questionnaire (WHOQOL-BREF) and Family Stigma Scale (FSS) were administered to the primary caregivers of patients with mental illness. Multiple linear regression analyses were conducted to investigate the association of affiliate stigma with QOL. A high proportion of caregivers of individuals with mental illness experience affiliate stigma in Singapore. All four QOL domains were significantly associated with affiliate stigma. These findings entail that it is imperative to improve public's perception of those with mental illness to reduce stigmatization and thus improve caregiver's QOL.

Unemployment Following Childhood Cancer

BACKGROUND

Childhood cancer survivors are at risk of physical and mental long-term sequelae that may interfere with their employment situation in adulthood. We updated a systematic review from 2006 and assessed unemployment in adult childhood cancer survivors compared to the general population, and its predictors.

METHODS

Systematic literature searches for articles published between February 2006 and August 2016 were performed in CINAHL, EMBASE, PubMed, PsycINFO, and SocINDEX. We extracted unemployment rates in studies with and without population controls (controlled /uncontrolled studies). Unemployment in controlled studies was evaluated using a meta-analytic approach.

RESULTS

We included 56 studies, of which 27 were controlled studies. Approximately one in six survivors was unemployed. The overall meta-analysis of controlled studies showed that survivors were more likely to be unemployed than controls (Odds Ratio [OR] = 1.48, 95% confidence interval [CI]: [1.14; 1.93]). Elevated odds were found in survivors in the US and Canada (OR = 1.86, 95% CI: [1.26; 2.75]), as well as in Europe (OR = 1.39, 95% CI: [0.97; 1.97]). Survivors of brain tumors in particular were more likely to be unemployed (OR = 4.62, 95% CI: [2.56; 8.31]). Narrative synthesis across all included studies revealed younger age at study and diagnosis, female sex, radiotherapy, and physical late effects as further predictors of unemployment.

CONCLUSION

Childhood cancer survivors are at considerable risk of unemployment in adulthood. They may benefit from psycho-social care services along the cancer trajectory to support labor market integration.

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.

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.

Systematic review and meta-analysis of health-related quality of life in pediatric CNS tumor survivors

BACKGROUND

Pediatric central nervous system (CNS) tumor survivors are at high risk for numerous late effects including decreased health-related quality of life (HRQOL). Our objective was to summarize studies describing HRQOL in pediatric CNS tumor survivors and compare HRQOL outcomes in studies that included a comparison group.

PROCEDURE

EMBASE, MEDLINE, and PsychINFO were used to identify relevant articles published until August, 2016. Eligible studies reported outcomes for pediatric CNS tumor survivors diagnosed before age 21, at least 5 years from diagnosis and/or 2 years off therapy and used a standardized measure of HRQOL. All data were abstracted by two reviewers. Random-effects meta-analyses were performed using Review Manager 5.0.

RESULTS

Of 1,912 unique articles identified, 74 were included in this review. Papers described 29 different HRQOL tools. Meta-analyses compared pediatric CNS tumor survivors to healthy comparisons and other pediatric cancer survivors separately. HRQOL was significantly lower for CNS (n = 797) than healthy comparisons (n = 1,397) (mean difference = -0.54, 95% confidence interval [CI] = -0.72 to -0.35, P < 0.001, I² = 35%). HRQOL was also significantly lower for CNS (n = 244) than non-CNS survivors (n = 414) (mean difference = -0.56, 95% CI = -0.73 to -0.38, P < 0.00001, I² = 0%).

CONCLUSIONS

Pediatric CNS tumor survivors experience worse HRQOL than healthy comparisons and non-CNS cancer survivors. Future HRQOL work should be longitudinal, and/or multisite studies that examine HRQOL by diagnosis and treatment modalities.

Effects of resilience on quality of life in patients with bipolar disorder

BACKGROUND

Few studies have examined the effects of resilience on quality of life (QOL) in patients with bipolar disorder (BD). Therefore, this study investigated the association between resilience and QOL in patients with BD and compared it to the relationship between resilience and QOL in healthy individuals.

METHODS

Participants were 68 euthymic patients with BD and 68 age-, sex-, and length of education-matched controls. Sociodemographic characteristics and clinical variables of the two groups were obtained using face-to-face interviews, and all participants completed the Connor-Davidson Resilience Scale, the World Health Organization QOL-Brief Form.

RESULTS

The QOL of the BD group was significantly impaired compared with that of the controls. Degree of resilience, number of depressive episodes, Clinical Global Impression scores, degree of impulsivity, and length of education were significantly correlated with QOL in the BD group. Resilience was significantly associated with overall QOL, physical subdomains of QOL, psychological subdomains of QOL, social subdomains of QOL, and environmental subdomains of QOL in the BD group, even after controlling for confounders. In the control group, resilience was significantly associated with overall QOL, the physical subdomains of QOL, psychological subdomains of QOL, and social subdomains of QOL.

LIMITATIONS

The number of participants in each group was 68, which is a relatively small sample size.

CONCLUSIONS

Resilience in patients with BD was independently and positively correlated with various areas of QOL. Various strategies to reinforce resilience in patients with BD are needed to improve the low QOL in this population.

Psychosocial profile of pediatric brain tumor survivors with neurocognitive complaints

PURPOSE

With more children surviving a brain tumor, neurocognitive consequences of the tumor and its treatment become apparent, which could affect psychosocial functioning. The present study therefore aimed to assess psychosocial functioning of pediatric brain tumor survivors (PBTS) in detail.

METHODS

Psychosocial functioning of PBTS (8-18 years) with parent-reported neurocognitive complaints was compared to normative data on health-related quality of life (HRQOL), self-esteem, psychosocial adjustment, and executive functioning (one-sample t tests) and to a sibling control group on fatigue (independent-samples t test). Self-, parent-, and teacher-report questionnaires were included, where appropriate, providing complementary information.

RESULTS

Eighty-two PBTS (mean age 13.4 years, SD 3.2, 49 % males) and 43 healthy siblings (mean age 14.3, SD 2.4, 40 % males) were included. As compared to the normative population, PBTS themselves reported decreased physical, psychological, and generic HRQOL (d = 0.39-0.62, p < 0.008). Compared to siblings, increased fatigue-related concentration problems (d = 0.57, p < 0.01) were reported, although self-reported self-esteem and psychosocial adjustment seemed not to be affected. Parents of PBTS reported more psychosocial (d = 0.81, p < 0.000) and executive problems (d = 0.35-0.43, p < 0.016) in their child than parents of children in the normative population. Teachers indicated more psychosocial adjustment problems for female PBTS aged 8-11 years than for the female normative population (d = 0.69, p < 0.025), but they reported no more executive problems.

CONCLUSIONS

PBTS with parent-reported neurocognitive complaints showed increased psychosocial problems, as reported by PBTS, parents, and teachers.

IMPLICATIONS FOR CANCER SURVIVORS

Systematic screening of psychosocial functioning is necessary so that tailored support from professionals can be offered to PBTS with neurocognitive complaints.

Quality of life and symptoms in pediatric brain tumor survivors: a systematic review

Little is known about the quality of life of children and youth under the age of 20 who have completed treatment for a pediatric brain tumor. This systematic review was conducted to (a) describe the health-related quality of life (HRQL) outcomes in pediatric brain tumor survivors, (b) identify instruments used to measure HRQL, and (c) determine the relationship between symptoms and HRQL. Using a systematic search and review methodology, databases searched included CINAHL, Medline, Embase, and PsycInfo. No date restrictions were used. Search results elicited 485 articles, of which16 met the inclusion criteria. Compared with their healthy peers, pediatric brain tumor survivors did worse on most measures of physical, psychosocial, social, and cognitive domains of HRQL. Compared with other cancer patients, survivors scored themselves significantly lower on the Pediatric Quality of Life Inventory (PedsQL) social functioning scale, and parents of brain tumor survivors reported lower PedsQL social and total functioning scores for their children. Other variables that were associated with decreased HRQL were degree of hypothalamic tumor involvement, osteopenia, need for special education, older age at diagnosis, greater than 1 year since treatment, and radiation treatment. In these studies, pediatric brain tumor survivors fared worse compared with other cancer survivors or healthy peers on several HRQL domains. Only 3 studies explored the relationship between symptoms, including pain or fatigue, and HRQL in pediatric brain tumor survivors. The relationship between symptoms and HRQL was not well elucidated. More research is needed to explore the multidimensional symptom experience and HRQL outcomes in pediatric brain tumor survivors.

Psychological distress in adolescent and young adult survivors of childhood cancer in Korea

This study examined psychological distress levels, their differences across groups based on sociodemographic and medical variables, and risk factors for significant distress in adolescent and young adult childhood cancer survivors in Korea. Participants consisted of 223 Korean survivors of childhood cancer between 15 and 39 years of age. Psychological distress was measured using the Brief Symptom Inventory-18. A series of t tests, binomial proportion tests, analysis of variance, and univariable and multivariable logistic regressions were used. One fifth of the participants were classified as psychologically distressed. Significant levels of psychological distress were associated with age, economic status, and time since diagnosis. The results indicate a greater need for monitoring and follow-up care related to psychological health in childhood cancer survivors. Outreach and collaboration with health care professionals to increase mental health referrals could provide opportunities to address the needs of childhood cancer survivors in terms of their psychological well-being.

Predisposing Factors to the Quality of Life of Childhood Cancer Survivors

The aim of this study was to examine the predisposing factors to the quality of life of Hong Kong Chinese childhood cancer survivors. A cross-sectional study was conducted with 153 survivors (9-16 years of age) during follow-up at the oncology outpatient clinic. The study found that depressive symptoms are a strong predictor of quality of life in childhood cancer survivors and that systematic screening of this population is important. It is essential for health care professionals to develop, plan, and evaluate interventions with the aim of alleviating depressive symptoms for childhood cancer survivors so as to enhance their quality of life.

Head-to-head comparisons of quality of life instruments for young adult survivors of childhood cancer

PURPOSE

Few studies examine the relevance of health-related quality of life (HRQOL) instruments for young adult survivors of childhood cancer (YASCC). This study compared the psychometric properties of two survivor-specific instruments, the Quality of Life-Cancer Survivor (QOL-CS) and Quality of Life in Adult Cancer Survivor (QLACS).

METHODS

Data from 151 YASCC who enrolled in cancer/tumor registries of two medical centers were used. We examined construct validity by conducting confirmatory factor analysis using indices of chi-square statistic, comparative fit index, and root mean square error of approximation. We examined convergent/discriminant validity by comparing Pearson's correlation coefficients of homogeneous (e.g., physical functioning and pain) of both instruments versus heterogeneous domains (e.g., physical and psychological functioning). We assessed known-groups validity by examining the extent to which HRQOL differed by late effects and comorbid conditions and calculated relative validity (RV) defined as contrasting F-statistics of individual domains to the domain with the lowest F-statistic. Superior known-groups validity is observed if a domain of one instrument demonstrates a higher RV than other domains of the instruments.

RESULTS

YASCC data cannot replicate the constructs both instruments intend to measure, suggesting poor construct validity. Correlations of between-homogeneous and between-heterogeneous domains of both instruments were not discernible, suggesting poor convergent/discriminant validity. Both instruments were equally able to differentiate HRQOL between YASCC with and without late effects and comorbid conditions, suggesting similar known-groups validity.

CONCLUSIONS

Neither instrument is superior. Item response theory is suggested to select high-quality items from different instruments to improve HRQOL measure for YASCC.

Using three legacy measures to develop a health-related quality of life tool for young adult survivors of childhood cancer

BACKGROUND

Little attention has been paid to selecting and developing health-related quality of life (HRQOL) measurement tools for young adult survivors of childhood cancer (YASCC). The primary purpose of this study was to develop a HRQOL tool for YASCC based on three legacy instruments.

METHODS

Data collected from 151 YASCC were analyzed. HRQOL was measured using the Medical Outcomes Study SF-36, Quality of Life in Adult Cancer Survivors, and Quality of Life-Cancer Survivor. We used the following stages to develop our HRQOL tool: mapping items from three instruments into a common HRQOL construct, checking dimensionality using confirmatory factor analyses (CFA), and equating items using Rasch modeling.

RESULTS

We assigned 123 items to a HRQOL construct comprised of six generic and eight survivor-specific domains. CFA retained 107 items that meet the assumptions of unidimensionality and local independence. Rasch analysis retained 68 items that satisfied the indices of information-weighted/outlier-sensitive fit statistic mean square. However, items in most domains possess relatively easy measurement properties, whereas YASCC's underlying HRQOL was on the middle to higher levels.

CONCLUSIONS

Psychometric properties of the established tool for measuring HRQOL of YASCC were not satisfied. Future studies need to refine this tool, especially adding more challenging items.

Health-Related Quality of Life of Young Adult Survivors of Childhood Cancer: A Review of Qualitative Studies

Purpose: The occurrence of late effects, combined with traditional growth and developmental issues, can significantly affect the health-related quality of life (HRQOL) of young adult survivors of childhood cancer (YASCC). Limited HRQOL measurement tools have been developed or validated for YASCC. The purpose of this study was to identify the domains of HRQOL that are unique to YASCC by conducting a systematic review of qualitative studies. Specifically, we compared the findings to the classical framework of HRQOL that was developed for survivors of adult-onset cancer and identified specific domains not being assessed in existing HRQOL instruments for YASCC. Methods: We searched qualitative studies published in peer-reviewed journals from 2000 to 2010 in the PsychINFO, PubMed, and EBSCOhost databases. A set of keywords and inclusion/exclusion criteria were utilized to identify eligible studies with a focus on survivorship and HRQOL issues of YASCC. Results: Sixteen studies met the inclusion/exclusion criteria and were investigated in this study. Six important domains of HRQOL were identified (physical, social, psychological, spiritual, fertility/sexual, resilience, and body appearance) with several sub-domains. Conclusion: Use of the classical HRQOL framework and existing instruments is not comprehensive enough for YASCC. Adding unique domains to the classical framework and existing instruments will make them valuable tools for measuring the HRQOL of YASCC and increase health professionals' ability to identify if and when psychosocial services are needed for this unique population.

Might salicylate exert benefits against childhood cancer?

Childhood cancers are a broad range of diseases. Research on the chemopreventive potential of non-steroidal anti-inflammatory drugs, such as aspirin (acetylsalicylate) has yet to be fully directed towards childhood cancers. A prima facie hypothesis on salicylate and childhood cancer would therefore be based on several factors. Firstly, salicylate inhibits the production of inflammatory prostaglandins, which have been shown to stimulate the growth of cancer cells. Secondly, salicylate inhibits the growth of cancer cells in pre-clinical models. Thirdly, salicylate is a natural component of fruits and vegetables so it is consumed within the diet. Further research, of which some possibilities are identified, is recommended.
