Social outcomes in young adult survivors of low incidence childhood cancers

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.

Recommendations for the surveillance of education and employment outcomes in survivors of childhood, adolescent, and young adult cancer: A report from the International Late Effects of Childhood Cancer Guideline Harmonization Group

Educational achievement and employment outcomes are critical indicators of quality of life in survivors of childhood, adolescent, and young adult (CAYA) cancer. This review is aimed at providing an evidence-based clinical practice guideline (CPG) with internationally harmonized recommendations for the surveillance of education and employment outcomes in survivors of CAYA cancer diagnosed before the age of 30 years. The CPG was developed by a multidisciplinary panel under the umbrella of the International Late Effects of Childhood Cancer Guideline Harmonization Group. After evaluating concordances and discordances of 4 existing CPGs, the authors performed a systematic literature search through February 2021. They screened articles for eligibility, assessed quality, and extracted and summarized the data from included articles. The authors formulated recommendations based on the evidence and clinical judgment. There were 3930 articles identified, and 83 of them, originating from 17 countries, were included. On a group level, survivors were more likely to have lower educational achievement and more likely to be unemployed than comparisons. Key risk factors for poor outcomes included receiving a primary diagnosis of a central nervous system tumor and experiencing late effects. The authors recommend that health care providers be aware of the risk of educational and employment problems, implement regular surveillance, and refer survivors to specialists if problems are identified. In conclusion, this review presents a harmonized CPG that aims to facilitate evidence-based care, positively influence education and employment outcomes, and ultimately minimize the burden of disease and treatment-related late adverse effects for survivors of CAYA cancers. LAY SUMMARY: A multidisciplinary panel has developed guidelines for the surveillance of education and employment outcomes among survivors of childhood, adolescent, and young adult cancer. On the basis of evidence showing that survivors are at risk for lower educational achievement and unemployment, it is recommended that all survivors receive regular screening for educational and employment outcomes.

Living as a Cancer Survivor: A Qualitative Study on the Experiences of Belgian Adolescents and Young Adults (AYAs) after Childhood Cancer

PURPOSE

Insight was sought in how a childhood cancer experience plays a role in daily life of adolescents and young adults (AYA) survivors.

DESIGN AND METHODS

A qualitative research in which semi-structured interviews were held with 21 AYA survivors of childhood cancer between the ages of 14 and 25. The AYA survivors were recruited from two pediatric oncology departments of two university hospitals in Belgium.

RESULTS

The current situation and behavior of AYA-survivors who have been treated for childhood cancer are covered in 5 categories: The Feeling of Being Different while Aiming for Normalcy in Relationships, Living with Existential Uncertainty, The Conscious Protection of Health, The Attachment to the Parent(s) with Whom the Cancer Experience was Shared, and The Desire to Be Meaningful to Others.

CONCLUSIONS

The AYA survivors did not feel that their cancer experience dominated their current daily life, yet, the cancer experience had an important impact on their functioning.

PRACTICE IMPLICATIONS

The findings of the study can be used to optimize holistic psychosocial care of AYA survivors. By starting from the key elements in their current functioning, health care professionals can tailor their support to the way in which AYA survivors have integrated their cancer experience into their everyday lives.

Educational attainment of childhood cancer survivors: A systematic review

Background

Advances in treatment mean that most children diagnosed with cancer during childhood survive. Therefore, it is increasingly important to examine the long‐term consequences of childhood cancer, including educational attainment. This systematic review investigated whether the educational attainment of childhood cancer survivors differ from the cancer‐free population.

Design/methods

We searched seven databases for articles published from January 2005 to August 2018. We identified full papers in English, reporting primary data on academic attainment of adult survivors of childhood cancer, compared to a control group. Quality appraisal was conducted using the Newcastle‐Ottawa Scale.

Results

Fourteen studies met the inclusion criteria. Nine papers included patients with various types of cancers, four focused on a single type of cancer, and one on patients who underwent stem cell transplantation.

Of the 14 papers, 2 studies were considered good quality, 10 were considered adequate quality, and 2 were considered poor quality. Four studies reported more favorable educational attainment among survivors while six did not report significant differences. Less favorable attainment was consistently reported for CNS survivors in four studies.

Conclusion

The literature does not provide a clear pattern of the long‐term consequences of childhood cancer on education attainment. While this may suggest that there is no consistent difference between the education attainment of cancer survivors and controls, it may also be the result of limitations in the existing research. To better assess the education attainment of survivors, there is a need for high‐quality studies, with appropriate comparators, and standardized measures of education attainment across countries.

Occupational status among adult survivors following allogeneic stem cell transplantation in childhood

This study examined occupational status and factors associated with sick leave and disability pension among adult long-term survivors previously treated with allogeneic stem cell transplantation (allo-SCT) during childhood. Moreover, occupational status was compared to that of a reference group. Data were collected with questionnaires and from medical records. The SCT group included 59 adults (18-45 years old: response rate 63%) treated with allo-SCT in childhood with a median of 17 (range 3-28) years earlier. The reference group included 296 individuals randomly selected from the general population. The results show that 54% of the long-term survivors were working part- or full-time and that 19% were on sick leave or disability pension. A larger proportion of the SCT group was on sick leave or disability pension (19% vs. 6%: p < .001) than of the reference group. The logistic regression analysis revealed that being on sick leave or disability pension among long-term survivors was associated with late effects related to the allo-SCT (OR 12.28: 95% CI 1.3-111.6: p = .03). The results underscore that long-term survivors' engagement in paid work is influenced many years after treatment and highlights the need to include vocational assistance in the rehabilitation following allo-SCT in childhood.

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.

Prescriptions of Antidepressants to Survivors of Cancer in Childhood, Adolescence, and Young Adulthood: A Population-Based Study

PURPOSE

Survivors of cancer may experience higher rates of psychological problems requiring pharmacological interventions than age-matched controls from the general population. This study compares prescription rates of antidepressants in survivors of cancer, diagnosed in childhood, adolescence, or early adulthood, to the rate in age- and gender-matched controls from the Norwegian population.

METHODS

Antidepressants prescribed to 5341 cancer survivors, diagnosed ≤25 years during 1965-2000, were studied in a population-based cohort by linking data from the following nationwide registries: the Population Registry of Norway, the Cancer Registry of Norway, and the Norwegian Prescription Database. For each survivor, three age- and gender-matched controls were randomly selected from the population. A Cox proportional hazard model was applied to estimate hazard ratios (HRs) of antidepressant prescriptions during 2004-2012 to the survivors with controls as referents.

RESULTS

Survivors had an increased risk of being prescribed antidepressants with crude rates of 26.9/1000 person-years compared with 22.5/1000 person-years in controls (HR 1.19; 95% confidence interval [CI] 1.12-1.28). The relative risk was highest for survivors of central nervous system tumors (HR 1.30; 95% CI 1.04-1.63), leukemias (HR 1.29; 95% CI 1.03-1.63), testicular tumors (HR 1.27; 95% CI 1.04-1.55), and "other tumors" (HR 1.42; 95% CI 1.10-1.84). No effect of age at cancer diagnosis was found.

CONCLUSION

Certain groups of survivors of cancer in childhood, adolescence, or young adulthood have a slightly increased risk for being prescribed antidepressants than their peers. The results may indicate an increased prevalence of depression among these survivors, but diagnostic reasons for prescriptions need to be confirmed in clinical studies.

Danish Childhood Cancer Registry

Aim of database

The overall aim is to monitor the quality of childhood cancer care in Denmark; to register late effects of treatment; to analyze complications of permanent central venous catheters (CVCs); to study blood stream infections in children with cancer; and to study acute toxicity of high-dose methotrexate infusions in children with leukemia.

Study population

All children below 15 years of age at diagnosis living in Denmark diagnosed after January 1, 1985 according to the International Classification of Diseases 10, including diagnoses DC00–DD48.

Main variables

Cancer type, extent of disease, treatment, participation in international studies, recurrence of malignant disease, survival, yearly follow-up status, causes of death, and development of secondary malignancies. Type of CVC, causes for removal of the CVC, type of blood stream infection, pathogens isolated, antimicrobial sensitivity, and outcome of antimicrobial chemotherapy.

Descriptive data

Since 1985, 4,944 children below 15 years of age have been registered in the database. There has been no significant change in the incidence of childhood cancer in Denmark since 1985. The 5-year survival has increased significantly since 1985 and is now 86%. The median number of days from diagnosis to initiation of therapy is 7 days and in 80% of the children less than 14 days. Clinical data of 95% of the patients are reported to open international studies.

Conclusion

The survival of Danish children with cancer since 2003 compares favorably with other international population-based studies. The annual reports support the collaboration within pediatric oncology in Denmark.

Employment in French young adult survivors of childhood leukemia: an LEA study (for Leucemies de l'Enfant et de l'Adolescent-childhood and adolescent leukemia)

PURPOSE

Our principal aim was to assess the occupational outcomes of French survivors of childhood leukemia, compared to national population. The secondary objective was to identify determinants linked with employment stability after childhood leukemia.

METHODS

All survivors aged 15 and over enrolled in the French LEA Cohort (Childhood and Adolescent Leukemia) were included. Occupational data were self-reported. The occupational distributions expected in the cohort for each age range were established based on the distribution in France as reference, and comparisons between observed and expected distributions were performed. Logistic regression model was used to explore determinants of stability of survivors' employment.

RESULTS

The questionnaire was completed by 845 eligible survivors (response rate 87.8 %), with a mean age of 22.3 ± 5.4 years and a mean follow-up duration of 14.3 ± 6.3 years. Among the 361 survivors currently in the labor market, 36 (10.0 %) were seeking a job, which is significantly lower than expected (19.3 %) compared to French population. Conversely, among those currently employed, the number of survivors in unstable employment (43.9 %) was significantly higher than expected (33.5 %). Younger age and higher number of late effects were risk factors for unstable employment.

CONCLUSIONS

While the employment rate of the young French adult population of childhood leukemia survivors seems rather positive, access to a steady job appears to be compromised for some survivors.

IMPLICATIONS FOR CANCER SURVIVORS

A strategy to better identify particular subgroups of survivors at greatest risk for difficulties in their professional achievement will help ensure the development of specific intervention strategies and support procedures.

Recent employment trend of childhood cancer survivors in Japan: a cross-sectional survey

BACKGROUND

Previous research has shown that some adult childhood cancer survivors (CCSs) have experienced employment difficulties. However, the actual employment status of CCSs in Japan has not been studied.

PARTICIPANTS AND METHODS

The participants were selected from the membership directory of Heart Link mutual-aid health insurance and recruited by the Childhood Cancer Patients' Network. We conducted a cross-sectional survey (a self-rated questionnaire on employment) via postal mail or an email communication with a link to an Internet website. We explored the association between the characteristics of CCSs who require disability qualification and having experienced unemployment. The adjusted odds ratios (ORs) for the factors with an outcome of interest were estimated with logistic regression analysis.

RESULTS

In total, 44 CCSs indicated that they had a disability qualification. The significant independent factors related to needing a disability qualification were late effects [OR 12.3; 95 % confidence interval (CI) 3.37-45.2], brain tumors (OR 9.55; 95 % CI 1.90-48.0), and being a high school graduate (OR 9.86; CI 2.67-36.4). The unemployment rate was 15.9 % among CCSs, excluding homemakers and students. Approximately 70 % of unemployed CCSs had some late effects; independent factors related to unemployment were late effects (OR 6.22; 95 % CI 1.80-21.40), dropping out of school (OR 8.46; 95 % CI 1.66-43.10), and brain tumors (OR 2.73; 95 % CI 0.83-8.96). Most unemployed CCSs were likely to seek work, despite their health problems.

CONCLUSIONS

The unemployment rate is not high in Japan, but some CCSs need extended disability qualification. The independent factors related to unemployment were late effects and dropping out of school.

Psychosocial Care of Adolescent and Young Adult Patients With Cancer and Survivors

The delivery of quality care for adolescent and young adult (AYA) patients with cancer and survivors requires an understanding of the unique qualities of this group—the shared norms, attitudes, and beliefs that determine their behavior as well as the unique stresses they face on a day-to-day basis. All AYAs have typical concerns about being comfortable with who they are and who they want to become (identity development, including sexual identity), their bodies (body image), initiating intimate and emotional relationships, separating from parents, and making independent decisions about future goals such as career, higher education, and/or family (autonomy). Yet efforts of AYA patients with cancer and survivors to mature are often confounded by restrictions and limitations placed on them by their disease and treatment. This article promotes understanding of psychosocial challenges faced by AYAs when diagnosed with and treated for cancer. It reviews evidence-based psychosocial support interventions for AYAs with cancer and other life-threatening or chronic diseases, particularly the positive effects of peer support, technology-based interventions, and skill-based interventions. The article concludes with recommendations for clinical care that are intended to promote the ability of AYAs to cope with cancer.

Increased prevalence of chronic fatigue among survivors of childhood cancers: a population-based study

BACKGROUND

Fatigue is prevalent in adult cancer survivors but less studied in childhood cancer survivors. Aims were to assess fatigue levels, prevalence of chronic fatigue (CF) and the association of CF with health-related quality of life (HRQoL) in survivors of acute myeloid leukemia (AML), infratentorial astrocytoma (IA), and Wilms tumor (WT) in childhood.

PROCEDURE

Seventy percent (398/567) of Nordic patients treated for AML, IA, and WT between 1985 and 2001 at age >1 year responded to a postal survey, encompassing the Fatigue Questionnaire and the Short Form 36 (SF-36). Participants were divided into two groups at time of study; younger (YG, 13-18 years) and older (OG, 19-34 years). Respondents (19-34 years, n = 763) from a Norwegian general population (GP) survey served as controls for the OG.

RESULTS

The OG [mean age was 24 years (SD 3.3)] had higher fatigue levels compared to the YG and the GP, especially the females (P < 0.05). There was also a higher prevalence of CF in the OG than in the GP (14 vs. 6%, P < 0.001). Regardless of diagnosis, the OG with CF had poorer physical health (P < 0.05) on the SF-36 but better mental health (P < 0.05 and P = 0.001) relative to controls with CF.

CONCLUSIONS

The prevalence of CF is higher among Nordic survivors of AML, IA, and WT than GP controls of similar age. CF is associated with impaired HRQoL in survivors. However, they reported better mental health than CF GP controls. This might indicate different underlying mechanisms of CF in the two populations.

Predictors of independent living status in adult survivors of childhood cancer: a report from the Childhood Cancer Survivor Study

BACKGROUND

Adult survivors of childhood cancer and their siblings are compared on one of the most salient developmental milestones of adulthood, the ability to live independently.

PROCEDURE

Adult survivors of childhood cancers (n = 6,047) and siblings (n = 2,326), all 25 years of age and older, completed a long-term follow-up questionnaire that assessed adaptive, neurocognitive, and psychological functioning, as well as demographic and health status. Multivariable logistic regression analyses and structural equation modeling (SEM) were used to identify predictors of independent living.

RESULTS

Compared to siblings (n = 206, 8.7%), survivors (n = 1063; 17.7%) were more than twice as likely to live dependently (OR 2.07; 95% confidence interval [CI] 1.77-2.42). Survivors diagnosed with CNS tumors (OR 0.13, 95% CI 0.10-0.18) or leukemia (OR 0.29, 95% CI 0.23-0.27) were significantly less likely to live independently compared to those diagnosed with Hodgkin lymphoma. Other risk factors for reduced independent living included cranial radiation (≤ 24 Gy OR 0.76, 95% CI 0.62-0.93; >24 Gy OR 0.31, 95% CI 0.24-0.41), use of neuroleptic, anticonvulsant, or psychostimulant medication (OR 0.32, 95% CI 0.24-0.43), attention and processing speed problems (OR 0.58, 95% CI 0.47-0.71), poor physical functioning (OR 0.49, 95% CI 0.38-0.63), depression (OR 0.68, 95% CI 0.53-0.88), and racial/ethnic minority status (OR 0.39, 95% CI 0.30-0.51). SEM demonstrated that neurocognitive functioning had both direct effects on independent living status, and indirect effects through use of neurologically directed medication, depression, and poor mental health.

CONCLUSION

Adult survivors of childhood cancer who experience neurocognitive, psychological, or physical late effects are less likely to live independently as adults.

Quality of health in survivors of childhood acute myeloid leukemia treated with chemotherapy only: a NOPHO-AML study

BACKGROUND

More than 60% of children with acute myeloid leukemia (AML) become long-term survivors, and approximately 50% are cured with chemotherapy only. Limited data exist about their long-term morbidity and social outcomes. The aim of the study was to compare the self-reported use of health care services, health experience, social outcomes, and lifestyle behavior of AML survivors with that of their sibling controls.

METHODS

This population-based study included 138 children treated for AML according to the Nordic Society of Pediatric Hematology and Oncology (NOPHO)-AML-84, -88, and -93 trials, and alive by June 30, 2007. Patients treated with hematopoietic stem cell transplantation (HSCT) or relapse were not included. Altogether, 102 (74%) survivors and 91% of their siblings completed a questionnaire.

RESULTS

The median follow-up was 11 (range 4-25) years after diagnosis. AML survivors had no increased rate of hospitalization compared with sibling controls, but were more often receiving prescription drugs, especially for asthma (23% vs. 9%, P = 0.03). Self-reported health experience was excellent or very good in 77% and comparable with that of siblings. Educational achievement, employment, and marital status were comparable in the two groups. Among surviving AML patients, 23% were current smokers and 24% of their siblings were current smokers.

CONCLUSIONS

The self-reported health of children treated on NOPHO-AML protocols without HSCT was good, and their use of health care services was limited. Reported health and social outcomes were comparable to those of their siblings. Many survivors were smoking which may increase the risk of late effects.

Emotional Functioning and School Contentment in Adolescent Survivors of Acute Myeloid Leukemia, Infratentorial Astrocytoma, and Wilms Tumor

Purpose: Cancer in childhood may disrupt normal developmental processes and cause psychosocial problems in adolescent survivors of childhood cancers (ACCSs). Previous studies report inconsistent findings. Study aims were to assess subjective well-being (SWB), psychological distress, and school contentment in survivors of three dissimilar childhood cancers. Patients and methods: Nordic patients treated for acute myeloid leukemia (AML), infratentorial astrocytoma (IA), and Wilms tumor (WT) in childhood from 1985 to 2001, aged ≥1 year at diagnosis, and aged 13-18 years at the time of study were eligible for this questionnaire-based survey that included items on SWB, psychological distress, school contentment, self-esteem, and personality traits; 65% (151/231) responded. An age-equivalent group from a Norwegian health survey (n=7910) served as controls. Results: The median age of ACCSs was 16 years; 52% were males. ACCSs reported better SWB (p=0.004) and self-esteem (p<0.001). They had fewer social problems in school (p=0.004) and their school contentment tended to be higher than controls. SWB and school contentment were positively influenced by self-esteem. However, ACCSs reported higher levels of psychological distress (p=0.002), mostly attributable to general worrying. No significant differences in outcomes were found across diagnoses, and time since diagnosis did not significantly affect the results. Conclusion: The overall emotional functioning of ACCSs was good, possibly due to changes in their perception of well-being after having survived a life-threatening disease. However, they seemed more worried than their peers. This may cause an additional strain at a vulnerable period in life.

Social outcomes and quality of life of childhood cancer survivors in Japan: a cross-sectional study on marriage, education, employment and health-related QOL (SF-36)

Social outcomes and quality of life (QOL) of childhood cancer survivors (CCSs) remain unknown in Japan. We investigated these outcomes in young adult CCSs compared to those of their siblings in Japan, and analyzed the association between social outcome and SF-36 health survey subscale scores. Between 2007 and 2009, we performed a cross-sectional survey using self-rating questionnaires. We estimated social outcomes and health-related QOL by performing the SF-36 in each group: CCSs with or without stem cell transplantation (SCT)/radiotherapy (RT) and their siblings. Adjusted odds ratios for outcomes of interest were estimated using logistic regression analysis. Questionnaires from 185 CCSs and 72 CCS's siblings were analyzed. There were no differences in educational attainment or annual income. The SF-36 subscale scores of CCSs with SCT and RT were significantly lower than those of siblings in physical functioning (PF) (p < 0.001 and 0.003, respectively) and general health (GH) (both p = 0.001). Lower PF scores correlated with recurrence (p = 0.041) and late effects (p = 0.010), and poor GH scores with late effects (p = 0.006). The CCSs had made efforts to attain educational/vocational goals; however, a significant proportion of CCSs who had experienced late effects remain at increased risk of experiencing diminished QOL.
