Early mortality in children with cancer in Denmark and Sweden: The role of social background in a setting with universal healthcare

Socioeconomic differences in overall survival from childhood cancer have been shown previously, but the underlying mechanisms remain unclear. We aimed to investigate if social inequalities were seen already for early mortality in settings with universal healthcare. From national registers, all children diagnosed with cancer at ages 0-19 years, during 1991-2014, in Sweden and Denmark, were identified, and information on parental social characteristics was collected. We estimated odds ratios (OR) and 95% confidence intervals (CI) of early mortality (death within 90 days after cancer diagnosis) by parental education, income, employment, cohabitation, and country of birth using logistic regression. For children with acute lymphoblastic leukaemia (ALL), clinical characteristics were obtained. Among 13,926 included children, 355 (2.5%) died within 90 days after diagnosis. Indications of higher early mortality were seen among the disadvantaged groups, with the most pronounced associations observed for maternal education (ORadj_Low_vs_High 1.65 [95% CI 1.22-2.23]) and income (ORadj_Q1(lowest)_vs_Q4(highest) 1.77 [1.25-2.49]). We found attenuated or null associations between social characteristics and later mortality (deaths occurring 1-5 years after cancer diagnosis). In children with ALL, the associations between social factors and early mortality remained unchanged when adjusting for potential mediation by clinical characteristics. In conclusion, this population-based cohort study indicated differences in early mortality after childhood cancer by social background, also in countries with universal healthcare. Social differences occurring this early in the disease course requires further investigation, also regarding the timing of diagnosis.

Incidence and prevalence of musculoskeletal health conditions in survivors of childhood and adolescent cancers: A report from the Swiss childhood cancer survivor study

PURPOSE

Childhood cancer and its treatment can cause damage to the musculoskeletal system. We aimed to determine the incidence and prevalence of musculoskeletal health conditions (MSHC) in survivors, and to investigate differences by cancer-related characteristics.

METHODS

We used data from the Childhood Cancer Registry and the Swiss Childhood Cancer Survivor Study, including survivors (≥5 years since diagnosis; diagnosed 1976-2015 at <20 years of age) aged ≥15 years at study. Cumulative incidence and prevalence of MSHCs (osteoporosis, limb length discrepancy, limited joint mobility, bone/joint pain, scoliosis, changes to chest/ribs and amputation) were calculated from self-reported data.

RESULTS

We included 2645 survivors (53% men; median age 24 years, range 15-59 years). Prevalence and cumulative incidence of any MSHC was 21% and 26%, respectively. Incidence rate for any MSHC was 15.6/1000 person-years. Scoliosis (8%), bone/joint pain (7%) and limited joint mobility (7%) were the most prevalent MSHC. MSHC co-occurred with other health conditions in 87% of survivors. We found increased rates of MSHC in women (RR = 1.4, 95%CI: 1.2-1.7), bone tumour survivors (RR = 6.0, 95%CI: 4.5-7.9), survivors older at diagnosis (11-15 years: RR = 1.8, 95%CI: 1.5-2.3), after a relapse (RR = 1.5, 95%CI: 1.3-1.9), treatment with surgery (RR = 1.2, 95%CI: 1.0-1.5), chemotherapy (RR = 1.4, 95%CI: 1.1-1.8) or stem cell transplantation (RR = 1.6, 95%CI: 1.0-2.5), and more recent year of diagnosis (2011-2015: RR = 4.3, 95%CI: 2.8-6.8).

CONCLUSION

MSHCs are prevalent in survivors, the risk is increasing in younger survivor cohorts, and MSHCs usually occur in multimorbid survivors. Strengthening of rehabilitation services and appropriate referrals are needed to mitigate the effects of the cancer and cancer treatment.

Post-traumatic growth in parents of long-term childhood cancer survivors compared to the general population: A report from the Swiss childhood cancer survivor study-Parents

OBJECTIVE

Post-traumatic growth (PTG) describes perceived positive changes following a traumatic event. We describe (i) PTG in parents of long-term childhood cancer survivors (CCS-parents) compared to parents of similar-aged children of the general population (comparison-parents), (ii) normative data for the Swiss population, and (iii) psychological, socio-economic, and event-related characteristics associated with PTG.

METHODS

CCS-parents (aged ≤16 years at diagnosis, ≥20 years old at study, registered in the Childhood Cancer Registry Switzerland (ChCR), and the Swiss population responded to a paper-based survey, including the PTG-Inventory (total score 0-105). We carried out (i) t-tests, (ii) descriptive statistics, and (iii) multilevel regression models with survivor/household as the cluster variable.

RESULTS

In total, 746 CCS-parents (41.7% fathers, response-rate = 42.3%) of 494 survivors (median time since diagnosis 24 (7-40) years), 411 comparison-parents (42.8% fathers, 312 households), and 1069 individuals of the Swiss population (40.7% male, response-rate = 20.1%) participated. Mean [M] total PTG was in CCS-parents M = 52.3 versus comparison-parents M = 50.4, p = 0.078; and in the Swiss population M = 44.5). CCS-parents showed higher 'relating-to-others' (18.4 vs. 17.3, p = 0.010), 'spiritual-change' (3.3 vs. 3.0, p = 0.038) and 'appreciation-of-life' (9.3 vs. 8.4, p = 0.027) than comparison-parents, but not in 'new-possibilities' and 'personal-strength'. Female gender, older age, higher post-traumatic stress, and higher resilience were positively associated with PTG. Individuals reporting events not typically classified as traumatic also reported growth.

CONCLUSIONS

Our findings highlight that mothers and fathers can experience heightened growth many years after their child's illness. Being able to sensitively foreshadow the potential for new-possibilities and personal development may help support parents in developing a sense of hope.

Longitudinal assessment of lung function in Swiss childhood cancer survivors-A multicenter cohort study

OBJECTIVE

Childhood cancer survivors are at risk for pulmonary morbidity due to exposure to lung-toxic treatments, including specific chemotherapeutics, radiotherapy, and surgery. Longitudinal data on lung function and its change over time are scarce. We investigated lung function trajectories in survivors over time and the association with lung-toxic treatments.

METHODS

This retrospective, multicenter cohort study included Swiss survivors diagnosed between 1990 and 2013 and exposed to lung-toxic chemotherapeutics or thoracic radiotherapy. Pulmonary function tests (PFTs), including forced expiration volume in the first second (FEV1), forced vital capacity (FVC), FEV1/FVC, total lung capacity,  and diffusion capacity of the lung for carbon monoxide, were obtained from hospital charts. We calculated z-scores and percentage predicted, described lung function over time, and determined risk factors for change in FEV1 and FVC using multivariable linear regression.

RESULTS

We included 790 PFTs from 183 survivors, with a median age of 12 years at diagnosis and 5.5 years of follow-up. Most common diagnosis was lymphoma (55%). Half (49%) of survivors had at least one abnormal pulmonary function parameter, mainly restrictive (22%). Trajectories of FEV1 and FVC started at z-scores of -1.5 at diagnosis and remained low throughout follow-up. Survivors treated with thoracic surgery started particularly low, with an FEV1 of -1.08 z-scores (-2.02 to -0.15) and an FVC of -1.42 z-scores (-2.27 to -0.57) compared to those without surgery.

CONCLUSION

Reduced pulmonary function was frequent but mainly of mild to moderate severity. Nevertheless, more research and long-term surveillance of this vulnerable population is needed.

Long-term social and professional outcomes in adults after pediatric kidney failure

BACKGROUND

Little is known about the long-term social and professional outcomes in adults after pediatric kidney replacement therapy (KRT). In this study, we described social and professional outcomes of adults after kidney failure during childhood and compared these outcomes with the general population.

METHODS

We sent a questionnaire to 143 individuals registered in the Swiss Pediatric Renal Registry (SPRR) with KRT starting before the age of 18 years. In the questionnaire, we assessed social (partner relationship, living situation, having children) and professional (education, employment) outcomes. Logistic regression models adjusted for age at study and sex were used to compare outcomes with a representative sample of the Swiss general population and to identify socio-demographic and clinical characteristics associated with adverse outcomes.

RESULTS

Our study included 80 patients (response rate 56%) with a mean age of 39 years (range 19-63). Compared to the general population, study participants were more likely to not have a partner (OR = 3.7, 95%CI 2.3-5.9), live alone (OR = 2.5, 95%CI 1.5-4.1), not have children (OR = 6.8, 95%CI 3.3-14.0), and be unemployed (OR = 3.9, 95%CI 1.8-8.6). No differences were found for educational achievement (p = 0.876). Participants on dialysis at time of study were more often unemployed compared to transplanted participants (OR = 5.0, 95%CI 1.2-21.4) and participants with > 1 kidney transplantation more often had a lower education (OR = 3.2, 95%CI 1.0-10.2).

CONCLUSIONS

Adults after pediatric kidney failure are at risk to experience adverse social and professional outcomes. Increased awareness among healthcare professionals and additional psycho-social support could contribute to mitigate those risks. A higher resolution version of the Graphical abstract is available as Supplementary information.

Education, Employment, and Financial Outcomes in Adolescent and Young Adult Cancer Survivors-A Systematic Review

Adolescents and young adults (AYAs) with cancer face unique challenges. We aimed to describe (i) education, employment, and financial outcomes and (ii) determinants for adverse outcomes in AYA cancer survivors. We performed a systematic literature search. We included original research articles on AYA (15-39 years of age) cancer survivors (≥2 years after diagnosis) and our outcomes of interest. We narratively synthesized the results of the included articles. We included 35 articles (24 quantitative and 11 qualitative studies). Patients in education had to interrupt their education during cancer treatment, and re-entry after treatment was challenging. After treatment, most survivors were employed but started their employment at an older age than the general population. Overall, no disadvantages in income were found. Survivors reported more absent workdays than comparisons. We identified chemotherapy, radiotherapy, late effects or health problems, female sex, migration background, and lower education associated with adverse outcomes. Although most AYA cancer survivors were able to re-enter education and employment, they reported difficulties with re-entry and delays in their employment pathway. To facilitate successful re-entry, age-tailored support services should be developed and implemented.

Income disparities between adult childhood cancer survivors and their peers-A register-based cohort study from the SALiCCS research programme

BACKGROUND

Childhood cancer survivors face various adverse consequences. This Nordic register-based cohort study aimed to assess whether survivors of childhood cancer are more likely to have low income than their peers.

METHODS

We identified 17,392 childhood cancer survivors diagnosed at ages 0 to 19 between 1971 and 2009 with 83,221 age-, sex-, and country-matched population comparisons. Annual disposable income at ages 20 to 50 years was retrieved from statistical offices (for 1990-2017) and categorized into low income and middle/high income. The number of transitions between income categories were assessed using binomial regression analyses.

RESULTS

The prevalence of annual low income among childhood cancer survivors was 18.1% and 15.6% among population comparisons (risk ratio [RR] 1.17; 95% confidence interval [CI] 1.16-1.18). Compared to population comparisons, childhood cancer survivors were 10% (95% CI 8%-11%) less likely to transition from low to middle/high income and 12% (10%-15%) more likely to transition from middle/high to low income during follow-up. Among those initially in the low income category, survivors were 7% (95% CI 3%-11%) more likely to remain in the low income category. If the initial category was middle/high income, childhood cancer survivors were 10% (95% CI 8%-11%) less likely to remain in the middle/high income and 45% (37%-53%) more likely to transition to the low income category permanently.

CONCLUSIONS

Childhood cancer survivors are at higher risk for low income in adulthood than their peers. These disparities might be reduced by continued career counseling along with support in managing within the social security system.

Worries and anxiety in parents of adult survivors of childhood cancer: A report from the Swiss Childhood Cancer Survivor Study-Parents

OBJECTIVE

Having a child diagnosed with cancer is distressing for parents. We aimed to compare worries and anxiety in parents of adult childhood cancer survivors with parents of the Swiss general population (GP-parents), and to evaluate characteristics associated with worry in parents of survivors.

METHODS

We conducted a nationwide, population-based study in parents of survivors (survivors aged ≥20 years at study, ≤16 years at diagnosis, >5 years post diagnosis) and GP-parents (≥1 child aged ≥20 years at study). We used the Worry and Anxiety Questionnaire (WAQ), and computed the WAQ total score (worries; possible range 0-80) and caseness for generalized anxiety disorder (anxiety), cognitive, somatic, and any criteria. We used multilevel, multivariable linear regression to identify characteristics associated with worries in parents of survivors.

RESULTS

We included 787 parents of 513 survivors (41.0% fathers) and 478 GP-parents (42.3% fathers). Parents of survivors and GP-parents did not differ regarding worries (16.6 vs. 17.1, p = .977), anxiety (2.7% vs. 3.6%, p = .536), cognitive (p = .440), and somatic criteria (p = .067). Less parents of survivors met any criteria (17.7% vs. 24.0%, p = .039). Half of parents reported current cancer-related worries. Higher cancer-related worries were reported by mothers (β = 4.1; 95% CI: 2.0-6.2), parents with one child (β = 5.9; 95% CI: 2.0-9.7), currently experiencing disadvantages because of their child's former disease (β = 7.3; 95% CI: 4.0-10.6), or with support needs (β = 9.0; 95% CI: 3.9-14.2; p = .001).

CONCLUSIONS

It is encouraging that most parents of adult survivors report similar worries and anxiety as GP-parents, but cancer-related worries are still prevalent. Efforts should be made to empower parents to seek psycho-social support if required.

Health-related quality of life before and during the COVID-19 pandemic in Switzerland: a cross-sectional study

INTRODUCTION

The COVID-19 pandemic forced people to give up their daily routines and adjust to new circumstances. This might have affected health-related quality of life (HRQOL). We aimed to compare HRQOL during the first COVID-19 wave in 2020 to HRQOL before the pandemic and to identify determinants of HRQOL during the pandemic in Switzerland.

METHODS

We conducted a cross-sectional online survey during the pandemic (between May and July 2020; CoWELL sample; convenience sample). Before the pandemic (2015-2016), we had conducted a cross-sectional paper-based survey among a representative random sample of the Swiss general population (SGP sample). In both samples, we assessed physical and mental HRQOL (Short Form-36) and socio-demographic characteristics. In the CoWELL sample, we additionally assessed health- and COVID-19-related characteristics. Data were analysed using linear regressions.

RESULTS

The CoWELL sample included 1581 participants (76% women; mean age = 43 years, SD = 14 years) and the SGP sample 1209 participants (58% women, mean age = 49 years, SD = 15 years). Adjusted for sex, age, and education, the CoWELL sample reported higher physical HRQOL (PCS, +5.8 (95% CI: 5.1, 6.6), p < 0.001) and lower mental HRQOL (MCS, -6.9 (-7.8, -6.0), p < 0.001) than the SGP sample. In the CoWELL sample, especially persons with lower health literacy, who had no support network or who have had COVID-19, reported lower HRQOL.

DISCUSSION

Aspects unique to the COVID-19 pandemic affected HRQOL. Vulnerable persons such as those having had COVID-19, less support opportunities, and with lower health literacy are especially prone to impaired HRQOL during the COVID-19 pandemic.

Risk of subsequent primary lymphoma in a cohort of 69,460 five-year survivors of childhood and adolescent cancer in Europe: The PanCareSurFup study

BACKGROUND

Survivors of Hodgkin lymphoma (HL) are at risk of developing non-Hodgkin lymphoma (NHL) after treatment; however, the risks of developing subsequent primary lymphomas (SPLs), including HL and NHL, after different types of childhood cancer are unknown. The authors quantified the risk of SPLs using the largest cohort of childhood cancer survivors worldwide.

METHODS

The Pan-European Network for Care of Survivors After Childhood and Adolescent Cancer (PanCare) Survivor Care and Follow-Up Studies (PanCareSurFup) cohort includes 69,460 five-year survivors of childhood cancer, diagnosed during 1940 through 2008, from 12 European countries. Risks of SPLs were quantified by standardized incidence ratios (SIRs) and relative risks (RRs) using multivariable Poisson regression.

RESULTS

Overall, 140 SPLs, including 104 NHLs and 36 HLs, were identified. Survivors were at 60% increased risk of an SPL compared with the general population (SIR, 1.6; 95% confidence interval [CI], 1.4-1.9). Survivors were twice as likely to develop NHL (SIR, 2.3; 95% CI, 1.9-2.8), with the greatest risks among survivors of HL (SIR, 7.1; 95% CI, 5.1-10.0), Wilms tumor (SIR, 3.1; 95% CI, 1.7-5.7), leukemia (SIR, 2.8; 95% CI, 1.8-4.4), and bone sarcoma (SIR, 2.7; 95% CI, 1.4-5.4). Treatment with chemotherapy for any cancer doubled the RR of NHL (RR, 2.1; 95% CI, 1.2-3.9), but treatment with radiotherapy did not (RR, 1.2; 95% CI, 0.7-2.0). Survivors were at similar risk of developing a subsequent HL as the general population (SIR, 1.1; 95% CI, 0.8-1.5).

CONCLUSIONS

In addition to HL, the authors show here for the first time that survivors of Wilms tumor, leukemia, and bone sarcoma are at risk of NHL. Survivors and health care professionals should be aware of the risk of NHL in these survivors and in any survivors treated with chemotherapy.

Body image in adolescent survivors of childhood cancer: The role of chronic health conditions

BACKGROUND

Cancer and its treatment may impair the body image of childhood cancer survivors during adolescence. We compared the body image between adolescent cancer survivors and their siblings, and determined whether survivors' body image is associated with socio-demographic characteristics, clinical characteristics and chronic health conditions.

PROCEDURE

As part of the nationwide Swiss Childhood Cancer Survivor Study, we sent questionnaires to adolescents (aged 16-19 years), who survived &gt;5 years after having been diagnosed with childhood cancer between 1989 and 2010. Siblings received the same questionnaire. We assessed the level of agreement with three body image statements referring to body satisfaction and preferences for changes. Chronic health conditions were classified into cardiovascular, pulmonary, endocrine, musculoskeletal, renal/digestive, neurological and hearing or vision impairment. We used ordered logistic regression models to identify determinants of a more negative body image.

RESULTS

Our study included 504 survivors (48% female) with a median age at study of 17.7 years (interquartile range: 16.8-18.6) and 136 siblings. Survivors and siblings reported overall comparable levels of agreement with body image statements (all p &gt; .05). Female survivors (all odds ratio [ORs] ≥1.7), survivors treated with haematopoietic stem cell transplantation (HSCT; all ORs ≥2.2), and survivors with ≥2 chronic health conditions (all ORs ≥1.4) reported a more negative body image. This was particularly pronounced for survivors suffering from musculoskeletal or endocrine conditions.

CONCLUSION

Female survivors, survivors treated with HSCT or with chronic health conditions are at risk of body image concerns during adolescence. Increased awareness among clinicians and targeted psychosocial support could mitigate such concerns.

Health-related quality of life in adults after pediatric kidney failure in Switzerland

BACKGROUND

Little is known about health-related quality of life (HRQoL) in adults after kidney failure during childhood. In this study, we analyzed HRQoL of adults after pediatric kidney failure in Switzerland and investigated socio-demographic and clinical factors associated with HRQoL.

METHODS

In this cohort study, we sent questionnaires to 143 eligible patients registered in the Swiss Pediatric Renal Registry with continuous kidney replacement therapy starting before the age of 18 years. We assessed HRQoL using the Short-Form 36 version 1, compared HRQoL scores between our sample and the Swiss general population, and used linear regression models to examine socio-demographic and clinical factors associated with HRQoL.

RESULTS

We included 79 patients (response rate 55%) with a mean age of 38.6 years (range 19.4-63.1). Compared to the general population, HRQoL scores were lower for physical functioning (- 12.43, p < 0.001), role physical (- 13.85, p = 0.001), general health (- 14.42, p < 0.001), vitality (- 4.98, p = 0.035), and physical HRQoL (- 6.11, p < 0.001), but we found no difference in mental HRQoL (- 0.13, p = 0.932). The socio-demographic factors-lower education, unemployment, and not being in a relationship-were associated with lower HRQoL. The only clinical factor associated with HRQoL was the type of kidney disease. Patients with acquired kidney diseases had lower mental HRQoL than patients with congenital anomalies of the kidney and urinary tract (- 11.4, p = 0.007) or monogenetic hereditary diseases (- 9.5, p = 0.018).

CONCLUSIONS

Adults after pediatric kidney failure in Switzerland have lower physical, but similar mental HRQoL compared to the general population. Subgroups may require special attention with regard to their HRQoL. A higher resolution version of the Graphical abstract is available as Supplementary information.

Severity of hearing loss after platinum chemotherapy in childhood cancer survivors

BACKGROUND

Hearing loss is a potential side effect from childhood cancer treatment. We described the severity of hearing loss assessed by audiometry in a representative national cohort of childhood cancer survivors (CCS) and identified clinical risk factors.

PROCEDURE

We included all CCS from the Swiss Childhood Cancer Registry who were diagnosed ≤18 age and treated with platinum-based chemotherapy between 1990 and 2014. We extracted audiograms, treatment-related information, and demographic data from medical records. Two reviewers independently assessed the severity of hearing loss at latest follow-up using the Münster Ototoxicity Scale. We used ordered logistic regression to identify clinical risk factors for severity of hearing loss.

RESULTS

We analyzed data from 270 CCS. Median time from cancer diagnosis to last audiogram was 5 years (interquartile range 2.5-8.1 years). We found 53 (20%) CCS with mild, 78 (29%) with moderate, and 75 (28%) with severe hearing loss. Higher severity grades were associated with (a) younger age at cancer diagnosis (odds ratio [OR] 5.4, 95% confidence interval [CI]: 2.5-12.0 for <5 years); (b) treatment in earlier years (OR 4.8, 95% CI: 2.1-11.0 for 1990-1995); (c) higher cumulative cisplatin doses (OR 13.5, 95% CI: 4.7-38.8 for >450 mg/m² ); (d) concomitant cranial radiation therapy (CRT) (OR 4.4, 95% CI: 2.5-7.8); and (e) hematopoietic stem cell transplantation (HSCT) (OR 2.7, 95% CI: 1.0-7.2).

CONCLUSION

Three of four CCS treated with platinum-based chemotherapy experienced some degree of hearing loss. We recommend closely monitoring patient's hearing function if treated at a young age with high cumulative cisplatin doses, and concomitant CRT as part of long-term care.

Social, emotional, and behavioral functioning in young childhood cancer survivors with chronic health conditions

BACKGROUND

The cancer diagnosis and its intensive treatment may affect the long-term psycho-social adjustment of childhood cancer survivors. We aimed to describe social, emotional, and behavioral functioning and their determinants in young childhood cancer survivors.

PROCEDURE

The nationwide Swiss Childhood Cancer Survivor Study sends questionnaires to parents of survivors aged 5-15 years, who have survived at least 5 years after diagnosis. We assessed social, emotional, and behavioral functioning using the Strengths and Difficulties Questionnaire (SDQ). The SDQ includes four difficulties scales (emotional, conduct, hyperactivity, peer problems), a total difficulties indicator, and one strength scale (prosocial). We compared the proportion of survivors with borderline and abnormal scores to reference values and used multivariable logistic regression to identify determinants.

RESULTS

Our study included 756 families (response rate of 72%). Thirteen percent of survivors had abnormal scores for the total difficulties indicator compared to 10% in the general population. The proportion of survivors with abnormal scores was highest for the emotional scale (15% vs. 8% in the general population), followed by the peer problems scale (14% vs. 7%), hyperactivity (8% vs. 10%), and conduct scale (6% vs. 7%). Few survivors (4% vs. 7%) had abnormal scores on the prosocial scale. Children with chronic health conditions had a higher risk of borderline and abnormal scores on all difficulties scales (all p < 0.05).

CONCLUSION

Most childhood cancer survivors do well in social, emotional, and behavioral life domains, but children with chronic health conditions experience difficulties. Therefore, healthcare professionals should offer specific psycho-social support to these survivors.

COVID-19 Information-Seeking, Health Literacy, and Worry and Anxiety During the Early Stage of the Pandemic in Switzerland: A Cross-Sectional Study

Objectives: To describe COVID-19 information-seeking behavior (CISB) during the first stage of the pandemic in Switzerland and identify its determinants.

Methods: We conducted an online cross-sectional survey (4 May to 6 July 2020). Participants self-reported their CISB (information sources and frequency), personal COVID-19 situation (e.g., perception about having had COVID-19), sociodemographic information, and completed validated measures of health literacy, and worry and anxiety. Data were analyzed using descriptive statistics and logistic regressions.

Results: We included 1,505 participants (24.7% male; mean age = 43.0 years, SD = 13.9). Most participants reported searching for information daily (n = 1,023, 68.0%) and referring to multiple information sources (mean 3.7, SD = 1.5). Commonly used sources were official websites (n = 1,129, 75.0%) and newspapers (n = 997, 66.2%). Participants with higher health literacy were more likely to seek information daily and use online resources, but less likely to use personal networks than those with lower health literacy. We did not find any association between CISB and worry and anxiety.

Conclusion: More opportunities for personal dialogue and education about reliable online information resources should be encouraged to optimize the CISB of groups with lower health literacy.

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.

The PanCareFollowUp Care Intervention: A European harmonised approach to person-centred guideline-based survivorship care after childhood, adolescent and young adult cancer

BACKGROUND

Long-term follow-up (LTFU) care, although endorsed, is not available for the majority of adult survivors of childhood, adolescence and young adult (CAYA) cancer. Barriers to implementation include lack of time, knowledge, personnel and funding. Sustainable solutions are urgently needed to address the needs of CAYA cancer survivors to improve the quality of life and reduce the burden of late effects on survivors, health care systems and society. The European Union-funded PanCareFollowUp project, initiated by the Pan-European Network for Care of Survivors after Childhood and Adolescent Cancer, was established to facilitate the implementation of person-centred survivorship care across Europe.

PATIENTS AND METHODS

The PanCareFollowUp Care Intervention was co-developed with survivors as part of the PanCareFollowUp project. It is a person-centred approach to survivorship care, supported by guidelines and with flexibility to adapt to local health care settings. The Care Intervention consists of three steps: (1) previsit completion of a Survivor Questionnaire (by the survivor) and Treatment Summary (by the health care provider [HCP]), (2) a clinic visit including shared decision-making, and (3) a follow-up call to finalise the individualised Survivorship Care Plan.

RESULTS

We developed the key components of the PanCareFollowUp Care Intervention: a PanCareFollowUp Survivor Questionnaire, Treatment Summary template, Survivorship Care Plan template, and educational materials for HCPs and survivors. Wide implementation of the PanCareFollowUp Care Intervention will be supported with a freely distributed Replication Manual on completion of the PanCareFollowUp project.

CONCLUSIONS

The PanCareFollowUp Care Intervention will support the implementation of person-centred, guideline-based LTFU care in different health care settings across Europe to improve survivors' health and well-being.

Cohort-based association study of germline genetic variants with acute and chronic health complications of childhood cancer and its treatment: Genetic Risks for Childhood Cancer Complications Switzerland (GECCOS) study protocol

INTRODUCTION

Childhood cancer and its treatment may lead to various health complications. Related impairment in quality of life, excess in deaths and accumulated healthcare costs are relevant. Genetic variations are suggested to contribute to the wide inter-individual variability of complications but have been used only rarely to risk-stratify treatment and follow-up care. This study aims to identify germline genetic variants associated with acute and late complications of childhood cancer.

METHODS AND ANALYSIS

The Genetic Risks for Childhood Cancer Complications Switzerland (GECCOS) study is a nationwide cohort study. Eligible are patients and survivors who were diagnosed with childhood cancers or Langerhans cell histiocytosis before age 21 years, were registered in the Swiss Childhood Cancer Registry (SCCR) since 1976 and have consented to the Paediatric Biobank for Research in Haematology and Oncology, Geneva, host of the national Germline DNA Biobank Switzerland for Childhood Cancer and Blood Disorders (BISKIDS).GECCOS uses demographic and clinical data from the SCCR and the associated Swiss Childhood Cancer Survivor Study. Clinical outcome data consists of organ function testing, health conditions diagnosed by physicians, second primary neoplasms and self-reported information from participants. Germline genetic samples and sequencing data are collected in BISKIDS. We will perform association analyses using primarily whole-exome or whole-genome sequencing to identify genetic variants associated with specified health conditions. We will use clustering and machine-learning techniques and assess multiple health conditions in different models.

DISCUSSION

GECCOS will improve knowledge of germline genetic variants associated with childhood cancer-associated health conditions and help to further individualise cancer treatment and follow-up care, potentially resulting in improved efficacy and reduced side effects.

ETHICS AND DISSEMINATION

The Geneva Cantonal Commission for Research Ethics has approved the GECCOS study.Research findings will be disseminated through national and international conferences, publications in peer-reviewed journals and in lay language online.

Employment status and occupational positions of childhood cancer survivors from Denmark, Finland and Sweden: A Nordic register-based cohort study from the SALiCCS research programme

BACKGROUND

A childhood cancer diagnosis and late effects of treatment may affect survivors' possibilities of employment or highly skilled occupations later in life. In this study, we compared the employment and occupational status of childhood cancer survivors with population comparisons and siblings.

METHODS

In a cohort study based on Nordic registers, we identified 10 461 survivors of childhood cancer diagnosed before age 20 years in Denmark, Finland and Sweden since 1971. Survivors were compared with 48 928 population comparisons matched to survivors by age, sex and geographical region and 12 605 siblings of survivors. Annual outcome information on employment, unemployment, health-related unemployment and occupational position was obtained from the statistical institutes between 1980-2017 and assessed in multivariate logistic regression analyses from age 30 onwards.

FINDINGS

By 30 years of age, 9.2% (95% CI, 8.6-9.9%) of survivors were unemployed for health reasons. Childhood cancer survivors had considerably higher odds of health-related unemployment at ages 30, 40 and 50 than population comparisons (OR_age30, 2.57; 95% CI, 2.35-2.81) and siblings (OR_age30, 2.50; 95% CI, 2.15-2.90). We observed no large difference in unemployment unrelated to health or in occupational position. Health-related unemployment was particularly pronounced among survivors of central nervous system tumours and survivors diagnosed below 15 years of age.

INTERPRETATION

Survivors at risk of health-related unemployment should be offered comprehensive survivorship care and interventions for obtaining and maintaining suitable employment.

Cohort Profile: The Socioeconomic Consequences in Adult Life After Childhood Cancer in Scandinavia (SALiCCS) Research Programme

INTRODUCTION

The growing number of survivors of childhood cancer, with many years of life ahead, demonstrates the increasing clinical and public health relevance of investigating the risks of social and socioeconomic impairment after a childhood cancer diagnosis and the life-saving treatment. To enrich understanding of the mental, social and socioeconomic difficulties that childhood cancer survivors may face during their life-course, identify particularly vulnerable survivors and overcome the limitations of previous research, we initiated the Socioeconomic Consequences in Adult Life after Childhood Cancer in Scandinavia (SALiCCS) research programme.

METHODS

This Nordic cross-border research programme is a collaboration between the Danish Cancer Society, the Finnish Cancer Registry and Karolinska Institutet to investigate a broad range of mental, social and socioeconomic conditions in long-term childhood cancer survivors in Denmark, Finland and Sweden. SALiCCS is based on a registry-based matched cohort design, comprising five-year survivors of cancer diagnosed at ages 0-19 years (1971-2008 in Denmark, 1971-2009 in Finland, 1971-2011 in Sweden), age-, sex- and country-matched population comparisons and sibling comparisons who were followed over time. Outcomes of interest included mental disorders, educational achievements, employment and profession, family life and the need of social security benefits. Individual-level data linkage among various national registries provided the data for the research programme.

RESULTS

The SALiCCS core population comprises 21,292 five-year survivors, 103,303 population comparisons and 29,644 siblings as a second comparison group. The most common diagnoses in survivors were central nervous system tumours, leukaemias and lymphomas.

DISCUSSION

SALiCCS is the largest, most comprehensive population-based research initiative in this field, based on high-quality registry data with minimal risk of bias. The findings will be informative for evidence-based survivorship care targeting not only somatic late effects but also psychosocial impairments.

Predictors for participation in DNA self-sampling of childhood cancer survivors in Switzerland

BACKGROUND

Research on germline genetic variants relies on enough eligible participants which is difficult to achieve for rare diseases such as childhood cancer. With self-collection kits, participants can contribute genetic samples conveniently from their home. Demographic and clinical factors were identified previously that influenced participation in mailed self-collection. People with pre-existing heritable diagnoses might participate differently in germline DNA collection which might render sampling biased in this group. In this nationwide cross-sectional study, we analysed predictive factors of participation in DNA self-collection including heritable diagnoses.

METHODS

We identified childhood cancer survivors from the Swiss Childhood Cancer Registry for invitation to germline DNA self-sampling in September 2019. Participants received saliva sampling kits by postal mail at their home, were asked to fill them, sign an informed consent, and send them back by mail. Two reminders were sent to non-participants by mail. We compared demographic, clinical, and treatment information of participants with non-participants using univariable and multivariable logistic regression models.

RESULTS

We invited 928 childhood cancer survivors in Switzerland with a median age of 26.5 years (interquartile range 19-37), of which 463 (50%) participated. After the initial send out of the sampling kit, 291 (63%) had participated, while reminder letters led to 172 additional participants (37%). Foreign nationality (odds ratio [OR] 0.5; 95%-confidence interval [CI] 0.4-0.7), survivors aged 30-39 years at study versus other age groups (OR 0.5; CI 0.4-0.8), and survivors with a known cancer predisposition syndrome (OR 0.5; CI 0.3-1.0) were less likely to participate in germline DNA collection. Survivors with a second primary neoplasm (OR 1.9; CI 1.0-3.8) or those living in a French or Italian speaking region (OR 1.3; CI 1.0-1.8) tended to participate more.

CONCLUSIONS

We showed that half of childhood cancer survivors participated in germline DNA self-sampling relying completely on mailing of sample kits. Written reminders increased the response by about one third. More targeted recruitment strategies may be advocated for people of foreign nationality, aged 30-39 years, and those with cancer predisposition syndromes. Perceptions of genetic research and potential barriers to participation of survivors need to be better understood.

The European multistakeholder PanCareFollowUp project: novel, person-centred survivorship care to improve care quality, effectiveness, cost-effectiveness and accessibility for cancer survivors and caregivers

BACKGROUND

The majority of childhood cancer survivors are at risk of treatment-related adverse health outcomes. Survivorship care to mitigate these late effects is endorsed, but it is not available for many adult survivors of childhood cancer in Europe. The PanCareFollowUp project was initiated to improve their health and quality of life (QoL) by facilitating person-centred survivorship care.

METHODS

The PanCareFollowUp consortium was established in 2018, consisting of 14 project partners from ten European countries, including survivor representatives. The consortium will develop two PanCareFollowUp Interventions, including a person-centred guideline-based model of care (Care Intervention) and eHealth lifestyle coaching (Lifestyle Intervention). Their development will be informed by several qualitative studies and systematic reviews on barriers and facilitators for implementation and needs and preferences of healthcare providers (HCPs) and survivors. Implementation of the PanCareFollowUp Care Intervention as usual care will be evaluated prospectively among 800 survivors from Belgium, Czech Republic, Italy and Sweden for survivor empowerment, detection of adverse health conditions, satisfaction among survivors and HCPs, cost-effectiveness and feasibility. The feasibility of the PanCareFollowUp Lifestyle Intervention will be evaluated in the Netherlands among 60 survivors.

RESULTS

Replication manuals, allowing for replication of the PanCareFollowUp Care and Lifestyle Intervention, will be published and made freely available after the project. Moreover, results of the corresponding studies are expected within the next five years.

CONCLUSIONS

The PanCareFollowUp project is a novel European collaboration aiming to improve the health and QoL of all survivors across Europe by developing and prospectively evaluating the person-centred PanCareFollowUp Care and Lifestyle Interventions.

Dietary Intake and Diet Quality of Adult Survivors of Childhood Cancer and the General Population: Results from the SCCSS-Nutrition Study

Childhood cancer survivors (CCSs) are at increased risk of developing chronic health conditions. This may potentially be reduced by a balanced diet. We aimed to compare dietary intake and diet quality using the Alternative Healthy Eating Index (AHEI) of adult CCSs and the general Swiss population. A food frequency questionnaire (FFQ) was completed by CCSs with a median age of 34 (IQR: 29-40) years. We compared dietary intake of 775 CCSs to two population-based cohorts who completed the same FFQ: 1276 CoLaus and 2529 Bus Santé study participants. CCSs consumed particular inadequate amounts of fiber and excessive amounts of sodium and saturated fat. Dietary intake was similar in CCSs and the general population. The mean AHEI was low with 49.8 in CCSs (men: 47.7, women: 51.9), 52.3 in CoLaus (men: 50.2, women: 54.0), and 53.7 in Bus Santé (men: 51.8, women: 54.4) out of a maximum score of 110. The AHEI scores for fish, fruit, vegetables, and alcohol were worse in CCSs than in the general population, whereas the score for sugar-sweetened beverages was better (all p < 0.001). Diet quality at follow-up did not differ between clinical characteristics of CCSs. Long-term CCSs and the general population have poor dietary intake and quality in Switzerland, which suggests similar population-based interventions for everyone.

Hospital Contacts for Psychiatric Disorders in Parents of Children With Cancer in Denmark

Background

Having a child diagnosed with cancer is a devastating experience that may affect parents' mental health. We aimed to assess the risk of hospital contacts for psychiatric disorders in parents of children with cancer.

Methods

We conducted a nationwide population-based cohort study using Danish registry data. Parents of children diagnosed with cancer between 1982 and 2014 (n = 6689 mothers, n = 5509 fathers) were matched with comparison parents of cancer-free children (n = 67 544 mothers, n = 55 756 fathers). We used Cox proportional hazards models to estimate the risk of hospital contacts for any psychiatric disorder and specific disorders. Cox models were also used to investigate sociodemographic and cancer-related risk factors for psychiatric disorders.

Results

Incidence rates of hospital contacts for any psychiatric disorder were 426 per 100 000 person-years in mothers of children with cancer and 345 per 100 000 person-years in comparison mothers. For fathers, the respective incidence rates were 260 and 262 cases per 100 000 person-years. Compared with parents of cancer-free children, mothers of children with cancer were at an increased risk of hospital contacts for any psychiatric disorder (hazard ratio = 1.23, 95% confidence interval = 1.12 to 1.36), whereas no elevated risk was seen in fathers (hazard ratio = 0.99, 95% confidence interval = 0.87 to 1.13). Among mothers, risks were particularly elevated for affective and stress-related disorders. Parents of deceased children and children diagnosed at a younger age were at particular risk of hospital contacts for psychiatric disorders.

Conclusion

Hospital contacts for psychiatric disorders were overall rare. Health-care professionals should draw attention to subgroups of vulnerable parents to meet their needs of support and adequate treatment.

Post-traumatic stress in parents of long-term childhood cancer survivors compared to parents of the Swiss general population

BACKGROUND

We describe post-traumatic stress symptoms (PTSS) and post-traumatic stress disorder (PTSD) in parents of long-term childhood cancer survivors (CCS-parents) and compare them to parents of similar-aged children (comparison-parents) of the Swiss general population (SGP). We compare type of reported stressful event, prevalence of PTSS and PTSD, and psychosocial and cancer-related characteristics associated with PTSS. We further describe the respective normative data for the SGP.

METHODS

We conducted a nationwide cross-sectional questionnaire survey in a population-based sample of long-term CCS-parents (survivors aged ≤16 years at diagnosis, ≥20 years at study, >5 years post-diagnosis) and in the SGP. Using the Impact of Event Scale-Revised, we measured PTSS regarding the most stressful event experienced, and computed probable cases of PTSD.

RESULTS

Participants included 663 CCS-parents (39.4% fathers) and 1035 individuals of the SGP (40.0% male), of which we identified 391 comparison-parents (41.2% fathers). Illness was most often indicated as stressful event (CCS-parents: 49.5%, comparison-parents: 27.6%, SGP: 25.3%). Prevalence of PTSS and PTSD (CCS-parents: 4.8%, comparison-parents: 6.7%, SGP: 5.6%) did not significantly differ. Lower education was associated with higher intrusion, avoidance, and hyperarousal in all samples (all P ≤ .003). Parents of children with a chronic illness reported higher intrusion (all P ≤ .004). We found no associations with cancer-related characteristics.

CONCLUSIONS

No increased risk for PTSS or PTSD was found among CCS-parents. Individuals with lower education and those with a chronically ill child might benefit from additional support to help manage and resolve the stress symptoms in the long term.

The impact of childhood cancer on parental separation, divorce, and family planning in Denmark

BACKGROUND

Childhood cancer is a devastating experience for the family. The objective of the current study was to assess the impact of having a child with cancer on parental separation, divorce, and future family planning among families residing in Denmark.

METHODS

The authors conducted a nationwide cohort study using Danish registry data. Parents of children diagnosed with cancer between 1982 and 2014 (7066 children and 12,418 case parents) were matched with 10 comparison parents of cancer-free children per case parent (69,993 children and 125,014 comparison parents). We used discrete-time Cox regression models to compare the risk of separation (end of cohabitation) and divorce between case and comparison parents, and to identify risk factors for separation and divorce among case parents only. Descriptive statistics were used to compare family planning between case and comparison parents.

RESULTS

Case parents were found to have a slightly lower risk of separation (hazard ratio, 0.96; 95% confidence interval, 0.93-0.99) and divorce (hazard ratio, 0.92; 95% confidence interval, 0.87-0.97) than comparison parents. The authors found that case parents who were aged <45 years, with short education (an International Standard Classification of Education code indicating early childhood education, primary education, and lower secondary education), and who were unemployed were at an increased risk of separation and divorce. Moreover, the parents of children diagnosed with cancer at a young age (aged <15 years) were more likely to separate or divorce. No differences with regard to the total number of children and time to a next child after the cancer diagnosis were observed between case and comparison parents.

CONCLUSIONS

Having a child with cancer was not associated with an overall adverse impact on parents' risk of separation or divorce and future family planning. These encouraging findings should be communicated to parents to support them along their child's cancer trajectory.

Childhood cancer: Survival, treatment modalities, late effects and improvements over time

Since the 1960s, paediatric oncologists have gradually become better organised in large study groups and participation in clinical trials is today considered as the standard of care, with most children with cancer in Europe and North America being enrolled on available treatment protocols. Chemotherapy is nowadays the main element of therapy, but irradiation is still required for some patients. With the advent of multimodality therapy and supportive care, five-year cancer survival exceeds 80 % in most European and North American countries today. The substantial improvements in survival led to a constantly growing population of childhood cancer survivors. Concerns regarding the risk of late effects of the intensive cancer treatment at a young age, together with increasing numbers of survivors, have directed attention towards survivorship research. Survivors of childhood cancer are at longstanding risk of various severe somatic and mental health conditions attributable to the cancer and its treatment, as well as adverse social and socioeconomic consequences, and diminished psychological well-being and quality of life. It is, however, important to stress that some survivors have no or very mild adverse health conditions. Nevertheless, joint efforts are warranted for the care and long-term follow-up of childhood cancer patients. With this article, we provide a comprehensive overview of improvements in survival and treatment modalities over time, as well as the related somatic and mental late effects, and social and socioeconomic difficulties that these children might encounter later in life.

"I wish someone had once asked me how I'm doing": Disadvantages and support needs faced by parents of long-term childhood cancer survivors

BACKGROUND

Childhood cancer affects the whole family and can have a lasting impact on parents of childhood cancer survivors (CCS). We aimed to (1) describe parents' perspective of currently experienced disadvantages and of their support needs during treatment, after treatment, and today; (2) identify characteristics associated with disadvantages and support needs; and (3) describe the use of existing support services.

PROCEDURE

In this population-based study, we identified parents of CCS (diagnosed ≤16 years of age, ≥5 years since diagnosis, aged ≥20 years at study) through the Swiss Childhood Cancer Registry (SCCR). Parents completed a questionnaire on perceived disadvantages (e.g., job-related, financial, etc.), support needs (e.g., job-related, financial, etc.), and socio-demographics. Cancer-related characteristics were available from the SCCR. We used multivariable multilevel logistic regression to identify characteristics associated with disadvantages and support needs.

RESULTS

An average of 24 years after diagnosis, one-fifth of parents (n = 59/308; 19.2%) reported disadvantages, and 7.1% reported support needs. Many parents had desired more support during (66.9%) or after (34.4%) their child's cancer treatment. Parents whose child experienced late effects (OR = 26.6; 95% CI, 2.9-241.0) or was dependent on parents (OR = 10.6; 95% CI, 2.1-53.7) reported greater current need for more support. Almost half of parents (43.5%) reported having used existing support services.

CONCLUSIONS

Many parents need more support during and after active treatment of their child's cancer, and some experience support needs and disadvantages long into survivorship. Better promotion of existing services for parental and familial support and setting up new services, where needed, may help parents in the long term.

Health-related quality of life in Switzerland: normative data for the SF-36v2 questionnaire

Purpose

Health-related quality of life (HRQOL) is an important concept to describe well-being of the general population and persons with diseases. The short form-36 (SF-36) is a widely used questionnaire assessing self-reported HRQOL in eight health domains. The aims of this study were to provide normative data for the SF-36 version 2 (SF-36v2) for all language regions in Switzerland and weighting coefficients to calculate two summary measures for physical and mental health.

Methods

A random representative (regarding age, sex, and language region) sample of people living in Switzerland aged 18–75 years in 2015 was eligible for our questionnaire survey. We calculated the eight health domain subscales for different subsamples based on sociodemographic characteristics. Two summary measures for physical and mental health were derived using data-based factor score coefficients and calculated for the subsamples.

Results

A total of 1209 persons completed the SF-36v2 (mean age 48.7 years, 58.1% women). The SF-36v2 was valid and reliable in Switzerland. Physical health was better in men (p = 0.012) and younger persons (p < 0.001). Mental health was better in men (p < 0.001) and older persons (p < 0.001). Regarding regional differences, we found better physical (p = 0.002) and mental (p < 0.001) health in German speaking persons compared to French and Italian speaking persons.

Conclusions

This paper presents the first SF-36v2 normative data for Switzerland, which are based on a recent study in a representative sample. Our normative data and weighting coefficients will enable future studies to compare HRQOL assessed by the SF-36 in healthy and diseased persons to a representative Swiss sample.

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.

Relationship status and quality of the partner relationship in parents of long-term childhood cancer survivors: The Swiss Childhood Cancer Survivor Study-Parents

OBJECTIVE

The intensive and long-lasting experience of childhood cancer is a tremendous stressor for the parental relationship. We aimed to (1) compare civil status and partner relationship of parents of long-term childhood cancer survivors with population-based comparisons, (2) identify cancer-related characteristics associated with not being married, and (3) evaluate the quality of the partner relationship.

METHODS

We sent questionnaires to parents of survivors aged ≤16 years at diagnosis and ≥20 years at study. Population-based comparisons were derived from a random sample of the general population (≥1 child aged ≥20 years) and standardized by sociodemographic characteristics of survivor parents. We used logistic regression to identify cancer-related characteristics associated with not being married. The quality of the partner relationship was evaluated using the relationship-specific attachment scale for adults assessing the dimensions security (secure-fearful) and dependency (dependent-independent).

RESULTS

A total of 784 parents (58.9% mothers) of 512 survivors (response rate: 44.0%) and 471 comparison parents completed the questionnaire. Parents of survivors were less often divorced/separated (9.0% vs 17.5%, P < 0.001) and more often in a partner relationship (89.9% vs 85.0%, P = 0.010) than comparisons. Not being married was not associated with cancer-related characteristics. Parents of survivors reported similar security (P = 0.444) but higher dependency (P = 0.032) within the partner relationship than comparisons. In both populations, fathers indicated higher security and dependency than mothers.

CONCLUSIONS

Long after the diagnosis of cancer in their child, parents' relationship appears similar as in parents of the general population. The increased dependency reported by parents of survivors suggests that they managed their child's disease as a team.

Surviving childhood cancer: a systematic review of studies on risk and determinants of adverse socioeconomic outcomes

Substantial improvements in childhood cancer survival have resulted in a steadily increasing population of childhood cancer survivors. Whereas somatic late effects have been assessed in many studies, less is known about the impact of childhood cancer on socioeconomic outcomes in survivors. The aim of this article was to evaluate and summarise the evidence on the socioeconomic conditions of childhood cancer survivors and to identify survivors at particular risk of adverse socioeconomic outcomes. An extensive literature search of three electronic databases was conducted. Of 419 articles identified, 52 met the inclusion criteria. All the selected articles were appraised for quality, and findings were summarised in a narrative synthesis. Childhood cancer survivors were at higher risk of adverse socioeconomic outcomes with regard to educational achievement, income and social security benefits than the general population or a sibling comparison group. The risks for unemployment and a lower occupational position were significantly increased only for survivors of a central nervous system tumour. Notably, survivors of central nervous system tumours, survivors treated with cranial radiotherapy and those diagnosed at younger age independent of cancer type were determinants of particular adverse socioeconomic outcomes. Given the increasing population of childhood cancer survivors, targeted follow-up interventions and support strategies addressing not only the somatic and psychiatric late effects but also the socioeconomic difficulties that some childhood cancer survivors face is of high importance to reduce social inequity, and ensure a high quality of life after childhood cancer.

Attendance to Follow-Up Care in Survivors of Adolescent and Young Adult Cancer: Application of the Theory of Planned Behavior

PURPOSE

The aim was to study follow-up care attendance in adolescent and young adult (AYA) cancer survivors to investigate: (1) correlates of the intention to attend follow-up care and (2) whether the intention is associated with the actual attendance, applying the theory of planned behavior (TPB).

METHODS

We conducted a questionnaire survey in AYA cancer survivors diagnosed 1990-2005 at age 16-25 years, registered in the Cancer Registry Zurich and Zug, Switzerland, who had survived at least 5 years. Structural equation modeling was applied to investigate TPB-related correlates (attitudes, subjective norms, and perceived behavioral control) of intention to attend follow-up care. Logistic regression analysis was used to study the association between intention and actual attendance.

RESULTS

We included 160 AYA cancer survivors in the study (mean age at study: 34.0 years, mean age at diagnosis: 21.6 years, 98 [61.3%] male). Positive attitudes toward follow-up care (coefficient = 0.32, 95% confidence interval [CI]: 0.05 to 0.60) and supportive subjective norms (coefficient = 0.59, 95% CI: 0.41 to 0.78) were associated with higher intention to attend follow-up care. Perceived behavioral control was not associated with intention to attend (coefficient = -0.13, 95% CI: -0.36 to 0.10), but with actual attendance (odds ratio [OR] = 4.55, 95% CI: 1.83 to 11.31). Higher intention was associated with actual follow-up care attendance (OR = 14.29, 95% CI: 5.80 to 35.21).

CONCLUSION

Positive attitudes and supportive social norms were associated with higher intention to attend follow-up care, and higher intention was associated with actual follow-up care attendance. Increasing awareness of the importance and benefits of follow-up care not only among survivors but also family, friends and healthcare professionals may help increase follow-up care attendance among AYA cancer survivors.

Can the theory of planned behavior help explain attendance to follow-up care of childhood cancer survivors?

OBJECTIVE

Childhood cancer survivors are at high risk for late effects. Regular attendance to long-term follow-up care is recommended and helps monitoring survivors' health. Using the theory of planned behavior, we aimed to (1) investigate the predictors of the intention to attend follow-up care, and (2) examine the associations between perceived control and behavioral intention with actual follow-up care attendance in Swiss childhood cancer survivors.

METHODS

We conducted a questionnaire survey in Swiss childhood cancer survivors (diagnosed with cancer aged <16 years between 1990 and 2005; ≥5 years since diagnosis). We assessed theory of planned behavior-related predictors (attitude, subjective norm, perceived control), intention to attend follow-up care, and actual attendance. We applied structural equation modeling to investigate predictors of intention, and logistic regression models to study the association between intention and actual attendance.

RESULTS

Of 299 responders (166 [55.5%] females), 145 (48.5%) reported attending follow-up care. We found that subjective norm, ie, survivors' perceived social pressure and support (coef = 0.90, P < 0.001), predicted the intention to attend follow-up; attitude and perceived control did not. Perceived control (OR = 1.58, 95%CI:1.04-2.41) and intention to attend follow-up (OR = 6.43, 95%CI:4.21-9.81) were positively associated with attendance.

CONCLUSIONS

To increase attendance, an effort should be made to sensitize partners, friends, parents, and health care professionals on their important role in supporting survivors regarding follow-up care. Additionally, interventions promoting personal control over the follow-up attendance might further increase regular attendance.

Household income and risk-of-poverty of parents of long-term childhood cancer survivors

BACKGROUND

Taking care of children diagnosed with cancer affects parents' professional life and may place the family at risk-of-poverty. We aimed to (i) compare the household income and risk-of-poverty of parents of childhood cancer survivors (CCS) to parents of the general population, and (ii) identify sociodemographic and cancer-related factors associated with risk-of-poverty.

METHODS

As part of the Swiss Childhood Cancer Survivor Study, we sent a questionnaire to parents of CCS aged 5-15 years, who survived ≥5 years after diagnosis. Information on parents of the general population came from the Swiss Household Panel (parents with ≥1 child aged 5-15 years). Risk-of-poverty was defined as having a monthly household income of <4,500 Swiss Francs (CHF) for single parents and <6,000 CHF for parent-couples. We used logistic regression to identify factors associated with risk-of-poverty.

RESULTS

We included parents of 383 CCS and 769 control parent households. Parent-couples of CCS had a lower household income (P_trend < 0.001) and were at higher risk-of-poverty (30.4% vs. 19.3%, P = 0.001) compared to control parent-couples. Household income and risk-of-poverty of single parents of CCS was similar to control single parents. Parents of CCS were at higher risk-of-poverty if they had only standard education (OR_mother = 3.77 [where OR is odds ratio], confidence interval [CI]: 1.61-8.82; OR_father = 8.59, CI: 4.16-17.72) and were from the German language region (OR = 1.99, CI: 1.13-3.50). We found no cancer-related risk factors.

CONCLUSION

Parents of long-term CCS reported lower household income and higher risk-of-poverty than control parents. Support strategies may be developed to mitigate parents' risk-of-poverty in the long term, particularly among parents with lower education.

Physicians' experience with follow-up care of childhood cancer survivors - challenges and needs

BACKGROUND

Regular follow-up care is essential for childhood cancer survivors, but we know little about physicians' experience with it. We aimed to describe: (1) involvement of Swiss physicians in follow-up care; (2) content of follow-up care provided; (3) problems encountered; and (4) additional resources needed.

MATERIALS AND METHODS

Within this cross-sectional survey we sent adapted questionnaires via professional associations to a sample of medical oncologists (MOs), paediatric oncologists (POs), general practitioners (GPs) and paediatricians (P) in Switzerland. Only oncologists involved in follow-up care were asked to report problems. GPs and Ps not involved in follow-up could indicate why. All physicians were asked about the content of follow-up care provided and additional resources needed.

RESULTS

A total of 183 physicians responded (27 MO, 13 PO, 122 GP, 21 P). Involved in follow-up were 81% of MOs, 85% of POs, 39% of GPs and 81% of Ps. Follow-up content differed between oncologists (MO and PO) and generalists (GP and P), with generalists examining or informing less in regard to the former cancer. POs reported more problems than MOs: many POs reported problems with transition of survivors to adult care (91%), and because of financial resources (73%) and time restraints (73%). MOs reported most problems during transition (23%). Not being aware of a survivor was the most common reason for GPs and Ps not participating in follow-up (74%). All groups reported a need for standardised protocols (85-91%) and specialised training (55-73%). GPs (94%) and Ps (100%) additionally desired more support from oncologists.

CONCLUSIONS

To improve quality and efficiency of follow-up care a national follow-up care model including standardised protocols and guidelines needs to be developed.

Education, employment and marriage in long-term survivors of teenage and young adult cancer compared with healthy controls

QUESTIONS UNDER STUDY

Teenage and young adult (TYA) cancer patients are faced with the diagnosis during a challenging period of psychosocial development that may affect social outcomes in the long term. Therefore, we aimed to: (1) determine differences in social outcomes between long-term TYA cancer survivors and healthy controls and (2) identify factors associated with adverse social outcomes.

METHODS

We sent a questionnaire to TYA cancer survivors (aged 16-25 years at diagnosis, 5 years after diagnosis) registered in the Cancer Registry Zurich and Zug. Information on controls was obtained from the Swiss Health Survey 2012. We assessed educational achievement, employment status, marital status and life partnership (survivors only), and compared these outcomes between survivors and controls. We used logistic regression to identify sociodemographic and cancer-related factors associated with social outcomes.

RESULTS

We included 160 TYA cancer survivors and 999 controls. Educational achievement of survivors differed significantly from controls (p = 0.012): more survivors than controls reported upper secondary education (33 vs 27%) and fewer survivors reported university education (12 vs 21%). No significant differences were found for employment (p = 0.515) and marital status (p = 0.357). The majority of survivors (91%) and controls (90%) were employed, and 37% of survivors were married, compared with 41% of controls. There were no cancer-related factors associated with having only basic education. Unemployment was associated with younger age at diagnosis (odds ratio [OR] 5.3, 95% confidence interval [CI] 1.3-30.8) and self-reported late effects (OR 4.7, 95% CI 1.3-19.5). Survivors of younger age at diagnosis were more likely not to be married (OR 2.7, 95% CI 1.3-5.7) and not to have a life partner (OR 2.3, 95% CI 1.0-5.2).

CONCLUSIONS

Our findings indicate that TYA cancer survivors completed applied higher education rather than a university education. Future studies including larger samples of TYA cancer survivors are needed to validate our findings and to explore the reasons for and satisfaction with the observed educational pathway.

Using the refined ICF Linking Rules to compare the content of existing instruments and assessments: a systematic review and exemplary analysis of instruments measuring participation

BACKGROUND

Existing instruments measuring participation may vary with respect to various aspects. This study aimed to examine the comparability of existing instruments measuring participation based on the International Classification of Functioning, Disability and Health (ICF) by considering aspects of content, the perspective adopted and the categorization of response options.

METHODS

A systematic literature review was conducted to identify instruments that have been commonly used to measure participation. Concepts of identified instruments were then linked to the ICF following the refined ICF Linking Rules. Aspects of content, perspective adopted and categorization of response options were documented.

RESULTS

Out of 315 instruments identified in the full-text screening, 41 instruments were included. Concepts of six instruments were linked entirely to the ICF component Activities and Participation; of 10 instruments still 80% of their concepts. A descriptive perspective was adopted in most items across instruments (75%), mostly in combination with an intensity rating. An appraisal perspective was found in 18% and questions from a need or dependency perspective were least frequent (7%).

CONCLUSION

Accounting for aspects of content, perspective and categorization of responses in the linking of instruments to the ICF provides detailed information for the comparison of instruments and guidance on narrowing down the choices of suitable instruments from a content point of view. Implications for Rehabilitation For clinicians and researchers who need to identify a specific instrument for a given purpose, the findings of this review can serve as a screening tool for instruments measuring participation in terms of the following: • Their content covered based on the ICF. • The perspective adopted in the instrument (e.g., descriptive, need/dependency or appraisal). • The categorization of their response options (e.g., intensity or frequency).

Employment Situation of Parents of Long-Term Childhood Cancer Survivors

BACKGROUND

Taking care of children diagnosed with cancer affects parents' professional life. The impact in the long-term however, is not clear. We aimed to compare the employment situation of parents of long-term childhood cancer survivors with control parents of the general population, and to identify clinical and socio-demographic factors associated with parental employment.

METHODS

As part of the Swiss Childhood Cancer Survivor Study, we sent a questionnaire to parents of survivors aged 5-15 years, who survived ≥5 years after diagnosis. Information on control parents of the general population came from the Swiss Health Survey (restricted to men and women with ≥1 child aged 5-15 years). Employment was categorized as not employed, part-time, and full-time employed. We used generalized ordered logistic regression to determine associations with clinical and socio-demographic factors. Clinical data was available from the Swiss Childhood Cancer Registry.

RESULTS

We included 394 parent-couples of survivors and 3'341 control parents (1'731 mothers; 1'610 fathers). Mothers of survivors were more often not employed (29% versus 22%; ptrend = 0.007). However, no differences between mothers were found in multivariable analysis. Fathers of survivors were more often employed full-time (93% versus 87%; ptrend = 0.002), which remained significant in multivariable analysis. Among parents of survivors, mothers with tertiary education (OR = 2.40, CI:1.14-5.07) were more likely to be employed. Having a migration background (OR = 3.63, CI: 1.71-7.71) increased the likelihood of being full-time employed in mothers of survivors. Less likely to be employed were mothers of survivors diagnosed with lymphoma (OR = 0.31, CI:0.13-0.73) and >2 children (OR = 0.48, CI:0.30-0.75); and fathers of survivors who had had a relapse (OR = 0.13, CI:0.04-0.36).

CONCLUSION

Employment situation of parents of long-term survivors reflected the more traditional parenting roles. Specific support for parents with low education, additional children, and whose child had a more severe cancer disease could improve their long-term employment situation.

Mortality and longevity after a spinal cord injury: systematic review and meta-analysis

BACKGROUND/AIMS

Mortality and longevity studies of spinal cord injury (SCI) are essential for informing healthcare systems and policies. This review evaluates the current evidence among people with SCIs worldwide in relation to the WHO region and country income level; demographic and lesion characteristics; and in comparison with the general population.

METHODS

A systematic review of relevant databases for original studies. Pooled estimates were derived using random effects meta-analysis, restricted to traumatic SCI.

RESULTS

Seventy-four studies were included. In-hospital mortality varied, with pooled estimates of 24.1% (95% confidence interval (CI) 14.1-38.0), 7.6% (95% CI 6.3-9.0), 7.0% (95% CI 1.5-27.4), and 2.1% (95% CI 0.9-5.0) in the WHO regions of Africa, the Americas, Europe and Western Pacific. The combined estimate for low- and middle-income countries was nearly three times higher than for high-income countries. Pooled estimates of first-year survival were 86.5% (95% CI 75.3-93.1), 95.6% (95% CI 81.0-99.1), and 94.0% (95% CI 93.3-94.6) in the Americas, Europe and Western Pacific. Pooled estimates of standardized mortality ratios in tetraplegics were 2.53 (2.00-3.21) and 2.07 (1.47-2.92) in paraplegics.

CONCLUSION

This study found substantial variation in mortality and longevity within the SCI population, compared to the general population, and between WHO regions and country income level. Improved standardization and quality of reporting is needed to improve inferences regarding the extent to which mortality outcomes following an SCI are related to healthcare systems, services and policies.

Effects of sexual and physical abuse: a comparison of adolescent inpatients

The present study was designed to collect descriptive data on a sample of hospitalized adolescents who were victims of sexual and/or physical abuse and to compare these groups to patients without a history of abuse. A questionnaire was administered to 51 inpatient teenagers at Fort Logan Mental Health Center, a state psychiatric hospital in Denver, Colorado. Information was obtained about family background, type, extent and duration of abuse, drug and alcohol abuse and self-reported mental health and general adjustment problems. In addition, clinical staff completed the Revised Behavior Problem Checklist (1) for the subjects. The results indicated statistically significant differences (p less than .05) between groups with adolescents who were both physically and sexually abused reporting the most problems. The implications for the findings for treatment are discussed.
