Developing strategies for long term follow up of survivors of childhood cancer

The integration of primary care and childhood cancer survivorship care: a scoping review

PURPOSE

This scoping review describes existing care models that integrate primary care and childhood cancer survivorship care, examines the effectiveness of these models, and characterizes barriers and facilitators to their integration.

METHODS

A systematic search (PubMed®, CINAHL®, Embase®) was conducted to identify citations which were evaluated against inclusion criteria using the PICOTTS framework. The PRISMA-ScR extension for scoping reviews was used to report review findings (protocol https://osf.io/92xbg ).

RESULTS

Twenty-three studies were included. Three care models integrating primary care and childhood cancer survivorship care were identified: consultative shared care in a primary care setting (N = 3); longitudinal shared care (N = 2); and PCP-led care employing a survivorship care plan (N = 5). While many described risk-adapted care, few used risk stratification approaches to inform care. Measures of model effectiveness varied, with discrepant findings regarding late effects detection in PCP-led approaches. The most frequently cited barriers and facilitators reflected provider- and system-level factors (PCP knowledge/experience identified as greatest barrier (N = 11); clinical information from oncologist identified as greatest facilitator (N = 9)).

CONCLUSIONS

Identified models depended on PCP knowledge and healthcare system coordination, and studies suggested the need for strong oncologic involvement in follow-up care. Improved training for PCPs and the coordinated transfer of clinical information could facilitate their involvement in such care. Overall, standardized measures of effectiveness are needed to deliver optimal childhood cancer survivorship care.

IMPLICATIONS FOR CANCER SURVIVORS

The literature revealed three care models defined by SCP use, provider involvement, and continuity of care, with several studies recommending oncologic involvement in follow-up care for high-risk survivors.

The cumulative burden of self-reported, clinically relevant outcomes in long-term childhood cancer survivors and implications for survivorship care: A DCCSS LATER study

BACKGROUND

The aim of this study is to evaluate how cumulative burden of clinically relevant, self-reported outcomes in childhood cancer survivors (CCSs) compares to a sibling control group and to explore how the burden corresponds to levels of care proposed by existing risk stratifications.

METHODS

The authors invited 5925 5-year survivors from the Dutch Childhood Cancer Survivor Study (DCCSS LATER) cohort and their 1066 siblings to complete a questionnaire on health outcomes. Health outcomes were validated by self-reported medication use or medical record review. Missing data on clinically relevant outcomes in CCSs for whom no questionnaire data were available were imputed with predictive mean matching. We calculated the mean cumulative count (MCC) for clinically relevant outcomes. Furthermore, we calculated 30-year MCC for groups of CCSs based on primary cancer diagnosis and treatment, ranked 30-year MCC, and compared the ranking to levels of care according to existing risk stratifications.

RESULTS

At median 18.5 years after 5-year survival, 46% of CCSs had at least one clinically relevant outcome. CCSs experienced 2.8 times more health conditions than siblings (30-year MCC = 0.79; 95% confidence interval [CI], 0.74-0.85 vs. 30-year MCC = 0.29; 95% CI, 0.25-0.34). CCSs' burden of clinically relevant outcomes consisted mainly of endocrine and vascular conditions and varied by primary cancer type. The ranking of the 30-year MCC often did not correspond with levels of care in existing risk stratifications.

CONCLUSIONS

CCSs experience a high cumulative burden of clinically relevant outcomes that was not completely reflected by current risk stratifications. Choices for survivorship care should extend beyond primary tumor and treatment parameters, and should consider also including CCSs' current morbidity.

Knowledge and attitude on childhood cancer survivorship among healthcare trainees: a multicentre study from India

BACKGROUND

The proportion of childhood cancer survivors (CCS) in low/middle-income countries (LMICs) is rising. CCS often develop several physical and psycho-social long-term adverse effects, with unique healthcare needs. Primary healthcare providers (primary care physicians (PCPs)), especially in LMICs, are often not equipped to handle survivorship care. This study aimed to assess knowledge, and attitude among trainee healthcare providers concerning major issues of paediatric survivorship care.

METHODS

A multi-centre, cross-sectional, questionnaire-based study was conducted among nursing and medical undergraduate students, and postgraduate medical residents across three tertiary-care teaching hospitals in India-All India Institute of Medical Sciences, New Delhi; Jawaharlal Institute of Postgraduate Medical Education and Research, Puducherry; and Maulana Azad Medical College, New Delhi. A questionnaire with total of 24 questions (14 knowledge-based and 10 attitude-based) was finalised after validation by expert review and piloting. The major domains covered in the questionnaire included knowledge and attitude regarding long-term adverse effects and psychosocial, employment-related issues faced by the survivors. It was administered to the study participants electronically. The knowledge-based questions had true/false responses (scored as 0 or 1 if incorrect or correct, respectively). Attitude-based questions were scored as 5-point Likert scale.

RESULTS

Total 898 responses were collected (median age: 21 years, 64% (576/898) female). Among the respondents, 44% were undergraduate medical students, 42% were nursing students and 14% were postgraduate medical residents. The mean (SD) of knowledge score was 8.72 (2.04) (out of 14). On multivariable analysis, only discipline of training predicted knowledge scores regarding survivorship care. Postgraduate medical residents (9.08) as well as undergraduate medical students (8.85), had significantly higher mean knowledge scores than nursing students (8.47) (p=0.004).Two questions were answered incorrectly by the majority; children and siblings of CCS need additional genetic screening (79% incorrectly answered true), and CCS face intimacy issues in relation to normal sexual functioning (59% incorrectly answered false).Nearly half (48%) of respondents believed that their knowledge of cancer survivorship issues was inadequate. Majority of respondents (84%) suggested that oncologists should handle long-term survivorship care rather than PCPs.

CONCLUSION

Trainee healthcare providers in India reported inadequate knowledge regarding survivorship care. Improving awareness by incorporating survivorship in teaching curriculum is imperative to equip future PCPs to provide survivorship care across the country.

Health Care Transitions Among Adolescents and Young Adults With Cancer

Survivors of adolescent and young adult (AYA) cancers, defined as individuals diagnosed with a primary malignancy between age 15 and 39 years, are a growing population with unique developmental, psychosocial, and health-related needs. These individuals are at excess risk of developing a wide range of chronic comorbidities compared with the general population and, therefore, require lifelong, risk-based, survivorship care to optimize long-term health outcomes. The health care needs of survivors of AYA cancers are particularly complicated given the often heterogeneous and sometimes fragmented care they receive throughout the cancer care continuum. For example, AYA survivors are often treated in disparate settings (pediatric v adult) on dissimilar protocols that include different recommendations for longitudinal follow-up. Specialized tools and techniques are needed to ensure that AYA survivors move seamlessly from acute cancer care to survivorship care and, in many cases, from pediatric to adult clinics while still remaining engaged in long-term follow-up. Systematic, age-appropriate transitional practices involving well-established clinical models of care, survivorship care plans, and survivorship guidelines are needed to facilitate effective transitions between providers. Future studies are necessary to enhance and optimize the clinical effectiveness of transition processes in AYA cancer survivors.

The impact of radiotherapy on the hypothalamo-pituitary axis: old vs new radiotherapy techniques

Multimodality cancer therapy has led to remarkable improvements in survival of childhood and young adult cancer, with survival rates exceeding 85%. Such remission rates come with their own adverse sequelea or 'late effects'. Although the cause of these late effects is multi-factorial, radiation-related adverse effects are one of the most prevalent. Hypopituitarism is a recognised complication of irradiation of brain tumours distant to the hypothalamo-pituitary (HP) axis when the axis is included within the exposed field. Much of the data concerning the development of hypopituitarism, however, relate to early forms of photon-based radiotherapy. In this narrative review, we discuss advances in individual radiotherapy techniques currently used in treating brain tumours and their theoretical benefits based primarily on dosimetric studies. Increasingly precise radiation techniques, including advances in the delivery of photons (i.e. intensity-modulated radiotherapy) and proton beam therapy, are now available options. The premise behind these newer techniques is to reduce the dose and volume of normal tissue irradiated whilst maintaining an effective radiation dose to target tissue. When treating brain tumours distant to the HP axis the expectation, based upon dosimetric studies, is that newer forms of radiotherapy will less frequently involve the HP axis in the exposed field, and where incorporated within the field it will be exposed to a lower radiotherapy dosage. Intuitively the dosimetric studies should translate into significant reductions in the prevalence of HP dysfunction. These data are promising; however, to date there are minimal robust clinical data to determine if the theoretical benefits of these newer techniques on HP dysfunction is to be realised.

Current pediatric cancer survivorship practices: a report from the Children's Oncology Group

PURPOSE

The purpose of this study is to describe current survivor services provided by COG institutions.

METHODS

A 190-question online survey was distributed to 209 COG member institutions over a 5-month period in 2017. Descriptive statistics were used to describe survivor services and explore their changes between 2007 and 2017.

RESULTS

Representatives from 153 (73%) institutions completed the survey. Of these, 96% of institutions reported that they provide pediatric cancer survivor care either in a specialized late effects program (75%) or a regular pediatric oncology clinic (24%). However, only 29.8% of institutions reported that > 75% of eligible patients were seen in a survivorship clinic. The most prevalent reported barriers to survivor care were lack of dedicated time (58%) and lack of funding for program development (41%). In 2017, 88% of institutions provided a treatment summary compared to 31% in 2007.

CONCLUSION

The majority of COG institutions have dedicated care for pediatric and young adult survivors of childhood cancer; however, at most institutions, < 75% of eligible patients access this care. Research into more efficient technology strategies is needed to ensure all survivors the opportunity to receive appropriate follow-up care.

IMPLICATIONS FOR CANCER SURVIVORS

This survey provides a snapshot of the status of late effects services within COG institutions and provides information on residual gaps in services. Next steps should focus on the importance of attendance in a survivorship clinic on the physical health and psychosocial outcomes in cancer survivors.

Chronic health conditions among long-term survivors of adolescent and young adult (AYA) cancer: A comparison of outcomes in Israel and the United States

BACKGROUND

There is a paucity of information on health outcomes of adolescent and young adult (AYA) cancer survivors living outside North America and Europe. This study compared outcomes in AYA cancer survivors in Israel with individuals without cancer and similar demographics and access to health care, and to AYA cancer survivors living in the United States.

METHODS

This study included 12,674 2-year survivors of AYA (aged 15-39 years) cancer diagnosed between 2000 and 2018 at Clalit Health Services (CHS) in Israel. CHS participants without cancer (N = 50,696) were matched 4:1 to survivors on age, sex, ethnicity, and membership duration. Poisson regression was used to determine incidence rate ratios (IRRs) for chronic conditions. The US Kaiser Permanente Southern California AYA cohort (N = 6778) was used to estimate weighted (age, sex) standardized incidence ratios (SIRs) for CHS survivors.

RESULTS

CHS AYA cancer survivors were more likely to have any chronic condition (IRR, 1.6 95% CI, 1.5-1.7), compared with participants without cancer. Survivors had an increased risk across nearly all conditions examined, with especially elevated risks for osteoporosis (IRR, 4.7; 95% CI, 4.1-5.5) and cardiomyopathy (IRR, 4.2 95% CI, 3.4-5.3). Compared with the Kaiser Permanente Southern California cohort, CHS survivors had an overall lower (SIR, 0.68; 95% CI, 0.65-0.72) incidence of developing any health condition, with noticeably lower incidence of hyperlipidemia (SIR, 0.7; 95% CI, 0.64-0.75).

CONCLUSION

AYA cancer survivors in Israel are at increased risk for developing chronic conditions compared with individuals without cancer, but the overall incidence was lower than in US survivors. These findings may allow for refinement of surveillance recommendations for AYA survivors, taking into consideration regional differences in sociodemographic characteristics and cancer care.

PLAIN LANGUAGE SUMMARY

The burden of chronic conditions was consistently greater in Israeli adolescent and young adult cancer survivors compared with individuals without cancer, with clear differences in risk of specific conditions by cancer diagnosis. However, the overall incidence of chronic conditions in Israeli survivors was generally lower than in US survivors.

Communication and swallowing management in childhood brain tumour or leukaemia: A survey of health professionals and consumers

Purpose: Brain tumour and leukaemia represent the most common childhood cancers and can result in communication and swallowing difficulties. The purpose of this study was to survey health professionals and consumers regarding the management of communication and swallowing difficulties in children with brain tumour or leukaemia (CBTL).Method: In this study participants completed a survey focussing on (1) communication and swallowing assessment and intervention, (2) multidisciplinary team (MDT) practices and (3) risk factors. Quantitative data were reported using descriptive statistics. Qualitative data were analysed using NVivo12 Qualitative Data Analysis Software.Result: Twenty-four participants were included (22 health professionals; two consumers). Most participants (≥80%) agreed that comprehensive and regular communication and swallowing assessments improved outcomes. Communication and swallowing interventions were reported to improve outcomes by 96% of participants. MDT care was considered essential in improving outcomes. Speech-language pathologists were the primary health professional identified in communication management; additional multidisciplinary health professionals were highlighted in swallowing management. Risk factors were identified across three categories: cancer-related, treatment-related and child-factors.Conclusion: This study collates the expertise and experience of multidisciplinary health professionals and consumers which can be used to guide assessment and intervention for communication and swallowing in CBTL. It also provides perspectives on MDT care and consideration of patient values and risk factors.

Immunosenescence in Childhood Cancer Survivors and in Elderly: A Comparison and Implication for Risk Stratification

The population of childhood cancer survivors (CCS) has grown rapidly in recent decades. Although cured of their original malignancy, these individuals are at increased risk of serious late effects, including age-associated complications. An impaired immune system has been linked to the emergence of these conditions in the elderly and CCS, likely due to senescent immune cell phenotypes accompanied by low-grade inflammation, which in the elderly is known as "inflammaging." Whether these observations in the elderly and CCS are underpinned by similar mechanisms is unclear. If so, existing knowledge on immunosenescent phenotypes and inflammaging might potentially serve to benefit CCS. We summarize recent findings on the immune changes in CCS and the elderly, and highlight the similarities and identify areas for future research. Improving our understanding of the underlying mechanisms and immunosenescent markers of accelerated immune aging might help us to identify individuals at increased risk of serious health complications.

Long-term care for people treated for cancer during childhood and adolescence

Worldwide advances in treatment and supportive care for children and adolescents with cancer have resulted in a increasing population of survivors growing into adulthood. Yet, this population is at very high risk of late occurring health problems, including significant morbidity and early mortality. Unique barriers to high-quality care for this group include knowledge gaps among both providers and survivors as well as fragmented health-care delivery during the transition from paediatric to adult care settings. Survivors of childhood and adolescent cancer are at risk for a range of late-occuring side-effects from treatment, including cardiac, endocrine, pulmonary, fertility, renal, psychological, cognitive, and socio-developmental impairments. Care coordination and transition to adult care are substantial challenges, but can be empowering for survivors and improve outcomes, and could be facilitated by clear, effective communication and support for self-management. Resources for adult clinical care teams and primary care providers include late-effects surveillance guidelines and web-based support services.

Who Knows? Information Received, and Knowledge about, Cancer, Treatment and Late Effects in a National Cohort of Long-Term Childhood, Adolescent and Young Adult Cancer Survivors

Simple Summary

With the growing population of cancer survivors, survivorship management has become central for both medical professionals and patients. This entails, among other factors, empowering survivors with the necessary knowledge about their medical history and their risk for late effects, because informed patients make better lifestyle and health choices. Although a lack of information and low satisfaction with information received are fairly well-documented phenomena among childhood cancer survivors, less is known about survivors of young adult cancer and populations of long-term survivors no longer engaged in follow-up care. This paper aims to fill this gap by investigating information provision in childhood, adolescent and young adult cancer survivors.

Abstract

Background: Knowledge of medical history and late effects is central in modern survivorship management, especially for long-term childhood, adolescent and young adult cancer survivors’ (CAYACS) with long life expectancy rates and high risks of late effects. Identifying information and knowledge gaps is, therefore, important. As part of the population-based NOR-CAYACS study, we investigated the following: (1) written information received about their disease and treatment, and any information about late effects; (2) satisfaction with this information and associated factors; (3) knowledge about late effects and factors associated with low knowledge of specific late effects. Material and methods: A questionnaire-based survey (Nor-CAYACS) was mailed to 5361 CAYACS (childhood cancers, breast and colorectal cancer, acute lymphatic leukemia, non-Hodgkin lymphoma and malignant melanoma) identified by the Cancer Registry of Norway (CRN). Of these, 2018 answered questions about disease and late effects information and knowledge. Exposure variables were extracted from the questionnaire and CRN. Unfortunately, it was not possible to stratify by treatment in the analyses. We ran descriptive statistics for comparisons and logistic regressions to identify factors associated with outcomes of interest. Results: Overall, 50% to 60% of survivors reported not having received written information about their disease and treatment, or any information about late effects. There was a large variation in reported knowledge across 17 late effects. Lower levels of knowledge were associated with male sex, lower education and poorer health literacy in multivariable regression models. Conclusions: Knowledge of cancer history and risks of late effects is essential for effective self-management, yet significant information and knowledge gaps were reported in this population-based sample of long-term CAYACS. Systematic approaches to making (up-to-date) information available to long-term survivors are needed to ensure that information does not get lost in medical and life transitions.

Leveraging Clinical Informatics Tools to Extract Cumulative Anthracycline Exposure, Measure Cardiovascular Outcomes, and Assess Guideline Adherence for Children With Cancer

PURPOSE

Cardiovascular disease is a significant cause of late morbidity and mortality in survivors of childhood cancer. Clinical informatics tools could enhance provider adherence to echocardiogram guidelines for early detection of late-onset cardiomyopathy.

METHODS

Cancer registry data were linked to electronic health record data. Structured query language facilitated the construction of anthracycline-exposed cohorts at a single institution. Primary outcomes included the data quality from automatic anthracycline extraction, sensitivity of International Classification of Disease coding for heart failure, and adherence to echocardiogram guideline recommendations.

RESULTS

The final analytic cohort included 385 pediatric oncology patients diagnosed between July 1, 2013, and December 31, 2018, among whom 194 were classified as no anthracycline exposure, 143 had low anthracycline exposure (< 250 mg/m²), and 48 had high anthracycline exposure (≥ 250 mg/m²). Manual review of anthracycline exposure was highly concordant (95%) with the automatic extraction. Among the unexposed group, 15% had an anthracycline administered at an outside institution not captured by standard query language coding. Manual review of echocardiogram parameters and clinic notes yielded a sensitivity of 75%, specificity of 98%, and positive predictive value of 68% for International Classification of Disease coding of heart failure. For patients with anthracycline exposure, 78.5% (n = 62) were adherent to guideline recommendations for echocardiogram surveillance. There were significant association with provider adherence and race and ethnicity (P = .047), and 50% of patients with Spanish as their primary language were adherent compared with 90% of patients with English as their primary language (P = .003).

CONCLUSION

Extraction of treatment exposures from the electronic health record through clinical informatics and integration with cancer registry data represents a feasible approach to assess cardiovascular disease outcomes and adherence to guideline recommendations for survivors.

Integration of cancer registry and electronic health record data to construct a childhood cancer survivorship cohort, facilitate risk stratification for late effects, and assess appropriate follow-up care

BACKGROUND

This retrospective study harnessed an institutional cancer registry to construct a childhood cancer survivorship cohort, integrate electronic health record (EHR) and geospatial data to stratify survivors based on late-effect risk, analyze follow-up care patterns, and determine factors associated with suboptimal follow-up care.

PROCEDURE

The survivorship cohort included patients ≤18 years of age reported to the institutional cancer registry between January 1, 1994 and November 30, 2012. International Classification of Diseases for Oncology, third revision (ICD-O-3) coding and treatment exposures facilitated risk stratification of survivors. The EHR was linked to the cancer registry based on medical record number (MRN) to extract clinic visits.

RESULTS

Five hundred and ninety pediatric hematology-oncology (PHO) and 275 pediatric neuro-oncology (PNO) survivors were included in the final analytic cohort. Two hundred and eight-two survivors (32.6%) were not seen in any oncology-related subspecialty clinic at Duke 5-7 years after initial diagnosis. Factors associated with follow-up included age (p = .008), diagnosis (p < .001), race/ethnicity (p = .010), late-effect risk strata (p = .001), distance to treatment center (p < .0001), and area deprivation index (ADI) (p = .011). Multivariable logistic modeling attenuated the association for high-risk (OR 1.72; 95% CI 0.805, 3.66) and intermediate-risk (OR 1.23, 95% CI 0.644, 2.36) survivors compared to survivors at low risk of late effects among the PHO cohort. PNO survivors at high risk for late effects were more likely to follow up (adjusted OR 3.66; 95% CI 1.76, 7.61).

CONCLUSIONS

Nearly a third of survivors received suboptimal follow-up care. This study provides a reproducible model to integrate cancer registry and EHR data to construct risk-stratified survivorship cohorts to assess follow-up care.

Personalized Massive Open Online Course for Childhood Cancer Survivors: Behind the Scenes

BACKGROUND

Today, in France, it is estimated that 1 in 850 people aged between 20 and 45 years has been treated for childhood cancer, which equals 40,000 to 50,000 people. As late effects of the cancer and its treatment affect a large number of childhood cancer survivors (CCS) and only 30% of them benefit from an efficient long-term follow-up care for prevention, early detection, and treatment of late effects, health education of CCS represents a challenge of public health.

OBJECTIVES

Massive open online courses (MOOCs) are a recent innovative addition to the online learning landscape. This entertaining and practical tool could easily allow a deployment at a national level and make reliable information available for all the CCS in the country, wherever they live.

METHODS

The MOOC team brings together a large range of specialists involved in the long-term follow-up care, but also associations of CCS, video producers, a communication consultant, a pedagogical designer, a cartoonist and a musician. We have designed three modules addressing transversal issues (lifestyle, importance of psychological support, risks of fertility problems) and eight modules covering organ-specific problems. Detailed data on childhood cancer treatments received were used to allocate the specific modules to each participant.

RESULTS

This paper presents the design of the MOOC entitled "Childhood Cancer, Living Well, After," and how its feasibility and its impact on CCS knowledge will be measured. The MOOC about long-term follow-up after childhood cancer, divided into 11 modules, involved 130 participants in its process, and resulted in a 170-minute film. The feasibility study included 98 CCS (31 males vs. 67 females; p < 0.0001).

CONCLUSION

Such personalized, free, and online courses with an online forum and a possible psychologist consultation based on unique characteristics and needs of each survivor population could improve adherence to long-term follow-up without alarming them unnecessarily.

Use of electronic patient data storage for evaluating and setting the risk category of late effects in childhood cancer survivors

BACKGROUND

Many of the late effects of cancer treatment in childhood may occur even decades after the treatment, and only a minority of the survivors remain as healthy as their peers. Providing appropriate long-term care for childhood cancer survivors after transition to primary health care is a challenge. Both survivors and primary care providers need information on potential late effects. The lack of a systematic late effect follow-up plan may lead to excessive use of health care services or delayed intervention. While manual compilation of individual follow-up plans is time consuming for experienced clinicians, electronic algorithms may be feasible.

PROCEDURE

In Finland, international guidelines for determining the risk of late effects have been implemented. Nationally, Turku University Hospital was asked with developing an automatized system for calculating the risk of late effects, based on electronic patient records saved in the hospital data lake. An electronic algorithm that uses details from exposure-based health screening guidelines published by the Children's Oncology Group was created. The results were compared with those manually extracted by an experienced clinician.

RESULTS

Significant concordance between the manual and algorithm-based risk classification was found. A total of 355 patients received a classification using the algorithm, and 325 of those matched with the manual categorization, producing a Cohen's coefficient of 0.91 (95% confidence interval 0.88-0.95).

CONCLUSION

Automated algorithms can be used to categorize childhood cancer survivors efficiently and reliably into late effect risk groups. This further enables automatized compilation of appropriate individual late effect follow-up plan for all survivors.

Self-reported late effects and long-term follow-up care among 1889 long-term Norwegian Childhood, Adolescent, and Young Adult Cancer Survivors (the NOR-CAYACS study)

Purpose

The majority of childhood, adolescent, and young adult cancer survivors (CAYACS) are at risk of late effects but may not receive long-term follow-up care for these. Here, we investigated (1) self-reported late effects, (2) long-term follow-up care, and (3) factors associated with receiving follow-up care in a population-based sample of Norwegian long-term CAYACS.

Methods

Survivors were identified by the Cancer Registry of Norway. All > 5-year survivors diagnosed between 1985 and 2009 with childhood cancer (CCS, 0–18 years old, excluding CNS), breast cancer (BC, stages I–III), colorectal cancer (CRC), leukemias (LEUK), non-Hodgkin lymphoma (NHL), or malignant melanoma (MM) at age 19–39 years were mailed a questionnaire (NOR-CAYACS study). Descriptive statistics and logistic regression models were used to analyze occurrence of late effects, long-term follow-up care for these, and associated factors.

Results

Of 2104 responding survivors, 1889 were eligible for analyses. Of these, 68% were females, with a mean age of 43 years at survey, on average 17 years since diagnosis, and diagnosed with CCS (31%), BC (26%), CRC (8%), NHL (12%), LEUK (7%), and MM (16%). Overall, 61.5% reported the experience of at least one late effect, the most common being concentration/memory problems (28.1%) and fatigue (25.2%). Sixty-nine percent reported not having received long-term follow-up care focusing on late effects. Lower age at survey (p = 0.001), higher education (p = 0.012), and increasing number of late effects (p = < 0.001) were associated with increased likelihood of follow-up care in the multivariate model.

Conclusions

The majority of survivors reported at least one late effect, but not receiving specific follow-up care for these. This indicates a need for structured models of long-term follow-up to ensure adequate access to care.

Transition of Care for Children with High-Grade Central Nervous System Tumors

The increase in survival rates of children with high-grade central nervous system tumors has highlighted the necessity for and challenges associated with transition of care as these children grow into adult life. Late recurrence and treatment effects are some of the conditions that require care after transition. Several models of transition have been proposed in the literature. An effective transition will not only ensure adequate continuity of care but will also include assessment of effectiveness of the transition by health care personnel and the patient/patient's family themselves.

Risk stratification of young adult survivors of cancer to estimate hospital morbidity burden: applicability of a pediatric therapy-based approach

Purpose

Children and young adults (CYA) are at risk of late morbidity following cancer treatment, with risk varying by disease type and treatment received. Risk-stratified levels of aftercare which stratify morbidity burden to inform the intensity of long-term follow-up care, are well established for survivors of cancer under the age of 18 years, utilizing the National Cancer Survivor Initiative (NCSI) approach. We investigated the applicability of risk-stratified levels of aftercare in predicting long-term morbidity in young adults (YA), aged 18–29 years.

Methods

Long-term CYA survivors followed-up at a regional center in the North of England were risk-stratified by disease and treatments received into one of three levels. These data were linked with local cancer registry and administrative health data (Hospital Episode Statistics), where hospital activity was used as a marker of late morbidity burden.

Results

Poisson modelling with incident rate ratios (IRR) demonstrated similar trends in hospital activity for childhood (CH) and YA cancer survivors across NCSI risk levels. NCSI levels independently predicted long-term hospitalization risk in both CH and YA survivors. Risk of hospitalization was significantly reduced for levels 1 (CH IRR 0.32 (95% CI 0.26–0.41), YA IRR 0.06 (95% CI 0.01–0.43)) and 2; CH IRR 0.46 (95% CI 0.42-0.50), YA IRR 0.49 (95% CI 0.37-0.50)), compared with level 3.

Conclusions

The NCSI pediatric late-effects risk stratification system can be effectively and safely applied to cancer patients aged 18–29, independent of ethnicity or socioeconomic position.

Implications for Cancer Survivors

To enhance quality of care and resource utilization, long-term aftercare of survivors of YA cancer can and should be risk stratified through adoption of approaches such as the NCSI risk-stratification model.

Current and coming challenges in the management of the survivorship population

With the widespread adoption of multimodality treatment, 5-year survival of children diagnosed with cancer has improved dramatically in the past several decades from approximately 60% in 1970 to greater than 85% currently. As a result, there are an estimated nearly half a million long-term survivors of childhood cancer living in the United States today. However, survivors have, on average, significantly greater serious medical and psychosocial late effects compared with the general population. In this review, we will discuss the current epidemiology of childhood cancer survivorship, including new methods to estimate the burden of late effects and genetic susceptibility toward late effects. We will also review the development of surveillance guidelines for childhood cancer survivors and early toxicity signals from novel agents now being tested and used increasingly to treat pediatric and adult cancers. We conclude with an overview of current models of survivorship care and areas for future research.

Standardizing the categorizations of models of aftercare for survivors of childhood cancer

BACKGROUND

With significant improvements in the survival rates for most childhood cancers, there is increased pressure to determine how follow-up or aftercare for survivors is best structured.

MAIN BODY

Previous work in this area has not been consistent in how it categorizes models of aftercare, which risks confusion between studies and evaluations of different models. The adoption of a standardized method for classifying and describing different models of aftercare is necessary in order to maximize the applicability of the available evidence. We identify some of the different ways models of aftercare have been classified in previous research. We then propose a revised taxonomy which allows for a more consistent classification and description of these models. The proposed model bases the classification of models of aftercare on who is the lead provider, and then collects data on five other key features: which other providers are involved in providing aftercare, where care is provided, how are survivors engaged, which services are provided, and who receives aftercare.

CONCLUSION

There is a good deal of interest in the effectiveness of different models of aftercare. Future research in this area would be assisted by the adoption of a shared taxonomy that will allow programs to be identified by their structural type.

The crucial role of primary care providers in the long-term follow-up of adult survivors of childhood cancer

Purpose: The potential physical or psychosocial factors that play a role in the progression of childhood cancer survivors into adulthood are essential in the identification of an effective patient-centred approach to therapy. Despite the presence of guidelines published by the Children’s Oncology Group, knowledge of the long-term health sequelae for the care of survivors is sub-optimal. Here, the pertinent clinical issues that may affect survivors of childhood cancer are outlined for primary care providers (PCPs).

Methods: This literature search identified articles using PubMed, EMBASE Ovid, and the Cochrane Library to determine high-quality, multicenter randomized controlled trials, systematic reviews, meta-analyses, and practice guidelines from December 1998 to December 2018. The keywords of the search were primary care providers; childhood cancer survivors; long-term care and mental health. Guidelines and research using retrospective studies are used to compile evidence to address PCP’s involvement and to describe the factors involved in the adult onset of psychological disorders in survivors of childhood cancer. A focus of this article is to use the literature that evaluated pediatric cancer survivors for at least five years post diagnosis and had received cancer treatment including chemotherapy, radiation, bone marrow transplant, or surgery. Additional research focused on primary care physicians addressing the care of childhood cancer survivors. Here, we aim to provide PCPs and physicians with a critical yet concise update on the recent advancements for this important healthcare topic. This paper presents an overview of previously published reviews and, as such, requires no ethics approval.

Results: Childhood cancer survivors can develop symptoms of depression and suffer from low self-esteem from their diagnosis and treatment regimens. These symptoms can result in functional impairment. Child diagnosis also affects parental health, resulting in the experience of psychological, emotional and traumatic stress. The feeling of helplessness and guilt on parents leads to the potentiation of depression on the child survivor.

Conclusions: Primary care providers, in collaboration with clinician specialists, must be vigilant in providing consistent long-term care. This approach will ensure clear constant communication to help address the challenges faced by the families and survivors as they progress through adulthood.

Implications for cancer survivors: Encouraging primary care providers to become knowledgeable and comfortable in utilizing appropriate resources is achieved through consultation with oncology or psychiatric specialists or with online resources for safer management of childhood cancer survivors. The implications for this patient population would ultimately allow for a more patient-centred approach to therapy.

Dysautonomia in Childhood Cancer Survivors: A Widely Underestimated Risk

PURPOSE

Survival rate of childhood cancers is now reaching 80% overall. However, early or late complications related to surgery, chemotherapy, and radiotherapy remain at a high rate and greatly increase the risk of late mortality. The objective of this study is to assess the autonomic nervous system (ANS) activity, measured through heart rate variability indices in childhood cancer survivors compared with healthy controls.

METHODS

This prospective study included 51 long-term childhood cancer survivors diagnosed before 15 years of age between 1987 and 1992 and controlled for age and sex with healthy volunteers.

RESULTS

We observed a significant increase in spontaneous heart rate (beats per minute) (67 ± 10 vs. 60 ± 10, p = 0.001), and all the studied parameters showed a significantly altered ANS activity in cases compared with healthy controls. In both groups, the main cofactors of dysautonomia (tobacco, drugs, cannabis, estro-progestative pills, alcohol, limited physical activity) were analyzed without any significant difference. The effect of cancer treatments received was not analyzed due to the small number of participants.

CONCLUSION

The results showed a significant ANS dysfunction in childhood cancer survivors compared with healthy controls and suggested the value of autonomic screening to underscore and possibly quantify the effect of the cancer treatments in a larger cohort. This evaluation could lead to the recommendation to increase physical activity, the most efficient way known to improve ANS activity, as already shown in other pathologies (breast cancer).

Surveillance for Late Effects in Childhood Cancer Survivors

Many childhood cancer survivors carry a significant risk for late morbidity and mortality, a consequence of the numerous therapeutic exposures that contribute to their cure. Focused surveillance for late therapy-related complications provides opportunities for early detection and implementation of health-preserving interventions. The substantial body of research that links therapeutic exposures used during treatment of childhood cancer to adverse outcomes among survivors enables the characterization of groups at the highest risk for developing complications related to specific therapies; however, methods available to optimize screening strategies to detect these therapy-related complications are limited. Moreover, the feasibility of conducting clinical trials to test screening recommendations for childhood cancer survivors is limited by requirements for large sample sizes, lengthy study periods, prohibitive costs, and ethical concerns. In addition, the harms of screening should be considered, including overdiagnosis and psychological distress. Experts in several countries have developed guideline recommendations for late effects surveillance and have collaborated to harmonize these recommendations internationally to enhance long-term follow-up care and quality of life for childhood cancer survivors. Methods used in these international efforts include systematic literature searches, development of evidence-based summaries, rigorous evaluation of the evidence, and formulation of consensus-based surveillance recommendations for each late complication. Alternate methods to refine recommendations, such as cumulative burden assessment and risk prediction and cost-effectiveness modeling, may provide novel approaches to guide survivorship care in this vulnerable population and, thus, represents a worthy objective for future international survivorship collaborations.

'Re-engage' pilot study protocol: a nurse-led eHealth intervention to re-engage, educate and empower childhood cancer survivors

INTRODUCTION

Many childhood cancer survivors are disengaged from cancer-related follow-up care despite being at high risk of treatment-related late effects. Innovative models of long-term follow-up (LTFU) care to manage ongoing treatment-related complications are needed. 'Re-engage' is a nurse-led eHealth intervention designed to improve survivors' health-related self-efficacy, targeted at survivors disengaged from follow-up. Re-engage aims to overcome survivor- and parent-reported barriers to care and ensure survivors receive the care most appropriate to their risk level.

METHODS AND ANALYSIS

This study will recruit 30 Australian childhood cancer survivors who are not receiving any cancer-related care. Participation involves two online/telephone consultations with a survivorship nurse for medical assessment, a case review, risk stratification and creation of a care plan by a multidisciplinary team of specialists. We will assess the feasibility of implementing 'Re-engage' and its acceptability to participants and health professionals involved. The primary outcome will be survivors' health-related self-efficacy, measured at baseline and 1 and 6 months postintervention. Secondary outcomes will include the effect of 'Re-engage' on survivors' health behaviours and beliefs, engagement in healthcare, information needs and emotional well-being. We will also document the cost per patient to deliver 'Re-engage'. If Re-engage is acceptable, feasible and demonstrates early efficacy, it may have the potential to empower survivors in coordinating their complex care, improving survivors' long-term engagement and satisfaction with care. Ideally, it will be implemented into clinical practice to recall survivors lost to follow-up and reduce the ongoing burden of treatment for childhood cancer.

ETHICS AND DISSEMINATION

The study protocol has been approved by the South Eastern Sydney Local Health District Human Research Ethics Committee (reference number: 16/366). The results will be disseminated in peer-reviewed journals and at scientific conferences. A lay summary will be published on the Behavioural Sciences Unit website.

Cancer Survivorship Care: Person Centered Care in a Multidisciplinary Shared Care Model

Survivors of childhood and adult-onset cancer are at lifelong risk for the development of late effects of treatment that can lead to serious morbidity and premature mortality. Regular long-term follow-up aiming for prevention, early detection and intervention of late effects can preserve or improve health. The heterogeneous and often serious character of late effects emphasizes the need for specialized cancer survivorship care clinics. Multidisciplinary cancer survivorship care requires a coordinated and well integrated health care environment for risk based screening and intervention. In addition survivors engagement and adherence to the recommendations are also important elements. We developed an innovative model for integrated care for cancer survivors, the "Personalized Cancer Survivorship Care Model", that is being used in our clinic. This model comprises 1. Personalized follow-up care according to the principles of Person Centered Care, aiming to empower survivors and to support self management, and 2. Organization according to a multidisciplinary and risk based approach. The concept of person centered care is based on three components: initiating, integrating and safeguarding the partnership with the patient. This model has been developed as a universal model of care that will work for all cancer survivors in different health care systems. It could be used for studies to improve self efficacy and the cost-effectiveness of cancer survivorship care.

Long-term follow-up after childhood cancer in France supported by the SFCE-force and weakness-current state, results of a questionnaire and perspectives

OBJECTIVE

The survival rate of children treated for cancer is currently about 80% at 5 years and we estimate that about 50,000 adults in France have survived childhood cancer. In 2011, there was a call for projects relating to long-term follow-up (LTFU), which led to several studies being conducted. Five years later, we sent a questionnaire to present LTFU in France and describe its strengths and weaknesses and to establish appropriate steps that should be taken.

METHODS

A questionnaire was sent by email to all the members of the French Society of Childhood Cancers in spring 2016. The study involved 44 centres/hospitals with a Paediatric Oncology Department.

RESULTS

54 answers were analysed, provided by 31/44 (70%) centres working together with the French Society of Childhood Cancers. Screening is the main objective of LTFU care (90%). The main difficulties that arose were: lack of sufficient time to devote to this activity (57%), difficulties contacting adult childhood cancer survivors (aCCSs) (26%), aCCSs who ultimately did not show up to the consultation (19%), cost (15%), and lack of organization (13%). Seven LTFU programmes were identified: two regional organizations (Rhône Alpes and Grand Ouest), four centre-size organizations, and one national study (involving 15 Haematology Centres) relating to Child and Adolescent Leukaemia.

CONCLUSION

LTFU is a major concern for French centres specialized in paediatric oncology. Organization is not well defined and difficulties still arise (Who are the best care providers? What frequency of care is most appropriate? etc.). Advances in knowledge: LTFU focused on health problems (physical, psychological, social, economic issues) that affect CCSs is needed to ensure that these patients regain the most optimal physical and emotional health possible. Practitioners suggest different ways to improve LTFU, such as national co-operation with Epidemiology Registers to promote homogenous LTFU care.

Risk stratification of childhood cancer survivors necessary for evidence-based clinical long-term follow-up

BACKGROUND

Reorganisation of clinical follow-up care in England was proposed by the National Cancer Survivorship Initiative (NCSI), based on cancer type and treatment, ranging from Level 1 (supported self-management) to Level 3 (consultant-led care). The objective of this study was to provide an investigation of the risks of serious adverse health-outcomes associated with NCSI Levels of clinical care using a large population-based cohort of childhood cancer survivors.

METHODS

The British Childhood Cancer Survivor Study (BCCSS) was used to investigate risks of specific causes of death, subsequent primary neoplasms (SPNs) and non-fatal non-neoplastic outcomes by NCSI Level.

RESULTS

Cumulative (excess) risks of specified adverse outcomes by 45 years from diagnosis among non-leukaemic survivors assigned to NCSI Levels 1, 2 and 3 were for: SPNs-5% (two-fold expected), 14% (four-fold expected) and 21% (eight-fold expected); non-neoplastic death-2% (two-fold expected), 4% (three-fold expected) and 8% (seven-fold expected); non-fatal non-neoplastic condition-14%, 27% and 40%, respectively. Consequently overall cumulative risks of any adverse health outcome were 21%, 45% and 69%, respectively.

CONCLUSIONS

Despite its simplicity the risk stratification tool provides clear and strong discrimination between survivors assigned to different NCSI Levels in terms of long-term cumulative and excess risks of serious adverse outcomes.

Models of childhood cancer survivorship care in Australia and New Zealand: Strengths and challenges

AIM

Childhood cancer survivors remain at risk of developing life-altering and/or life-threatening health conditions following the completion of curative treatment. However, no uniform model of care for childhood cancer survivors exists in Australia and New Zealand (ANZ). This study reports on current childhood cancer survivorship care in ANZ, highlighting the challenges childhood cancer survivor long-term follow-up (LTFU) clinics face.

METHODS

We conducted semistructured, telephone interviews with the pediatric medical director and clinical nurse consultant from all 11 LTFU clinics at tertiary referral pediatric oncology units across ANZ (n = 19; 100% response rate). Data were analyzed using NVivo10.

RESULTS

Participants unanimously identified limited options for transitioning older survivors out of pediatrics and inadequate funding as central challenges to the provision of best-practice LTFU care. There is duplication of resource development between clinics (e.g. survivorship care plan templates and clinic systems). Although participants recognized an overly prescriptive model of LTFU care as potentially unfeasible, the majority endorsed a national, or even bi-national, model of care that could be tailored to meet the needs of their local environment.

CONCLUSION

The lack of an accepted model of optimal childhood cancer survivorship care across ANZ prevents the synergistic development of survivorship guidelines, survivorship care plans, transition pathways, information technology solutions, funding streams and late effects data consortiums. Sufficient resources to facilitate growth may be difficult to secure if approached by individual centers rather than via a national, cooperative effort. Improved solutions are urgently needed for transitioning survivors to appropriate care beyond the pediatric age.

Clinic Attendance of Youth With Sickle Cell Disease on Hydroxyurea Treatment

OBJECTIVE

The objective of this study is to describe rates of clinic attendance of youth with sickle cell disease prescribed hydroxyurea and examine potential demographic and medical factors related to consistent clinic attendance.

METHODS

Participants included 148 youth diagnosed with sickle cell disease and prescribed hydroxyurea during a single calendar year. Clinic attendance and potential demographic and medical factors related to attendance were extracted via systematic retrospective medical chart review.

RESULTS

Youth attended 90.3% of scheduled appointments and 85.1% of youth attended at least 80% of scheduled clinic appointments during the study window. Adjusting for other factors, multivariate analysis revealed families with fewer children in the household, families with private insurance, youth experiencing fever, and youth not experiencing pain during the calendar year were more likely to consistently attend clinic visits.

CONCLUSIONS

Adherence to clinic appointments is critical to optimizing health outcomes for youth with sickle cell disease and integral for adequate monitoring of youth prescribed hydroxyurea, in particular. Findings may aid providers in appropriately identifying possible barriers to clinic attendance to develop attendance promotion interventions.

Long-Term Follow-up Consultation After Childhood Cancer in the Rhône-Alpes Region of France: Feedback From Adult Survivors and Their General Practitioners

PURPOSE

We evaluated the satisfaction of adult survivors of childhood cancers and their general practitioners (GP) after a long-term consultation.

METHODS

The first Long-term Follow-up Study in Oncology (SALTO1) is a prospective cohort study of survivors of childhood cancers (except leukemia) diagnosed between 1987 and 1992 in the Rhône-Alpes and Auvergne regions of France. Of the 481 patients eligible for the study, 150 participated in a long-term consultation with a pediatric oncologist and an internist, after which survivors and their GPs received long-term plans and recommendations based on consultation findings. A year after the consultation, survivors and their GPs assessed their satisfaction with the process.

RESULTS

Of the 150 survivor participants in the long-term follow-up, 120 (80%) completed the satisfaction form, with 107 (89%) reporting satisfaction. Forty-eight (32%) expressed strengthening their follow-up as a consequence of the consultation. Of the 79 survivors sent recommendations, 76 (96%) reported reading them, most (n = 68; 86%) found them useful, and 56 (71%) followed recommendations. Of the 107 GPs of the survivors, 82 (77%) conceded having been poorly informed about long-term complications for their patients after chemotherapy, and 93 (88%) appreciated having a hospital contact available for these patients.

CONCLUSION

The long-term consultations ultimately enhanced medical follow-up of survivor participants, improving knowledge of both patients and family physicians regarding the patients' early disease, its treatments, and possible concerns, and offering consultative resources of medical specialists. The levels of participation of survivors and their physicians and reported satisfaction encourage the adoption of such consultations throughout France.

Advancing a comprehensive cancer care agenda for children and their families: Institute of Medicine Workshop highlights and next steps

This article highlights key findings from the "Comprehensive Cancer Care for Children and Their Families" March 2015 joint workshop by the Institute of Medicine (IOM) and the American Cancer Society. This initiative convened more than 100 family members, clinician investigators, advocates, and members of the public to discuss emerging evidence and care models and to determine the next steps for optimizing quality-of-life outcomes and well-being for children and families during pediatric cancer treatment, after treatment completion, and across the life spectrum. Participants affirmed the triple aim of pediatric oncology that strives for every child with cancer to be cured; provides high-quality palliative and psychosocial supportive, restorative, and rehabilitative care to children and families throughout the illness course and survivorship; and assures receipt of high-quality end-of-life care for patients with advancing disease. Workshop outcomes emphasized the need for new pediatric cancer drug development and identified critical opportunities to prioritize palliative care and psychosocial support as an integral part of pediatric cancer research and treatment, including the necessity for adequately resourcing these supportive services to minimize suffering and distress, effectively address quality-of-life needs for children and families at all stages of illness, and mitigate the long-term health risks associated with childhood cancer and its treatment. Next steps include dismantling existing silos and enhancing collaboration between clinical investigators, disease-directed specialists, and supportive care services; expanding the use of patient-reported and parent-reported outcomes; effectively integrating palliative and psychosocial care; and clinical communication skills development.

Preferences for long-term follow-up care in childhood cancer survivors

Follow-up care is important for childhood cancer survivors to facilitate early detection and treatment of late effects. We aimed to describe preferences for different organisational aspects and models of follow-up care among Swiss childhood cancer survivors, and characteristics associated with preferences for different models. We contacted 720 survivors aged 18+ years, diagnosed with cancer after 1990 (age 0-16 years), registered in the Swiss Childhood Cancer Registry (SCCR), and Swiss resident, who previously participated in a baseline survey. They received questionnaires to assess attendance and preferences for follow-up (rated on 4-point scales, 0-3). Clinical information was available from the SCCR. Survivors (n = 314: response rate 43.6%; 47.8% still attended follow-up) rated clinical reasons for follow-up higher than supportive reasons (p < .001). They rated checking for cancer recurrence (mean = 2.78, SD = 0.53) and knowing about risks for my children most important (mean = 2.22, SD = 0.83). They preferred to attend a children's hospital (mean = 1.94, SD = 1.11), adult hospital (mean = 1.86, SD = 0.98) or general practitioner (mean = 1.86, SD = 1.01) rather than a central specialised late effects clinic (mean = 1.25, SD = 1.06, p < .001), and be seen by paediatric (mean = 2.24, SD = 0.72) or medical oncologist (mean = 2.17, SD = 0.69). Survivors preferred decentralised clinic-based follow-up, rather than one central specialised late effects clinic. Survivors' preferences should be considered to ensure future attendance.

The experience of survival following allogeneic haematopoietic stem cell transplantation in New South Wales, Australia

Allogeneic haematopoietic stem cell transplantation (allo-HSCT) entails long-term morbidities that impair survivors' quality of life through broad physical and psychosocial sequelae. Current data and survival measurements may be inadequate for contemporary Australian allo-HSCT recipients. This study sought to comprehensively describe survivorship in an up-to-date, local setting through validated measurements and a novel questionnaire designed to complement and address limitations of current instruments. All adults who received an allo-HSCT between 2000 and 2012 in New South Wales were eligible and included, if alive, those literate and consenting to the study, which encompassed seven survey instruments. Four hundred and forty-three survivors participated, which is 76% of contactable (n=583) and 66% of eligible survivors (n= 669). Chronic GVHD (cGVHD) and co-morbidity rates were similar to published data. Noteworthy results include prevalent sexual dysfunction (66% females, 52% males), loss of income (low income increased from 21 to 36%, P<0.001) and employment (full-time employment fell from 64 to 33%, P<0.001), suboptimal vaccination (31% complete), and health screening (≈50%). Risk factors for poor vaccination and health screening were cGVHD, younger age, less education, rural/regional residence and transplantation <2 years. This study suggests that improvement in survivorship may necessitate structural changes in the current delivery of health services.

Preferences for the organization of long-term follow-up in adolescent and young adult cancer survivors

PURPOSE

As survival rates of adolescent and young adult (AYA) cancer patients increase, a growing number of AYA cancer survivors need follow-up care. However, there is little research on their preferences for follow-up care. We aimed to (1) describe AYA cancer survivors' preferences for the organization and content of follow-up care, (2) describe their preferences for different models of follow-up, and (3) investigate clinical and sociodemographic characteristics associated with preferences for the different models.

METHODS

AYA cancer survivors (diagnosed with cancer at age 16-25 years; ≥5 years after diagnosis) were identified through the Cancer Registry Zurich and Zug. Survivors completed a questionnaire on follow-up attendance, preferences for organizational aspects of follow-up care (what is important during follow-up, what should be included during appointments, what specialists should be involved, location), models of follow-up (telephone/questionnaire, general practitioner (GP), pediatric oncologist, medical oncologist, multidisciplinary team), and sociodemographic characteristics. Information on tumor and treatment was available through the Cancer Registry Zurich and Zug.

RESULTS

Of 389 contacted survivors, 160 (41.1 %) participated and 92 (57.5 %) reported still attending follow-up. Medical aspects of follow-up care were more important than general aspects (p < 0.001). Among different organizational models, follow-up by a medical oncologist was rated higher than all other models (p = 0.002). Non-attenders of follow-up rated GP-led follow-up significantly higher than attenders (p = 0.001).

CONCLUSION

Swiss AYA cancer survivors valued medical content of follow-up and showed a preference for medical oncologist-led follow-up. Implementation of different models of follow-up care might improve accessibility and attendance among AYA cancer survivors.

Predictors of attendance at specialized survivor clinics in a population-based cohort of adult survivors of childhood cancer

PURPOSE

The purpose of the present study is to determine predictors of attendance at a network of publicly funded specialized survivor clinics by a population-based cohort of adult survivors of childhood cancer.

METHODS

We conducted a retrospective study linking data on eligible patients identified in a provincial pediatric cancer registry with health administrative databases to determine attendance at five specialized survivor clinics in the Canadian province of Ontario between 1999 and 2012. Eligible survivors were treated for cancer at ≤18 years between 1986 and 2005, had survived ≥5 years from their most recent pediatric cancer event, and contributed ≥1 year of follow-up after age 18 years. We assessed the impact of cancer type, treatment intensity, cumulative chemotherapy doses, radiation, socioeconomic status, distance to nearest clinic, and care from a primary care physician (PCP) on attendance using recurrent event multivariable regression.

RESULTS

Of 7482 children and adolescents treated for cancer over the study period, 3972 were eligible for study inclusion, of which 3912 successfully linked to administrative health data. After a median of 7.8 years (range 0.2-14.0) of follow-up, 1695/3912 (43.3 %) had attended at least one adult survivor clinic visit. Significantly increased rates of attendance were associated with female gender, higher treatment intensity, radiation, higher alkylating agent exposure, higher socioeconomic status, and an annual exam by a PCP. Distance significantly impacted attendance with survivors living >50 km away less likely to attend than those living within 10 km (relative rate 0.77, p = 0.003).

CONCLUSION

Despite free access to survivor clinics, the majority of adult survivors of childhood cancer do not attend.

IMPLICATIONS FOR CANCER SURVIVORS

Alternate models of care need to be developed and assessed, particularly for survivors living far from a specialized clinic and those at lower risk of developing late effects.

Follow-up care of adolescent survivors of childhood cancer: The role of health beliefs

BACKGROUND

Little is known about follow-up care attendance of adolescent survivors of childhood cancer, and which factors foster or hinder attendance. Attending follow-up care is especially important for adolescent survivors to allow for a successful transition into adult care. We aimed to (i) describe the proportion of adolescent survivors attending follow-up care; (ii) describe adolescents' health beliefs; and (iii) identify the association of health beliefs, demographic, and medical factors with follow-up care attendance.

PROCEDURE

Of 696 contacted adolescent survivors diagnosed with cancer at ≤ 16 years of age, ≥ 5 years after diagnosis, and aged 16-21 years at study, 465 (66.8%) completed the Swiss Childhood Cancer Survivor Study questionnaire. We assessed follow-up care attendance and health beliefs, and extracted demographic and medical information from the Swiss Childhood Cancer Registry. Cross-sectional data were analyzed using descriptive statistics and logistic regression models.

RESULTS

Overall, 56% of survivors reported attending follow-up care. Most survivors (80%) rated their susceptibility for late effects as low and believed that follow-up care may detect and prevent late effects (92%). Few (13%) believed that follow-up care is not necessary. Two health beliefs were associated with follow-up care attendance (perceived benefits: odds ratio [OR]: 1.56; 95% confidence interval [CI]: 1.07-2.27; perceived barriers: OR: 0.70; 95%CI: 0.50-1.00).

CONCLUSIONS

We show that health beliefs are associated with actual follow-up care attendance of adolescent survivors of childhood cancer. A successful model of health promotion in adolescent survivors should, therefore, highlight the benefits and address the barriers to keep adolescent survivors in follow-up care.

Aspects of mental health dysfunction among survivors of childhood cancer

BACKGROUND

Some previous studies have reported that survivors of childhood cancer are at an increased risk of developing long-term mental health morbidity, whilst others have reported that this is not the case. Therefore, we analysed 5-year survivors of childhood cancer using the British Childhood Cancer Survivor Study (BCCSS) to determine the risks of aspects of long-term mental health dysfunction.

PROCEDURE

Within the BCCSS, 10 488 survivors completed a questionnaire that ascertained mental health-related information via 10 questions from the Short Form-36 survey. Internal analyses were conducted using multivariable logistic regression to determine risk factors for mental health dysfunction. External analyses were undertaken using direct standardisation to compare mental health dysfunction in survivors with UK norms.

RESULTS

This study has shown that overall, childhood cancer survivors had a significantly higher prevalence of mental health dysfunction for 6/10 questions analysed compared to UK norms. Central nervous system (CNS) and bone sarcoma survivors reported the greatest dysfunction, compared to expected, with significant excess dysfunction in 10 and 6 questions, respectively; the excess ranged from 4.4-22.3% in CNS survivors and 6.9-15.9% in bone sarcoma survivors. Compared to expected, excess mental health dysfunction increased with attained age; this increase was greatest for reporting 'limitations in social activities due to health', where the excess rose from 4.5% to 12.8% in those aged 16-24 and 45+, respectively. Within the internal analyses, higher levels of educational attainment and socio-economic classification were protective against mental health dysfunction.

CONCLUSIONS

Based upon the findings of this large population-based study, childhood cancer survivors report significantly higher levels of mental health dysfunction than those in the general population, where deficits were observed particularly among CNS and bone sarcoma survivors. Limitations were also observed to increase with age, and thus it is important to emphasise the need for mental health evaluation and services across the entire lifespan. There is evidence that low educational attainment and being unemployed or having never worked adversely impacts long-term mental health. These findings provide an evidence base for risk stratification and planning interventions.

Wellness Beyond Cancer Program: building an effective survivorship program

BACKGROUND

The Wellness Beyond Cancer Program (wbcp) was launched in 2012, first accepting patients with colorectal cancer (crc) and, subsequently, those with breast cancer (bca), with the aim of standardizing and streamlining the discharge process from our cancer centre. Patients are discharged either to the wbcp nurse practitioner or to their primary care provider (pcp). The program incorporates survivorship care plans (scps) and education classes; it also has a rapid re-entry system in case of recurrence. The objective of this paper is to describe the process by which a cancer survivorship program was developed at our institution and to present preliminary evaluation results.

METHODS

Qualitative surveys were mailed to patients and pcps 1 year after patients had been referred to the wbcp. The surveys addressed knowledge of the program content, satisfaction on the part of patients and providers, and whether scp recommendations were followed. Questions were scored on the level of agreement with each of a list of statements (1 = strongly disagree to 5 = strongly agree).

RESULTS

From March 2012 to November 2014, 2630 patients were referred to the wbcp (809 with crc, 1821 with bca). Surveys were received from 289 patients and 412 pcps. Patients and pcps gave similar scores (average: 4) to statements about satisfaction; pcps gave scores below 4 to statements about communication with the wbcp.

CONCLUSIONS

At 1 year after discharge, patients and pcps were satisfied with program content, but there is an opportunity to improve on communication and provision of cancer-specific information to the pcps. Using the wbcp to ensure a safe transition to the most appropriate health care provider, we have standardized the discharge process for crc and bca patients.

Specialty care for adult survivors of childhood cancer

As adult survivors of childhood cancer age, they are at risk for serious morbidity related to their cancer therapy. How best to manage this high‐risk population, which is often unaware of the risks and is followed by primary care clinicians unfamiliar with cancer therapy, remains understudied. In an intriguing study, Sutradhar et al report that attendance at a specialized survivor clinic results in fewer emergency department visits.

Outcomes of ovarian stimulation after treatment with chemotherapy

PURPOSE

Chemotherapeutic agents have a known gonadotoxic effect; however, it is difficult to predict the impact they may have on ovarian stimulation. The objective of this study was to evaluate response to ovarian stimulation in patients exposed to chemotherapy compared with patients who were chemotherapy-naïve.

METHODS

A retrospective cohort study of 130 patients with cancer or autoimmune disease was performed. Demographics, ovarian reserve, ovarian response and stimulation parameters, and oocyte data were compared between patients who were pre- and post-chemotherapy. Logistic regression modeling was performed to identify risk factors for cancellation and low oocyte yield, adjusting for confounders as appropriate.

RESULTS

Antral follicle count (AFC) was significantly lower in post-chemo patients (9 vs. 17, p < 0.001). Post-chemotherapy patients were more likely to be cancelled during stimulation (23 vs. 4 %, p = 0.003). Among those that went to retrieval, there was no difference in total number of oocytes (10 vs. 10, p = 0.31) or mature oocytes retrieved (8 vs. 8, p = 0.38), despite higher starting (300 vs. 450 IU, p < 0.001) and total gonadotropin (3075 vs. 4612.5 IU, p = 0.008) doses in post-chemotherapy patients. Low AFC (≤6) was associated with cycle cancellation (OR 7.7, 95 % CI 1.8-33.2) and low oocyte yield (<6) (OR 5.4, 95 % CI 1.6-17.7).

CONCLUSIONS

Patients post-chemotherapy have lower AFC compared with the chemotherapy-naïve and have higher cancellation rates. Among those who underwent oocyte retrieval, oocyte yield was similar in both groups. Low AFC was most strongly associated with cycle cancellation and oocyte yield. Post-chemotherapy patients had higher rates of cycle cancellation but did equally well as pre-chemotherapy patients if they reached retrieval.

Screening and management of adverse endocrine outcomes in adult survivors of childhood and adolescent cancer

5 year survival for childhood and adolescent cancer in developed countries is now in excess of 80% and the number of survivors of cancer continues to increase worldwide. After completion of therapy, many of these survivors will face a lifelong risk of endocrine late effects. We summarise the available evidence related to the prevalence and risk factors for endocrine late effects among adult survivors of childhood and adolescent cancer. Present screening, surveillance, and treatment recommendations differ by country and region, so we also highlight the continued effort to harmonise the international guidelines for this population.

Effect of cancer treatment on hypothalamic-pituitary function

The past 30 years have seen a great improvement in survival of children and young adults treated for cancer. Cancer treatment can put patients at risk of health problems that can develop many years later, most commonly affecting the endocrine system. Patients treated with cranial radiotherapy often develop dysfunction of the hypothalamic-pituitary axis. A characteristic pattern of hormone deficiencies develops over several years. Growth hormone is disrupted most often, followed by gonadal, adrenal, and thyroid hormones, leading to abnormal growth and puberty in children, and affecting general wellbeing and fertility in adults. The severity and rate of development of hypopituitarism is determined by the dose of radiotherapy delivered to the hypothalamic-pituitary axis. Individual growth hormone deficiencies can develop after a dose as low as 10 Gy, whereas multiple hormone deficiencies are common after 60 Gy. New techniques in radiotherapy aim to reduce the effect on the hypothalamic-pituitary axis by minimising the dose received. Patients taking cytotoxic drugs do not often develop overt hypopituitarism, although the effect of radiotherapy might be enhanced. The exception is adrenal insufficiency caused by glucocorticosteroids which, although transient, can be life-threatening. New biological drugs to treat cancer can cause autoimmune hypophysitis and hypopituitarism; therefore, oncologists and endocrinologists should be vigilant and work together to optimise patient outcomes.
