A review of long-term follow-up for survivors of childhood cancer

From Observation to Action: Developing and Pilot-Testing a Communication Tool for Follow-up Consultations with Adolescent Cancer Survivors

Purpose: Efficient physician communication with adolescent cancer survivors (ACS) during follow-up consultations is important to enable survivors to take responsibility for their health. The present study had two aims: to develop a communication tool to enhance structured consultations and improve clinician communication in follow-up consultations, and to pilot-test the tool in physicians' consultations with ACS. Methods: Clinicians and communication experts collaborated closely to develop the 7 Memory Hooks (7MH) communication tool and a corresponding coding scheme for scoring communication behavior in consultations. Thirty-seven follow-up consultations between ACS and physicians were video-recorded (22 before intervention and 15 after intervention). The intervention consisted of a didactic lecture, a group workshop, and individual coaching to provide feedback to physicians on the communication skills observed in the pre-intervention videos. We then compared physicians' communication behavior both before and after intervention. Results: Fourteen physicians participated in the 7MH training. The mean total score on the 7MH scheme was significantly higher post-intervention compared with pre-intervention (p = 0.001). Six behaviors changed significantly after the intervention. At a group level, physicians were more likely to be alone with the adolescent (p = 0.004) and to prepare the patient for transition to adult heath care (p = 0.040). They asked more often about the patients' expectations (p = 0.007) and resources ((p = 0.019). And they acknowledged patients' concerns more often (p = 0.016) but talked significantly less about physical activity (p = 0.012). Conclusion: A physician communication tool, designed bottom-up and developed in collaboration with the clinic, shows promising effects on physicians' communication behavior at follow-up consultations with ACS.

Available, but not always accessible: A nationwide, qualitative study of multidisciplinary healthcare providers' experiences with follow-up care after paediatric brain tumour

OBJECTIVE

Paediatric brain tumour (PBT) survivors face high risks of disabling long-term and late effects. Whether survivors' needs are met in a system with publicly funded services, but in the absence of a formal long-term follow-up model, is uncertain. Empirically based recommendations for a national model are needed. We explored multidisciplinary healthcare providers' (HCP) experiences with providing such care.

METHODS

We conducted five focus-group interviews and five individual interviews with a nationally representative sample of 33 Norwegian HCPs. Focus-group interviews and individual interviews were analysed using systematic text condensation.

RESULTS

Three main themes were identified: (a) 'Providing care above and beyond system constraints', describing a perceived discrepancy between HCPs' knowledge of, and their ability to meet, the survivors' needs. (b) 'System barriers to providing optimal follow-up care', describing a perceived lack of routines for communication and coordination between the HCPs and existing care services. (c) 'Nurses and shared-care to improve care', including empowering nurses and establishing routines for collaborations and areas of responsibilities.

CONCLUSION

The current healthcare system was perceived not to fully meet the survivors' needs. Nurse-led care models, including standardised patient-care pathways, were suggested to increase the accessibility of already-existing services and thus to improve long-term follow-up care.

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.

Late mortality in survivors of childhood cancer in Hungary

The Hungarian Pediatric Oncology Network provides centralized treatment and population-based registration for cases of childhood cancer since 1973. We collected and analized data on late mortality, secondary malignancies and cardiac diseases in survivors (> 5 years) of childhood cancer to evaluate long-term risks. We extracted all solid tumour cases (3,650 followed up for 5–39.3 years, diagnosis: 1973–2008) from the database of the Hungarian Childhood Cancer Registry and checked against the Population Registry. Among the 301 patients who died after 5 years (8.2%) the most common causes of death were progression of primary cancer (52.5%), secondary malignancies (16%) and cardiovascular diseases (8%). Late mortality rates (SMR, total: 35,006 pyrs) showed highly elevated risk of death (SMR: 10.7 95% CI 9–12.4) for the second 5 years of follow up and moderately elevated risk for 10-year survivors (SMR: 3.5 95% CI 3–4.1). Marked differences were detected in the pattern of causes of death between diagnostic groups of primary cancer; with highest risks beyond 10 years for CNS tumours, Hodgkin disease, osteosarcoma and advanced stage neuroblastoma. The longstanding mortality risk for 5-year survivors underlines the need for tailored long-term follow-up and monitoring of late consequences according to the context of different primary diseases of childhood cancer.

Caring for survivors of childhood cancer: it takes a village

PURPOSE OF REVIEW

Over 80% of children diagnosed with cancer are now cured. The burgeoning population of survivors of childhood cancer experiences high rates of morbidity and mortality due to 'late-effects' of treatment. These can be defined as any consequence of treatment that persists beyond or develops after the completion of cancer therapy. Awareness of late-effects is critically important for pediatricians and adult providers alike, as late-effects impact children in proximity to cancer treatment, as well as adults many decades removed. This review presents the importance of lifelong follow-up care for survivors, highlights existing screening guidelines, and reviews various models of survivor care.

RECENT FINDINGS

National and international guidelines have been developed to standardize screening for survivors, and multiple models of survivorship care exist. The optimal model likely depends on individual factors, including the survivor's needs and preferences, as well as local resources. Key strategies for the successful care of survivors include accurate risk-stratification for specific late-effects, individualized screening plans, education of survivors and professionals, clear communication between providers, and well coordinated transition of care across services.

SUMMARY

Early identification and management of late-effects are important for survivors of childhood cancer. Providers should be familiar with the risks for specific late-effects and have access to screening guidelines. The strengths and weaknesses of care models, along with individual circumstances, should be considered in designing the optimal approach to care for each survivor.

Psychosocial interventions for rehabilitation and reintegration into daily life of pediatric cancer survivors and their families: A systematic review

BACKGROUND

The survival rate of childhood cancer patients increased over the past decades. However, even after successful treatment the transition back to normalcy is often a major challenge for the whole family. Therefore, this study aims to provide an overview of psychosocial interventions for childhood cancer survivors and their families in the first years after the end of cancer treatment.

METHODS

We conducted a systematic review following the PRISMA Checklist (Preferred Reporting Items for Systematic Reviews and Meta-Analyses; PROSPERO registration number: CRD42017059782). In November 2016 and September 2017, we searched the databases CINAHL, MEDLINE, PSYNDEX, and Web of Science. We included studies investigating psychosocial interventions for childhood cancer survivors diagnosed under the age of 21, their family members or the family as a whole. Further, we summarized the study characteristics and conducted a narrative synthesis of the results. Finally, we assessed the study quality with the Effective Public Health Practice Project Quality Assessment Tool.

RESULTS

We identified a total of 8215 records based on our database searches and 17 additional records through hand searches. We included 33 articles in the qualitative synthesis. Most of the studies described interventions for the cancer survivor (n = 15). Nine studies investigated interventions for the whole family, and two studies interventions for siblings. The interventions mainly take place in an outpatient group setting (n = 15). Overall, most of the studies reported a significant psychosocial benefit of the interventions. However, the quality of the included studies was limited.

CONCLUSION

In summary, we identified a broad range of different interventions and thus could give a comprehensive overview of existing interventions for childhood cancer survivors and their families. However, there is a necessity for high quality studies. The results may help to optimize health care services that support families with the re-entry into daily life.

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.

"It's just going to a new hospital … that's it." Or is it? An experiential perspective on moving from pediatric to adult cancer services

BACKGROUND

Survivors of childhood cancer will, at some stage, move from pediatric to adult care and/or to a different model of care to continue to receive long-term follow-up. Literature relating to transitional care for childhood onset conditions exists, but little research has been undertaken into transition in a cancer context, specifically from an experiences perspective.

OBJECTIVE

The aim of this study was to report how the process of transition should be considered within the context of young people's entire illness experience and how that experience can impact their transition readiness.

INTERVENTION/METHODS

A qualitative, collective case study approach was adopted. Semistructured interviews were conducted with young people, parents, and healthcare professionals. Young people's oncology case notes were also reviewed.

RESULTS

Data analysis generated a multidimensional and multiple-perspective understanding of the experience of the process of transition. A central orienting theme was identified: the experience of readiness in the context of transition.

CONCLUSIONS

Understanding the multifaceted components of readiness is crucial; readiness should embody people's illness experiences, the numerous and associated losses intertwined with a move from pediatric to adult care, and the simultaneous developmental changes occurring in people's lives.

IMPLICATIONS FOR PRACTICE

The findings provide a meaningful framework to understand the experience of transition from the perspective of young people, parents, and healthcare professionals. These findings could help with the planning and preparation of individualized transitional care pathways for survivors of childhood cancer.

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.

General practitioner involvement in follow-up of childhood cancer survivors: a systematic review

BACKGROUND

An increasing number of childhood cancer survivors need long-term follow-up care. Different models address this problem, including that of follow-up by general practitioners (GP). We describe models that involve GPs in follow-up for childhood cancer survivors, their advantages and disadvantages, clinics that employ these models, and the elements essential to high-quality, GP-led follow-up care.

PROCEDURE

We searched four databases (PubMed [including Medline], Embase, Cochrane, and CINAHL) without language restrictions.

RESULTS

We found 26 publications, which explicitly mentioned GP-led follow-up. Two models were commonly described: GP-only, and shared care between GP and pediatric oncology or late effects clinic. The shared care model appears to have advantages over GP-only follow-up. We found four clinics using models of GP-led follow-up, described in five papers. We identified well-organized transition, treatment summary, survivorship care plan, education of GPs and guidelines as necessary components of successful follow-up.

CONCLUSION

Scarcity of literature necessitated a review rather than a meta-analysis. More research on the outcomes of GP-led care is necessary to confirm the model for follow-up of childhood cancer survivors in the long term. However, with the necessary elements in place, the model of GP-led follow-up, and shared care in particular, holds promise.

Increasing and worsening late effects in childhood cancer survivors during follow-up

Recent advances in childhood cancer treatment have increased survival rates to 80%. Two out of three survivors experience late effects (LEs). From a group of 241 survivors previously described, 193 were followed at the long-term follow-up clinic (LTFC) of Severance Hospital in Korea; the presence of LEs was confirmed by oncologists. We reported the change in LEs during 3 yr of follow-up. The median follow-up from diagnosis was 10.4 yr (5.1-26.2 yr). Among 193 survivors, the percentage of patients with at least one LE increased from 63.2% at the initial visit to 75.1% at the most recent visit (P = 0.011). The proportion of patients having multiple LEs and grade 2 or higher LEs increased from the initial visit (P = 0.001 respectively). Forty-eight non-responders to the LTFC were older and had less frequent and severe LEs than responders at initial visit (all P < 0.05). In multivariate analysis, younger age at diagnosis, older age at initial visit, a diagnosis of a brain tumor or lymphoma, and use of radiotherapy were significant risk factors for LEs (all P < 0.05). Adverse changes in LEs were seen among the survivors, regardless of most clinical risk factors. They need to receive comprehensive, long-term follow up.

After the chemotherapy: potential mechanisms for chemotherapy-induced delayed skeletal muscle dysfunction in survivors of acute lymphoblastic leukaemia in childhood

There is evidence that survivors of childhood cancers, such as acute lymphoblastic leukemia (ALL), have increased rates of long-term skeletal muscle dysfunction. This places them at higher risk of physical restriction and functional impairment as well as potentially contributing to observed increases in cardiovascular disease and insulin resistance in later life. The mechanisms underlying these changes in skeletal muscle are unknown but chemotherapy drugs used in treatment for ALL are strongly implicated. Normal skeletal muscle growth, development, and function are dependent on correctly functioning muscle satellite cells, muscle motor neurons, and muscle mitochondria. Each of these key components is potentially susceptible to damage by chemotherapy in childhood, particularly prolonged courses including repeated administration of combination chemotherapy. If this chemotherapy-induced damage is not fully reversible, impairment of satellite cells, muscle motor innervation, and mitochondria could, either singly or together, lead to the emergence of delayed or persistent skeletal muscle dysfunction many years later. The known effects of individual drugs used in the treatment of ALL are outlined and the need for specific targeted studies to investigate the mechanisms underlying persistent muscle dysfunction in survivors of ALL and other childhood cancers is highlighted.

Psychological adjustment of children with cancer as compared with healthy children: a meta-analysis

Childhood cancer is a life-threatening disease and the cause of great stress for children who suffer from its diagnosis and treatment. The aim of this study was to verify, through meta-analytical tools, whether children in active treatment for cancer differ in their psychological adjustment from healthy children. Ten studies fulfilled the inclusion criteria for the meta-analytic approach. A fixed effects model did not yield significant results, suggesting that there is no evidence for a difference in psychological adjustment between ill and healthy children, inasmuch as the former seem to adjust as well as the latter. Some methodological aspects are also considered, including issues related to the definition of psychological adjustment and its operationalisation and to the relative scarcity of published articles in this particular realm. Moreover, suggestions for future studies are discussed.

Survivor profiles predict health behavior intent: the Childhood Cancer Survivor Study

OBJECTIVES

To determine whether unique groups of adult childhood cancer survivors could be defined on the basis of modifiable cognitive, affective, and motivation indicators. Secondary objectives were to examine to what extent group membership co-varied with more static variables (e.g. demographics, disease, and treatment) and predicted intent for subsequent medical follow-up.

METHODS

Using latent class analysis of data from 978 participants (ages, 18-52 years; mean, 31; and SD, 8) in the Childhood Cancer Survivor Study, we classified survivors according to their worries about health, perceived need for follow-up care, health motivation, and background variables. Intent to participate in medical follow-up, as a function of class membership, was tested using equality of proportions.

RESULTS

The best-fitting model (BIC = 18 540.67, BLMRT = <0.001) was characterized by three distinctive survivor classes (worried, 19%; self-controlling, 26%; and collaborative, 55%) and three significant class covariates (gender, perceptions of health, and severity of late effects). A smaller proportion of survivors in the self-controlling group (81%) than in the worried (90%) (P = 0.015) and collaborative (88%) (P = 0.015) groups intended to obtain a routine medical checkup. A smaller proportion of survivors in the self-controlling group (32%) than in the collaborative (65%) (P = <0.001) and worried (86%) (P = <0.001) groups planned a cancer-related check-up. A smaller proportion of survivors in the collaborative group (65%) than in the worried group (86%) (P = <0.001) were likely to obtain a cancer-related check-up.

CONCLUSIONS

Childhood cancer survivors can be classified according to the modifiable indicators. The classification is distinctive, predicts intent for future medical follow-up, and can inform tailored interventions.

Comprehensive clinical follow-up of late effects in childhood cancer survivors shows the need for early and well-timed intervention

BACKGROUND

Due to recent advances in treatment, nearly 80% of childhood cancer patients become long-term survivors. Studies on the late effects of survivors are under way worldwide. However, data on Asian survivors remain limited.

METHODS

Data on 241 survivors at the Long-term Follow-up Clinic in Severance Hospital, South Korea, were collected and late effects were confirmed by oncologists.

RESULTS

The median follow-up from diagnosis was 7.8 years. Late effects were identified in 59.8% of survivors and 23.2% had two or more late effects. Grade 3 or higher late effects were present in 10.8%. The most common late effects involved endocrine system (29.0%). Late effects were present in 95.7% of brain tumor survivors and 36.0% of Wilms' tumor survivors. Chemotherapy, hematopoietic stem-cell transplantation and radiotherapy were significant factors associated with the number and severity of late effects (P < 0.05). Brain tumor survivors had more severe late effects (P < 0.001), whereas Wilms' tumor survivors had fewer and milder late effects (P < 0.05).

CONCLUSION

The observation that over 50% of cancer survivors suffered from late effects during the short follow-up period and that a high frequency of endocrine late effects was present indicates the need for early and well-timed intervention of the survivors.

Endocrinological analysis of 122 Japanese childhood cancer survivors in a single hospital

With recent improvements in the diagnosis and treatment of cancer, the number of childhood cancer survivors (CCSs) has been increasing in Japan. The importance of quality of life during the lifetime of CCSs has now been recognized, and the late effects of cancer treatments are essential and important issues. In this study we analyzed the endocrinological abnormalities of CCSs by retrospectively evaluating 122 outpatients (62 males and 60 females) who had been referred from pediatric oncologists to our follow-up clinic among 151 CCSs attending our hospital more than two years after their cancer treatment. Follow-up duration varied from 2 to 30 (median 8.0) years. Their average age was 17.3 (range 4-36, median 17.0) years, and 38 patients (31.1%) reached adulthood. Endocrinological abnormalities were found in 82 (67%) of 122 survivors. Gonadal dysfunction was observed in 60 patients (49%). Thirty-nine patients (32%) were short or grew at a slower rate. Twenty-six patients (21%) showed thyroid dysfunction. Other abnormalities were as follows: obesity in 20 patients (16%), leanness in 10 (8%), central diabetes insipidus in 11 (9%) and adrenocortical dysfunction in 9 (7%). Low bone mineral density was observed in 41 (42%) of 98 patients evaluated. These endocrinological abnormalities were caused by the combined effects of cancer itself and various treatments (chemotherapy, radiation therapy, surgery, and hematopoietic stem cell transplantation). Lifetime medical surveillance and continuous follow-up are necessary for CCSs, because treatment-related complications may occur during childhood and many years after the therapy as well. Endocrinologists should participate in long-term follow-up of these survivors in collaboration with pediatric oncologists.
