Guidelines for Long-Term Follow-Up after Childhood Cancer: Practical Implications for the Daily Work

[Risk of malnutrition and food insecurity in pediatric cancer patients. The NutriCare Study]

INTRODUCTION

cancer and its treatments have been associated with poor nutritional status in children and adolescents.

OBJECTIVE

to establish the nutritional risk of pediatric patients and the degree of food and nutritional insecurity in the homes of children and adolescents with cancer who have been hospitalized in a high complexity pediatric oncology center.

METHODS

a prospective observational study conducted at the Fundación Hospital Pediátrico la Misericordia - HOMI. It included a sample of 41 children and adolescents aged 0 to 17 years and 11 months with a diagnosis of childhood cancer during the study period. The participants recruited during hospitalization had the application of the SCAN nutritional screening tool for childhood cancer, Spanish version, validated in HOMI and the Latin American and Caribbean Scale of Food and Nutritional Security - ELCSA, adapted and validated in Colombia.

RESULTS

76 % (n = 31) of the patients were classified as "At risk of malnutrition" using the SCAN-SP nutritional screening tool. It was observed that 56 % of all households had a proportion of food insecurity, of which the classification of food (in)security was mild in 29 %, moderate in 20 % and severe in 7 % of households with children under 18 years of age.

CONCLUSION

in the framework of the nutritional care process, it is important to take into account factors that include a complete nutritional risk assessment and evaluation that includes the measurement of food security.

Health-Related Quality of Life of Adolescent and Young Adult-Aged Childhood Cancer Survivors in a South African Cohort: A Pilot Study Using the Minneapolis-Manchester Quality of Life Instrument

Purpose: We investigated the health-related quality of life (HRQoL) of an adolescent and young adult (AYA)-aged South African childhood cancer survivor (CCS) cohort. Methods: Participants completed the Minneapolis-Manchester Quality of Life adolescent and adult forms. The overall Cronbach's alpha coefficients were 0.81 (adolescent form) and 0.92 (adult form). The scale-level content validity indexes were acceptable (0.88 and 0.89 for the adolescent and adult forms, respectively). The total domain and overall HRQoL scores were calculated. Results: Sixty-two survivors completed the adolescent form and 30 completed the adult form. The median age was 17.5 years (range 13-34 years), and the median time from diagnosis was 12 years (male:female ratio 1:1.2). Risk factors for poor physical functioning included age at study visit (p = 0.015), solid tumor diagnosis (p = 0.012), radiotherapy (p = 0.021), and surgery (p = 0.006). Six or more late effects impacted most domains negatively; severe late effects (p = 0.020) decreased physical functioning. Lower socioeconomic status was associated with poorer physical (p = 0.006) and cognitive (p = 0.047) functioning. The adult form cohort had poorer psychological (p = 0.014) and social functioning (p = 0.005) and body image (p = 0.016) than the adolescent form cohort. Conclusion: Older age, radiotherapy, surgery, solid tumor diagnosis, and the number and severity of late effects negatively influenced HRQoL in AYA-aged CCSs. A long-term follow-up (LTFU) risk stratification system should include HRQoL status to assist with holistic LTFU care.

A Multimodal Lifestyle Psychosocial Survivorship Program in Young Cancer Survivors: The CARE for CAYA Program-A Randomized Clinical Trial Embedded in a Longitudinal Cohort Study

Importance

There is a lack of trials examining the effect of counseling interventions for child, adolescent, and younger adult (CAYA) cancer survivors.

Objective

To assess lifestyle habits and the psychosocial situation of CAYAs to determine the efficacy of needs-based interventions in the CARE for CAYA program (CFC-P).

Design, Setting, and Participants

The CFC-P was conducted as a multicenter program in 14 German outpatient clinics, mainly university cancer centers. Recruitment began January 1, 2018; a randomized clinical trial was conducted until July 15, 2019; and intervention was continued as a longitudinal cohort study until March 31, 2021. Data preparation was conducted from April 1, 2021, and analysis was conducted from August 14, 2021, to May 31, 2022. Herein, predefined confirmatory analyses pertain to the RCT and descriptive results relate to the overall longitudinal study. Data analysis was based on the full analysis set, which is as close as possible to the intention-to-treat principle.

Intervention

A comprehensive assessment determined needs in physical activity, nutrition and psychooncology. Those with high needs participated in 1 to 3 modules. In the RCT, the IG received 5 counseling sessions plus newsletters, while the control group CG received 1 counseling session.

Main Outcomes and Measures

The primary outcome was the change in the rate of CAYAs with high needs at 52 weeks. Secondary outcomes were feasibility, modular-specific end points, satisfaction, quality of life, and fatigue.

Results

Of 1502 approached CAYAs aged 15 to 39 years, 692 declined participation. Another 22 CAYAs were excluded, resulting in 788 participants. In the randomized clinical trial, 359 CAYAs were randomized (intervention group [IG], n = 183; control group [CG], n = 176), and 274 were followed up. In the RCT, the median age was 25.0 (IQR, 19.9-32.2) years; 226 were female (63.0%) and 133 male (37.0%). After 52 weeks, 120 CAYAs (87.0%) in the IG and 115 (86.5%) in the CG still had a high need in at least 1 module (odds ratio, 1.04; 95% CI, 0.51-2.11; P = .91). Both groups reported reduced needs, improved quality of life, reduced fatigue, and high satisfaction with the CFC-P.

Conclusions and Relevance

In this randomized clinical trial, the implementation of a lifestyle program in this cohort was deemed necessary, despite not meeting the primary outcome. The interventions did not alter the rate of high needs. The results may provide guidance for the development of multimodal interventions in the follow-up care of CAYAs.

VersKiK qualitative study design: actual follow-up needs of paediatric cancer survivors, their informal caregivers and follow-up stakeholder perceptions in Germany

INTRODUCTION

This article presents the study design of the qualitative part of the VersKiK study (Long-term care, care needs and wellbeing of individuals after cancer in childhood or adolescence: study protocol of a large scale multi-methods non-interventional study) aiming to explore actual follow-up needs of childhood and adolescence cancer survivors and their informal caregivers, gaps in current follow-up care provision and trajectories of cancer survivors' transition from paediatric to adult healthcare.

METHODS AND ANALYSIS

We will conduct up to 30 interviews with survivors of childhood and adolescence cancer and their informal caregivers with up to 20 participant observations of follow-up appointments. The results of these will be discussed in up to four focus groups with healthcare professionals and representatives of self-help groups. The study design aims to evaluate follow-up care after childhood cancer considering perspectives from survivors, their informal caregivers as well as healthcare providers. The combination of different data sources will allow us to get an in-depth understanding of the current state of follow-up care after paediatric cancer in Germany and to suggest recommendations for care improvement.

ETHICS AND DISSEMINATION

The VersKiK study was approved by the Ethics Committee Otto von Guericke University on 2 July 2021 (103/21), by the Ethics Committee of Johannes Gutenberg University Mainz on 16 June 2021 (2021-16035), by the Ethics Committee University of Lübeck on 10 November 2021 (21-451), by the Ethics Committee University of Hospital Bonn on 28 February 2022 (05/22). For each part of the qualitative study, a separate written informed consent is prepared and approved accordingly by the ethics committees named above.

VersKiK: Study protocol of an observational registry-based study on the current state of follow-up care and adherence to follow-up guidelines after cancer in childhood or adolescence

BACKGROUND

This article describes the study design of the quantitative part of the VersKiK study, The primary objectives of this study are to examine the occurrence of late effects in survivors of childhood or adolescent cancer (module 1), investigate health-related vulnerabilities and medical service utilization within this survivor group (modules 1 and 3), and assess the alignment between documented follow-up care for cardiological and audiological late effects with guideline recommendations, along with evaluating the extent of adherence among paediatric cancer survivors (module 3).

METHODS

This is a non-interventional retrospective observational cohort study. It is based on stochastically linked insurance claims data from approximately 150,000 statutory insured persons with information concerning around 25,000-30,000 cancer survivors recorded in the German Childhood Cancer Register (GCCR). To explore adherence to selected follow-up guidelines, intention to treat treatment data from clinical study groups for particular diagnostic entities will be additionally included.

DISCUSSION

The growing group of survivors after cancer in childhood and adolescence is representing a special population with an increasing demand for life-long healthcare services through relative high probability of late effects. Currently, there is a limited evidence in Germany on utilization of corresponding medical services and adherence to follow-up guidelines. With this study design, we are aiming to address these gaps and, consequently, suggest improvements to existing follow-up guidelines and follow-up care provision in Germany.

Proposal of a diagnostic algorithm for radiation-induced dropped head syndrome in long-term childhood cancer survivors based on a prospective study in a specialized clinical setting and a review of the literature

PURPOSE

To prospectively assess the incidence of Dropped Head Syndrome (DHS) in childhood cancer survivors (CCS) and to develop and evaluate a diagnostic algorithm for DHS.

METHODS

A systematic literature search for DHS in combination with neck radiotherapy (RT) exposure was performed. Analyses and a combination of the most common examination methods were integrated into a diagnostic algorithm. Almost all CCSs visiting the local late effects clinic between May 2020 and April 2022 were included in the study. CCS exposed to neck RT with doses ≥ 19 Gy received standardized clinical and neurological assessment and, in case of abnormal results, an MRI scan to confirm muscle atrophy.

RESULTS

Two hundred and five CCS were included of whom 41 received RT to the neck with ≥ 19 Gy. In the entire cohort and in the subgroup receiving RT, 2.4% and 12% of CCS were affected by DHS, respectively. Results of clinical and neurological assessment correlated well with MRI results. Neck circumference and neck/thigh ratio were lower after neck RT. Over 50% of CCS experienced neck disability and pain.

CONCLUSIONS

A relevant proportion of CCS exposed to neck RT is affected by DHS. High concordance of MRI results with the neurological examination supports the clinical value of the diagnostic algorithm. Measurement of neck circumference might be an easy tool for assessment of neck muscle atrophy in survivors at risk.

IMPLICATIONS FOR CANCER SURVIVORS

Integration of a diagnostic algorithm for DHS in standard long-term follow-up care facilitates diagnosis as well as initiation of early treatment and obviates the need for invasive examinations.

Implementation of a clinical long-term follow-up database for adult childhood cancer survivors in Germany: a feasibility study at two specialised late effects clinics

PURPOSE

Childhood cancer survivors (CCS) are at risk for increased morbidity and reduced quality of life associated with treatment-related late effects. In Germany, however, only a few of the more than 40,000 CCS registered in the German Childhood Cancer Registry (GCCR) currently benefit from adequate clinical long-term follow-up (LTFU) structures. To establish a comprehensive knowledge base on CCS' long-term health in Germany, a database was developed in cooperation with the GCCR. Following a first evaluation phase at two German university centres, this database will be implemented more widely within Germany allowing longitudinal documentation of clinical LTFU data.

METHODS

The feasibility study cohort comprised 208 CCS aged 18 or older whose medical, mental and psychosocial health data were collected during routine LTFU or first clinic visits in adult care. CCS were enrolled from 04/2021 to 12/2022, and data entry was completed by 03/2023. Descriptive data analysis was conducted. All CCS were stratified into three risk groups (RG) based on their individual risk for developing late effects resulting from their respective diagnoses and treatments.

RESULTS

Chronic health conditions of various organ systems associated with late and long-term effects of cancer therapy affected CCS in all RG supporting the clinical relevance of risk-adapted LTFU. Enrolment into the database was feasible and broadly accepted amongst CCS.

CONCLUSION

Implementation of a clinical follow-up care infrastructure and database in Germany will pave the way to collect clinically evaluated and regularly updated health data of potentially over 40,000 German CCS and facilitate future national and international cooperation.

Contraceptive methods and fertility testing in young adult survivors of childhood cancer

PURPOSE

Reproductive health is important, but often neglected in cancer survivorship care. This study explored contraceptive use and factors associated with fertility testing among young adult survivors of childhood cancer in Germany.

METHODS

Young adult survivors of childhood cancer were identified through the German Childhood Cancer Registry and completed a mailed survey. Survivors were queried regarding contraceptive use, reproductive goals, uncertainty about fertility, and completion or interest in fertility testing. Multivariable stepwise logistic regression models were used to calculate Odds Ratios (OR) and 95% confidence intervals (CI) as a means of identifying factors associated with completion of and interest in fertility testing.

RESULTS

Survivors (N = 472; 57.8% female; aged 23.3 ± 1.5 years, and 14.9 ± 5.0 years from diagnosis), reported high rates of contraceptive use, including 61.2% using a single method, 30.6% dual methods, and 8.1% no/less effective methods. Few survivors had completed fertility testing (13.0%), although 58.8% were interested. Having been diagnosed during adolescence (OR = 2.66, 95%CI: 1.39-5.09), greater uncertainty about fertility (OR = 1.16, 95%CI: 1.03-1.31), and use of dual contraceptive methods (OR = 1.94, 95%CI: 1.02-3.69) were associated with having completed fertility testing. Factors associated with interest in fertility testing included goals of wanting to have children (OR = 7.76, 95%CI: 3.01-20.04) and greater uncertainty about fertility (OR = 1.19 95%CI: 1.06-1.33).

CONCLUSION

In this sample of young adults who survived childhood cancer, most reported contraceptive use. Few survivors had completed fertility testing, although more than half were interested. Interventions are needed to address potential barriers to fertility testing and help survivors manage fertility-related uncertainty.

Impact of Volumetric Dosimetry on the Projected Cost of Radiation-Related Late Effects Screening After Childhood Cancer: A Real-World Cohort Analysis

BACKGROUND

Screening guidelines for childhood cancer survivors treated with radiation currently rely on broad anatomic irradiated regions (IR) to determine risk for late effects. However, contemporary radiotherapy techniques use volumetric dosimetry (VD) to define organ-specific exposure, which supports more specific screening recommendations that could be less costly.

PATIENTS AND METHODS

This was a cross-sectional study of 132 patients treated with irradiation at Children's Hospital Los Angeles from 2000 to 2016. For 5 key organs (cochlea, breast, heart, lung, and colon), radiation exposure was determined retrospectively using both IR and VD methods. Under each method, Children's Oncology Group Long-Term Follow-Up Guidelines were used to identify organs flagged for screening and recommended screening tests. Projected screening costs incurred under each method were computed through age 65 using insurance claims data.

RESULTS

Median age at the end of treatment was 10.6 years (range, 1.4-20.4). Brain tumor was the most common diagnosis (45%) and head/brain the most common irradiated region (61%). For all 5 organs, use of VD rather than IR resulted in fewer recommended screening tests. This led to average cumulative estimated savings of $3769 (P = .099), with significant savings in patients with CNS tumors (P = .012). Among patients with savings, average savings were $9620 per patient (P = .016) and significantly more likely for females than males (P = .027).

CONCLUSION

Use of VD to enhance precision of guideline-based screening for radiation-related late effects permits fewer recommended screening tests and generates cost-savings.

Updated International Guidelines for Survivorship Care after Pediatric Cancer: Practice Implications in a German and Austrian Comprehensive Care Network

BACKGROUND

Timely diagnosis of treatment-related chronic health conditions in childhood cancer survivors (CCS) may result in reduced long-term morbidity and mortality. Evidence-based guidelines serve as a tool to implement risk-adapted screening examinations in long-term follow-up (LTFU) of CCS.

SUMMARY

New international LTFU guidelines from the last 3 years have been reviewed and included into a practical LTFU tool in order to provide an updated summary of LTFU recommendations. The inclusion of 13 new LTFU guidelines as well as 25 pragmatic recommendations resulted in an updated LTFU plan for implantation in daily practice. Special consideration of psychosocial and mental health aspects as well as recommendations for pregnant CCS complement holistic LTFU care.

KEY MESSAGES

Risk-adapted LTFU in CCS offers the possibility for early detection and treatment of late effects. As these LTFU recommendations aim at asymptomatic individuals, benefits and potential risks of regular screening examinations have to be carefully balanced. Implementation of current evidence-based guidelines in clinical practice as well as the development of new application tools such as the Survivorship Passport can contribute to an individualized LTFU approach in order to ensure long-term health and quality of life in CCS.

Current Status and Physicians' Perspectives of Childhood Cancer Survivorship in Korea: A Nationwide Survey of Pediatric Hematologists/Oncologists

BACKGROUND

Data on the status of long-term follow-up (LTFU) care for childhood cancer survivors (CCSs) in Korea is lacking. This study was conducted to evaluate the current status of LTFU care for CCSs and relevant physicians' perspectives.

METHODS

A nationwide online survey of pediatric hematologists/oncologists in the Republic of Korea was undertaken.

RESULTS

Overall, 47 of the 74 board-certified Korean pediatric hematologists/oncologists currently providing pediatric hematology/oncology care participated in the survey (response rate = 63.5%). Forty-five of the 47 respondents provided LTFU care for CCSs five years after the completion of primary cancer treatment. However, some of the 45 respondents provided LTFU care only for CCS with late complications or CCSs who requested LTFU care. Twenty of the 45 respondents oversaw LTFU care for adult CCSs, although pediatric hematologists/oncologists experienced more difficulties managing adult CCSs. Many pediatric hematologists/oncologists did not perform the necessary screening test, although CCSs had risk factors for late complications, mostly because of insurance coverage issues and the lack of Korean LTFU guidelines. Regarding a desirable LTFU care system for CCSs in Korea, 27 of the 46 respondents (58.7%) answered that it is desirable to establish a multidisciplinary CCSs care system in which pediatric hematologists/oncologists and adult physicians cooperate.

CONCLUSION

The LTFU care system for CCS is underdeveloped in the Republic of Korea. It is urgent to establish an LTFU care system to meet the growing needs of Korean CCSs, which should include Korean CCSs care guidelines, provider education plans, the establishment of multidisciplinary care systems, and a supportive national healthcare policy.

[Screening for late effects after childhood cancer in adults]

In recent decades, long-term survival after childhood/adolescent cancer has steadily improved and 5-year survival rate is over 80% for most entities. Studies have shown that more than two thirds of these long-term survivors develop new diseases associated with the treatment, so-called late effects, that occur years to decades after the end of cancer therapy. Risk-adapted screening examinations are recommended to ensure early diagnosis and treatment of late effects. These examinations are offered by interdisciplinary long-term follow up (LTFU) teams.In order to facilitate standardized LTFU worldwide, the International Guideline Harmonization Group (IGHG) was founded from representatives of various disciplines involved in LTFU. The evidence-based follow-up guidelines created by this group replace national recommendations.Numerous new IGHG guidelines have been published in recent years. The following topics are presents as examples:Breast Cancer Screening: Due to an increased risk of breast cancer, female patients should be included in intensified screening programs after thoracic radiotherapy. This now includes patients exposed to a radiation dose of 10 Gray and more.Bone density: Various cancer treatments elevate the risk for low bone density. Therefore, these patients should receive early bone density measurement.Mental health and fatigue: Mental illness and Fatigue can occur years to decades after cancer and should be regularly addressed during follow-up.

Psychological distress of adolescent and young adult childhood cancer survivors in a South African cohort

BACKGROUND

We investigated psychological distress in a South African childhood cancer survivor (CCS) cohort.

METHODS

Adult CCSs treated at Tygerberg Hospital, Cape Town, completed the Brief Symptom Inventory-18. Internal consistency was acceptable: Cronbach's alpha values were 0.91 (Global Severity Index (GSI)), 0.85 (depression), 0.83 (somatization), and 0.75 (anxiety). We compared results utilizing different case rules (GSI T scores of ≥50, ≥57, and ≥63) for the identification of psychological distress.

RESULTS

Forty CCSs (median age 24 years; median follow-up period 16 years) participated. Most (58%; 23 out of 40) completed school or tertiary education, were unmarried (90%; 36 out of 40), and unemployed (59.5%; 22 out of 37). The diagnoses included hematological malignancies (65%; 26 out of 40) and solid tumors (35%; 14 out of 40). The GSI T scores of ≥63, ≥57, and ≥50 identified 10% (four out of 40), 32.5% (13 out of 40), and 45% (18 out of 40) of survivors with psychological distress, respectively. Radiotherapy (odds ratio (OR) 4.6; p = .035), presence of ≥six late effects (OR 7.5; p = .026), and severe late effects (OR 6.6; p = .024) were significant risk factors (GSI T score ≥57). Follow-up period of 11-20 years (OR 7.3; p = .034) was significant for a GSI T score ≥50.

CONCLUSION

This South African CCS cohort had higher levels of psychological distress utilizing the GSI T score ≥50 and ≥57 case rules than reported in the literature. Most were unmarried or unemployed. Significant contributing factors were radiotherapy, number and severity of late effects, and follow-up period. CCSs must be screened for psychological distress.

Validation of the Three-Item Insomnia Severity Index Short Form in Young Adult Cancer Survivors: Comparison with a Structured Diagnostic Interview

Chronic insomnia affects ∼25% of young adult cancer survivors (YACS) but is often overlooked in routine follow-up. A recently introduced three-item version of the Insomnia Severity Index (ISI-3) was compared with a diagnostic interview (SCID-5) in 250 YACS (ages 18-40) to evaluate its validity in this population. The ISI-3 had good discrimination compared with the SCID-5 (area under the receiver operating characteristic curve = 0.88). Although no ISI-3 cutoff met study criteria for both sensitivity (≥0.85) and specificity (≥0.75), an ISI-3 cutoff of ≥4 had high sensitivity (94%) and moderate specificity (70%), and is recommended as the first step in a two-step screening procedure.

Comparison of psychosocial adaptations among childhood cancer survivors, their siblings and peers in Taiwan

PURPOSE

This study aimed to understand the difference in psychosocial adaptation among childhood cancer survivors, their healthy siblings and peers, and the factors affecting the psychosocial adaptation of these cancer survivors.

DESIGN AND METHODS

A total of 222 children (ages 8-17) including childhood cancer survivors, their siblings, and healthy peers participated in this cross-sectional study. All the children completed the anxiety and quality of life scales for their age groups.

RESULTS

Anxiety levels and quality of life were similar among the childhood cancer survivors, their siblings, and their peers. The anxiety of elementary school-age survivors of acute leukemia was higher than that of those with solid tumors. Elementary school-age survivors who completed three or more years of treatment had lower anxiety than those who completed treatment within the three years. For adolescent survivors, the higher their body mass index, the higher their anxiety, which was associated with low quality of life. Those diagnosed with anxiety and at an older age had lower quality of life.

CONCLUSIONS

Although there were no differences in survivors' psychosocial adaptation compared to their siblings and healthy peers, more than half of these adolescents had moderate to severe anxiety. Future study may need to explore the causes of their anxiety.

PRACTICE IMPLICATIONS

During the follow-ups of the childhood cancer survivors, age-specific adaptive strategies can be discussed to reduce their anxiety and improve their quality of life.

Knowledge of Required Medical Surveillance Among Adolescent and Young Adult Survivors of Childhood Cancer

PURPOSE

Adolescent and young adult (AYA) cancer survivors experience treatment-related late effects so guidelines recommend providing a treatment summary, yearly follow-up, and risk-adapted testing. AYA survivors' knowledge of surveillance follow-up was studied.

RESULTS

Survey responses for 73 AYAs were stratified: low (0 to 1 correct; n=18; 24.7%) versus high knowledge (2 to 4 correct; n=55; 75.3%) of their required testing. Patient-reported Outcomes Measurement Information System (PROMIS) scores fell within average ranges for participant age ( T -scores: 52.4 for physical function, 49.3 for anxiety, 46.3 for depression, and 44.7 for fatigue). Younger age at survivorship visit was a significant predictors of improved knowledge scores.

CONCLUSION

Despite attendance at a survivorship clinic, minority of participants (9.5%) demonstrated complete knowledge of surveillance testing needs. Most survivors are aware of some of their surveillance needs. PROMIS scores were not associated with surveillance knowledge.

Long-term care, care needs and wellbeing of individuals after cancer in childhood or adolescence (VersKiK): study protocol of a large scale multi-methods non-interventional study

BACKGROUND

It has been shown previously that a relevant proportion of childhood cancer survivors suffers from late effects, which are often directly related to the cancer itself or its therapy, resulting in particular follow-up needs, additionally burdening healthcare systems. Being diagnosed with cancer at a vulnerable stage of development, this group of cancer survivors is at comparatively higher risk of relapse or subsequent cancer. Although national and international follow-up guidelines based on treatment modalities have been developed, their implementation seems to leave room for improvement. Additionally, they lack a sufficient consideration of the survivors' psychosocial needs, affecting their adherence to them. The aim of the VersKiK study is to provide representative information on late effects in childhood and adolescence cancer survivors in Germany. The main research objectives are: (1) to describe the state of follow-up care among survivors after a cancer diagnosis in childhood or adolescence; (2) to quantify the occurrence of late effects among this group of survivors; (3) to examine the adherence to selected audiological and cardiological follow-up guidelines and to identify factors affecting it; (4) to explore actual follow-up needs of paediatric cancer survivors; (5) to review selected follow-up guidelines with the aim to improve and expand them.

METHODS

VersKiK is designed as a mixed-methods non-interventional study. We will use claims data from statutory health insurance companies in combination with individually linked population-based registry data from the German Childhood Cancer Registry (GCCR). This data base will permit us to quantify diagnoses and procedures in comparison to the general population as well as the adherence to existing follow-up guidelines. Additional information will be obtained through interviews with childhood and adolescence cancer survivors and their informal caregivers, as well as in focus groups with healthcare professionals.

DISCUSSION

The present study aims to research the actual needs of individuals after cancer diagnosis and treatment in childhood or adolescence - physical, psychological and organisational - in order to improve existing follow-up guidelines. These improvements might further positively affect not only actual care provided to paediatric cancer survivors, but also benefit healthcare systems in general while decreasing consequent medical visits in this group of patients.

Healthy lifestyles in childhood cancer survivors in South Korea: a comparison between reports from children and their parents

Purpose

This study investigated childhood cancer survivors' behavior related to a healthy lifestyle during their survival period by comparing reports between childhood cancer survivors and their parents.

Methods

In this comparative descriptive study, a survey was conducted with a 33-item questionnaire and one open-ended question about areas for improvement. The participants comprised 69 childhood cancer survivors and 69 of their parents, for a total of 138.

Results

The total mean healthy lifestyle score, on a 4-point Likert scale, reported by childhood cancer survivors was 2.97, while that reported by their parents was 3.03. No significant differences in children's healthy lifestyles were found between childhood cancer survivors' and their parents' reports (t=0.86, p=.390). For the open-ended question, the main keywords based on the results of degree and eigenvector centrality were "exercise", "unbalanced diet", and "food". These keywords were present in both the children's and parents' responses.

Conclusion

Obtaining information on childhood cancer survivors' healthy lifestyles based on reports from themselves and their parents provides meaningful insights into the improvement of health care management. The results of this study may be used to develop and plan healthy lifestyle standards to meet childhood cancer survivors' needs.

'Trying to catch up with life': The expectations and views of adolescent survivors of childhood acute lymphoblastic leukaemia about long-term follow-up care: A qualitative research

OBJECTIVE

The aim of this study was to explore adolescent survivors' views and expectations about long-term follow-up care.

METHODS

Semi-structured, in-depth interviews were conducted with 16 adolescent survivors of childhood acute lymphoblastic leukaemia. Survivors who had completed treatment at least 2 years ago were involved in the study. Interviews were audio-recorded and transcribed verbatim. An inductive thematic approach was used to analyse the data.

RESULTS

Four main themes and sub-themes were identified from the analysis as follows: information needs with three sub-themes 'long-term follow-up, healthy life and social life', support needs with three sub-themes 'psychosocial (peer relations etc.), school related and social-emotional (fear of relapse, body image, self-esteem, etc.)', perceived benefits with two sub-themes 'social-emotional and related to long-term follow-up' and perceived barriers 'medical-hospital related and social life'.

CONCLUSIONS

Adolescent survivors mainly need support in terms of psychosocial aspects: self-esteem-body image, school, peer relations and social activities during follow-up. Identified barriers related to follow-up were school absence and not able to participate social activities. Adolescents specify health promotion approaches as benefits aspects of follow-up. The findings of this study will guide nurses in the long-term follow-up care of adolescent survivors of acute lymphoblastic leukaemia and provide an opportunity to plan individualised follow-up care.

A Mixed-Methods Investigation of Medical Follow-Up in Long-Term Childhood Cancer Survivors: What Are the Reasons for Non-Attendance?

As long-term childhood cancer survivors (CCS) are at risk for late effects, ongoing medical care is crucial to detect and treat physical illnesses as early as possible. However, previous research from around the world has shown that many adult survivors did not participate in long-term medical follow-up. This study aimed to provide insight into German survivors’ care situation, with a particular focus on barriers to follow-up care. We investigated a sample of adult CCS (N = 633) (age M = 34.92; SD = 5.70 years) drawn from the German Childhood Cancer Registry’s oldest cohort (> 25 years after diagnosis). Our analyses included data from a standardized medical examination, a self-report questionnaire, and in-depth interviews with a subsample (n = 43). Half of the participants (n = 314, 49.6%) reported participating in some kind of medical follow-up. In a logistic regression analysis, attendance of medical follow-up care was associated with higher age. Reasons for non-attendance were assigned to four categories: lack of information about medical follow-up and/or its purpose (n = 178), termination by the health care provider (n = 53), structural barriers (n = 21), and emotional-motivational aspects (n = 17). The interviews contributed to a better understanding of how these reported barriers played out in the care of individual survivors. Further, they revealed that some survivors currently in medical follow-up had had periods without follow-up care in the past—which were also in many cases related to a lack of information, both on the part of health care providers and CCS themselves. The results indicated that a large proportion of long-term CCS do not receive the recommended follow-up care. Further, there is a great need for more information regarding the aims of long-term medical follow-up and available offers. This is an important prerequisite for CCS to make informed decisions.

Cancer among children, adolescents and young adults in the Hokushin region, Japan, between 2010 and 2015

Adolescents and young adults with cancer encounter age-related challenges. Cancer treatment and support are not always tailored to the needs of each patient due to difficulty in the collection of accurate data. The present study aimed to investigate cancer among children and adolescents and young adults in the four adjacent prefectures of Japan (Toyama, Ishikawa, Fukui and Nagano) by analyzing data from a unique regional cancer database. We retrieved and analyzed the data of pediatric and adolescent and young adult patients aged between 0 and 39 years at cancer diagnosis (including carcinoma in situ), which was registered in the Hokushin Ganpro database between 2010 and 2015. A total of 5718 cases (1571 males and 4147 females) were identified during this period. The overall male-to-female ratio was 1:2.6. There was no distinct difference in the number of cancer cases per 100 000 population between males and females until 19 years of age. The difference became more pronounced after 20 years of age. The number of cancer cases (per 100 000 population) in the 0-14-, 15-19-, 20-29- and 30-39-year age groups was estimated to be 13.4, 14.5, 44.0 and 101.5, respectively. Carcinomas were the most common type of cancer in the adolescents and young adults (15-39 years) population (74%), whereas they were not the predominant cancer type in the pediatric (0-14 years) population. Although further research is needed to understand the needs of adolescents and young adults with cancer, we believe that our findings will help guide efforts to improve the management strategy for adolescents and young adults with cancer.

Late Sequelae of Radiotherapy

BACKGROUND

Approximately half of all patients with tumors need radiotherapy. Long-term survivors may suffer from late sequelae of the treatment. The existing radiotherapeutic techniques are being refined so that radiation can be applied more precisely, with the goal of limiting the radiation exposure of normal tissue and reducing late sequelae.

METHODS

This review is based on the findings of a selective search in PubMed for publications on late sequelae of conventional percutaneous radiotherapy, January 2000 to May 2020. Late sequelae affecting the central nervous system, lungs, and heart and the development of second tumors are presented, and radiobiological mechanisms and the relevant technical and conceptual considerations are discussed.

RESULTS

The current standard of treatment involves the use of linear accelerators, intensity-modulated radiotherapy (IMRT), image-guided and respiratory-gated radiotherapy, and the integration of positron emission tomography combined with computed tomography (PET-CT) in radiation treatment planning. Cardiotoxicity has been reduced with regard to the risk of coronary heart disease after radiotherapy for Hodgkin's lymphoma (hazard ratio [HR] 0.44 [0.23; 0.85]). It was also found that the rate of radiation- induced pneumonitis dropped from 7.9% with conformal treatment to 3.5% with IMRT in a phase III lung cancer trial. It is hoped that neurocognitive functional impairment will be reduced by hippocampal avoidance in modern treatment planning: an initial phase III trial yielded a hazard ratio of 0.74 [0.58; 0.94]. It is estimated that 8% of second solid tumors in adults are induced by radiotherapy (3 additional tumors per 1000 patients at 10 years).

CONCLUSION

Special challenges for research in this field arise from the long latency of radiation sequelae and the need for largescale, well-documented patient collectives in order to discern dose-effect relationships, and take account of cofactors, when the overall number of events is small. It is hoped that further technical and conceptual advances will be made in the areas of adaptive radiotherapy, proton and heavy-ion therapy, and personalized therapy.

Health-Related Quality of Life in European Childhood Cancer Survivors: Protocol for a Study Within PanCareLIFE

Background

Survival after childhood cancer has improved to more than 80% during the last few years, leading to an increased number of childhood cancer survivors. Cancer itself, or its treatment, may cause chronic health conditions, including somatic and mental sequelae, which may affect survivors’ health-related quality of life (HRQoL).

Objective

The project PanCareLIFE aims to establish a large database with comprehensive data on childhood cancer survivors from different European countries, including data on HRQoL. Within PanCareLIFE, this study aims to describe HRQoL in survivors, investigate predictors of HRQoL, and describe the association of HRQoL with hearing and female fertility impairment. This paper describes the design of the HRQoL study, the origin of data, strategies for data collection, and sampling characteristics of survivors from each contributing country.

Methods

A total of 6 institutions from 5 European countries (the Czech Republic, France, Germany, the Netherlands, and Switzerland) provided data on HRQoL assessed with the Short Form 36 and on relevant predictors. The central PanCareLIFE data center aggregated the data and harmonized the variables between the institutions. Survivors were eligible if they received a diagnosis of cancer according to the 12 main groups of the International Classification of Childhood Cancer, 3rd edition, or Langerhans cell histiocytosis; were aged ≤18 years at the time of diagnosis; were residents of the respective country at the time of diagnosis; had survived ≥5 years after cancer diagnosis; were aged ≥18 years at the time of the questionnaire survey; and did not refuse to registration in the national or local childhood cancer cohort.

Results

We identified 24,993 eligible survivors. Of those, 19,268 survivors received a questionnaire and 9871 survivors participated, resulting in response rates of 9871/24,993 (39.50%) of eligible survivors and of 9871/19,268 (51.23%) invited survivors. Most participants were diagnosed with cancer between the ages of 10 and 14 years (3448/9871, 34.93%) or <5 years (3201/9871, 32.43%). The median age was 8 years. Of the 9871 participants, 3157 (31.97%) were survivors of leukemia, 2075 (21.02%) lymphoma, and 1356 (13.7%) central nervous system (CNS) tumors. Most participants (9225/9871, 93.46%) had no history of a subsequent tumor; 77.45% (7645/9871) received chemotherapy with or without other treatments. More than half (5460/9871, 55.31%) were aged 25 to 34 years at the time of the HRQoL study. Participating survivors differed from nonparticipants; participants were more often women, survivors of leukemia or lymphoma, and less frequently, survivors of CNS tumors than nonparticipants.

Conclusions

PanCareLIFE successfully assessed HRQoL and its predictors in 9871 European survivors of childhood cancer. This large population will permit detailed investigations of HRQoL after childhood cancer, particularly the impact of hearing and female fertility impairment on HRQoL.

Management and Surveillance of Short- and Long-Term Sequelae of Radiation Therapy for the Treatment of Pediatric Brain Tumors

Radiation therapy (RT) is a mainstay for the treatment of pediatric brain tumors. As improvements in and sophistication of this modality continue to increase the survival of patients, the long-term sequelae of RT pose significant challenges in the clinical management of this patient population as they transition into adulthood. In this special edition, we review the short- and long-term effects of RT for the treatment of pediatric brain tumors and the necessary surveillance required for follow-up.
