Cancer in children and adolescents in Spain: incidence, treatment setting and provider specialty

Childhood and Adolescent Central Nervous System Tumours in Spain: Incidence and Survival over 20 Years: A Historical Baseline for Current Assessment

BACKGROUND

Central nervous system (CNS) neoplasms are highly frequent solid tumours in children and adolescents. While some studies have shown a rise in their incidence in Europe, others have not. Survival remains limited. We addressed two questions about these tumours in Spain: (1) Is incidence increasing? and (2) Has survival improved?

METHODS

This population-based study included 1635 children and 328 adolescents from 11 population-based cancer registries with International Classification of Childhood Cancer Group III tumours, incident in 1983-2007. Age-specific and age-standardised (world population) incidence rates (ASRws) were calculated. Incidence time trends were characterised using annual percent change (APC) obtained with Joinpoint. Cases from 1991 to 2005 (1171) were included in Kaplan-Meier survival analyses, and the results were evaluated with log-rank and log-rank for trend tests. Children's survival was age-standardised using: (1) the age distribution of cases and the corresponding trends assessed with Joinpoint; and (2) European weights for comparison with Europe.

RESULTS

ASRw 1983-2007: children: 32.7 cases/106; adolescents: 23.5 cases/106. The overall incidence of all tumours increased across 1983-2007 in children and adolescents. Considering change points, the APCs were: (1) children: 1983-1993, 4.3%^ (1.1; 7.7); 1993-2007, -0.2% (-1.9; 1.6); (2) adolescents: 1983-2004: 2.9%^ (0.9; 4.9); 2004-2007: -7.7% (-40; 41.9). For malignant tumours, the trends were not significant. 5-year survival was 65% (1991-2005), with no significant trends (except for non-malignant tumours).

CONCLUSIONS

CNS tumour incidence in Spain was found to be similar to that in Europe. Rises in incidence may be mostly attributable to changes in the registration of non-malignant tumours. The overall malignant CNS tumour trend was compatible with reports for Southern Europe. Survival was lower than in Europe, without improvement over time. We provide a baseline for assessing current paediatric oncology achievements and incidence in respect of childhood and adolescent CNS tumours.

Physical Activity Promotion Programmes in Childhood Cancer Patients and Their Impact on Fatigue and Pain: A Systematic Review

Cancer is one of the main causes of death in children, however, the techniques and interventions applied allow the cure of 80% of diagnosed cases. The aim of this review was to determine the benefits of a health and physical activity promotion programme to reduce pain and fatigue symptoms in children and adolescents with cancer. The databases PubMed, Embase, Scopus, Cochrane, Web of Science and PEDro were searched between December 2020 and January 2021 to elaborate this review, using the keywords child, cancer, exercise, fatigue and pain. The review was preregistered in PROSPERO (ID CRD42021262183). Six studies, out of 937 identified at baseline, were finally included in the review: four randomised controlled trials and two quasi-experimental studies. The total sample size of all the included studies was of 474 participants with very different types of cancer and evolution, and outcome variables were pain, fatigue, physical activity level, self-efficacy and quality of life. A health and physical activity promotion programme seems to improve fatigue in paediatric cancer patients and survivors, but no significant results were found related to pain.

Comparison of Incidence and Outcomes of Neuroblastoma in Children, Adolescents, and Adults in the United States: A Surveillance, Epidemiology, and End Results (SEER) Program Population Study

Background

This United States (U.S.) population study aimed to compare the incidence of neuroblastoma and outcomes in children, adolescents, and adults using the Surveillance, Epidemiology, and End Results (SEER) program database.

Material/Methods

Patients with neuroblastoma were identified in the SEER database from 1975 to 2013. According to the age at diagnosis, patients were divided into “Children” (≤14 years old) and “Adolescents/Adults” group (>14 years old). Then, comparisons in basic characteristics, incidence rates (IRs) and long-term survival outcomes between patients in 2 groups were made.

Results

A total of 4280 patients were identified, including 3998 children and 282 adolescent/adult patients. Adolescent/adult patients were more likely to have localized diseases than children and to be diagnosed with ganglioneuroblastoma (all P<0.05). The IR of neuroblastoma presented with upward and downward trends in children and adolescent/adult populations, respectively. Adolescents/adults had worse overall survival (OS) than children despite the earlier tumor stage. Lastly, multivariate Cox proportional hazards analyses showed that tumor stage, histology, sequence of primary malignancy, primary site, the administration of surgery, and treatment era were prognostic factors for children, and sequence of primary malignancy, primary site, undergoing surgery, and treatment era were tightly related to OS in adolescent/adult patients.

Conclusions

Analysis of the SEER program database between 1975 to 2013 showed that in the U.S., the incidence of neuroblastoma in children increased, but the incidence decreased in adolescents and adults. There was a trend for improved overall survival in all age groups despite the increased stage at presentation in children.

[Cancer in the first 18 months of life]

INTRODUCTION

Oncological-haematological disease continues to be the first cause of non-traumatic mortality in childhood, as well as a significant cause of morbidity. The patient less than 18-months-old has special clinical, diagnostic, and therapeutic features that all paediatricians are interested in determining, with the aim of achieving greater survival and a lower morbidity throughout the lives of their patients.

MATERIAL AND METHODS

A retrospective, descriptive study was carried out using the clinical, diagnostic, and therapeutic variables in patients less than 18-months-old diagnosed with an oncological-haematological that received chemotherapy in a Paediatric Oncology Unit between January 2007 and August 2019.

RESULTS

A total of 72 patients were diagnosed with 76 cancers that required chemotherapy. The most common cancer was leukaemia (21 patients), followed by neuroblastoma (15 patients), and tumours of the central nervous system (12 patients). The presentation of "life-threatening symptoms" was seen in 20.8% of cases, particularly in tumours of neural origin (13/15). Although 18% of patients showed no symptoms on diagnosis, just over half (51%) of the diagnoses took place in the "advanced stages". Particularly in the case of solid tumours in which 23.6% were diagnosed with metastases. A significant percentage of genetic alterations implicated in the aetiopathogenesis of the different cancers were found.

CONCLUSIONS

Cancer in the first stages of life is a diagnostic and therapeutic challenge due to its phenotypical diversity, its genetic load, and its therapeutic difficulties. Knowledge of its particular features is essential for its early and effective approach.

The Effect of the Family-Centered Empowerment Model (FCEM) on the Care Burden of the Parents of Children Diagnosed with Cancer

Background: Families face multiple problems after their children are diagnosed with cancer. This study aims to determine the effect of the Family-Centered Empowerment Model (FCEM) on the care burden of the parents of children, diagnosed with cancer. Methods: This quasi-experimental study was conducted with 78 parents, having children with cancer. The FCEM was implemented in the intervention group in four stages, namely perceived a threat, self-efficacy, educational participation, and evaluation during four sessions of 20-40 minutes. The control group only received the usual care. The burden of care of the control and intervention groups were measured one month after filling out the initial questionnaire, and one month after the end of the intervention, respectively. Results: The two groups were similar in terms of demographic variables and level of burden of care. However, a statistically significant difference was observed between the two groups, in terms of the level of burden (p<0.001). Conclusion: The results of this study showed that the empowerment of parents of children with cancer has an impact on reducing their care burden, and using this empowerment model is recommended to the treatment team, especially nurses.
