Exercise Training in Childhood Cancer (FORTEe)

Get Strong to Fight Childhood Cancer: An Exercise Intervention for Children and Adolescents Undergoing Anti-Cancer Treatment

The purpose of this multicenter study is to evaluate a personalised and standardised exercise intervention for children and adolescents undergoing anti-cancer treatment.

Study Overview

• Status: Completed
• Conditions: Pediatric Oncology
• Intervention / Treatment: Behavioral: Exercise training

Detailed Description

In the randomised, controlled FORTEe trial, high evidence for an innovative, patient-centred exercise treatment shall be generated. Supervised exercise training intents to increase muscle strength and reduce muscular atrophy due to bedrest. CRF and HRQoL can be improved and in the future, these benefits may help to fight childhood cancer by increasing therapy efficiency and survival rate. Within the project, digital, innovative technologies such as augmented reality will be developed and applied to make the exercise training more effective, age-adapted and personalised. Moreover, FORTEe will stimulate translational research to provide access to paediatric exercise oncology as a new health care intervention. As a progress beyond the current state-of-the-art, FORTEe has the ambition to implement paediatric exercise oncology as an evidence-based standard in clinical care for all childhood cancer patients across the EU and beyond.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in the score of Cancer-related fatigue during the intervention, after the intervention, and over a 1-year follow-up period compared with baseline	Cancer-related fatigue measured by the Pediatric Quality of Life Inventory (PedsQL) 3.0 Multidimensional Fatigue Scale. The PedsQL Multidimensional Fatigue Scale is composed of 18 items comprising three dimensions. Scores are transformed on a scale from 0 to 100. Higher scores indicate lower fatigue.	pre-intervention; bi-weekly during the intervention (up to 10 weeks); end of intervention (assessed up to 10 weeks); 12 weeks after the end of intervention; after intensive cancer treatment; 15 months after the end of intervention

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame

On the PedsQL Generic Core Scales, for ease of interpretability, items are reversed scored and linearly transformed to a 0-100 scale, so that higher scores indicate better HRQOL (Health-Related Quality of Life).	pre-intervention; bi-weekly during the intervention (up to 10 weeks); end of intervention (assessed up to 10 weeks); 12 weeks after the end of intervention; after intensive cancer treatment; 15 months after the end of intervention
Change in the score of cancer-related Health-Related Quality of Life during the intervention, after the intervention, and over a 1-year follow-up period compared with baseline	Health-Related Quality of Life measured by the Measurement Model for the Pediatric Quality of Life Inventory (PedsQL) 3.0 Cancer Module questionnaire. Scores are transformed to a 0 to 100 scale. Higher scores indicate lower problems.	pre-intervention; bi-weekly during the intervention (up to 10 weeks); end of intervention (assessed up to 10 weeks); 12 weeks after the end of intervention; after intensive cancer treatment; 15 months after the end of intervention
Change in the score of Mental Health (measured by WHO (Five) Well-Being Index) during the intervention, after the intervention, and over a 1-year follow-up period compared with baseline	WHO (Five) Well-Being Index (1998 version) is used to measure Mental Health.The WHO-5 consists of five statements, which respondents rate according to the scale below: All of the time = 5 Most of the time = 4 More than half of the time = 3 Less than half of the time = 2 Some of the time = 1 At no time = 0. The total raw score, ranging from 0 to 25, is multiplied by 4 to give the final score, with 0 representing the worst imaginable well-being and 100 representing the best imaginable well-being.	pre-intervention; bi-weekly during the intervention (up to 10 weeks); end of intervention (assessed up to 10 weeks); 12 weeks after the end of intervention; after intensive cancer treatment; 15 months after the end of intervention

WEMWBS is a 14 item scale of mental well-being covering subjective well-being and psychological functioning, in which all items are worded positively and address aspects of positive mental health. The total score of the 14-item scale WEMWBS is obtained by summing the score for each of the 14 items. The scoring range for each item is from 1 - 5 and the total score is from 14-70.	pre-intervention; bi-weekly during the intervention (up to 10 weeks); end of intervention (assessed up to 10 weeks); 12 weeks after the end of intervention; after intensive cancer treatment; 15 months after the end of intervention
Change in the score of Resilience (measured by Mainzer Resilience Scale for childhood cancer (MRScc)) during the intervention, after the intervention, and over a 1-year follow-up period compared with baseline	Stress reactivity measured by the Mainz Resilience Score for childhood cancer (MRScc). The MRScc consists of 4 dimensions on mental health problems and 6 dimensions on stressor exposure. For both categories mental health problems and stressor exposure 4 - 400 points can be achieved. To calculate the resilience score, the category mental health problems is divided by the category stressor exposure. A score >0 means low resilience, a score < 0 means high resilience.	pre-intervention; bi-weekly during the intervention (up to 10 weeks); end of intervention (assessed up to 10 weeks); 12 weeks after the end of intervention; after intensive cancer treatment; 15 months after the end of intervention

A higher score means a higher resilience.	pre-intervention; bi-weekly during the intervention (up to 10 weeks); end of intervention (assessed up to 10 weeks); 12 weeks after the end of intervention; after intensive cancer treatment; 15 months after the end of intervention

The items within the measures can be directly summed to gain a total score of an individual's resilience. For the unmodified 5-point measure (with responses going from 1-5), the minimum score is 17 and the maximum score is 85. For the overall measure and subscales, higher scores indicate characteristics associated with resilience.	pre-intervention; bi-weekly during the intervention (up to 10 weeks); end of intervention (assessed up to 10 weeks); 12 weeks after the end of intervention; after intensive cancer treatment; 15 months after the end of intervention
Change in the score of General self-efficacy during the intervention, after the intervention, and over a 1-year follow-up period compared with baseline	General self-efficacy will be evaluated using the General self-efficacy scale (GSE).
