1. Change from baseline in cancer-related fatigue score at yearly intervals up to 5 years (Time Frame - baseline, after 1 year, after 2 years, after 3 years, after 4 years, after 5 years): 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.
Secondary outcome:
1. Change from baseline in the score of resilience (measured by Mainzer Resilience Scale for childhood cancer (MRScc)) at yearly intervals up to 5 years (Time Frame - baseline, after 1 year, after 2 years, after 3 years, after 4 years, after 5 years): 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.
2. Change from baseline in the score of resilience (measured by the Brief Resilience Scale (BRS)) at yearly intervals up to 5 years (Time Frame - baseline, after 1 year, after 2 years, after 3 years, after 4 years, after 5 years): Resilience will be evaluated using the Brief Resilience Scale (BRS). BRS is a 6 item scale, the items are rated from 1 to 5. A total score is calculated by determining the sum of the individual items which result in a total score ranging from 6 to 30. A higher score means a higher resilience.
3. Change from baseline in the score of resilience (measured by the Child & Youth Resilience Measure-Revised (CYRM-R)) at yearly intervals up to 5 years (Time Frame - baseline, after 1 year, after 2 years, after 3 years, after 4 years, after 5 years): Resilience will be evaluated using the Child & Youth Resilience Measure-Revised (CYRM-R).
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.
4. Change from baseline in general self-efficacy score at yearly intervals up to 5 years (Time Frame - baseline, after 1 year, after 2 years, after 3 years, after 4 years, after 5 years): General self-efficacy will be evaluated using the General self-efficacy scale (GSE).

5. Change from baseline in the score of physical exercise self-efficacy at yearly intervals up to 5 years (Time Frame - baseline, after 1 year, after 2 years, after 3 years, after 4 years, after 5 years): Physical self-efficacy will be evaluated using the Physical exercise self-efficacy scale (PESE). The total score is calculated by finding the sum of the 10 items. For the GSE, the total score ranges between 5 and 20, with a higher score indicating more self-efficacy.
6. Change from baseline in the risk status of pain-related outcomes at yearly intervals up to 5 years (Time Frame - baseline, after 1 year, after 2 years, after 3 years, after 4 years, after 5 years): Risk will be evaluated using the Pediatric Pain Screen Tool (PPST). The questionnaire consists of nine items intended to identify a patient's risk status (high, medium, or low) of poor pain-related outcome using established psychosocial prognostic factors. The PPST is adapted from the Keele STarT Back Screening Tool (SBST) and validated for the pediatric population from 8 to 18 years. The PPST contains two subscales: physical and psychosocial items. Summing all items, PPST total scores range from 0 to 9. Psychosocial subscale scores range from 0 to 5 and 0 to 4 for the physical subscale. The low risk group was defined as a PPST total score of 0 to 2 (PPST total cutoff for disability minus the PPST psychosocial subscale cutoff for psychosocial distress). For the high-risk group, a score of 3 or greater for the PPST psychosocial subscale was defined as high-risk, and last, a total PPST score greater than or equal to 3 and psychosocial subscale 0 to 2 were defined as medium risk.
7. Change from baseline in the subjective pain perception (measured with the face pain scale - revised (FPS-R)) at yearly intervals up to 5 years (Time Frame - baseline, after 1 year, after 2 years, after 3 years, after 4 years, after 5 years): The subjective pain rating will be measured using the Face Pain Scale - Revised (FPS-R), that is a self-report measure of the actual, subjective pain intensity developed for children. The FPS-R was adapted from the Faces Pain Scale to make it possible to score the sensation of pain on the 0-to-10 metric in children and adolescents. The scale shows a close linear relationship with visual analog pain scales across the age range of 4-16 years and has already been used and validated with children and adolescents. In addition, a visual analog scale (0-10, VAS) is used to assess the current perception of pain in study participants aged 8 years and older.
8. Change from baseline in the subjective pain perception (measured via visual analog scale (VAS)) at yearly intervals up to 5 years (Time Frame - baseline, after 1 year, after 2 years, after 3 years, after 4 years, after 5 years): In addition to the face pain scale - revised (FPS-R), a visual analog scale (0-10, VAS) is used to assess the current perception of pain in study participants aged 8 years and older.

The questionnaire intended to assess a parent's pain-related fears and avoidance behaviour. The total scale score reflects parents' own pain-related fear and avoidance in the context of their child's pain, and the four subscale scores reflect: Avoidance, Fear of Pain, Fear of School, and Fear of Movement. Higher scores indicate higher levels of fear. The PFOPQ will be used since Fear and avoidance have been consistently associated with poor pain-related outcomes in children.
10. Change from baseline in the score of pain vigilance and awareness at yearly intervals up to 5 years (Time Frame - baseline, after 1 year, after 2 years, after 3 years, after 4 years, after 5 years): Pain Vigilance and Awareness will be measured using the Pain Vigilance and Awareness Questionnaire - Child version (PVAQ-C) that consists of 14 items to assess multidimensional aspects of attention to pain sensations in children. Items are rated on a six-point scale, ranging from 0 (never) to 5 (always). Items are summed to create a total score. Attention to pain is thought to be a key mechanism influencing the experience and chronification of pain. Sustained attention to pain is thought to lead to poor outcomes in both adults and children with chronic pain.
