The investigators will study the effects of an supevised exercise intervention along the duration of intensive treatment (neoadjuvant [solid tumours]/intense chemotherapy [leukemias], expected median duration 5-6 months) on several health-related variables. Participants will be recruited from 4 hospitals in Madrid (Spain). Inclusion criteria: male/female aged 12-19 years, newly diagnosed--or relapse of-- a malignant extracranial tumour; not having received any type of therapy--except surgery--at the time of diagnosis; adequate health status (Karnofsky/Eastern Cooperative Oncology Group scale score ≥50/≤2); to understand Spanish language and to provide written informed consent. The investigators will recruit ≥136 participants and conduct a randomised controlled trial. The intervention group will follow a supervised concurrent exercise program from the start to the end of intensive treatment. The exercise intervention will be performed in the hospital gymnasium or in the patients' ward (during neutropenic phases), and will also include supervised online sessions. Additionally, the intervention group will perform include inspiratory muscle training. The following outcomes will be assessed at baseline (diagnosis), end of treatment, and at 3-month follow-up in all participants: echocardiography-determined left ventricular function (primary outcome); and other echocardiography-determined variables, cardiac biomarkers, blood pressure, blood lipids, body composition, physical activity levels, energy intake, cardiorespiratory fitness, muscle strength, functional mobility, health-related quality of life, cancer-related fatigue, clinical variables, and potential biological underpinnings of exercise multisystemic benefits (metabolic and inflammatory markers, plasma proteome, gut microbiome, and immune function).
Background. Health promotion interventions are needed during adolescent cancer treatment to facilitate the acquisition of good health practices as patients transition to survivorship. Although meta-analytical evidence supports the health benefits of exercise in the context of childhood cancer, there is scant data focusing solely on adolescents.
Hypothesis and objectives. The investigators hypothesise that a supervised exercise intervention combined with lifestyle counselling during treatment for adolescent cancer will provide several health benefits, particularly related to the cardiometabolic profile. Thus, the investigators will study the effects of a supervised exercise intervention along the duration of intensive treatment (neoadjuvant [solid tumours]/intense chemotherapy [leukaemias], expected median duration 5-6 months) on several health-related variables.
Setting and Methods. Participants will be recruited from 4 hospitals in Madrid (Spain). Inclusion criteria: male/female aged 12-19 years, newly diagnosed with (or having relapse of) a malignant extracranial tumour; not having received any type of therapy--except surgery--at the time of diagnosis; adequate health status (Karnofsky/Eastern Cooperative Oncology Group scale score ≥50/≤2); to understand Spanish language and to provide written informed consent. The investigators will recruit ≥136 participants and conduct a randomised controlled trial (1:1 ratio randomisation with a block on gender and tumour type [leukaemias/lymphomas]). In addition to usual care, the two groups will receive health counselling twice a month (i.e., psychological intervention based on motivational interviewing techniques, as well as guidance on heathy activity, sleeping, and dietary habits). The intervention group will follow a physical exercise and lifestyle counselling program. The exercise intervention will be performed in the hospital gymnasium (3 sessions/week of aerobic and resistance exercises), except for neutropenic phases--during which time sessions will be performed in the patients' ward--and will also include online sessions. Inspiratory muscle training (5 days/week) will be also performed. Patients in the control group will have the option to go to the hospital gymnasium twice a month (to perform playing activities) in order to maximize compliance to the study and to maintain contact with them. The following outcomes will be assessed at baseline (diagnosis), end of treatment, and at 3-month follow-up in all participants: echocardiography-determined left ventricular function (primary outcome); and other echocardiographic variables, cardiometabolic biomarkers, blood pressure, blood lipids, dual-energy X-ray absorptiometry-determined body composition (fat [including visceral adipose tissue]/lean mass, bone mineral content/density), energy intake, cardiorespiratory fitness, muscle strength, functional mobility, health-related quality of life, cancer-related fatigue, clinical variables (survival, treatment tolerability, hospitalisation length), and potential biological underpinnings of exercise multisystemic benefits (cardiometabolic and inflammatory biomarkers, gut microbiome, and immune function [lymphocyte subpopulations, natural killer cell cytotoxicity]) (secondary outcomes).

Assessment staff will be blinded to participant randomisation assignment. Yet, because of the nature of the study, it will not be possible to conceal the group assignment from the staff (i.e., fitness specialists) involved in the intervention (physical exercise) sessions. Participants will be explicitly informed on the group to which they will be assigned as well as on the study hypotheses and will be reminded not to discuss their randomisation assignments with assessment staff and/or other patient.
