Physical Activity Adapted at Home Supervised by Videoconferencing in Post-cancer for Children / AYA Treated for Leukemia (ONCOPED SAPATIC)

Leukemia is the most common form of cancer (29%) in children, adolescents, and young adults (AYA). Current treatments for leukemia (conventional chemotherapy or hematopoietic stem cell transplantation) can lead to significant side effects, acute or chronic, which can lead to impaired physical abilities and reduced quality of life for patients in short, medium or long term. For children and AYA with cancer, adapted physical activity (APA) is now recommended even if the scientific evidence of its benefit is still insufficient. However, some publications show clearly the benefits of an APA program for this population. It is important to note that these studies (and therefore the evaluated APA programs) were carried out during hospitalization, where a significant sedentary situation was reported in children/AYA with cancer, especially on their return home. The main barriers to the practice of APA, recently described in the literature, are: 1 / Patient's distance from the health center (geographical and social inequality); 2 / Insufficient involvement of the family environment (social inequality); 3 / Social rupture of the child / AYA. To neutralize these particularly marked inequalities in post-cancer period, the introduction of a home-based APA program represents an innovative and relevant solution. Thus, it was reported that 91% (out of 1500 participants) of children / AYAs with cancer wish to engage in physical activity at home regardless the time of the care course. In addition, the use of new information and communication technologies (ICT) such as videoconferencing does not constitute a barrier to the practice of APA for this young population familiar with connected tools. The practice of APA could even be an important lever in the fight against sedentary lifestyle by inducing a long-term change in behavior. In order to achieve these objectives, the APA programs in children/AYA with cancer should meet 3 major criteria: 1 / Professionally supervised sessions; 2 / Progressive increase in number and intensity of sessions; 3 / Accompanying the patient to an independent practice of regular physical activity. To date, the studies reported in literature have proposed "APA follow-ups" at home only by mail, telephone or via internet applications. Their effects appear limited on physical capacities for children/AYAs with cancer. However, according to these authors, setting up a home-based APA program through the use of ICTs would maximize the benefits on the physical capabilities and quality of life of all these patients. To the investigator's knowledge, no study has yet been conducted to evaluate the feasibility of such a program, and its consequences on patients.
