IMpact of Mind-body Therapies (HYpnosis and Relaxation) on Anxiety in Children, Adolescents and Young Adults Who Had Been Treated in ONcology. Multicenter Study.

In France today, it is estimated that one in 850 people aged between 20 and 45 has been cured of cancer in childhood. Some descriptive studies have established that cancer diagnosis and treatment can affect psychological health, with an increased risk of depression, post-traumatic stress, anxiety and suicidal risk. A French study published by our team in 2015 and 2020 also showed that, as adults, 40% of former pediatric cancer patients experienced symptoms of anxiety, a rate significantly higher than that of the general French population (25%). While it is well established that it is essential to detect the onset of anxiety-depressive disorders and, if necessary, to set up conventional psychological treatment (CPT), few studies have sought to show the benefit of complementing this conventional CPT with mind-body therapies (MBT) in the post-cancer pediatric setting. This project aims to determine the benefit of mind-body therapies (hypnosis and relaxation) as a complement to conventional psychological treatment (CPT) in the management of anxiety in children, adolescents and young adults in remission from pediatric cancer or leukemia.
