Therapeutic advances in pediatric oncology have made it possible to increase the five-year survival rate of 80% for all types of cancer, giving the possibility of a growing number of children reaching adulthood. This increase in the survival rate is not without cost for the survivors. The most common complications are endocrinopathies and affect approximately 50% of children cured of cancer. Overall mortality increases significantly over time : 6,5% at 10 years (confidence interval [CI] at 95%, 6,2-6,9), 11,9% at 20 years (CI at 95%, 11,5-12,4), and 18,1% at 30 years (CI at 95%, 17,3-18,9). Premature mortality is essentially due to a recurrence of the initial cancer, while late mortality is attributable to the consequences of treatment. Compared to children cured of cancer, adolescents and young adults have a lower risk of death due to later exposure to cancer treatment : 4,8 (CI 95%, 4,4-5,1) against 6,8 (IC 95%, 6,2-7,4), respectively. The psychological and social impact of the experience of cancer and its treatment is in the middle of the discussion. It is strongly recommended that adults cured of cancer benefit from a personalized follow up, according to a global approach. This follow up should be interdisciplinary and should focus on the prevention and management of late effects through screening, education on treatment-related complications, and should encourage preventive lifestyle behaviors.
