[Secondary cancers: Incidence, risk factors and recommendations].

Cure rates for most childhood cancers and adolescents have made remarkable progress over the last thirty to forty years. The development of secondary malignancies has become an important question for these patients. The frequency is low, but the risk is significantly higher (between 3 and 10 times) and it is the leading cause of long-term mortality off relapse. In this literature review, we discuss the epidemiological aspect and the risk factors contributing to this increased risk, and conclude with a summary of current recommendations for screening and surveillance. We also discuss briefly the constitutional predisposing genetic contributions to other cancers.
