1003 patients were analyzed. Learning difficulties at school were noted
in 22% of patients. A greater social deprivation was significantly
associated with learning difficulty (OR=1.09 per unit of the deprivation
score). Tumor relapse, treatment with hematopoietic stem cell
transplantation, and diagnosis of a CNS tumor remained significant risk
factors. In the subgroup analysis of children with CNS tumors, learning
difficulties were increased and associated with greater social
deprivation. By contrast, psychological difficulties were not associated
with the deprivation score.
