Abstract

Abstract: Background: Acute lymphoblastic leukemia (ALL) is the most common cancer in children. Because of major improvements in treatment protocols, the survival rate now exceeds 80%. However, ALL treatments can cause long‐term neurocognitive sequelae, which negatively impact academic achievement and quality of life. Therefore, cognitive sequelae need to be carefully evaluated. The DIVERGT is a battery of tests proposed as a screening tool, sensitive to executive function impairments in children and adolescent cancer survivors. Our study aimed at verifying the predictive value of the DIVERGT on general cognitive functioning in adult long‐term survivors of ALL. Methods: ALL survivors completed the DIVERGT 13.4 years, on average, after remission (N = 247). In addition, 49 of these survivors (equally selected amongst those with low, average, and high DIVERGT scores) as well as 29 controls completed a more comprehensive neuropsychological evaluation within a 3‐year period from DIVERGT administration. Multivariate regression analysis was used to assess the predictive value of the DIVERGT on general intelligence, mathematics, verbal memory, and working memory. As a follow‐up analysis, three performance groups were created based on the DIVERGT results. Multivariate analysis of variance (MANOVA) assessed neuropsychological differences between groups. Results: The DIVERGT accurately predicted General Ability Index (GAI) ( P < 0.0001), mathematics ( P < 0.0001) and verbal memory ( P = 0.045). Moreover, the low‐performance group consistently had poorer performance than the high‐performance and control groups on the neuropsychological tests. Conclusion: The DIVERGT is a useful, time‐effective screening battery for broader neurocognitive impairments identification in long‐term adult ALL survivors. It could be implemented as routine examination in cancer follow‐up clinics.
