Comparative study of the cognitive profile of school-age children who completed treatment for infratentorial and supratentorial brain tumors: Impact on school performane and health-related quality of life

Abstract

Introduction: Due to scientific advances, there is a growing number of pediatric patients surviving cancer. In general, for children who suffer from central nervous system tumors, this survival is associated with secondary adverse effects, such as cognitive deficits. Objetive: To assess cognitive functions and quality of life in children with infratentorial and supratentorial brain tumors. Methods: An analytical observational and prospective study was conducted. The total sample consisted of 51 subjects. The following measurement instruments were used: Wechsler Intelligence Scale for Children, Fourth Edition (WISC IV), Cognitive Assessment System (CAS), Test of Memory and Learning (TOMAL), Graffar Scale; and Peds Quality of Life 4.0 Results: The comparison of the results did not show significant differences between infratentorial and supratentorial tumor location. All patients that were evaluated in the post-cancer-treatment period reveled a similar significant impairment in all the areas studied compared with the level expected in the general population. The most severely affected cognitive functions were processing speed and attention span, mainly on the planning tasks. The findings also show that quality of life at school is severely affected in these children. Conclusions: This is a preliminary study whose results may define a general trend of neurocognitive status, analyzing its impact on quality of life of the study population an posing useful questions for future research.
