Parent-reported executive functioning in young children treated for cancer

ABSTRACT

It is well known that children treated for cancer are at risk for cognitive and functional impairments. Such research is largely based on studies of late effects in school-aged or older children. However, far less is known about executive function weaknesses in preschool-aged children treated for cancer. Thus, the aim of this study was to examine executive functioning in a clinically referred sample of young oncology patients, and its association with broader domains of functioning. Data from 61 young children with cancer, who were referred for clinical cognitive evaluations, were abstracted and included in this study. Patients were 5.00 years of age (SD = 0.72) at assessment, 54.1% male, and two-thirds (63.9%) had been treated for brain tumors. Most executive functions were significantly discrepant from the mean, with 47.5% of preschoolers having parent-reported working memory concerns within the clinically significant range. There were no differences in executive functioning based on diagnosis or treatment status. Parent-reported executive functioning was strongly correlated with global intelligence and adaptive functioning, with some indices also associated with nonverbal problem solving and pre-academic skills. Ultimately, results indicate the presence of emerging weaknesses in executive functioning in young children with cancer, and add to a growing body of literature highlighting the potential cognitive and behavioral risks associated with a cancer diagnosis in early childhood.
