Rates of below average (\u2264 25th percentile) scores in this sample were compared with test norms, and performances were compared across anatomic sites. Finally, the relationships of pre-, peri-, and postsurgical complications to outcome were investigated. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p> For the entire sample, there was a significantly elevated rate of below average scores across intelligence quotient, achievement, and adaptive behavior, but not behavioral\/emotional adjustment measures. Patients with hemispheric, midline, and brainstem tumors did not differ significantly. Patients with left hemisphere tumors generally performed worse than those with right hemisphere tumors. Finally, neurobehavioral outcome was unrelated to pre-, peri-, or postsurgery complications. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p> After surgery for low-grade brain tumors, a significant number of patients was found to function below average, by as much as 55% compared with 25% in the normative population. Moreover, these results suggest greater risk for patients with lesions situated in the left cerebral hemisphere. Routine neuropsychological follow-up of children after treatment for low-grade tumors is recommended. <\/jats:p><\/jats:sec>","DOI":"10.1200\/jco.2008.17.1371","type":"journal-article","created":{"date-parts":[[2008,9,9]],"date-time":"2008-09-09T00:55:14Z","timestamp":1220921714000},"page":"4765-4770","source":"Crossref","is-referenced-by-count":90,"title":["Cognitive and Adaptive Outcome in Extracerebellar Low-Grade Brain Tumors in Children: A Report From the Children's Oncology Group"],"prefix":"10.1200","volume":"26","author":[{"given":"M.
