    Abstract:
    OBJECTIVE: To determine whether prophylactic CNS chemotherapy for childhood acute lymphoblastic leukemia is associated with declines in neuropsychological abilities. METHODS: Growth curve analysis was used to examine neuropsychological outcome and treatment-related change in children (N = 30) who were treated at two childhood cancer centers. A comprehensive test battery was administered at baseline (8 months), 2, 3, and 4 years postdiagnosis (age at diagnosis M = 5.90 years, SD = 4.2C). RESULTS: Results indicated modest declines in arithmetic, visual motor integration, and verbal fluency. Intrathecal and systemic treatment was related to poorer visual motor integration at 4 years postdiagnosis and a faster rate of decline in visual motor integration skills across the observation period than intrathecal treatment alone. Arithmetic proficiency at 4 years after diagnosis was related to maternal education, but the rate of decline was not. Verbal fluency was unrelated to demographic or treatment variables. CONCLUSIONS: These findings suggest that neuropsychological outcome and declines are related to both demographic and treatment characteristics depending on the cognitive domain examined.
