Objective: There is growing evidence of cerebellar-frontal system change in children treated for leukemia with chemotherapy alone (Lesnik et al., 1998). Methods: We compared 22 long-term survivors of acute lymphoblastic leukemia (ALL), aged 8-18, to 22 age- and gender-matched controls on tasks emphasizing cerebellar-frontal functioning including judgment of time duration and motor timing. Groups were also compared on a judgment of pitch task, used as a control measure. Children with ALL were at least 5 years from diagnosis, treated with intrathecal chemotherapy (methotrexate in all, hydrocortisone and cytarabine in 20/22), but not radiation therapy, and free from recurrence of disease. Results: After controlling for IQ, the ALL group had poorer performance than controls on judgment of long duration and motor timing, but not judgment of pitch. Conclusions: Treatment with intrathecal and infusional chemotherapy for childhood ALL may be associated with skill deficits comparable to those seen in individuals with cerebellar-frontal abnormalities.
