Neuropsychological Outcomes From a Randomized Trial of Triple Intrathecal Chemotherapy Compared With 18 Gy Cranial Radiation As CNS Treatment in Acute Lymphoblastic Leukemia: Findings From Dana-Farber Cancer Institute ALL Consortium Protocol 95-01

Abstract

This randomized trial revealed only subtle differences 6 years after diagnosis between children who received CNS therapy as CRT plus double IT drug or as intensive triple IT drug. In most situations where comparable therapeutic efficacy can be achieved without CRT, it is preferable to do so. Where therapeutically necessary, however, CRT at lower doses may not add risk for significant neurotoxicity.
