Title: Effects of central-nervous-system irradiation on neuropsychologic functioning of children with acute lymphocytic leukemia. Author: Soni SS, Marten GW, Pitner SE, Duenas DA, Powazek M. Journal: N Engl J Med; 1975 Jul 17; 293(3):113-8. PubMed ID: 1055858. Abstract: Two neuropsychologic studies were performed to determine the long-term effects of "prophylactic" cranial or craniospinal irradiation on the psychologic and neurologic functions of children with acute lymphocytic leukemia. In a prospective study, 34 patients with leukemia who received either craniospinal irradiation or cranial irradiation combined with intrathecal methotrexate were evaluated by standardized neurologic and psychologic examinations before and after irradiation. Their performance was compared with that of 27 controls who received irradiation to parts of the body other than the cranium. In a retrospective study, 11 patients with leukemia receiving prophylactic craniospinal irradiation and 12 controls with the disease not receiving such therapy were followed from the second year after either irradiation or the initial hematologic remission. Eighteen months after irradiation in the prospective study and four years after irradiation in the retrospective study, no noteworthy neurologic or psychologic differences were found between subjects and controls.[Abstract] [Full Text] [Related] [New Search]
