Three of 37 adolescents in long-term remission from childhood acute lymphoblastic leukemia (ALL) developed malignant multifocal gliomas several years after completing treatment that included central nervous system (CNS) prophylaxis with radiation (RT) and intrathecal methotrexate (IT-MTX). No recurrence of the leukemia was evident when the CNS tumors were discovered. Seventeen other similar cases have been recorded. The occurrence of second malignancies is reviewed in the context of this development and of the oncogenic effects of radiation. It is probable that prolonged exposure to IT-MTX may have had a synergistic effect with radiation in contributing to the unusual incidence of glial tumors in these patients.

Abstract
Three of 37 adolescents in long-term remission from childhood acute lymphoblastic leukemia (ALL) developed malignant multifocal gliomas several years after completing treatment that included central nervous system (CNS) prophylaxis with radiation (RT) and intrathecal methotrexate (IT-MTX). No recurrence of the leukemia was evident when the CNS tumors were discovered. Seventeen other similar cases have been recorded. The occurrence of second malignancies is reviewed in the context of this development and of the oncogenic effects of radiation. It is probable that prolonged exposure to IT-MTX may have had a synergistic effect with radiation in contributing to the unusual incidence of glial tumors in these patients.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
