The radiation therapy results of 56 cases of medulloblastoma

Fifty six patients with medulloblastoma who has been treated at the University of Minnesoa since 1942 were retrospectively evaluated. Patients who received irradiation to the entire central nerve system has better survival rates than those receiving limited irradiation. A control rate of 70% and been obtained in 15 patients who treated with 5000 rads/7-8 week to the whole brain and 3600 rads to the spinal cord. There was a 505 incidence of cauda equina syndrome in 14 patients who received supplemental intrathecal Au-198. Reirradiation of intracranial recurrence gives good symptomatic palliation and may occasinally yield a long-term survivors.
