Thirteen patients with medulloblastoma were admitted to the Clinica Puerta de Hierro (Department of Radiotherapy) between 1964 and 1977. Two subtypes of medulloblastoma (classical and desmoplastic) with different histologic pattern, age of onset, clinical manifestations and clinical course have been identified. Radical surgery does not increase overal survival. X-ray treatment should be applied according to the following principles: a) the central nervous system should be irradiated; b) dosage on the posterior cranial fossa over 5,000 rad (50 Gy); c) dosage on the neuroaxis under 2,000-3,000 rad (25-30 Gy). Tumor recurrences should be treated in order to obtain a more comfortable life and a prolonged survival. Association of chemotherapy to surgery and radiotherapy have yielded promising results.
