Abstract

Between 1970 and 1985, 29 patients were postoperatively irradiated for medulloblastoma. Eight out of them received only a local irradiation and 21 a complete CNS irradiation. The posterior fossa was saturated up to a dose of 45 to 49 Gy in nine patients and 50 to 55 Gy in twelve patients. The patients treated by complete CNS irradiation show a three-year survival rate of 47% and a five-year survival rate of 40%. A nonsignificant increase of the three-year survival rate is found in patients whose posterior fossa was exposed to a higher radiation dose. Eleven recurrences were observed, and the posterior fossa was involved in seven out of these cases. Four recurrences confined to the spine were found after a dose of 20 to 30 Gy. Remote metastases, preferentially with a skeletal site, were formed in three out of 29 cases.
