[Medulloblastomas--the results after postoperative radiotherapy with and without adjuvant chemotherapy].
Between 1975 and 1991, 40 patients with newly diagnosed medulloblastoma were treated at the authors' institutions. After aggressive surgical resection 39/40 (98%) received craniospinal radiation therapy with a local boost to the posterior fossa and other macroscopically involved areas. A group of 29 patients was treated with adjuvant chemotherapy. The five-year actuarial survival and event-free survival were 75% and 65%, respectively. Survival was significantly better for patients treated after 1981 as compared to those treated between 1975 and 1980 (p = .02). Younger age (two to four years) was associated with a better prognosis (p = .02). The extend of resection, Chang-stage, radiation dose to posterior fossa and the use of chemotherapy did not significantly impact on survival and relapse-free survival.
