Title: Temozolomid (One Week on/One Week Off) Versus Strahlentherapie in Der Primärtherapie Anaplastischer Astrozytome Und Glioblastome Bei älteren Patienten: Eine Randomisierte Phase III-Studie (Methvsalem)
Brief Summary: The study aims to optimize the treatment of elderly subjects (\> 65) with anaplastic astrocytoma and glioblastoma. Current treatment policies tend to be no more than palliative. There is no consensus as to how radical the surgery should be. Involved-field radiotherapy is the treatment most likely to be accepted apart from supportive and palliative measures. The role of chemotherapy is barely defined. Study data available to date does not suggest that this patient population would benefit from combined radiochemotherapy. The aim of the study is to verify the hypothesis that first-line chemotherapy with one week on/one week off temozolomide is not inferior to extended-field radiotherapy in the first-line treatment of anaplastic astrocytoma and glioblastoma in the elderly (\> 65 age group). The primary endpoint is median survival, as life expectancy is limited to several months. Secondary endpoints are response rates in both arms (CR, PR, MacDonald et al. 1990), median progression-free survival, 1-year and 2-year survival rates, definition of MGMT as molecular genetic prognostic or predictive markers, and quality of life. Theoretically, it should be possible to preserve quality of life in the first-line chemotherapy arm of the study.
