Early Tumor Treating Fields (TTFields, Optune®) treatment
Late TTF treatment
TTF will be started together with hypofractionated radiotherapy (+/- 5 days) with or without Temozolomide (according to the standard and local physician's decision). Chemoradiotherapy with temozolomide and hypofractionated radiotherapy is regarded as standard therapy and not part of the intervention. In case of chemoradiotherapy temozolomide will be applied according to the standard of the participating trial center. Use of antiemetic and infection prophylaxis will be at the discretion of the investigator.
