Scientific title	Adjuvant postoperative high-dose radiotherapy for atypical and malignant meningioma: a phase II and observation study
Study objectives	This study is looking at how effective radiotherapy after surgery can be at preventing the reoccurance of meningioma, a type of brain tumour. The aims of this study are to see: 1. How long high dose radiotherapy stops the meningioma coming back for 2. How well people cope with the treatment 3. How well people having the treatment can carry out simple instructions and tasks afterwards
Ethics approval(s)	South East Research Ethics Committee, 05/09/2008, ref: 08/H1102/43
Health condition(s) or problem(s) studied	Topic: National Cancer Research Network; Subtopic: Brain Tumour; Disease: Brain and Nervous System
Intervention	Simpson grade 1 - 3: 60 Gy to the CTV1, treatment duration 6 weeks Simpson grade 4 - 5: 60 Gy to the CTV1 and then 10Gy boost to CTV2, treatment duration 7 weeks Follow up on both arms: 1st follow up 6 weeks post last irradiation, 2nd follow up will be 6 months after trial entry, 3rd follow up at 12 months and yearly thereafter.
Intervention type	Procedure/Surgery
Primary outcome measure(s)	1. Three year progression free survival (PFS) 2. Acute and long term toxicity Measured at baseline, during treatment, 6 weeks after end of radiotherapy (RT), 6 months after trial entry, 12 months after trial entry and then yearly. For both endpoints, the patients not having experienced the event(s) of interest are censored at the date of most recent follow-up.
Key secondary outcome measure(s)	Overall survival (OS), measured from date of entry to date of death, irrespective of the cause. For both endpoints, the patients not having experienced the event(s) of interest are censored at the date of most recent follow-up.
Completion date	28/02/2011

Key inclusion criteria	1. Histologically confirmed newly diagnosed meningioma, including the following subtypes (atypical World Health Organisation [WHO] grade II meningioma greater than or equal to 4 mitosis per high-power field [HPF] or the presence of at least 3 of the following variables): 1.1.
