Study information
Scientific title
Adjuvant postoperative high-dose radiotherapy for atypical and malignant meningioma: a phase II and observation study
Acronym
Study hypothesis
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

Primary outcome measure
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.
Secondary outcome measures
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.
