  1. aThe pre-operative tumour volume and the extent of resection were evaluated based on the contrast enhanced T1-weighted MRI.
  2. GTR = gross total resection; STR = subtotal resection; PFS (progression free survival); OS = overall survival; MGMT = O6-methylguanine DNA methyltransferase; IDH-1 = Isocitrate dehydrogenase.
