====== Glioblastoma Radiotherapy ======
Historically, the treatment for [[glioblastoma]] had consisted of [[maximal safe resection]] followed by an adjuvant [[nitrosourea]], with trials by the Brain Tumor Study Group demonstrating evidence for post-op [[Radiotherapy]] over best [[supportive care]]
((Walker MD, Green SB, Byar DP, Alexander E, Jr, Batzdorf U, Brooks WH, et al. Randomized comparisons of radiotherapy and nitrosoureas for the treatment of malignant glioma after surgery. N Engl J Med (1980) 303:1323–9.10.1056/NEJM198012043032303))
((Walker MD, Alexander E, Jr, Hunt WE, MacCarty CS, Mahaley MS, Jr, Mealey J, Jr, et al. Evaluation of BCNU and/or radiotherapy in the treatment of anaplastic gliomas. A cooperative clinical trial. J Neurosurg (1978) 49:333–43.10.3171/jns.1978.49.3.0333)).

Further analysis of the relationship between survival and [[radiation]] dose revealed a dose–effect relationship, with doses of 60 Gy providing superior [[survival]] when compared to lower doses
