During the treatment period, (five-six weeks), most of the metastasize; this low number might be due to the fact that glioblastoma is a safe, followed by fractionated RT (typically 60 Gy in 30-35 fractions),. 3 Abstract Purpose: Improvements in mortality rate of glioblastoma patients have RT is delivered over the course of six weeks as Gy divided over fractions [2].

The first randomized trial to show a survival benefit with adjuvant radiation therapy (RT) was the Brain Tumor Study Group trial published in 1978, which showed a median survival of 37.5 weeks for RT alone, 25 weeks for adjuvant carmustine [1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU)] chemotherapy alone, and 17 weeks for supportive care without adjuvant treatment; combination of RT plus (+) BCNU yielded a survival of 40.5 weeks. An additional 5 mm was used for the PTV. This was treated to a dose of 50 Gy in 25 fractions and an additional 10 Gy in 5 fraction boost was delivered to the above defined GTV with a 0.5 cm PTV margin. A planning study by Chang et al. 59 was conducted in 48 patients comparing this approach with that of the RTOG 97‐10 trial.

Roa et al. reported no significant survival differences between 40 Gy in 15 fractions and 25 Gy in 5 fractions in the elderly or frail patients with GBM, suggesting that the α/β ratio of GBM could be lower than 2–3 Gy . The low α/β ratio of GBM supports the advantage of the hypofractionated approach and further studies are needed to develop the optimal dose-fractionation schedule, which meets efficacy and safety. Gy in 3 Gy fractions, 79% responded to 30 Gy in 3 Gy or 35 Gy in 3.5 Gy fractions. There was no grade ≥3 toxicity, and no patient required a re-resection due to toxicity(20). Shepherd et al.
