Active Comparator: 25 Gy in 5 fractions Patients randomized to 25 Gy in 5 fractions will receive 150 mg/m^2 temozolomide per day for 5 days starting the first day of radiotherapy. This treatment will be followed by standard monthly 5 day cycles at 150 mg/m^2 for upto 1 year.

More recently, shorter regimens such as 25 Gy/5 fractions and 34 Gy/10 fractions have shown to be equally effective in elderly and/or frail patients. However, it has to be noted that the definition of elderly has varied among these trials from above 60 [ 14 ], 65 [ 15 ] and 70 years [ 16 ]. 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. In 2015, the International Atomic Energy Agency published results from a randomized phase 3 trial of RT in elderly or frail patients randomized to two regimens of hypofractionated RT: 40 Gy in 15 fractions over 3 weeks vs 25 Gy in 5 fractions over 1 week .

with 25 Gy in 5 fractions (23). The trial included newly diagnosed glioblastoma aged 65 years or older and patients aged 50 years or older with a Karnofsky performance score (KPS) of 50–70. With 98 patients enrolled, there were no reported differences in OS between the two groups: the 25 Gy cohort had a median OS of 7.9 months and the 40 Gy 2020-01-31 More recently, Roa et al.

Trials of radiotherapy alone in selected patients found that 40 Gy in 15 fractions had equivalent OS to 60 Gy in 30 fractions 3 and that 25 Gy in 5 fractions was non-inferior to 40 Gy in 15 fractions. 4 Furthermore, conventional 6 weeks of treatment was associated with worse survival compared with a hypofractionated regimen of 34 Gy in 10 fractions. 16 The addition of standard concurrent and adjuvant TMZ with 40 Gy in 15 fractions, compared with the same radiotherapy alone, improved OS A subsequent phase III trial showed noninferiority of 25 Gy in 5 fractions compared to the commonly used 40 Gy in 15 fractions regimen with median survivals of 7.9 vs 6.4 mo, respectively, and no difference in quality of life outcomes. 40 These data clearly support shortened radiation courses for elderly patients; however, hypofractionation as a method of escalating dose is not yet proven. Results Fourteen patients received SRS with a median dose of 25 Gy (range, 20-32 Gy) in 1-5 fractions.
