A phase III trial conducted by Roa and colleagues compared two different hypofractionation schemes (40 G y in 15 fractions and 25 Gy in 5 fractions) without concurrent TMZ in patients ≥ 65 years of age with KPS >50 . No differences in OS, PFS, or quality of life were observed between the two arms.

Glioblastoma (GBM) is the most common primary brain tumor in adults and often occurs in patients over 65 years of age ().Historically, the treatment for GBM had consisted of maximal safe resection followed by an adjuvant nitrosurea, with trials by the Brain Tumor Study Group demonstrating evidence for post-op RT over best supportive care (2, 3). (60 Gy over 6 weeks) and hypofractionated RT (25–40 Gy in 5–15 daily fractions). Temozolomide, an alkylating agent, may represent an effective and safe therapy in patients with promoter methylation of O6-methylguanine-DNA-methyltransferase (MGMT) gene which … 50 Gy to PTV1 10 Gy to PTV2 25 fractions to PTV1 5 fractions to PTV2 Central/infield 80.9% Marginal 5.7% Distant 13.3% Median survival 14.2 mo Median time to recurrence 7.5 mo 1-y OS 66% 1-y PFS 30% Chang12 Retrospective 48 3D-CRT PTV1 = T1+2.5 cm PTV2 = T1+0.5 cm 50 Gy to PTV1 10 Gy to PTV2 25 fractions to PTV1 5 fractions to PTV2 Central population to a mean dose of 2.2 Gy over 30 fractions (0.5 Gy is lymphotoxic) – Marked reduction in treated volume was the only factor associated with lowering the lymphocytopenic dose • Protons with steep dose gradients and almost no exit dose represent a unique modality to reduce treated volume. Grossman, S. A., X. Ye, et al. (2011). 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.

Even shorter fractionation schedules, such as 34 Gy in 3.4‐Gy fractions or 25 Gy in 5‐Gy fractions, can also be considered, especially in extremely frail patients. 63 It should be noted, however, that those trials did not contain control arms with standard, long‐course, concurrent chemoradiation.

Survival analysis showed that More recently, Roa et al. investigated short-course radiation therapy (40 Gy in 15 fractions) compared to ultra-hypofractionated radiation therapy (25 Gy in 5 fractions) in elderly/frail patients with glioblastoma. 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.
