Introduction. 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).

The treatment was delivered in 25 fractions with the dose to PTV1 escalated in three dose levels (60 Gy, 62.5 Gy, 65 Gy) while maintaining the dose for PTV2 constant at 45 Gy. The study reported no DLT and the pattern of recurrence was predominantly central, with only two patients relapsing outside the PTV1 and one patient developing marginal

These data compare favor- A short-course RT regimen of 25 Gy in 5 fractions is an acceptable treatment option for patients aged ≥65 years, mainly those with a poor performance status or contraindication to chemotherapy, which would be indicated in cases of methylated O6 methylguanine-DNA-methyltransferase promoter tumors. 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. 2017-07-15 · Following this tendency, the IAEA proposed a randomized trial comparing 25 Gy in 5 fractions over a period of 1 week versus 40 Gy in 15 fractions over a period of 3 weeks . The trial was designed to evaluate noninferior survival outcomes between the 2 arms.

2020-11-09 2019-06-06 2019-11-12 The treatment was delivered in 25 fractions with the dose to PTV1 escalated in three dose levels (60 Gy, 62.5 Gy, 65 Gy) while maintaining the dose for PTV2 constant at 45 Gy. The study reported no DLT and the pattern of recurrence was predominantly central, with only two patients relapsing outside the PTV1 and one patient developing marginal recurrence. 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 ]. 50.4–54 Gy in 28–30 fractions over 5.5–6 weeks (Grade C) 50–55 Gy in 30–33 fractions over 6–6.5 weeks (Grade C) Grade 2: 54–60 Gy in 30 fractions over 6 weeks (Grade D) Grade 3: 60 Gy in 30 fractions over 6 weeks (Grade D) The types of evidence and the grading of recommendations used within this review are based on In a subsequent prospective randomized trial by the same group, an even more hypofractionated course of RT (25 Gy in 5 fractions) was compared with 40 Gy in 15 fractions.

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).

Results Fourteen patients received SRS with a median dose of 25 Gy (range, 20-32 Gy) in 1-5 fractions. Twenty-two patients received HSRT with a median dose of 40 Gy (range, 31.5-52 Gy) in 6-20 fractions. There were six treatment-related grade 3 adverse events. Survival analysis showed that

DiscussionIn a previous report we showed that accelerated SIB IMRT to a dose of 65 Gy in 25 fractions (BED for glioblastoma = 83.0 Gy, and EQD2 for normal brain = 72.9 Gy) was well tolerated with concurrent and sequential TMZ at standard dose [27].
