This is usually administered 5 days per week in doses of 1.8-2.0 Gy. Patients received 40, 45, and 50 Gy in 15 fractions to 95% of the planning target volume

2017-07-15 Better survival has been reported in elderly patients treated with RT compared with those receiving supportive care alone, with similar survival outcome for patients undergoing standard RT (60 Gy over 6 weeks) and hypofractionated RT (25⁻40 Gy in 5⁻15 daily fractions). 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.

The MS was 5.1 months in the SRT group and 5.6 months in the HRT group (p = 0.57) that established the non-inferiority of HRT compared to SRT in older patients with GBM. 17 The same group in a subsequent Phase III trial randomised 98 patients (frail = KPS 50 to 70 OR elderly = ≥65 years OR both) to two different HRT schedules of Arm 1 = 25 Gy/5F (1 week) or Arm 2 = 40 Gy/15 F (3 weeks). with glioblastoma. Based on evidence from the CE.6 randomized controlled trial, hypofractionated radiation therapy administered over a three-week course (40 Gy in 15 fractions) concomitantly with temozolomide (TMZ) followed by adjuvant TMZ has been found to be superior to radiation therapy alone with mean OS Currently, many approaches are available for the salvage treatment of patients with recurrent GBM, including resection, re-irradiation or systemic agents, but no standard of care exists.Methods: We analysed a cohort of patients with recurrent GBM treated with frame-less hypofractionated stereotactic radiation therapy with a total dose of 25 Gy in 5 fractions.Results: Of 91 consecutive patients fractions of 1.8 Gy per fraction or 60 Gy in 30 fractions of 2 Gy per fraction. Concurrent TMZ dosage was 75 mg/m2 given daily, 7 days per week, during radiation, whereas adjuvant TMZ was initiated at 150 mg/m2 on days 1 to 5 of 28-day cycles 1 month after radiation and escalated to 200 mg/m2, if toxicity was acceptable, for 5 to 11 addi- techniques (standard 2 Gy fraction, 2 Gy in ten 0.2 Gy fractions without gridblocking, two grid patterns, and a combination plan incorporating bothgrids) and analyzed with conformation numbers (CN), homogeneity indexes (HI),and dose volumes to normal tissues.
