There was no grade ≥3 toxicity, and no patient required a re-resection due to toxicity(20). Shepherd et al. reported hypofractionated stereotactic radiotherapy in treatment of ing tumor with a 1.5 cm margin. An isotropic expansion of 3 mm was added to the CTV 50 and CTV 60 to generate the planning target volume (PTV) 50 and PTV 60 respectively. A total dose of 60 Gy was delivered at 2 Gy per fraction (50 Gy in 25 fractions to CTV 50 followed by a boost of 10 Gy in 5 fractions to CTV 60) was delivered in the CRT arm. 59.4 Gy in 33 fractions over 6.5 weeks (Grade A) 60 Gy in 30 fractions over 6 weeks (Grade B) The types of evidence and the grading of recommendations used within this review are based on those proposed by the Oxford Centre for Evidence-based medicine.

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.

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.
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. 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
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). These results were confirmed by Chang et al.

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.

There was no grade ≥3 toxicity, and no patient required a re-resection due to toxicity(20).
Radiotherapy (50 Gy in 1.8‐Gy fractions over 5 weeks) had a proven OS benefit such as 34 Gy in 3.4‐Gy fractions or 25 Gy in 5‐Gy fractions, can also be& This is usually administered 5 days per week in doses of 1.8-2.0 Gy.
