Brief Summary
This research study is studying a new schedule of radiation therapy for recurrent glioblastoma as a possible treatment for this diagnosis. This radiation schedule is based on a new model for radiation resistance in glioblastoma. The name of the radiation schedule involved in this study is: \- Re-irradiation for glioblastoma using a novel Mathematical Model-Adapted Radiation Fractionation Schedule

Outcome Measures
Primary Outcomes (1)
Number of Participants to Complete Model Adapted Radiations Fractionation Scheduled
Successful completion of radiotherapy is defined as receipt of all scheduled fractions of daily radiotherapy within 24 hours of once daily fractions and within 1 hour of three-times daily fractions.
10 Days
Secondary Outcomes (8)
Number of Participants With Radiation Necrosis
6 months
Number of Participants With Seizures
6 months
Overall Survival (OS)
range of follow-up from date of registration was 1.2 - 38.6 months
Grade 3-5 Treatment-related Toxicity Rate
6 Months
Median Progression-Free Survival (PFS)
Disease evaluated on visit 4,5,6 and every 2-4 months in long-term. The range of follow-up from date of registration was 1.2 - 38.6 months and the median was 7.3 months.
- +3 more secondary outcomes

EXPERIMENTALMathematical Model-Adapted Radiation Fractionation Schedule
Interventions
* Re-irradiation with 35 Gy delivered over 2 weeks, based upon reference dosing of 35 Gy in 10 Fractions over 2 weeks * Radiation therapy is delivered on Monday-Friday during standard clinic hours in our department. Each treatment may take 20-40 minutes. * Treatment will be once daily for the first 7 days of treatment and then three-times daily for the last three days of treatment.
Eligibility Criteria
You may qualify if:
- Participants must have recurrent glioblastoma (WHO Grade IV), as defined on brain imaging with CT or MRI, after prior receipt of definitive therapy including neurosurgical biopsy or resection and radiation therapy with or without systemic therapy.
- Participants must be deemed appropriate candidates for re-irradiation
- Histopathologic confirmation of disease as part of routine clinical care is required either at the time of initial diagnosis and/or at the time of recurrent disease. There is no requirement for central pathologic review.
- Age ≥ 18 years at the time of enrollment
- Karnofsky Performance Status (KPS) of at least 70
You may not qualify if:
- Participants who have received more than one prior course of radiotherapy to the local site of progressive disease
- Participants who have received prior radiotherapy to the local site of progressive disease within \< 3 months of the anticipated start of re-irradiation
- Participants with recurrent tumor extensively abutting or involving the optic structures or brainstem, as assessed by the treating radiation oncologist
- Participants without a definable tumor cavity on MRI or CT obtained at study enrollment
- Participants receiving concurrent cytotoxic chemotherapy (i.e. temozolomide, CCNU, vincristine, procarbazine) or concurrent immunotherapy (i.e. pembrolizumab, nivolumab); however, participants may receive sequential chemotherapy before or after radiation without limitation. Participants may receive concurrent corticosteroid and/or anti-angiogenic therapy (i.e. bevacizumab) if clinically indicated.

Limitations and Caveats
Quality of life assessment using MDASI-BT was incomplete due to patient preference and incomplete adherence. As such, assessment by this endpoint was not possible.
