Brief Summary

This phase II trial studies how well temozolomide and radiation therapy work in treating patients with IDH wildtype historically lower grade gliomas or non-histological molecular glioblastomas. Radiation therapy uses high-energy x-rays to kill tumor cells and shrink tumors. Giving chemotherapy with radiation therapy may kill more tumor cells. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. The goal of this clinical research study is to compare receiving new radiation therapy doses and volumes to the prior standard treatment for patients with historically grade II or grade III IDH wild-type gliomas, which may now be referred to as IDH wildtype molecular glioblastomas at some institutions. Receiving temozolomide in combination with radiation therapy may also help to control the disease.

Outcome Measures

Primary Outcomes (1)

  • Progression free survival (PFS)

    Tumor progression is defined by the Response Assessment in Neuro-Oncology glioma criteria. PFS time will be estimated using the Kaplan-Meier method. The 1-year PFS rate will be estimated along with a 95% confidence interval. Patient or tumor characteristics (ex. grade, age, etc) will be compared within the single study cohort. Cox regression models will be applied to assess the effect of covariates of interest on PFS.

    From start of treatment until objective tumor progression or death, whichever happens first, assessed up to 52 months

Secondary Outcomes (1)

  • Overall survival (OS) rate

    From start of treatment until death from any cause, assessed at 3 years

Other Outcomes (4)

  • Local control patterns (site of 1st progression)

    Up to 3 years

  • Neuro-cognitive function

    Up to 3 years

  • Symptom burden

    Up to 3 years

  • +1 more other outcomes

Study Arms (1)

Treatment (temozolomide, radiation therapy)

EXPERIMENTAL

Patients receive temozolomide PO daily and radiation therapy over 5 days a week (weekdays only) for 6 weeks. Beginning 28 days after the last dose of radiation therapy, patients receive temozolomide PO for 12 months in the absence of disease progression or unacceptable toxicity.
