• A Phase II Study of Hippocampal-Avoidance Using Proton Therapy in Low-Grade Glioma (HALGG) Rochester, Minn.

  The purpose of this study is to determine the feasibility of hippocampal-avoidance (HA) with proton therapy in suprasellar or midline low-grade gliomas (LGGs). 

• NRG-BN005, A Phase II Randomized Trial of Proton Vs. Photon Therapy (IMRT) for Cognitive Preservation in Patients With IDH Mutant, Low to Intermediate Grade Gliomas Rochester, Minn.

  This randomized phase II clinical trial studies the side effects and how well proton beam or intensity-modulated radiation therapy works in preserving brain function in patients with IDH mutant grade II or III glioma. Proton beam radiation therapy uses tiny charged particles to deliver radiation directly to the tumor and may cause less damage to normal tissue. Intensity-modulated or photon beam radiation therapy uses high-energy x-ray beams shaped to treat the tumor and may also cause less damage to normal tissue. Patients will be more likely to be randomized to proton beam radiation therapy. It is not yet known if proton beam radiation therapy is more effective than photon-based beam intensity-modulated radiation therapy in treating patients with glioma.

• Randomized Phase II Trial of Hypofractionated Dose-Escalated Photon IMRT or Proton Beam Therapy Versus Conventional Photon Irradiation With Concomitant and Adjuvant Temozolomide in Patients With Newly Diagnosed Glioblastoma Rochester, Minn., Scottsdale/Phoenix, Ariz.

  This randomized phase II trial studies how well dose-escalated photon intensity-modulated radiation therapy (IMRT) or proton beam radiation therapy works compared with standard-dose radiation therapy when given with temozolomide in patients with newly diagnosed glioblastoma. Radiation therapy uses high-energy x-rays and other types of radiation to kill tumor cells and shrink tumors. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Drugs, such as temozolomide, may make tumor cells more sensitive to radiation therapy. It is not yet known whether dose-escalated photon IMRT or proton beam radiation therapy is more effective than standard-dose radiation therapy with temozolomide in treating glioblastoma.

• Stereotactic Biopsy Split-Course Radiation Therapy - Diffuse Midline Glioma (SPORT-DMG) (GMROR2162) Rochester, Minn., Scottsdale/Phoenix, Ariz.

  The purpose of this study is to evaluate the clinical outcomes of hypofractionation with planned courses of re-irradiation for patients with diffuse midline gliomas of the pons.

  Subjects will be screened by neurosurgery, radiation oncology, or pediatric oncology at outpatient clinic or by the multidisciplinary pediatric central nervous system tumor conference. Interested qualified patients and their families will be consented and offered participation in this study
