A Study to Evaluate Fractionated Radiation Therapy Utilizing GRID Therapy for Locally-advanced Bulky Tumors
Rochester, MN
The purpose of this research is to study radiographic control at the 3 month time-point, the side effects (good & bad), survival outcomes and proof of this idea in patients who have had grid therapy for locally advanced bulky tumors of the heat and neck, thorax, abdomen and extremities.

Conventionally Fractionated Vs. Hypofractionated
Comprehensive Nodal Irradiation For Breast Cancer Using Pencil Beam Scanning ProtonTherapy
Scottsdale/Phoenix, AZ
The purpose of this study is to determine if the 2-year rate of grade ≥3 treatment-related skin and soft tissue toxicities with comprehensive nodal irradiation for breast cancer using hypofractionated pencil beam scanning proton therapy (PBS-PT) is non-inferior to conventionally-fractionated PBS-PT.

A Study to Compare Single Fraction Stereotactic Radiosurgery Compared with Fractionated Stereotactic Radiosurgery in Treating Patients With Resected Metastatic Brain Disease
Jacksonville, FL; Rochester, MN; Scottsdale/Phoenix, AZ
The purpose of this study is to compare how well single fraction stereotactic radiosurgery works versus fractionated stereotactic radiosurgery in treating patients with cancer that has spread to the brain from other parts of the body and has been removed by surgery. Single fraction stereotactic radiosurgery is a specialized radiation therapy that delivers a single, high dose of radiation directly to the tumor and may cause less damage to normal tissue. Fractionated stereotactic radiosurgery delivers multiple, smaller doses of radiation therapy over time.
