Rochester, Minn.
The purpose of this study is to compare clinical features and outcomes for children and adults with Ewing Sarcoma at the same institution and add to the limited clinical literature on adults with Ewing Sarcoma.

MC1973: A Phase II Study of Hypofractionated Pre-Operative Radiation Therapy for Localized, Resectable Soft Tissue Sarcoma of the Extremity or Superficial Trunk
Rochester, Minn.,
Jacksonville, Fla.,
Scottsdale/Phoenix, Ariz.
We propose conducting a single arm, prospective study to evaluate the efficacy and safety of a preoperative hypofractionated course, 42.75 Gy in 15 fractions, for localized, extremity and superficial trunk soft tissue sarcomas. The biologic equivalent dose of this regimen is 45.20 Gy10, similar to 43.83 Gy10 associated with conventionally fractionated 50 Gy in 25 fractions, to determine acute wound complications rates, analyze local failure rate, disease-free survival, overall survival, patterns of relapse, late toxicities, quality of life/patient-reported outcomes, and cost differences. We hypothesize a 15 fraction hypofractionated radiation therapy course will be associated with equivalent short term toxicity rates and oncologic outcomes, as compared to historical standards.

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
