Hypoxia-PET and IMPT Dose Painting in Patients With Chordomas: A Pilot Study

Status: Completed
Location: See location...
Intervention Type: Procedure
Study Type: Interventional
Study Phase: Not Applicable

Before radiation treatment is given to treat chordomas, CT and MRI scans are used to create a three dimensional picture of the tumor using x-rays. The CT and MRI scans are used to determine the size and location of the area that will receive radiation treatment. The purpose of this research study is to see if combining the images from the FMISO-PET scan and the CT and MRI scans in radiation treatment planning changes the size and location of the area that will receive radiation treatment when compared to planning the radiation treatment with CT and MRI scans alone.

Target number of participants: 20
Experimental: (18F)-FMISO/CT
The study utilizes PET/CT scanning with (18F)-FMISO/CT in addition to standard used CT and MRI. Patients enrolled in this trial completed 2 PET/CT investigations, the first before proton radiation therapy and the second at a dose of approximately 30 Gy (24-36 Gy).
