Hypoxia-positron Emission Tomography (PET) and Intensity Modulated Proton Therapy (IMPT) Dose Painting in Patients With Chordomas

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.

Further study details as provided by Massachusetts General Hospital:

Primary Outcome Measures:
  • To evaluate if FMISO-PET is a feasible approach for the visualization of hypoxia in skull base and spinal CD. [ Time Frame: 2 years ]

Secondary Outcome Measures:
  • To investigate if using a Dose Painting/IMPT approach based on FMISO-PET/CT/MRI the irradiation dose can be escalated and the normal tissue be better spared in comparison to a IMPT approach based on anatomical imaging alone. [ Time Frame: 2 years ]
  • To evaluate and improve the precision of patients' positioning and image fusin using PET/CT for radiation treatment planning. [ Time Frame: 2 years ]

Enrollment: 20

Primary Completion Date: June 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
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).
Procedure: Fluoromisonidazole-PET/CT
2 scans at different time intervals: 2 weeks before and 3 weeks after the participants first proton radiation treatment.
Other Name: FMISO-PET/CT

Detailed Description:
  • In this research study we are determining whether the positron emission tomography (PET) investigation performed with the investigational radioactive substance FMISO can show areas of tumor with lower oxygen levels. There is evidence that tumor with low oxygen levels are more resistant to radiation therapy. CT and MRI scans are not able to detect these oxygen levels in tumors.
  • Participants will be asked to have the FMISO-PET/CT scan at 2 different times. It will be performed 2 weeks before and 3 weeks after the participants first proton radiation treatment.
