In-Room PET in Proton Radiation Therapy

This study is currently recruiting participants. (see Contacts and Locations)
Verified December 2016 by Massachusetts General Hospital
National Cancer Institute (NCI)
Information provided by (Responsible Party):
Helen A. Shih, MD, Massachusetts General Hospital Identifier:
First received: October 25, 2010
Last updated: December 20, 2016
Last verified: December 2016
The investigational part of this study is using a mobile PET/CT scanner to take images of the participants tumor immediately after they are treated with proton radiation. This allows the participant to be treated and imaged on the same bed. The information obtained may improve the accuracy of treatment and may help to minimize the dose delivered unnecessarily to healthy tissue.

Condition Intervention Phase
Brain Tumor
Head and Neck Tumor
Skull Base Tumor
Procedure: PET scan
Early Phase 1

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic
Official Title: Pilot Study of In-Room PET in Proton Radiation Therapy

Further study details as provided by Massachusetts General Hospital:

Primary Outcome Measures:
  • Effectiveness [ Time Frame: 2 years ]
    Acquire PET/CT scan data in list-mode on patients undergoing external beam proton radiotherapy for brain and soft tissue tumors in head. Analyze these data to assess the effectiveness of using PET/CT for in-room PET monitoring for proton radiation therapy quality assurance.

Secondary Outcome Measures:
  • Optimize the in-room PET acquisition length [ Time Frame: 2 years ]
    Reconstruct these list-mode PET data for different scan durations and optimize in-room PET acquisition length

Estimated Enrollment: 39
Study Start Date: October 2010
Estimated Study Completion Date: June 2017
Estimated Primary Completion Date: June 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Participants 1-39
PET Scan done right after one radiation treatment is complete and will take 15-20 minutes. After undergoing their first PET scan, participants will have the option to undergo 1-2 additional scans throughout radiation treatment in the same manner as the first scan.
Procedure: PET scan
In-Room PET scan

Detailed Description:
For all participants, right after one regular treatment fraction, NeuroPET or NeuroPET II will be wheeled into the patient room. The patient bed will be moved directly into the scan position and a PET scan will be acquired in list-mode for 15 to 20 minutes followed by a CT scan for ~5 minutes. After undergoing their first PET scan, participants will have the option to undergo 1-2 additional scans throughout radiation treatment in the same manner as the first scan.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Adult subjects with brain, head and neck, and skull base tumors receiving external beam proton radiotherapy at the Francis H. Burr Proton Therapy Center at MGH
  • Age 18 or over
  • ECOG Performance status 0, 1 or 2

Exclusion Criteria:

  • Uncontrolled intercurrent illness that, in the opinion of the investigator, would limit the participant's compliance with study requirements.
