MRI FDG PET Imaging Cervix
The standard treatment for cervix cancer at Princess Margaret Hospital is external radiation with chemotherapy followed by internal radiation, called brachytherapy. Currently, brachytherapy treatment is planned on a type of Magnetic Resonance Imaging (MRI) called T2-weighted (T2W) MRI.
The main purpose of this study is to determine whether the following imaging tests can visualize the tumor better for planning the brachytherapy treatment:
- special types of MRI called diffusion weighted MRI (DWI) and dynamic-contrast enhanced MRI (DCE-MRI); and
- an x-ray test called positron emission test (PET) performed with a sugar dye called FDG. MRI-guided brachytherapy is resource-intensive and not widely available.
|Study Design:||Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
|Official Title:||A Pilot Prospective Study of the Utility of Dynamic Contrast-Enhanced Magnetic Resonance Imaging (DCE-MRI), Diffusion Weighted MRI (DWI)and Positron Emission Tomography (PET) Imaging With 18F-Fluorodeoxyglucose (18FDG) in Brachytherapy for Cervix Cancer|
- Target delineation in brachytherapy using standard T2-weighted MRI versus DCE-MRI, DWI and FDG-PET/CT imaging: gross tumor volume and high-risk clinical target volume in patients with cervical cancer [ Time Frame: 2 years ]
- Target delineation using standard MRI acquired during the last week of EBRT fused to planning CT versus full MRI-guided brachytherapy. [ Time Frame: 2 years ]This objective will evaluate the potential for translation of this technique to centres with limited MRI access.
- Follow-up imaging (MRI and 18FDG PET) versus the imaging done at the time of brachytherapy [ Time Frame: 2 years ]
- Imaging techniques for visualizing the brachytherapy applicator. [ Time Frame: 2 years ]
|Study Start Date:||October 2012|
|Estimated Study Completion Date:||October 2017|
|Primary Completion Date:||December 2016 (Final data collection date for primary outcome measure)|
|Experimental: 18-FDG PET/CT, DWI, DCE-MRI||
Biological: 18-FDG PET/CT, DWI, DCE-MRI
All patients on this study will receive a Diffuse Weighted MRI and Dynamic Contrast Enhancing MRI during the routine MRI session on the day of brachytherapy (additional 10 minutes), and a FDG PET/CT scanning session on the day of brachytherapy.
