  Purpose

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:

  1. special types of MRI called diffusion weighted MRI (DWI) and dynamic-contrast enhanced MRI (DCE-MRI); and
  2. 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.

Condition Intervention
Cervical Cancer Squamous Cell Biological: 18-FDG PET/CT, DWI, DCE-MRI

Study Type: Interventional
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

Primary Outcome Measures:
  • 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.


Secondary Outcome Measures:
  • 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 ]

Estimated Enrollment: 30
Study Start Date: October 2012
Estimated Study Completion Date: October 2017
Primary Completion Date: December 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
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.
