The purpose of this study is to test whether or not a new contrast agent called Combidex, a contrast agent formulated from ultra-small superparamagnetic iron oxide (USPIO) improves the ability of Magnetic Resonance Imaging (MRI) to see lymph nodes in the pelvis. It might also help doctors tell whether or not cancer has spread to these lymph nodes. It might allow radiotherapy to be delivered more accurately.

Further study details as provided by University Health Network, Toronto:

Primary Outcome Measures:
  • Improved delineation of normal pelvic lymph nodes in patients with uterine, cervical, bladder and prostate cancers. [ Time Frame: once at time of imaging ]
  • Improved clinical target volume (CTV) definition for the purpose of adjuvant irradiation of pelvic lymph nodes using intensity modulated radiotherapy (IMRT). [ Time Frame: once at time of imaging ]

Secondary Outcome Measures:
  • Comparison of target lymph node delineation between nodal imaging with USPIO and volume expansion of vascular anatomy. [ Time Frame: once at time of imaging ]
  • Demonstration of the pattern and distribution of pelvic nodal metastases in patients with uterine, cervical, bladder and prostate cancers. [ Time Frame: once at time of imaging ]

Enrollment: 61
Study Start Date: April 2004
Study Completion Date: June 2006
Primary Completion Date: June 2006 (Final data collection date for primary outcome measure)
Intervention Details:
    Procedure: MRI contrast agent Combidex (ferumoxtran-10)
    Combidex as an MR-lymph node contrast agent for the detection of small lymph nodes and lymph metastases.
