Condition: Muscle-invasive Bladder Cancer

Study Type: Interventional

Clinical Trials Identifier NCT 8-digits: NCT02462239

Sponsor: Ontario Clinical Oncology Group (OCOG)

  • Predominant histology (>50% of specimen) involves non-urothelial cell carcinoma.
  • Prior partial cystectomy.
  • Prior pelvis surgery that obviates a completed extended lymphadenectomy (e.g., aorto-femoral/iliac bypass) or for whom the surgeon feels that their ability to perform a standard or extended pelvic node dissection would be compromised.
  • Contraindications to FDG PET-CT.
  • Inability to lie supine for imaging with PET-CT.
