Pilot Studie of Lipiodol Demarcation of the Tumour in Bladder Cancer

December 4, 2015 updated by: University of Aarhus

Lipiodol Demarcation of the Bladder Tumour in Adaptive Image-guided Radiotherapy: A Pilot Study. (Danish: Lipiodol Til Markering af blæretumoren i Forbindelse Med Adaptiv Billedvejledt strålebehandling: Et Pilotstudie.)

Rationale: Bladder tumours are often not visible on X-ray based image-modalities during planning and treatment of Radiotherapy.

Purpose: To determine if a single contrast (Lipiodol) demarcation of the bladder tumour before treatment is feasible and visible on multiple X-ray based image-modalities during Radiotherapy.

Detailed Description

To exploit the potential of modern Radiotherapy (RT), it is important to localize and follow the target precisely during treatment. Since the bladder tumour can usually not be identified on conventional CT-scan, a fiducial or contrast marking system is warranted.

The iodized oil, Lipiodol is a well-known contrast media used mainly for lymphography and Hysterosalpingography. Local Lipiodol demarcation has been used for localisation of tumours in the lung, prostate and seminal vesicles visualised on Computed Tomography (CT) and fluoroscopy.

Purpose: To evaluate the feasibility of tumour demarcation using the contrast agent Lipiodol in adaptive Image-guided RT of bladder cancer. Visibility on CT, Cone-Beam CT, MRI and on-board imaging will be evaluated.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: 1
Other: Lipiodol demarcation of the bladder tumour
1-3 drops of Lipiodol Ultra Fluid (iodine 38%W/W) will be injected into the submucosa on 4 locations around the bladder tumour. The procedure is done once during a planned cystoscopy approximately a week before the planning CT.
