Study information
Scientific title
Duct endoscopy in the evaluation of breast cancer and surgical margins
Acronym
INTEND I (intraoperative endoscopic evaluation of duct epithelium)
Study hypothesis
This project seeks to clarify the future role of breast duct endoscopy versus no duct endoscopy as an adjunct to surgery in a randomised controlled trial. The procedure enables cancer duct systems to be directly visualised. We will test an observation that the re-operation rate for margins involved by cancer can be reduced by inspection of the ducts at the time of surgery. We intend to evaluate the feasibility of this approach by assessing whether the ducts that yield fluid, that can be accessed, have an anatomic relationship with the tumour position.
On 17/02/2011 the following changes were made to the trial record:
1. The anticipated end date for this trial was changed from 31/12/2009 to 31/08/2011.
2. The target number of participants was changed from 150 to 176.
