Targeted Intraoperative Radiotherapy for the Management of Ductal Carcinoma in Situ of the Breast also known as the TARGIT-DCIS Trial is a phase II clinical trial designed to examine the safety and efficacy of intraoperative radiotherapy (IORT) for the management of DCIS. 

The study began in 2007 and has completed recruitment and analysis.

Primary Objective

To determine if patients with pure DCIS considered eligible for concurrent

IORT at the time of surgery based on preoperative mammography and contrast-enhanced magnetic resonance imaging (CE-MRI) could be successfully treated using IORT with minimal need for additional therapy due to inadequate surgical margins or excessive tumor size.

Study Status

Recruitment Completed, Results Published, Follow-Up Ongoing
