Outcomes of Screening-Detected Ductal Carcinoma In Situ Treated with Wide Excision Alone

Background Ductal carcinoma in situ (DCIS) is commonly identified on screening mammography. Standard treatment for localized DCIS is wide local excision (WLE) and adjuvant radiotherapy. This approach represents overtreatment in many cases, where the DCIS would never have become clinically significant, or where less intensive treatment would have been satisfactory. We reviewed the medium-term outcome of a cohort of screen detected DCIS patients treated mainly with WLE without radiotherapy.
