- Abstract
Background: Ductal carcinoma in situ (DCIS) represents 15% of all breast cancers in France. The first national survey was conducted in 2003. The present multi-center real-life practice survey aimed at assessing possible changes in demographic, clinical, pathologic, and treatment features., Material and Methods: From March 2014 to September 2015, patients diagnosed with DCIS from 71 centers with complete information about age, diagnostic features, and treatment modalities were prospectively included., Results: A total of 2125 patients with a median age of 58.6 years from 71 centers were studied. DCIS was diagnosed by mammography in 87.5% of cases. Preoperative biopsy was performed in 96% of cases. The median tumor size was 15 mm. Nuclear grade was low, intermediate, and high in 12%, 36%, and 47% of cases, respectively. Margins were considered to be negative in 83% of cases. Overall mastectomy and lumpectomy rates were 25% and 75%, respectively. The immediate breast reconstruction rate was 50%. Sentinel node biopsy and axillary dissection rates were 41% and 2.6%, respectively. After lumpectomy, 97% of patients underwent radiotherapy, and 32% received a boost dose. Only 1% of patients received endocrine therapy. Compared with our previous survey, the median tumor size remained the same, and the proportion of high-grade lesions increased by 9%. The mastectomy rate decreased by 4%., Conclusions: The clinical practice identified in this survey complies with French DCIS guidelines. About 10% of patients with low-grade DCIS may be eligible to participate in treatment de-escalation trials., (Copyright © 2019 The Authors. Published by Elsevier Inc. All rights reserved.)
