Ductal carcinoma in situ diagnosis: 3 French national guidelines

Objective. - Since the last guidelines published by the French National Cancer Institute (INCa) and the learning society ``Societe francaise de senologie et de pathologie mammaire (SFSPM)'' in 2009 about diagnosis and management of ductal carcinoma in situ, new data raised issues about overdiagnosis and its consequences, overtreatment. Therefore, an update was necessary, to provide healthcare professionals up-to-date guidelines and study therapeutic desescalation in particular. Methods. - The clinical practice guidelines development process is based on systematic literature review and critical appraisal by a multidisciplinary experts workgroup. The recommendations are thus based on the best available evidence and experts agreement. Prior to publication, the guidelines are also reviewed by more than 100 independent practitioners in cancer care delivery. Results. - This article presents French guidelines about MRI and vacuum assisted breast biopsy indications for DCIS diagnosis and the management of low-grade DCIS.
