[Standards, Options and Recommendations for the management of ductal carcinoma in situ of the breast (DCIS): update 2004].

The " Standards, Options and Recommendations " (SOR) project, started in 1993, is a collaboration between the Federation of French Cancer Centres (FNCLCC), the 20 French cancer centres, and specialists from French public universities, general hospitals and private clinics. The main objective is the development of clinical practice guidelines to improve the quality of health care and the outcome of cancer patients. The methodology is based on a literature review and critical appraisal by a multidisciplinary group of experts, with feedback from specialists in cancer care delivery.

[Management of ductal carcinoma in situ by the pathologist: current questions].

As a consequence of increased screening mammography, ductal carcinoma in situ represents a growing percentage of breast cancer diagnoses.

In this Article, we describe the diagnostic criteria of these lesions as well as the histopathological characteristics of their two principal differential diagnoses: atypical ductal hyperplasia and micro-infiltrating carcinoma.
