Ductal carcinoma in situ of the breast: our experience.
OBJECTIVE
The ductal carcinoma in situ (DCIS) is a more and more frequent neoplasia, representing over 25% of diagnosed breast cancer in recent surveys.It is particularly interesting as concerns several aspects of which the most important are issues linked to clinical diagnosis and the difficulties of histopathological classification, with evident and important therapeutic implications.


METHODS
The authors report their experience about 161 ductal carcinoma in situ of the breast. Guidelines for surgical treatment are: radiological or clinical diagnosis, tumor's extension, histological classification, grading and margin status. At the present the authors prefer breast conserving surgery with tumor margin's study. They report their experience in the last seven years about sentinel lymph node biopsy.


RESULTS
The most frequent histotype resulted comedocarcinoma (61,8%) followed by non comedo (38,2%). Local recurrence after DCIS therapy is 6,1%.


CONCLUSIONS
80-90% of the patients currently treated for DCIS present non-palpable breast lesions at diagnosis. Breast conserving surgery is the first choice and radiotherapy and endocrine therapy are indicated for selected patients.
