Due to the rapid development of breast cancer screening and its detection more often in earlier stages, preinvasive forms of breast cancer account for up to 20% of all forms of malignant neoplasms of the breast. Therefore, today in the treatment of breast cancer with ductal carcinoma in situ (DCIS) there is a tendency to de-escalate surgical intervention. This article reviews the literature, as well as current domestic and international clinical guidelines for the treatment of DCIS in order to study the frequency of detection of metastatic lesions during sentinel lymph node examination (SLNB), and assesses the feasibility and indications for SLNB. The findings of the current review article can supplement the existing data on the indications for SLNB in patients with DCIS and help clarify the recommendations for the treatment of ductal carcinoma in situ (DCIS).
