Aim: Rates of the newly-detected DCIS reach up to 20% in developed countries. There is no unified therapeutic scheme to deal with the disorder. The aim of this work is to assess the author’s own therapeutic results. Methodology: From 1999 until 2003, 11 female patients suffering from the DCIS were treated and 2 DCIS female patients were treated using microinvasion. The diagnosis was established 5× by the core-cut and 8× by the surgical excision. Results: The size of the tumors varied from 0.5 cm to 6.0 cm. Conservative procedures were performed 11 times, a simple mastectomy once and a mastectomy with reconstruction once, as well. The sentinel lymphonodes were examined in all cases and once the examination was accompanied by the axilla dissection. The number of the sentinel lymphonodes was 29. All of the lymphonodes were negative. Seven female patients were given a complementary therapy. All female patients have had no local relapse in the breast and have had no signs of the disease process since. The average follow-up time is 13.5 months. Conclusion: The conservative procedures sufficiently provide treatment of early forms of the DCIS of the breast. The sentinel lymphonode biopsy is a patient- kind method, giving exact information on the status of the axillary lymphonodes and it is considered a suitable part of the DCIS therapy.
