title: [Treatment analysis of 26 patients with breast ductal carcinoma in situ].
abstract: OBJECTIVE
  To study the appropriate surgical treatment for breast ductal carcinoma in situ (DCIS).
  
  
  METHODS
  Twenty-six such patients treated between 1992 and 2001 were retrospectively analyzed. Among them, 3 patients were treated by simple mastectomy, 23 patients by mastectomy and axillary lymph node dissection, 8 patients by chemotherapy and one patient by radiotherapy after operation. Median follow-up was 42 m (rang 12 - 112 m).
  
  
  RESULTS
  Except 3 of these 26 patients lost in follow-up and 1 patient died from diabetes mellitus, all the other 22 patients survived over 5 years. All lymph nodes dissected from 23 patients were negative. After surgery, 3 patients developed lymph edema of the arm.
  
  
  CONCLUSIONS
  DCIS, lacking the potential of metastasis, is not invasive. Conservative breast surgery without lymph node dissection is feasible for most DCIS patients.
