Abstract:Objective:To study the clinical outcome of breast conserving treatment of breast ductal carcinoma in situ(DCIS).
Methods :The data of 62 patients with pathologically proven DCIS who underwent breast conserving operation and adjuvant radiotherapy were retrospectively compared with 62 concurrent cases of stageⅠ or Ⅱ infiltrating ducatl carcinoma who received breast conserving operation and adjuvant readotherapy.
Results:The recurrence rate in DCIS cases was 6.4%(4/62), among them, 3 cases belonged to comedo type;the recurrence rate in early infiltrating type of ductal breast carcinoma was 19.3%(11/62)(P<0.05).
Conclusions:In cases of breast ductal carcinoma in situ, breast conserving treatment has better prognosis than early infiltrating ductal carcinoma. The comedo type has a high risk to recur.
