title: Recurrence rates in patients with central or retroareolar breast cancers treated with mastectomy or lumpectomy.
abstract: BACKGROUND
  Although breast conservation with lumpectomy and radiation treatment has become a commonly used treatment for breast cancer, there are little data to support the use of lumpectomy for central and retroareolar breast cancers. In this study, we investigate the local and distant recurrence rates of patients with central or retroareolar breast cancers treated with lumpectomy compared with mastectomy.
  
  
  METHODS
  This study provides a retrospective analysis of 99 patients, from 1981 to 2000, with central or retroareolar breast cancers treated with mastectomy or lumpectomy to determine the frequency of local and distant recurrence. The mastectomy and lumpectomy patients were compared with respect to recurrence and other prognostic factors including: tumor location, tumor size, axillary nodal status, and final surgical margins.
  
  
  RESULTS
  The overall frequency of local recurrence was 5 of 99 (5.0%) in the entire group, 3 of 67 (4.5%) and 2 of 32 (6.3%) of patients who underwent mastectomy and lumpectomy, respectively (P >0.99). Overall, 3 patients experienced a distant recurrence as a first event, with 2 patients (3.0%) in the mastectomy group and 1 patient (3.1%) in the lumpectomy group (P >0.99). The type of surgical management was not statistically significant related to either local or distant disease recurrence, with median time to local recurrence of 3.0 years for the mastectomy patients and 5.0 years for lumpectomy patients. Of the patients with central tumors who underwent mastectomy 2 of 42 (4.8%) developed local recurrences compared with those who had a lumpectomy, 1 of 21 (4.8%). Similarly for retroareolar tumors, the local recurrence rate was 1 of 25 (4.0%) for patients undergoing mastectomy and 1 of 11 (9.1%) for those undergoing lumpectomy (P >0.99).
  
  
  CONCLUSIONS
  In this study there was no significant difference in local or distant failure rates of those patients with central or retroareolar tumors treated with mastectomy versus lumpectomy. We conclude lumpectomy to be a reasonable treatment option for selected patients with central or retroareolar breast cancers.
