Comparison of outcomes of standard and oncoplastic breast-conserving surgery.

[PURPOSE] The aim of this study is to determine and to compare the oncological outcomes of bilateral reduction mammoplasty to standard breast-conserving surgery for breast cancer.

[METHODS] One hundred sixty-two patients who received a quadrantectomy because of breast cancer (group 1) and 106 breast cancer patients with macromastia who underwent breast-conserving surgery via bilateral reduction mammoplasty (group 2) between 2003 and 2010 were enrolled in this study.

[RESULTS] The mean follow-up time was 37 months for group 1 and 33 months for group 2. Surgical margins were wider than 2 mm in 82.7% and 10 mm in 76.5% of the patients in group 1. Eleven percent of patients had positive surgical margins in this group. When compared to group 2, the rates were 89%, 84%, and 8.4%, respectively. Three patients (1.8%) in group 1 and one patient (0.9%) in group 2 had local recurrence of the disease and received a mastectomy. No statistical significances were noted for either local recurrence or overall survival between the two groups.

[CONCLUSION] Bilateral reduction mammoplasty has some advantages as compared to the standard conventional breast-conserving surgery techniques without having any unfavorable effects on surgical margin confidence, local recurrence, and survival rates.
