P2-15-13: Oncologic and Cosmetic Outcome in Breast Cancer Patients Who Underwent “Moving Window” Operation.

Abstract

Background: An inappropriate skin incision on the breast reduces the cosmetic benefit of breast-conserving surgery (BCS). Methods: To improve the cosmetic outcome, we have performed “Moving window” operation in which BCS can be performed via a periareolar incision (periareolar approach) and/or axillary incision (axillary approach) under direct visualization. Axillary lymph node dissection is also performed via an axillary incision. Results: Periareolar approach was performed in 65 patients and axillary approach in 43 patients. Average operation time was 130 minutes in periareolar approach and 131 minutes in axillary approach. Average blood loss was 37 mL and 50 mL, respectively. Postoperatively, the surgical margin of breast tissue was histologically confirmed to be negative in 107 (99%) of 108 patients, while two patients underwent reoperation because of positive surgical margin. Fifty-two patients (85%) in periareolar approach and 37 patients (86%) in axillary approach had excellent or good cosmetic results. With a mean follow-up of 36 months, one patient with DCIS developed in-breast recurrence, while 3 patients who had neoadjuvant chemotherapy developed in-breast recurrence. Conclusion: The moving window operation can improve a cosmetic outcome of the conserved breast without compromising the oncological safety. Moreover, it can reduce operating time and blood loss when compared with the endoscope-assisted BCS. Citation Information: Cancer Res 2011;71(24 Suppl):Abstract nr P2-15-13.
