The axillary flap in oncoplastic resection of breast cancers located in the upper-outer quadrants: a new surgical technique

Abstract

Abstract Background The combination of breast conserving surgery (BCS) with plastic surgery techniques has provided a useful surgical tool matching the radicality of the oncological excision with the preservation of breast cosmesis. Even though BCS represents a good option for surgical treatment of tumors located in these quadrants, wide excisions often necessitate breast reshaping in order to avoid nipple areola complex (NAC) displacement and skin retraction. We present a new surgical technique to repair upper-outer quadrants’ defects following breast cancer excision using dermo-glandular flaps and an axillary adipo-fascial flap. Methods During the period from January 2014 to December 2015, 168 patients with an upper-outer quadrant’s breast cancer have been treated in our Department. 83 women have been treated with the described oncoplastic technique and immediate contra-lateral symmetrisation and 85 women underwent standard BCS. We present surgical, oncological and cosmetic outcomes comparing our results with standard BCS. Results At a mean follow-up of 27 months loco-regional recurrences in the two groups were comparable. Short-term complication rates were comparable between the two groups. Re-intervention rates for positive margins were significantly higher in the standard BCS group. The overall satisfaction with cosmetic outcome both assessed by the patient and the surgeon was significantly higher in the oncoplastic group. Conclusions The proposed oncoplastic technique represents a safe and effective solution for reshaping that follows upper-outer breast cancer wide excision, achieving comparable complication rates, lower re-intervention rates for positive margins and better cosmetic results when compared with standard BCS.
