Abstract

Background and objectives: To report on the outcomes and evolution of an oncoplastic mammaplasty referred to as geometric compensation mammaplasty.

Methods: Seventy-three patients with malignant tumours were operated on and followed up in five centres in two countries. Preoperative markings were performed using a Wise pattern. The resection of affected skin was geometrically compensated using another area of preserved skin.

Results: Mean pathological tumour size was 30.42 ± 21.98 mm. Twenty tumours (30.77%) were locally advanced and 15 (20.55%) were multicentric. Twenty-two patients (34.38%) were submitted to neoadjuvant chemotherapy. Cosmetic results were considered good or excellent in 59 cases (80.82%). Margins were positive in two cases (2.74%). Complications were partial wound dehiscence (n = 11; 15.07%), fat necrosis (n = 9; 12.33%), skin necrosis (n = 5; 6.85%), seromas (n = 5; 6.85%), enlarged scars (n = 7; 9.59%) and infection (n = 2; 2.74%). There were three cases of local recurrence (4.29%), two of bone metastasis (2.86%) and three of metachronous contralateral breast cancer (4.35%). No deaths were recorded within a mean follow-up of 35.33 ± 28.21 months.

Conclusions: The technique allowed breast conservation in situations requiring a large resection of skin in difficult positions, with a high rate of free margins, correction of ptosis, satisfactory symmetry and few complications.
