Abstract

Abstract: Aim: For large breast tumours, therapeutic mammoplasty (TM) provides a breast-conserving approach to the conventional mastectomy. The prevalence and outcomes following TM in larger breast tumours is relatively unknown. This study aims to analyse the short-term outcomes and local recurrence rate following TM for breast tumours of varying sizes. Method: Single-centre retrospective analysis of data from all patients undergoing a TM between June 2016-October 2019. Variables reviewed included age, imaging, tumour size, pre-operative histology, adjuvant chemotherapy and radiotherapy, post-operative pathology, post-operative complications, and recurrence rates. Results: 192 patients undergoing a TM procedure were included, 126 (66%) patients had tumours <40mm and 66 (34%) patients had tumours > 40mm. The average age of participants was 61 years with a mean follow-up of 31 months. The mean size of tumours > 40mm was 56.8mm, of these patients 15% had positive margins, 2 (3%) patients required a further mastectomy and 8 (12%) underwent margin re-excisions. In lesions > 40mm there were six episodes (9%) of T-junction delayed wound healing with two requiring surgical management, two episodes (3%) of wound infections requiring antibiotics and four episodes (6%) of seroma with one requiring surgery for an infected seroma. Two patients were found to have metastatic disease and no patients were found to have local recurrence at the most recent follow-up. Conclusions: Our study demonstrated TM offers a surgical option with suitable cosmetic and oncological outcomes for women with early breast tumours above 40mm. These results warrant further study into the long-term outcomes for patients undergoing TM with tumours > 40mm.
