Oncological Outcome and Patient's Satisfaction of Skin-Sparing Mastectomy and Immediate Breast Reconstruction: A Prospective Observational Study.

Abstract

Abstract INTRODUCTION: The management of early breast cancer with skin-sparing mastectomy (SSM) and immediate breast reconstruction (IBR) is not based on evidence from randomised controlled trials. The purpose of this study is to evaluate the oncological safety, post-operative morbidity and patients' satisfaction with SSM and IBR using the latissimus dorsi (LD) myocutaneous flap and/or breast prosthesis. METHODS: One hundred and twenty five consecutive women underwent 137 SSMs with IBR (12 bilateral), using the LD flap plus implant (n=85) or implant alone (n=42), indications included breast cancer (n=130)and prophylaxis (n=7). Most tumours (99.2%) were Tis, T1, or T2 and only one tumour was T3 stage. Nipple reconstruction was performed in 69 patients, using a small local flap technique (n=61), nipple sharing (n=6), free skin graft (n=1) or Monocryl mesh (n=1). Thirty patients underwent contra-lateral surgery in order to optimise symmetry, including 19 augmentations and 11 mastopexy/reduction mammoplasties. Patient satisfaction with the outcome of surgery was assessed on a linear visual analogue scale ranging from 0 (not satisfied) to 10 (most satisfied). RESULTS: There was no local recurrence (LR) after a mean follow-up of 33.2 months (range=3-98 months). Overall survival was 99.2%, seven patients developed distant disease and one patient died of metastatic breast cancer. No case of partial or total LD flap loss was observed. Morbidities included infection, requiring implant removal in two patients and one patient developed marginal ischaemia of the skin envelope. Significant capsule formation, requiring capsulotomy, was observed in 87% of patients who had either PMR or prior RT compared with 13% for those who did not have RT. Eighty two (65.6%) of 125 patients completed the questionnaire with a median satisfaction scores of 9 (range=5-10). CONCLUSION: SSM with IBR is associated with low morbidity, high levels of patient satisfaction and is oncologically safe for T(is), T1 and T2 tumours without extensive skin involvement.
