Background: Following therapeutic mammoplasty (TM), the contralateral breast may require a later balancing procedure to optimize shape and symmetry. The alternative is to offer patients simultaneous TM with immediate contralateral symmetrization via a dual-surgeon approach, with the goal of reducing costs and minimizing the number of subsequent hospital appointments in an era of COVID-19 surges. The aim of this cost-consequence analysis is to characterize the cost-benefit of immediate bilateral symmetrization dual-operator mammoplasty versus staged unilateral single operator for breast cancer surgery., Method: A prospective single-centre observational study was conducted at an academic teaching centre for breast cancer surgery in the UK. Pseudonymized data for clinicopathological variables and procedural care information, including the type of initial breast-conserving surgery and subsequent reoperation(s), were extracted from the electronic patient record. Financial data were retrieved using the Patient-Level Information and Costing Systems., Results: Between April 2014 and March 2020, 232 women received either immediate bilateral (n = 44), staged unilateral (n = 57) for breast cancer, or unilateral mammoplasty alone (n = 131). The median (interquartile range (i.q.r.)) additional cost of unilateral mammoplasty with staged versus immediate bilateral mammoplasty was €5500 (€4330 to €6570) per patient (P < 0.001), which represents a total supplementary financial burden of €313 462 to the study institution. There was no significant difference between groups in age, Charlson comorbidity index, operating minutes, time to adjuvant radiotherapy in months, or duration of hospital stay., Conclusion: Synchronous dual-surgeon immediate bilateral TM can deliver safe immediate symmetrization and is financially beneficial, without delay to receipt of adjuvant therapy, or additional postoperative morbidity., (© The Author(s) 2022.

Background: Radiotherapy before mastectomy and autologous free-flap breast reconstruction can avoid adverse radiation effects on healthy donor tissues and delays to adjuvant radiotherapy. However, evidence for this treatment sequence is sparse. We aimed to explore the feasibility of preoperative radiotherapy followed by skin-sparing mastectomy and deep inferior epigastric perforator (DIEP) flap reconstruction in patients with breast cancer requiring mastectomy., Methods: We conducted a prospective, non-randomised, feasibility study at two National Health Service trusts in the UK. Eligible patients were women aged older than 18 years with a laboratory diagnosis of primary breast cancer requiring mastectomy and post-mastectomy radiotherapy, who were suitable for DIEP flap reconstruction. Preoperative radiotherapy started 3-4 weeks after neoadjuvant chemotherapy and was delivered to the breast, plus regional nodes as required, at 40 Gy in 15 fractions (over 3 weeks) or 42·72 Gy in 16 fractions (over 3·2 weeks). Adverse skin radiation toxicity was assessed preoperatively using the Radiation Therapy Oncology Group toxicity grading system. Skin-sparing mastectomy and DIEP flap reconstruction were planned for 2-6 weeks after completion of preoperative radiotherapy. The primary endpoint was the proportion of open breast wounds greater than 1 cm width requiring a dressing at 4 weeks after surgery, assessed in all participants. This study is registered with ClinicalTrials.gov, NCT02771938, and is closed to recruitment., Findings: Between Jan 25, 2016, and Dec 11, 2017, 33 patients were enrolled. At 4 weeks after surgery, four (12·1%, 95% CI 3·4-28·2) of 33 patients had an open breast wound greater than 1 cm. One (3%) patient had confluent moist desquamation (grade 3). There were no serious treatment-related adverse events and no treatment-related deaths., Interpretation: Preoperative radiotherapy followed by skin-sparing mastectomy and immediate DIEP flap reconstruction is feasible and technically safe, with rates of breast open wounds similar to those reported with post-mastectomy radiotherapy. A randomised trial comparing preoperative radiotherapy with post-mastectomy radiotherapy is required to precisely determine and compare surgical, oncological, and breast reconstruction outcomes, including quality of life., Funding: Cancer Research UK, National Institute for Health Research., Competing Interests: Declaration of interests PTRT reports personal fees from Stryker Surgical and Cytoveris.

Abstract: Mastectomy and immediate reconstruction may be challenging in patients with large breasts, especially when significant ptosis is also present. Skin-reducing mastectomy (SRM) is usually indicated in these cases, although with increased morbidity. The aims of the study were to introduce 2 modifications of the classic technique and to incorporate them in the management algorithm to improve the outcomes.Twenty patients fulfilling the criteria for SRM underwent mastectomy and reconstruction either with the "classic SRM" (8 patients) or with 1 of the 2 modifications described here: modification A "vertical limb bridging" (for patients with very large breasts, 2 patients) and modification B "dual coverage" (for patients with moderate breasts, 10 patients). All reconstructions were performed using a slow progressive expansion of the implant. Herein, we describe the techniques along with the proposed indications for each one of them.There was no reconstruction failure, and all patients were satisfied with the final results. There were 2 cases with T junction, lateral skin flap partial ischemia managed with delayed revision of the wound on the fifth postoperative day to allow less skin excision. One patient (smoker) developed severe lower pole cellulitis, which was managed conservatively. Finally, 1 patient who underwent radiotherapy developed a late infected seroma, which was managed successfully with drainage and antibiotics. Overall, there was good lower pole projection even with the dual-coverage modification.Skin-reducing mastectomy can be tailored according to individual patient anatomy, and the high reported complication rate associated with this technique can be minimized using certain surgical modifications, tissue expanders with progressive inflation, and good patient selection., Competing Interests: Conflicts of interest and sources of funding: none declared., (Copyright © 2021 Wolters Kluwer Health, Inc.
