Postoperative Outcomes of One-Step Implant-Based Breast and Ovarian Surgery in High-Penetrance Gene Mutation: A Single-Center Experience

Background/Objectives: This study was designed to evaluate skin-sparing mastectomy with implant reconstruction complication rates in patients operated on due to high penetrant gene profile. All patients went to skin-sparing mastectomy with implant reconstruction and risk-reducing salpingo-oophorectomy. The effect of radiotherapy and chemotherapy on wound healing is a frequently discussed topic in the literature. However, studies on the effect of these on patients undergoing implant-based reconstruction are rare. In our clinic, two surgeries are performed under the same anesthesia and it is aimed to investigate the effect of this situation on complications in this rare patient group. In this retrospective study, we report our clinical experience regarding complication rates due to these factors among the high penetrant gene group. Methods: Between June 2022 and June 2024, 61 patients were grouped according to demographic data. Post-operative complications were defined as any of the following: major complications which were active bleeding or wound dehiscence; minor complications which were hematoma, seroma, surgical-site infection, <20% skin or nipple necrosis, and reoperation due to wound dehiscence or any other complication. Patients were compared in terms of complications according to whether they received previous radiotherapy (RT), neoadjuvant chemotherapy (CT), or underwent skin-reducing mammoplasty. Results: Patients receiving neoadjuvant chemotherapy, patients receiving preoperative RT, and patients undergoing skin-reducing mastectomy were compared in terms of major and minor complications. While neoadjuvant CT and preoperative RT only increased the risk of seroma, it was found that skin-reducing mastectomy had no significant effect on complication rates. Conclusions: Skin-sparing mastectomy with implant reconstruction and risk-reducing salphingo-oophorectomy is a comprehensive operation method in this patient group. Complication control can be achieved by performing two surgeries in a single anesthesia period, using the spy immunofluorescence device for vascularization control, and performing all surgeries with the same experienced team.
