Overview

Aim of this trial is to verify whether the patients' quality of life can be improved by a less invasive surgical procedure and whether the use of robotic technique for nipple-sparing mastectomy associated to prepectoral direct implant procedure can impact on perioperative and postoperative period and on oncologic outcome.

Muscle coverage, whether total or partial, has been historically advocated as the preferred approach after nipple sparing mastectomy because it adds an additional layer of vascularized coverage to the implant. However, current practices have evolved toward prepectoral implant reconstruction as it reduces animation deformity, pain, and muscle spasms, compared with the subpectoral approach, while maintaining optimal esthetic results. One of the limitations to the use of the prepectoral (subcutaneous) implant in ordinary surgery (open technique) is related to the fact that the implant is in direct contact with the surgical wound, giving reasons of high rate of implant loss due to wound dehiscence. In this sense, the extra-mammary localization of the surgical wound (as during robotic mastectomy) allows the positioning of the prepectoral implant in greater safety. Robotic nipple-sparing mastectomy with immediate breast prepectoral implant reconstruction may allow for more precise anatomic dissection and improved cosmetic outcomes over conventional open nipple-sparing mastectomy with retro-pectoral implant reconstruction; however, data about the feasibility, safety of the prepectoral reconstruction is limited as well as Quality of Life (QoL) evaluation. The aim of this single center, prospective trial is to analyze the perioperative data, postoperative complications, oncologic outcomes as well as to analyze the patient reported outcome measures (PROMs) of 24 consecutive patients undergoing robotic nipple-sparing mastectomy and reconstruction with prepectoral implant. Concomitant endpoint is to compare operative features outcome measures and post-operative outcome complications. A second-phase time line is to evaluate the long-term analysis of cumulative incidence of loco-regional recurrence, distant recurrences, the disease free survival and the overall survival with a median follow up of 5 years.
