Three-dimensional Simulation on Patient-reported Outcomes Following Oncoplastic and Reconstructive Surgery of the Breast: A Randomized Trial

Abstract

Background:. Three-dimensional (3D) imaging using computer simulations is an evolving technology. There is a lack of strong data on the use of this technology for oncoplastic (OP) and reconstructive surgery. Methods:. A prospective, randomized, single-center trial including breast cancer patients undergoing OP or mastectomy with immediate breast reconstruction with implant (IBR) enrolled from November 2019 to October 2021 at the Hospital Nossa Senhora das Graças, Breast Unit in Curitiba, Brazil. Both patients undergoing OP and those in the IBR group were randomized to undergo 3D imaging and simulation of postoperative results (intervention group) or 3D imaging without simulation (control group). All patients were invited to complete a patient-reported outcome (BREAST-Q) expectations module and breast reconstruction or reduction/mastopexy module before and 6 months after surgery. Results:. A total of 96 patients were enrolled. Sixty-nine patients (45 OP and 24 IBR) completed the pre- and postoperative questionnaires and were randomized for the simulation. Women in the OP group had higher expectations for breast appearance when clothed than those in the IBR implant group (93.4 ± 16.3 versus 82.9 ± 26.5; P = 0.03). The intervention group was more satisfied with information than the control group (P = 0.021). Both patients who underwent OP and IBR believed that the 3D simulation helped them understand the surgical process (86.6% and 75%, respectively). Conclusions:. Preoperative 3D simulation significantly improved patient’s satisfaction with information and did not decrease postoperative satisfaction with the outcomes. The incorporation of preoperative 3D simulation may be a valuable tool in breast reconstruction.
