Impact of Mastectomy Flap Necrosis on Patient-Reported Quality-of-Life Measures After Nipple-Sparing Mastectomy: A Preliminary Analysis.

ABSTRACT

BACKGROUND: Mastectomy skin flap necrosis (SFN) is common following nipple-sparing mastectomy (NSM), but studies on its quality-of-life (QOL) impact are limited. We examined patient-reported QOL and satisfaction after NSM with/without SFN utilizing the BREAST-Q patient-reported outcome measure (PROM) survey. PATIENTS AND METHODS: Patients undergoing NSM between April 2018 and July 2021 at our institution were examined; the BREAST-Q PROM was administered preoperatively, and at 6 months and 1 year postoperatively. SFN extent/severity was documented at 2-3 weeks postoperatively; QOL and satisfaction domains were compared between patients with/without SFN. RESULTS: A total of 573 NSMs in 333 patients were included, and 135 breasts in 82 patients developed SFN (24% superficial, 56% partial thickness, 16% full thickness). Patients with SFN reported significantly lower scores in the satisfaction with breasts (p = 0.032) and psychosocial QOL domains (p = 0.009) at 6 months versus those without SFN, with scores returning to baseline at 1 year in both domains. In the "physical well-being-of-the-chest" domain, there was an overall decline in scores among all patients; however, there were no significant differences at any time point between patients with or without SFN. Sexual well-being scores declined for patients with SFN compared with those without at 6 months and also at 1 year, but this did not reach significance (p = 0.13, p = 0.2, respectively). CONCLUSIONS: Patients undergoing NSM who developed SFN reported significantly lower satisfaction and psychosocial well-being scores at 6 months, which returned to baseline by 1 year. Physical well-being of the chest significantly declines after NSM regardless of SFN. Future studies with larger sample sizes and longer follow-up are needed to determine SFN's impact on long-term QOL.
