Nipple-sparing bilateral prophylactic mastectomy and immediate reconstruction with TiLoop ® Bra mesh in BRCA1/2 mutation carriers: A prospective study of long-term and patient reported outcomes using the BREAST-Q.

BACKGROUND: Although demand for prophylactic mastectomy is increasing over time among women at a high risk for breast cancer, there is a paucity of studies on long term patient-reported outcomes after this procedure.

METHODS: Between January 2011 and January 2015, 46 patients documented BRCA1/2 mutation carriers, eligible for prophylactic nipple-sparing mastectomy (NSM) and immediate breast prosthetic reconstruction were registered at our Institution. Patients underwent NSM and subcutaneous reconstruction with implant covered by a titanium-coated polypropylene mesh (TiLoop® ). The BREAST-Q questionnaire was given to patients prior to surgery and at 1 and 2 years follow-up points. Capsular contracture was evaluated by Baker scale. Surgical outcomes along with the changes in BREAST-Q score were analyzed over time.

RESULTS: Complications were reported in only one case and after two years the capsular contracture rates were acceptable (grade I: 65,2%; grade II: 32,6%; grade III 2,2%). At one year and two year follow-ups patients reported high rates in the measures of overall satisfaction with breasts (72,5 and 73,7 respectively), psychosocial well-being (78,4 and 78,6), sexual well-being (58,8 and 59,4), physical well-being (77,6 and 80,6) and overall satisfaction with outcome (75,7 and 79,7). A statistically significant increase in all BREAST-domains from the preoperative to the postoperative period was reported at one and two years follow-ups (p < 0,05).

CONCLUSION: Following bilateral prophylactic NSM and immediate subcutaneous reconstruction with TiLoop® , patients demonstrated high levels of satisfaction and quality of life as measured by BREAST-Q. 2-years outcomes confirmed high patient comfort with increased scores from the preoperative baseline level.
