AbstractIntroduction: Women with breast cancer related genetic pathogenic variants (e.g. BRCA1, BRCA2) or with a strong family history carry lifetime risks of developing breast cancer of up to 80-90%. A significant proportion of these women proceed to bilateral risk reducing mastectomy (RRM). We aimed to document the surgical morbidity of RRM and establish whether a diagnosis of breast cancer at the time of surgery impacted on outcomes. Methods: Clinical details of 445 women identified as having >25% lifetime risk of developing breast cancer who underwent RRM and breast reconstruction were interrogated for surgical outcomes such as planned, unplanned and emergency procedures, complication rates, length of stay and longevity of breast reconstruction. These outcome measures were recorded in women diagnosed with breast cancer perioperatively (cancer group, CG) and those without malignancy (benign group, BG). Results: Median follow up was similar in both groups (BG, 70months; CG 73 months). Patients were older in the CG than BG (43y v 39y; p<0.001). Women in the CG required more planned procedures to complete reconstruction than those in the BG (4 v 2; p=0.002). Emergency procedures, unplanned surgical interventions (e.g. capsulectomy) and post reconstruction complication rates were similar between groups.One in five women overall required revisional surgery. Patients with autologous reconstructions had a revision rate of 1.24/1000 person years compared with 2.52 in the implant reconstruction group. Conclusion: Women contemplating RRM can be reassured that this a safe and effective procedure but will likely take multiple interventions. This knowledge should be integral to obtaining informed consent.
