Background: Following passage of the Women's Health and Cancer Rights Act (WHCRA), a steady rise in breast reconstruction rates was reported; however, a recent update is lacking. This study aimed to evaluate longitudinal trends in breast reconstruction (BR) rates in the U.S. and relevant sociodemographic factors.
Methods: Mastectomy cases with/without BR from 2005 through 2017 were abstracted from the National Surgical Quality Improvement Program (NSQIP), Surveillance, Epidemiology, and End Results (SEER) Program, and National Cancer Database (NCDB). BR rates were examined using Poisson regression. Multivariable logistic regression analysis of NCDB data was used to identify predictors of reconstruction. Race and insurance distributions were evaluated over time.
Results: Of 1,554,381 mastectomy patients, 507,631 (32.7%) received BR. Annual reconstruction rates per 1000 mastectomies increased from 2005 to 2012 (NSQIP: Incidence Rate Ratio (IRR) 1.077; SEER: 1.090; NCDB: 1.092) and stabilized from 2013 to 2017. NCDB data showed that patients who were younger (≤59 years), privately insured, had fewer comorbidities, and underwent contralateral prophylactic mastectomy were more likely to undergo BR (all p<0.001). Over time, the increase in BR rates was higher among Black (252.3%) and Asian (366.4%) patients than White patients (137.3%). BR rates increased more among Medicaid (418.6%) and Medicare (302.8%) patients than privately insured (125.3%) patients.
Conclusions: This analysis demonstrates stabilization in immediate BR rates over the last decade; reasons behind this stabilization are likely multifactorial. Disparities based on race and insurance type have decreased, with a more equitable distribution of BR rates.
