78 Background: Despite mandated private insurance coverage for breast reconstruction following mastectomy, health care costs are increasingly passed onto women who seek these procedures through cost-sharing arrangements and high-deductible health plans. In this population-based study, we sought to characterize financial and employment toxicities related to pursuing breast reconstruction following mastectomy. Methods: Women (white, African American, and Latina-English and Spanish speaking) with early stage breast cancer (stages 0-II) diagnosed between July 2013 to September 2014 and who underwent mastectomy were identified through the Georgia and Los Angeles Surveillance, Epidemiology, and End Results (SEER) registries and surveyed. Primary outcome measures included patient-reported appraisal of financial toxicity and employment status following breast cancer treatment using previously developed measures. Multivariable models evaluated the association between breast reconstruction and self-reported financial and employment status. Results: Among 868 breast cancer patients who underwent mastectomy, 43.5% (n = 378) did not undergo breast reconstruction and 56.5% (n = 490) underwent reconstruction. 43.4% of the cohort reported being worse off financially since their diagnosis (49.4% with reconstruction vs. 35.0% without reconstruction, P< .001). Among women who were employed at time of breast cancer diagnosis (n = 535), 70.2% who underwent reconstruction reported being worse off regarding employment status compared to 51.1% who did not undergo reconstruction ( P< .001). Receipt of reconstruction was independently associated with a self-reported decline in financial status (Odds Ratio (OR) 2.1, 95% Confidence Interval (CI) 1.4-3.4, P= .001). Similarly, reports of being worse off regarding employment status were also higher in those who underwent reconstruction vs. not (OR 2.2, 95% CI 1.2-3.8, P= .006). Spanish-speaking Latina women more often reported being worse off regarding employment status (OR 4.3, 95% CI 2.1-9.0, P< .001) than white women. Conclusions: In this diverse cohort of women who underwent mastectomy for early stage breast cancer, women who elected to undergo reconstruction experienced more self-reported financial and employment toxicities. Patients should be counseled regarding the potential costs related to these procedures. Policy-makers should be aware of the financial barriers for women who undergo reconstruction despite mandatory insurance coverage in the United States.
