To examine racial/ethnic disparities in stage of disease and comorbidity (pre-treatment), surgical treatment allocation (breast-conserving surgery versus mastectomy), and in-hospital outcomes after surgery (post-treatment) among women with breast cancer. Nationwide inpatient sample is a nationwide clinical and administrative database compiled from 44 states representing 95 % of all hospital discharges in the Unites States. Discharges of adult women who underwent surgery for breast cancer from 2005 to 2009 were identified. Information about patients and hospitals characteristics was obtained. Multivariate logistic regression analyses were used to examine the risk adjusted association between race/ethnicity and the aforementioned outcomes (pre-treatment, treatment, and post-treatment). We identified 75,100 patient discharges. Compared to Whites, African-Americans (1.17, p < 0.001), and Hispanics (1.20, p < 0.001) were more likely to present with regional or metastatic disease. Similarly, African-American (1.58, p < 0.001) and Hispanics (1.11, p 0.003) were more likely to have comorbidity. Compared to Whites, African-Americans (0.71, p < 0.001), and Hispanics (0.77, p < 0.001) were less likely to receive mastectomy. Compared to Whites, African-Americans were more likely to develop post-operative complications (1.35, p < 0.001) and in-hospital mortality (1.87, p 0.13). Other racial groups showed no statistically significant difference compared to Whites. After controlling for potential confounders, we found racial/ethnic disparities in stage, comorbidity, surgical treatment allocation, and in-hospital outcomes among women with breast cancer. Future researches should examine the underlying factors of these disparities.
