NHB patients with private or Medicare insurance were less likely to undergo resection and to receive adjuvant chemotherapy compared to similarly insured NHW patients.

NHB patients were less likely to undergo resection 0.61 to 0.72, p < 0.001] or to receive adjuvant chemotherapy compared to NHW patients. Confounders included sex, age, median income, rurality, comorbidity, and nodes and margin status for the model for chemotherapy. Multivariable regression with generalized estimating equations (GEEs) were performed to evaluate the association of insurance and race/ethnicity with odds of receipt of surgery (stage I to III) and adjuvant chemotherapy (stage III), with an additional 2-way interaction term to evaluate for effect modification.

In this cross-sectional study, patients diagnosed with stage I to III CC in the United States were identified from the National Cancer Database (NCDB 2006 to 2016).
