Variation in type II endometrial cancer risk by Hispanic subpopulation: An exploratory analysis

Minorities have demonstrated an increased risk for type II endometrial cancers, but no data exists about risk among minority subpopulations. Our objective was to evaluate heterogeneity in risk of type II endometrial cancer (EC) histologies across race and Hispanic sub-groups using data from Florida's statewide cancer registry (FCDS). Methods FCDS contains data on N=26,416 women diagnosed with EC from 2004 to 2013. Our analysis included women ≥18years of age who were classified as non-Hispanic White (NHW), non-Hispanic Black (NHB) or belonged to one of five Hispanic sub-groups, and had a histology code consistent with type I or type II EC. Binary logistic regression analyses were performed to model risk of type II versus type I ECs across racial and ethnic groups relative to NHW. Results Relative to NHW, overall odds of being diagnosed with a type II EC were significantly higher in NHB (OR=2.64, 95%CI: 2.38–2.92), Cubans (OR=1.35, 95%CI: 1.08–1.68) and South and Central Americans (SCA) (OR=1.84, 95%CI: 1.40–2.43). Compared to NHW, odds of serous EC were significantly higher in Cubans (OR=2.15, 95% CI: 1.51–3.05) and NHB (OR=2.51, 95% CI: 2.11–2.97); odds of carcinosarcoma (CS) were significantly higher in NHB (OR=2.97, 95% CI: 2.47–3.57) and Puerto Ricans (OR=2.35, 95%CI: 1.32–4.17); and odds of grade III adenocarcinoma (AG3) were significantly higher in NHB (OR=1.60, 95% CI: 1.42–1.81) and SCA (OR=1.76, 95%CI: 1.29–2.40). Conclusion Risk of type II EC varies considerably across Hispanic sub-groups, with Cubans, Puerto Ricans and SCA characterized by elevated odds for specific type II histologies.
