Objective
To better understand national patterns of invasive cervical cancer (ICC) incidence by race and ethnicity in order to develop
appropriate ICC prevention policies.
Methods
Age-adjusted and age-specific ICC incidence rates were calculated by combined race/ethnicity, making distinct the Hispanic/all
races category from three other Non-Hispanic (White, Black and other) racial categories.
Results
There was a significant downward trend in ICC incidence during both time periods for every combination of race/ethnicity (p-value <0.05) except Hispanic/all races during 1995–1999. Non-Hispanic/Black and Hispanic/all races women had significantly
higher incidence rates of ICC compared to Non-Hispanic/White women. ICC incidence peaked much earlier for Non-Hispanic/White
women (35–44 years of age) compared to any other racial/ethnic group. Non-Hispanic (White, Black and other) women had lower
rates of adenocarcinoma and squamous cell carcinoma compared to Hispanic/all races women. Non-Hispanic/Black and Hispanic/all
races women were more likely to be diagnosed at late stage or unstaged at diagnosis than Non-Hispanic/White women.
Conclusion
Although ICC incidence decreased significantly over the last 10 years, Black or Hispanic US populations continue to have the
highest ICC incidence compared to Non-Hispanic/Whites, highlighting the need for improved health literacy and social support
to ensure their equal access to ICC screening and HPV prevention including HPV vaccination.
