Recent trends in cervical cancer incidence, stage at diagnosis, and mortality according to county‐level income in the United States, 2000–2019

Abstract Early evidence suggests that declining cervical cancer incidence reversed in low‐income regions in the United States in recent years; however, it is unclear whether there are distinct patterns by race/ethnicity and stage at diagnosis and if the increase has translated into rising mortality. Using Surveillance, Epidemiology, and End Results data, we evaluated trends in hysterectomy‐corrected cervical cancer incidence rates (2000–2019) and mortality rates (2005–2019) by county‐level income and race/ethnicity, with further stratification of incidence by stage at diagnosis. Following a period of decline, hysterectomy‐corrected cervical cancer incidence increased 1.0%/year (95% CI = 0.1% to 4.5%) among Non‐Hispanic White women in low‐income counties. Particularly, a statistically significant 4.4%/year (95% CI = 1.7% to 7.5%) increase in distant‐stage cancer occurred in this group. Additionally, recent increases in cervical cancer mortality (1.1%/year [95% CI = −1.4% to 3.7%]) were observed among this group and Non‐Hispanic Black women in low‐income counties (2.9%/year [95% CI = −2.3% to 18.2%]), but trends were not statistically significant. Among Hispanic women in low‐income counties, distant‐stage cervical cancer incidence increased 1.5%/year (95% CI = −0.6% to 4.1%), albeit not statistically significant. The increasing incidence of distant‐stage cervical cancer and mortality in specific racial/ethnic groups suggests that the recent introduction of higher sensitivity screening tests may not explain increasing trends in low‐income counties. Our findings suggest that the observed rise in cervical cancer incidence may reflect disruptions along the screening and treatment continuum. Future research to further comprehend these trends and continued enhancements in prevention are crucial to combat rising cervical cancer incidence and mortality in low‐income counties in the United States.
