Trends in Cervical and Anal Cancer Incidence and Mortality in the United States
Objectives
This article describe trends in the incidence and mortality of cervical (CC) and anal (AC) cancers by race and neighborhood socioeconomic status.
Methods
The Surveillance, Epidemiology, and End Results (SEER) database was used to construct a cohort of CC and AC cases from 2006 to 2018. Incidence rates and survival were calculated by race and neighborhood socioeconomic status (nSES). Annual percent change (APC) in incidence was calculated using linear regression, and 5-year overall survival (OS) by the Kaplan-Meier method.
Results
Of the cases, 33,487 CC and 16,018 AC cases were identified. Women of low nSES were nearly 4 times more likely to be diagnosed with cervical cancer than those of high nSES. Cervical cancer incidence declined marginally in all groups except for low nSES women who are White (APC 0.0). Women who are Black had lower 5-year OS than their nSES counterparts of other races (most notably for Black women of low nSES 53% vs White 63%). Similarly, the low nSES AC cohort contained nearly 3 times the number of diagnoses as the high nSES cohort. AC incidence increased most in women who are White (APC 1.8 and 2.2 for low and high nSES) and men who are Black and low nSES (APC 3.3). Five-year OS was lowest for men who are Asian American and Pacific Islander (40% and 50% for low and high nSES, respectively).
Conclusions
These data suggest a strong correlation between nSES, race, and their interaction on the incidence and survival trends of HPV-related disease and highlight inconsistent effects between cervical and anal cancers.
