FRIDAY, March 11, 2022 (HealthDay News) — The incidence of human papillomavirus (HPV)-associated cancers is beginning to rise, with larger increases in the lowest-income counties and counties with high smoking prevalence, according to published research is listed in the April issue of JNCI Cancer Spectrum.
Yueh-Yun Lin of the UTHealth School of Public Health in Houston and colleagues used the Surveillance, Epidemiology, and End Results 21 database to identify HPV-associated cancers from 2000 to 2018 and the prevalence of smoking.
The researchers found that in the lowest-income counties, the incidence of anal and vulvar cancer in women and anal cancer incidence in men increased significantly, while the increases in the highest-income counties were slower (e.g., 0.8 percent in the districts with the lowest or highest income). The incidence of cervical cancer in recent years has plateaued (0.0 percent per year) in the highest-income counties and increased by 1.6 percent per year in the lowest-income counties. Significant increases in incidence were observed for counties with high smoking prevalence compared to their counterparts (e.g., anal cancer increased 4.4 versus 1.2 percent per year in men living in counties with the highest versus lowest smoking prevalence).
‘The decline in cervical cancer incidence has begun to be reversed, and in disadvantaged counties there have been marked increases in the incidence of anal, oropharyngeal and vulvar cancer,’ the authors write. “Targeted public health interventions are urgently needed to reduce growing inequalities.”
