Increasing and stabilizing incidence trends seen for several subpopulations; declines attenuated in SCC
THURSDAY, May 2, 2019 (HealthDay News) — Many populations have increasing or stabilized incidence trends in cervical adenocarcinoma (AC), according to a study published in the June issue of Preventive Medicine.
Farhad Islami, M.D., Ph.D., from the American Cancer Society in Atlanta, and colleagues examined contemporary trends in cervical squamous cell carcinoma (SCC) and AC incidence rates in the United States by age group, race/ethnicity, and stage at diagnosis for 1999 to 2015 after accounting for hysterectomy.
The researchers found that the decrease in overall SCC incidence continued in all racial/ethnic groups except among non-Hispanic whites, in whom rates stabilized in the 2010s, mainly due to stable trends among those aged <50 years and a slower decrease in those aged 50 to 59 years. Following the stable trend between 1999 and 2002, AC incidence rates increased among non-Hispanic whites during 2002 to 2015 (1.3 percent per year), mainly due to increases in those ages 40 to 49 and 50 to 59 years. In blacks and Hispanics, overall AC incidence rates decreased during 1999 to 2015; rates were stable in Asian/Pacific islanders. Among non-Hispanic whites, the rates of distant-stage cervical SCC and AC increased in several age groups, but rates were generally stable in nonwhites.
“Our findings have significant public health implications in view of the opportunity to reduce premature morbidity and mortality and societal cost associated with the disease in young women,” the authors write.
