Cervical Cancer Mortality Similar in U.S. and Netherlands
(HealthDay News) – The cervical cancer screening program used by the Netherlands is as effective as the screening protocol used in the United States, producing similar cervical cancer mortality rates in spite of less screening, according to research published in the March issue of the Milbank Quarterly.
Dik Habbema, MD, of the Erasmus MC University Medical Center in Rotterdam, Netherlands, and colleagues used nationally representative data sources from the Netherlands and the United States to estimate the number of Pap smears performed since 1950 and the rate of cervical cancer mortality for each country.
Over the period studied, the researchers found that cervical cancer mortality rates were similar for both the United States and the Netherlands, despite the fact that three to four times more Pap smears were performed in the United States. In both countries, the five-year coverage rate was approximately 80%–90% for women aged 30–64 years. However, in the United States, coverage was much higher for women <30 years and >60 years, as the screening in the Netherlands is limited to those aged 30–60. These differences impacted the age-specific mortality trends.
"Cross-country studies like ours are natural experiments that can produce insights not easily obtained from other types of study," the authors write. "The cervical cancer screening system in the Netherlands seems to have been as effective as the US system but used much less screening."
