The present study assesses the results of cervical cancer (CC) screening over two 3-year periods (2008-2010 and 2011-2013) by comparing two screening tests [Papanicolaou (Pap) and human papillomavirus (HPV) tests] and two screening methods (organized and spontaneous). The study population includes women aged 25-64 years who underwent CC screening between 2008 and 2010 and/or 2011 and 2013, divided into those who responded to an invitation letter (organized screening) and those who spontaneously underwent testing at a public or private facility (non-programmed screening). Between 2008 and 2010, the response rates increased from 27.7% in 2008 to 44.5% in 2009 and 67.6% in 2010 (P<0.001). Women aged 25-34 years had the lowest response rate, whereas respondents were more frequent among women aged 35-44 and 45-54 years. Significant differences (P<0.001) were identified between organized and spontaneous screening test results with regard to diagnostic categories high-grade squamous intraepithelial lesion (50.5 vs. 49.5%), low-grade squamous intraepithelial lesion (42.8 vs. 57.2%) and undetermined lesion atypical glandular cells (AGC; 57.5 vs. 42.5%) or atypical squamous cells of undetermined significance (ASC-US; 54.2 vs. 45.8%). Compared with spontaneous screening, the organized programme resulted in a larger number of women screened for CC; it reduced the frequency of undetermined diagnoses (AGC, ASC-US), and identified a larger number of high-grade lesions.

Abstract

The present study assesses the results of cervical cancer (CC) screening over two 3-year periods (2008-2010 and 2011-2013) by comparing two screening tests [Papanicolaou (Pap) and human papillomavirus (HPV) tests] and two screening methods (organized and spontaneous). The study population includes women aged 25-64 years who underwent CC screening between 2008 and 2010 and/or 2011 and 2013, divided into those who responded to an invitation letter (organized screening) and those who spontaneously underwent testing at a public or private facility (non-programmed screening). Between 2008 and 2010, the response rates increased from 27.7% in 2008 to 44.5% in 2009 and 67.6% in 2010 (P<0.001). Women aged 25-34 years had the lowest response rate, whereas respondents were more frequent among women aged 35-44 and 45-54 years. Significant differences (P<0.001) were identified between organized and spontaneous screening test results with regard to diagnostic categories high-grade squamous intraepithelial lesion (50.5 vs. 49.5%), low-grade squamous intraepithelial lesion (42.8 vs. 57.2%) and undetermined lesion atypical glandular cells (AGC; 57.5 vs. 42.5%) or atypical squamous cells of undetermined significance (ASC-US; 54.2 vs. 45.8%). Compared with spontaneous screening, the organized programme resulted in a larger number of women screened for CC; it reduced the frequency of undetermined diagnoses (AGC, ASC-US), and identified a larger number of high-grade lesions.
