    AbstractThe screening program for cervical cancer in Sweden, recommends screening with HPV test primarily for women over 30 years, but at the first screening test that is performed after the age of 40, both HPV test and cytology is recommended, so-called co-testing. The aim of this study was to examine how many cases of HPV negative cervical dysplasia that were found in this age-group, to be able to estimate the value of adding a co-test in an HPV screening program. A retrospective study of all abnormal cytological samples found in the cytology based screening program in the age group 41-45 years during the years 2012-2016 in the Region of Örebro County was performed. Out of the 10,511 women included in the study, 468 had an abnormal cytology screening test and 255/468 were HPV negative. The vast majority of the HPV negative cases had a normal cytology test as first follow-up. Of cases with remaining cytological abnormality, only four cases had histologically confirmed high-grade cervical dysplasia (CIN2) and no cases of HPV negative adenocarcinoma in situ or invasive cancer were found. Conclusion: With adding a single co-test to a HPV-based screening program, only a few extra cases of high-grade cervical dysplasia were found and the clinical significance of these cases is unclear.Copyright © 2021 The Author(s).
