INTRODUCTION: The prevalence of human papillomavirus (HPV)16/18 in cervical cancer may decrease with age. This study aimed to describe the HPV genotype distribution in Danish women aged 55 years or older with cervical cancer. MATERIAL AND METHODS: In this cross-sectional study we identified 153 cases of cervical cancer diagnosed at Aarhus University Hospital, Denmark (1990-2012) and Copenhagen University Hospital Herlev, Denmark (2007-2012). All women had surgery to treat the disease. HPV genotyping was performed on cervical cancer tissue using the INNO LiPA HPV genotyping extra (Fujirebio, Belgium) at the Department of Pathology, Aarhus University Hospital, Denmark. The main outcome was to estimate the age-specific prevalence of high-risk HPV genotypes included in the bivalent, the quadrivalent, and the nonavalent vaccine. RESULTS: Of 121 cases of cervical cancer included in this study, 113 were HPV-positive (93.4%). Although HPV16 and 18 were the most common genotypes overall, the prevalence of HPV16/18 decreased significantly from 78.1% in women aged 55-59 years to 45.5% in women aged 75 or older (p
