Worldwide burden of cervical human papillomavirus (HPV) in women over 50 years with abnormal cytology: a systematic review and meta-analysis
Introduction More than half of global cervical cancer cases occur among women older than 50. However, global estimates regarding the human papillomavirus (HPV) prevalence among this population are lacking, especially for women with abnormal cytology. Therefore, we conducted a systematic review and m...

| description | Introduction More than half of global cervical cancer cases occur among women older than 50. However, global estimates regarding the human papillomavirus (HPV) prevalence among this population are lacking, especially for women with abnormal cytology. Therefore, we conducted a systematic review and meta-analysis to estimate the worldwide HPV prevalence in women aged 50 and older with abnormal cytology.Methods We searched PubMed, Scopus and Web of Science for quantitative studies reporting any or high-risk (HR)-HPV prevalence for women 50 years and older with abnormal cytology (atypical squamous cells of undetermined significance and higher). We extracted data on world region, subregion, cervical lesion type, recruitment setting, HPV test, year of study conduct and HPV prevalence from the included studies. We assessed the risk of bias of the included studies using a modified Newcastle-Ottawa scale. We estimated the pooled prevalence and 95% CIs of any-HPV and HR-HPV using random-effects models, considering the world regions. Additionally, we estimated the prevalence by HPV type, lesion type and age groups.Results Overall, 113 studies met the inclusion criteria, of which 104 were included in the meta-analysis. Among women aged 50 and older with abnormal cytology, the estimated global pooled prevalence of any-HPV from 53 studies, including 14 585 women, was 54.5% (95%CI, 46.0 to 62.8%), and the HR-HPV prevalence from 85 studies, covering 33 672 women, was 43.0% (95%CI, 36.6 to 49.5%). There was a higher HR-HPV prevalence among women with high-grade lesions and women living in the African continent. No major differences in HR-HPV prevalence between the age groups of women over 50 years were found. The most common single HPV types worldwide were 16 and 52, with pooled prevalence estimates of 12.0% (95%CI, 8.0% to 17.7%) and 8.4% (95%CI, 4.4% to 15.4%), respectively.Conclusion Our findings highlight the relevance of targeted screening interventions among women 50 years and older. To achieve the elimination of cervical cancer, age-inclusive screening strategies should be considered.PROSPERO registration number CRD42021241365. |
