Is There Geographic Variation in Poland in the Distribution of Specific HPV Genotypes in Normal Cervical Epithelium, Dysplastic Lesions, and Cervical Cancers?

Cervical cancer remains a major public health challenge worldwide and in Poland, where mortality rates are among the highest in the European Union. Persistent infection with high-risk human papillomavirus (hrHPV), particularly genotype HPV16, plays a central role in cervical carcinogenesis. This study aimed to evaluate the regional variability of hrHPV prevalence and genotype distribution in Poland and to assess its potential implications for cervical cancer incidence and prevention strategies. A systematic literature review was conducted using PubMed, Scopus, and Google Scholar to identify studies published up to May 2025 reporting hrHPV prevalence and genotypes among Polish women. Eligible studies included population-based cohorts, women undergoing screening, and patients with cervical lesions or cancer. The analysis revealed substantial heterogeneity in hrHPV prevalence and genotype distribution across regions and study populations. Nationwide data indicate high overall HPV prevalence (up to 50.9%), with HPV16 consistently dominating, followed by HPV31, HPV51, HPV52, and HPV66. Regional differences were observed, including higher prevalence of HPV51 in southern Poland and HPV56 and HPV45 in central regions. Studies in women with abnormal cytology or cervical cancer showed markedly higher hrHPV prevalence (often >90%), with HPV16 predominating in high-grade lesions and invasive cancer. These findings confirm the dominant oncogenic role of HPV16 while highlighting significant regional variability in other hrHPV genotypes. Such differences may influence the effectiveness of screening and vaccination programs. Strengthening standardized, regionally stratified HPV surveillance is essential to optimize cervical cancer prevention and tailor public health interventions in Poland.
