Association of human papillomavirus 16 and 18 with ovarian cancer risk: Insights from a meta‑analysis.

Ovarian cancer (OC) presents a global health challenge, with well-documented genetic aspects. However, to the best of our knowledge, the role of human papillomavirus (HPV) types 16 and 18 in OC remains unclear. The present meta-analysis assessed the prevalence of HPV in OC across 43 studies and included a comparative meta-analysis of 19 case-control studies to determine the association of HPV with OC risk. Subgroup analyses were performed based on geographic regions and histopathological types to explore heterogeneity, and publication bias was evaluated using funnel plots and statistical tests of asymmetry. The pooled prevalence of HPV was found to be 10% (95% CI, 5-18) and 7% (95% CI, 3-15) specifically for HPV 16/18. Case-control studies indicated an odds ratio (OR) of 4.92 (95% CI, 1.96-12.53) for HPV 16/18, with higher pooled prevalence rates of 17% for all HPV genotypes and 13% for HPV 16/18. Notably, Asian countries exhibited the highest HPV prevalence and OR in OC. These findings support the involvement of HPV, particularly HPV 16 and 18, in increasing the risk of OC, emphasizing the need for further research to confirm these associations and explore potential mechanisms.
