Prevalence of human papillomavirus and cervical lesions among elderly women: an unignored challenge to cervical cancer prevention.

The prevalence of human papillomavirus (HPV) genotype and cervical neoplasia in women older than 64 years, who are outside the age demographic of cervical cancer screening in China, has been under-researched. This study conducts a retrospective analysis of women from a tertiary hospital in Guangzhou, with the aim to offer valuable insights for cervical cancer prevention and control in elderly women. The study incorporated 876 women, all aged 64 and above. In this age bracket, the prevalence rate of any HPV genotype was found to be 19.27%. The top six HR HPV genotypes were HPV 16, HPV 52, HPV 58, HPV 31, HPV 33, and HPV 18. The persistence rate of any HPV type over a 24-month period in this age group was as high as 33.33%. Among women over 64, around 16.47% of HPV-positive patients were diagnosed with cervical cancer. HPV 58 infection was the most substantial risk factor for histological CIN2+ (OR 3.556; 95% CI, 1.107-11.415;  = 0.032) in women over 64 years of age with HPV-positive/NILM status. In conclusion, the burden of HPV infection is significant among women over 64 years in Guangzhou. Re-evaluation of cervical cancer screening strategies for women after the age of 64 is imperative. Moreover, the HPV 16/18/52/58 genotype model could serve as an alternative triage approach to identify histological CIN2+ among elderly women with HPV-positive/NILM status.
