Prevalence of Human Papillomavirus and cervical lesions among women
older than 64 years and outside the Chinese cervical cancer screening
age in Guangzhou
Abstract
The prevalence of human papillomavirus (HPV) genotype and cervical
dysplasia in women older than 64 years, who are outside the Chinese
cervical cancer screening age, has not been extensively studied. Here we
conducted a retrospective analysis of women from a tertiary hospital in
Guangzhou, aiming to provide meaningful advice for cervical cancer
prevention and control in Guangzhou, China. In this study, the
age-specific prevalence of any HPV genotypes showed a U-shaped pattern,
and the second peak was observed among women >64 years,
which was 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 in 24
months among women > 64 years was 33.33%, which was higher
than that of women among <25 years age group (20.75%), and
25-64 years age group (20.46%). For HPV-positive women aged
>64 years, the proportion of cervical cancer (16.47%) was
obviously higher than that in women aged 25-64 years (2.41%) (
P<0.001). The infection of HPV 58 was the greatest risk
factor for the occurrence of HSIL+ (OR 3.556; 95% CI, 1.107-11.415;
P=0.032) in women aged >64 years, with HPV+/NILM. In
conclusion, the burden of HPV infection in women >64 years
is heavy in Guangzhou. Re-evaluate cervical cancer screening strategies
for women after age 64 is needed. And HPV 16/18/52/58 genotype model may
be an alternative triage strategy to discover HSIL+ among women aged
>64 years, with HPV+/NILM.
