Abstract
OBJECTIVE: To retrospectively analyse the incidence of high-grade squamous intraepithelial lesions (HSILs) and squamous cell carcinoma (SCC) in women of different ages with high-risk (HR) human papillomavirus (HPV) but with normal cytology test results stratified by age and HPV genotype. METHODS: In total, 1858 women with HR-HPV infection but with a normal smear who received a colposcopy and biopsy between 2015 and 2016 at our institution were included. The pathological results were retrospectively analysed after stratifying by age and HPV genotype. RESULTS: Among the 1858 cases, the HSIL% in women aged 21-29 years (10.54%) was significantly different from that in women aged 40-49 years (19.85%; P < 0.05), whereas there was no significant difference in the HSIL% among women aged 21-29 years and those in the other age groups (P > 0.05). In total, 295 cases had single HPV16 infection. The HSIL% in patients with HPV16/18 infection was >15%, and the 40-49-year age group had the highest percentage at 48.48%. For other HR-HPV infections, the HSIL and SCC incidence rate was 10.41%, and there was no significant difference among the age groups; thus, women with other types of viral infections, regardless of age, should be referred to colposcopy. CONCLUSIONS: Although HPV16 is the HPV with the highest risk, other HR-HPV infections can also cause a high percentage of HSILs and SCC in women with normal cytology. Therefore, it is necessary to refer HR-HPV-infected women aged ≥21 years for colposcopy in a timely manner to exclude potential cervical intraepithelial neoplasia and cervical cancer.
