Retrospective analysis of cervical cancer and precancerous lesions in patients with atypical squamous cells of undetermined significance in China

This study aims to investigate the prevalence of cervical intraepithelial neoplasia 1 or worse (CIN1+) and CIN3 or worse (CIN3+) in patients with ASCUS in China to provide insight into appropriate management for Chinese health care. In a retrospective cross-sectional study, patients who underwent liquid-based thin layer cytology and human papillomavirus (HPV) co-testing at the Peking Union Medical College Hospital between January 2014 and January 2017, and had ASCUS results on liquid-based thin layer cytology test and underwent follow-up and colposcopic biopsy were included. Age, HPV DNA test, and pathological outcomes were assessed. One hundred forty-four patients with ASCUS and positive HPV test results were included. In the 3-year follow-up, 23 (16.0%) patients had CIN1, 28 (19.4%) had CIN2, and 17 (11.8%) had CIN3 or carcinoma in situ. The risk of CIN3+ was significantly higher in those older than 60 years (42.8%, Pā€Š=ā€Š.005), whereas the CIN1+ prevalence displayed no significant difference between age groups. Both hybrid Capture II (HC II) value and cytopathological description of HPV infection showed no statistically significant correlation with CIN1+ or CIN3+. Patients with HPV-positive ASCUS who were older than 60 years had a significantly higher risk of CIN3+, and clinicians should pay more attention to them. Both HC II value and cytopathological description of HPV infection showed no significant correlation with CIN1+ or CIN3+.
