The sensitivity and specificity of the single screen method (TCT, HPV test, detection of the TERC and C-MYC genes, and VIA/VILI method) for CIN II was 80.9, 70.2, 72.3, 76.6, and 72.3%, as well as 98.0, 95.1, 96.3, 96.3, and 90.4%, respectively.
The study was designed to: (1) investigate the prevalence of high-risk human papillomavirus (HR- HPV) infection and cervical neoplasia; and (2) evaluate clinical performance of visual inspection with acetic acid/ Lugol's iodine (VIA /VILI), Pap smear, high-risk human papillomavirus (HR-HPV) DNA test for detecting cervical intraepithelial neoplasia grade 2 or worse (CIN2+) and (3) explore appropriate screening approach in rural areas of Shandong Province.
