Diagnostic value of colposcopy in patients with cytology-negative and HR-HPV-positive cervical lesions
High-risk human papillomavirus (HR-HPV)-positive but cytology-negative cervical cancer screening results are not uncommon. This study aimed to investigate colposcopy's accuracy and diagnostic value in patients with cytology-negative HR-HPV-positive screening results. This retrospective study included patients with HR-HPV-positive cytology-negative screening results who underwent electronic colposcopy with acetic acid and multi-point cervical biopsy, HPV typing (24 HPV subtypes), and quantitative HPV detection. Among 229 patients, 130 had chronic cervicitis, and 99 had cervical lesions (CIN1, n = 37; CIN2/3, n = 55; invasive carcinoma, n = 7). Using colposcopy as a reference, the cervical cytology false-negative rate was 43.2% (99/229). Colposcopy was more accurate in patients with HR-HPV16/18 or high viral loads. Multivariable analyses showed HPV viral load and childbearing history were the independent factors affecting the accuracy of colposcopy (P < 0.05). Colposcopy in HR-HPV-positive cytology-negative patients has a moderate diagnostic accuracy. The type of cervical transformation zone and HPV viral load are independent factors affecting the accuracy of colposcopy-based diagnosis.
