Overview

The main purpose of this study is to explore the accuracy and clinical value of fluorescent photoelectric cervical lesion image detector as a screening and shunt tool for cervical lesions through a multi-center, large-sample real-world study with histopathology as the gold standard. The secondary purpose of the study was to verify the coincidence of the fluorescent photoelectric cervical lesion image detector with traditional colposcopic chemical staining. This study is expected to include 20,000 participants with definite histological results, and compare the specificity and sensitivity, negative predictive value and positive predictive value of three cervical lesion screening methods, such as fluorescent photoelectric cervical lesion image detector, HPV nucleic acid detection and cytology detection. The advantages and disadvantages of fluorescent photoelectric cervical disease image detector, HPV nucleic acid detection and cytology examination were analyzed, and their application scenarios were provided to provide evidence-based medical support for the establishment of comprehensive prevention and treatment system of cervical cancer suitable for China's national conditions.

Conditions

Uterine Cervical Cancer High Grade Squamous Intraepithelial Lesions Low Grade Squamous Intraepithelial Lesions

Interventions

Detection of Cervical Lesions by Fluorescence Photoelectric ImageDIAGNOSTIC_TEST

The enrolled patients underwent fluorescence photoelectric cervical lesion image detection, followed by colposcopy and biopsy to obtain histopathological results. The results of fluorescence photoelectric image detection were compared with histopathological results, and at the same time compared with HPV and TCT results at the time of enrollment.

Outcomes

Primary Outcomes

Accuracy of tissue lesion screening based on photoelectric detection

The sensitivity, specificity, positive predictive value and negative predictive value of fluorescence photoelectric cervix lesion image detector were calculated by using CIN 2 + as the gold standard determined by histopathology, and compared with those of HPV and TCT.

Time frame: The data collection time for each subject is approximately 7 days, starting from the day of each subject's enrollment and ending when the pathology report of the cervical tissue biopsy under colposcopy is issued.
