    Abstract
  •   Objective  To evaluate the clinical value of the R-way colposcopy diagnosis system in diagnosing cervical diseases.  Methods  From January 2018 to December 2018, amongst the patients who visited the colposcopy clinic of the First Affiliated Hospital of Bengbu Medical College, 380 patients with complete image and pathological follow-up results were selected. The R-way diagnosis system was used to analyse the images retrospectively and provide diagnosis results. Histopathological diagnosis was taken as the "gold standard" to compare the sensitivity, specificity, Youden index, and consistency test of the R-way diagnostic system and 2011 colposcopy diagnostic terms in the diagnosis of cervical lesions. We further calculated the area under the ROC curve and evaluated the clinical value of the R-way diagnostic system in diagnosing cervical diseases.  Results  The R-way diagnosis system had a sensitivity of 62.9%, a specificity of 100.0%, Youden index of 69.2%, and a concordance rate of 98.9% for diagnosing cervical cancer. The sensitivity for diagnosing high-grade squamous intraepithelial lesions (HSIL) was 84.9%, the specificity was 89.5%, the Youden index was 74.5%, and the concordance rate was 88.4%. The sensitivity for diagnosing low-grade squamous intraepithelial lesions (LSIL) was 76.1%, specificity was 79.0%, Youden index was 55.1%, and concordance was 78.2%. With the assumption that HSIL and above lesions were the positive group, LSIL and other lesions were the negative group. The sensitivity of the positive group of the R-way system and colposcopic terminology were 86.8% and 73.6%, respectively, the specificity were 90.5% and 90.9%, and the area under the ROC curve were 0.887 and 0.822.  Conclusion  The R-way diagnostic system is a simple, easy, stable and effective diagnostic system for objectively evaluating colposcopic images. It has high-potential clinical application and promotion value.
