OBJECTIVE: To evaluate the association of three patho-gnomonic criteria, inner border, ridge sign, and rag sign with high-grade cervical intraepithelial neoplasia (CIN) using video exoscopy. METHODS: Retrospective evaluation of video recordings of 335 patients, referred for diagnostic colposcopy, who underwent cervical biopsies, and, if indicated loop excisions, was performed. The most severe histologic diagnosis was recorded. Sensitivity, specificity, positive, negative predictive value, and likelihood ratios for highgrade CIN were calculated. RESULTS: In 285 patients (85%), a single colposcopy directed biopsy was taken; 50 patients (15%) underwent two biopsies. One hundred sixty-two patients (48%) underwent subsequent magnification-guided loop excision. Sensitivity, specificity, positive predictive value, and negative predictive value of the inner border to detect high-grade CIN were 20%, 99%, 97.9%, and 34.8%, respectively. The positive likelihood ratio (LR+) was 20.3 and the negative likelihood ratio (LR2) was 0.81. Sensitivity, specificity, positive predictive value, and negative predictive value of the ridge sign to detect high-grade CIN were 52.5%, 96.4%, 96.8%, and 46.6%, respectively. The LR+ ratio was 13.2 and the LR-ratio was 0.49. Sensitivity, specificity, positive predictive value, and negative predictive value of the rag sign to detect high-grade CIN were 38.4%, 96%, 95.7%, and 40.2%, respectively. The LR+ ratio was 9.7 and the LR-ratio was 0.6. Only the ridge sign showed a correlation with young age. Presence of any two signs significantly increased the LR of the presence of high-grade CIN. CONCLUSION: The inner border, ridge sign, and the newly defined rag sign are objective, effective colposcopic signs and are significantly associated with high-grade CIN. © 2013 by The American College of Obstetricians and Gynecologists.

Abstract

OBJECTIVE: To evaluate the association of three patho-gnomonic criteria, inner border, ridge sign, and rag sign with high-grade cervical intraepithelial neoplasia (CIN) using video exoscopy. METHODS: Retrospective evaluation of video recordings of 335 patients, referred for diagnostic colposcopy, who underwent cervical biopsies, and, if indicated loop excisions, was performed. The most severe histologic diagnosis was recorded. Sensitivity, specificity, positive, negative predictive value, and likelihood ratios for highgrade CIN were calculated. RESULTS: In 285 patients (85%), a single colposcopy directed biopsy was taken; 50 patients (15%) underwent two biopsies. One hundred sixty-two patients (48%) underwent subsequent magnification-guided loop excision. Sensitivity, specificity, positive predictive value, and negative predictive value of the inner border to detect high-grade CIN were 20%, 99%, 97.9%, and 34.8%, respectively. The positive likelihood ratio (LR+) was 20.3 and the negative likelihood ratio (LR2) was 0.81. Sensitivity, specificity, positive predictive value, and negative predictive value of the ridge sign to detect high-grade CIN were 52.5%, 96.4%, 96.8%, and 46.6%, respectively. The LR+ ratio was 13.2 and the LR-ratio was 0.49. Sensitivity, specificity, positive predictive value, and negative predictive value of the rag sign to detect high-grade CIN were 38.4%, 96%, 95.7%, and 40.2%, respectively. The LR+ ratio was 9.7 and the LR-ratio was 0.6. Only the ridge sign showed a correlation with young age. Presence of any two signs significantly increased the LR of the presence of high-grade CIN.
