ABSTRACT
INTRODUCTION: To test for colposcopic differences between CIN2+ and non CIN2+ lesions of the "major changes" of the RIO 2011 nomenclature of the International Federation of Cervical Pathology (IFCPC). MATERIAL AND METHODS: Retrospective cohort analysis of colposcopic examinations of patients with histologically confirmed CIN2+ (n=99) and non CIN2+ (n=102) lesions during a four years period. MAIN OUTCOME MEASURES: leukoplakia, coarse mosaic and punctuation, dense acetowhitening, sharp boarders, ridge sign, atypical vessels. RESULTS: Only coarse punctuation (P≤0.001; OR 9.64; 95% CI 2.15-43.13), coarse mosaic (P≤0.001; OR 4.00; 95% CI 1.83-8.73) and dense acetowhitening (P≤0.05; OR 1.86; 95% CI 1.06-3.26) occurred more frequently in CIN2+ lesions which were confirmed as predictors by a regression analysis. CONCLUSIONS: Only coarse punctuation and coarse mosaic followed by dense acetowhitening as part of the "major changes" of the IFCPC Rio 2011 nomenclature achieve predictive values for CIN2+ lesions and should be therefore emphasized in colposcopy.
