Abstract
IntroductionTo 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 methodsRetrospective 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. ResultsOnly 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. ConclusionsOnly 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.
