Abstract

Objective: To analyse the correlation between the colposcopic parameters of Grade 1 and Grade 2 abnormal transformation zone (ANTZ G1 – ANTZ G2) and histological examination of the cone. Materials and Methods: A retrospective analysis of medical records of 600 women who underwent colposcopy and conisation (large loop excision of the transformation zone - LLETZ) between January 1, 2009 and July 31, 2012. The correlation between colposcopic and histological parameters was analysed using the Spearman nonparametric test. Results: In ANTZG1 there was no correlation (r= - 0.03; p = 0.55); in ANTZG2 however, a low degree of correlation (r = 0.21; p = 0.03) was found. Sensitivity, specificity, and positive and negative predictive values of an ANTZ G2 colposcopic picture were 33.45% (confidence interval [CI] 95% 28.0% to 39.2%), 95.48% (CI 95% 92.5% to 97.5%), 87.4% (CI 95% 79.7% to 92.9%), and 60.5% (CI 95% 56% to 64.9%), respectively. Conclusions: The decisive factor in the diagnosis of the cervical oncologic pathologies is the histological examination of the cone, and not the colposcopy which should be seen as a “guiding” investigation in predicting conisation and application of the most appropriate treatment.
