Análise da correlação entre exames diagnósticos de lesões precursoras de câncer de colo de útero

Abstract

Objective: To investigate whether the prevalence of pre-malignant lesions for cervical cancer in oncotic cytology and colposcopy exams, to compare and correlate the results of both. Methods: Quantitative, exploratory, descriptive and cross-sectional study, performed at the Lower Genital Tract Pathology outpatient clinic of the Hospital Universitário Lauro Wanderley (HULW), João Pessoa-PB, from March 2017 to December 2020. The sample corresponds to the sector book records, including those that presented all the results properly recorded. The variables were categorized separately and evaluated using the SPSS software through frequency and proportion analyzes, using the Shapiro-Wilk, Pearson's Chi-square tests, Kappa index and Spearman's nonparametric correlation test to compare the results of the two exams. Results: 3,413 patients were registered, with 2617 who met the selection criteria. In oncotic cytology, the prevalence was of the category “no changes” with 83.2%. For colposcopy, 50.5% exams were obtained classified in “Normal Colposcopies”, 36% in “Altered Colposcopies”; and 13.6% in “Unsatisfactory Colposcopies”. The median age was 40 years, with a SD of 12.221. Pearson's chi-square test was performed with 250.920 (p≤0.05); the Kappa index with the result of 0.069 (p≤0.05); Spearman's nonparametric correlation with +0.255 (p≤0.05). Conclusion: It was concluded about the individual importance of each of the exams for the detection of pre-malignant lesions, even though the correlation between both has not been satisfactory and the importance of their performance and proper registration has been reinforced.
