Probabilidad de displasia severa (NIC II/III) en pacientes con resultado citológico ASC-H (células escamosas atípicas que no puede excluir una lesión intraepitelial) y ASC-US (células escamosas atípicas de significancia indeterminada)(Universidad Peruana de Ciencias Aplicadas (UPC), 2016-02-08)Background The Bethesda system is used to classify Pap smear results. Some of the results are ASC-US (atypical squamous cells of undetermined significance) and ASC- H cells (atypical squamous cells cannot exclude intraepithelial lesion). It has been found an association between these results with cervical neoplasia; however they have not been well studied in Peru. Objectives To calculate the probability of severe dysplasia in situ or squamous cell cancer in women with cytology results of ASC-H and ASC-US. Methods An observational, cross-sectional study was carried out in a reference higher complexity health establishment in Lima, Peru (4th level), from 2012 to 2013, in which 1060 data of patients was analyzed. Bivariate and multiple binomial logistic regression analysis were performed. Chi square test was used and p-value < 0.05 was considered as significant. Results 1060 Pap smears were evaluated. Mean age was 46,4 (SD: 13,2) years and 64,9% were under 50 years old. ASC-US prevalence was 3,45% and ASC-H 0,32%. Out of 175 biopsies, 22,9% had moderate to severe dysplasia, carcinoma in situ or squamous carcinoma. There was an association between ASC-H finding and the presence of moderate/severe dysplasia (CIN 2/3), carcinoma in situ and squamous cell carcinoma (PR=2,39; CI(95%):1,49-3,81). Conclusion Given the association found, women with ASC-H findings should be further and thoroughly studied in order to look for moderate/severe dysplasia (CIN2/3) or squamous cell carcinoma.Acceso abierto
