Cyto-histological correlation of ASC-H at Hospital Nacional Guillermo Almenara Irigoyen, January 2013 - July 2015

Abstract

Cervical cancer is the most prevalent neoplasm in women in our country. The Papanicolaou test is used as a screening test, and is reported using the Bethesda System. In this system, the ASC-H (atypical squamous cells – cannot exclude HSIL-high grade squamous epithelial lesions) category designates cases with atypical squamous cells, where the changes are suggestive of a high grade squamous intraepithelial lesion but insufficient for a definitive cytopathologic interpretation. It becomes important to determine the cyto-histological correlation in this group. Objective: To correlate cytopathologic results reported as ASC-H with histopathological diagnoses. Designs: Descriptive, cross sectional retrospective study. Material: Cervicovaginal cytology and histology. Method: We reviewed the cases with a cytologicalpathological study between January 2013 and July 2015 and with a histopathological study until a year later. The population and diagnoses were determined using the database. Histopathological diagnosis was considered as the gold standard. Main outcome measures: Cyto-histological correlation in ASC-H cases. Results: Out of the total of 53 716 cervical cytology studies performed during the study period, 119 were classified as ASC-H; 43 (0.07%) cases met the inclusion criteria. The age ranged between 22 and 70 years, with an average of 43.8 years; 42% of ASC-H cases were diagnosed as presenting CIN2 and CIN3 in the histopathological study. Conclusion: This study showed correlation between ASC-H results and high-grade intraepithelial lesions (CIN2 and CIN3), in line with findings in the literature.
