Abstract

Atypical squamous cells of undetermined significance (ASC-US) is a broad diagnostic category that could be attributed to human papillomavirus infection (HPV), malignant neoplasia and reactive conditions. We evaluated our institutional experience with ASC-US in women who are positive for high risk HPV (HRHPV+) by the Digene hybrid capture method from 2005-2009 to identify the risk of progression to squamous intraepithelial lesion (SIL) and cervical intraepithelial neoplasia (CIN) in association with age. We reviewed cytologic and follow-up surgical pathology reports for all specimens available. Progression was defined as a diagnosis of at least CINI on follow-up biopsy or resection or SIL on cytology. We identified 2613 cases and follow-up was available in 1839 (70.4%). Of these 74.2% had just one follow-up, 16.2% had a total of 2 follow-ups, 5.3% had a total of 3 follow-ups, and the remaining had as many as 6 follow-ups. Among the 1839 patients, 69.4% were age 30 or younger, 16.0% were between 31 to 40, 9.0% were between 41 to 50, and 5.6% were 51 or older. Among these, 25-30% progressed to dysplasia. The risk of progression varied by age (p=0.04) and was lowest among women between the ages of 41-50. Our findings highlight the importance of continued cytologic follow-up in women with HRHPV+ ASC-US in order to detect progression of disease, although the risk of progression is age dependent.
