    Abstract
    Cervical cancer screening is currently based on high-risk human papillomavirus (HR-HPV) molecular testing, Pap cytology testing, and histologic evaluation of cervical biopsies. As primary HPV screening for cervical cancer becomes widely used, some of the recommended screening guidelines propose colposcopy and biopsies following positivity for HPV16/18 without cytologic triage. In such instances, a biopsy would be the only tissue sample available for informing further management. The use of additional histologic levels on cervical biopsies is commonly employed to achieve a diagnosis, although no set criteria for when to obtain additional levels exist. In this study, we evaluated the value of additional sections in cervical biopsy and endocervical curetting, as well as clinical and histologic features that should be considered when ordering additional levels. Additional levels were obtained for the following scenarios: benign mucosa with Pap discrepancy (HSIL or ASC-H interpretation), size discrepancy with the gross description, suspicious atypia for a high-grade lesion, and long-standing high-risk HPV infection. A change in diagnosis was observed in 21.4% of the cases, with an upgrade to a high-grade squamous intraepithelial lesion (CIN2–3) in 12.1% of cases. An initial impression of atypia significantly correlated with both a change in diagnosis and an upgrade to CIN2–3. In the era of primary HPV screening, when evaluating tissue samples following positive HPV test, small, atypical foci should be followed by additional levels. We recommend six (6) initial levels on all cervical biopsies, particularly if there is no loss of tissue between the levels, to ensure an accurate interpretation. This will be crucial in the timely and accurate identification of HPV-related intraepithelial lesions and proper subsequent management.
