Atypical squamous cells, cannot exclude high grade intraepithelial lesion (ASC-H): does HPV matter?

The role of human papillomavirus (HPV) in cases diagnosed as atypical squamous cells, cannot exclude high squamous grade intraepithelial lesion (ASC-H) in cervical specimens is not well established. The objective of this study is to evaluate the role of HPV status in cases of ASC-H in a major cancer center. One hundred thirty-two patients with a diagnosis of ASC-H were identified over a 4-yr period in our institution.

Interobserver variability: comparison between liquid-based and conventional preparations in gynecologic cytology.

Background: Studies have shown that the ThinPrep Papanicolaou test (TP) increases the detection of epithelial cell abnormalities compared with the conventional preparation. Little is known about the interobserver variability of reporting gynecologic cytology results using the TP preparation and its comparison with results obtained using the conventional method.

Methods: To compare the interobserver variability between the TP method and the conventional method for reporting the diagnoses of gynecologic cytology, 20 pairs of conventional and TP slides (total, 40 slides) that were prepared from split samples were evaluated blindly by 19 cytotechnologists from three different laboratories.
