Abstract

Objectives. To determine interrater variability in classifying cervical biopsies from women with human immunodeficiency virus (HIV). Materials and methods. Cervical biopsies performed on women participating in the Women's Interagency HIV Study (WIHS) were read at the six participating sites. A 10% random sample was retrieved and reviewed using standardized terminology by pathologists with a special interest in gynecologic pathology. Results were compared with kappa values and Mantel-Haentzel tests. Results. Biopsies from 288 HIV-seropositive and 24 HIV-seronegative women were reviewed. The weighted kappa value of 0.67 indicated moderate to strong agreement between original and review diagnoses, with a range of 0.54 to 0.84 across sites. No cancers were identified. Significantly more specimens showing cervical intraepithelial neoplasia (CIN) grade 2 or 3 were identified by review pathologists (p =.02). CIN2 or CIN3 was graded less severely by local pathologists in 18 (51%) of 35 cases, all from HIV-seropositive women. Local pathologists' diagnoses of CIN2 or CIN3 were downgraded by reviewers in 4 of 21 cases (19%). Discrepancies were more common among women with lower CD4 lymphocyte counts. Conclusions. Although discrepancies occur, interrater correlation in the interpretation of cervical biopsies from women with HIV is moderate to strong.
