OBJECTIVE: To examine the imprint of liquid-based technologies for cervicovaginal cytology on HIV-positive women, who are at high risk for cervical intraepithelial neoplasia. STUDY DESIGN: We performed a retrospective search of the cytopathology files of Johns Hopkins Hospital for the cervicovaginal cytology of HIV-positive women to examine the effect of liquid-based technology on this population. RESULTS: Significant intraepithelial lesions (SILs) (low grade SIL or greater) were identified in 24% of the conventional smears and 23% of the liquid-based cytology. Atypical squamous cells of undetermined significance (ASCUS)/atypical glandular cells of undetermined significance was diagnosed in 15% of the conventional smears and 9% of the liquid-based preparations (P = .02). In patients with ASCUS diagnoses and tissue follow-up within 7 months, significant SILs were identified in 29% with conventional smears and in 65% with liquid-based cytology. CONCLUSION: There was no statistically significant difference in the rate of SILs between conventional smears and liquid-based cervicovaginal preparations in HIV-positive women. The diagnosis of ASCUS on liquid-based cytology may have an increased likelihood of representing a significant SIL in comparison to conventional smears. For the high-risk, HIV-positive population, immediate colposcopy and biopsy may be warranted following ASCUS diagnoses on liquid-based cytology.
