OBJECTIVE: To compare the AutoCyte Prep® system (Burlington, North Carolina) with conventional cervical cytology in a university medical center laboratory. STUDY DESIGN: Split-sample conventional and AutoCyte Preps® were examined for 2,156 cases. Same-patient conventional and Prep® slides were submitted to separate cytotechnologists blindly. The results were compared on review by a cytopathologist. The Prep® slides were subsequently scanned on the AutoCyte Screen® automated interactive system, with manual review of the flagged cases. The results were compared with anatomic pathology follow-up when available. RESULTS: Of the 158 squamous intraepithelial lesions (SILs) found by both methods, 78% were found by AutoCyte Prep®, while 59% were found by conventional smear (P <.01). Among the discordant cases, thin-layer slides revealed 88% more LSIL lesions (P< .05), a comparable number of high grade SIL lesions and a single case of adenocarcinoma that was ambiguous on the conventional slide. The addition of AutoCyte® assisted primary screening demonstrated a net benefit, recovering additional cases referenced as atypical glandular cells of undetermined significance and as high grade SIL. CONCLUSION: The AutoCyte Prep® system affords excellent cellular presentations and superior sensitivity for SILs when compared to the conventional technique. The use of AutoCyte Screen® for primary screening demonstrated performance equivalent to manual screening, with a significant improvement in sensitivity when measured against biopsy results.
