Human papillomavirus detection and typing in thin prep cervical cytologic specimens comparing the Digene Hybrid...

Area of Science:

• Gynecology
• Virology
• Molecular Diagnostics

Background:

• Cervical cancer screening relies on accurate human papillomavirus (HPV) DNA detection.
• Comparing HPV testing methods is crucial for optimizing diagnostic performance.

Purpose of the Study:

• To correlate cervical cytology results with HPV detection rates across three distinct assays.
• To evaluate the agreement between the Digene Hybrid Capture II Assay (HC), Roche Linear Array HPV Genotyping Assay (LA), and Kurabo GeneSquare Microarray (GS) for HPV detection.

Main Methods:

• Cervical cytologic specimens from 202 subjects were analyzed using HC, LA, and GS assays.
• Type-specific PCR was employed for HPV types 52, 33, 35, and 58 when indicated by the LA assay.
• Binomial proportions and kappa coefficients were calculated to assess inter-assay agreement.

Main Results:

• HPV detection rates increased with the severity of cytologic abnormalities across all tested assays.
• The LA and GS assays demonstrated higher HPV detection (both overall and oncogenic types) compared to the HC assay.
• The highest agreement in HPV detection was found between the LA and GS assays.

Conclusions:

• The Roche Linear Array and Kurabo GeneSquare Microarray assays show superior sensitivity for HPV DNA detection compared to the Digene Hybrid Capture II Assay.
• High concordance between LA and GS suggests their potential as reliable methods for HPV testing in cervical screening programs.
