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

Area of Science:

• Gynecologic pathology
• Oncology
• Virology

Background:

• The role of human papillomavirus (HPV) in atypical squamous cells, cannot exclude high squamous intraepithelial lesion (ASC-H) cervical diagnoses remains unclear.
• Accurate risk stratification for ASC-H cervical cytology is crucial for patient management.

Purpose of the Study:

• To evaluate the diagnostic utility of HPV status in cervical specimens with an ASC-H diagnosis.
• To determine if HPV testing can enhance the positive predictive value (PPV) of ASC-H for high-grade squamous intraepithelial lesions (HSIL).

Main Methods:

• Retrospective review of 132 patients diagnosed with ASC-H over a 4-year period.
• Analysis of high-risk HPV (HR-HPV) status in 44 of these cases.
• Correlation of HPV status with biopsy follow-up results to determine the PPV for HSIL.

Main Results:

• The overall positive predictive value (PPV) of ASC-H for high-grade squamous intraepithelial lesions (HSIL) was 32%.
• In cases of ASC-H with associated HR-HPV, the PPV for HSIL increased to 42%.
• This increase in PPV was statistically significant (P = 0.003).

Conclusions:

• HPV testing appears to be a valuable tool for improving the positive predictive value of ASC-H cervical cytology.
• Integrating HPV testing into the management of ASC-H cases may aid in more accurate detection of high-grade cervical lesions.
