Hypothesis
Can HPV typing in abnormal cervical smears predict the presence of high-grade cervical intraepithelial neoplasia (CIN II/III)?
Conclusion
High levels of HPV 16 in cervical smears are a strong predictor of high-grade lesions, while low levels are not helpful.
Supporting Evidence
- High levels of HPV 16 predicted CIN II/III in 93% of cases.
- 84% of CIN III lesions contained high levels of at least one HPV type.
- HPV testing was more predictive of high-grade lesions than cytology alone.
Takeaway
This study found that if a woman has a lot of HPV 16 in her cervical smear, she likely has a serious problem that needs immediate attention.
Methodology
The study involved HPV typing and quantitation using PCR on exfoliated cells from women referred for colposcopy due to abnormal smears.
Potential Biases
Potential bias due to the selection of women referred for colposcopy, which may not represent the general population.
Limitations
The study may have missed some low-grade diseases due to reliance on histology and colposcopy.
Participant Demographics
Mean age of participants was 32 years, with a mix of cytological and pathological subgroups.
