[The significance of HPV-DNA genotyping assays in the ASC].
OBJECTIVE
To disscuss different outcomes of ASC-UC and ASC-H, two subtypes of ASC, and the significance of HPV-DNA genotyping assays in these two subtypes.


METHODS
We reviewed and analyzed colposcopic and biopsy results of 1256 cases of ASC between Jan. 2005 to Dec. 2007, of which 580 cases have results of HPV-DNA genotyping assays.


RESULTS
In 1256 ASC cases, ASC-US and ASC-H cases account for 90.1% and 9.9% respectively, CIN2 and higher levels diagnosed via colposcopy and cervical biopsy are 8.5% and 24.2% respectively (P = 0.000). In ASC-US cases, the infection rate of HPV-DNA high risk types is 67.2%, there is statistic significance among different HPV-DNA results and biopsy pathology (P = 0.000). In ASC-H cases, the infection rate of HPV-DNA high risk types is 47.3%, there is no statistic significance among them (P = 0.054).


CONCLUSIONS
The clinical outcomes of ASC-US and ASC-H are different, we should distinguish and treat. HPV-DNA genotyping assay is available in ASC-US triage, but Colposcopy is proposed for all ASC-H patients.
