HPV-triage with HC2 can be recommended to triage women with ASCUS because it has higher accuracy (significantly higher sensitivity, and similar specificity) than repeat cytology.


When triaging women with LSIL, an HC2 test yields a significantly higher sensitivity, but a significantly lower specificity, compared to a repeat cytology. Therefore, practice recommendations for management of women with LSIL should be balanced, taking local circumstances into account.
Comparison of the AMPLICOR human papillomavirus test and the hybrid capture 2 assay for detection of high-risk human papillomavirus in women with abnormal PAP smear.
Infection with human papillomavirus (HPV) is a necessary step in the progression to cervical cancer. Many methods for HPV testing are currently available, mostly developed to detect pools of HPV types. Hybrid Capture 2 (HC2) is one of the most widely used. A new PCR-based assay, the Roche AMPLICOR HPV test, has been recently developed. Both assays recognize a group of 13 HR HPV types contemporaneously. This study evaluated the performance of both methods for detecting high-grade cervical lesions as a part of management for abnormal PAP smears. The study population was composed of 213 women, all referred to colposcopy and histologic diagnosis following an abnormal PAP test. Biopsy-confirmed high-grade cervical intraepithelial neoplasia was used as a gold standard. Overall agreement was 84.9% with a kappa value of 0.6. When comparing the ability to detect moderate cervical intraepithelial neoplasia (CIN2+) and high-grade cervical intraepithelial neoplasia (CIN3+/cancer), AMPLICOR proved slightly more sensitive than HC2, a finding that is important when HPV testing is used in a triage of borderline smear results. Genotyping of discordant results showed a prevalence of LR-HPV types in HC2 positive/AMPLICOR negative samples, and a similar prevalence of HR- and LR-HPV types in AMPLICOR positive/HC2 negative samples. In conclusion, the study shows that the AMPLICOR assay is more sensitive than HC2, which makes it a valid alternative for routine clinical use.
