ATHENA trial results in the ASC-US population

≥CIN2

Absolute risk of ≥CIN2 stratified by hrHPV status in the ATHENA ASC-US population3

Absolute Risk of ≥CIN2 Stratified by hrHPV Status in the ATHENA ASC-US Population

The cobas® HPV Test identifies women with highest risk of cervical cancer.

  • The NHSCSP guidelines recommends referral for colposcopy for women with ASC-US /borderline cytology and low-grade dyskaryosis who are hrHPV positive either at triage or test of cure/post treatment testing.1 
  • The ASCCP supports referral for colposcopy for women with ASC-US who are hrHPV positive.2
  • The cobas® HPV Test helps you follow the guidelines by providing pooled hrHPV results.
 

 

 
  • The cobas® HPV Test also provides individual HPV 16 results to help you identify those women at highest risk who may need more intensive postcolposcopic follow-up.
 
Conclusion: Individual detection of HPV 16 in women with ASC-US cytology identifies those women who are at the highest risk of cervical precancer.3

Uses of triage

Stratification of ASC-US with the cobas® HPV Test identifies women who are hrHPV positive or HPV 16 positive separately3

Uses for ASC-US Triage

Conclusion: Women with ASC-US cytology who are HPV 16+ could benefit from intensive follow-up in the case of an unsatisfactory colposcopy result.3

Validation of the cobas® HPV Test

cobas® HPV Test and Hybrid Capture 2 (hc2)* in the ASC-US population for detection of ≥CIN24

The performance of the cobas® HPV Test is comparable to that of the prior standard of testing for pooled high-risk HPV, while adding the benefit of providing genotyping results for the highest-risk genotypes, HPV 16 and 18.

Clinical implications for the cobas® HPV Test from ATHENA in the ASC-US population

  • Comparable performance to the prior standard of testing in pooled hrHPV testing
  • Significantly improves upon other commercially available HPV tests by individually identifying HPV 16 and 18 while simultaneously detecting 12 other hrHPV genotypes as a pooled result
  • The absolute risk of ≥CIN2 was 31.5% among women who were HPV 16 positive3
  • Pooled hrHPV negative women were at low risk of ≥CIN23
  • Women who were HPV 16 positive were more than twice as likely to have ≥CIN2 than those women who were pooled hrHPV positive3
