Defining Optimal Triage Strategies for hrHPV Screen-Positive Women--An Evaluation of HPV 16/18 Genotyping, Cytology, and p16/Ki-67 Cytoimmunochemistry

Conclusions: All three single-test triage options, if positive, exceed the threshold of 20% risk at which colposcopy would be indicated. However, none of them conferred a post-test probability of CIN2+ <2%; which would permit routine recall. P16/Ki-67 cytoimmunochemistry on HPV16/18 negative women had a post-test probability of CIN2+ of 1.7% and 0.6% if also LBC negative. Impact: This is one of the few studies to directly compare the performance of triage strategies of hrHPV+ women, in isolation and combinations. It is the only study assessing triage strategies in women who test hrHPV+ in self-taken vaginal samples. A combined triage option that incorporated HPV 16/18 typing prior to p16/ki-67 cytoimmunochemistry in HPV 16/18–negative women yielded a post-test probability of CIN2+ of >20%, whereas women who tested negative had a probability of CIN2+ of <2%.
