Book excerpt: In this publication, recommendations for the Use of dual-stain cytology to triage women after a positive test for human papillomavirus (HPV) are presented. Dual-stain cytology can be used as a triage test in cervical “screen, triage and treat" algorithms for cancer prevention. It is performed on liquid-based cytology (LBC) slides (not on conventional Pap smears) to detect the presence of two proteins: p16 and Ki-67. Recommendation for the general population of women: In a screen, triage and treat approach using HPV Nucleic Acid Tests (NATs) as the primary screening test among the general population of women, WHO suggests using partial genotyping, colposcopy, VIA, cytology or dual-stain cytology to triage women after a positive HPV NATs result. When providing dual-stain cytology to triage women after a positive HPV NAT, WHO suggests: using samples collected by the health worker; and retesting with HPV NATs 24 months after a negative dual-stain cytology result. These are conditional recommendations based on low-certainty evidence for dual-stain cytology as a triage test. No recommendation was made for using dual-stain cytology to triage women living with HIV after a positive HPV DNA test, because evidence on the outcomes of using dual-stain cytology applicable to this population was minimal.
