Methods: We evaluated p16INK4a/Ki-67 dual-stain cytology in a screening population in Thika district, Kenya and compared it to high-risk human papillomavirus (HR-HPV) DNA testing and visual inspection by acetic acid (VIA) and Lugol’s iodine (VILI). Results: Valid results for all tests could be obtained in 477 women. 20.9 % (100/477) were tested positive for HR-HPV DNA, 3.1 % (15/477) had positive VIA/VILI and 8.2 % (39/477) positive p16INK4a/Ki-67 cytology. Of 22 women that showed up for colposcopy and biopsy, 6 women were diagnosed with CIN3 and two with CIN2. All women with CIN2/3 were negative in VIA/VILI screening and positive by HR-HPV DNA testing. But HPV was also positive in 91.7 % (11/12) of women with normal histology. p16INK4a/Ki-67 cytology was positive in all 6 women with CIN3, in one of the two CIN2 and in only 8.3 % (1/12) of women with normal histology. Conclusions: p16INK4a/Ki-67 cytology is an interesting test for further studies in developing countries, since our findings point to a lower fraction of false positive test results using p16INK4a/Ki-67 cytology compared to HPV DNA testing in a Kenyan screening population. VIA/VILI missed all histology-proven CIN2/3. date: 2015 publisher: BioMed Central id_scheme: DOI ppn_swb: 1656056224 own_urn: urn:nbn:de:bsz:16-heidok-193864 language: eng bibsort: WANGARINGUP16INK4AKI2015 full_text_status: public publication: Infectious agents and cancer volume: 10 number: 25 place_of_pub: London pagerange: 1-6 issn: 1750-9378 citation: Wangari Ngugi, Caroline ; Schmidt, Dietmar ; Wanyoro, Karanja ; Boga, Hamadi ; Wanzala, Peter ; Muigai, Anne ; Mbithi, John ; von Knebel-Doeberitz, Magnus ; Reuschenbach, Miriam (2015) p16INK4a/Ki-67 dual stain cytology for cervical cancer screening in Thika district, Kenya.
