| Sumario: | Background: The SelfCerv Self-Collection Cervical Health Screening Kit (Ilex Medical Ltd., Johannesburg, South Africa) is an applicator tampon designed for self-collection of vaginal samples for the detection of human papillomavirus (HPV) deoxyribonucleic acid (DNA) and E6/E7 messenger ribonucleic acid (mRNA). The study aimed to evaluate the performance of the SelfCerv applicator tampon for the detection of hr-HPV for cervical cancer screening, and further to investigate women’s experiences and preferences regarding self-sampling. Methods: Vaginal samples were collected from 527 gynecology clinic attendees aged ≥18 years at a tertiary hospital in Gauteng Province, South Africa. Self-samples were collected using the SelfCerv kit, followed by endocervical samples collected by a healthcare professional using Cervex-Brush<sup>®</sup> Combi. Participants completed a self-administered questionnaire on self-sampling experiences and preferences. Both samples were tested for 14 high-risk (hr) HPV types and E6/E7 mRNA using the Abbott RealTime HR-HPV and Aptima HR-HPV mRNA assays, respectively. Results: The overall agreement for hr-HPV typing between 527 paired samples was good (87.1%; κ =0.74) with high sensitivity (86.2%) and specificity (88.0%). HPV-16 (96.4%; κ = 0.83) had higher agreement rate than HPV-18 (96.8%; κ = 0.72) and the other 12 hr-HPVs (86.5%; κ = 0.72). Two hundred and eighty-five (285) sample pairs tested for E6/E7 mRNA showed fair agreement (70.2%; κ= 0.34). Furthermore, self-sampling was reported as comfortable (90.5%) and painless (86.7%), with 88.4% of women preferring self-collection. Conclusions: Self-collected samples had good agreement with the healthcare professional-collected samples for the detection of hr-HPV DNA and the procedure was highly preferred by women. Self-sampling using SelfCerv can be used as an alternative to healthcare professional sampling in clinic-based routine cervical cancer screening. |
