RESUMO
OBJECTIVE: To establish the feasibility and acceptability of home-based HPV self-sampling among women who did not attend screening appointments in rural El Salvador. METHODS: In a cross-sectional study, data were collected from May 2015 to January 2016 among 60 women aged 30-59 years who were not pregnant, provided informed consent, had not been screened in 2 years, had no history of pre-cancer treatment, and did not attend a scheduled HPV screening. Participants completed questionnaires and received educational information before being given an opportunity to self-sample with the Hybrid Capture 2 High Risk HPV DNA Test. RESULTS: Self-sampling was accepted by 41 (68%) participants. Almost all women chose to self-sample because the process was easy (40/41, 98%), could be performed at home (40/41, 98%), and saved time (38/41, 93%), and because they felt less embarrassed (33/41, 80%). The most common reason for declining the test was not wanting to be screened (8/19, 42%). The prevalence of high-risk HPV types among women who accepted self-sampling was 17% (7/41). CONCLUSION: For most women, community-based self-sampling was an acceptable way to participate in a cervical cancer screening program. In low-resource countries, incorporating community-based self-sampling into screening programs might improve coverage of high-risk women.

OBJECTIVE: The present study assessed the adequacy and predictive performance of visual inspection with acetic acid (VIA) in women over the age of 50 years and compared the specificity and sensitivity of VIA with that of the conventional cytology. METHODS: In total, 588 Salvadoran women ages 50-79 underwent VIA, Pap smear, and cervical biopsy. VIA was considered adequate if the squamocolumnar junction was completely visible. A positive biopsy was defined as cervical intraepithelial neoplasia (CIN) 2 or worse. RESULTS: Age was negatively correlated with VIA adequacy (P=0.04). Nevertheless, the majority of women-even in the older age groups-had adequate examinations. The adequacy of VIA was positively correlated with gravida (P=0.01) and was higher in women who had been treated by cryotherapy (P=0.02). The rate of positive biopsies was unexpectedly low (n=6 [1%]) making it difficult to assess the predictive performance of VIA. In this small sample, the sensitivities of VIA (17%) and Pap (33%) were low; the high number of false negatives could not be fully explained by inadequacy of the examinations. CONCLUSIONS: Adequacy of VIA declined with age. However, the squamocolumnar junction was visible to the naked eye in the majority of women, indicating that they are good candidates for VIA.
