Visual inspection with acetic acid screening for cervical cancer among women receiving anti-retroviral therapy for human immunodeficiency virus infection in northern Tanzania.

AIM: To evaluate visual inspection with acetic acid (VIA) screening for cervical cancer among human immunodeficiency virus (HIV)-positive patients in an East African community. METHODS: During a July 2018 cervical cancer screen-and-treat in Mwanza, Tanzania, participants were offered free cervical VIA screening, cryotherapy when indicated, and HIV testing. Acetowhite lesions and/or abnormal vascularity were designated VIA positive in accordance with current guidelines. The association between VIA results and HIV status was compared using Chi-square and Fisher exact tests. RESULTS: Eight hundred and twenty-four of 921 consented participants underwent VIA screening and 25.0% (n = 206) were VIA positive. VIA-positive nonpregnant women (n = 147) received cryotherapy and 15 (1.8%) with cancerous-appearing lesions were referred to Bugando Hospital. Sixty-six women were HIV-positive and included 25 diagnosed with HIV at the cervical cancer VIA screening and 41 with a prior diagnosis of HIV who were receiving antiretroviral therapy (ART) at the time of cervical cancer VIA screening. Sixty-four of these 66 patients, were screened with VIA. HIV infection was not associated with VIA findings. Abnormal VIA positive screening was observed in 20.3% (n = 13) of HIV-positive patients and in 24.4% (n = 145) of HIV-negative patients (p = 0.508). A nonsignificant trend of higher VIA positive screens among newly diagnosed HIV patients of 26.1% (n = 6) versus patients with preexisting HIV on ART of 17.1% (n = 7) was observed (p = 0.580). CONCLUSION: The unexpected lack of correlation between HIV infection and VIA positivity in a community with access to ART warrants additional research regarding the previously described role of ART in attenuating HPV-mediated neoplasia.

Implementation of human papillomavirus video education for women participating in mass cervical cancer screening in Tanzania.

BACKGROUND: Because the global disease burden of cervical cancer is greatest in Africa, the World Health Organization has endorsed visual inspection with acetic acid screening with cryotherapy triage for the screen-and-treat approach. With the lowest doctor-to-patient ratio worldwide (1:50,000), Tanzania has nearly 10,000 new cases of cervical cancer and 7000 deaths annually. OBJECTIVE: We report on the feasibility of visual inspection with acetic acid in the severely resource-limited Mwanza district and on the impact of intervening education on baseline human papillomavirus and cervical cancer knowledge. STUDY DESIGN: Two 5-day free visual inspection with acetic acid (VIA) clinics in urban Buzuruga and rural Sangabuye on the shores of Lake Victoria were approved by our university institutional review board and local Tanzanian health authorities. Participants completed a demographic survey and a 6-question (1 point per question) multiple choice test written in Kiswahili to assess baseline knowledge. A 15-minute educational video in Kiswahili (MedicalAidFilms: Understanding screening, treatment, and prevention of cervical cancer) was followed by repeated assessment using the same test, visual inspection with acetic acid screening, and optional HIV testing. Pre- and postvideo scores and change of score were analyzed via t test, analysis of variance, and multivariate regression. Significance was considered at P<.05. RESULTS: From July 2, 2018 to July 6, 2018, 825 women were screened, and 207 women (25.1%) were VIA positive (VIA+). One hundred forty-seven VIA+ nonpregnant women received same-day cryotherapy. Seven hundred sixty women participated in an educational intervention-61.6% of whom were from an urban site and 38.2% from a rural site. The mean age was 36.4 (standard deviation, 11.1). Primary languages were Kiswahili (62.2%) and Kisukuma (30.6%). Literacy was approximately 73%, and average education level was equivalent to the seventh grade (United States). Less than 20% of urban and rural women reported access to healthcare providers. Mean score of the participants before watching the video was 2.22 (standard deviation, 1.76) and was not different between VIA+ and VIA negative groups. Mean score of the participants after watching the video was 3.86 (standard deviation, 1.78). Postvideo scores significantly improved regardless of age group, clinic site, primary language, education level, literacy, or access to healthcare provider (P<.0001). Change of score after watching the video was significantly greater in participants from urban areas (1.99±2.07) than in those from rural areas (1.07±1.95) (P<.0001). Multivariate analysis identified urban site as an independent factor in change of score (P=.0211). CONCLUSION: Visual inspection with acetic acid screening for cervical cancer is feasible and accepted in northern Tanzania. Short video-based educational intervention improved baseline knowledge on the consequences of human papillomavirus infection in the studied populations. The impact was greater in the urban setting than in the rural setting.
