Background:
To report quantitative and qualitative results on cervical cancer human papillomavirus (HPV)-based screening and treatment algorithms, with/out triage with visual inspection after acetic acid (VIA), followed by ablative treatment (AT).
Methods:
Women 30 to 54 years old from Durban, South Africa were recruited, regardless of human immunodeficiency virus (HIV) status, randomized into one of two study arms and screened for HPV. VIA triage arm: HPV-positive women were triaged using VIA, biopsied and received AT if VIA positive and eligible; no triage arm: eligible HPV-positive women received AT. Women ineligible for AT were referred to colposcopy. Women were asked about side effects immediately and 1 week after AT. Retention to screening and treatment algorithms was compared between arms.
Results:
A total of 350 women [275 HIV-uninfected and 75 women living with HIV, (WLWH)] were allocated to receive HPV testing with VIA triage (n = 175) or no triage (n = 175). HPV prevalence was 28% [95% confidence interval (CI) = 23-33]; WLWH: 52% (95% CI = 40-64) versus HIV-uninfected: 21% (95% CI = 17-27; P < 0.05). Among women who underwent VIA triage with histologic diagnosis, 3/17 were VIA negative with cervical intraepithelial neoplasia (CIN)2+; 14/18 were VIA positive with
Conclusions:
This pilot demonstrated the feasibility of implementing screening and treatment algorithms, including performing triage and treatment in one visit; however, VIA triage did not reduce overtreatment and missed some precancerous lesions.
Impact:
This study reports on implementation feasibility of two World Health Organization screening and treatment algorithms (with/out VIA triage). Although the retention to screening and treatment algorithms was high in both arms, the question of how best triaging HPV-positive women deserves further consideration, particularly for WLWH.
