Performance of alternative strategies for primary cervical cancer screening in sub-Saharan Africa: systematic review and meta-analysis of diagnostic test accuracy studies.

Bottom Line: Prevalence of CIN2+ did not vary by screening test and ranged from 2.3% (95% confidence interval 1.5% to 3.3%) in VILI studies to 4.9% (2.7% to 7.8%) in HPV testing studies.Pooled sensitivity and specificity were similar for HPV testing versus VIA (both P ≥ 0.23) and versus VILI (both P ≥ 0.16).Accuracy of VIA and VILI increased with sample size and time period.

Fig 2 Absolute sensitivity and specificity of VIA, VILI, and HPV testing for CIN2+ detection in sub-Saharan Africa. Diamond=95% confidence interval of the pooled measure computed with a bivariate random effects model. This figure includes only studies where the gold standard (colposcopy and colposcopy directed biopsies) was performed in all women of the study population (that is, GSA group). Heterogeneity across studies was assessed with Cochran’s Q test for each screening test (all P<0.05). DRC=Democratic Republic of Congo

Mentions: Figure 2 shows the variation of absolute sensitivity and specificity of VIA, VILI, and HPV testing in detecting CIN2+ in the GSA group. The pooled sensitivity for VIA in this group was 82.4% (95% confidence interval 76.3% to 87.3%) and ranged between 65.0% (40.8% to 84.6%) in Mali and 94.4% (90.6% to 97.0%) in Tanzania. The pooled specificity of VIA was 87.4% (77.1% to 93.4%), with the lowest value observed in Zimbabwe (64.1%, 61.9% to 66.2%) and the highest in Tanzania (98.2%, 98.0% to 98.5%).
