OBJECTIVES: To synthesize the results of cost-effectiveness studies of different triage tests in comparison to repeat cytology for women with atypical squamous cells of undetermined significance (ASC-US) or low-grade squamous intraepithelial lesions (LSIL) results.
METHODS: Electronic databases (Medline/PubMed, Lilacs, Embase, The Cochrane Library, Scopus, Web of Science, Scielo, The NHS Economic Evaluation Database, Econlit, and CEA Registry) were searched for cost-effectiveness or cost-utility publications. Per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, two independent reviewers selected eligible publications based on the selection criteria and performed data extraction. Methodological quality was assessed using the Quality of Health Economic Studies tool.
RESULTS: Five cost-effectiveness analyses were included comparing HPV testing, immediate colposcopy, and liquid-based cytology with HPV testing reflex to repeat cytology. The main outcome adopted was cervical intraepithelial neoplasia level 2 or higher (CIN2+) cases detected. In pairwise comparisons, HPV testing was more frequently observed as the most cost-effective strategy. Incremental cost-effectiveness ratios were very sensitive to costs of test kit variation and accuracy estimates with some sensitivity analysis scenarios showing immediate colposcopy more cost-effective than HPV testing depending on the tests' unitary costs and effectiveness.
CONCLUSIONS: This systematic review of economic evidence corroborates clinical evidence showing cytology is the least effective, although less costly, triage strategy. Cytology-based triage programs need to be updated to offer timely treatment to women diagnosed with ASC-US/LSIL and better resource allocation.
