AbstractBackground: Human papillomavirus (HPV) DNA test is more sensitive and can detect more high-grade cervical intraepithelial lesions than cytology test in cervical cancer screening. There are studies confirming HPV test being more effective in cervical cancer screening by detecting the persistence of HPV infection that could lead to cancer. However, the costs associated with a HPV test is higher than a cytology test. Moreover, HPV test is less specific which could subject more women to further triage tests or unnecessary invasive diagnostic procedures. Therefore healthcare costs could possibly increase if primary HPV screening is to be adopted. Study objective: The aim of the study is to systematically review the cost-effectiveness of primary HPV testing in cervical cancer screening Method: Electronic search was performed in three biomedical databases (PubMed, Medline, Cochrane Library) and one economic evaluation database to identify relevant studies. Studies were selected according to the explicit inclusion and exclusion criteria defined. Only those studies carried out in high-income countries were included so that result could be better applied to Hong Kong. Results: A total of 19 studies were included in this systematic review. Cytology-only method is generally not cost-effective. To be cost-effective, it has to be performed in a longer screening interval which would reduce not only the screening costs but also a reduction in the health outcomes. Among the different options in HPV-based primary screening, HPV testing with cytology triage is the most cost-effective strategy in many of the studies. Combined HPV/cytology co-screening could achieve the biggest health benefit but is also most costly. HPV-based screening is more cost-effective for those >30 years of age and is usually less cost-effective if applied to young women. From the result in sensitivity analysis, HPV-based screening is sensitive to an increase in the costs of the HPV test, a low HPV test sensitivity and a low screening compliance rate. Conclusion: Primary HPV screening is cost-effective and generally performs better than cytology screening. The result of this systematic review guides the future direction of developing an optimal cervical screening strategy in Hong Kong. Local context has to be considered when examining the cost-effectiveness of primary HPV testing for cervical screening. Good quality local epidemiological data on HPV infection and cervical cancer and screening would be required to aid future research on the application of HPV test for cervical cancer screening in Hong Kong.
