New Evidence on the Impact of Cervical Cancer Screening and Treatment Using HPV DNA Tests, Visual Inspection or Cytology
- VIA-based programs can be key to establishing the necessary programmatic structures for cervical cancer prevention, including community education and sensitization, provider training and supervision, referral methods for higher-level care, methods to invite women to screening and monitoring systems to track screening coverage and follow-up rates. All of these structures are essential to success of an eventual HPV test-based program.
- VIA will be an important component of an HPV DNA test-based program, as it is used to triage women who should not receive cryotherapy due to large lesions or suspected cancer. Trained providers who can visualize the cervix and identify acetowhite areas accurately will be a core component of any future cervical cancer prevention program, including those using HPV testing or future molecular assays.
Finally, it is important to note that screening programs are complex, and all screening study results are impacted by a variety of factors, including underlying incidence of disease, overall capacity of the health system and access to trained providers, among others.
