Early detection is a key to reducing cervical cancer related mortality. Cervical cancer typically is preceded by preinvasive changes known as Cervical Intraepithelial lesion (CIN) II-III.

Objective The aim of the study is to determine the prevalence of CIN II-III in VIA positive result.

Methodology This is retrospective cross-sectional study conducted at a tertiary government hospital outpatient clinic from January 2017 to May 2019. 373 asymptomatic Filipino women, ages 20–65 years old were included in the study. All underwent cervical cancer screening using VIA. Women who had VIA positive results underwent colposcopically guided cervical punch biopsy.

Results Among 373 patients, there were 97 (26.01%) who had a positive VIA result. Of these positive VIA women, nine had CIN II-III, and five patients with squamous cell carcinoma.

Conclusion The prevalence of CIN II-III among women with positive VIA was estimated at 9.28% (95% CI 4.3–16.88), while those with squamous cell carcinoma was at 5.15% (95% CI 1.69 – 11.62%).
