Summary
Brief summary (as posted)
While there is broad consensus that HR-HPV detection is the best available primary screening test, there is no agreement about the most efficient and reliable triage procedure for HR-HPV positive women. Transient HR-HPV infections are very common, and the vast majority of these infections spontaneously regress after a year or two. Only a small fraction of cases will lead to persistent infection responsible for cervical neoplasia. The FRIDA Study is a large, population-based study that was designed to evaluate the performance and cost-effectiveness of different triage strategies for hrHPV-positive women in Mexico.

Arms and outcomes
Arms (1)
- label
- Women aged 30-64 years old
- description
- Women aged 30 to 64 years who attend the Cervical Cancer Screening Program in 100 health centers in the state of Tlaxcala, Mexico
- interventionNames
- Other: HPV screening and triage tests
Primary outcomes (1)
- measure
- Histologically confirmed cervical intraepithelial neoplasia grade 2 or worse (CIN2+)
- timeFrame
- 36 months
- description
- All women will be colposcopically evaluated in order to rule out any clinically evident invasive cancer. In cases of invasive cancer, patients will be referred to onco-gynecology services immediately. Before biopsy collection, endocervical sampling is performed using an Endocervex Brush®. A minimum of four biopsies are collected, at least one per quadrant, from the more suspicious area on cervical transformation zone. Histological evaluation of all samples (biopsies and/or endocervical curettage samples) will be evaluated for final diagnosis and confirmation of CIN2+ cases by two pathologists according to Mexico's Cervical Cancer Screening Programme's guidelines. An external expert-pathologist, will resolve discrepancies and render a final decision.
