Triage Strategies in Cervical Cancer Prevention (FRIDA)

July 27, 2015 updated by: Eduardo Cesar Lazcano Ponce, Instituto Nacional de Salud Publica, Mexico

Molecular Triage in Cervical Cancer Prevention: The Tlaxcala Study

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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The target population is over <100,000 women aged 30 to 64 years who attend the Cervical Cancer Screening Program in 100 health centers in the state of Tlaxcala, Mexico. All women will be evaluated to determine hrHPV infection using the Cobas® 4800 HPV test. Triage strategies will be performed as reflex tests in all hrHPV-positive participants: HPV-16/18/45 genotyping, detection of the E6 oncoprotein of HPV-16/18, cytology, and immunocytochemistry using p16INK4a/Ki67. Women with at least one positive triage test will be referred for colposcopy evaluation, where a minimum of four biopsies and an endocervical sample are systematically collected. Histological confirmation will be performed by a standardized panel of pathologists.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

30 years to 64 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

Study Population

This is a population-based study that includes all women aged 30 to 64 years living in the 32 municipalities in Tlaxcala covered by Sanitary Jurisdiction No. 1 of Tlaxcala Health Services

Description

Inclusion Criteria:

  • Women aged 30 to 64
  • Residents of the municipalities included in Sanitary Jurisdiction No. 1 of Tlaxcala.

Exclusion Criteria:

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Women aged 30-64 years old
Women aged 30 to 64 years who attend the Cervical Cancer Screening Program in 100 health centers in the state of Tlaxcala, Mexico
Other: HPV screening and triage tests
All cervical and/or vaginal specimens are tested for hrHPV using the Cobas® 4800 HPV test. Triage testing will be performed on all participants with a positive HR-HPV test declared consent at recruitment visit: HPV16/18 genotyping, Cobas® 4800 HPV test, HPV16/18/45 genotyping, BD OnclarityTM HPV Assay, OncoE6 Cervical Test, Liquid based cytology with Papanicolaou stain and p16INK4a/ Ki-67 immunostain.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Histologically confirmed cervical intraepithelial neoplasia grade 2 or worse (CIN2+)
Time Frame: 36 months
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.
