About this trial

The PRIORITY study is a prospective, multicenter observational study designed to evaluate an integrated diagnostic model combining extended molecular self-sampling and digital colposcopy supported by telemedicine for the prioritization of women at risk of cervical cancer.

The study aims to assess the diagnostic performance, concordance, and clinical utility of this integrated approach in real-world settings, as well as its impact on diagnostic timeliness and patient navigation across different levels of care.

Participants will undergo standard-of-care evaluation, and data will be collected on molecular test results, colposcopic findings, diagnostic outcomes, and time intervals within the care pathway. No interventions are assigned as part of the study protocol.

The findings are expected to inform scalable strategies to improve early detection and optimize diagnostic pathways for cervical cancer, particularly in settings with structural and geographic barriers to timely care.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Women aged 30 to 65 years

Eligible for cervical cancer screening according to national guidelines

Able and willing to provide informed consent

Able to perform self-sampling or attend clinical evaluation if required

Disqualifiers

Previous diagnosis of cervical cancer

History of total hysterectomy (removal of the cervix)

Current pregnancy if it precludes study procedures according to clinical judgment

Any medical or social condition that, in the opinion of the investigators, would interfere with participation or follow-up

Trial population

Women aged 30 to 65 years participating in cervical cancer screening programs in participating centers, including both urban and underserved populations. The study aims to reflect real-world conditions, including variability in access to care, geographic barriers, and healthcare system navigation.

Trial outcomes

Primary outcomes

1

Diagnostic accuracy of the integrated molecular and digital model for detection of CIN2+

Sensitivity, specificity, positive predictive value, and negative predictive value of the combined strategy including extended molecular self-sampling, clinician-collected sampling, and digital colposcopy for detecting histologically confirmed cervical intraepithelial neoplasia grade 2 or worse (CIN2+). Measure reported: sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV).

Time frame
Up to 6 months

Secondary outcomes

1

Concordance between self-collected and clinician-collected samples for high-risk HPV and extended molecular panel detection

Agreement between vaginal self-sampling and clinician-collected cervical samples for detection of high-risk HPV genotypes and extended molecular findings, assessed using Cohen's kappa and percent agreement. Measure reported: Cohen's kappa coefficient and percent agreement.

Time frame
Baseline
2

Prevalence of sexually transmitted infections and vaginal dysbiosis markers detected by extended molecular screening

Prevalence of sexually transmitted infections and vaginal dysbiosis markers detected through the extended molecular panel, including Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, Trichomonas vaginalis, bacterial vaginosis-associated markers, Candida species, and genital ulcer pathogens. Measure reported: Prevalence (%) of sexually transmitted infections and vaginal dysbiosis markers detected through extended molecular screening.

Time frame
Baseline
3

Prevalence ratio of high-risk HPV positivity in participants with sexually transmitted infections detected by extended molecular screening

Prevalence ratio of high-risk HPV positivity among participants with sexually transmitted infections detected using the extended molecular screening panel. High-risk HPV positivity will be defined as the proportion (%) of participants with a positive validated molecular HPV test. Measure reported: Prevalence ratio (PR) with 95% confidence intervals.

Time frame
Up to 6 months
4

Odds ratio for histologically confirmed CIN2+ in participants with sexually transmitted infections detected by extended molecular screening

Odds ratio for histologically confirmed cervical intraepithelial neoplasia grade 2 or worse (CIN2+) among participants with sexually transmitted infections detected using the extended molecular screening panel. CIN2+ will be defined as the proportion (%) of participants with histologically confirmed cervical intraepithelial neoplasia grade 2 or worse. Measure reported: Odds ratio (OR) with 95% confidence intervals.

Time frame
Up to 6 months

Other outcomes

1

Participant-Reported Acceptability Score Using the Self-Sampling and Telemedicine Diagnostic Pathway Acceptability Questionnaire

Participant-reported acceptability will be assessed using the investigator-developed Self-Sampling and Telemedicine Diagnostic Pathway Acceptability Questionnaire, a structured 5-item questionnaire evaluating ease of self-sampling, confidence in performing the procedure, understanding of instructions, comfort with digital colposcopy, and satisfaction with telemedicine-supported follow-up. Each item is scored on a 5-point Likert scale from 1 to 5. A composite score will be calculated by summing all item responses. Scores range from 5 to 25 points, with higher scores indicating greater acceptability. Measure reported: Composite acceptability score (range 5-25 points; higher scores indicate greater acceptability).

Time frame
Up to 6 months
2

Direct transportation costs associated with the diagnostic pathway

Participant-reported transportation expenses associated with screening, diagnostic evaluation, referral visits, and follow-up care will be assessed using an investigator-developed healthcare utilization and cost questionnaire. Total transportation costs will be calculated as the cumulative sum of all transportation-related expenses incurred throughout the diagnostic pathway. Measure reported: Total transportation cost in Chilean pesos (CLP).

Time frame
Up to 6 months
3

Productive Activity Days Lost Associated With the Diagnostic Pathway

Number of participant-reported productive activity days lost throughout the diagnostic pathway, assessed as a single cumulative count variable. Measure reported: Total number of productive activity days lost.

Time frame
Up to 6 months
4

Indirect non-medical expenses associated with the diagnostic pathway

Participant-reported indirect non-medical expenses incurred during the diagnostic process will be assessed using an investigator-developed healthcare utilization and cost questionnaire. Total indirect non-medical expenses will be calculated as the cumulative sum of eligible participant-reported expenses. Measure reported: Total indirect non-medical expenses in Chilean pesos (CLP).

Time frame
Up to 6 months
