This study compares different screening approaches to detect abnormal cell growth on the cervix that could be an early sign of cervical cancer. The lesions are caused by an infection of human papillomavirus, also called HPV. Using new methods to detect HPV may help doctors find ways to improve cervical cancer screening for women living with human immunodeficiency virus (HIV) in the Dominican Republic and in other countries.
OUTLINE:
Participants participate in three annual interviews and clinical exams that last approximately 2 hours. Study participants provide blood, urine, and swab samples from the cervix, anus, and vagina and receive a pelvic exam. Any positive results are followed up in the study clinic.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Screening (biospecimen collection, cytology, interview) | Experimental | Participants participate in an interview and clinical exam, lasting approximately 2 hours. Participants undergo vaginal self-sampling, cervical provider-sampling, and collection of blood and urine samples. Participants also undergo a pelvic exam. After first interview and clinical exam at enrollment, participants have two subsequent study visits over a 2 year period. |

| Measure | Description | Time Frame |
|---|---|---|
| Detection of cervical precancerous lesions (CIN2+) by cytology vs HPV restricted genotyping | Compare performance characteristics of two screening strategies. Comparison between dichotomous tests will be summarized by: (i) the true positive rate (TPR) and (ii) the false positive rate (FPR). | At baseline |

| Measure | Description | Time Frame |
|---|---|---|
| Detection of CIN2+ is improved by cervical imaging with automated visual evaluation that uses a machine learning algorithm vs colposcopy | Post hoc evaluation not impacting treatment decision comparing colposcopy to image score by Cohen's kappa using a scale of normal, precancer+ and greyzone/low grade using a coordinated scale | At baseline |

After publication of original data, data and specimens may be shared upon request with other investigators at academic or nonprofit institutions in a limited data set, as defined under HIPAA. The final dataset and specimens will be stripped of identifiers prior to release for sharing.
One month after publication of the final report in manuscript form to a peer-reviewed journal.
Investigators requesting access to data and specimens must sign a data-sharing agreement that provides for: (1) a commitment to using the data or specimens only for research purposes and not to identify any individual participant; (2) a commitment to securing the data using appropriate computer technology; and (3) not sharing the data or specimens with third parties. We reserve the right to limit data provided to outside investigators. We will not share data if we believe there is a possibility of deductive disclosure of subjects with unusual characteristics.

| Assess overall burden of HPV disease |
Prevalence of non-cervical visible lesions, histological confirmation of non-cervix lesions (at the vulva, vagina, and peri-anal region), and hrHPV testing status at the vagina and anal canal |
| At baseline |
| Detection of cervical precancerous lesions (CIN3) by cytology vs HPV restricted genotyping | Compare performance characteristics of two screening strategies. Comparison between dichotomous tests will be summarized by: (i) the true positive rate (TPR) and (ii) the false positive rate (FPR). | At baseline |
| Cross-sectional diagnostic accuracy of triage by dual staining among hrHPV positive WLWH to detect CIN2+ | Estimate the diagnostic accuracy parameters (TPR, FPR, positive predictive value or PPV, negative predictive value or NPV) and their approximate 95% confidence intervals for the p16/Ki-67 dual staining triage strategy for WLWH who tested positive for restricted hrHPV genotyping at Month 0. Will also assess and compare the accuracy parameters (TPR/FPR) of the dual staining method as it applies to hrHPV16 positive WLWH versus those who are positive for other types of hrHPV in two-sample (unpaired) comparisons of proportions (two-sample proportion tests). | At baseline |
| Diagnostic accuracy of dual staining triage among hrHPV positive WLWH to detect CIN2+ by specimen collected and reading approach | Calculate (i) the Cohen's kappa and (ii) the concordance correlation coefficient to calculate agreement between the two methods. Use the McNemar test to compare the overall agreement between them. | At baseline |
| Diagnostic accuracy of hrHPV genotyping to detect CIN2+ among WLWH by vaginal vs cervical sampling | Calculate (i) the Cohen's kappa and (ii) the concordance correlation coefficient to calculate agreement between the two methods. Use the McNemar test to compare the overall agreement between them. | At baseline |
| CIN2+ Incidence | Estimate the cumulative incidence of newly detected CIN2+ over 2 years among women negative at previous time points. | At 12 and 24 months |
| Detection of repeat CIN2+ | Calculate the proportion positive a second time for CIN2+ at Month 12 or 24. | At 12 and 24 months |
