Anal HPV Tests in Screening for Cell Changes in the Anus in Patients With HIV
This clinical trial studies anal human papillomavirus (HPV) tests in screening for cell changes in the anus in patients with human immunodeficiency virus (HIV). Screening tests may help doctors find cancer cells early and plan better treatment for anal cancer. Completing multiple screening tests may help find the best method for detecting cell changes in the anus.

- Sensitivity of each of the methods of HSIL detection (anal cytology APTIMA, HC2 and OncoHealth HPVE6/E7 oncoprotein) [ Time Frame: Up to 2 years ] [ Designated as safety issue: No ]The binomial proportion and its 95% confidence interval will be used. Among patients who are high resolution anoscopy (HRA) positive for HSIL, McNemar's test will be used to compare routine anal cytology with each of the other methods of detection to determine if sensitivity in the diagnosis of HSIL is improved with the other methods. Positive and negative predictive values will be estimated for each method of detection.
- Specificity of each other methods of HSIL detection (anal cytology, APTIMA, HC2, and OncoHealth HPVE6/7) [ Time Frame: Up to 2 years ] [ Designated as safety issue: No ]Among patients who are HRA negative for HSIL, McNemar's test will be used to compare routine anal cytology with each of the other methods of HPV detection to improve specificity. Positive and negative predictive values will be estimated for each method of detection.
- Prevalence of HSIL [ Time Frame: Up to 2 years ] [ Designated as safety issue: No ]The prevalence of HSIL will be estimated as the proportion of women who are HRA positive for HSIL at entry and its 95% confidence interval. Logistic regression analysis will be used to evaluate the association of potential risk factors with diagnosis of HSIL.
- Incidence of HSIL among women who were HRA negative for HSIL at study entry [ Time Frame: Up to 2 years ] [ Designated as safety issue: No ]The Poisson rate and its 95% confidence interval will be estimated from the number of HSIL cases detected divided by the cumulative years of follow-up across these cases. Behavioral risk factors will be assessed by research staff administered surveys at each study visit. Logistic regression will be used to evaluate potential risk factors for incidence of HSIL.
- Incidence of anal HPV among women who were negative for anal HPV at study entry [ Time Frame: Up to 2 years ] [ Designated as safety issue: No ]The Poisson rate and its 95% confidence interval will be estimated from the number of anal HPV cases detected divided by the cumulative years of follow-up across these cases. Logistic regression will be used to evaluate potential risk factors for incidence of anal HPV.
- Acceptability of anal cancer screening among HIV-infected women based on survey responses regarding patient satisfaction and phone call surveys [ Time Frame: Up to 2 years ] [ Designated as safety issue: No ]Descriptive statistics will be used to characterize subjects' acceptability of undergoing anal screening with cytology/HPV and HRA throughout the study to evaluate changes in perceptions. Generalized estimating equations (GEE) will be used to assess acceptability over time adjusting for intrapatient variability. Acceptability will be correlated with clinical and behavioral risk factors, e.g., history of sexual assault, depression, anxiety, medication compliance, sexual behaviors using GEE methods.

Experimental: Screening (HSIL detection)
Patients undergo screening for the detection of HSIL using anal cytology, HPV hybrid capture 2, HPV mRNA assays, and OncoHealth HPVE6/E7 oncoprotein at baseline, at 6, 12, 18, and 24 months.

I. To determine the sensitivity and specificity of HPV testing using different methods of detection, including HPV Hybrid Capture 2 (HC2), HPV messenger ribonucleic acid (mRNA) assays (APTIMA) and OncoHealth HPV E6/E7 oncoprotein assay and whether they improve the screening performance of routine anal cytology for the detection of anal high-grade squamous intraepithelial lesions (HSIL) when measured against the gold standard, biopsy-proven HSIL.
II. To determine the prevalence and risk factors for prevalent HSIL in HIV-infected women.
III. To determine incidence and risk factors associated with anal HSIL and HPV over 2 years among HIV infected women undergoing semi-annual anal evaluations.
I. To evaluate the acceptability of anal cancer screening among HIV-infected women.
II. To collect data on quality of life and health care costs (including non-direct health care costs and time costs) for an economic evaluation of the cost-effectiveness of anal cancer screening strategies in HIV-positive women.
Patients undergo screening for the detection of HSIL using anal cytology, HPV hybrid capture 2, HPV mRNA assays, and OncoHealth HPVE6/E7 oncoprotein at baseline, at 12 and 24 months.
