Cervical And Self-Sample In Screening Study

Summary

The proposed study seeks to compare the diagnostic performance of Human Papillomavirus (HPV) testing in self-collected samples via the Eve Medical self-collection system© (Eve) with standard physician-collected samples for the detection of cervical intraepithelial neoplasia grade 1 or worse (CIN1+) and cervical cancer among women referred for colposcopy. The performance of the Eve sample will also be compared with that of a second self-sample via a cobas® PCR Female swab.

Approximately 1000 adult women with an abnormal Pap test at the level of an atypical squamous cells of undetermined significance or worse squamous or glandular abnormality (i.e., ASCUS+) or an abnormal co-test (ASCUS+ and HPV-positive) result will be recruited over a period of 12 months via colposcopy clinics located at the Jewish General Hospital, St-Mary's Hospital, and the McGill University Health Centers (Royal Victoria Hospital).

Participating women will undergo three cervical or cervicovaginal sampling techniques: 1) self-sampling using the Eve Medical self-collection system©; 2) self-sampling using a cobas® PCR Female swab; and 3) physician-collected sampling. The participants will also fill in a questionnaire on their experience with the convenience and acceptability of the Eve system, relative to the other two sampling approaches. The decision as to which self-sample is to be collected first will be dependent on randomization

HPV testing will be done using the cobas® 4800 HPV Test. The liquid medium of within the cobas® PCR CELL Collection Media with the provider collected sample and the cobas® PCR media with the two self-collected samples will be used to suspend the cellular material prior to HPV testing. We have made collaborative arrangements with Dr. Marcel Behr, Chief of the Department of Clinical Microbiology at the McGill University Health Centre for the HPV genotyping work.

Histology-confirmed CIN1+ will form the study outcome or case definition. Sensitivity, specificity, and predictive values (along with their respective 95% confidence intervals) will be calculated for each sample type to evaluate the clinical performance of the various sampling techniques. We will use CIN1+ as definition of disease but analyses will also be performed for more stringent definitions, e.g. CIN2+ or CIN3/cancer.

Conditions

• Cervical Cancer
• Intraepithelial Neoplasia

Interventions

DEVICE

Eve Medical self-collection system©

The Eve collection system is a plastic device not much bigger than a tampon that is inserted in the vaginal cavity. A silicone brush is then swiped around the vagina to scrape a few vaginal cells for cervical cancer screening.

DEVICE

cobas® PCR Female swab self-sampling

Regular polyester swab for collection of vaginal cells.

PROCEDURE

Physician-collected sampling

Routine colposcopy sample collected by a physician.
