Trial summary

Almost half of all women will develop an HPV infection in their lifetime. While most infections are naturally asymptomatic or cleared by the immune system, some persist and can lead to the development of cervical, vulvar, or anal lesions and eventually cancer. Read more about this study

About this study

Almost half of all women will develop an HPV infection in their lifetime. While most infections are naturally asymptomatic or cleared by the immune system, some persist and can lead to the development of cervical, vulvar, or anal lesions and eventually cancer. Screening regimens for these lesions are currently only in place for the cervix through regular Pap tests. These Pap tests usually involve an examination of the vulva -however, no screening procedures exist for anal cancer for women. Several studies have suggested that women with existing gynecological lesions are more likely to develop anal lesions and anal cancer. Here the investigators propose a multi-center study which seeks to screen for and treat anal cancer in women over the age of 40 with vulvar lesions and a stable immune system. The investigators will achieve this through performing anal Pap smears on eligible women and conducting High Resolution Anoscopy (HRA) and appropriate treatment procedures on those with abnormal anal cells. With enough evidence, there may be an indication to establish regular anal cancer screening measures in this potentially underserved population.

Hypothesis: The investigators hypothesize that at least 40% of women with vulvar cancer or VIN2/3 will have abnormal anal cytology. 35% of the population will be hrHPV DNA positive and 11% will additionally have AIN2/3. This prospective study may lay the groundwork for routine anal screening regimens in Ontario and help shift health policy to treat this population.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Screening anal Pap smear - No high-resolution anoscopyProcedure or surgery

    75% of patients with negative cytology on their anal Pap smear will not receive high-resolution anoscopy

  • Screening anal Pap smear - High-resolution anoscopyProcedure or surgery

    25% of patients with negative cytology on their anal Pap smear will receive high-resolution anoscopy. All patients with positive (abnormal) cytology on their anal Pap smear will receive high-resolution anoscopy.

Screening anal Pap Smear - Negative (75%)OtherAll patients will receive an anal Pap test. 75% of patients with a negative anal Pap will complete study with no further intervention.
Receives: Procedure: Screening anal Pap smear - No high-resolution anoscopy
Screening anal Pap Smear - Negative (25%)OtherAll patients will receive an anal Pap test. Remaining 25% of patients will proceed to high-resolution anoscopy (HRA) clinic to assess the negative predictive rate of HRA.
Receives: Procedure: Screening anal Pap smear - High-resolution anoscopy
Screening anal Pap Smear - PositiveOtherAll patients will receive an anal Pap test. Any patient with abnormal cytology on their Pap test will be referred to HRA clinic for management. This includes potential biopsy and treatment.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Prevalence of abnormal anal cytology and hrHPV DNA in women with VIN 2/3 or vulvar cancer

    Measured: 6 months to 1 year

Secondary outcomes (2)
  1. Prevalence of AIN in women with VIN 2/3 or vulvar cancer

    Measured: 6 months to 1 year

  2. Assess t he correlation between abnormal anal cytology, hrHPV DNA, and AIN

    Measured: 6 months to 1 year

Questions about this trial

What is this clinical trial studying?

A study testing Screening anal Pap smear - No high-resolution anoscopy and Screening anal Pap smear - High-resolution anoscopy in people with Vulvar Cancer and Cervical Cancer, run by Dr. Danielle Vicus at 1 site in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 16 May 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Nithla Mohanathas, BSc (4164805000 ext. 85838, nithla.mohanathas@sunnybrook.ca), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Prevalence of abnormal anal cytology and hrHPV DNA in women with VIN 2/3 or vulvar cancer (time frame: 6 months to 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 May 2025.
