Malignant Progression of Anal Intra-epithelial Neoplasia in a Cohort of Patients
France1,000 participantsStarted 2013-08
Plain-language summary
Evaluation of the 3-years anal carcinoma (AC) incidence in patient with anal AIN3 lesions, and factors associated with this AC. A retrospective cohort study will be conducted (2000-2013) followed by a prospective cohort study (starting in 2013) with new diagnoses of anal AIN3 lesion. The main outcome is histology proven AC. The 3-years incidence rate of AC will be calculated. Factors associated with AC will be estimated using a multivariate Cox regression model.

Inclusion Criteria:
To be included in the cohort, patients have to:
\- have an anal AIN3 (including Bowen's disease) diagnosed by histology (screening population, post-operative discovery…)
* Aposteriori for patients with a history of anal AIN3 complicated or not by an anal cancer. These cases will be identified from data bases of anatomopathology laboratories in hospitals since January 1st 2000.
* At the diagnostic for the new anal AIN3 Units care involved in the study are those involved in the follow-up of patients with anal pathologies en France, especially anal cancer. Samples are analyzed by the laboratories of anatomopathology of the hospitals where the patients are diagnosed. These points make the histological data bases reliable and allow clearly identifying cases of anal ain3 retrospectively since 2000.
Taking in account the number and quality of the units care involved in the study and the way cases are identified, we think our recruitment will be exhaustive in France, to limit selection bias.
\- Patient's non opposition to study
Exclusion Criteria:
* history of anal carcinoma without any history of anal AIN3 lesion
* impossible follow-up for the duration of the study (3 years or more)
* patient aged under 18
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
