About this study

Asbestos defines a group of naturally occurring mineral silicate fibers which are easily inhaled, resulting in a variety of diseases of the respiratory system including lung cancer and malignant mesothelioma. Despite some advances in treatment, there has been little impact on overall survival for both lung cancer and mesothelioma in the past 20 years in great part because patients usually present with disease at an advanced and incurable stage. This study aims to develop and implement a low-dose computed tomography (LDCT) screening approach for lung cancer and mesothelioma in asbestos-exposed workers in Alberta.

Read the detailed description

In Canada, lung cancer is the primary cause of cancer mortality above the next three culprits combined (breast, colon and prostate cancer). Cigarette smoking is the most important risk factor in the development of lung cancer. Another population of particular interest in Alberta involves workers with occupational exposure to asbestos as asbestos and tobacco exposure results in a synergistic effect on lung cancer risk. Mesothelioma is a rare cancer of the lining of the lung with poor prognosis of which 80% of cases are believed to be related to asbestos exposure.

Unfortunately, despite some advances in treatment, there has been little impact on overall survival for both lung cancer and mesothelioma in the past 20 years in great part because patients usually present with disease at an advanced and incurable stage. Additional strategies are desperately needed to reduce the morbidity and mortality associated with this disease.

The objectives of this study are to develop and implement a LDCT screening approach for lung cancer and mesothelioma in asbestos-exposed workers in Alberta; to determine participants' motivation and expectations associated with a screening program, their satisfaction with the program, and the psychosocial consequences of the screening program; to determine the accuracy of a lung cancer risk prediction model modified to include asbestos exposure; and to determine the 3-year clinical incidence of lung cancer in asbestos-exposed individuals interested in lung cancer screening but who do not meet minimal risk threshold.

The investigators will offer a combined lung cancer and mesothelioma screening program for 200 Alberta asbestos-exposed workers based on low-dose CT scanning.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Low-dose computed tomography Annual scan x3 and Low-dose computed tomography Baseline scan only in people with Lung Cancer and Mesothelioma, run by University of Calgary at 2 sites 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 3 inclusion and 7 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: stopped early, as of the sponsor's last update on 18 May 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Low enrollment through COVID pandemic). Results are not available in the source record.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in SF-12 quality of life score (time frame: Baseline vs. 14 days post receipt of screen results.). 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 18 May 2022.
