About this study

Official title: Confocal Laser Endomicroscopy in Pleural Malignancies: A Comparison With Pathology

To date, the different biopsy methods, such as CT-guided pleural biopsy, mediastinal biopsy, endosonography and thoracoscopy have their limitations in diagnosing pleural malignancies, such as mesothelioma. Sampling errors frequently occur resulting in the common histological finding of 'non-specific pleuritic/fibrosis', which presents a great uncertainty for clinicians and patients. Confocal laser endomicroscopy (CLE) provides real-time imaging on a cellular level, however data of CLE in pleural malignancies are lacking.

Read the detailed description

Novel optical imaging techniques such as confocal laser endomicroscopy (CLE) have emerged in recent years as techniques that actually enable in vivo real-time microscopic analysis of malignancies of the GI-tract and lung cancer. Through recent advances the probe became small enough to fit through a biopsy needle and can be used during CT-guided and endosonographic guided biopsies (EUS-FNA). Patients with intra-thoracic malignancies often require invasive procedures such as bronchoscopy, thoracoscopy, mediastinoscopy, transthoracic needle aspiration or surgical exploration to obtain a diagnosis. Intra thoracic malignancies encompass lung cancers, thymomas and malignant pleural mesothelioma. These tumors often present with pleural thickening, unilateral pleural effusion, mediastinal enlargement or a peripheral located mass in the lungs. Tissue collection of the suspected pleural thickening is required to assess a diagnosis and differentiate between the tumor types, to classify and to stage in a proper manner. To date, the different biopsy methods, such as CT-guided pleural biopsy, mediastinal biopsy, endosonography and thoracoscopy have their limitations in diagnosing these malignancies. Sampling errors frequently occur resulting in the common histological finding of 'non-specific pleuritic/fibrosis', which presents a great uncertainty for clinicians and patients. Novel microscopic imaging techniques such as CLE are capable of real time imaging on a cellular level. Data of CLE in intra-thoracic malignancies are lacking.

Questions about this trial

What is this clinical trial studying?

An observational study of Pleural Malignant Mesothelioma and Thymoma, run by Academisch Medisch Centrum - Universiteit van Amsterdam (AMC-UvA) at 2 sites in Netherlands.

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 3 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: status not confirmed, as of the sponsor's last update on 21 Sep 2017. 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 Netherlands. 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?

Results are not available in the source record.

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

Contact L Wijmans, MD (+31205667924, l.wijmans@amc.uva.nl), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Technical feasibility: Number of successful procedures with evaluable CLE-imaging (time frame: cross sectional (1 day)). The study lists 3 primary outcomes in all. 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 21 Sep 2017; AzTrials last refreshed its copy on 31 Oct 2026.
