About this study

Official title: Diagnosis of Early Barrett's Neoplasia and Esophageal Squamous Cell Neoplasia by Electrical Impedance Spectroscopy in Human Tissue

Detection of early esophageal cancer in surrounding normal tissue can be challenging even for experienced examiners. The early detection is essential to determine the following treatment. Early stages of esophageal cancers can be treated by endoscopic resection whereas advanced neoplasia might lead to an Operation of the esophagus. Diagnosis is made usually by biopsies of suspicious lesions or untargeted quadrant biopsies. The electrical properties in inflammatory tissue and cancer can be sensed by electrical bioimpedance technique.

The aim of this study is to compare the impedance probe with the histological result and to investigate the feasibility of the new technique in detection of esophageal cancer.

Detection of early esophageal cancer in surrounding normal tissue can be challenging even for experienced examiners. The early detection is essential to determine the following treatment. Early stages of esophageal cancers can be treated by endoscopic resection (ER) whereas advanced neoplasia might lead to esophagectomy. Diagnosis is made usually by biopsies of suspicious lesions or untargeted quadrant biopsies. The electrical properties in inflammatory tissue and dysplasia can be sensed by electrical bioimpedance technique. The aim of this study is to compare the impedance probe with the histological result and to investigate the feasibility of the new technique in detection of esophageal cancer.

What participants receive

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

  • impedanceDevice

    After endoscopic resection of early esophageal cancer, the tissue will be measured by an impedance probe between 10Hz-1000000Hz, 20mV. 8 gold electrodes have been integrated to the probe. The impedance will be measured in different ways between the elctrodes. There will be 10 measurements in total for each specimen.

Questions about this trial

What is this clinical trial studying?

A study testing impedance in people with Cancer of Esophagus, run by Sana Klinikum Offenbach at 1 site in Germany.

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 1 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: finished, as of the sponsor's last update on 17 Jan 2023. 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 Germany. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

impedance (time frame: 10 min). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04046601, which also lists 1 linked publication.

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 17 Jan 2023.
