About this study

Official title: DNA Methylation Biomarker in Biliary Brush Sample for Diagnosis of Cholangiocarcinoma in Patients With Bile Duct Stricture

DNA methylation biomarker for diagnosis of cholangiocarcinoma in patients with bile duct stricture has high sensitivity and specificity compared with cytology from the brush specimens

Read the detailed description

The methylation of HOXA1, NEUROG1 were used to determine cholangiocarcinoma from brushed biliary samples. However, the sensitivity and specificity of this test for cholangiocarcinoma is still required.

Being tested
Control, Cholangiocarcinoma
Medical subject headings
Cholangiocarcinoma

What participants receive

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

  • ControlDiagnostic test

    Brushed biliary samples from a known case of benign biliary stricture were sent for DNA Methylation Biomarker test and cell cytology

  • CholangiocarcinomaDiagnostic test

    Brushed biliary samples from a known case of cholangiocarcinoma were sent for DNA Methylation Biomarker test and cell cytology

What is being measured

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

  1. The methylation of HOXA1, NEUROG1 were determined in brushed biliary samples from patients with CCAs compared to those of nonmalignant bile duct stricture

    Methylation index of biliary brush samples were analyzed.

    Measured: 2 weeks

Secondary outcomes (2)
  1. Sensitivity, specificity of DNA methylation for diagnosis of cholangiocarcinoma

    Diagnostic accuracy of methylation index for diagnosis of cholangiocarcinoma was analyzed.

    Measured: 2 weeks

  2. To compared sensitivity, specificity of DNA methylation with routine cytology of biliary brushed samples

    Diagnostic accuracy of methylation index was compared to routine brush cytology.

    Measured: 2 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Cholangiocarcinoma in people with Cholangiocarcinoma and Biliary Stricture, run by Mahidol University at 1 site in Thailand.

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 2 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 29 Sep 2020. 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 Thailand. 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. Some participants in this study may receive a placebo. 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?

The methylation of HOXA1, NEUROG1 were determined in brushed biliary samples from patients with CCAs compared to those of nonmalignant bile duct stricture (time frame: 2 weeks). 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 NCT04568512, 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 29 Sep 2020.
