About this study

The aim of this study is to develop a protocol for detection of circulating tumor DNA (ctDNA) in plasma of patients with early stages of gastric cancer.

Read the detailed description

Gastric cancer (GC) is the fifth most common cancer worldwide and the third leading cause of cancer deaths. Earlier detection of GC can dramatically increases the five-year survival rate up to > 90%. The current endoscopy and tissue biopsy remain excessively expensive for middle-income nations, in addition to being fairly invasive, with possible complications. Additionally, most of serum-based biomarkers such as carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9), carbohydrate antigen 72-4 (CA72-4), and carbohydrate antigen 125 (CA125) are not recommended for detection of GC due to the limit of specificity and sensitivity in the early stages of GC. Thus, it is essential to identify new biomarkers for diagnosis of early stages of GC. In this study, the investigators develop an ultradeep massive parallel sequencing (MPS) assay to detect tumor derived mutations (TDM) in plasma of early stages of GC. This study provides proof-of-principle for eventual clinical employment of circulating DNA, via liquid biopsy, for detection of early stages of GC.

Questions about this trial

What is this clinical trial studying?

An observational study of Circulating Tumor DNA (ctDNA) and Gastric Cancer, run by University Medical Center Ho Chi Minh City (UMC) at 1 site in Vietnam.

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 5 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 28 Apr 2022. 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 Vietnam. 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 Long D. Vo, MD. (+84918133915, long.vd@umc.edu.vn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The sensitivity and and specificity of our mutation-based assay for detecting early-stage gastric cancer patients (time frame: 1 months after collecting blood and specimen). 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 28 Apr 2022.
