Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 46 to 97 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: The study population is part of the Swedish Twin Registry (STR), which collected questionnaire data from all twins born after 1886. The data in this specific study is a subset of the Screening Across the Lifespan (SALT) study within the STR, in which all twins born between 1911-1958 were interviewed between 1998-2002. The subcohort named TwinGene was set-up between the years 2004 and 2008 when participants were invited to respond to a questionnaire on common diseases and provide a blood sample.

  1. Inclusion Criteria:
  • participants from the Screening Across the Lifespan (SALT) study within Swedish Twin Registry (STR) who responded to a questionnaire on common diseases and provide a blood sample;
  • both twins in the pair had to be alive and living in Sweden;
  • had been enrolled in other STR DNA sampling projects;
  1. Exclusion Criteria:
  • previously declined participation in future studies;
  • whose blood samples were unavailable or didn't pass initial lab-based QC;
  • whose samples were unable to link to the available environmental data.

About this study

Official title: Multi-omics Approach for Identification of Etiopathogenesis and Early Detection Biomarkers of Stomach Cancer Precursor Lesions

The overall aim is to utilize multi-omics approach to identify novel etiopathogenesis and early detection biomarkers for stomach cancer precursor lesions. To achieve this aim, first the investigators will use stored serum samples to perform metabolomics profiling among 12,599 twin subjects, among whom 1034 were deemed to have chronic atrophic gastritis based on measured pepsinogen I and II levels. Logistic regression will be used to search for metabolites related to the risk of chronic atrophic gastritis. Second, the investigators will further measure serum proteome by using two quantitatively precise proteomics assays, among the above-mentioned twin subjects. Identified protein biomarkers will be combined with metabolomics biomarkers to create a prediction model for chronic atrophic gastritis. The results will hopefully improve our understanding of the etiological factors and provide promising early detection biomarkers for stomach cancer precursor lesions.

Read the detailed description

The study population is part of the Swedish Twin Registry (STR), which has since its establishment in the late 1950s collected questionnaire data from all twins born after 1886. The data in this specific study is a subset of the Screening Across the Lifespan (SALT) study within the STR, in which all twins born between 1911-1958 were interviewed between 1998-2002. The subcohort named TwinGene was set-up between the years 2004 and 2008 when participants were invited to respond to a questionnaire on common diseases and provide a blood sample. Samples were collected from 12,618 twins born 1958 or earlier, of which blood sample from 12,609 were available. After excluding 10 samples which were unable to link to the available environmental data, a total of 12,599 blood samples were analyzed. Corpus-dominant CAG was characterized by a PGI/PGII ratio of less than 3. Metabolomic profiling using serum samples has been performed based on Nightingale Blood Biomarker Analysis platform. Proteomic profiling will be performed by both Scanning SWATH and OLINK® Explore 384 Oncology panel. History of H. pylori infection is examined by measuring serum IgG antibodies against H. pylori, using ELISA. Detailed lifestyle information collected by questionnaires includes education, smoking, snuff dipping, alcohol drinking, drug use, diet, and height/weight, etc. Metabolites will be log transformed prior to analyses, due to its usually skewed distribution. For each metabolite, firstly, CAG patients will be compared with all the CAG-free controls. Wilcoxon-Mann-Whitney test or Kruskal-Wallis test will be used for comparing differences of protein expressions between CAG and non-CAG groups, and multiple comparisons will be adjusted using Bonferroni correction. Generalized estimation equation (GEE) models with the robust option will be fitted to estimate the odds ratios (ORs). Second, in the comparison with MZ co-twin controls and DZ co-twin controls, only complete twin pairs with discordant CAG will be included in the study. Specifically, conditional logistic regression models will be used to control for the matching within co-twin pairs. The investigators will further combine metabolomics and proteomics data, and try to build up a CAG prediction model. Covariates will include age, sex, H. pylori seropositivity, education level, smoking, snuff dipping, and alcohol drinking. Joint effects of different metabolites and interaction with other covariates will also be examined.

Questions about this trial

What is this clinical trial studying?

An observational study of Chronic Atrophic Gastritis, run by Karolinska Institutet at 1 site in Sweden.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

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: under way, not looking for participants, as of the sponsor's last update on 21 Feb 2024. 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 Sweden. 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?

This study is still under way. Results are not available in the source record yet.

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?

Chronic atrophic gastritis (time frame: 1 Sep. 2020 to 31 Dec. 2021). 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 Feb 2024.
