About this study

Official title: Structural of the Gut Mucosal Microbiota is Associated With Colorectal Cancer Relapses After Curative Surgery

Colonic microbiome has been found to contribute to the development of colorectal cancer. We speculate that gut microbiota related to colorectal cancer relapse after curative treatment. This study aim to discover if any difference of gut microbiota exist in patients who suffer from cancer relapse compared with patients who do not. Finally develop patient-centred programmes of surveillance protocols base on microbiota analysis.

Read the detailed description

Treatments for colorectal cancer of all stages have evolved considerably over the past two decades, resulting in improved long-term outcomes. After curative treatment, however, 30% of patients with stage I-III and up to 65% of patients with stage IV colorectal cancer develop recurrent disease.

The human colon plays host to a diverse and metabolically complex community of microorganisms. While the colonic microbiome has been found to contribute to the development of colorectal cancer. Investigators speculate that gut microbiota related to colorectal cancer relapse after curative treatment.

Patients are routinely offered surveillance in order to detect disease recurrence at an early, asymptomatic stage, with the intention of improving survival. Nevertheless, controversy continues to surround the optimal surveillance protocols. Investigators aim to discover if any difference of gut microbiota is exist in patients who suffer from relapse compared with patients who do not.

Future surveillance after colorectal cancer treatment should focus on risk-stratification and should incorporate current knowledge on risk of recurrence in relation to the biology of the tumour as well as gut microbiota feature. Finally investigators will develop patient-centred programmes of surveillance protocols base on microbiota analysis.

RelapsePatients who suffered colorectal cancer relapse after curative surgery

What is being measured

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

  1. Transcriptional changes in gut microbiota

    16S rRNA gene sequencing will be performed with stander procedure

    Measured: Baseline, 6 months after surgery, 12 months after surgery, 24 months after surgery

Secondary outcomes (1)
  1. Epigenetic changes

    DNA methylation levels are analysed at baseline and after probiotics use in tissue samples

    Measured: Baseline, 6 months after surgery, 12 months after surgery, 24 months after surgery

Questions about this trial

What is this clinical trial studying?

An observational study of Gut Microbiota and Colorectal Cancer, run by First Affiliated Hospital of Harbin Medical University at 1 site in China.

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 4 inclusion and 11 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 9 May 2018. 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 China. 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 Yunwei Wei (+86045185553099, hydwyw11@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Transcriptional changes in gut microbiota (time frame: Baseline, 6 months after surgery, 12 months after surgery, 24 months after surgery). 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 9 May 2018.
