Study population: The probands will be selected from colorectal cancer patients meeting Chinese Lynch syndrome criteria. The blood relatives verifying germline mutation will be selected from whose proband has germline mutation(s).

For probands, the inclusion criteria: all of the following three points should be satisfied:

  1. One of the colorectal cancer patients from families meeting Chinese Lynch syndrome criteria. Chinese Lynch syndrome criteria: In a pedigree, there were at least 2 patients with histological-proven colorectal cancer, and among these, at least two patients are first-degree relatives of each other. Besides, any one of the following three points should be satisfied in the pedigree:
  2. at least one patients with multiple primary colorectal carcinoma/adenoma, either synchronously or metachronously.
  3. at least one colorectal cancer diagnosed before 50 years old. C. in the pedigree, at least one patient diagnosed with other Lynch syndrome associated cancer (ie, gastric, endometrial, small bowel, ureter, or renal-pelvic, ovarian and hepatobiliary cancers).
  4. With sufficient blood to test;
  5. Agree to provide basic information, clinical information and family history of cancer information.

For probands, the exclusion criteria:

With at least one blood relative with known pathogenic germline mutation(s).

For blood relatives verifying germline mutation, the inclusion criteria: all of the following three points should be satisfied:

  1. First- to second-degree blood relatives of probands with germline mutation(s).
  2. With sufficient blood to test.
  3. Agree to provide basic information, clinical information and family history of cancer information.

For blood relatives verifying germline mutation, the exclusion criteria:

Blood relatives who refuse to test.

About this study

Official title: Diagnosis of Lynch Syndrome Based on Next-generation Sequencing in Colorectal Cancer Patients Meeting Chinese Lynch Syndrome Criteria: An Open-label and Multi-center Study.

The purpose of this study is to find out the proportion of patients diagnosed with Lynch syndrome in colorectal cacner patients meeting Chinese Lynch syndrome criteria. Besides, this study is aimed to analyze the clinical characteristics and germline mutation of Lynch syndrome in Chinese population.

Read the detailed description
  1. Detect germline mutation (by next-generation squencing) in probands.
  2. Verify the germline mutation in blood relatives whose proband has known germline mutation(s).
  3. Analyze the test data with clinical and family information. Diagnose Lynch syndrome in the included population.
  4. Analyze the clinical characteristics and germline mutation of Lynch syndrome in Chinese population.

What participants receive

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

  • next-generation sequencingOther

    Use next-generation sequencing to test germline mutation.

What is being measured

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

  1. Pathogenic germline mutation

    Pathogenic germline mutation using next-generation sequencing with a targeted panel.

    Measured: Upon completion of study, on average 2 years.

Secondary outcomes (1)

Questions about this trial

What is this clinical trial studying?

An observational study of Lynch Syndrome, run by Second Affiliated Hospital, Zhejiang University, School of Medicine at 3 sites in China.

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

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 Aug 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites 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?

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?

Pathogenic germline mutation (time frame: Upon completion of study, on average 2 years.). 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 11 Aug 2021.
