Trial summary

Early detecting and removing of colorectal advanced adenomas can reduce incidence of colorectal cancer. Because of the less bleeding of advanced adenomas, the sensitivity of existing quantitative fecal immunochemical test (qFIT) is unsatisfying. Read more about this study

About this study

Official title: A New Quantitative Fecal Immunochemical Test Can Improve Diagnostic Accuracy in Detecting Colorectal Advanced Adenoma.

Early detecting and removing of colorectal advanced adenomas can reduce incidence of colorectal cancer. Because of the less bleeding of advanced adenomas, the sensitivity of existing quantitative fecal immunochemical test (qFIT) is unsatisfying. A new technology qFIT, which have a higher sensitivity in extremely low concentration of hemoglobin compared with existing commercially available qFIT, is developed and this study will prove the high diagnostic accuracy in detecting colorectal advanced adenoma.

Read the detailed description

Colorectal cancer accounts for approximately 10% of all annually diagnosed cancers and cancer-related deaths worldwide. With progress of developing countries, it is predicted that the incidence of colorectal cancer worldwide will increase to 2.5 million new cases in 2035. The majority of colorectal cancer is thought to arise from precancerous lesions through the adenoma-carcinoma pathway. Detecting and removing of colorectal advanced adenomas can reduce incidence of colorectal cancer. Although colonoscopy is currently considered the most effective method for detecting advanced adenomas, individuals may be reluctant to undergo colonoscopy due to the uncomfortable feeling and the relatively high cost of colonoscopy. Conversely, stool tests are relatively cheap and more readily accepted. Annual fecal immunochemical test (FIT), one of the preferred methods of colorectal cancer screening, is economic and easy to use. However, the existing commercially available qFIT is insufficiently sensitive to the minor hemorrhage of advanced adenomas, and the sensitivity is about only 27% to 47%. To improve diagnostic accuracy in detecting colorectal advanced adenoma, an improved technology of qFIT, which have a higher sensitivity in extremely low concentration of hemoglobin in stool compared with existing commercially available qFIT, is developed. The investigators design this research to prove the diagnostic accuracy of the new qFIT in detecting colorectal advanced adenoma.

Questions about this trial

What is this clinical trial studying?

An observational study of Colorectal Adenoma and Colorectal Neoplasm, run by Shandong 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 2 inclusion and 6 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 18 Jun 2021. 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?

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 accuracy of the new qFIT to diagnose colorectal advanced adenoma. (time frame: 18 months). 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 18 Jun 2021.
