May 3, 2021 updated by: Yanqing Li, Shandong University

A Comparison of Quantitative Fecal Immunochemical Test and Qualitative Fecal Occult Blood Test for Colorectal Cancer Screening in Medium and High Risk Screening Population

Colorectal cancer is a leading cause of cancer-related morbidity and mortality. CRC-related death can be prevented through fecal occult blood test screening. Because of economic and high sensitivity, fecal immunochemical test is recommended for screening population of CRC. The purpose of this study is to compare the accuracy of 4 different fecal occult blood testing in medium and high risk screening population in Chinese.

Detailed Description

Colorectal cancer (CRC) is one of the most common cancer worldwide, and cause a huge number of cancer-associated mortality. CRC screening has been shown to be effective in reducing the incidence of, and mortality from, CRC. There are several recommended screening options for screening population of CRC, including colonoscopy and fecal occult blood testing (FOBT) .Colonoscopy has higher sensitivity and specificity than FOBT for detecting advanced colorectal neoplasia but also has several disadvantages, including higher cost and poorer compliance. Therefore, many patients prefer FOBT to colonoscopy. FOBT includes guaiac-based fecal occult blood test (gFOBT) and fecal immunochemical test (FIT). FIT includes quantitative FIT (qFIT) and qualitative FIT. qFIT can provide a value of concentration of hemoglobin in stool and are increasingly recommended for CRC. In China, the most common use FOBT is qualitative FIT and the comparison of quantitative and qualitative FIT is lack in screening population of CRC in Chinese. To add to the evidence on FIT performance characteristics for detection of CRC, the investigators design this research to compare qFIT with other 3 qualitative FOBT（two of them are colloidal gold qualitative FITs and one of them is chemical and immunologic combined detection）in medium and high risk screening population.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame

Time Frame: 6 months
The sensitivity, specificity, positive predictive value and negative predictive value of these 4 FOBTs to detect CRC.
6 months
The accuracy of 4 kind of FOBTs to diagnose advanced colorectal neoplasm.
Time Frame: 6 months
The sensitivity, specificity, positive predictive value and negative predictive value of these 4 FOBTs to detect advanced colorectal neoplasm.
6 months
The accuracy of 4 kind of FOBTs to diagnose advanced adenoma.
Time Frame: 6 months
The sensitivity, specificity, positive predictive value and negative predictive value of these 4 FOBTs to detect advanced adenoma.
6 months
Develop a predictive model of CRC or advanced colorectal neoplasm which includes qFIT.
Time Frame: 6 months
Develop a predictive model of CRC or advanced colorectal neoplasm which includes qFIT, age ,sex, CRC family history and so on.
6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Explore the cost-benefit ratio of one or two-sample of qFIT.
Time Frame: 6 month
Explore the cost-benefit ratio of one or two-sample of qFIT.
6 month
Explore the reason of false positive of qFIT
Time Frame: 6 month
Calculate false positive rate of the 4 kind of FOBTs. and count the case number of inflammatory bowel disease, colonic diverticulitis, hemorrhoids, upper gastrointestinal disease or medical factors that cause false positive of qFIT.
6 month
Explore the effect of aspirin or other anticoagulants to the diagnose accuracy of qFIT
Time Frame: 6 month
