unochemical Fecal Occult Blood Test–Positive Individuals

Downlo kground: We aimed to define the potential of the fecal DNA assay as an alternative or in addition to rrently used immunochemical fecal occult blood test (iFOBT) for the early diagnosis of colorectal . thods: A total of 560 individuals aged 50 to 69 years with a positive iFOBT were recruited from an FOBT regional screening program.

Fecal occult blood test screening for colorectal cancer.

In summary, high-quality scientific studies indicate that the use of the FOBT for colorectal cancer screening has a number of important advantages. The test is capable of detecting most early colorectal cancers and many advanced adenomas. It has been shown in randomized, controlled trials to reduce substantially colorectal cancer mortality and incidence. The FOBT is feasible, widely available, ...

Fecal occult blood testing for colorectal cancer: a perspective.

Colorectal cancer is an important health problem in western countries. Early detection of colorectal cancer reduces mortality. The best evidence for the effectiveness of screening for colorectal cancer is with annual or biennial fecal occult blood testing. While the benefit of fecal occult blood testing is small in absolute terms, the incremental cost-effectiveness of this screening strategy ap...
