Detailed Description:
Colorectal cancer is a major cause of cancer deaths in many countries. Therefore, the importance of screening for the early detection of colorectal cancer is evident. Fecal occult blood screening is proving to be an effective tool for detecting premalignant adenomas and colon cancer since the guaiac-based test was introduced in the late 1960s. However, several immunochemical fecal occult blood tests (IFOBTs) have become commercially available and the majority of these have demonstrated equal or superior sensitivities and specificities than the guaiac-based tests. Therefore, IFOBTs are replacing guaiac based tests despite their higher costs.In this study we evaluate the diagnostic accuracy of a new IFOBT and compare with the findings on colonoscopy.
