Fecal DNA for noninvasive diagnosis of colorectal cancer in immunochemical fecal occult blood test-positive individuals.
BACKGROUND We aimed to define the potential of the fecal DNA assay as an alternative or in addition to the currently used immunochemical fecal occult blood test (iFOBT) for the early diagnosis of colorectal cancer. METHODS A total of 560 individuals aged 50 to 69 years with a positive iFOBT were recruited from an Italian FOBT regional screening program. Twenty-six were diagnosed with adenocar...
متن کاملDigital rectal examination versus spontaneous passage of stool for fecal occult blood testing.
BACKGROUND The diagnostic value of a positive fecal occult blood test (FOBT) at the time of digital rectal examination (DRE) is disputed despite being used commonly by a significant number of physicians. A meta-analysis was conducted to evaluate FOBT by DRE for detecting neoplasia versus FOBT on stool passed spontaneously (SPS) in asymptomatic patients undergoing colorectal cancer screening. ...
متن کاملAccuracy of screening for fecal occult blood on a single stool sample obtained by digital rectal examination: a comparison with recommended sampling practice.
BACKGROUND Many expert panels recommend colorectal cancer screening for average-risk asymptomatic individuals older than 50 years of age. Recent studies have found that 24% to 64% of primary care providers use only the digital fecal occult blood test (FOBT) as their primary screening test. The effectiveness of a single digital FOBT is unknown. OBJECTIVE To compare the sensitivity and specific...
متن کاملImmunochemical fecal occult blood tests for colorectal cancer screening.
BACKGROUND The superiority of several immunochemical fecal occult blood tests (I-FOBT) over guaiac-based tests in colorectal cancer screening is now established. The aim of this study was to compare the analytical performance of 3 quantitative I-FOBTs. METHODS Stool samples from 10 healthy volunteers, initially I-FOBT negative, supplemented with human blood, were used to compare reproducibili...
متن کاملClinical impact of the immunochemical fecal occult blood test for colorectal cancer screening in Brazil
BACKGROUND Colorectal cancer (CRC) screening programs based on the fecal occult blood test (FOBT) reduce CRC mortality. We carried out an observational prospective study to determine the accuracy of immunochemical FOBTs for the detection of CRC in individuals at average risk for the disease. METHODS This population-based study was performed between April 2015 and January 2016 in two gastroent...
