CONTEXT Dietary restriction is often recommended during fecal occult blood testing (FOBT) as a means of increasing test accuracy, but concern surrounds whether such restriction also reduces the chance that patients will complete the test. PURPOSE We conducted a systematic review and meta-analysis to determine if advice about dietary restrictions affects the rate of completion of FOBT and the ...

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. ...

BACKGROUND The purpose of this study was to identify factors associated with colorectal cancer (CRC) screening test preference and examine the association between test preference and test completed. METHODS Patients (n = 1224) were 50-70 years, at average CRC risk, and overdue for screening. Outcome variables were preference for fecal occult blood test (FOBT), colonoscopy (COL), sigmoidoscopy...

BACKGROUND Screening using fecal occult blood testing (FOBt) reduces colorectal cancer mortality, but the test has low sensitivity. A "missed" cancer may cause psychologic harms in the screened population that partially counteract the benefits of early detection. METHODS Three hundred and eleven people diagnosed with colorectal cancer (i) after a negative FOBt result (interval cancer), (ii) a...

AIM The aims of the current study were to assess the validity of the fecal occult blood test (FOBT) in an organized screening setting in Korea and to determine factors associated with FOBT validity, such as screening round, age group, and anatomical location of the cancer. METHODS Study participants were those who were 50 years and older who received an FOBT through the National Cancer Screen...

BACKGROUND Fecal occult blood testing (FOBT) is a widely used screening test for colorectal cancer (CRC). Given the limited data about the effects of warfarin on FOBT are inconclusive, current screening guidelines for CRC do not address whether warfarin should be discontinued before FOBT. Therefore, we conducted a meta-analysis to evaluate the influence of warfarin on the yield of FOBT. METHO...

Individuals with colorectal cancer (CRC) have a tendency to intestinal bleeding which may result in mild to severe iron deficiency anemia, but for many colon cancer patients hematological abnormalities are subtle. The fecal occult blood test (FOBT) is used as a pre-screening test whereby those with a positive FOBT are referred to colonscopy. We sought to determine if information contained in th...

AIMS AND BACKGROUND The best screening strategy for colorectal cancer is still debated. We simulated two screening strategies, namely flexible sigmoidoscopy (single episode) and immunological fecal occult blood test (FOBT) (five biennial rounds) and comparing their results as regards advanced adenomas and colorectal cancer detection. METHODS A Markov model was developed to estimate the number...

BACKGROUND After lung and prostate cancers, colorectal cancer (CRC) is the third most common cancer in men and the second most common cancer in women after breast cancer worldwide. Every year, more than one million people are diagnosed with colorectal cancer worldwide and half of these patients die from this disease, making it the fourth leading cause of death in the world. This systematic revi...

Enteric helminthic infection is one of the most important public health issues in developing countries. These infections are transmitted by faeco-oral route and cause significant morbidity among patients of all age groups, especially in school age and preschool age children. The clinical presentation may be vague and non-specific. Frequently, patients with enteric helminthic infection (especial...
