Colorectal cancer (CRC) is a common malignant neoplasm worldwide. It is important to identify new biomarkers for the early detection of CRC. In this study, magnetic beads and the Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) platform were used to analyse CRC and healthy control (HC) serum samples. The CRC diagnosis pattern was established to have a specificity of 94.7% and sensitivity of 92.3% in a blind test. The candidate biomarker serine/threonine kinase 4 (STK4, also known as MST1) was identified by Tandem mass spectrometry (MS/MS) and verified with western blotting and enzyme-linked immunosorbent assay (ELISA)...

BACKGROUND AND AIM: Although mortality rates of colorectal cancer (CRC) have been increasing in Japan, its screening rates remain stagnant at 19.2% among Japanese population aged >40 years in 2014. To evaluate the importance of CRC screening by fecal occult blood test (FOBT), we estimated the incidence of FOBT-positivity and CRC by sex-age stratification and clarified the risk factors for CRC. METHODS: Between 2007 and 2014, 56,324 residents (21,517 men and 34,807 women) were enrolled in this study...

To analyze the sociodemographic and organizational factors influencing participation in population-based colorectal cancer screening programs (CRCSP) in Spain, a retrospective study was conducted in a cohort of people invited to participate in the first 3 screening rounds of 6 CRCSP from 2000 to 2012. Mixed logistic regression models were used to analyze the relationship between sociodemographic and organizational factors, such as the type of fecal occult blood test (FOBT) used and the FOBT delivery type. The analysis was performed separately in groups (Initial screening-first invitation, Subsequent invitation for previous never-responders, Subsequent invitation-regular, Subsequent invitation-irregular intervals)...

The qualitative-quantitative study investigates the co-existence of barriers and levers to FOBT screening in 5894 individuals reluctant to be screened, identifying operational motivational patterns that may increase screening compliance. Co-occurrence analysis was performed according to three motivational conditions (barriers, levers, or both).Cluster analysis then identified motivational predictors of effective screening. One quarter of the individuals who had refused screening nevertheless expressed at least one motivation towards FOBT...

Backgrounds; Fecal occult blood testing (FOBT) is an important diagnostic tool for the detection of colorectal cancer. However, it has not been standardized due to the absence of suitable specimens for surveillance. Methods; We developed a ready-to-use artificial stool made from rice flour. This new artificial stool homogeneously contains not only human hemoglobin A0(HbA0), but also glycerol as an internal standard material. After the collection of the artificial stool into a buffer, the Hb concentration in dispersed solution was measured using a method based on the peroxidase like activity of Hb...

Colorectal cancer (CRC) screening is a cost-effective prevention and control strategy. However, the promotion of CRC screening for older adults may be difficult because reading CRC prevention information may evoke embarrassment, fear, and anxiety towards the screening procedure and cancer diagnosis. This study aims to (1) examine the effects of three promotional materials for CRC screening on the attitudes toward CRC screening tests (screening interest, screening effectiveness, and trust in the screening results) and cancer fear, and (2) to explore the interaction effect of cancer fear with screening effectiveness and trust in the screening results on screening interest of the three screening tests (fecal occult blood test (FOBT), flexible sigmoidoscopy, and colonoscopy) among Chinese older adults...

The month of March is dedicated to Colon Cancer Awareness. Worldwide, colorectal cancer (CRC) incidence has been on the rise. It is currently the third most common cancer in men (746,000 cases, 10.0% of the total) and the second in women (614,000 cases, 9.2% of the total).1 Arecent meta-analysis reported a 61% risk reduction in CRC incidence with colonoscopy.2 Unlike screening programs for breast and prostate cancers, not only has CRC screening reduced mortality from colon cancer and detected early CRC, it has also decreased the incidence of CRC through detection and removal of pre-cancerous lesions...

Colorectal cancer, the second leading cause of mortality in the USA, can be prevented with colorectal cancer screening. However, many people who should receive the screening do not get screened. To learn more, this study estimated the prevalence of up-to-date colorectal cancer (CRC) screening and examined the relationship between CRC knowledge and screening compliance among Asian Americans living in the Baltimore-Washington Metropolitan area. The study included a cross-sectional sample of 274 Chinese, Korean, and Vietnamese Americans aged 50-75 years old...

Screening for colorectal cancer is now integrated into the fabric of healthcare systems across the world, as a wealth of evidence exists as regards its benefits in reducing cancer-specific mortality through the detection of early-stage disease. Options for screening include both endoscopic and stool-based tests, with a majority of countries opting for repeated faecal occult blood screening tests (FOBt). These can be either guaiac-based, as is the current system across the UK, or immunoglobulin-based, as is the case in the accompanying article from Spain...

A population-based program promoting the Fecal Occult Blood Test (FOBT) for colorectal cancer screening was introduced in 2008 in Ontario, Canada, where opportunistic screening with colonoscopy had been increasing in frequency. We evaluated the impact of the program on income and immigration-related disparities in screening. We used linked administrative data to calculate colorectal cancer screening rates for eligible Ontarians in each year between 2001/02 (n=2,852,619) and 2013/14 (n=4,139,304). We quantified disparities using an "inequality ratio" of screening rates in the most disadvantaged group relative to the most advantaged group...
