BACKGROUND: Colonoscopy is currently widely accepted as the gold standard for detection of colorectal cancer (CRC) providing detection of up to 95% of pre-cancerous lesions during the procedure. However, certain limitations exist in most countries including cost and access to the procedure. Moreover, colonoscopy is an invasive technique with risk inherent to the endoscopic procedure. For this reason, alternative screening tests, in particular, fecal occult blood-based tests, have been widely adopted for frontline screening...

Importance: Colorectal cancer (CRC) screening is underused, especially among vulnerable populations. Decision aids and patient navigation are potentially complementary interventions for improving CRC screening rates, but their combined effect on screening completion is unknown. Objective: To determine the combined effect of a CRC screening decision aid and patient navigation compared with usual care on CRC screening completion. Design, Setting, and Participants: In this randomized clinical trial, data were collected from January 2014 to March 2016 at 2 community health center practices, 1 in North Carolina and 1 in New Mexico, serving vulnerable populations...

Purpose: While colorectal cancer (CRC) is common in Asian countries, screening for CRC is not. Moreover, CRC screening behaviors in Asian populations remain largely unknown. The present study aimed to investigate the stages of adopting CRC screening in Korea according to screening modality. Materials and Methods: Data were obtained from the 2014 Korean National Cancer Screening Survey, a cross-sectional survey that utilized nationally representative random sampling to investigate cancer screening rates...

BACKGROUND: Screening for colorectal cancer (CRC) significantly reduces mortality associated with this disease. In Australia, the National Bowel Cancer Screening Program provides regular fecal occult blood tests (FOBT) for those aged 50 to 74 years, however, participation rates in the program have plateaued at 36%. Given low uptake in the National Bowel Cancer Screening Program, it is necessary to explore alternate methods to increase CRC screening rates. Primary care is a promising adjunct setting to test methods to increase CRC screening participation...

BACKGROUND & AIMS: Among subjects screened for colorectal cancer (CRC) by the guaiac fecal occult blood test, interval cancers develop in 48%-55% of the subjects. Data are limited on how many persons screened by fecal immunochemical tests (FIT), over multiple rounds, develop interval cancers. In the Netherlands, a pilot FIT-based biennial CRC screening program was conducted between 2006 and 2014. We collected and analyzed data from the program on CRCs detected during screening (SD-CRC) and CRCs not detected within the screening program (non-SD-CRC; such as FIT interval cancers, colonoscopy interval cancers and cancer in non-participants)...

The early detection of colorectal cancer is vital for disease management and patient survival. Fecal hemoglobin detection is a widely-adopted method for screening and early diagnosis. Fecal Immunochemical Test (FIT) is favored over the older generation chemical based Fecal Occult Blood Test (FOBT) as it does not require dietary or drug restrictions, and is specific to human blood from the lower digestive tract. To date, no quantitative FIT platforms are available for use in the point-of-care setting. Here, we report proof of principle data of a novel low cost quantitative fecal immunochemical-based biosensor platform that may be further developed into a point-of-care test in low-resource settings...

Our Family Health Team is located in Toronto, Canada and provides care to over 35 000 patients. Like many practices in Canada, we took an opportunistic approach to cervical, breast, and colorectal cancer screening. We wanted to shift to a proactive, population-based approach but were unable to systematically identify patients overdue for screening or calculate baseline screening rates. Our initiative had two goals: (1) to develop a method for systematically identifying patients eligible for screening and whether they were overdue and (2) to increase screening rates for cervical, breast, and colorectal cancer...

OBJECTIVES: Fecal occult blood testing (FOBT) is performed routinely before starting therapeutic anticoagulation in patients despite it never being validated to predict gastrointestinal bleeding (GIB) risk. Our objective was to determine the utility in checking the guaiac FOBT test (gFOBT) before initiating therapeutic anticoagulation in patients with a new diagnosis of venous thromboembolism (VTE). METHODS: This was a retrospective chart review that examined patients with a diagnosis of VTE admitted during a 2-year period in one mid-sized tertiary care center...

Computed tomographic colonography (CTC) is a minimally invasive imaging examination for the colon, and is safe, well tolerated and accurate for the detection of colorectal cancer (CRC) and advanced adenoma. While the role of CTC as a primary test for population screening of CRC is under investigation, the fecal occult blood test (FOBT) has been recommended for population screening of CRC in Europe. Subjects with positive FOBT are invited to undergo total colonoscopy, which has some critical issues, such as suboptimal compliance, contraindications and the possibility of an incomplete exploration of the colon...

A 60-year-old male patient developed hyperpyrexia, cough, expectoration with blood-stained sputum, mouth ulcers, and suppurative tonsillitis after receiving 35 days of combination treatment with leflunomide (LEF) and low-dose methotrexate (MTX) for active rheumatoid arthritis. On admission, routine blood tests showed severe thrombocytopenia, agranulocytosis, and decreased hemoglobin concentration compared with the relatively normal results of 1 month previously during the first hospitalization. Chest radiography revealed inflammation in both lungs, and a fecal occult blood test was positive...

Background and aims Colonoscopy is currently the reference method to detect colorectal neoplasia, yet some adenomas remain undetected. The water infusion technique and dying with indigo carmine has shown interesting results for reducing this miss rate. The aim of this study was to compare the adenoma detection rate (adenoma and adenocarcinoma; ADR) and the mean number of adenomas per patient (MAP) for blue-water infusion colonoscopy (BWIC) versus standard colonoscopy. Methods We performed a multicenter, randomized controlled trial in eight units, including patients with a validated indication for colonoscopy (symptoms, familial or personal history, fecal occult blood test positive)...

Cancer screening rates among Latinas are generally low, reducing the likelihood of early cancer detection in this population. This article examines the effects of a community intervention (Fe en Acción/Faith in Action) led by community health workers (promotoras) on promoting breast, cervical and colorectal cancer screening among churchgoing Latinas. Sixteen churches were randomly assigned to a cancer screening or a physical activity intervention. We examined cancer knowledge, barriers to screening and self-reported mammography, clinical breast exam, Pap test, fecal occult blood test and sigmoidoscopy or colonoscopy at baseline and 12 months follow-up...

Salivary hemoglobin (Hb) for screening of periodontitis is approved under the pharmaceutical affairs law of Japan. Two reagents are commercially available for the modified fecal occult blood test: Saliva Hemo Plus and OC-AUTO S Latex Reagent. We simultaneously measured split specimens from 561 samples by using these two methods and compared the differences and agreement between both methods. Moreover, saliva samples were collected from 10 subjects at five time points during the day for analysis of circadian variations and fluctuation...

Colorectal cancer is in the top 3 of both diagnosed cancers and deaths related to cancer in the United States. Despite this, Americans are continuing to forgo colorectal cancer screening as part of their preventive health maintenance. Screening helps identify precancerous and early cancerous lesions so they can be easily treated and cured. The purpose of this study was to compare the rates of detection of adenomatous (precursors to colorectal cancer) polyps and colorectal cancer in 2 groups of asymptomatic patients: one group undergoing standard colonoscopy and the other group undergoing standard colonoscopy in conjunction with fecal occult blood testing...

Abomasal ulcers lead to several problems. They cause pain resulting in a decrease in productivity and even the possible loss of the animal. Because they are frequently difficult to diagnose, information on their prevalence is variable. Additionally, therapeutic options are limited. Abomasal ulcers are graded as type 1 through 4, type 1 being a superficial defect and type 2 an ulcer where a large blood vessel has been eroded, leading to substantial blood loss. Types 3 and 4 are perforated abomasal ulcers leading to local and diffuse peritonitis, respectively...

The American Society of Nephrology recommends against routine cancer screening among asymptomatic patients receiving maintenance dialysis on the basis of limited survival benefit. To determine the frequency of colorectal cancer screening among patients on dialysis and the extent to which screening tests were targeted toward patients at lower risk of death and higher likelihood of receiving a kidney transplant, we performed a cohort study of 469,574 Medicare beneficiaries ages ≥50 years old who received dialysis between January 1, 2007 and September 30, 2012...

BACKGROUND: The ColonCancerCheck screening program for colorectal cancer (CRC) in Ontario, Canada, is considering switching from biennial guaiac fecal occult blood test (gFOBT) screening between age 50-74 years to the more sensitive, but also less specific fecal immunochemical test (FIT). The aim of this study is to estimate whether the additional benefits of FIT screening compared to gFOBT outweigh the additional costs and harms. METHODS: We used microsimulation modeling to estimate quality adjusted life years (QALYs) gained and costs of gFOBT and FIT, compared to no screening, in a cohort of screening participants...

We report two cases of melanomas in patients who developed intestinal metastasis despite other metastatic sites responding to nivolumab and despite the patients having favorable findings such as vitiligo and normal lactate dehydrogenase. The first case is an 85-year-old man who had been administrated nivolumab for lung/cutaneous metastases. After 22 courses of nivolumab therapy, fever and anorexia had appeared and his bodyweight had decreased. An intussusception on the ileocecal valve was revealed by computed tomography, and emergency surgery revealed metastatic lesions on the colon...
