OBJECTIVES: The fecal immunochemical test (FIT) has low sensitivity for detecting advanced colorectal neoplasia (ACRN); thus, a considerable portion of FIT-negative persons may have ACRN. We aimed to develop a risk-scoring model for predicting ACRN in FIT-negative persons. MATERIALS AND METHODS: We reviewed the records of participants aged ≥40 years who underwent a colonoscopy and FIT during a health check-up. We developed a risk-scoring model for predicting ACRN in FIT-negative persons...

BACKGROUND: Flexible sigmoidoscopy and fecal immunochemical tests are established diagnostic tests for colorectal cancer (CRC) screening and less invasive, less expensive, and easier to conduct than colonoscopy. However, little is known about their joint diagnostic performance compared to colonoscopy. We aimed to assess the expected diagnostic performance of joint use of flexible sigmoidoscopy and fecal immunochemical test. METHODS: We assessed the overall and site-specific prevalences of colorectal neoplasms and the overall and site-specific sensitivity, specificity, area under the receiver operating characteristics curve of a quantitative fecal immunochemical test (FOB Gold) among 3,466 participants in screening colonoscopy in Germany...

Fecal immunochemical tests (FITs) for hemoglobin (Hb) are increasingly used for colorectal cancer (CRC) screening. We aimed to review, summarize and compare reported diagnostic performance of various FITs. PubMed and Web of Science were searched from inception to 24 July 2017. Data on diagnostic performance of quantitative FITs, conducted in colonoscopy-controlled average-risk screening populations, were extracted. Summary receiver operating characteristic (ROC) curves were plotted and correlations between thresholds, positivity rates (PRs), sensitivities and specificities were assessed...

Background: Stool tests can predict advanced neoplasms prior to colonoscopy. Results of immunochemical stool tests to predict findings at colonoscopy for various indications are less often reported. We compared pre-colonoscopy stool tests with findings in patients undergoing colonoscopy for different indications. Patients and methods: Charts of patients undergoing elective or semi-urgent colonoscopy were reviewed. Comparison of adenoma detection rates and pathological findings was made between prescreened and non-prescreened, and between stool-positive and stool-negative cases...

The current study examines changes in awareness and health beliefs from baseline to 12 months post-intervention following receipt of one of two colorectal cancer (CRC) educational interventions that aimed to promote CRC screening among a racially and ethnically diverse and medically underserved population. Participants (N = 270) were enrolled in a randomized controlled trial to increase CRC screening and completed both baseline and 12-month follow-up assessments. Participants were aged 50-75, at average CRC risk, not up-to-date with CRC screening guidelines, and receiving care at one of three community-based clinics...

A 86-year-old female had a positive fecal immunochemical test, and a subsequent colonoscopy revealed a whitish, flat elevated lesion (Paris class IIa) 10 mm in diameter in the ascending colon (Figure 1, A). Biopsy was performed and histology confirmed sessile serrated adenoma/polyp (SSA/P). At 2 years, the lesion changed into a flat elevated lesion with depression (Paris class IIa+IIc) 12 mm in diameter (Figure 1, B). However, she refused endoscopic resection because of older age. At 4 years, the lesion increased to 15 mm in diameter, and the right side of the lesion was reddish (Figure 1, C)...

BACKGROUND: Screening with the fecal immunochemical test (FIT) is effective in reducing deaths from colorectal cancer (CRC). Since 2004, biennial FIT screening has been available to a target population in Taiwan as a national screening program. The objective of the current study was to identify the factors that influence willingness to undergo a confirmatory colonoscopy after a positive FIT, because related references in the published literature were scarce. METHODS: A semistructured questionnaire was based on the Health Belief Model (HBM) and a literature review...

BACKGROUND: Patients who receive an abnormal cancer screening result require follow-up for diagnostic testing, but the time to follow-up varies across patients and practices. METHODS: We used a simulation study to estimate the change in lifetime screening benefits when time to follow-up for breast, cervical, and colorectal cancers was increased. Estimates were based on four independently developed microsimulation models that each simulated the life course of adults eligible for breast (women aged 50-74 years), cervical (women aged 21-65 years), or colorectal (adults aged 50-75 years) cancer screening...

BACKGROUND & AIMS: Inflammatory bowel disease (IBD) is a chronic disease usually diagnosed after the appearance of gastrointestinal symptoms. Little is known about IBD progression during its early and even preclinical phases. We aimed to determine the number of new incidental diagnoses of IBD in an older population, and evaluate disease progression from its early stages. METHODS: We performed a retrospective analysis of 31,005 colonoscopies performed during colorectal cancer screening of patients with positive results from fecal immunochemical tests, at 11 centers in the Basque Country (Spain) from 2009 through 2014...

The rates of colorectal cancer (CRC) interval surveyed in screen-detected patients using a fecal immunochemical test (FIT) are not negligible. The aim of this study was to assess the effect of interval cancer on outcomes compared with a population with cancer diagnosed after a positive test result. All patients between 50 and 71 years of age, who were residents of the Mantua district, affected by CRC and operated on from 2005 to 2010 were reviewed. Other than patient-related, disease-related, and treatment-related factors and tumor location, this population was differentiated as either participating or not to screening and then into populations developing interval cancer after a negative FIT result...
