Reappraising risk factors for inflammatory bowel disease-associated neoplasia: implications for colonoscopic surveillance in IBD.
One of the most feared complications of inflammatory bowel disease [IBD]-associated colitis is colorectal cancer. An opportunity for early detection is being missed in a group that is overlooked as high-risk, as a substantial proportion of colorectal cancers are being diagnosed in individuals with colonic IBD who have disease duration shorter than when guidelines recommend surveillance initiation. In this study, the investigators discuss a viewpoint that supports a paradigm shift that will ideally result in a more effective and higher-value colorectal cancer prevention approach in IBD.

A systematic review of repeat fecal occult blood tests for colorectal cancer screening.
This systematic review examined the prevalence of repeat fecal occult blood tests (FOBT) for colorectal cancer screening. MEDLINE, Embase, and the Cochrane Library were searched for studies published from 1997 to 2017 and reported repeat FOBT over 2 and more screening rounds. Thirty-five articles (n=27) were identified which measured repeat FOBT as 1) proportion of Round 1 participants completing repeat FOBT in Round 2; 2) proportion completing two, consecutive FOBTs; or 3) proportion completing 3 or more rounds. The number of participants completing Round 1 ranged from 24.6% to 89.6%. Those who completed Round 2 ranged from 16.4% to 80%; and completion of 3 or more rounds ranged from 0.8% to 64.1%. Repeat FOBT was higher in mailed outreach than opportunistic screening.

Clinical exome sequencing vs. usual care for hereditary colorectal cancer diagnosis: a pilot comparative effectiveness study.
The purpose of this study was to evaluate clinical exome sequencing (CES) compared to usual care (UC) in the diagnostic work-up of inherited colorectal cancer/polyposis (CRCP) in a randomized controlled trial (RCT). The investigators indicate that their results suggest that CES provides similar clinical benefits to multi-gene panels in the diagnosis of hereditary CRCP.

Ambulatory safety nets to reduce missed and delayed diagnoses of cancer.
An ambulatory safety net (ASN) is an innovative organizational intervention for addressing patient safety related to missed and delayed diagnoses of abnormal test results. ASNs consist of a set of tools, reports and registries, and associated work flows to create a high-reliability system for abnormal test result management. In this paper, two ASNs implemented at an academic medical center are described, one focusing on colon cancer and the other on lung cancer.

Patterns and predictors of repeat fecal immunochemical and occult blood test screening in four large health care systems in the United States.
The objectives of this study were to characterize screening patterns and identify factors associated with repeat screening among patients who completed an index guaiac fecal occult blood test (gFOBT) or fecal immunochemical test (FIT). The investigators found that screening patterns varied substantially across healthcare systems, with consistent screening proportions ranging from 1 to 54.3% and no repeat screening proportions ranging from 6.9 to 42.8%. Consistent screening increased with older age but was less common among racial/ethnic minorities and patients with more comorbidities.

Inadequate utilization of diagnostic colonoscopy following abnormal FIT results in an integrated safety-net system.
The effectiveness of stool-based colorectal cancer (CRC) screening is contingent on colonoscopy completion in patients with an abnormal fecal immunochemical test (FIT). This study found that FIT positive patients never referred to gastroenterology or who missed their appointment after referrals were more likely to have comorbid conditions and documented illicit substance use compared with patients who completed a colonoscopy.

Reasons for lack of diagnostic colonoscopy after positive result on fecal immunochemical test in a safety-net health system.
This study aimed to characterize factors contributing to lack of follow-up colonoscopy in a racially diverse and socioeconomically disadvantaged cohort of patients with abnormal results on the fecal immunochemical test receiving care in an integrated safety-net health system. It concluded that lack of diagnostic evaluation is related to a combination of patient-, provider-, and system-level factors, highlighting the need for multilevel interventions to improve follow-up colonoscopy completion rates.

Colorectal cancer outcomes and treatment patterns in patients too young for average-risk screening.
The researchers investigated the national treatment patterns and outcomes of patients younger than 50 with colorectal cancer (CRC). They found that patients with CRC diagnosed at age <50 years are more likely to present with advanced-stage disease. However, they receive more aggressive therapy and achieve longer disease-specific survival, despite the greater percentage of patients with advanced-stage disease.

Electronic trigger-based intervention to reduce delays in diagnostic evaluation for cancer: a cluster randomized controlled trial.
The researchers tested whether prospective use of electronic health record-based trigger algorithms to identify patients at risk of diagnostic delays could prevent delays in diagnostic evaluation for cancer. They found that electronic trigger-based interventions seem to be effective in reducing time to diagnostic evaluation of colorectal and prostate cancer as well as improving the proportion of patients who receive follow-up.

Next-generation sequencing panels for the diagnosis of colorectal cancer and polyposis syndromes: a cost-effectiveness analysis.
The researchers evaluated the cost effectiveness of next-generation sequencing (NGS) panels for the diagnosis of colorectal cancer and polyposis (CRCP) syndromes in patients referred to cancer genetics clinics. They concluded that the use of an NGS panel that includes genes associated with highly penetrant CRCP syndromes in addition to Lynch syndrome genes as a first-line test is likely to provide meaningful clinical benefits in a cost-effective manner.

Physicians, clinics, and neighborhoods: multiple levels of influence on colorectal cancer screening.
The researchers described variability in colorectal cancer (CRC) test use across multiple levels, including physician, clinic, and neighborhood; and (ii) compared the performance of novel cross-classified models versus traditional hierarchical models. Significant variability was observed across all levels in both hierarchical and cross-classified models that was unexplained by measured covariates. For colonoscopy, variance was similar across all levels.
