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.

Primary care provider involvement in thyroid cancer survivorship care.
While prior research has examined how primary care providers (PCPs) can care for breast and colon cancer survivors, little is known about their role in thyroid cancer survivorship. The purpose of this study was to understand PCP involvement and confidence in thyroid cancer survivorship care. The investigators found that while PCPs reported being involved in long-term surveillance, gaps remained in their confidence in handling survivorship care. They indicated that thyroid cancer survivorship guidelines that delineate PCP roles present one opportunity to increase confidence about their participation.

Effectiveness of patient navigation to increase cancer screening in populations adversely affected by health disparities: a meta-analysis.
This study evaluated the effectiveness of patient navigation to increase screening for colorectal, breast, and cervical cancer in populations adversely affected by health care disparities. Two of the investigators independently abstracted study data and assessed study quality and applicability using criteria adapted from the USPSTF. Findings indicated that, in populations adversely affected by disparities, colorectal, breast, and cervical cancer screening rates were higher in patients provided navigation services.

Completeness of operative reports for rectal cancer surgery.
This study examined the completeness of operative reports for rectal cancer surgery and whether they contain the key elements recommended by the National Accreditation Program for Rectal Cancer. Ten hospitals in Michigan submitted rectal cancer operative reports from June-December 2018. These reports were analyzed for completeness and to identify key elements in the synoptic operative template. Out of 110 reports, 31 contained all 24 elements and they all used a synoptic template. Overall, 62 reported used a synoptic template and 48 did not.

Association between indefinite dysplasia and advanced neoplasia in patients with inflammatory bowel diseases undergoing surveillance.
Little is known about the clinical significance of indefinite dysplasia (IND) in patients with inflammatory bowel diseases (IBD) undergoing colonoscopic surveillance for colorectal neoplasia. The investigators conducted a retrospective cohort analysis from 2001 through 2017. They concluded that patients with IBD undergoing colorectal neoplasia surveillance with consistent histopathologic grading of dysplasia, IND was independently associated with a significant increase in risk of advanced colorectal neoplasia.

Characteristics of patients seeking second opinions at a multidisciplinary colorectal cancer clinic.
The purpose of this study was to describe the patient and treatment characteristics of patients seeking initial and second opinions in colorectal cancer care at a multidisciplinary colorectal cancer clinic. Findings showed that patients seeking a second opinion represent a unique subset of patients with colorectal cancer. In general, they are younger and more likely to have stage IV or recurrent disease than patients seeking an initial opinion. Although transfer of care to a multidisciplinary colorectal cancer clinic after second opinion is lower than for initial consultations, multidisciplinary colorectal cancer clinics provide an important role for patients with complex disease characteristics and treatment needs.

Demographic and psychosocial factors associated with limited health literacy in a community-based sample of older Black Americans.
This study examined the frequency of limited health literacy and demographic and psychosocial factors associated with limited health literacy in a sample of older black Americans. The participants enrolled in a community-based intervention to promote colorectal cancer screening and completed baseline surveys that assessed their health literacy using the Rapid Estimate of Adult Literacy in Medicine, Revised (REALM-R) test, CRC awareness, cancer fatalism, Preventive Health Model (PHM) constructs, and demographics. Findings showed that limited health literacy was associated with multiple complex factors. Recommendations include interventions to incorporate patient health literacy and low-literacy materials that can be delivered through multiple channels.

Association of Medicaid expansion under the Affordable Care Act with insurance status, cancer stage, and timely treatment among patients with breast, colon, and lung cancer.
The effect of the Patient Protection and Affordable Care Act's Medicaid expansion on cancer care delivery and outcomes is unknown. Patients with cancer are a high-risk group for whom treatment delays are particularly detrimental. The objective of this study was to examine the association between Medicaid expansion and changes in insurance status, stage at diagnosis, and timely treatment among patients with incident breast, colon, and non-small cell lung cancer.

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.

Long-term functional decline after high-risk elective colorectal surgery in older adults.
This study examined the long-term risks of functional decline after elective colorectal surgery in older adults. This retrospective matched cohort study used data from the Health and Retirement Study, a nationally representative, longitudinal survey of adults >50 years of age. This survey collected data on functional status, cognition, and demographics, among other topics. The survey was linked with Medicare claims and National Death Index data from 1992 to 2012 and used patients 65 years and older. Surgery patients did experience a greater likelihood of functional decline with or without complications compared to control subjects. The older the patient, the more likelihood of a functional decline occurring after surgery.

Pre-operative, intra-operative, and post-operative factors associated with post-discharge venous thromboembolism following colorectal cancer resection.
Venous thromboembolism (VTE) is the most common preventable cause of 30-day post-operative mortality, with many events occurring after hospital discharge. High-level evidence supports post-discharge VTE chemoprophylaxis following abdominal/pelvic cancer resection; however, some studies support a more tailored approach. The objectives of this study were to (1) identify risk factors associated with post-discharge VTE in a large cohort of patients undergoing colorectal cancer resection and (2) develop a post-discharge VTE risk calculator.

Uptake of total mesorectal excision and total mesorectal excision grading for rectal cancer: a statewide study.
Investigators sought to assess trends in total mesorectal excision performance and grading in Michigan hospitals. They found that the rates of total mesorectal excision performance and grade assignment were widely variable throughout the state of Michigan. Overall, grade assignment remained very low, suggesting an opportunity for quality improvement projects to increase total mesorectal excision performance and grading, involving both the surgeons and pathologists for effective implementation.

Have screening harms become newsworthy? News coverage of prostate and colorectal cancer screening since the 2008 USPSTF recommendation changes.
The researchers aimed to determine whether newspapers portrayed screening for prostate and colorectal cancers differently after the 2008 USPSTF recommendation changes. In US newspapers from 2005 to 2012, they found that benefits in prostate cancer screening articles and harms and benefits in colonoscopy articles did not change over time, but mentions of prostate cancer screening harms increased after 2008. They concluded that consumers, especially lay consumers, are receiving unbalanced information on cancer screening.

Using a discrete choice experiment to inform the design of programs to promote colon cancer screening for vulnerable populations in North Carolina.
This study used a discrete choice experiment (DCE) to learn about how vulnerable individuals in North Carolina value different aspects of CRC screening programs. It found that follow-up cost coverage was most frequently found to be the most important attribute from the DCE (47 percent); followed by test reward/copayment (33 percent).

Health-care utilization by prognosis profile in a managed care setting: using the Surveillance, Epidemiology and End Results Cancer Survival Calculator SEER*CSC.
The authors described health service utilization patterns of subgroups of prostate cancer and colorectal cancer (CRC) patients with different relative probabilities of dying of their cancer or other conditions. They found that although a new diagnosis of cancer increased utilization of cancer-related services for an extended time period, the timing of cancer diagnosis did not appear to affect other types of utilization.

Cost-utility analysis of chemotherapy regimens in elderly patients with stage III colon cancer.
The authors investigated community-level evidence on the effectiveness and cost effectiveness of treatment for stage III colon cancer for elderly patients among those receiving no chemotherapy, 5-fluorouracil (5-FU), and FOLFOX (5-FU + oxaliplatin). They concluded that FOLFOX appears more effective and cost effective than other strategies for colon cancer treatment of older patients, with results being sensitive to age.

Increasing utilization and predictors of hematopoietic growth factors in patients diagnosed with colorectal cancer: findings from a large national population-based cohort in the USA, 1992-2009.
The authors examined the temporal trend and predictors of receiving hematopoietic growth factors in a large nationwide and population-based cohort of patients with colorectal cancer in the USA from 1992 to 2009. They found that gender, marital status, comorbidity scores, geographic area, year of diagnosis, tumor stage, number of lymph nodes, and risk profile for febrile neutropenia were statistically significant predictors of using colony-stimulating factors and erythropoiesis-stimulating agents.

Regional variation in colorectal cancer testing and geographic availability of care in a publicly insured population.
The researchers examined colorectal cancer (CRC) testing across regions of North Carolina by using population-based Medicare and Medicaid claims data from disabled individuals who turned 50 years of age during 2003-2008. They found that fewer than 50% of eligible individuals had evidence of CRC testing; men, African-Americans, Medicaid beneficiaries, and those living furthest away from endoscopy facilities had significantly lower odds of CRC testing, with significant regional variation.

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.
