"Their whole lives are going to change": a photo-elicitation study of rectal cancer survivorship.
This novel study aimed to explore the rectal cancer survivor experience and identify the impacts of treatment using photo-elicitation. Patients were instructed to take photographs that showed aspects of life that are now challenges since undergoing treatment and then were interviewed. Twenty patients participated in the study at a cancer center in a tertiary medical center. Three major themes emerged regarding life after rectal cancer and its treatments: physical symptoms, lifestyle changes, and changes over time. Physical symptoms included GI issues, ostomy difficulties, and genitourinary symptoms. Lifestyle changes related to diet, social life, and hobbies as well as major life changes and finances. Finally, patients spoke of improvements after treatment and impact on daily life. A video abstract is included.

Comparative effectiveness of surveillance colonoscopy intervals on colorectal cancer outcomes in a national cohort of patients with inflammatory bowel disease.
The purpose of this study was to determine the comparative effectiveness of varying colonoscopy intervals on colorectal cancer (CRC) outcomes among patients with inflammatory bowel disease (IBD). Data was from the National Veterans Health Administration. Findings showed that, in a national cohort of patients with CRC-IBD, colonoscopy within 3 years prior to CRC diagnosis was associated with early tumor stage at diagnosis, and colonoscopy within 1 year was associated with a reduced all-cause mortality compared with no colonoscopy, supporting colonoscopy intervals of 1 to 3 years in patients with IBD in order to reduce late-stage CRC and all-cause mortality.

Effect of a patient decision aid on preferences for colorectal cancer screening among older adults: a secondary analysis of a randomized clinical trial.
This research studied the effects of a patient decision aid on preferences for colorectal cancer (CRC) screening among adults aged 76 to 84 years. Participants were recruited from 14 community-based primary care practices who were not up to date with screening and had an appointment within 6 weeks. They were randomized to receive the intervention or control. Among the 424 participants, mean age was 76.8, 248 were women, and 333 were White. There were no statistically significant differences found in patient preferences between the health groups. Additional studies that are appropriately powered were recommended.

Assessing the impact of multicomponent interventions on colorectal cancer screening through simulation: what would it take to reach national screening targets in North Carolina?
The authors simulated the impact of multicomponent interventions in North Carolina over 5 years to assess the potential for meeting national screening targets for colorectal cancer (CRC). They reported that each multicomponent intervention was associated with increased CRC screening and averted both CRC cases and deaths, while three had the potential to reach screening targets.

Barriers to colorectal cancer screening and surveillance in homeless patients: a case report and policy recommendations.
Researchers described the barriers encountered by a homeless patient with a history of colorectal cancer who was lost to follow up and presented 11 years later with a new primary colon cancer. They provided policy solutions to increase the use of primary and secondary screening, including essential private bathroom access for colonoscopy preparation in patients who had a positive screening or who require surveillance after diagnosis and treatment. They concluded that increasing early detection and treatment may be cost-effective and could reduce disparities in morbidity and mortality in homeless patients.

Disparities in post-operative surveillance testing for metastatic recurrence among colorectal cancer survivors.
This population-based study assesses individual- and neighborhood-level factors associated with receipt of carcinoembryonic antigen (CEA) and computer tomography (CT) surveillance testing. Using SEER-Medicare data to identify beneficiaries diagnosed with colorectal cancer (CRC) stages II-III, they found that, overall, 78% and 58% of CRC survivors received CEA and CT testing, respectively. Further, Medicare-Medicaid dual coverage was associated with 39% lower odds of receipt of CEA tests among non-Hispanic Whites, while Blacks with dual coverage had almost two times the odds of receiving CEA tests compared to Blacks without dual coverage. Although this study did not find significant differences in receipt of initial CEA and CT surveillance testing across racial/ethnic groups, the assessment of the factors that measure access to care suggests differences in access to these procedures within racial/ethnic groups.

Aspirin use to prevent cardiovascular disease and colorectal cancer: updated evidence report and systematic review for the US Preventive Services Task Force.
This evidence summary reviewed the benefits and harms of aspirin in primary cardiovascular disease (CVD) and colorectal cancer (CRC) prevention to accompany the final recommendation and evidence review of the US Preventive Services Task Force. A literature review was conducted of English-language randomized clinical trials (RCTs) of low-dose aspirin compared with placebo or no intervention in primary prevention populations. Aspirin was found not to be significantly associated with reductions in CVD mortality or all-cause mortality. There was limited trial evidence on benefits for CRC, with the findings highly variable by length of follow-up and statistically significant only when considering long-term observational follow-up beyond randomized trial periods. Low-dose aspirin was associated with significant increases in total major bleeding and in site-specific bleeding.

Aspirin use to prevent cardiovascular disease and colorectal cancer: updated modeling study for the US Preventive Services Task Force.
The purpose of the study was to develop, model, and report estimates of the harms from and benefits of the use of low-dose aspirin for the prevention of cardiovascular disease (CVD) and colorectal cancer (CRC.) The researchers developed and used a simulation model to provide estimates for hypothetical United States cohorts of men and women between the ages of forty and seventy-nine years without a previous history of elevated bleeding risks or CVD, and up to a 20% 10-year risk for a CVD event. The model focused on the routine, lifetime use of low-dose aspirin with 5-year intervals of no use between 65 and 85 years of age. The study’s primary outcome was lifetime net benefit which was measured in life-years and quality-adjusted life-years (QALYs.) Harms included an increase in nonfatal intracranial hemorrhage and gastrointestinal bleeding, and benefits included a reduction in nonfatal ischemic stroke and myocardial infarction. The study found that the estimated lifetime net quality-adjusted life-years was positive for men and women with 5% or more 10-year CVD risk when they started use between the ages of 40-59 years, and for men and women with 10% or greater 10-year CVD risk when starting between the ages of 60 and 69 years. The estimated lifetime net life-years were mostly negative for those starting low-dose aspirin use between 60 and 79 years of age. Five-year intervals of stopping use between 65 and 85 years of age did not provide a significant advantage to lifetime use. The researchers concluded that the routine, lifetime use of low-dose aspirin may benefit several population groups, with the largest estimated benefit in those with greater 10-year CVD risk who begin routine, low-dose aspirin dosage at younger ages.

An observational study of workflows to support fecal testing for colorectal cancer screening in primary care practices serving Medicaid enrollees.
This study was conducted to describe clinical workflows for fecal immunochemical tests/fecal occult blood tests (FIT/FOBT) in Oregon primary care practices and to identify specific workflow processes that might be associated with higher colorectal cancer (CRC) screening rates. Findings showed that primary care practices with higher CRC screening rates among newly age-eligible Medicaid enrollees had more established visit-based and population outreach workflows to support identifying patients due for screening, FIT/FOBT distribution, reminders, and follow up. Higher CRC screening was associated with having medical assistants discuss and review FIT/FOBT screening and instructions with patients.

Reevaluating the evidence for intensive postoperative extracolonic surveillance for nonmetastatic colorectal cancer.
This study reevaluated the evidence for intensive postoperative extracolonic surveillance for nonmetastatic colorectal cancer. The authors looked at the FACS, GILDA, and COLOFOL trials and used a model to predict the large-sample mortality reduction expected for each trial and the implied statistical power. An investigation was done of a potential recurrence imbalance in the FACS trial. The model predicted a mortality reduction of ≤5% and power of <10% for all 3 trials. The FACS recurrence imbalance most likely led to a large relative bias (>2.5) in the hazard ratio for overall survival favoring control. After adjustment, both COLOFOL and FACS results were consistent with model predictions. A 2.6 and 3.6 month increase in life expectancy is predicted comparing intensive extracolonic surveillance-routine computed tomography scans and carcinoembryonic antigen assays with 1 computed tomography scan at 12 months or no surveillance, respectively. A larger trial that would randomize at least 200 to 300 patients is needed, but is not feasible at this time. The authors concluded recent trial results do not warrant de novo skepticism or metastasectomy nor targeted extracolonic surveillance.
