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.

Patient-reported outcomes after external beam radiotherapy with low dose rate brachytherapy boost vs radical prostatectomy for localized prostate cancer: five-year results from a prospective comparative effectiveness study.
The purpose of this study was to compare patient reported outcomes through 5 years following radical prostatectomy or external beam radiation therapy with low dose rate brachytherapy boost for localized prostate cancer. The researchers enrolled men 80 years of age or under who had localized prostate adenocarcinoma and followed them longitudinally from 2011 to 2012. The study found that when compared with radical prostatectomy, external beam radiation therapy with low dose rate brachytherapy boost was related with clinically meaningful worse urinary irritative/obstructive and better urinary incontinence function through 5 years. Urinary function bother was similar between groups. Treatment with external beam radiation therapy with low dose rate brachytherapy boost was associated with worse bowel function through 5 years compared to radical prostatectomy. Treatment with external beam radiation therapy with low dose rate brachytherapy boost was associated with better sexual function at 1 year compared to radical prostatectomy, but there was insufficient evidence to reject the supposition that no difference was seen at 3 or 5 years. The researcher concluded that external beam radiation therapy with low dose rate brachytherapy boost was related with clinically meaningful worse urinary irritative/obstructive and bowel functions but better urinary incontinence function through 5 years after treatment compared to radical prostatectomy.

Hospital volume predicts guideline-concordant care in stage III esophageal cancer.
This study developed quality measures for management of stage III esophageal cancer including: utilization of neoadjuvant therapy, surgical sampling of at least 15 lymph nodes, resection within 60 days of chemotherapy or radiation, and completeness of resection to determine whether hospital volume varies measure adherence of published guidelines. A total of 1345 hospitals participating in the National Cancer Database from 2004 to 2016 were included. The authors examined association of volume, program accreditation, safety net status, geographic region, and patient travel distance on adequate adherence (≥85% of patients are adherent) using logistic regression modeling. The rate of adequate adherence was worst in nodal staging at 12.6% and highest for utilization of neoadjuvant therapy at 84.8%. Academic programs had the highest rate of adequate adherence for induction therapy (77.2%), timing of surgery (56.6%), and completeness of resection (78.5%) but lowest for nodal staging at only 4.4%. Every additional esophagectomy performed per year increased the odds of adequate adherence for induction therapy and completeness of resection but decreased for nodal staging.

Systematic review of the impact of a plant-based diet on prostate cancer incidence and outcomes.
The objective of this study was to perform a systematic review of plant-based diets and prostate cancer. Findings showed that interventional studies displayed generally favorable results of lifestyle modifications incorporating a plant-based diet with prostate cancer outcomes as well as improvements in nutrition and general health. Further, observational studies demonstrated either a lower risk of prostate cancer or no significant difference.

Vitamin and mineral supplements for the primary prevention of cardiovascular disease and cancer: updated evidence report and systematic review for the US Preventive Services Task Force.
This evidence report and systematic review updated the 2013 USPSTF final recommendation to assess benefits and harms of using vitamin and mineral supplements for the primary prevention of cardiovascular disease and cancer. After an extensive literature review, 84 studies were included. While multivitamin use was significantly associated with a lower incidence of any cancer and lung cancer, the evidence had serious limitations. Beta carotene was significantly associated with an increased risk of lung cancer and cardiovascular mortality. Vitamins D and E were not significantly associated with all-cause mortality, cardiovascular disease events, or cancer incidence. Evidence for the benefit of other supplements was equivocal, minimal, or absent. There was limited evidence that suggested some supplements may be associated with higher risk of serious harms (hip fracture [vitamin A], hemorrhagic stroke [vitamin E], and kidney stones [vitamin C, calcium]).

Patient navigator team perceptions on the implementation of a citywide breast cancer patient navigation protocol: a qualitative study.
This study’s goal was to assess the implementation of the 2018 Translating Research Into Practice (TRIP), an evidence-based patient navigation intervention aimed at addressing breast cancer care disparities, across six Boston hospitals. Patient navigator team member perspectives regarding implementation barriers and facilitators one-year post-study implementation were assessed. Seventeen interviews were conducted with patient navigators, patient navigator supervisors, and designated clinical champions. The following benefits were identified by participants: 1) increased networking and connections for navigators across clinical sites (Cosmopolitanism), 2) formalization of the patient navigation process (Goals and Purpose, Access to Knowledge and Information, and Relative Advantage), and 3) flexibility within the TRIP intervention that allowed for diversity in implementation and use of TRIP components across sites (Adaptability). Barriers included documentation requirements and the structured patient follow up guidelines that did not always align with the timeline of existing site navigation processes.

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.

Association between pelvic nodal radiotherapy and patient-reported functional outcomes through 5 years among men undergoing external-beam radiotherapy for prostate cancer: an assessment of the Comparative Effectiveness Analysis of Surgery and Radiation (C
In this study, the investigators sought to compare functional outcomes for men receiving prostate and pelvic versus prostate-only radiotherapy, longitudinally over 5 years. The investigators concluded that there were no clinically important differences in disease-specific or general health-related quality of life with the addition of pelvic irradiation to prostate radiotherapy, supporting the use of pelvic radiotherapy when it may be of clinical benefit, such as men with increased risk of nodal involvement.

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.

Contemporary prostate cancer radiation therapy in the United States: patterns of care and compliance with quality measures.
This study measured compliance with quality measures for radiation therapy treatment of prostate cancer. The Comparative Effectiveness Analysis of Surgery and Radiation Study enrolled men who were treated for localized prostate cancer from 2011 and 2012. Medical records were reviewed, and patients completed surveys. Researchers concluded that men who received external beam radiation therapy (EBRT) were treated more appropriately than those treated with brachytherapy (BT). White men were also more likely to receive appropriate treatment than African-American and other minorities.

Impact of concurrent medication use on pancreatic cancer survival-SEER-Medicare analysis.
Researchers examined the association of several medication classes on pancreatic cancer survival, using data from the Surveillance, Epidemiology, and End Results-Medicare database. They found that the use of beta-blockers, heparin, insulin, and warfarin were associated with improved survival in patients with pancreatic cancer, whereas metformin, thiazolidinedione, statin, and combination therapies were not. The authors recommended additional studies to validate these findings in the clinical setting.

Effect of prostate cancer severity on functional outcomes after localized treatment: comparative effectiveness analysis of surgery and radiation study results.
The purpose of this study was to determine whether differences in predicted function over time between radical prostatectomy (RP) or external beam radiotherapy (EBRT) for localized cancer varied by risk group. Patient-reported, disease-specific function was measured using the Expanded Prostate Index Composite and predicted function was estimated using regression models, compared by disease risk. The study found that sexual function was similar between surgery and radiation for patients with high-risk disease, and the authors conclude that high-risk patients undergoing radiation therapy should be counseled that their sexual function may not be as good as low-risk patients also undergoing radiation.

Behavioral counseling for skin cancer prevention: evidence report and systematic review for the US Preventive Services Task Force.
The authors systematically reviewed the evidence on the benefits and harms of behavioral counseling for skin cancer prevention to inform the US Preventive Services Task Force (USPSTF). They concluded that behavioral interventions can increase sun protection behavior, but there is no consistent evidence that interventions are associated with a reduction in the frequency of sunburn in children or adults and minimal evidence on skin cancer outcomes.
