Uri Ladabaum, Ajitha Mannalithara, Joel V Brill, Zachary Levin, M Kate Bundorf
OBJECTIVES: Most cost-effectiveness analyses of colorectal cancer (CRC) screening assume Medicare payment rates and a lifetime horizon. Our aims were to examine the implications of differential payment levels and time horizons for commercial insurers vs. Medicare on the cost-effectiveness of CRC screening. METHODS: We used our validated Markov cohort simulation of CRC screening in the average risk US population to examine CRC screening at ages 50-64 under commercial insurance, and at ages 65-80 under Medicare, using a health-care sector perspective...

BACKGROUND AND AIMS: Endoscopists who encounter an interval colorectal cancer (I-CRC) may be concerned about the implications because I-CRCs may represent a lapse in colonoscopy quality and a missed opportunity for prevention. To determine the I-CRC rate per colonoscopy examination and to examine the effect of colonoscopy volume and adenoma detection rate (ADR) on the number of I-CRCs attributable to an endoscopist. METHODS: We determined the rate of I-CRC diagnosis per outpatient colonoscopy examination by measuring the incidence of CRC diagnosis in practice and by assessing, via literature review, the percentage of cancers that are interval...

Research on the communication of genetic test results has focused predominately on non-Hispanic White (NHW) mutation-positive families with high-risk hereditary cancer conditions. Little is known about this process for racially and ethnically diverse individuals or for those with mutations in moderate risk genes. The communication behaviors of study participants who carry a gene mutation were analyzed 3 months after disclosure of genetic test results. Participants were queried about communication of their results, as part of a prospective study of multi-gene panel genetic testing...

Importance: There have been substantial improvements in the early detection, treatment, and survival from cancer in the United States, but it is not clear to what extent patients with different types of health insurance have benefitted from these advancements. Objective: To examine trends in cancer survival by health insurance status from January 1997 to December 2014. Design, Setting, and Participants: California Cancer Registry (a statewide cancer surveillance system) data were used to estimate population-based survival by health insurance status in 3 calendar periods: January 1997 to December 2002, January 2003 to December 2008, and January 2009 to December 2014 with follow-up through 2014...

Purpose Racial/ethnic disparities in cancer survival in the United States are well documented, but the underlying causes are not well understood. We quantified the contribution of tumor, treatment, hospital, sociodemographic, and neighborhood factors to racial/ethnic survival disparities in California. Materials and Methods California Cancer Registry data were used to estimate population-based cancer-specific survival for patients diagnosed with breast, prostate, colorectal, or lung cancer between 2000 and 2013 for each racial/ethnic group (non-Hispanic black, Hispanic, Asian American and Pacific Islander, and separately each for Chinese, Japanese, and Filipino) compared with non-Hispanic whites...

BACKGROUND: The full spectrum of serious non-gastrointestinal post-colonoscopy complications has not been well characterized. We analyzed rates of and factors associated with adverse post-colonoscopy gastrointestinal (GI) and non-gastrointestinal events (cardiovascular, pulmonary, or infectious) attributable to screening or surveillance colonoscopy (S-colo) and non-screening or non-surveillance colonoscopy (NS-colo). METHODS: We performed a population-based study of colonoscopy complications using databases from California hospital-owned and nonhospital-owned ambulatory facilities, emergency departments, and hospitals from January 1, 2005 through December 31, 2011...

BACKGROUND: Although cancer screening reduces morbidity and mortality, millions of people worldwide remain unscreened. Social media provide a unique platform to understand public sentiment toward tools that are commonly used for cancer screening. OBJECTIVE: The objective of our study was to examine public sentiment toward colonoscopy, mammography, and Pap smear and how this sentiment spreads by analyzing discourse on Twitter. METHODS: In this observational study, we classified 32,847 tweets (online postings on Twitter) related to colonoscopy, mammography, or Pap smears using a naive Bayes algorithm as containing positive, negative, or neutral sentiment...

BACKGROUND AND AIMS: The 6-minute withdrawal time for colonoscopy, widely considered the standard of care, is controversial. The skill and technique of endoscopists may be as important as, or more important than, withdrawal time for adenoma detection. It is unclear whether a shorter withdrawal time with good technique yields an acceptable lesion detection rate. Our objective was to evaluate a 3-minute versus a 6-minute withdrawal time by using segmental tandem colonoscopy. METHODS: We performed a prospective, randomized trial by using 4 expert endoscopists...

Importance: Colorectal cancer (CRC) is the second-leading cause of cancer death in the United States. Screening can reduce CRC mortality and incidence, and numerous screening options, although available, complicate informed decision making. This review provides evidence-based tools for primary care physicians to identify patients with higher-than-average-risk and engage patients in informed decision making about CRC screening options. Observations: Recently, the US Preventive Services Task Force recommended any of 8 CRC screening approaches for average-risk individuals, beginning at age 50 years...

BACKGROUND & AIMS: The incidence of colorectal cancer (CRC) is increasing in the United States among adults younger than the age of 50 years. Studies of young-onset CRC have focused on outcomes and treatment patterns. We examined patient presentation, provider evaluation, and time to diagnosis, which can affect stage and prognosis. METHODS: In a retrospective study, we collected data from patients with a diagnosis of colorectal adenocarcinoma, confirmed by pathologists, seen at the Stanford Cancer Institute from January 1, 2008, through December 31, 2014...

Uri Ladabaum, Ajitha Mannalithara
BACKGROUND & AIMS: We developed a model to determine whether a multitarget stool DNA (MT-sDNA) test that detects colorectal cancer (CRC) and polyps with higher sensitivity and lower specificity, but at a higher cost, than the fecal immunochemical test (FIT) can be used in screening. METHODS: We used a Markov model of average-risk CRC screening to compare the effectiveness and cost effectiveness of screening with the MT-sDNA test vs FIT or colonoscopy. We accounted for the complex longitudinal participation patterns observed in organized programs vs opportunistic screening, as well as organized programs' patient support costs and differential payment rates by commercial insurers vs Medicare...

Persons with a family history (FH) of colorectal cancer (CRC) or adenomas that are not due to known hereditary syndromes have an increased risk for CRC. An understanding of these risks, screening recommendations, and screening behaviors can inform strategies for reducing the CRC burden in these families. A comprehensive review of the literature published within the past 10 years has been performed to assess what is known about cancer risk, screening guidelines, adherence and barriers to screening, and effective interventions in persons with an FH of CRC and to identify FH tools used to identify these individuals and inform care...

BACKGROUND: Tailoring screening to colorectal cancer (CRC) risk could improve screening effectiveness. Most CRCs arise from advanced neoplasia (AN) that dwells for years. To date, no available colorectal neoplasia risk score has been validated externally in a diverse population. The authors explored whether the National Cancer Institute (NCI) CRC risk-assessment tool, which was developed to predict future CRC risk, could predict current AN prevalence in a diverse population, thereby allowing its use in risk stratification for screening...

OBJECTIVES: Gastric intestinal metaplasia and dysplasia are precursor lesions for adenocarcinoma. The risks of progression to malignancy from these lesions are not well characterized, particularly in the US populations. METHODS: We identified 4,331 Kaiser Permanente Northern California members who were diagnosed with gastric intestinal metaplasia or dysplasia between 1997 and 2006 and followed them through December 2013. The incident rates of gastric adenocarcinoma, relative risks in comparison with the Kaiser Permanente general population, and predictors of progression to malignancy were investigated...

OBJECTIVES: Seventy percent of patients with irritable bowel syndrome (IBS) identify certain foods as triggers for their symptom flare-ups. To help identify potential trigger foods, practitioners often rely on patient food and gastrointestinal (GI) symptom journaling. The aim of the study was to evaluate the feasibility and usability of a novel food and symptom journal app, specifically designed for patients with IBS. Secondary aims were to explore the effect of using the app on GI symptoms and to describe associations between diet and GI symptoms suggested by individual patient data...
