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.

Differences in pretreatment frailty across gastrointestinal cancers in older adults: results from the Cancer and Aging Resilience Evaluation registry.
The purpose of this study was to explore differences in pretreatment frailty between colorectal (CRC), hepatobiliary, and pancreatic cancers. The researchers included adults aged 60 years and higher enrolled in the Cancer and Aging Resilience Evaluation registry. A 44-item Cancer and Aging Resilience Evaluation frailty index was utilized to define frailty, which included geriatric assessment impairments of functional status, cognitive complaints, health-related quality of life, comorbidities, polypharmacy, anxiety, depression, malnutrition, falls, ability to walk one block, and interference in social activities. A total of 505 patients were included in the study: 41.8% with CRC, 35.2% with pancreatic cancer, and 116 23.0% with hepatobiliary cancer. The study found the following prevalence of frailty: 40.6% pancreatic, 34.3% hepatobiliary, and 23.3% CRC. Frailty was linked with higher rates of malnutrition and instrumental activities of daily living impairments in patients with pancreatic cancer and higher number of comorbidities in patients with hepatobiliary cancer. The study concluded that adults aged 60 and over with pancreatic and hepatobiliary cancers are at high-risk of pretreatment frailty.

An approach to the primary and secondary prevention of gastric cancer in the United States.
In 2020, a summit was convened at Stanford University to address the disparity of gastric cancer as a leading cause of mortality among certain racial, ethnic and immigrant groups in the United States, and the absence of a national strategy for addressing gastric cancer prevention. A working group was formed to conduct a structured literature review to critically evaluate the effectiveness, potential benefits, and potential harms of methods of primary and secondary prevention. The purpose of this article was to provide a consensus statement from that group. The authors found that the distribution of gastric cancer rates is highly inequitable and falls primarily on Asian, African American, Hispanic, and American Indian/Alaskan Native populations. The group concluded that there is an urgent need for cancer prevention trials in high-risk minority populations in the United States.

Magnesium intake is associated with a reduced risk of incident liver cancer, based on an analysis of the NIH-American Association of Retired Persons (NIH-AARP) Diet and Health Study prospective cohort.
Liver cancer incidence and mortality are escalating globally. Magnesium intake has been studied extensively in nonmalignant liver pathology, but the association between dietary intake of magnesium and primary liver malignancy has not been previously evaluated. In this study, investigators aimed to determine the association between total magnesium intake and primary liver cancer risk. The investigators concluded that based on their prospective cohort analysis, magnesium intake was associated with a lower risk of primary liver cancer, which was more pronounced among moderate and heavy alcohol users.

Endoscopy for gastric cancer screening is cost effective for Asian Americans in the United States.
Endoscopic screening for gastric cancer is routine in some countries with high incidence and is associated with reduced gastric cancer-related mortality. Immigrants from countries of high incidence to low incidence of gastric cancer retain their elevated risk, but no screening recommendations have been made for these groups in the United States. In this study the investigators aimed to determine the cost effectiveness of different endoscopic screening strategies for noncardia gastric cancer, compared with no screening, among Chinese, Filipino, Southeast Asian, Vietnamese, Korean, and Japanese Americans.

Population-based analysis of differences in gastric cancer incidence among races and ethnicities in individuals age 50 years and older.
There are racial and ethnic differences in the incidence of gastric adenocarcinoma worldwide and in the US. Based on a decision analysis, screening for noncardia gastric adenocarcinoma might be cost-effective for non-White individuals 50 years or older. In this study, the investigators aimed to estimate the differences in gastric adenocarcinoma incidence in specific anatomic sites among races and ethnicities in individuals 50 years or older.

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.

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.

Associations between calcium and magnesium intake and the risk of incident gastric cancer: a prospective cohort analysis of the National Institutes of Health-American Association of Retired Persons (NIH-AARP) Diet and Health Study.
Gastric cancer remains a leading cause of cancer-related mortality. Identifying dietary and other modifiable disease determinants has important implications for risk attenuation in susceptible individuals. The primary aim of the investigators was to estimate the association between dietary and supplemental intakes of calcium and magnesium and the risk of incident gastric cancer. They conducted a prospective cohort analysis of the National Institutes of Health-American Association of Retired Persons Diet and Health Study.

Occupational exposures and odds of gastric cancer: a StoP project consortium pooled analysis.
Gastric cancer pathogenesis represents a complex interaction of host genetic determinants, microbial virulence factors and environmental exposures. The primary aim of this study was to determine the association between occupations/occupational exposures and odds of gastric cancer. Based on a large pooled analysis, the investigators identified several occupations and related exposures that were associated with elevated odds of gastric cancer.

Increased incidence and mortality of gastric cancer in immigrant populations from high to low regions of incidence: a systematic review and meta-analysis.
Gastric cancer is the leading cause of infection-related cancer death and the third-leading cause of cancer death worldwide. The effect of immigration on gastric cancer risk is not well-defined but might be helpful for screening or surveillance endeavors. In this study, the authors performed a systematic review and meta-analysis to define the risk of gastric cancer in immigrants from high-incidence regions to low-incidence regions (including Western Europe, Australia, Brazil, Canada, Israel, and the United States).

Utilization of minimally invasive surgery and its association with chemotherapy for locally advanced gastric cancer.
This study compared outcomes of patients with T3 or greater and/or N+ gastric carcinoma who had minimally invasive surgery (MIS) or traditional open surgery. Patients who received MIS had a greater likelihood of receiving postoperative chemotherapy. Patients from the National Cancer Database (21,872) from 2010 to 2015 were identified. The majority (72.2%) received open surgery although MIS rates went up during that time period. Predictors of MIS were Asian race, any insurance coverage and treatment at high-volume centers. Survival rates were higher for MIS patients although that could be explained by their increased likelihood of receiving adjuvant chemotherapy.

Upper endoscopy up to 3 years prior to a diagnosis of gastric cancer is associated with lower stage of disease in a USA multiethnic urban population, a retrospective study.
This study focused on the feasibility of earlier diagnosis of non-cardia gastic cancer (NCGC) for high-risk populations in the US who include multiracial and ethnic populations. A retrospective study was conducted with patients who were positively identified endoscopically with NCGC at Mount Sinai Hospital in New York City. The primary outcome was an increased frequency of patients diagnosed with stage 0-Ia (38%) as opposed to stage Ib-III (34%) and stage IV (20.3%). For patients with stage 0-Ia if they had a prior negative endoscopy there was a 94% higher likelihood of the NCGC being in a curable stage.

The independent effect of cancer on outcomes: a potential limitation of surgical risk prediction.
This study aims to compare the use of common risk models for benign versus malignant gastrointestinal disease. It found that the National Surgical Quality Improvement Program (NSQIP) prediction models less effectively evaluate the risk of death in cancer patients as compared to patients with benign disease. A diagnosis of cancer is independently associated with an increased risk of surgical complications.
