Visceral Obesity, Metabolic Syndrome, and Esophageal Adenocarcinoma

Jessie A Elliott, John V Reynolds

Abstract

Esophageal adenocarcinoma (EAC) represents an exemplar of obesity-associated carcinogenesis, with a progressive increase in EAC risk with increased body mass index. In this context, there is increased focus on visceral adipose tissue and associated metabolic dysfunction, including hypertension, diabetes mellitus and hyperlipidemia, or combinations of these in the metabolic syndrome. Visceral obesity (VO) may promote EAC via both directly impacting on gastro-esophageal reflux disease and Barrett's esophagus, as well as via reflux-independent effects, involving adipokines, growth factors, insulin resistance, and the microbiome. In this review these pathways are explored, including the impact of VO on the tumor microenvironment, and on cancer outcomes. The current evidence-based literature regarding the role of dietary, lifestyle, pharmacologic and surgical interventions to modulate the risk of EAC is explored.

Liquid biopsy to diagnose esophageal adenocarcinoma

This impressive multicenter study by Miyoshi et al. introduces a new diagnostic tool named EMERALD, which is a six-circulating miRNA signature designed to effectively differentiate patients with esophageal adenocarcinoma (EAC) and its precursor, Barrett's esophagus (BE), from non-disease controls. The research involved analyzing 792 patient samples across four

Neoplastic progression in young Barrett's patients

Esophageal adenocarcinoma is quite rare among persons younger than 40 years, but the consequences of the disease, including years of life lost, can be devastating. Due to its rarity there has been little research on how risk factors in young persons (e.g., Barrett's esophagus (BE), obesity, GERD,

Diagnosis and management of GERD

While most adults occasionally experience symptoms of gastroesophageal reflux, such as heartburn and regurgitation, approximately 20% (30 million people in the U.S.) experience these symptoms more frequently, ranging from once a week to multiple times a day. (1) Complications associated with GERD can include esophageal strictures, ulcers, and even

Ethics of screening based on race/ethnicity

This article explores some of the ethical implications of using race and ethnicity for cancer screening, using esophageal adenocarcinoma and gastric cancer as examples. It highlights the disparities in cancer incidence and mortality among different racial and ethnic groups and examines the potential benefits and drawbacks of screening based (in
