Abstract

Oesophageal adenocarcinoma is one of the most fatal tumours to affect the digestive tract and is the eighth most common malignancy worldwide. Gastro-oesophageal reflux has an important role in the incidence of adenocarcinoma of the oesophagus. Gastro-oesophageal reflux disease (GERD) is a multifactorial, acid-peptic disorder that results from the reflux of noxious material from the stomach into the oesophagus. The refluxed material causes the occurrence of oesophageal inflammation which creates a condition that is called reflux oesophagitis. The prevalence of this disease has increased dramatically in recent decades, mostly in the western world, where it affects about 10% to 30% of the population. The aetiology of oesophageal mucosal damage is complicated. Many inflammatory mediators are produced within the gastrointestinal (GI) tract, but their contributions in pathophysiology and disease pathogenesis have not been well investigated. Despite the protective barrier provided by the oesophageal mucosa, refluxed materials can cause oxidative injury and in?ammatory responses that involve the epithelium and immune cells. The analysing cellular events in gastro- oesophageal reflux disease and physiological responses to such conditions are important and necessary for a better grasp of the pathogenesis of GERD and the expansion of new treatments. Therefore, we want to discuss some of the important and key factors of GERD disease in this article.

Keywords: COX; GERD; HIF; MPO; cytokines; inflammatory factors; oesophagitis.
