The incidence of oesophageal adenocarcinoma (OAC) is increasing. At present, OAC is the 7th leading cause of cancer deaths worldwide. The use of aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs) reduce the progression from Barrett’s oesophagus (BO) to OAC. These cyclooxygenase (COX) targeted agents have demonstrated considerable promise, although long-term use has been associated with both gastrointestinal (GI) damage and increased cardiovascular risk. COX-2 overexpression is seen in BO and OAC patients and is a promising target for chemopreventive and/or therapeutic approaches. However, the unfavourable safety profile associated with long-term COX-2 targeting emphasizes the need to both understand and target specific downstream effector mechanisms. The role of pro-inflammatory prostaglandin E2 (PGE2) and its corresponding EP receptors have gained considerable att.. View More»
