Leptin and the risk of Barrett's oesophagus

Abstract

BACKGROUND: Obesity is associated with increased risks of Barrett's oesophagus and oesophageal adenocarcinoma. Alterations in serum leptin and adiponectin, obesity-related cytokines, have been linked with several cancers and have been postulated as potential mediators of obesity-related carcinogenesis; however, the relationship with Barrett's oesophagus remains unexplored. METHODS: Serum leptin and adiponectin concentrations were measured on two subsets of participants within a case-control study conducted in Brisbane, Australia. Cases were people aged 18-79 years with histologically confirmed Barrett's oesophagus newly diagnosed between 2003 and 2006. Population controls, frequency matched ..
