BACKGROUND Metallothionein 3 (MT3) inhibits growth in a variety of cell types. We measured MT3 gene expression by RT-PCR, and DNA methylation in the MT3 promoter by combined bisulphite restriction analysis, in four oesophageal cancer cell lines and the resected oesophagus from 64 patients with oesophageal squamous cell carcinoma (SCC). RESULTS MT3(More)
Oesophageal adenocarcinoma (EAC) incidence is rapidly increasing in Western countries. A better understanding of EAC underpins efforts to improve early detection and treatment outcomes. While large EAC exome sequencing efforts to date have found recurrent loss-of-function mutations, oncogenic driving events have been underrepresented. Here we use a(More)
BACKGROUND Minimally invasive esophagectomy (MIE) compared with open esophagectomy (OE) has been shown to have clinical advantages, but selection bias is present. METHODS All patients undergoing MIE or OE for cancer between 1999 and 2007 were eligible for analysis. To minimize selection bias, only patients who also met the selection criteria for the(More)
To identify novel non-invasive biomarkers for improved detection, risk assessment and prognostic evaluation of cancer, expression profiles of circulating microRNAs are currently under evaluation. Circulating microRNAs are highly promising candidates in this context, as they present some key characteristics for cancer biomarkers: they are tissue-specific(More)
Esophageal adenocarcinoma (EAC) has become a major concern in Western countries due to rapid rises in incidence coupled with very poor survival rates. One of the key risk factors for the development of this cancer is the presence of Barrett's esophagus (BE), which is believed to form in response to repeated gastro-esophageal reflux. In this study we(More)
Patients diagnosed with esophageal adenocarcinoma (EAC) or gastroesophageal junction adenocarcinoma (GEJAC) have poor survival. We investigated the possible influence of pre-morbid lifestyle factors on survival for these lethal cancers. This study included a population-based cohort of patients with EAC (n = 362) and GEJAC (n = 421) tumors. Detailed(More)
BACKGROUND Previous research suggests that females have a poorer outcome than do males after surgery for gastroesophageal reflux. OBJECTIVE To evaluate reflux and esophageal symptoms in males and females in a community sample and in patients undergoing antireflux surgery. DESIGN Face-to-face interview. SETTING A South Australian community. (More)
BACKGROUND Ulceration of the oesophageal squamous mucosa (ulcerative oesophagitis) is a pathological manifestation of gastro-oesophageal reflux disease, and is a major risk factor for the development of Barrett's oesophagus. Barrett's oesophagus is characterised by replacement of reflux-damaged oesophageal squamous epithelium with a columnar intestinal-like(More)
The polymerase chain reaction amplifies and quantifies small amounts of DNA. It is a cyclic process, during each cycle of which each strand of template DNA is copied with probability approaching one: the amount of DNA approximately doubles and this amount can be estimated fluorimetrically each cycle, producing a set of fluorescence values hereafter referred(More)
OBJECTIVES To determine if histopathologic assessment of esophageal biopsies harvested for research study is justified due to the heterogeneity of tissues in the esophagus, and the consequent histopathologic mis-matches with the clinical histopathology of biopsies taken at the same level. METHODS Since 2004, patients undergoing upper endoscopy for a(More)
