Genetic variation in C20orf54, PLCE1 and MUC1 and the risk of upper gastrointestinal cancers in Caucasian populations.

ABSTRACT: Recently, two large genome-wide association studies, conducted in Chinese populations, have reported associations between upper gastrointestinal cancer and the rs2274223, rs13042395 and rs4072037 polymorphisms in PLCE1, C20orf54 and MUC1, respectively. We aimed to determine whether similar associations existed for Caucasian populations. We genotyped two population-based, case-control studies of upper gastrointestinal cancer; the first study included 290 gastric cancer (GC) cases and 376 controls and the second study included 306 GC cases, 107 oesophageal adenocarcinoma cancer cases, 52 oesphageal squamous cell cancer cases and 211 controls. Odds ratios (OR) and 95% confidence intervals (CIs) were computed from logistic models and adjusted for confounding variables. The rs4072037 polymorphism in MUC1 was associated with a reduced risk of GC of intestinal histological type (OR 0.4; 95% CI 0.2-0.9) and a reduced risk of oesophageal squamous cell cancer (OR 0.5; 95% CI 0.2-1.0), but not oesphageal adenocarcinoma. Similarly, rs2274223 in PLCE1 was associated with a reduced risk of oesophageal squamous cell cancer (OR 0.5; 95% CI 0.3-1.0), but not oesphageal adenocarcinoma. We observed no association between rs13042395 in Corf54 and the risk of gastric or oesphageal cancer in either of the two studies. Our findings for rs4072037 and the risk of GC are in agreement with one previous report for a Caucasian population. To the best of our knowledge, this is the first study to report an association between rs2274223 and rs4072037 and the risk of oesophageal squamous cell carcinoma in a Caucasian population.

Project description:PurposeThe Upper Gastrointestinal Cancer Registry (UGICR) was developed to monitor and improve the quality of care provided to patients with upper gastrointestinal cancers in Australia.ParticipantsIt supports four cancer modules: pancreatic, oesophagogastric, biliary and primary liver cancer. The pancreatic cancer (PC) module was the first module to be implemented, with others being established in a staged approach. Individuals are recruited to the registry if they are aged 18 years or older, have received care for their cancer at a participating public/private hospital or private clinic in Australia and do not opt out of participation.Findings to dateThe UGICR is governed by a multidisciplinary steering committee that provides clinical governance and oversees clinical working parties. The role of the working parties is to develop quality indicators based on best practice for each registry module, develop the minimum datasets and provide guidance in analysing and reporting of results. Data are captured from existing data sources (population-based cancer incidence registries, pathology databases and hospital-coded data) and manually from clinical records. Data collectors directly enter information into a secure web-based Research Electronic Data Capture (REDCap) data collection platform. The PC module began with a pilot phase, and subsequently, we used a formal modified Delphi consensus process to establish a core set of quality indicators for PC. The second module developed was the oesophagogastric cancer (OGC) module. Results of the 1?year pilot phases for PC and OGC modules are included in this cohort profile.Future plansThe UGICR will provide regular reports of risk-adjusted, benchmarked performance on a range of quality indicators that will highlight variations in care and clinical outcomes at a health service level. The registry has also been developed with the view to collect patient-reported outcomes (PROs), which will further add to our understanding of the care of patients with these cancers.
