Expression of S100A2 and Trefoil Factor Family Members in Epstein-Barr Virus Related Gastric Cancer
An observational study of Gastric Cancer, run by National University Hospital, Singapore at 1 site in Singapore.
Trial summary
The investigators hypothesize that aberrant hypermethylation of tumour suppressor genes is an important mechanism for Epstein-Barr Virus (EBV) - related gastric carcinogenesis, the promoter hypermethylation status and the expression of S100A2 and TFF1 might be different between EBV-associated gastric cancer (GC) and… Read more about this study

Study population: 200 gastric tumour and normal tissue samples, as well as up to 50 non-neoplastic gastric tissues samples from individuals without gastric cancer (treated for other reasons, such as gastric ulcers) will be obtained from the tissue archives of the NUH Department of Pathology. These samples were selected because relevant clinical information of these samples are available from gastric database and will allow us to perform association studies.
