NCT01100814

Brief 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 non EBV-associated GC.

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.
