title: Preliminary study suggests low incidence of gastric carcinoma in kelantan relates to low rate of helicobacter pylori infection.
abstract: Helicobacter pylori-associated gastric carcinoma is generally more common in the antrum/body and is of the intestinal type. The aim of this study was to determine the pattern of gastric carcinoma in an area known to have a low prevalence of H. pylori. Pathology records of gastric carcinoma diagnosed at Hospital University Sains Malaysia between 1995 and 1999 were retrieved and studied. There were a total of 23 cases. The median age was 60 years. Eighteen patients were Malay and 5 were Chinese. The most common location of the tumour was the cardia/gastrooesophageal junction (61%, 14/23 patients). The majority was of the intestinal type (69.6%, 16/23). The frequency of gastric carcinoma appears to be exceptionally low in the area of study. The Chinese population was over-represented. The higher frequency of tumour in the cardia/gastro-oesophageal junction as compared to the antrum and body is in sharp contrast to most other studies. This reaffirms the notion that Helicobacter pylori infection is a causative agent for non-cardia gastric carcinomas.
