Hyperglycaemia, hypercholesterolaemia and the risk for developing gastric dysplasia.
OBJECTIVE
Gastric dysplasia is believed to be the penultimate stage of gastric carcinogenesis. Few studies have evaluated whether there is a relationship between such risk factors and gastric dysplasia. This case-control study was conducted to investigate the associations between obesity, serum glucose, lipids and gastric dysplasia.


METHODS
Endoscopic findings and pathology specimens were reviewed from 1 July 1997 to 31 December 2006 in the Health Promotion Center. One hundred thirty patients have the dysplasia in the stomach during screening endoscopy. The same number of controls was evaluated and matched to the gastric dysplasia group for age and gender.


RESULTS
The univariate analysis showed that the dysplasia risk was slightly increased among persons with a higher low-density lipoprotein, lower high-density lipoprotein, impaired fasting glucose and higher total cholesterol. However, a higher body mass index and higher triglyceride level were not associated with the diagnosis of gastric dysplasia. In the multivariate-adjusted model, a higher low-density lipoprotein cholesterol and glucose were strongly associated with an increased risk of dysplasia compared to the controls. However, the body mass index, triglyceride and total cholesterol were not associated with the risk for dysplasia.


CONCLUSIONS
Hyperglycaemia and low-density lipoprotein cholesterol appear to be associated with the risk for gastric dysplasia. Further epidemiologic studies including a large cohort of patients with gastric dysplasia and adenocarcinoma are needed to clarify the association of low-density lipoprotein cholesterol, serum glucose and gastric carcinogenesis.
