Abstract
|
|
|
1. Intestinal and diffuse type gastric cancer have different age and sex distribution, and secular trend.
2. No clear differences in dietary factors was found between intestinal type and diffuse type gastric cancer, although, in a few studies, intestinal type was more related to specific dietary factors than diffuse type.
3. Both the intestinal and diffuse types of gastric cancer were associated with H. pylori infection. But strength of association with H. pylori in intestinal and diffuse types was controversial.
4. No differences in genetic polymorphism (CYP2E1, GSTM1, L-myc) was observed between two types of gastric cancer. Blood type A is more frequent in diffuse type (49%) than in intestinal type (39%) .
