An EST of a new given gene was obtained and might be useful in revealing the mechanisms of gastric signet ring cell carcinoma.

Metastasis rates of mucous adenocarcinoma and signet ring cell carcinoma are higher than those of well and mid differentiated carcinomas.

In the early gastric cancer, the rate of lymph node metastasis caused by signet ring cell carcinoma was not different from that of other gastric cancer.
