Abstract:
Objective To explore the common factors' influence on serum gastrin level,and reveal the value of serum gastrin in the diagnosis of gastric precancerous lesions and gastric cancers.Methods Serum gastrin level of 3 906 serum samples was detected by ELISA.Results Serum gastrin level of patients over 60 years old was distinctively higher than that of other age groups.Serum gastrin level in antral diseases was higher than that in diseases of the body.HP positive group was higher than the negative one.The level progressingly increased from normal group to superficial gastritis and to gastric erosion or ulcer;and it decreased from gastric erosion or ulcer to atrophic gastritis,while it increased from atrophic gastritis to dysplasia,and it decreased from dysplasia to gastric cancer.Serum gastrin level was distinctively lower in gastric cancer than in other groups.Conclusion For people over 60 years old,their serum gastrin level has the tendence to increase.The location of gastric disease is an important factor affecting serum gastrin level.HP can increase the serum gastrin level.During gastric precancerous stage,the serum gastrin level may gradually increase with the diseases' progression,and decrease when gastric cancer is formed.Serum gastrin is a good marker to differentiate benign and malignant gastric diseases.
