Abstract
AIM: To detect the expression of mucin-1 and mucin-2 in gastritis, intestinal metaplasia and gastric cancer.
METHODS: Thirty patients with gastritis (without intestinal metaplasia), thirty patients with intestinal metaplasia and forty-eight patients with gastric cancer, who were treated at our hospital from November 2011 to April 2012, were enrolled in this study. The expression of mucin-1 and mucin-2 in different types of gastric lesions was determined by immunohistochemistry.
RESULTS: The expression of mucin-1 in intestinal metaplasia was lower than that in gastritis (P > 0.05), but the expression of mucin-2 in intestinal metaplasia was higher than that in gastritis (P < 0.05). The rate of Helicobacter pylori (H. pylori) infection in intestinal metaplasia was higher than that in gastritis (P > 0.05). The expression of mucin-1 in gastric cancer was higher than that in intestinal metaplasia (P > 0.05), but the expression of mucin-2 in gastric cancer was lower than that in intestinal metaplasia (P < 0.05). The rate of H. pylori infection in gastric cancer was lower than that in intestinal metaplasia (P < 0.05). The expression of mucin-1 in gastric cancer was lower than that in gastritis (P > 0.05), but the expression of mucin-2 in gastric cancer was higher than that in gastritis (P < 0.05). The rate of H. pylori infection in gastric cancer was lower than that in gastritis (P > 0.05).
CONCLUSION: The expression of mucin-1 is down-regulated in the evolution of gastric cancer; however, the expression of mucin-2 is positive only in precancerous lesions and gastric cancer. This finding suggests that mucin-2 may be more closely related to the occurrence of gastric cancer. There is a negative correlation between expression of mucin-1 and H. pylori infection, but a positive correlation between mucin-2 expression and H. pylori infection.
