Clinical significance of expression of livin and cyclin D1 in chronic atrophic gastritis with intestinal metaplasia

AIM: To investigate the expression of livin and cyclinD1 in chronic atrophic gastritis with intestinal metaplasia.

METHODS: Immunohistochemistry was used to examine the expression of livin and cyclin D1 in 30 cases of chronic superficial gastritis, 35 cases of atrophic gastritis without intestinal metaplasia, 35 cases of atrophic gastritis with intestinal metaplasia, and 30 cases of gastric carcinoma. We also explored the correlation between livin and cyclin D1 expression in chronic atrophic gastritis and gastric carcinoma.

RESULTS: The positive rates of livin expression in the specimens of chronic superficial gastritis, atrophic gastritis without intestinal metaplasia, atrophic gastritis with intestinal metaplasia, and gastric carcinoma were 0%, 28.57%, 45.71% and 66.67%, respectively, and the corresponding rates for cyclin D1 expression were 10%, 14.29%, 37.14% and 53.33%. The positive rates of livin and cyclinD1 expression were significantly higher in atrophic gastritis with intestinal metaplasia than in chronic superficial gastritis (both P < 0.05). The expression of cyclin D1 differed significantly between atrophic gastritis with and without intestinal metaplasia (P < 0.05). The expression of livin has a positive correlation with that of cyclin D1 in atrophic gastritis with intestinal metaplasia and gastric carcinoma.

CONCLUSION: The positive rates of livin and cyclin D1 expression increase in atrophic gastritis with intestinal metaplasia and gastric carcinoma. No significant difference was observed for the expression of livin and cyclin D1 between atrophic gastritis with intestinal metaplasia and gastric carcinoma. Livin and cyclin D1 may play a very important role in the development of gastric carcinoma and be used as markers for early diagnosis of gastric carcinoma.
