ABSTRACT
<p><b>OBJECTIVE</b>To investigate the expressions of homeobox transcription factor-2 (CDX(2)) and E-cadherin and their relations to the clinicopathological characteristics of gastric carcinoma.</p><p><b>METHODS</b>Immunohistochemistry was performed on 83 human gastric carcinoma specimens and 40 normal gastric mucosa specimens for examining the expressions of CDX(2) and E-cadherin, and the relations of their expression with the tumor differentiation, infiltration and metastasis were analyzed.</p><p><b>RESULTS</b>According to the LaurAn classification, the positive expression rate of CDX(2) in intestinal type of gastric carcinoma was 56.86%, and 34.38% in the diffuse type, showing significant difference between the two types (P<0.05). The positivity rate of E-cadherin was also significantly different between the two types (66.67% vs 28.13%, P<0.01). In regard to tumor differentiation, the positivity of CDX(2) and E-cadherin expressions was significantly different between moderately to well differentiated tumors and poorly differentiated ones (P<0.01). The tumors infiltrating mucosal and submucosal layers were significantly different from those infiltrating the muscular and serous membrane layer in the positivity of CDX(2) and E-cadherin expressions (P<0.01), which were also different for the presence of lymph node metastasis (P<0.05). Regression analysis did not reveal significant correlations between CDX(2) and E-cadherin expression in gastric carcinoma (P>0.05).</p><p><b>CONCLUSION</b>The abnormal expression of CDX(2) and E-cadherin plays an important role in the development of gastric carcinoma, especially the intestinal type. CDX(2) and E-cadherin may serve as useful markers to predict the prognosis of patients with gastric carcinoma.</p>
