Objective To investigate the expressions of CEACAM6 (CD66c) and MMP-9 in gastric cancer tissue and their relationship with tumor micro-angiogenesis. Methods Immunohistochemistry was used to detect the expressions of CEACAM6 and MMP-9
and microvessel density (MVD) in 54 samples of gastric cancer and 10 normal gastric tissue. The clinical data were retrospectively analyzed. Results The positive rates of CEACAM6 and MMP-9 in gastric carcinoma tissue were 85.19% (46/54) and 74.7% (40/54)
respectively
which were significantly higher than those in normal gastric tissue [30.00% (3/10)
20.00% (2/10)
respectively
P0.05]. The value of MVD in gastric cancer tissue was 32.17±8.97
which was significantly higher than that in normal gastric tissue (18.62±5.07
P0.05). The expression of CEACAM6 was associated significantly with depth of invasion and clinical stage of gastric cancer (P0.05)
but was not associated with gender
age
differentiation and lymph node metastasis (P0.05). The expression of MMP-9 and the value of MVD were associated significantly with depth of invasion
clinical stage
differentiation and lymph node metastasis of gastric cancer (P0.05)
but they had no relation with gender and age (P0.05). There was a significantly positive correlation between CEACAM6 expression and MMP-9 expression in gastric cancer tissue (r=0.593
P=0.000). The value of MVD in the individuals with positive expression of CEACAM6 or MMP-9 was significantly higher than that in the patients negative to CEACAM6 or MMP-9 (P0.05). Conclusion Moderate and strong expressions of MMP-9 and CEACAM6 in gastric cancer tissue are associated with tumor micro-angiogenesis
invasion and metastasis
which may contribute to the occurrence and development of gastric cancer.
