Methods: CB and MVD were detected by immunohistochemistry in 47 cases of colorectal carcinoma. Results: The expression of CB in mucinous colorectal carcinoma was significantly higher than that in no-mucinous colorectal carcinoma. There was significant difference (P<0.05). The MVD in group with positive CB was stronger than that in group with negative CB. There was also significant difference (P<0.05). Conclusion: The results suggest that CB expression has correlation with MVD, invasion and metastasis in colorectal carcinoma, especially in mucinous colorectal carcinoma.展开更多
