ObjectiveTo explore the expressions of galectin-3 protein and CD105 protein in colorectal cancer and the relationship with clinicopathologic features. MethodsThe expressions of galectin-3 protein and CD105 protein 〔microvessel density (MVD)〕 were detected in 60 cases of colorectal cancer tissues, 30 cases of adenoma tissues, and 30 cases of normal mucosa tissues (at least 4 cm far from carcinoma) by MicrowaveEliVisionTM immunohistochemistry, and the relationship with clinicopathologic features was analyzed. ResultsThe expressions of galectin3 protein and MVD in normal mucosa tissues, adenoma tissues, and cancer tissues gradually increased (P lt;0.05). The expression of galectin-3 protein and MVD in colorectal cancer tissues were correlated to TNM stage, invasive depth, and lymph node metastasis (P lt;0.05, P lt;0.01), and the expression of glectin-3 protein was also correlated to differentiated degree (P lt;0.05). The expression of galectin-3 protein in colorectal cancer tissues was positively correlated to MVD (r=0.420, P lt;0.01). ConclusionsThe high expressions of galectin-3 protein and CD105 protein are correlated to the high invasion ability and lymph node metastasis, which may be potential sensitive index to predict the invasion and metastasis of colorectal cancer.
