Objective To explore the expressions of Galectin-3, Fascin-1, and β-catenin protein in colorectal adenocarcinoma and the relations to clinicopathologic characteristics. Methods The expressions of Galectin-3, Fascin-1, and β-catenin protein were detected in 60 cases of colorectal adenocarcinoma, 30 cases of adenoma, and 30 cases of normal mucosa by microwave-EliVisionTM immunohistochemistry method, and analyzed the expressions of them and the relations to clinicopathologic characteristics. Results The expression rate of Galectin-3, Fascin-1, and β-catenin protein in CRC was 68.3% （41/60）, 53.3% （32/60）, and 81.7% （49/60） respectively, which was 46.7% （14/30）, 30.0% （9/30）, and 43.3% （13/30） respectively in adenoma, and 20.0% （6/30）, 3.3% （1/30）, and 13.3% （4/30） respectively in normal mucosa, the differences had statistical significance （P＜0.05）. The expressions of Galectin-3, Fascin-1, and β-catenin protein had statistically significant correlation with the TNM stage, invasive degree, and lymph node metastasis of colorectal adenocarcinoma （P＜0.05, P＜0.01）. The expressions of Galectin-3 and β-catenin protein had statistically significant correlation with the different differentiation degree of colorectal adenocarcinoma （P＜0.05）, but the expression of Fascin-1 protein was not related to differentiation degree of colorectal adenocarcinoma （P＞0.05）.The expressions of Galectin-3, Fascin-1, and β-catenin protein had not statistically significant correlation with the patient’s age and gender, and tumour size （P＞0.05）.There were positive correlations between the Galectin-3 and Fascin-1 or β-catenin （r=0.728，P＜0.01；r=0.696，P＜0.01）, and there was positive correlation between β-catenin and Fascin-1 （r=0.507，P＜0.01）. Conclusions The high expressions of Galectin-3, Fascin-1, and β-catenin protein in colorectal adenocarcinoma tissues are some extent correlated to the high invasive ability and lymph node metastasis, which could be used for the indexes to predict the invasion and metastasis in colorectal carcinoma potentially.
