Objective To investigate the expression of Fascin-1 protein in colorectal adenocarcinoma, and the relationship with its clinicopathologic features. Methods The expressions of Fascin-1 protein in colorectal adenocarcinoma tissues of 60 cases, colorectal adenoma tissues of 30 cases and normal mucosa tissues (4 cm distance to neoplasm) of 30 cases were detected by Microwave-EliVisionTM immunohistochemistry method, and the relationship between the expression of Fascin-1 protein in colorectal adenocarcinoma tissues and its clinicopathologic characteristics was analyzed. Results The expression of Fascin-1 protein was located in cytoplasm. The positive expression rates of Facsin-1 protein were 3.3% (1/30), 30.0% (9/30) and 53.3% (32/60) in normal mucosa tissues, colorectal adenoma tissues and colorectal adenocarcinoma tissues, respectively. The expression of Fascin-1 was gradually increased in these three tissues, and there was statistical difference among the three tissues (Plt;0.05). The expessions of Fascin-1 protein in patients with serous membrane invasion, lymph node metastasis and TNM Ⅲ+Ⅳ were higher than those of non-serous membrane invasion, non-lymph node metastasis and TNM Ⅰ+Ⅱ (Plt;0.05), but there was no significant difference among different differentiation degrees (Pgt;0.05). Conclusion The high expression of Fascin-1 protein is correlated to high invasion ability and lymph node metastasis, which can play as a sensitive index in predicting the invasion and metastasis of colorectal adenocarcinoma.
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.
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 MicrowaveEliVisionTM immunohistochemistry, and the relationship with clinicopathologic features was analyzed. ResultsThe expressions of galectin3 protein and MVD in normal mucosa tissues, adenoma tissues, and cancer tissues gradually increased (Plt;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 (Plt;0.05， Plt;0.01), and the expression of glectin-3 protein was also correlated to differentiated degree (Plt;0.05). The expression of galectin-3 protein in colorectal cancer tissues was positively correlated to MVD (r=0.420， Plt;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.
