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 (P lt;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 (P lt;0.05), but there was no significant difference among different differentiation degrees (P gt;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.
