Abstract:
Objective To evaluate the significance of carbohydrate antigen 50 (CA50) expression in colorectal carcinoma. Methods Immunohistochemical staining was used to detect CA50 expression in 10 cases of normal colorectal mucosa and 40 cases of cancer mucosa. Results The expression of CA50 increased in normal colorectal mucosa, cancer distant mucosa, cancer adjacent mucosa and cancer mucosa, and there were significant differences among them (P<0.05). The expression of CA50 in colorectal carcinoma was correlated with the degree of differentiation, Duke's stage and lymphatic metastases (P<0.05). Conclusion The expression of CA50 can be used as a valuable index in evaluating the biological characteristics and prognosis of colorectal carcinoma.
