Abstract:
Objective To investigate the expression of nm23-H1 in human benign and malignant colorectal lesions and the relationship between invasion,metastasis in colorectal carcinoma.Methods The expression of nm23-H1 were determined by ABC immunohistochemical technique in 80 cases human colorectal carcinoma,and compared with that in adenoma and normal mucus.Result Positivity expression rates of nm23-H1 were 66.7% in colorectal carcinoma.No significant difference of the expression of nm23-H1 in normal mucus,adenoma and cancerous tissue (P>0.05).The positive rates of nm23-H1 expression in different pathological grading,lymph node metastasis and post-operative survival (3 years) were showed significant difference (P<0.05).Conclusions It is suggested that the deletion of nm23-H1 low expression might play an important role in the carcinogenesis,development,metastasis and prognostic value of human colorectal carcinoma.
