摘要
Abstract
Purpose To investigate the expression of tumor metastasis suppressor gene-1 (TMSG-1) in colorectal cancer tissues and liver metastases,and to analyses the relationship between expression of TMSG-1 and clinicopathologic characteristics. Methods Immunohistochemical SP methods was used to detect the expression of TMSG-1 protein in 200 cases of colorectal cancer and 52 cases of liver metastases. Results The ratio of high,moderate and negative of TMSG-1 expression in primary colorectal carcinoma were 42. 5％ (85/200) ,29. 5％ (59/200) and 28. 0％ (56/200) respectively. The expression of TMSG-1 was significantly associated with tumor differentiation, invasion depth,lymph node metastasis,distant metastasis and TNM stages (P < 0. 05) ,but unrelate to age,gender and tumor size. The high, moderate and negative expression ratio of TMSG-1 in liver metastases were 17. 3％ (9/52) ,50. 0％ (26/52) ,32. 7％(17/52) ,respectively. The expression of TMSG-1 in liver metastases was significantly lower than that in primary lesion (P < 0. 05) . The expression of TMSG-1 in liver metastases, and there was no significant correlation between the expression of TMSG-1 in liver metastases and clinicopathologic characteristics. Conclusion The expression of TMSG-1 is significantly down-regulated in the liver metastases,which is associated with the development and progression of colorectal cancer. TMSG-1 will be used as a new tumor marker for predicting the prognosis of colorectal cancer.关键词
