Abstract:
Objective : To study the expression and role of heparanase mRNA in colorectal carcinoma.
Methods : The expression of heparanase mRNA by ISH in 45 cases colorectal carcinoma was detected.
Results : There were 22 cases with heparanase mRNA positive staining in 45 cases of colorectal carcinoma, the positive rate was 48.88%. The increased expression of heparanase mRNA was observed in 26 cases of colorectal carcinoma with lymph node metastasis compared to those without metastasis(P<0.01). Heparanase mRNA expression related to lymph node metastasis and depth of serosal invasion in colorectal carcinoma.
Conclusion : Heparanase may play a definite role in the growth,invasion and metastasis in colorectal carcinoma.
