Abstract:
Objective Studing the relationship among matrixmetal-loproteinnse2 (MMP2), the tissue inhibitors of metalloprotein-ase2 (TIMP2) and chnicopathological characteristics such as histological grade, clinicopathological stage of the rectal cancer. Assessing the significance of MMP2 and TIMP2 expression in rec-tal cancer for prognosis and treatment. Methods To test the expression level of MMP2 and TIMP2 in rectal caneer patients with immunohistochemisty method. Results were analysised with χ2 test. The Kaplan-Meier (Log-rank test) was used for univariate survival analysis. Results The positive rates of MMP2 and T1MP2 ex-pression in rectal cance are higher in comparison with normal tissues. With MMP2 have a trendence of increas-ing the positive expression of TIMP2 decreases. Conclusion MMP2 and TIMP2 relate obviously with the clini-copathological character of the rectal cancer. They may play an important role in the proliferation, invasion and of the cancer. Testing the level of expression of MMP2 and TIMP2 may be helpful to prejudge the prognosis of the patients with rectal cancer. Some new therapic methods relating to MMP2 and TIMP2 may give patients with rectal cancer a more satisfying treatment.
