Assessment of Fibrinolytic Activity in Gastric Cancer

Abstract

Objectives: To explore the relationship between thrombin-antithrombin complex (TAT), plasmin—α plasmin inhibitor complex (PIC), thrombomodulin (TM), tissue plasminogen activator/plasminogen activator inhibitor-1 complex (t-PAIC) and Gastric cancer. Methods: The plasma levels of TAT, TM, t-PAIC and PIC in patients with gastric cancer (40 in the initial diagnosis group and 35 in the post-treatment group) and 40 healthy controls were measured by chemiluminescent enzyme immunoassay. Then analyze the differences between these indicators in different stages of gastric cancer patients and healthy controls. Results: 1) The plasma levels of TAT, TM, t-PAIC and PIC in the newly diagnosed gastric cancer group were higher than those in the control group and the post-treatment group (P 0.05). 2) The plasma levels of TAT, TM, t-PAIC and PIC were not significantly different among the effective treatment group, the ineffective treatment group and the healthy control group. Conclusion: The changes of TAT, TM, t-PAIC and PIC levels are closely related to the development of patients with gastric cancer, and their increase may indicate that patients have a high risk of thrombosis.
