Objective: To study the effects of platelet activation and endothelial cell injury on the patients with malignant tumor and their prognoses.Methods: Radioimmunity and ELISA methods were employed to detect the TXB2, GMP-140, vWF, cGMP and FN in 78 cases of malignant tumor and 40 healthy control persons.Results: The levels of TXB2, MP-140 and cGMP were increased in intestinal cancer group, lung cancer group and hepatic cancer group, while FN decreased in intestinal cancer and lung cancer group. cGMP was positively related to TXB2, GMP-140, vWF in malignant tumor group. FN was decreased in the group complicated with infection and the group with metastasis, while the other indexes increased. GMP-140, vWF and cGMP was decreased after operation except for the increasing of FN.Conclusion: Activations of platelet and injury of endothelial cells developed in patients with malignant tumor, and both of them affected the metastasis and prognosis of malignant tumor.
