About

Malignant tumors are closely related to deep vein thrombosis, Pulmonary embolism and other diseases. Tumor patients usually have a hypercoagulable state (HCS) in their blood, and the proportion of thrombosis caused by HCS is more than 10 times that of non tumor patients. Conventional clinical testing methods such as coagulation function, blood routine, and thromboelastography are difficult to directly evaluate the hypercoagulable state of tumor patients. In addition, the widely used Khorana score and Caprini score systems in clinical practice need to be improved in accurately reflecting the hypercoagulable state of tumor patients.

Our team has established a complete new coagulation time measurement system, including general clotting time (GCT), platelet rich plasma clotting time (PRP-CT), and platelet poor plasma clotting time (PPP-CT), which may be a new and accurate method for evaluating tumor hypercoagulability.

The GCT study aims to evaluate: 1. The time of GCT, PRP-CT, and PPP-CT for malignant tumors is shorter than that of normal individuals, and some patients are in a hypercoagulable state; 2. The shortened time of GCT, PRP-CT, and PPP-CT may be associated with future thrombosis; 3. Evaluating the relationship between shortened GCT system time and overall tumor survival

Therefore, the GCT system evaluation may identify patients who are truly in a hypercoagulable state, providing monitoring indicators for subsequent anticoagulation; It can also be evaluated whether GCT time can reflect the prognosis of tumor patients.
