Abstract

Background Multiple myeloma (MM) is characterized by an increased incidence of thromboembolic events, especially when immunomodulatory drugs are used. Currently, our ability to predict these thrombotic events is limited. We hypothesized that global coagulation tests may be predictive of thrombotic events in MM patients. Methods Blood samples were taken from 36 MM patients before and during routine treatment. Thrombin generation (TG) tests including endogenous thrombin potential (ETP) and peak height were analyzed. Results Patients were followed for a median of 2.5 years. Those who developed thrombotic events were characterized by significantly higher ETP and peak height values compared to those who did not (P = 0.001). In these patients, we identified a gradual increase in TG parameters that preceded the thrombotic event. Anticoagulation therapy was associated with a significant decrease in ETP and peak height values (P < 0.001). There was no statistically significant difference in TG parameters between newly diagnosed MM patients and healthy subjects, as well as between MM patients prior to and during chemotherapy. Conclusions TG tests might predict thrombotic events in MM patients. Thus, TG tests may be incorporated into decision-making protocols of prophylactic anticoagulant therapy in MM patients.
