Risk of thromboembolic events associated with different multiple myeloma regimens in Taiwan: a nested case-control study

J Thromb Thrombolysis. 2023 Sep 22. doi: 10.1007/s11239-023-02887-7. Online ahead of print.ABSTRACTAlthough novel agents for multiple myeloma (MM) have a better response rate and survival in both newly diagnosed and relapsed/refractory MM patients, concerns regarding the association between MM treatments and thromboembolic events have been raised. The aim of this population-based study was to examine the association between different combinations of MM treatments and the risk of thromboembolic events. We conducted a nested case-control study using the Taiwan Cancer Registry (TCR) and National Health Insurance Research Database (NHIRD). Adult patients newly diagnosed with MM and treated with at least one of the immunomodulatory agents between 2008 and 2016 were identified. Among them, we further identified patients who developed thromboembolic events as cases and selected controls matched by age, sex and duration of MM diagnosis at a ratio of 1:5. The index date was defined as the day one year before the diagnosis date of thromboembolic events in the case group and the corresponding date in the control group. Conditional logistic regression was used to examine the association between different MM treatment regimens and the risk of thromboembolic events. A total of 4,180 newly diagnosed MM patients treated with at least one of the immunomodulatory agents were identified (mean age: 67.2 years; male: 55.7%). In this MM cohort, we further identified 388 cases and 1,940 matched con...
