DVT in MM
• Incidence of DVT in MM per se
vs drug-related (IMiDs, Dex, Chemo)
• How does Dex fit into DVT risk?
• How about other drugs?
– Anthracyclines + thalidomide or lenalidomide
• Intensity of anti-coagulation
– ASA vs warfarin vs LMWH
Incidence and Prophylaxis of Thrombosis With
Thalidomide-Based Therapies
Rajkumar SV, et al. Mayo Clin Proc. 2005;80:1549-1551.
Lenalidomide:
Thrombotic Events
Len / dex
(n = 346)
Placebo / dex
(n = 345)
Thrombotic Events 12% 4%
DVT 8% 3%
PE 3% 1%
DVT = deep vein thrombosis; PE = pulmonary embolism.
• 3 deaths due to thromboembolic events
• Prophylactic anticoagulation was not required in these studies

Role of Bortezomib in
Preventing Thrombosis
• Reduction of thrombotic risk observed in
randomized trials
• Mechanism unclear (endothelial effects? Effect on
platelet aggregation?)
• Bortezomib + lenalidomide or thalidomide +/- Dex
(RVD, VTD) now a therapeutic backbone in MM with
low rates of thrombosis (5%)

Summary and Conclusion
• Prevention of DVT / PE a key priority
• Newly diagnosed vs relapsed MM
• Risk evaluation
• Choice of combination therapy
• Appropriate prophylaxis
– Aspirin, warfarin, LMWH
