Cancer and Thromboembolism
Armand Trousseau (1801-1867)
In cancer patients migrant thromboembolic events are
common.It was first recognized by Armand
Trousseau in 1865 as ‘’Phlegmacia alba dolens’’.
Dr. Trousseau died because of gastric cancer in 1867.
Thromboembolism in Lung Cancer
• The incidence of DVT in lung cancer is about 10-15%
• In the patients who developed DVT previously;– The possibility of recurrent DVT increases– The risk of death caused by acute thrombosis
increases 4-6 times.– The aspect of survival shortens as compared
to the cancer patients without DVT.
Concurrent VTE and cancer increases the risk of death
Probability of death within 183 days of initial hospital admission

Patients with cancer assosiation
• 24% have pancreatic cancer
• 20% have lung cancer
• 13% have prostate cancer
• 12% have gastric cancer
• 5% have colon cancer
• Patients with stage IV disease are more likely to be hypercoagulable and develop clinically relevant thrombosis

Risk factors for VTE in cancer
Patient related•Increasing age•Obesity•Immobility•Inhereted thrombophilic abnormalities
Cancer related•Histological type•Stage•Anatomic location
Treatment related•Surgical intervention•Type of chemotherapy or biologic treatment•Central venous access devices
Under use of Prophylaxis
• 66 % of patients at risk DID NOT receive prophylaxis
• 60 % of patients at very high risk with multiple risk factors DID NOT receive prophylaxis

Thromboprophylaxis for the lung cancer patients
• Primary prophylaxis
• Secondary prophylaxis
( recurrent VTE )
Common strategies considered for prophylaxis: do they work ?
• Ambulation
• Mechanical devices
• Unfractionated heparin
• Low molecular weight heparin
• Warfarin

Surgical Prophylaxis
LMWH better UFH better
7th ACCP Consensus Guidelines
Grade Recommendation for Cancer Patients
1APatients undergoing surgery should receive LDUH 5000 U tid or LMWH high risk dose once daily
2APatients undergoing surgery may receive post-hospital discharge prophylaxis with LMWH
Medical Patients
1APatients hospitalised with an acute medical illness should receive LDUH or LMWH
Geerts W, et al. Chest 2004; 126: 338S-400S.
Thromboprophylaxis for patients undergoing cancer surgery
• Give LDUH or LMWH 2 hours before surgery.• Optimal duration of thromboprophylaxis remains
the subject of debate. 7-10 days? 7-8 weeks?• The risk of spinal hematoma with neuroaxial
anesthesia may be acceptable.• When pharmacologic prophylaxis is used in
conjunction with mechanical prophylaxis the efficacy appears to increase.
Leonardii Mj, Ann Surg Oncol 2006Berqvist D, J Surg Oncol, 2007
Catheter-Related Thrombosis
• Low dose warfarin and LMWH prophylaxis have fared to show any reduction in symptomatic catheter-related thrombosis.
• Low dose warfarin is associated with an increase in bleeding.
• The risk of symptomatic catheter-related thrombosis in adults is low (about 5 %)
• Optimal prevention of CRT remains unclear.

7th ACCP Consensus Guidelines
Grade Recommendation for Cancer Patients
1AFor most patients with DVT and cancer, we recommend treatment with LMWH for at least the first 3 – 6 months of long-term treatment.
Buller et al. Chest 2004; 126: 401S-428S.
DVT Prophylaxis
• Physical methods:– Intermittent Pneumatic Leg Compression
(Venodynes)– Early ambulation– Compression stockings
• Pharmacological methods– Unfractionated heparin– LMWH– Warfarin
Prophylaxis Recommendations
Category Recommendation
Moderate RiskGeneral Abd, Thoracic, gyn, uro surg; medical pts
IPC, +/- heparin/LMWH based on other RF
Moderate to High RiskNeurosurgery IPC
High RiskHip/knee replacement IPC, LMWH, +/- warfarin
Hip fracture IPC, LMWH, warfarin
Spinal cord injury w/ paralysis LMWH, IPC
Long Term Anticoagulation
• 3-6 months:– First episode with
reversible or time limited RF (i.e. bed rest) –
• >= 6 months– Idiopathic first episode
• 12 months– First recurrent DVT
• Lifetime– First event with
• Cancer, until resolved• Anticardiolipin Ab• ATIII deficiency
– 2 or more recurrent DVTs
Conclusion
• Most pts who die from PE, die within 2 hours of onset, prior to implementation of treatment– THUS PREVENTION IS KEY
