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

Winoker S, NOCR Proceedings, 20000

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
