Cancer-associated Thrombosis The first report was published by the French physician Jean-BaptisteBouillaud in 1823
Cancer-associated Thrombosis Widely quoted description by Armand Trousseau in 1865 Trousseau’s Syndrome migratory thrombophlebitis associated with an occult visceral malignancy
Outline • History • Epidemiology • Pathogenesis • Thromboprophylaxis
Epidemiology • About 20% - 30% of venous thromboembolism (VTE)are cancer- associated • Cancer patients have a 4 to 7-fold increased risk of VTE compared with the general population 【Blood 2013 122: 1712-1723】
Type of Cancer VS. Risk of VTE 【Blood 2013 122: 1712-1723】
Later stage of cancer, higher risk of VTE 【Blood 2013 122: 1712-1723】
Cancer with VTE in Taiwan • 497,180 cancer patients, between 1997 to 2005, with a median follow-up of 21.3 months • Incidence: 185 events per 100,000 person-years • 11.5 times higher than the general population 【ThrombHaemost 2012; 108: 225–235】

1 【Blood 2007 110: 1723-1729】
Mucin • Trousseau’s syndrome associated with mucin-producing carcinomas • Glycosylated secretory products of epithelial cells • ligands for the selectins
Selectin (P-selectin and L-selectin) 【J. Clin. Invest. 112:853–862 (2003)】
2 【Blood 2007 110: 1723-1729】
Tissue Factor (TF) • TF-rich tumor surface and TF-positive, Tumor-derived microparticle • Correlation between elevated TF and VTE
TF-positive, Tumor-derived Microparticle (TMP) Phosphatidylserine negatively-charged phospholipids Selectinligand 【Blood. 2013;122(11):1873-1880】
3 【Blood 2007 110: 1723-1729】
Cysteine Proteinase • directly activated factor X in the absence of factor VII
4 【Blood 2007 110: 1723-1729】
Tumor Hypoxia • increase the expression of genes that facilitate coagulation, including tissue factor and plasminogen activator inhibitor type 1 (PAI-1)
5 【Blood 2007 110: 1723-1729】
Oncogene Activation • MET oncogene involve up-regulation of PAI-1 and cyclooxygenase-2 (COX-2) genes

Conclusions • Cancer increased risk of VTE, especially advanced stage • The pathogenesis included mucin, tissue factor, and others • VTE increased mortality • Thromboprophylaxis is an issue, especially in high risk group
