Thrombosis and cancer: emerging data for the practicing oncologist.

The American Society of Clinical Oncology (ASCO) recently updated clinical practice guidelines on the treatment and prevention of venous thromboembolism (VTE) in patients with cancer. Although several new studies have been reported, many questions remain about the close relationship between VTE and malignant disease. The risk of VTE among patients with cancer continues to increase and is clearly linked to patient-, disease- and treatment-specific factors. In general, VTE among patients with cancer is treated in a similar fashion to that in other patient populations. However, the greater risk of VTE in patients with cancer, the multitude of risk factors, and the greater risk of VTE recurrence and mortality among patients with cancer pose important challenges for surgeons, oncologists, and other providers.
