Cancer patients with venous thromboembolism (VTE) have an increased incidence of bleeding complications while on anticoagulant therapy.


RIETE is an ongoing registry of consecutive patients with acute VTE. We tried to identify which cancer patients are at a higher risk for major bleeding.


Up to May 2009, 4,709 patients with active cancer had been enrolled in RIETE registry. During the first 3 months of anticoagulant therapy, 200 (4.2%) patients developed major bleeding. Then, 38 (0.8%) further patients bled beyond the first 90 days of therapy, 3 bled after withholding anticoagulant therapy. The most common sites of bleeding were the gastrointestinal tract (118 patients, 49%), genitourinary system (43 patients, 18%) and the brain (27 patients, 11%). In all, 160 patients (66%) died within 30 days after bleeding: 88 (55%) died of bleeding, 3 (1.9%) died of recurrent pulmonary embolism.


Major bleeding is a frequent and severe complication in cancer patients with VTE, even beyond the third month. One third of the patients who bled died due the bleeding event.
