Improvement in Prediction of Blood Clots in Cancer Patients
WASHINGTON, Sept. 9 /PRNewswire-USNewswire/ -- For cancer patients, who have an increased risk of developing venous thromboembolism (VTE) due to a hyperactive blood coagulation system, there is now an enhanced risk model to predict their chance of developing blood clots, according to a recent study published today in Blood, the journal of the American Society of Hematology. VTE, the formation of blood clots in the veins, develops in up to 20 percent of cancer patients and is one of the leading causes of death among this patient population. Patients with hematologic malignancies (blood cancers), particularly those with lymphoma and multiple myeloma, have relatively high rates of VTE—results from this study found that 7.2 percent of lymphoma patients and 7.4 percent of the total study population developed VTE, compared to an estimated general population incidence rate of .001 percent(1)
"Because the risk of VTE is not equal in all cancer patients and anticoagulation in cancer patients results in a higher risk of bleeding complications, categorizing cancer patients according to their VTE risk is important," said Ingrid Pabinger, MD, professor at the Medical University of Vienna and lead author of the study. Patients with high risk of VTE may benefit from routine thrombophrophylaxis, preventive treatment for blood clotting, while low-risk patients tend to have a higher bleeding risk and may not be the best candidates for routine anticoagulation treatments.
Although there is a current risk prediction model for VTE in cancer patients, which includes factors such as site of cancer, body mass index, platelet and leukocyte counts, and hemoglobin level—all known to increase the risk of cancer-associated VTE—the new model also incorporates two new biomarkers, soluble P-selectin (sP-selectin) and D-dimer, to further stratify patients in
