The study was recently published in the journal "Blood Advances". VTE includes deep vein thrombosis (DVT), a blood clot that typically forms in the deep veins of the leg, and pulmonary embolism (PE), a life-threatening condition that occurs when a blood clot breaks free and lodges in the pulmonary arteries of the lungs. Although these blood clots can affect anyone, existing research suggests that people with a blood type other than O have a higher risk of developing VTE. Cancer and cancer treatments also increase the risk of blood clots. While thrombosis risk can be more accurately determined in people with cancers that have a high baseline risk, less research has been done on thrombosis risk in patients with cancers that are less commonly associated with blood clots. Blood typing as a predictive tool In the study, researchers led by Cihan Ay from the Division of Hematology and Hemastaseology (Department of Medicine I at MedUni Vienna and University Hospital Vienna) investigated the role of non-O blood groups in a subject's likelihood of developing VTE.
