Identification of underlying and transfusion-related platelet qualitative alterations in the hemato-oncologic patient.

Hemato-oncologic patients with chemotherapy-induced thrombocytopenia are one of the populations receiving platelet transfusions. The general practice with these patients is to give prophylactic platelet transfusions when platelet counts fall below 10×10PLT/L. However, in more than 40% of these patients, platelet transfusion does not prevent bleeding.
