Thrombocytopenia and platelet transfusions in patients with cancer.
Platelet transfusions are a critical component of the supportive care for patients receiving intensive therapy for hematologic malignancies. The platelet count "triggering" prophylactic transfusion has decreased over the years, and studies comparing a prophylactic versus a therapeutic transfusion approach are in progress. The evidence supporting the need for platelet transfusions prior to different invasive procedures is reviewed. Lastly, studies evaluating the use of thrombopoietic stimulating agents to reduce hemorrhage and decrease the need for platelet transfusions are discussed. To date, there is no evidence that this approach is of clinical utility.
