[Component transfusion in cancer chemotherapy--platelet transfusion and granulocyte transfusion]

The role of component transfusion has become important in cancer chemotherapy. Recently, it has become possible to obtain large amounts of platelets and granulocytes by the mechanical development of continuous flow centrifugation or filtration leukopheresis. These methods have enhanced the clinical efficiency of platelet transfusion. Although, several reports of randomized controlled studies of granulocyte transfusion have been published, its effectiveness has not yet been clearly established.
