The potential role of recombinant activated FVII in the management of critical hemato-oncological bleeding: a systematic review.

Recombinant activated factor VII (rFVIIa) is an hemostatic agent that was originally developed for the treatment of hemorrhage in patients with hemophilia and inhibitors. However, in the last few years rFVIIa has been employed with success in a broad spectrum of congenital and acquired bleeding conditions. In this systematic review we present the current knowledge on the use of this drug in patients suffering from hemato-oncological disorders, which are quite commonly complicated by severe hemorrhage. On the whole, data in the literature suggest a potential role for rFVIIa in the management of bleeding unresponsive to standard therapy in patients with hematological malignancies, including those undergoing bone marrow transplant. However, the vast majority of the currently available data are derived from uncontrolled studies including single cases or small series of patients. Thus, further trials with larger numbers of patients are needed to establish the most appropriate doses and timing of rFVIIa and to assess its efficacy and safety in this setting.
