Impact of blood salvage therapy during oncologic liver surgeries on allogenic transfusion events, survival, and recurrence: an ambidirectional cohort study.

Introduction: The use of autologous blood transfusions in oncologic surgeries is somewhat controversial due to the potential risk of disease dissemination through the salvage process. On the other hand, autologous blood transfusion can prevent the potential negative effects of allogenic blood transfusions and reduce use of valuable resources.

Methods: This study included 106 adult patients who underwent oncologic liver surgery at our institution between December 2015 and June 2019.
