Kang R, et al. – Given the limited data supporting the assumption that autologous transfusion is unsafe in major oncologic surgery due to a theoretic risk of spreading metastatic disease, researchers retrospectively analyzed 147 patients who underwent partial hepatectomy for colorectal cancer metastases at a single institution to assess the validity of this assumption. A total of 74 patients received autologous transfusion and 73 received no transfusion. Outcomes revealed no association of autologous blood transfusion with an increased recurrence risk or a higher mortality rate. Hence, the researchers indicated transfusing filtered autologous blood to be safe for patients undergoing liver resections for colorectal cancer metastases.
