Perioperative blood transfusions, with or without allogeneic leucocytes, relate to survival, not to cancer recurrence

Abstract

Leucocyte depletion of perioperative transfused blood has no effect on long-term survival and/or cancer recurrence. Perioperative blood transfusions are associated with impaired survival, but not with cancer recurrence. The slight increase in local recurrence rate in transfused patients appears to be related to complicated, in particular rectal, surgery.
