Caution advised with perioperative transfusion in rectal cancer; leaves open whether it independently worsens survival.
Does perioperative blood transfusion affect survival and sVEGF concentrations in patients operated on for primary colorectal cancer?
Perioperative blood transfusion is associated with poor survival in patients with Dukes stage A, B, and C rectal cancers, and preoperative transfusion is associated with higher sVEGF concentrations.
K. Werther (2001) studied this question.
