Purpose To assess whether perioperative allogenic blood transfusions in patients undergoing surgical treatment for spinal metastases independently influence patient survival. Methods A retrospective study including 170 consecutive patients undergoing surgical treatment for spinal metastases in 2009 and 2010 at a tertiary referral center. Variables related to postoperative survival were all included in the same multivariable logistic regression analysis with either 3- or 12-month survival as the dependent variable. The independent variables were: transfusion of allogenic red blood cells, age at surgery, gender, preoperative hemoglobin, revised Tokuhashi score and no. of instrumented levels. Results Perioperative allogenic blood transfusion of 1- units was associated with increased 12-month survival [p?=?0.049, odds ratio 2.619 (confidence interval 1.004-.831)], but not with 3-month survival. Larger transfusion volumes did not significantly influence survival. Conclusion The results of the present study support that perioperative blood transfusion of
