Esophageal resection for cancer (EC) is still associated with considerable mortality and morbidity rates. Allogenic blood transfusion (aBT) is associated with poor short-term and long-term outcome in surgical oncology. We aimed to evaluate the effect of aBT in a homogeneous population of EC patients undergoing esophagectomy without perioperative treatment.
We analyzed 565 esophagectomies performed due to EC. Allogenic blood transfusion was correlated to clinicopathological parameters, perioperative mortality and morbidity as well as the long-term outcome. Results are presented as adjusted odds ratio (OR) or hazard ratio (HR) with 95 % confidence interval (95 % CI).
Patients receiving aBT (aBT(+)) had no higher tumor stages or higher rates of lymph node metastasis (P = 0.65 and 0.17, respectively) compared to patients without aBT (aBT(−)). Allogenic blood transfusion was strongly associated with perioperative morbidity (OR 1.9, 95 % CI 1.1–3.5, P = 0.02) and mortality (OR 2.9, 95 % CI 1.0–8.6, P = 0.04). Tumor recurrence rate was significantly higher in aBT(+) patients (P = 0.001). The disease-free and overall survival were significantly longer in aBT(−) compared to aBT(+) patients (P = 0.016 and <0.001, respectively). Patients receiving aBT had almost doubled risk for tumor recurrence (HR 1.8, 95 % CI 1.2–2.5, P = 0.001) and death (HR 2.2, 95 % CI 1.5–3.2, P < 0.001).
Allogenic blood transfusion has a significant impact on the natural course of EC after complete resection. The poor short-term and long-term outcome warrants further evaluation of the underlying molecular mechanisms induced by allogenic blood transfusion in cancer patients.
