Significance of perioperative blood transfusions in patients undergoing resection of stage I and II non-small-cell lung cancers

Perioperative blood transfusions (BT) have been reported to reduce survival in patients undergoing curative resection of lung cancers. It is postulated that a state of BT-mediated immunosuppression favors the proliferation of tumor cells not resected during surgery. To evaluate this hypothesis and to determine factors influencing the administration of BT, we retrospectively studied the charts of 127 patients who underwent surgery for stage I and II non-small-cell carcinoma. Thirty (23.6 percent) patients received BT and 97 (76.4 percent) did not. Sex, age, race, smoking history, size and stage of the tumor, histology, extent of resection and preoperative hemoglobin values were analyzed. Only age (p = 0.01) and preoperative hemoglobin values (p less than 0.01) were related to transfusion status. Neither survival nor event- free survival differed significantly between the two groups (p = 0.29 and 0.26 respectively). Our results do not support the hypothesis that perioperative BTs have a significant detrimental effect on survival. A prospective study could clarify this controversial issue; however, such a study would be complex considering the multiple variables that affect survival in patients with non-small-cell lung cancers.
