title: Perioperative blood transfusion and recurrence and death after resection for cancer of the colon and rectum.
abstract: Several reports have claimed that perioperative blood transfusion promotes recurrence and death after cancer surgery. We studied the effect of transfusion in 315 patients who had radical resection for carcinoma of the colon and rectum. The disease recurred in 113 (42%) of 268 transfused patients, versus in 15 (32%) in 47 non-transfused patients (P = 0.2). Of the transfused patients 102 (38%) died of colon cancer, versus 13 patients (28%) in the non-transfused group (P = 0.2). The 5-year recurrence-free survival rate was 0.59 in the transfused patients and 0.72 in the non-transfused group (P = 0.10). When differences in confounding background variables were accounted for by Cox multiple regression analysis, the significance of transfusion was even less. The study does not support the hypothesis that perioperative blood transfusion promotes recurrence after operation for colorectal cancer.
