Blood transfusion and survival in colorectal cancer

Abstract

Purpose: This study examined the effect of blood transfusion on the prognosis of patients undergoing surgery for colorectal cancer.

Methods: Potentially curative resections for colorectal cancer were performed in 266 patients who were followed prospectively, with a minimum follow-up of 41 months. They were divided into transfused (n = 121) and nontransfused (n = 145) groups according to their perioperative blood transfusion requirements.

Results: There were significantly more rectal tumors (chi 2 = 9.5, df = 1, P = 0.002) and fixed tumors (chi 2 = 4.5, df = 1, P = 0.03) in the transfused group. There was no statistically significant difference between the two groups with regard to recurrence-free survival (chi 2 = 1.1, df = 1, P = 0.3) and overall survival (chi 2 = 2.8, df = 1, P = 0.09).

Conclusion: In this study we have found no statistically significant effect of perioperative blood transfusion on the prognosis of colorectal cancer patients.
