    Abstract:
    BACKGROUND/AIMS: To assess retrospectively the impact of perioperative blood transfusions on disease-free interval after curative surgery of rectal cancer. METHODOLOGY: One hundred and seven (107) subjects (65 men and 42 women, median age: 67) underwent anterior resection of the rectum for rectal cancer between 1990 and 1996. Thirty-six (37%) were transfused perioperatively. Outcome variables measured were: age, sex, distance of the tumor from the anal verge, type of stapled anastomosis, protective colostomy, cancer-free margin in the specimen, grading and staging, leak of the suture line, transfusion, number of blood units given, and adjuvant therapy. RESULTS: Transfusion, nodes involvement and adjuvant therapy had a significant impact on disease-free interval at the univariate analysis. The estimated probability of cancer-free survival at 5 years was 81% for the not transfused, and 63% for the transfused patients (P < 0.05). At multivariate analysis, nodes involvement resulted significantly and independently related to time to recurrence (P < 0.05) but also perioperative blood transfusion showed an important role as independent risk factor for rectal cancer relapse (P = 0.05). CONCLUSIONS: This study suggests that blood transfusion is likely to have a detrimental effect on disease-free interval after resective surgery of rectal cancer.
