Introduction: There is evidence for the prognostic value of perioperative blood transfusion in the surgical treatment of patients with rectal cancer in the current literature. Also preoperative anaemia seems to have an impact on the outcome of these patients. The aim of this study was to evaluate the impact of preoperative anaemia and perioperative blood transfusion in patients with rectal cancer treated in our hospital.
Patients and methods: 208 patients (81 females, 127 males; median age, 67 years) with rectal cancer were included in this retrospective study. All patients received surgical treatment. In 75 % of the patients an anterior rectum resection was performed while 25 % received an abdominoperineal rectum exstirpation. Patients with neoadjuvant treatment were included and statistical analyses were performed.
Results: 107 (51.4 %) patients exhibited preoperative anaemia. Patients with neoadjuvant treatment presented with significantly lower preoperative Hb (haemoglobin) values than patients without neoadjuvant treatment (p = 0.022). Patients with preoperative anaemia received significantly more blood transfusions (p = 0.001), had significantly longer hospital stays (p = 0.023) and significantly lower 5-years overall survival (p = 0.005). Blood transfusion was necessary in 82 patients (39.4 %). These patients presented with a significantly higher rate of perioperative complications (p = 0.01) and a lower 5-years overall survival (p = 0.002). In multivariate analyses neither preoperative anaemia nor perioperative transfusion was a significant prognostic factor.
Conclusion: In our study preoperative anaemia and perioperative blood transfusion seems to have an impact on outcome of surgical treatment of patients with rectal cancer. However, in multivariate analyses neither preoperative anaemia nor perioperative transfusion was a significant prognostic factor.
