Influence of perioperative whole blood transfusions on lymphocyte subpopulations in patients with stage II breast cancer

Noninfectious complications of blood transfusion

CONTEXT

Serious noninfectious complications are far more likely to occur than viral disease transmission from blood component transfusion.

OBJECTIVE

To compile a comprehensive list of the noninfectious risks of transfusion, examples of published risk estimates, and summaries of recent information regarding cause, prevention, or management of noninfectious transfusion risks.

DATA SOURCES

Information was obtained from peer-reviewed English-language medical journal publications since 1990.

CONCLUSIONS

Early complications, although potentially more serious, usually occur less frequently (<1 in 1000 transfusions) than late complications, which often affect more than 1% of recipients. Areas of active investigation and discussion include acute hemolytic reactions, transfusion-related acute lung injury, red cell alloimmunization, platelet transfusion refractoriness, and transfusion immunosuppression. Continued effort toward research and education to promote recognition and prevention of noninfectious complications associated with blood components is warranted.

Prognosis and postoperative lymphocyte count in patients with hepatocellular carcinoma who received intraoperative allogenic blood transfusion: a retrospective study

AIMS

The effect of perioperative blood transfusion on the survival of hepatocellular carcinoma (HCC) has not been fully investigated. To clarify the prognostic value of intraoperative allogenic blood transfusion, we conducted a comparative retrospective analysis of 224 patients with HCC who underwent hepatic resection.

METHODS

We compared clinicopathologic background and survival after hepatic resection between patients who received intraoperative blood transfusion (n=101) and those who did not (n=123).

RESULTS

Patients with blood transfusion had a larger tumor and more frequent vascular invasion than those without blood transfusion. The 5-year cancer-related survival rate after hepatic resection, but not the disease-free survival rate, was significantly lower in patients who underwent blood transfusion than in those who did not (38.3% vs. 66.7%, P<0.01). Multivariate analysis showed intraoperative blood transfusion (P=0.02), microscopic portal invasion (P<0.01), and preoperative serum alpha-fetoprotein elevation (P=0.03) to be independent risk factors for poor outcome after hepatic resection. The negative effect of blood transfusion on postoperative survival was observed only in patients with a tumor larger than 50mm in diameter. The absolute peripheral blood lymphocyte count on postoperative day 1 was significantly lower in patients who underwent blood transfusion (880/mm(3)) than in those who did not (1081/mm(3)) (P<0.01).

CONCLUSIONS

Our data suggest that intraoperative blood transfusion results in immunosuppression in the early postoperative period, allowing for progression of residual HCC after resection. Therefore, intraoperative allogenic blood transfusion should be avoided in patients with resectable HCC, particularly in those with a large tumor.
