Relationship between blood transfusion and cancer is considered from five points of view: 1) The cancer patient as a blood donor. Cancer must remain a cause of exclusion from blood donation. 2) Autologous blood transfusion for cancer patients. Predeposited autologous blood transfusion is only possible for a small number of patients. Intraoperative blood salvage carries with it the risk of disseminating tumor cells. 3) History of blood transfusion and the risk of having a cancer: a) the persistence of immune alterations following blood transfusion for years might expose the patient to an increased risk of having a cancer; b) blood transfusion might carry immunosuppressive viruses, and hepatitis viruses are related to the risk of liver cancer. 4) Cancer recurrence and blood transfusion. Conclusion of most of the published studies is that blood transfusion is associated with an increased risk of recurrence of colorectal cancer. The only realistic randomized study would compare different transfusion strategies (allogenic, leukocyte poor allogenic and autologous blood transfusion) to determine which is the best for cancer patients. 5) Post-transfusion GVH in cancer patients. Some cases have recently been published. They all can be explained by a particular HLA compatibility between the recipient and one of the blood donors.

Viral hepatitis is the third most common cause of liver disease in allogeneic transplant recipients and causes significant morbidity and mortality. When treating patients with hematological malignancies, an emphasis should be placed on identification of patients at risk for viral hepatitis with appropriate screening. Initial screening serology should include anti-HCV, HBsAg, anti-HBs, and anti-HBc testing. When hepatitis B exposure has been documented, prophylaxis of viral reactivation for all HBsAg-positive patients with a nucleoside analogue should be implemented. HCV infection appears to have little short-term impact on survival after bone marrow transplantation, but is a risk factor for veno-occlusive disease (VOD) and graft-versus-host disease (GVHD). In the long-term survivor, HCV infection can lead to significant morbidity and mortality due to the development of cirrhosis, decompensation, and liver cancer. Since effective antiviral therapies are available for both hepatitis B and C, routine screening and selected intervention is recommended once reactivation and disease recurrence is documented. In this chapter we will highlight the mechanisms of virus reactivation, clinical manifestations, and management strategies to minimize acute and chronic morbidity in this population.

Graft versus host disease (GVHD) is an uncommon complication following liver transplantation. In the present case report, a 53-year-old male hepatitis B virus carrier was diagnosed with primary liver cancer with post-hepatitis cirrhosis. Preoperative cytomegalovirus (CMV), Epstein-Barr virus, coxsackievirus, herpes simplex virus and autoimmune antibody series were negative. Preoperative human leukocyte antigen type was also negative. Following classic orthotropic liver transplantation, postoperative treatment included immunosuppression therapy, infection protection, anti-human immunodeficiency virus therapy and CMV infection protection therapy. Chemotherapy was initiated at day 16 following surgery. At day 26 following the transplantation, the patient developed a fever of unknown cause, and a scattered red rash was observed behind the left ear and on the neck. The patient presented with a fever of unknown cause, rash, symptoms of the digestive tract, leukocytopenia and pancytopenia. A diagnosis of GVHD was confirmed following a skin biopsy. Symptomatic therapies, including antivirals, anti-anaphylaxis drugs and steroids were administered. However, the patient succumbed to infection, acute respiratory distress syndrome and multiple organ failure at day 46 following surgery. Therefore, an effective therapeutic strategy for the treatment of GVHD following liver transplantation is yet to be established, and further research is required prior to such a regimen being developed.
