Management of Anemia in Cancer Patients: Transfusions

Anemia in cancer patients can be treated with transfusions, and 15% of patients with solid tumors are being treated by transfusions. Different cutoff values are used for transfusions, depending on clinical symptoms and patient characteristics, with a hemoglobin (Hb) level of <9 g/dL most commonly used. After the administration of one unit of red blood cells (RBC), the Hb rises with 1 g/dL, and the life span of transfused RBC is 100-110 days. Complications related to RBC transfusion are procedural problems, iron overload, viral and bacterial infections, and immune injury. RBC transfusions have been related to increased risk of the development of non-Hodgkin lymphoma and chronic lymphocytic leukemia, and are related to a worse treatment outcome in selected cancers. In addition, the cost of a transfusion for the patient and society is around 300-500 euros per unit transfused. RBC transfusions should be used carefully to correct anemia in patients with cancer.
