The frequency of red cell transfusion for anemia in patients receiving chemotherapy. A retrospective cohort study

The objective of this retrospective cohort study was to determine the frequency of red cell transfusion for anemia and risk factors. It was conducted at a regional cancer center and host hospital. All patients receiving chemotherapy in 1989 were studied. Complete data were available on 381; 26 were excluded. Age, diagnosis, baseline and nadir hemoglobin, transfusion history, chemotherapy regimen, and prior treatment were abstracted from the cancer center chart and hospital medical records. Transfusion for anemia was required in 18% of all patients with solid tumors; those with lung cancer had the highest rate (34%). Patients with anemia who entered chemotherapy were more likely to be transfused. Therefore, patients with leukemia, lung cancer, and/or prior anemia have higher transfusion rates and may benefit from such therapies as recombinant human erythropoietin.
