PURPOSE: To investigate the effect of recombinant human erythropoietin (epoetin beta) on anemia, transfusion need, and quality of life (QOL) in severely anemic patients with low-grade non-Hodgkin's lymphoma (NHL), chronic lymphocytic leukemia (CLL), or multiple myeloma (MM).
PATIENTS AND METHODS: Transfusion-dependent patients with NHL (n = 106), CLL (n = 126), or MM (n = 117) and a low serum erythropoietin concentration were randomized to receive epoetin beta 150 IU/kg or placebo subcutaneously three times a week for 16 weeks. Primary efficacy criteria were transfusion-free and transfusion- and severe anemia-free survival (hemoglobin [Hb] > 8.5 g/dL) between weeks 5 to 16. Response was defined as an increase in Hb > or = 2 g/dL with elimination of transfusion need. QOL was assessed by the Functional Assessment of Cancer Therapy scale.
RESULTS: Transfusion-free (P =.0012) survival and transfusion- and severe anemia-free survival (P =.0001) were significantly greater in the epoetin beta group versus placebo (Wald chi(2) test), giving a relative risk reduction of 43% and 51%, respectively. The response rate was 67% and 27% in the epoetin beta versus the placebo group, respectively (P <.0001). After 12 and 16 weeks of treatment, QOL significantly improved in the epoetin beta group compared with placebo (P <.05); this improvement correlated with an increase in Hb concentration (> or = 2 g/dL). A target Hb that could be generally recommended could not be identified.
CONCLUSION: Many severely anemic and transfusion-dependent patients with advanced MM, NHL, and CLL and a low performance status benefited from epoetin therapy, with elimination of severe anemia and transfusion need, and improvement in QOL.
