Назначение эритропоэтина у больных с миеломой в развернутой стадии, похоже, ассоциируется с лучшей выживаемостью:

Background: Recombinant human erythropoietin (rhEPO) is effective for the treatment of anemia associated with multiple myeloma. Data from animal studies and case reports suggest that rhEPO has antineoplastic properties.
Methods: Two hundred and ninety-two patients enrolled on different chemotherapy clinical trials at the Cleveland Clinic Myeloma Program between 1997 and 2003 were the subjects of this study. Information on erythropoietin use as well as baseline prognostic variables were collected retrospectively.
Results: The population consisted of 257 patients with multiple myeloma treated at the Cleveland Clinic Foundation from 1997 to 2003 and followed for at least 1 month. Thirty-five patients were excluded from this analysis because information on erythropoietin use was not available. One hundred and twenty-seven patients received rhEPO for at least 1 month and the rest did not received rhEPO. On average, patients who received rhEPO were older, had a higher Southwest Oncology Group (SWOG) stage, higher serum creatinine, lower serum hemoglobin, higher beta(2)-microglobulin, lower platelet counts, and a longer time from diagnosis to enrollment at the myeloma program (p < 0.001 for all). After adjusting for age, months from diagnosis to enrollment, serum creatinine, hemoglobin, platelet count, and beta(2)-microglobulin, the use of rhEPO was associated with improved overall survival (hazard ratio = 0.6; 95% CI = 0.38-0.94) in patients with SWOG stages II, III and IV but not in patients with SWOG stage I.
Conclusion: rhEPO was associated with improved overall survival in this population of anemic multiple myeloma patients with SWOG stages of II, III and IV.
