| pubmed-article:9671332 | pubmed:abstractText | High-dose chemotherapy (HDCT) with bone marrow transplantation (BMT) is associated with the development of significant anemia. The anemia is caused mainly by myelosuppression, although gastrointestinal-, genitourinary-, and phlebotomy-induced blood loss may also contribute. The number of red blood cell units transfused during the first 30 days following HDCT depends on the chemotherapy used, the underlying disease, and whether BMT was allogeneic, autologous, and used either peripheral blood stem cell or bone marrow support. Epoetin alfa has been used to treat the anemia that develops in the HDCT setting. Controlled studies in patients with both hematologic malignancies and solid tumors who were given epoetin alfa following HDCT have shown that red blood cell transfusion requirements decrease in patients receiving allogeneic BMT. Results using epoetin alfa in patients receiving autologous BMT have been disappointing. Alternatively, combination therapy with granulocyte colony-stimulating factor and epoetin alfa has been effective in mobilizing stem cell and committed myeloid/erythroid precursors before HDCT, but has not resulted in a lower red blood cell transfusion requirement after HDCT. Administration of epoetin alfa before HDCT while the bone marrow is still responsive to growth factors may be a new strategy with which to decrease the anemia in this setting. | lld:pubmed |
