For patients with anemia, consider erythropoietin or epoetin alfa (Procrit) at 40,000-60,000 U, administered subcutaneously once weekly, or darbepoetin alfa 300 mcg, with weekly subcutaneous administration.

Growth factors stimulate blood cell production. Endogenous erythropoietin stimulates red blood cell hematopoiesis. Recombinant human erythropoietin (epoetin alfa) stimulates erythropoiesis in anemic conditions. Colony-stimulating factors act on hematopoietic cells to stimulate hematopoietic progenitor cell proliferation and differentiation. Interleukins stimulate stem cell proliferation.

Administer growth factor support (ie, granulocyte colony-stimulating factor [G-CSF], granulocyte-macrophage colony-stimulating factor [GM-CSF]) to patients with a previous episode of febrile neutropenia, during subsequent cycles. Patients who administer growth factors to themselves should be carefully advised on sterile techniques, and patients with fevers during periods of neutropenia should immediately seek the attention of the treating physician.
