“…Drug-induced myelosuppression not only limits the treatments with cytostatic agents, but also is a risk factor for poor prognosis, as it substantially diminishes immunity and other systems against malignancy (Richardson and Johnson, 1997, Busch et al, 1990, Nurgalieva et al, 2010). Bone marrow transplantation and the supplements of erythropoietin (Epoetin), granulocyte colony-stimulating factor (G-CSF, Neupogen) and interleukin-11 (Oprelvekin) have been demonstrated recovering bone marrow and significantly improvement chemotherapy outcome (Bartsch and Steger, 2009, Seidman, 2006, Moore and Crom, 2006, Janni et al, 2001, Timmer-Bonte et al, 2005, Hood, 2003, Carey, 2003). An understanding of cellular mechanisms underlying drug-induced myelosuppression may guide development of chemotherapeutics with high efficacy and little bone marrow toxicity.…”
