Revisiting Use of Growth Factors in Myelodysplastic Syndromes
Newman, Kam,Maness-Harris, Lori,El-Hemaidi, Ihab,Akhtari, Mojtaba Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.4
Myelodysplastic syndromes (MDS) represent a heterogeneous group of clonal hematologic neoplasms characterized by morphologic dysplasia, aberrant hematopoiesis and peripheral blood refractory cytopenias. MDS is recognized to be associated with an increased risk of symptomatic anemia, infectious complications and bleeding diathesis, as well as a risk of progression to acute myeloid leukemia, particularly in patients with a high IPSS score. The advent of use of hematopoietic growth factors such as granulocyte colony-stimulating factor (G-CSF) and recombinant erythropoietin (EPO) has improved symptoms in MDS patients in addition to some data that suggest there might be an improvement in survival. G-CSF is an effective therapeutic option in MDS patients, and it should be considered for the management of refractory symptomatic cytopenias. G-CSF and EPO in combination can improve outcomes in appropriate MDS patients such as those with lower-risk MDS and refractory anemia with ring sideroblasts (RARS). This article reviews use of growth factors for lower-risk MDS patients, and examines the data for G-CSF, EPO and thrombopietic growth factors (TPO) that are available or being developed as therapeutic modalities for this challenging disease.
A Primary Care Approach to Myelodysplastic Syndromes

Myelodysplastic syndromes (MDS) are probably the most common hematologic malignancies in adults over the age of 60 and are a major source of morbidity and mortality among older age groups. Diagnosis and management of this chronic blood cancer has evolved significantly in recent years and there are Food and Drug Administration-approved therapies that can extend patients’ life expectancy and improve quality of life. Primary care physicians (PCPs) are often involved in the process of diagnosis and follow-up of MDS patients, especially those in low-risk groups. They can therefore play an important role in improving patient care and quality of life by ensuring early referral and participating in supportive management. There is also a shortage of oncologists which increases the importance of the role of PCPs in management of MDS patients. In the face of limited resources, PCPs can improve access and quality of care in MDS patients. This article provides an overview of the common manifestations, diagnostic approaches, and therapeutic modalities of MDS for PCPs, with a focus on when to suspect MDS, when a referral is appropriate, and how to provide appropriate supportive care for patients diagnosed with MDS.
