About this calculator

In general, treatment with erythropoietin (EPO) may improve anemia in about 15-20% of patients with myelodysplastic syndromes (MDS). The combination of EPO and granulocyte colony-stimulating factor (GCSF) may improve response rates to around 40%. This predictive model uses two variables (serum EPO and transfusion need) to identify those who are most likely to respond to these stem-cell factors. The model was developed and validated predominantly in patients with low-risk MDS. Response is defined as a 100% reduction in RBC transfusion need or an increase in hemoglobin level by at least 1.5 g/L.
