Fatores de crescimento hemopoéticos nas síndromes mielodisplásicas Hematopoietic growth factors in myelodysplastic syndromes

By Elvira R. P. Velloso

Abstract

Fatores de crescimento hemopoéticos, como a eritropoetina e a associação da eritropoetina com o fator estimulante de colônias de granulócitos (G-CSF) são utilizados para manejo da anemia, particularmente nas síndromes mielodisplásicas de baixo risco (Anemia refratária e Anemia refratária com sideroblastos em anel e mielodisplasias com sistema de escore de prognóstico internacional de risco baixo ou intermediário I). O nível sérico de eritropoetina e a necessidade transfusional pré-tratamento podem identificar pacientes com melhor chance de resposta a essas terapêuticas de alto custo. O uso indiscriminado de G-CSF em portadores de neutropenia crônica não está indicado, devendo ser individualizado.<br>Treatment with growth factors, particularly erythropoietin (EPO) alone or in association with granulocyte colony-stimulating factor (G-CSF), has been useful in the management of anemia in low-risk patients with myelodysplastic syndromes (refractory anemia, refractory anemia with ringed sideroblasts, low or intermediate-1 IPSS groups). Two pre-treatment variables (serum EPO levels and red blood cell-transfusion needs) can predict erythroid responses to these high cost treatments. The indiscriminate use of G-CSF in neutropenic patients is not recommended although it can be useful in specific situations
