Anemia is the most relevant clinical problem for the majority of patients with MDS. More than 90% of MDS patients are anemic at the time of diagnosis, and severe anemia is observed in about 60% of cases. Once anemia is symptomatic, red blood cell (RBC) transfusions are the mainstays of therapy. We found that the onset of a regular transfusion requirement in MDS patients is associated with a worsening of prognosis in multivariable analysis, and hence, transfusion-dependency can be viewed as an independent indicator of the severity of the disease and an independent prognostic factor. The prognostic value of transfusion-dependency was found to be associated with transfusion burden and intensity of transfusion requirement.

Abstract
Anemia is the most relevant clinical problem for the majority of patients with MDS. More than 90% of MDS patients are anemic at the time of diagnosis, and severe anemia is observed in about 60% of cases. Once anemia is symptomatic, red blood cell (RBC) transfusions are the mainstays of therapy. We found that the onset of a regular transfusion requirement in MDS patients is associated with a worsening of prognosis in multivariable analysis, and hence, transfusion-dependency can be viewed as an independent indicator of the severity of the disease and an independent prognostic factor. The prognostic value of transfusion-dependency was found to be associated with transfusion burden and intensity of transfusion requirement.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
