Spots Global Cancer Trial Database for Impact of 2 Transfusion Strategies on Quality of Life of Multitransfused Patients With Low-risk Myelodysplastic Syndrome

Study Description

Brief Summary: Myelodysplastic syndromes (MDS) are heterogeneous malignant bone marrow disorders characterized by ineffective haematopoiesis, peripheral blood cytopenias and variable risk of leukaemia transformation. Anemia is the most common manifestation of bone marrow failure in MDS. After failure with first-line treatment by Erythropoietin, patients survive in average 5 years under long term blood transfusion. Modalities of blood transfusion are not clearly defined. Then, the objective of this randomized comparative multicentric study is to compare two modalities of threshold for transfusion: * Restrictive group: Hb \< 80g/L and Hb maintain between 80 and 100g/L * Liberal group: Hb \< 100g/L and Hb maintain between 100 and 120g/L

Detailed Description: Myelodysplastic syndromes (MDS) are heterogeneous malignant bone marrow disorders characterized by ineffective haematopoiesis, peripheral blood cytopenias and variable risk of leukaemia transformation. The median age at diagnosis is 75 years. The incidence is about 30 per 100,000, over 70 years. Etiology is unknown in more than 85% of cases, chemo-induced causes and family cases are well individualized. Diagnosis, prognosis, and classification (WHO) are based on joint cytologic analysis of peripheral blood, bone marrow, and spinal cytogenetic analysis. The main therapeutic objectives in low-risk MDS are to correct cytopenias, improve quality of life and prevent aggravation of co-morbidities. Anemia is the most common manifestation of bone marrow failure in MDS. It is encountered in 80% of cases at diagnosis and almost always occurs in the progression of the disease. Its presence and importance have a pejorative prognostic value, but it is not clear whether this anemia is indicative of a more serious clonal disease or whether it is the repercussions of anemia that lead to a more severe prognosis. After failure with first-line treatment by Erythropoietin (EPO), patients survive in average 5 years under long term blood transfusion. Modalities of blood transfusion are not clearly defined. Studies in the general geriatric population and in cases of acute anemia are in favor of a restrictive transfusion regimen (threshold around 70 g/L), while experience during MDS with EPO suggest that maintaining a higher hemoglobin count could have a favorable impact on quality of life, physical performance, or even survival of patients with MDS. Then, the objective of this randomized comparative multicentric study is to compare two modalities of threshold for transfusion: * Restrictive group: Hb \< 80g/L and Hb maintain between 80 and 100g/L * Liberal group: Hb \< 100g/L and Hb maintain between 100 and 120g/L
