Spots Global Cancer Trial Database for Myelodysplasic Syndromes and Risk Factors for Infection

Study Description

Brief Summary: Myelodysplastic Syndromes (MDS) are characterized by quantitative and qualitative bone marrow failure and by a disorder of the medullary production which is a pre-leukemic state which can evolve into acute myeloid leukemia. The risk of leukemic transformation is estimated by the score IPSS (International Prognostic Score System). We distinguish the MDS of low risk (IPSS\<1) and those of high risk of leukemic transformation (IPSS=1,5). Besides the risk of leukemic transformation, MDS much be complicated of infections which could be life-threatening. The risk of developing first infection after the diagnosis of MDS of high risk is probably influenced by anamnestic (disease duration, comorbidities), clinical (veinous central catheter, previous hospitalization), biological (neutropenia, lymphopenia, serum ferritin) and therapeutics (demethylating agent, lenalidomide, erythropoietin, G-CSF, transfusions, anti-infectious preventive treatment) factors. Their identification will allow for improved targeting of the population which is is likely to benefit from anti-infective prophylaxis Primary objective is to identify risk factors associated with first acute episode of infection in patients with MDS, by comparing index cases and matched control cases who did not develop infection episode since diagnosis. Secondary objectives are to explore nature and severity of infectious episodes, number of recurrences during 1 year of follow up and survival at 6 and 12 months
