title: [Prognostic factors in myelodysplasia syndromes].
abstract: Large studies have shown that, in MDS, main prognostic factors for survival and progression to AML were the percentage of bone marrow blasts, the number and importance of cytopenias, and the presence of cytogenetic abnormalities. The combination of those 3 factors has yielded an International Prognostic Scoring System (IPSS), with very strong prognostic value for survival and progression to AML, which can therefore be used as a guideline for therapeutic choices. Other important prognostic factors can be derived from molecular studies. They include ras genes mutations, p53 mutations and p15 hypermethylation, but their independent prognostic value remains uncertain.
