In this article, we review the current literature about azacitidine for the treatment of MDS, AML and in the stem cell transplant field.Expert opinion: Azacitidine is an old/new drug that gained more attention after its FDA approval for MDS. It is the only drug that showed survival benefit in MDS, in a Phase III randomized controlled trial. Azacitidine also has an important role in treat...
