Recent Clinical and Molecular Advances for the Classification of Myelodysplastic Neoplasms.

ABSTRACT

Several major updates have recently occurred for the NCCN Guidelines for Myelodysplastic Syndromes (MDS) based on a number of prominent articles that have particular clinical and biologic impact for the field. These changes, which have been included in the current iteration of the NCCN Guidelines (Version 1.2023), include the WHO 2022 classification of MDS as well as the ICC suggestions for same. In addition, the molecular underpinning of MDS has been greatly updated with the generation of the Molecular International Prognostic Scoring System (IPSS-M) and an improved understanding to the prognostic implications of mutated TP53 subtypes, which are additive to the revised IPSS (IPSS-R) for stratification and management of patients with MDS. This report emphasizes the major components of the relevant changes to serve as a guide for therapeutic decision-making for patients with MDS.
