RT Journal Article T1 What's in a name? Molecular subclassification of sarcomas creates fresh challenges. A1 Díaz-Martín, Juan A1 Biscuola, Michele A1 Benoit, Jonatan A1 Marcilla, David A1 Civantos, Gema A1 de Álava, Enrique K1 gene fusion K1 sarcoma K1 transcriptomics K1 tumor classification AB This commentary addresses the issue of the classification of sarcomas in the article written by Watson and colleagues published recently in this journal. The article delves into the molecular characterization and distinct phenotypes of some recently described entities (e.g. BCOR-rearranged sarcomas, CIC-fused sarcomas) and describes new groups with common characteristics. This commentary focuses on several questions raised in the article, such as what makes a group of sarcomas become a clinical entity, which should be the main driver of sarcoma classification, how the classification of small round cell sarcomas is expected to evolve and how high-throughput techniques could be applied to sarcoma diagnosis in the short term.
