Study Description

Well-differentiated (WD) and de-differentiated (DD) liposarcoma, subtypes of adipocytic sarcomas, are pathologically and clinically dissimilar, but are poorly distinguishable at the molecular level. These tumors harbor neochromosomes formed from amplifications and rearrangements of chr12q. Nineteen selected patients with matched WD and DD tumors underwent extensive exomic and transcriptomic profiling to distinguish genomic features between the two subtypes. Shared point mutations suggest a common tumor origin and de-differentiated tumors have higher burdens of deletions.
