Abstract
Well-differentiated/dedifferentiated (WD/DD) liposarcomas, the most common form of liposarcomas, constitute up to 20 % of all soft tissue sarcomas. Several oncogenes are thought to be involved in liposarcoma pathogenesis, mainly MDM2, CDK4 and HMGA2. While MDM2 inhibitors are now tested in clinical trials, a second actionable and promising target appears to be cyclin-dependent kinase 4 (CDK4), which is amplified in up to 90 % of well differentiated or dedifferentiated (WD/DD) liposarcoma. With the paucity of available therapeutic options, the inhibition of CDK4 represent a potential therapeutic option. In this paper, we review the role of CDK4/6 inhibitors in targeting the commonly identified CDK4 amplification in WD/DD liposarcoma, with an emphasis on the published and currently ongoing trials.
