A usually painless malignant tumor that arises from adipose tissue. Microscopically, it may contain a spectrum of neoplastic adipocytes ranging from lipoblasts to pleomorphic malignant adipocytes. Morphologic variants include: well differentiated, dedifferentiated, pleomorphic, and myxoid liposarcoma. The metastatic potential is higher in less differentiated tumors.
Biomarker and diagnostic research for liposarcoma has been reported in the published literature.
No approved treatments are currently available for liposarcoma. An additional 2 compounds hold orphan drug designation.
While no drugs are FDA-approved specifically for liposarcoma, some of the following designated compounds may be used off-label in clinical practice. Treatment decisions should be made in consultation with a specialist familiar with this condition.
The following drugs have received orphan drug designation from the FDA for liposarcoma. Orphan designation reflects regulatory interest and does not indicate approval for treatment.
