round cell liposarcoma

A high-grade radiosensitive sarcoma which most commonly involves the limbs (2/3 thigh) and deep soft tissue. Round cell liposarcoma is at the aggressive end of a spectrum of liposarcomas, at the “benign” end of which is myxoid liposarcoma.

DiffDx
Mxofibrosarcoma, metastatic carcinoma, melanoma, B- or T-cell lymphoma, Ewing sarcoma/PNET.

Prognosis
Poor outcome if ≥ 5% of tumour is composed of round cells—it metastasises to the spine, retroperitoneum, pleural cavity, soft tissue, pelvis, lung. Median survival is < 5 years.

According to the expanded deal, the firms will accelerate the development of NY-ESO therapy into pivotal synovial sarcoma studies and also explore development in myxoid round cell liposarcoma. The companies are also likely to start around eight proof-of-principle studies evaluating combinations with other therapies, including checkpoint inhibitors.

Most of myxoid/round cell liposarcomas of are found primarily in the limb and their severity may vary from low grade to high-grade tumor as seen in pure myxoid and pure round cell liposarcoma respectively; but in some cases transitional features may also be seen which behavior may depend upon the presence of round cell quantity.

Myxoid-round cell liposarcoma is a common subtype of liposarcoma characterized by the t(12;16)(q13;p11) reciprocal translocation, which results in the formation of the FUS-DDIT3 chimeric gene (128,129) found in about 95% of myxoid and round cell liposarcoma cases (Table 3).
