Pleomorphic liposarcoma is a rare malignancy that represents approximately 5–10% of all liposarcomas [1,2,3,4].

What is the survival rate of pleomorphic liposarcoma?

Ten-year survival rates are 87% in well-differentiated liposarcoma, 76% in myxoid liposarcoma and 39% in pleomorphic liposarcoma. However, the site of disease has a strong effect on prognosis of well-differentiated and de-differentiated liposarcoma.

How quickly does liposarcoma spread?

Well-differentiated liposarcoma is the most common form. It grows slowly and generally does not spread to other parts of the body. Well-differentiated liposarcoma has a tendency to regrow after initial treatment.

Well-differentiated liposarcoma has a 100% 5-year survival rate, and most myxoid types have 88% 5-year survival rates. Round-cell and dedifferentiated liposarcomas have a 5-year survival rate of about 50%. Liposarcoma is a rare type of cancer that develops in connective tissues that resemble fat cells.

How many types of liposarcoma are there?

There are five subtypes of liposarcoma: well differentiated, dedifferentiated, myxoid, round cell and pleomorphic. The well differentiated type is less aggressive and tends to be a large painless mass found in deeper tissues and in the retroperitoneum.
