What is liposarcoma?

Liposarcoma is a tumor that arises from fat tissue.  This tumor often occurs in the thigh, behind the knee, or in the abdomen, but it can be found in other parts of the body.  Because a liposarcoma may grow into surrounding tissues or organs, it is considered a malignant tumor.[1]

How might liposarcoma be treated?

The treatment for liposarcoma depends on the type, size, and location of the tumor.  Surgery to remove the tumor is often the first treatment.  When the tumor is in the abdomen, it may be difficult to remove completely, especially if the tumor is growing near important organs that cannot be removed.  If the entire tumor cannot be removed during surgery, radiation therapy may be used after surgery to kill any cancer cells that remain to reduce the chance of the tumor coming back (a recurrence).   Chemotherapy is another treatment that can kill remaining cancer cells following surgery, though it is not usually used to treat low-grade sarcomas. [2] [3]

Sometimes radiation therapy or chemotherapy may be done prior to surgery to shrink the tumor; this may increase the chance of removing the whole tumor during surgery while limiting the impact to other organs. [2] [3]
