Summary:

      This phase II trial studies how well efatutazone dihydrochloride works in treating patients
      with previously treated myxoid liposarcoma that cannot be removed by surgery. Drugs used in
      chemotherapy, such as efatutazone dihydrochloride, work in different ways to stop the growth
      of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping
      them from spreading.
    

Eligibility criteria:

        -  Patients must have a formalin-fixed, paraffin-embedded (FFPE) tumor block OR 1

               -  Pericardial involvement with tumor

               -  Grade 2 or higher pleural effusion =< 6 months

          -  No symptomatic, untreated, or uncontrolled brain metastases present

          -  Not pregnant and not nursing; for women of childbearing potential only, a negative
             pregnancy test done =< 7 days prior to registration is required; a female of

                  has had menses at any time in the preceding 12 consecutive months)

          -  Patients with diabetes mellitus requiring concurrent treatment with insulin or
             thiazolidinedione (TZD) oral agents are not eligible

          -  Absolute neutrophil count (ANC) >= 1,000/mm^3

          -  Platelet count >= 75,000/mm^3
