I. To determine whether systemic administration of interferon (IFN) gamma (recombinant interferon gamma) will increase class I major histocompatibility complex (MHC) expression in synovial sarcoma (SS) and myxoid/round cell liposarcoma (MRCL) tumors.
I. To determine whether systemic administration of IFN gamma will increase class II MHC expression in SS and MRCL tumors.
II. To examine changes in the immune response to MRCL and SS by examining changes in the immune infiltrates, antibody response and antigen specific T cell response before and after IFN gamma treatment.
Patients receive recombinant interferon gamma subcutaneously (SC) every 7 days for 4 weeks before surgery or thrice weekly for 2 weeks before surgery.
After completion of study, patients are followed up at 2 weeks post-surgery.

|Primary Purpose:||Basic Science|
|Official Title:||A Pilot Study to Test Whether Systemic Interferon Gamma Increases Tumor Class I MHC Expression in Patients With Synovial Sarcoma and Myxoid/Round Cell Liposarcoma|
|Actual Study Start Date :||September 25, 2013|
|Estimated Primary Completion Date :||October 1, 2018|
Experimental: Basic science (interferon gamma and MHC expression)
Patients receive recombinant interferon gamma SC every 7 days for 4 weeks before surgery or thrice weekly for 2 weeks before surgery.
Other: Laboratory Biomarker Analysis
Biological: Recombinant Interferon Gamma
- Change in class I major histocompatibility complex (MHC) expression after treatment with IFN gamma as determined by immunohistochemistry (IHC) [ Time Frame: Baseline to up to 2 weeks post-surgery ]It would be highly relevant to observe marked increase macrophages (effect size > 2.5). Four patients gives over 90% power to detect such a large increase with a two-tailed alpha of 0.05.
