Study Description
Brief Summary:
This pilot clinical trial studies the effect of recombinant interferon gamma on tissue in treating patients with soft tissue sarcoma. Interferon gamma may interfere with the growth of tumor cells.

Condition or disease Intervention/treatment
Myxoid Liposarcoma Round Cell Liposarcoma Synovial Sarcoma Other: Laboratory Biomarker Analysis Biological: Recombinant Interferon Gamma

Detailed Description:


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.

Study Design

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 12 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
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

Arms and Interventions

Arm Intervention/treatment
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

Outcome Measures

Primary Outcome Measures :
  1. Change in class I MHC expression after treatment with IFN gamma as determined by immunohistochemistry (IHC) [ Time Frame: Baseline to up to 2 weeks post-surgery ]
    It is estimated that the true mean change in expression following IFN gamma will be 50% (for homogenous expression) with a standard deviation of 30%. Seven patients will provide 95% power to observe a change in expression (before IFN vs. after IFN) that is statistically significantly (at the 2-sided significance level of .05) different from a change of zero.

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • A superficial tumor easily and safely accessible for a research biopsy or are being considered for resection or biopsy of their tumor as part of standard of care and have recent pathology
  • Zubrod performance status of '0-2' or Karnofsky score > 60%
  • No treatment with systemic anti-cancer treatment (chemotherapy or biologics) within 2 weeks of starting interferon gamma
  • Patients with a history of coronary artery disease must have had a normal stress test within 180 days of starting IFN gamma
  • Must have been off metformin for at least 2 weeks prior to starting IFN gamma
  • No use of full dose, therapeutic anti-coagulation; however, low dose warfarin for catheter prophylaxis or acetylsalicylic acid are acceptable
