Primary Outcome Measures:
  • Identification of molecular targets that would improve the diagnosis, prognosis, and/or treatment of STS [ Time Frame: 3 months ] [ Designated as safety issue: No ]

Enrollment: 27
Study Start Date: August 2005
Study Completion Date: June 2013
Primary Completion Date: June 2013 (Final data collection date for primary outcome measure)
Detailed Description:

OBJECTIVES:

  • To develop a pilot program for the collection, archiving, and experimental analyses of soft tissue sarcomas (STS).
  • To obtain STS tumors from cancer patients undergoing tumor removal or core needle biopsies.
  • To evaluate cellular and molecular factors involved in STS oncogenesis by studying samples derived from human tumor specimens.
  • To develop an accompanying bioinformatics database of the demographics of STS patients from which tumor specimens are derived for experimental study.

OUTLINE: Tumor tissue samples are analyzed for gene and protein expression by cDNA microarray analysis, RT-PCR, immunohistochemistry, in vitro transformation assays, RNA interference, and Western blot or immunoprecipitation.
