Studying Tumor Tissue Samples From Patients With Soft Tissue Sarcoma

March 20, 2014 updated by: University of Arizona

LABORATORY STUDIES OF SOFT TISSUE SARCOMAS

RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer.

PURPOSE: This research study is looking at tumor tissue samples from patients with soft tissue sarcoma.

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.
