Expression Profiling in Soft Tissue Sarcomas With Emphasis on Synovial Sarcoma, Gastrointestinal Stromal Tumor, and LeiomyosarcomaWest, Robert B. MD, PhDAdvances in Anatomic Pathology: September 2010 - Volume 17 - Issue 5 - p 366–373 doi: 10.1097/PAP.0b013e3181ec7428 Review Articles Abstract Author Information Sarcomas are defined as malignant neoplasms derived from mesenchymal tissues. A variety of different molecular approaches, including gene expression profiling, have identified candidate biomarkers and insights into sarcoma biology that will aid in the diagnosis and treatment of these tumors. Many gene expression profiling findings have been translated into immunohistochemical tests for diagnostic, prognostic, or predictive purposes. This review details gene expression studies done in 3 sarcomas, synovial sarcoma, gastrointestinal stromal tumor, and leiomyosarcoma.
