Tissue Sample Collection From Patients With Soft Tissue Sarcoma of the Arms, Hands, Legs, or Feet Treated on Clinial Trial CRUK-VORTEX
RATIONALE: Collecting and storing samples of tumor tissue from patients with soft tissue sarcoma to test in the laboratory may help the study of cancer in the future.
PURPOSE: This laboratory is collecting tissue samples from patients with soft tissue sarcoma of the arms, hands, legs, or feet treated on clinical trial CRUK-VORTEX.
- Determine early in the course of treatment which patients treated on clinical trial CRUK-VORTEX have an increased likelihood of distant metastases so as to highlight individuals who might benefit from early adjuvant systemic therapy.
OUTLINE: This is a multicenter study.
Tumour and normal tissue samples will be taken at the time of surgery during treatment on clinical trial CRUK-VORTEXand preserved for future microarray analyses. Tissue microarrays will be produced from both tumor and normal tissues. Blood samples will be collected for future DNA analysis.

Medical and Biotech [MESH] Definitions
A mass spectrometric technique that is used for the analysis of large biomolecules. Analyte molecules are embedded in an excess matrix of small organic molecules that show a high resonant absorption at the laser wavelength used. The matrix absorbs the laser energy, thus inducing a soft disintegration of the sample-matrix mixture into free (gas phase) matrix and analyte molecules and molecular ions. In general, only molecular ions of the analyte molecules are produced, and almost no fragmentation occurs. This makes the method well suited for molecular weight determinations and mixture analysis.
The simultaneous analysis, on a microchip, of multiple samples or targets arranged in an array format.
The analysis of a chemical substance by inserting a sample into a carrier stream of reagent using a sample injection valve that propels the sample downstream where mixing occurs in a coiled tube, then passes into a flow-through detector and a recorder or other data handling device.
MOLECULAR BIOLOGY techniques used in the diagnosis of disease. Included are such techniques as IN SITU HYBRIDIZATION of chromosomes for CYTOGENETIC ANALYSIS; OLIGONUCLEOTIDE ARRAY SEQUENCE ANALYSIS of gene expression patterns in disease states; identification of pathogenic organisms by analysis of species specific DNA sequences; and detection of mutations with POLYMERASE CHAIN REACTION.
Body of knowledge related to the use of organisms, cells or cell-derived constituents for the purpose of developing products which are technically, scientifically and clinically useful. Alteration of biologic function at the molecular level (i.e., GENETIC ENGINEERING) is a central focus; laboratory methods used include TRANSFECTION and CLONING technologies, sequence and structure analysis algorithms, computer databases, and gene and protein structure function analysis and prediction.
