1.Primary Outcome
Title To Collect Matched Tumor Tissue of Trial Participants With Dermatofibrosarcoma Protuberans Before and After Treatment With Imatinib for Future Use in cDNA Microarray and Tissue Array Studies.
Hide Description To obtain matched tumor tissue samples of trial participants dermatofibrosarcoma protuberans (DFSP)for the purpose of determining whether imatinib mesylate affects autocrine/paracrine stimulated signal transduction through the platelet-derived growth factor receptor pathway in DFSP by comparing the level of phosphorylated platelet-derived growth factor receptor beta (PDGFRB) in DFSP after up to 2 weeks of treatment with imatinib to the level of phosphorylated PDGFRB pre-treatment.
Time Frame Prior to and after 2-weeks of imatinib therapy
Hide Outcome Measure Data
Hide Analysis Population Description
Population of paired tissue samples collected from patients with confirmed diagnosis of dermatofibrosarcoma protuberans. Tissue sample will be considered evaluable if there is adequate pre-treatment and on-treatment tumor tissue available for the proposed molecular studies, and resection of DFSP was completed after receiving imatinib.
