SARC004 May 6, 2021 Neoadjuvant Imatinib in Dermatofibrosarcoma Protuberans TYPE OF SARCOMA: Dermatofirbrosarcoma ProtuberansDRUG: Gleevec (Imatinib Mesylate) ACCRUAL STATUS: Completed OVERALL STUDY PRINCIPAL INVESTIGATOR:Scott Schuetze, MD, PhDUniversity of Michigan CLINICALTRIALS.GOV IDENTIFIER: NCT00243191 FOR STUDY DETAILS AND ELIGIBILITY CRITERIA: CLINICALTRIALS.GOV IMPACT STATEMENT:SARC004 sought to collect dermatofibrosarcoma protuberans samples before and during treatment with imatinib to investigate early changes in activity of platelet-derived growth factor receptors and other key signaling molecules. The trial determined that tumor biopsy for sample collection before and during treatment was safe for patients. Paired tumor samples have been collected for advanced proteomic analysis.
