  • Title: MDR1 gene expression: evaluation of its use as a molecular marker for prognosis and chemotherapy of bone and soft tissue sarcomas.
    Author: Stein U, Shoemaker RH, Schlag PM.
    Journal: Eur J Cancer; 1996 Jan; 32A(1):86-92. PubMed ID: 8695249.
    Abstract:
    Successful chemotherapeutic treatment of malignant tumours is often limited by the intrinsic or acquired multidrug resistance (MDR). The classical MDR phenotype is characterised by reduced drug accumulation within the cell, caused by overexpression of the MDR1 gene encoded P-glycoprotein. Some reports have been published evaluating MDR1 expression as a molecular marker for response to chemotherapy in human bone and soft tissue sarcomas. In this review, an attempt is made to summarise the accuracy of the measurement of MDR1 expression for use in prognosis, as well as in decisions on chemotherapeutic treatment of sarcomas. In addition, general problems for the performance of such studies is discussed.
