Abstract
The treatment of metastatic soft tissue sarcomas in adults is one of the most challenging areas in oncology. While multidisciplinary management of early-stage, localized disease has led to a number of improved outcomes, therapy of unresectable or advanced disease remains problematic. Virtually every conventional cytotoxic agent has been systematically assessed in this malignancy, yet only a handful have demonstrated significant activity. Adriamycin and ifosfamide are the only chemotherapeutic drugs to have consistently produced response rates of over 20% when given as single agents and these two drugs have been exhaustively studied alone or in combination. Recent efforts to improve response rates and, by inference, disease-free survival and overall survival, have involved exploration of high-dose regimen incorporating growth factors and/or autologous cellular support. In this article, the status of dose-intensive chemotherapy in advanced adult soft tissue sarcomas (excluding pediatric histologies, such as Ewing's sarcoma and rhabdomyosarcoma) will be discussed. Emphasis will be placed on data from randomized Phase III trials but information from Phase I/II studies will also be reviewed and recommendations will be made on a systematic analysis of the data.
