Soft tissue sarcomas (STS) are rare mesenchymal tumors with poor prognosis once they present as advanced or metastasized disease. Only few cytostatic drugs have been proven to be active in sarcoma patients and there is a clear need for further treatment options in patients with tumors refractory to standard chemotherapy. Gemcitabine, a nucleoside analogue, has shown activity in several epithelial tumors. Clinical data on the activity of gemcitabine in STS, however, are scarce and heterogeneous. In trials including all subtypes of sarcomas response rates observed with single and multiagent schedules are ranging from 3 to 53%. Histopathological subtypes which seem to exhibit an increased susceptibility to gemcitabine are uterine leiomyosarcomas and angiosarcomas. The synergistic role of other cytostatic drugs, e.g. the role of taxanes, still remains unclear and warrants further trials. We here review the available literature on gemcitabine in the treatment of STS.
