Dose-intensive chemotherapy with stem cell support as a treatment strategy for bone and soft-tissue sarcomas

Curr Stem Cell Res Ther. 2006 Jan;1(1):29-35. doi: 10.2174/157488806775269098.

Abstract

Whether high-dose chemotherapy with stem cell support improves the long-term outcome for patients with bone and soft-tissue sarcoma is debatable and controversial. Prognosis of patients with unresectable or advanced metastatic sarcoma remains poor with a disease-free survival at 5 years less than 10%; treatment is generally considered to be palliative. Doxorubicin, epirubicin and ifosfamide are the most active single agents with response rates above 20%. Although drug combinations result in higher response rates, superiority against single agent chemotherapy in terms of survival could not have been demonstrated yet. As a dose-response relationship has been shown for the anthracyclines and especially for ifosfamide, high-dose chemotherapy with stem cell support has been evaluated by several investigators. However, all studies were not randomized, comprised small patient numbers and included heterogeneous histological subtypes of soft-tissue sarcomas. Nevertheless, higher doses of chemotherapy result in higher remission rates, which could correlate with longer survival. Well-designed randomized trials should be performed. In this review article, we overview the literature and on the basis of our own data we emphasize the value of high-dose chemotherapy as a treatment option for younger patients with a good performance status in complete or partial remission prior to high-dose chemotherapy.
