Intensive chemotherapy requiring rescue with autologous bone marrow may be an encouraging mode of treatment for poor prognosis Ewing's sarcoma (ES). In vitro chemosensitivity test may be useful for establishing an effective purging condition. We studied the in vitro effects of a variety of chemotherapeutic agents on two established ES cell lines (ES-5838 and ES-A4573) and marrow colony-forming unit-granulocyte macrophage (CFU-GM). 4-Hydroperoxycyclophosphamide (4-HC), at 100 microM produced complete inhibition (greater than 5 log) of clonogenic growth of both ES cell lines and spared 6.9% of normal CFU-GM growth. Etoposide (VP-16), at 100 microM produced 3-3.5 log inhibition of ES cell lines and complete inhibition of CFU-GM growth. Adriamycin (ADR) and vincristine (VCR) were more cytotoxic to ES-5838 cells than ES-A4573 cells. ADR at 1 microM produced 99.7% inhibition of ES-5838 cells, 92.2% of ES-A4573 cells, and 86% inhibition of CFU-GM. VCR at 1 microM produced 98.6% inhibition of ES-5838 cells, only 43.7% of ES-A4573 cells, and 75% inhibition of CFU-GM growth. Addition of verapamil did not enhance VCR cytotoxicity of ES cell lines. These studies indicate that 4-HC may be a useful agent for purging metastatic ES cells from the bone marrow for autologous marrow transplantation.
