Prospective study of high-dose chemotherapy and autologous peripheral stem cell transplantation in adult patients with advanced desmoplastic small round-cell tumour.

A total of 10 desmoplastic small round-cell tumour patients were treated by high-dose chemotherapy with stem cell support. After high-dose chemotherapy, no complete response conversion was obtained and EWS-WT1 fusion transcript detection was positive in the peripheral blood during follow-up in all patients. High-dose chemotherapy did not seem to change the results in desmoplastic small round-cell tumour.
