Background: The outcome for patients with recurrent or progressive Ewing's sarcoma family of tumours (ESFT) is poor. High dose therapy (HDT) has been used for a number of years in an attempt to improve survival; however, evidence for the efficacy of this treatment remains limited.
Patients and methods: Between 1992 and 2004, 33 patients with recurrent or progressive ESFT were treated with HDT with bone marrow (n = 2), peripheral blood stem cell (n = 30), or bone marrow and peripheral blood stem cell support (n = 1), at a single institution. HDT was with busulphan and melphalan in 22 patients; melphalan and etoposide in seven patients, three with total body irradiation (TBI); melphalan in three patients (2 with TBI), and busulphan and cyclophosphamide in one patient.
Results: The 2 and 5 year event free survival was 42.5% (95% CI, 2659%) and 38.2% (95% CI, 2155%) respectively. There was one treatment related death from colitis, and grade 4 infection was observed in two patients.
Conclusions: Long-term survival can be attained in patients with recurrent or refractory ESFT treated with HDT. However, this treatment is associated with severe toxicity. A need remains for prospective randomised clinical trials of HDT in this group of patients.
