Summary:The purpose of the study was to evaluate in patients with recurrent intermediate-grade NHL, the tolerance to and efficacy of an intensive salvage regimen consisting of high doses of ifosfamide, etoposide and mitoxantrone with G-CSF support, followed by autologous stem cell transplantation and to identify prognostic fac- the 44 patients proceeded to autologous stem cell transplantation and one transplant-related death occurred. With a median follow-up of 52 months, progression-free survival at 2 years is 38% ± 14% and survival is 52% ± 15%. Data from these 44 patients were pooled with data on 53 patients who had received salvage treatment with MINE-ESHAP, for a multivariate analysis of prognostic factors. In multivariate analysis, serum LDH was strongly associated with survival. The use of a more intensive salvage regimen, did not result in a significant increase in long-term outcome, despite a high response rate. In conclusion, duration of treatment, response rates, treatment-related mortality and survival compare favorably with previous salvage regimens, but recurrence remains a major problem. Long-term survival in recurrent large cell lymphoma is influenced more by disease characteristics than by the type of salvage regimen used. Bone Marrow Transplantation (2001) 27, 397-404. Keywords: lymphoma; transplantation; prognostic factors Commonly used regimens for reinduction of patients with recurrent aggressive non-Hodgkin's lymphoma (NHL) are either platinum-based (DHAP or ESAP), 1 or ifosfamidebased (most commonly MINE). 2 Both types of regimens induce responses in approximately two thirds of patients and complete remission rates of approximately 30% to 40%. 3 Autologous transplantation results in durable remissions in approximately half of the responding patients, 3 but lack of response to pre-transplant chemotherapy and recurrence after transplantation limit the clinical impact of this strategy. Overall only approximately 20% of patients with recurrent NHL targeted for auto-transplant, achieve durable remissions. 4 Dose-intensity can be optimized by increasing the dose of a particular drug, or by decreasing the treatment interval (ie increasing the dose density). 5 We studied a salvage regimen consisting of high doses of ifosfamide, etoposide alternating with high-dose ifosfamide and mitoxantrone. With G-CSF support and prophylactic antibiotics, we were able
