Abstract
Whilst autologous stem cell transplantation (auto-SCT) is considered standard of care for relapsed/refractory classical Hodgkin lymphoma, the role of auto-SCT in nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is not well defined due to limited data. We report the first study on auto-SCT for NLPHL with a larger cohort. Eligible for this retrospective registry study were patients reported to the EBMT between 2003 and 2013, aged 18 or older with relapsed/refractory NLPHL who underwent first auto-SCT with disease chemosensitive to salvage therapy. NLPHL transformed to diffuse large B cell lymphoma were excluded. Sixty patients (83% male; median age 40 years) met the eligibility criteria. The median time between diagnosis and transplant was 21 months (IQR 13-58), and the median number of prior treatment lines was 2 (range 1-5), including rituximab in 63% of the patients. At auto-SCT, 62% of the patients were in complete remission (CR) and 38% in partial remission. Seventy-two percent of the patients received BEAM as high-dose therapy. With a median follow-up of 56 months (range 3-105), 5-year progression-free and overall survival (OS) were 66% and 87%, respectively. Univariate comparisons considering age, time from diagnosis to transplant, prior chemotherapy lines, and prior rituximab use failed to identify significant predictors for any survival endpoint except for being in CR at the time of auto-SCT (vs PR, P=.049) for OS. Auto-SCT in patients with relapsed/refractory NLPHL who are sensitive to salvage therapy gives excellent disease control and long-term survival independent of the time interval between diagnosis and transplant.

Abstract
Relapsed/refractory Hodgkin's lymphoma (HL) is treated with salvage chemotherapy and autologous stem cell transplantation (ASCT). Optimal chemotherapy is unknown. We retrospectively analyzed outcomes of 58 patients treated with 2 cycles of high-dose ifosfamide and mitoxantrone (HDIM). HDIM consisted of ifosfamide 5 g/m(2)/day and MESNA 5 g/m(2)/day in continuous 24-h infusion (days 1 and 2), MESNA 2.5 g/m(2) over 12 h (day 3), and mitoxantrone 20 mg/m(2) (day 1) administered every 2 weeks. Stem cells were collected after the first cycle. Responding patients proceeded to ASCT. Toxicity was acceptable. Stem cell mobilization was successful in 96 % of patients. Overall response rate was 74 % (89 % in relapsing and 45 % in refractory patients) with 31 % complete remissions. After a median follow-up of 54 months, 5-year event-free survival was 56 % (69 % for relapsing and 35 % for refractory patients), and 5-year overall survival was 67 % (73 % for relapsing and 55 % for refractory patients). Significant adverse prognostic factors were refractoriness to previous therapy and HDIM failure. No differences in outcomes were noted between patients with early and late relapses or between complete and partial responders. HDIM is a well-tolerated and effective regimen for relapsed and refractory HL with excellent stem cell mobilizing properties. Patients failing HDIM may still benefit from other salvage options.
