Abstract Introduction The role of both autologous (autoSCT) and allogeneic stem cell transplantation (alloSCT) in the management of patients with mantle cell lymphoma (MCL) remains to be clarified. In the absence of prospective comparative trials decision making for clinicians remains challenging. We have conducted a consensus project to provide guidance on how stem cell transplantation should be employed in MCL. Methods This was a collaborative project between the Lymphoma Working Party of the EBMT and the European Mantle Cell Lymphoma Network. The RAND modified Delphi consensus procedure was used. 12 clinicians, recognized for their expertise in MCL, from both transplant and non-transplant centres contributed. A literature search was performed and consensus statements were formulated. Panel members ranked each statement. The statements were reviewed and modified and then a second round of ranking was performed. Results Consensus agreement was reached on the following statements: 1. Patients should be considered for transplant strategies based on their biological age and comorbidities and not just chronological age. 2. An autoSCT should be considered as the standard first line consolidation therapy in all patients considered suitable for high dose therapy. 3. First line induction therapy prior to SCT should incorporate high dose cytarabine and Rituximab based regimens. 4. Patients achieving either complete remission or partial remission following induction therapy should be considered for autoSCT. 5. Patients failing to achieve a PR or CR following induction therapy should not proceed directly to an autoSCT. 6. Patients undergoing an allogeneic SCT should receive reduced intensity conditioning regimens. There was consensus disagreeing with the following statement: Prognostic criteria are available that permit the identification of low risk patients in need of first line therapy who should be considered for non-transplant based treatment. There was partial consensus agreeing with the following statements: 1. Patients relapsing after an autoSCT should be considered for an allogeneic stem cell transplant following reinduction therapy.2. Patients with evidence of MRD relapse post alloSCT should, in the absence of graft versus host disease, be considered for rapid withdrawal of immunesuppression and donor lymphocyte infusions. There was a partial consensus disagreeing with the following statements: 1 Patients should receive Rituximab maintenance following first line autologous stem cell transplant. 2. There are sufficient prognostic criteria to identify patients who should undergo an allogeneic stem cell transplantation as first line consolidation. 3. In patients relapsing after non-transplant first line therapy there are sufficient prognostic criteria to determine whether autoSCT or alloSCT consolidation should be used. Finally there was no consensus with respect to the following statements. 1. Disease response to induction therapy prior to autoSCT should be assessed by PET scan. 2. Minimal residual disease (MRD) negativity is mandatory prior to autoSCT. 3. A TBI based regimen should be considered as the standard for conditioning prior to autoSCT. 4. Patients undergoing an autoSCT should receive in-vivo purging with Rituximab at the time of high dose conditioning therapy. 5. Patients with relapsed disease following non-transplant first line therapy should be considered for an autologous stem cell transplant to consolidate second (or higher) response. 6. Patients with relapsed disease following non-transplant first line therapy should be considered for an allogeneic SCT to consolidate second (or higher) response. 7. Patients undergoing autoSCT should be monitored for MRD post transplant. 8. Patients with evidence of MRD relapse post autoSCT should receive preemptive Rituximab. 9. Patients undergoing alloSCT should be monitored for MRD post transplant. Conclusions Consensus was obtained with regard to the role of autologous SCT in first line consolidation. However, the application of appropriate clinical and molecular prognostic factors to guide therapeutic decisions and the role of allogeneic transplantation warrant further clinical investigation.

Abstract Background Mantle cell lymphoma is a disease of the elderly, with a median age of 70 years. Younger patients may be treated with potentially curative treatment including high dose chemotherapy. For elderly patients, however, no standard therapy has been defined. In the current trial, we investigate if the addition of lenalidomide (LEN) to rituximab (R)+bendamustine (B) (B 90 mg/m2 D1-2 and R 375 mg/m2 D1) followed by maintenance with LEN for 7 months may enhance efficacy, with manageable toxicity, for the older population of MCL patients. Methods Eligibility criteria were age > 65 years, or ≤ 65 years, unable to tolerate high dose chemotherapy, with untreated mantle cell lymphoma, stage II-IV. BR was given for 6 cycles q4w. In the phase I part, the MTD of LEN was established as 10 mg days 1-14 during the induction phase, cycles 2-6. Prednisolone 20 mg days 1-14 was given during cycle 2. When LEN was initially given from cycle 1, we encountered unexpected grade III-IV toxicity in the form of cutaneous and allergic reactions. In the maintenance phase, LEN single therapy was given as follows: cycles 7-8 - 10 mg days 1-21, cycles 9-13 - 15 mg days 1-21. Results The trial was concluded June 1, 2013, after inclusion of 51 patients, of whom 24 were in the phase I part. The median age is 72 years. According to MIPI, 55% were high risk. Presently, 29 patients are evaluable for response after 6 cycles LBR. ORR is 28/29 (97%), CR+CRu 23 (79%). 17 out of 28 evaluable patients (61%) were MRD-negative after 6 cycles. After a median follow-up of 18 months, the median PFS has not been reached, and the estimated PFS at 2 years is 74%. Eight patients have died, 3 due disease progression, 3 due to treatment related toxicity, 1 of lung cancer in a heavy smoker, 1 of CMML. Overall survival at 2 years is 87%. Conclusions When omitted in cycle 1, lenalidomide in combination with R-bendamustine is feasible as first-line therapy in older patients with MCL, and is associated with a high response rate, also as assessed by MRD. The long term efficacy of this regimen remains to be established by longer follow-up. Disclosures: No relevant conflicts of interest to declare.

Abstract Abstract 2791 Introduction: Elderly mantle cell lymphoma (MCL) patients (pts) do not benefit from dose-intensive chemotherapy upfront.1 The GOELAMS group recently demonstrated that a regimen comprising Vincristine/Adriamycine/Dexamethasone plus Chlorambucil (VAD+C) was well tolerated, had a good efficacy/toxicity profile and induced similar PFS than R-CHOP (median PFS between 16 to 18 months2,3,4). Additionally, it has been shown that bortezomib (Velcade®), with or without Rituximab has efficacy in relapsed/refractory MCL patients5,6. These data prompted, our group to conducte a phase II prospective non randomized clinical trial evaluating the combination of Velcade plus Rituximab/Adriblastine/Dexamethasone/Chlorambucil (RiPAD+C) as a first line therapy for elderly MCL patients. Aims: To evaluate the overall response rate (ORR) and toxicity after 4 cycles of RiPAD+C regimen (main objective) and to evaluate prognostic factors for survival (secondary objective). Protocol: RiPAD+C : Rituximab 375 mg/m2 on d1 (and d8 for cycle 1); PS 341, Velcade® 1.3 mg/m2 on d1, 4, 8 and 11; Adriblastine 9mg/m2/d as a continuous infusion for 4 days; Dexamethasone 20 mgx2/d from d1 to d4; Chlorambucil 12 mg/d, d20 to d29. Repeat cycles every 35d. After 4 cycles, responding pts (Cheson 1999 criteria) received 2 additional cycles for a maximum of 6. Patients and methods: Inclusion criteria: All untreated elderly (65 to 80 years old) MCL patients (including blastoid forms) presenting with a stage II to IV disease with a good PS (ECOG<3) were eligible. Histologic samples were centrally reviewed and Ki67 expression was evaluated for each sample according to the European guidelines7. Results: Population: from June 2007 to December 2009, 39 pts were enrolled in the study with a majority of males (n=30). Median age at diagnosis was 72 years [65-80]. All patients had stage III/IV disease and PS was ≥2 in 5 cases (15%). Elevated serum LDH were observed in 47% of cases. According to the MIPI, 28 patients (80%) had an intermediate or high score. Eleven (30%) patients presented with a blastoid variant and Ki67 staining was superior to 30% in 12 cases (37%). Toxicity: A total of 195 courses have been performed. Fourteen hospitalization (median duration = 7 days [1 and 55]) due to toxicity were necessary involving 12 pts (34%). Seven pts (18%) experienced grade 3 peripheral neuropathy. ten (25%) pts required blood transfusions for a total of 8 red blood cells and 14 platelets transfusions. Response after 4 cycles: ORR was 80% (n=31) including 51% of CRs. Eight pts discontinued the treatment before reaching cycle 4, two of them for toxicity reasons. Six patients (15%) were refractory or in progression. Response after 6 cycles (n=25; 64%): ORR was 74% including 20 pts in CRs (59%). Survival: With a median follow-up of 24 months, 27 pts are still alive. Two pts died of toxicity (severe sepsis) and 10 pts progressed. The median PFS is 26 months and the median OS has not been reached yet. According to the MIPI score, no differences in PFS were between pts with low and int/high scores. Conversely, the recently described Goelams index2 stratified pts with a low score (normal LDH, Ki67≤26%, PS≤1, and no B symptoms) from patients with an int/high score (p=.055). Conclusion: The results of the current phase II trial indicate that the RiPAD+C regimen, integrating bortezomib, is feasible and well tolerated as a first line therapy in elderly MCL pts. Historical comparisons suggest that this regimen compares favourably to the classical R-CHOP regimen in terms of response rates and duration.

Eskelund et al examined clonal hematopoiesis (CH) in a cohort of patients with mantle cell lymphoma (MCL) treated with first-line chemotherapy and autologous stem cell transplantation. In young, good-risk MCL patients, CH after first-line therapy arises almost entirely from preexisting clones, stabilizes after a period of expansion posttransplantation, and does not negatively impact survival.
