Abstract Introduction The currently accepted standard of care for patients with relapse/refractory NHL is dose escalation and consolidation with Stem Cell Transplantation. The ability to predict those patients who may benefit or not from this approach would be beneficial. Whole-body Positron Emission Tomography using 18F-fluorodeoxyglucose (FDG) is now recognised to have predictive ability in those patients at high risk of relapse and shortened overall survival in De novo High grade lymphoma. In the salvage setting it is unknown whether the appearance of PET scan after 1 cycle of salvage treatment may predict similarly for outcome post transplant and whether early scanning is indicated before cycle 2 salvage chemotherapy. Aim: The aim of this study is to assess whether the PET-CT after one cycle or two cycles of dose escalation was predictive of outcome in patients with relapse/refractory NHL. Methods: We collected the data prospectively of all patients with relapsed or refractory aggressive NHL or HD treated in our institution over a 2 year period who were considered suitable for salvage therapy followed by Stem Cell Transplantation. We identified 14 male and 10 female patients with a mean age of 44 years (range 24–66). 12 patients had disease refractory to first line treatment and 12 patients had relapsed disease with a median interval from completion of treatment to relapse of 20 months (range 2–60). All patients were initially treated with DHAP as salvage therapy.22/24 patients proceeded to a stem cell transplant. 16/22 had an autologous transplant conditioned with BEAM and 6/22 had allogeneic transplants.FDG PET- CT scans were performed (all positive) prior to salvage chemotherapy and then assessed after 1 cycle of salvage chemotherapy and then after the second cycle using a 5 point visual scoring system as follows: CMR - no uptake at disease sites, MRU1 – visually uptake below level of mediastinum, MRU2 – visually between mediastinum and liver Stable/persistent metabolically active disease and Progressive disease (either new lesions or increased uptake in the same sites. Results FDG-PET Data was collected from 24 patients (14 male and 10 female) and read by two independent observers. The patients had the distribution shown in table: Visual response criteria Appearance PET 1 : Patient Numbers Appearance PET 2 : Patient Numbers CMR 1 6 MRU1 0 2 MRU2 1 3 Stable/persistent 16 5 Progressive 6 8 The median progression free survival of the patients with progression after one cycle of chemotherapy was 1.5 months with 3/6 deaths. Progression on PET1 was seen only in refractory cases pre salvage and was associated with a significant risk of relapse (p=0.014). The median progression free survival of the patients with stable disease after one cycle was 9.5 months. After two cycles of chemotherapy the median progression free survival of patients with CMR/MRU1/MRU2 was 9 months, compared with stable disease of 8 months and progressive disease 6 months. Conclusions: Patients with progressive disease on PET after one cycle of chemotherapy have a poor outcome with 50% early deaths and would be candidates for targeted/experimental therapies. Longer follow up will be required to assess the significance of stable or persistent disease on PET after one cycle and two cycles of salvage chemotherapy.

Abstract Background: There have been many advances in treatments for multiple myeloma (MM). Recently, novel agents such as thalidomide, bortezomib, and lenalidomide have been developed for myeloma treatment. thalidomide was the first novel agent introduced that improved the overall response rate (ORR) and prolonged survival in transplant eligible or ineligible patients with multiple myeloma. It was first confirmed that thalidomide was active in patients with relapsed and/or refractory MM; since then, thalidomide has become an important part of MM treatment, as initial therapy for previously untreated patients, as maintenance therapy following definitive treatment, and as salvage therapy. Until now, the efficacy of thalidomide maintenance has been controversy in some studies. The purpose of this study was estimate necessity of thalidomide maintenance for improving survival in transplantation eligible patients with MM in real clinical fields. Methods: Data from patients at thirteen university hospitals in South Korea between December 2005 and May 2013 were collected retrospectively. All included patients were treated with induction chemotherapy followed by autologous stem cell transplantation (ASCT) and then with or without maintenance. The included patients were treated with thalidomide based regimens (TD;128 (50.6%), CTD; 96 (37.9%), TAD; 11 (4.3%)), mostly or other conventional regimens such as vincristine, doxorubicin and dexamethasone (VAD; 10 (4.0%), and others; 8 (3.2%)) as induction chemotherapy. And then patients received ASCT. However, patients were excluded underwent tandem ASCT or Allogeneic stem cell transplantation. The number of patients treated with thalidomide maintenance for more than six months after ASCT were 74 (29.2%) without maintenance were 179 (70.8%). The differences of survival were estimated in two groups which were defined to include patients treated with or without thalidomide maintenance. Patients who suffer from progression or relapse after ASCT were received salvage chemotherapy such as bortezomib based or other novel agents based regimen. The progression free survival (PFS) was defined duration from the date of starting induction chemotherapy to the date of disease progression, relapse, or death from any causes after ASCT. The definition of overall survival (OS) was calculated from the date of diagnosis to the date of death from any causes or final follow-up date. The postrelapse survival (PRS) was defined duration from the date of relapse after ASCT to the date of disease progression, relapse, or death from any causes. Results: The median age of the 253 patients was 57 years (range, 33-75 years) and the male to female ratio was 1.07:1.0. The response rates before ASCT were following: CR or stringent CR (sCR) in 93 (36.7%), VGPR in 63 (24.9%), PR in 86 (34.0%), and < PR in 7 (2.8%). The reason for the higher ORR in this study compared to other studies was that it included patients who were treated with thalidomide induction chemotherapy and who underwent ASCT. Most of these patients achieved more than PR or PR because the South Korean national health insurance only allowed ASCT in such patients. The differences of 3-year PFS of patients with or without maintenance were 66.1% vs 43.0%, p=0.003. The 3-year OS were 91.7% vs 84.5%, p=0.091. And the differences of PRS were not shown in two groups (11.63 vs 10.00 months, p=0.790). Conclusion: Patients treated with thalidomide maintenance after ASCT were presented higher PFS but not shown higher OS. However, long term use of thalidomide as maintenance therapy was not interfere with efficacy of salvage chemotherapy in patients suffered from progression or relapse after ASCT. So, we suggest that thalidomide maintenance might be useful for improving survival by lowering relapse or progression rates and not interfere with efficacy of salvage chemotherapy in real clinical field. In the future, further prospective studies will be needed to confirm the role of thalidomide maintenance therapy for prolonged survival in patients with MM who are treated with novel agents such as thalidomide, bortezomib, or lenalidomide.

PURPOSE: To study the prognostic value of plasmablastic morphology after autologous stem-cell transplantation for relapsed or primary refractory myeloma. PATIENTS AND METHODS: Seventy-five patients were studied. Investigators blinded to the clinical details of the individual cases reviewed bone marrow aspirate slides to determine plasmablastic classification. Plasmablasts were defined using strict, well-described criteria. Plasmablastic morphology was considered to be present (plasmablastic myeloma) when 2% or more plasmablasts were present in the plasma-cell population. RESULTS: Patients underwent transplantation 5 to 88 months (median, 20 months) after the initial diagnosis of myeloma. Twenty-eight percent of patients had plasmablastic morphology. A significantly greater proportion of patients with plasmablastic morphology had abnormal cytogenetics compared with those with nonplasmablastic classification (73% v 31%, respectively; P = .003). The overall survival rate measured from the time of transplantation was significantly worse in patients with plasmablastic morphology compared with those without (median survival time, 5 months v 24 months, respectively; P < .001). Progression-free survival time was shortened also, with a median time of 4 months compared with 12 months, respectively (P < .001). In the multivariate analysis, plasmablastic classification was the most powerful prognostic factor after transplantation for both overall (P = .001) and progression-free survival rates (P < .001). We also identified three risk groups based on plasmablastic morphology: plasma-cell labeling index, lactate dehydrogenase, and cytogenetics. The median overall survival time was 38 months when none of these factors was abnormal, 17 months with one abnormal factor, and 8 months with two or more abnormal factors (P < .001). CONCLUSION: Plasmablastic morphology is a powerful independent predictor of poor survival rate after autologous stem-cell transplantation for relapsed or primary refractory myeloma.

Abstract The prognosis for patients with mantle cell lymphoma (MCL) treated with conventional chemotherapy remains poor. Dose escalation and stem cell transplantation has been increasingly employed in an attempt to improve the outcome in these patients. However, due to the advanced age of many patients with MCL, high dose therapy and allogeneic stem cell transplantation is particularly hazardous. Reduced intensity allogeneic transplantation (RIT) may reduce the toxicity of allogeneic stem cell transplantation, facilitate allogeneic engraftment and graft versus lymphoma reactions. However, the results reported to date with this treatment modality have been based on small numbers of patients and provide conflicting results. We have therefore analysed the outcome of a large cohort of patients with MCL reported to the EBMT registry who have undergone RIT. A total of 144 patients (123 male) with a histological diagnosis of MCL were reported by 81 centres. The median age at transplant was 49 years (range 28–68 years) and the median time from diagnosis to transplant was 25 months (range 0.25–13.2 years). The patients had received a median of 2 (range 1–5) lines of prior chemotherapy and 60 (42%) had undergone a prior high dose procedure. At the time of RIT 100 patients had chemosensitive disease, 22 chemoresistant disease and 22 had untested relapse. Patients underwent conditioning with reduced intensity regimens prior to transplantation with allogeneic peripheral blood stem cells (122), bone marrow (20) or both (1). Fully matched sibling donors were used in 109 cases, matched unrelated donors in 21 and 9 patients received mismatched stem cells. 123 of 126 patients assessable for engraftment demonstrated sustained engraftment. With a median follow up of 9 months 84 patients remain alive and 60 have died (15 from progressive disease and 45 from non-relapse mortality). The transplant related mortality (TRM) was 12% at 100 days but by Kaplan-Mier analysis the TRM was 35% at 1 year and 50% at two years. In univariate analysis there was a non-significant trend to a higher TRM in patients with chemoresistant disease (p=0.067) and those with a prior transplant (p=0.062). Patient age and the number of lines of prior therapy had no impact on TRM. At two years following transplant 57% of patients had evidence of disease relapse or progression which was significantly worse in those with chemoresistant disease prior to transplant (p=0.02). The overall survival (OS) at 1 year and 2 years was 55% and 31% respectively and was worse for patients with chemoresistant disease. The progression free survival (PFS) at 1 and 2 year was 43% and 26% respectively. Only disease status at transplantation predicted for a worse PFS. Acute GVHD (grade II-IV) developed in 52 patients and chronic GVHD in 23 patients. Although the early transplant related toxicity is low there remains a significant TRM following RIT for MCL and consequently a low progression free survival. Patients with chemoresistant disease have a particularly poor outcome.

Abstract Abstract 4554 High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is currently standard treatment for younger patients with multiple myeloma, resulting in improved survival and response rate compared to conventional chemotherapy. Disease relapse, however, remains almost inevitable and thus the role of two successive (tandem) autologous stem cell transplants has been evaluated in chemorefractory patients as a means of prolonging duration of disease response. We retrospectively analysed the results of nine patients with chemorefractory disease treated at a single UK institution who received tandem ASCT between January 1998 and February 2009. There were six men and three women. Median age at diagnosis was 56 years (range, 42–65 years). Paraprotein isotype was IgG in eight patients and IgA in one patient. Median serum paraprotein level was 41g/L (range 12–73g/L) at presentation. At time of 1st transplant six patients were in stable disease (SD) and three had evidence of progressive disease. Conditioning melphalan dose was 140mg/m2 in all but two patients who received 110mg/m2 and 200mg/m2. Median time between transplants was 3.7 months (range 2.3–6.4 months) with PR and SD being observed in 2/9 and 7/9 patients at time of 2nd transplant. None of the patients reached complete response (CR). One patient received melphalan 140mg/m2 prior to 2nd transplant. The remaining patients received melphalan 200mg/m2. Median follow up after tandem transplant was 54.3 months (range 15.6 –143.6 months). No treatment related mortality was reported. At the time of analysis, six patients were still alive and under follow up with an overall survival (OS) figure for the group of 52% at 10 years from diagnosis (Figure 1). Median progression free survival (PFS) was 20 months from 2nd transplant (range 6.7–62.6 months) (Figure 2). Tandem autologous stem cell transplant in chemorefractory patients has resulted in overall survival similar to autologous stem cell transplant in chemosensitive patients and should be considered in patients with chemorefractory disease.
