Abstract Abstract 3108 Background: Functional imaging is widely used for response assessment in Hodgkin lymphoma (HL) patients treated for first line in addition to conventional imaging (magnetic resonance imaging, computed tomography). Insufficient information is available on the prognostic value of 18Fluorodeoxyglucose positron emission tomography (FDG-PET) status in pediatric and adolescent patients with recurrent HL undergoing high-dose therapy and autologous stem cell transplantation (HDT/ASCT). Patients: Thirty-five patients (20 male, 15 female) with classical HL who received first-line therapy according to the GPOH HD-2002 study (n=31), GPOH HD-2002/VECOPA study (n=3) or during interim observation (n=1) and subsequently relapsed before the start of the EuroNet-PHL-C1 trial were analyzed. Ten patients progressed during first-line therapy, 23 patients had an early relapse and in two patients disease recurred late (>12 months after end of therapy). Patients received salvage therapy mainly based on IEP (ifosfamide, etoposide, prednisone) and ABVD (adriamycine, bleomycin, vinblastine, dacarbazine) regimens according to treatment recommendations followed by HDT/ASCT. Tandem transplantations were excluded and follow-up of surviving patients had to be at least six months. FDG-PET was reviewed centrally based on a quadrinomial scale and was assessed before relapse treatment, after one or two salvage therapy cycles (early response assessment [ERA], n=33 patients) and/or immediately before ASCT or followed by one more cycle prior to HDT (late response assessment [LRA], n=23 patients). Results: Median age of the 35 patients at relapse was 15.7 years (range, 5.5 to 17.5) and 16.9 years (range, 6.5 to 19.0) at ASCT. At a median follow-up of 59 months, 29 patients were alive. The overall survival rate at 4 years was 82.4±6.5%. Eight patients relapsed following HDT/ASCT. The proportion of patients without second failure at 4 years was 77.0±7.1%. At ERA, 19 patients were PET negative and 14 patients were PET positive. PFS of ERA-PET-negative patients at 4 years is 94.7±5.1% compared to 56.3±13.5% in PET-positive patients (P =.009). PFS of LRA-PET-negative patients at 4 year was 94.1±5.7% vs 44.4±22% for PET- positive patients (P =.014). In addition, five of ten patients with progressive disease could be successfully salvaged. Six patients with subsequent relapse underwent allogeneic SCT; two of these patients are alive. Conclusions: Overall survival of this cohort is favorable, even patients with progressive disease have a fair chance for second long term remission. ERA-PET-negative patients have an excellent prognosis after salvage treatment including HD-chemotherapy and autologous stem cell transplantation. New options may be required for those patients who remain PET positive prior to HDT. Disclosures: No relevant conflicts of interest to declare.

Abstract Introduction: Most patients with advanced-stage follicular lymphoma(FL) cannot be cured by conventional chemotherapy and have median survival of 7 to 10 years. High-dose chemotherapy (HDT) supported by autologous stem cell transplantation(ASCT) gives a survival benefit for patients with aggressive lymphoma. Recent several multicenter studies have shown that clinical and molecular remissions can be attained in patients with FL receiving intensified high-dose sequential chemotherapy and autografting. We have reported the efficacy and safety of high-dose bi-weekly THP-COP with G-CSF support (HDBW-TCOPG) for non-Hodgkin’s lymphoma. Therefore, we performed a pilot clinical trial to evaluate the efficacy and toxicity of HDBW-TCOPG followed by HDT with ASCT as first-line therapy in patients with advanced-stage FL. Patients and methods: Between August 1998 and December 2003, 10 Japanese patients with previously untreated FL from whom informed consent was obtained were included in this single-center pilot study. Median age was 48 years. All patients had stage 3 or 4 disease, aaIPI LI 8 and HI 2. Histological subtypes of FL included grade 1 4; grade 2 4; grade 3a 2. HDBW-TCOPG consisted of pirarubicin 70 mg/m2 on day 1; cyclophosphamide 1000 mg/m2 on day 1; vincristine 1.4 mg/m2 on day 1; predonisolone 50 mg/m2 from day 1 to 5; lenograstim 2.0 mg/kg/day from day 3. Five patients who enrolled after rituximab was approved for indolent B-cell lymphoma in Japan received induction therapy combined HDBW-TCOPG with rituximab 375mg/m2 on day -2 (R-HDBW-TCOPG). Six cycles were administered at intervals of two weeks. PBSC were collected during the later cycles of HDBW-TCOPG or on the recovery of high-dose etoposide regimen (500mg/m2 for 3 days) administered after the completion of HDBW-TCOPG. Leukaphereses were performed until a minimum of 2.0x106/kg CD34+ cells had been collected. The conditioning regimen consisted of ranimustine 200mg/m2 on day-7 and -2; paraplatin 300mg/m2 on day -6, -5, -4, -3; etoposide 500mg/m2 on day −5, −4, −3; cytarabine 2.5 g/m2 every 12 hours on day −2, −1 (MCE-CA regimen) in 2 patients or cyclophosphamide 50mg/kg on day −2, −1 (MCEC regimen) in 8 patients. Results: Sufficient numbers of PBSC were collected in 5 of 7 patients mobilized with HDBW-TCOPG and in all 5 patients with high-dose etoposide. The median time to reach total number of leukocytes of 1.0 x109/l was nine days (range 8–11). All 10 patients who were in PR at the end of HDBW-TCOP(G) achieved CR post APBSCT. After a median follow up of 36.6 months (range 7–66 months) PFS and OS are 90% and 90%, respectively, for all patients. One patient developed secondary myeloid leukemia with t(3;21) and died at 35 months after APBSCT without signs of recurrence of lymphoma. Another patient who relapsed at 35 months after transplantation. IgH or BCL2 rearrangement was detected by PCR analysis prior to therapy in three patients and one of them still showed detectable disease after HDBW-TCOPG induction. However, all three patients demonstrated MRD negativity after HDT with ASCT. Conclusion: HDBW-TCOPG as induction therapy followed by HDT with ASCT is feasible for advanced-stage FL with acceptable toxicity, and this short term highly intensified therapy may induce cure of the disease by minimizing MRD, but longer follow up is needed to evaluate the impact on survival.

Abstract Recommended first-line therapy for patients with chronic phase (CP) CML is imatinib mesylate (IM). Although IM induces complete cytogenetic responses (CCR) in the majority of patients, disease often remains detectable by Q-RT-PCR, likely reflecting stem cell persistence. Furthermore, primary and acquired resistance to IM have led to concerns about response durability. Allogeneic stem cell transplantation (SCT) remains the only curative option and with reduced intensity conditioning (RISCT) is less toxic and may be offered to a broader patient group. Our novel approach used IM to establish disease control (CCR) in patients with newly diagnosed CP CML prior to RISCT (fludarabine/melphalan/MabCampath). Prophylactic escalating DLI was given for residual disease. 18 patients (4 centres) were recruited between 2001 and 2006. Of these, 3 received myeloablative SCT, 2 for progression to blast crisis prior to SCT and the third for failing to reach a major cytogenetic response. 15 patients with a median age of 39y (21–56y) received sibling RISCT. Hasford scores were 38% low, 54% intermediate and 8% high risk. EBMT risk scores were 1–2 (13 patients) and 3–4 (2 patients). 5 patients required IM dose escalation to achieve CCR prior to RISCT. Follow-up data extends to a median of 31 (12–61) months (m) post RISCT. The RISCT procedure was well tolerated with rapid engraftment and short in-patient stays. 53% had infective episodes post RISCT, including CMV reactivation (86% patients at risk), EBV+ post transplant lymphoproliferative disease (2 patients) and PCP (1 patient). 1 patient developed aGvHD (grade III) and 8 cGvHD (6 limited, 2 extensive). DLI was given to 13 patients (87%), 6 for elevated Bcr-Abl, 4 for mixed chimerism and 2 for both. The median total dose was 0.65 × 107CD3+cells/kg (0.1–6.65 × 107cells/kg) in a median of 2 infusions. GvHD was seen in 6 of 12 patients receiving DLI (50%). IM was required in 4 patients with residual disease and all discontinued IM once disease control was re-established (4–13m of IM). 1 of 15 transplanted has died (at 12m with GvHD and infection). Of surviving patients median Bcr-Abl measurements fell as follow-up progressed. 8 patients currently have sustained undetectable Bcr-Abl. 7 of these 8 received DLI, the other had GvHD. The interval between last DLI and first proof of disease eradication was median 2m (range 1–28m). Only 2 of these 8 patients received IM post-transplant. In this study, the patients receiving RISCT were in early CP with a CCR to IM. It is likely that the majority would have maintained CCR if not offered transplantation. However the number of patients who achieved undetectable Bcr-Abl following RISCT and DLI compares favourably with the response expected with IM alone. The patients have tolerated the transplant procedure well and are currently off all treatment for CML. Regular monitoring remains necessary, however if relapse occurs it should be DLI responsive. Currently IM is the accepted first line therapy in the majority of patients however we would highlight the importance of RISCT in selected groups and believe our approach is effective and well tolerated.

The role of high-dose therapy (HDT) followed by autologous stem cell transplantation (ASCT) in the treatment armamentarium of aggressive B- and T-cell non-Hodgkin lymphoma (NHL) is still a matter of debate. In the pre-Rituximab era, the PARMA study demonstrated the superiority of HDT/ASCT over conventional salvage chemotherapy in chemosensitive, relapsed patients. Subsequently, HDT/ASCT has become a standard approach for relapsed NHL. With the advent of Rituximab in the landscape of NHL, transplantation as part of first-line therapy has been challenged. However, no benefit in terms of disease-free or overall survival of HDT/ASCT over standard therapy was shown when Rituximab was added to both arms. Moreover, the superiority of HDT/ASCT over conventional salvage therapy in patients relapsing from first-line therapy including Rituximab was not confirmed. From these disappointing results, novel strategies, which can enhance the anti-lymphoma effect, at the same time reducing toxicity have been developed, with the aim of improving the outcome of HDT/ASCT in aggressive NHL.In T-cell lymphoma, few publications demonstrated that consolidation of complete remission with HDT/ASCT is safe and feasible. However, up to one-third of patients may never receive transplant, mostly due to progressive disease, and relapse still remains a major concern even after transplant.

Abstract Abstract 3987 Background: Autologous stem cell transplantation (ASCT) is the gold standard as first-line treatment in young patients with multiple myeloma (MM). Prognostic factors have been usually related to patient characteristic and disease stage. Few investigations on the pattern of relapse or progression after ASCT have been addressed. The differentiation of serological or asymptomatic progression versus clinical relapse requiring treatment is also an important issue. The aim of this study was to investigate the characteristics at the time of relapse or progression in patients with MM who received ASCT as part of a first-line treatment. Patients and Methods: Two-hundred and eleven patients underwent melphalan-based ASCT at our institution during the last 18 years. Of these, 170 patients (87M/83F; median age 56 years, range 25 to 70) who achieved at the least a minimal response (PR) after no more of two induction lines before ASCT are the basis of this study. Initial baseline demographics, clinical and laboratory data at relapse or progression, and information concerning treatment and follow up were collected. The M-protein heavy-chain isotype was IgG (57%), IgA (23%), light chain only (14%) and others (3.5%). Only 2.5% were oligosecretory MM. Extramedullary plasmacytomas (EMP) were observed in 37 out of 170 patients (22%) at diagnosis. The ISS stage was I (45.3%), II (26.5%), III (18.8%) and unknown (9.5%). 12.6% of the patients had a serum creatinine level ≥2 mg/dL and 16.2% had hypercalcemia. The median follow-up for alive patients was 3.9 years (range 4 months to 18 years). Response, relapse, and progression were defined according to European Blood and Marrow Transplantation (EBMT) criteria. Results: Median PFS was 3.3 years (CI 95% 2.7 to 3.9 years) and the median OS of 6.8 years (CI 95% 3.9 to 9.6 years). 47.7% of the patients achieved a complete remission (CR). As of December 2011, 93 patients (54.7%) had relapsed or progressed after ASCT. 37 out of the 93 patients (40%) had relapsed from CR, while the remaining 60% had progressed from PR. A serological or asymptomatic relapse/progression was as frequent as a symptomatic one (49.5% vs. 50.5%, respectively), the latter requiring immediate treatment in the median of a month. Patients with serological relapse/progression had a significantly longer OS than those requiring immediate treatment (p=0.002)(Figure). The main clinical reasons to start myeloma therapy were anemia (43%), new bone lytic lesions (36%), EMP (23.7%), bone pain (14.4%), renal insufficiency (12.2%) and/or hypercalcemia (9%). 22 of the 93 patients (24%) relapsed/progressing patients had EMP at the time of progression. In three of them, the extramedullary involvement was the only criteria of progression. The presence of EMP at diagnosis was significantly associated with extramedullary disease at relapse (p=0.001). In fact, 12 out of the 22 patients (54.5%) with EMP at relapse had also EMP at the time of diagnosis. Median time between serological relapse or progression and treatment was of only 5.6 months (range 0 to 5.6 years). However, in 12 out of 46 patients (26%) with serological relapse/progression, treatment was not initiated within first two years. Finally, time to next treatment was significantly longer in patients relapsing from CR (median 2.85 years; CI 95% 2.1 to 3.6) vs. those progressing from PR (median 1.65 years; CI 95% 1.1 to 2.2) (p=0.017). Conclusion: After ASCT, serological or asymptomatic relapse/progression is observed in about one half of the patients. The treatment-free interval in these patients is longer in patients relapsing from CR than in those progressing from PR. Patients with symptomatic relapse/progression have shorter OS. Extramedullary involvement is frequent, being the highest risk in patients with EMP at diagnosis. Finally, relapse/progression with extramedullary disease only is rare. Disclosures: No relevant conflicts of interest to declare.

Abstract Background: The aggressive approach to first-line treatment of multiple myeloma (MM) incorporating autologous stem cell transplantation (ASCT) remains widely prevalent, although it is not without controversy in the current era of novel effective agents. Some trials and meta-analysis comparing ASCT to non-myeloabaltive standard therapy or delayed ASCT have failed to show an overall survival (OS) difference between the two arms [Fermand et al. Blood 92:3131-3136 (1998); Koreth et al. BBMT 13:183-196 (2007); Kumar, et al. Cancer 118(6):1585-92 (2012)]. On the other hand, analysis of transplant-eligible patients receiving lenalidomide and dexamethasone induction on the E4A03 trial and then either undergoing ASCT or continuing lenalidomide and dexamethasone showed that ASCT conferred improved OS (Blood 2010;116:38a). This controversy lead us to design a phase II clinical trial comparing continuous lenalidomide and dexamethasone (Ld) versus ASCT followed by lenalidomide maintenance, in patients responding to four cycles of Ld. Methods: Patients with newly diagnosed symptomatic MM as defined by IMWG criteria were enrolled. Patients deemed to be in urgent need of aggressive therapy (e. g. symptomatic bone disease, acute renal failure, hyperviscosity syndrome, etc…) were not eligible. Patients received induction with lenalidomide (L) 25 mg PO daily on days 1-21, and dexamethasone (d) 40 mg PO daily on days 1,8,15, and 22 of a 28-day cycle with standard prophylaxis. Patients with POD during induction or SD after four cycles of Ld were taken off study. All other patients had stem cells harvested after four cycles of Ld and were randomized to either the continuous (Ld) arm (L at the last tolerated dose during induction, continued indefinitely until progression or toxicity; and d at 20mg weekly for one year) or the ASCT arm (using melphalan conditioning followed by L maintenance started three months post-ASCT at 10mg daily, escalated to 15 mg daily six months post-ASCT and continued indefinitely until progression or toxicity). Results: Fifty seven patients have been registered to the trial. Two patients did not initiate therapy, one because of a concurrent diagnosis of amyloidosis and the other due to aggressive disease mandating alternative therapy according to the treating physician. At this time, four patients are still receiving induction therapy and are not available for response assessments. Among the 51 remaining patients, the response to initial induction therapy includes 12% CR (n=6), 2% uCR (n=1), 4% nCR (n=2), 14% VGPR (n=7), 51% PR (n=26), 6% SD (n= 3), 4% POD (n=2), and 8 % inevaluable (n = 4 who did not receive at least two cycles of Ld). Thirteen patients were removed from the trial prior to randomization due to POD (n=2), SD after four cycles (n=3), toxicity (n=4), physician discretion (n=2), and withdrawal of consent (n=2). Among these 13 patients, one was lost to follow-up, two continued lenalidomide therapy off protocol (one patient refused ASCT, and one patient had inadequate stem cell collection), and 10 proceeded to alternative induction. All 12 patients achieved a response [25 % CR (n=3), 42 % VGPR (n=5), and 33 % PR (n=4)]; 10 patients proceeded to ASCT without event. Thirty-eight patients were randomized, 20 to Ld and 18 to ASCT. Improvement of response by at least one level occurred in 45% and 65% of patients on the Ld and ASCT arms, respectively. The median follow-up for all surviving patients from time of randomization is 38.3 months. The 1- and 3-year PFS in the Ld arm were 100% and 66%, respectively. The 1- and 3-year PFS in the ASCT arm were 89% and 68%, respectively. The 2- and 3-year OS in the Ld arm were 100% and 92%, respectively. The 2- and 3-year OS in the ASCT arm were 100% and 85%, respectively. Considering the entire population of 51 patients, with a median follow-up of 38 months, the median PFS has not been reached. Conclusions: This interim analysis, with relatively short follow-up, suggests that in transplant-eligible patients responsive to Ld during induction, continuous Ld results in similar PFS and OS compared to patients who undergo ASCT followed by L maintenance. Furthermore, this overall approach based on response-adapted treatment results in 100% of patients reaching at least PR at completion of first-line therapy. The trial remains ongoing.

Abstract INTRODUCTION: high-dose chemotherapy (HDC) followed by autologous hematopoietic stem cell transplantation (ASCT) is a curative option for relapsed diffuse large B-cell lymphoma (DLBCL). However, relapse within 1 year after diagnosis, previous therapy with rituximab and secondary IPI = 2 or 3 have been associated with unsatisfactory outcome even after ASCT, thus the better treatment of these patients is matter of debate and efforts are ongoing in order to improve survival. METHODS: on a total of 146 DLBCL patients receiving ASCT, we identified 78 adult patients who had responsive but still measurable disease after first-line therapy or relapsed/progressive disease with one or more adverse features as specified above. All patients were >18 years old and received ASCT at our institution. Patients were grouped according to the administered treatment: 1) n= 21 patients were in response but not in complete remission (CR) after first-line and received HDC and ASCT; 2) n= 48 patients had refractory or relapsed disease and received salvage chemotherapy followed by HDC and ASCT (n=46 single ASCT, n=2 double ASCT); 3) n=9 patients received salvage therapy then tandem autologous-allogeneic SCT due to the presence of any of the above mentioned adverse features. For all patients, salvage chemotherapy was mostly VIHA or DHAP with the addition of rituximab. Most used regimens of HDC were Melphalan 200 mg/mq or BEAM. Among the nine patients undergoing tandem auto-allo, eight received Melphalan 200 mg/mq and one BEAM; allogeneic donors were either HLA-identical siblings (n=3), unrelated (n=1) or haploidentical ones (n=5). All conditioning regimens before allogeneic SCT were reduced-intensity or nonmyeloablative. RESULTS: at last follow-up, survival rate is 57% for group 1 (12 alive out of 21 patients), 27% for group 2 (13/48) and 67% for group 3 (6/9). Cause of death in this last group was disease relapse/progression for all 3 cases (2 patients were in partial remission (PR) before allo, 1 in CR). Disease status before allogeneic SCT for the 6 alive patients was CR (n=3) and PR (n=3). Their follow-up is +8, +24, +26, +40, +45 and +70 months since ASCT. Of note, survival rate was 74% for the 47 patients receiving HDC and ASCT in first CR (candidated upfront to ASCT due to high-risk IPI at diagnosis) and 62% for the 21 relapsed patients who did not present any of the above mentioned adverse features at relapse. Those two groups were taken from the same initial sample of 146 patients. CONCLUSION: for patients affected by relapsed DLBCL with one or more adverse prognostic features, administration of allogeneic SCT after ASCT as a tandem strategy provides promising results compared with patients receiving ASCT alone and deserves further investigation, especially taking into account the rapid expansion of platforms using T-cell replete haploidentical grafts. Upfront HDC followed by ASCT appears to be a valid option for those patients in PR after first-line therapy, with a 57% survival rate in our series.

Abstract Introduction: First-line autologous stem cell transplantation (SCT) is an accepted therapy for mantle cell lymphoma (MCL). We have recently shown that 2 standard doses of rituximab significantly improve the outcome of TBI-based upfront SCT in MCL when administered peritransplant (Haematologica 92:42; 2007). The purpose of the present retrospective analysis was to compare this approach with alternative rituximab-based strategies. Patients and treatment strategies: 34 consecutive patients treated in KI-HH received 3–6 cycles of CHOP prior to stem cell mobilization with Dexa-BEAM (n=20) or DHAP (n=14), followed by TBI-cyclophosphamide-rituximab myeloablation and SCT (CHOP/R-TBI-CY group). Patients treated in HD received 3–8 cycles of R-CHOP for cytoreduction (n=28) and mobilization (n=23; the remaining 5 patients were mobilized with R-DHAP/HAM) followed by BEAM and SCT (R-CHOP/BEAM group). 12 patients of this group received additional rituximab maintenance after SCT. Results: With a median follow-up of 38 months (9–111), estimated 4-year progression-free survival (PFS) from diagnosis of patients treated with CHOP/R-TBI-CY and R-CHOP/BEAM was 83% and 72% (log rank, p=.38), respectively. Of note, with a median follow-up of 30 months (14–57) there was no relapse in the 12 pts receiving maintenance therapy with rituximab, translating into a significantly better 4-y PFS in patients receiving R-CHOP/BEAM with rituximab maintenance vs those without (100% vs. 56%; p=.021). The PFS difference between the R-CHOP/BEAM group and the CHOP/R-TBI-CY group became borderline significant after omitting the rituximab maintenance patients (p=.055). Conclusions: In advanced-stage MCL, addition of rituximab improves disease control provided by first-line SCT. Whereas the exact dose and timing of rituximab administration remains to be settled, prospective investigation of post-transplant rituximab maintenance appears to be particularly promising.

Background In Ontario, no clearly defined standard of care for the management of mantle cell lymphoma (mcl) has been developed, and substantial variability from centre to centre is evident. This guidance document was prompted by the need to harmonize practice in Ontario with respect to first-line, conditioning, and post transplantation maintenance therapy for patients newly diagnosed with transplantation-eligible mcl. Methods The medline and embase databases were systematically searched from January 2013 to January 2020 for evidence, and the best available evidence was used to draft recommendations relevant to first-line therapy, autologous stem-cell transplantation, and post-transplantation maintenance in the management of transplantation-eligible newly diagnosed mcl. Final approval of this guidance document was obtained from the Stem Cell Transplant Advisory Committee. Recommendations These recommendations apply to all cases of transplantation-eligible newly diagnosed mcl:■ Alternating cycles of r-chop (rituximab plus cyclophosphamide–doxorubicin–vincristine–prednisolone) andr-dhap [rituximab plus dexamethasone–high-dose cytarabine–cisplatin] is the recommended first-line treatmentfor symptomatic patients newly diagnosed with mcl before autologous stem-cell transplantation (asct).■ Rituximab plus hyperfractionated cyclophosphamide–vincristine–doxorubicin–dexamethasone (r–hypercvad),alternating with methotrexate and cytarabine, is not recommended for the treatment of patients with newlydiagnosed mcl.■ beam (carmustine–etoposide–cytarabine–melphalan), beac (carmustine–etoposide–cytarabine–cyclophosphamide),and total-body irradiation–based regimens are reasonable conditioning options for patients with mcl whohave responded to first-line therapy and who are undergoing asct.■ Maintenance therapy with rituximab is recommended for patients with newly diagnosed mcl who have undergoneasct.
