Abstract Abstract 1612 INTRODUCTION: in follicular lymphoma (FL) patients with high tumor burden (as defined by GELF criteria), R-CHOP is the standard upfront immunochemotherapy. Results from the PRIMA study suggest that a positive PET after induction therapy predicts for earlier relapses, even despite maintenance with rituximab (RTX) for two years [Trotman J, 2011]. For patients under 65y, who relapse after R-CHOP+/−RTX maintenance with high tumor burden, R-chemo+autografting is a recommended option. In a retrospective cohort of 43 relapsed FL pts in two French University Hospitals, we explored the role of such a strategy on outcome - in the era of new RTX based modalities - and also evaluated the impact of PET results before autografting. PATIENTS AND METHODS: Patients with relapsed FL after R-CHOP, with at least 1 GELF criteria at relapse (high tumor burden), and who received R-chemo before autografting were eligible. IWC+PETresponse criteria (Cheson 2007) were used, after R-CHOP frontline, and after salvage (before autografting). Patients with Richter transformation at relapse were excluded from this study. OS was calculated from date of salvage to date of death or last follow-up; progression-free survival (PFS) and time to next treatment (TTNT) were calculated from completion of salvage to date of FL relapse or next chemotherapy, respectively. RESULTS: 43 pts (60% males) younger than 65y were identified: they received either FCR-based (2 cycles of FCR, 1 cycle of R-DHAP then stem cell harvest, 2 last cycles of FCR, n=25) or R-DHAP-based (4 cycles of R-DHAP or DHAOx (oxaliplatin replacing cisplatin), and stem cell harvest, n=18). Characteristics at salvage: median age was 54 (range 28–62), with median GELF score of 1 (1–4). Thirty % had progression within 6 mo of R-CHOP (refractory);median PFS was 12mo (range 1–40mo) andmedian TTNT was 15mo. RTX maintenance in 12/43 pts did not significantly increased PFS (15 vs 9 mo, p=0.1). FLIPI1 was low in 39%, Int 36%, high 25% of pts, and FLIPI2 was low in 22%, Int 62.5%, high 15.5% of pts. 1/43 pt had CD20- relapse (who received RTX maintenance), and received FC without RTX. Results: response to FCR/R-DHAP included CR+CRu 68/72%, PR 24/28% respectively, PET evaluation was found negative in 23.5/36% respectively (p=ns). Median stem cell harvest (median 2 leukaphereses) was 4.37 vs 7.8.106 CD34+/kg in FCR vs R-DHAP pts (Mann-Whitney p=0.09), without failure (only one patient required plerixafor). Four patients did not receive the planned autologous transplant (2 failures after FCR (including one Richter transformation), 1 hepatitis before conditioning regimen, 1 withdrawal of consent). Conditioning regimen for the remaining 39 pts was BEAM in 16 (4 FCR+12 R-DHAP), Zevalin-BEAM in 23 pts (9 FCR+14 R-DHAP), including 9 pts who further received RTX maintenance post-autografting. At a median follow up of living pts of 18mo, 9 pts had relapsed, of which 8 needed additional therapy. At time of analysis (June 2011), 37 pts were alive. Causes for death included 1 pancytopenia and infection, 1 Richter syndrome, 1second cancer, 2 complications of allografting (received later on). Late complications were common: pancytopenia or prolonged grade III-IV neutropenia (>3mo) after procedure occurred in 5/43 pts (3 FCR, 2 R-DHAP, without evidence of MDS/AML in these cases), Richter syndrome occurred in 2 patients (1 death), second cancer in 3 pts (1 Hodgkin, 1 womb sarcoma, 1 lung cancer). On an intend-to-treat basis, 41 pts are evaluable. For FCR/R-DHAP pts, 2y PFS was 68/68%, 2y TTNT 80/70%, and 2y OS 73/100%, respectively (logrank p=ns). Two years TTNT tended to be higher in pts receiving Z-BEAM (55 vs 83%), or with PET negativity before autografting (70 vs 85%), both without reaching significance (logrank p=0.1). PET negativity before autografting was the only variable statistically associated with superior OS in our series (logrank p=0.0003). CONCLUSIONS: Our data suggest that PET negativity before consolidative autografting is an achievable and desirable goal in FL salvaged after R-CHOP.

Nonmyeloablative Stem Cell Transplantation

Abstract Nonmyeloablative stem cell transplantation in patients with follicular lymphoma has been designed to exploit the graft-versus-lymphoma immunity. The long-term effectiveness and toxicity of this strategy, however, is unknown. In this prospective study, we analyzed our 8-year experience. Patients received a conditioning regimen of fludarabine (30 mg/m2 daily for 3 days), cyclophosphamide (750 mg/m2 daily for 3 days), and rituximab (375 mg/m2 for 1 day plus 1000 mg/m2 for 3 days). They were then given an infusion of human leukocyte antigen-matched hematopoietic cells from related (n = 45) or unrelated donors (n = 2). Tacrolimus and methotrexate were used for graft-versus-host disease (GVHD) prophylaxis. Forty-seven patients were included. All patients experienced complete remission, with only 2 relapses. With a median follow-up time of 60 months (range, 19-94), the estimated survival and progression-free survival rates were 85% and 83%, respectively. All 18 patients who were tested and had evidence of JH/bcl-2 fusion transcripts in the bone marrow at study entry experienced continuous molecular remission. The incidence of grade 2-IV acute GVHD was 11%. Only 5 patients were still undergoing immunosuppressive therapy at the time of last follow-up. We believe that the described results are a step forward toward developing a curative strategy for recurrent follicular lymphoma.

Abstract The role of an intensified program of autologous stem cell transplantation (ASCT) following a consolidation phase with alemtuzumab (A) in pts with chronic lymphocytic leukemia (B-CLL) who received a fludarabine-based regimen (Fbr) as debulking is still considered questionable. The reported evidence of a prolonged treatment free-survival and survival associated to the absence of minimal residual disease (MRD) in B-CLL pts treated with A doesn’t seem to justify an intensification with ASCT in case of MRD-. We have already reported our experience in B-CLL pts treated with Fbr who after a median period of discontinuation of 16 weeks, received A sc (10 mg x 3/w for six weeks) in order to obtain the maximum response of MRD negative remission. Pts obtaining a successful peripheral blood stem cell harvest (PBSC) were considered eligible for ASCT. After a longer follow-up period we analyze here the outcome of autografted pts. Furthermore results were compared with those of pts treated with the same regimen but excluded from transplant procedure. Overall 48 pts have been considered for the analysis. Twenty-nine pts underwent an ASCT. Mobilization regimen consisted in all but 1 pt of Ara-C (800 mg/ sqm/12h x 3 days) followed by granulocyte colony-stimulating factor (G-CSF) while the last patient received only G-CSF. Reason for exclusion from ASCT procedure in the 19 non transplanted pts was: 9 refusal, 4 progressive disease, 1 evolution to Richter syndrome, 2 priming failure, 3 physician decision. Initially, in the group of non-transplanted pts, 9 (47%) were in stage A, 9 (47%) B, 1 (6%) C; ZAP70 was positive in 4 (21%) cases. Response after consolidation with A was: 7 MRD- CR (37%), 7 MRD+ CR (37%), 1 PRn (5%), 4 PR (21%). As regards the transplanted pts: 9 (31%) were in stage Binet A, 16 (55%) B, 4 (14%) C; ZAP70 was positive in 10 (34%) cases. Disease status after A was as follows: 18 MRD- CR (62%), 6 MRD+ CR (21%), 5 PRn (17%). Median age at transplant was 55 years (range 44–64). In all pts a reassessment of response status was ruled out before transplant to exclude a disease progression. ASCT procedure was performed after a median of 12 mos from last A administration (range 6.5–16.8). One pt who reactivated a virus B hepatitis after consolidation was successfully transplanted after 16.8 mos interval from alemtuzumab. Conditioning regimen consisted of 12 Gy total body irradiation plus cyclophosphamide 120 mg/kg in 21 pts <60 years, and melphalan 180 mg/m2 in 8 pts ≥60 years. Median number of CD34+ cells reinfused was 14x106/kg (range 3.1–41); in 15 cases (52%) the reinfused product was polyclonal for IgH rearrangement. The median time for PMN ≥500/mcL and PLT ≥20,000/mcL recovery was 9 (range 6–10 days) and 10 days (range 3–13 days) respectively. No incidence of grade 3–4 non hematologic toxicity was observed. None of the patients developed CMV reactivation, even in pts who showed a CMV reactivation during A treatment. One patient died (TRM 3.4%) due to a pulmonary fungal infection sustained by Aspergillus terreus. Disease assessment after transplant showed MRD- CR in 25 (86.2%) pts, in the remaining pts 2 MRD+ CR and 1 PRn were detected. In the transplanted population after a median follow-up of 46.3 mos (range 15.2–73.4) from last A administration and 35 mos from ASCT (range 2–59.8 months) 82% of pts are in CR according to NCI WG criteria. After the same follow-up period 20 (69%) pts are still in MRD- CR. Two pts died, one in MRD- CR for a lung cancer and one for fungal infection after transplant, two relapsed, after 45 and 15 mos respectively. In the non-transplanted pts after a median followup of 12 mos (range 1.5–64.2) from A 13 (68%) pts relapsed. Six pts died, 3 for disease progression, 1 for breast cancer, 1 for Richter syndrome and 1 for IMA while in MRD- CR. In conclusion in our experience ASCT following a chemo-immunotherapy confers a long disease free survival at 5 years (82%). Even if the population of non transplanted is not directly comparable, as transplanted pts were selected based on their response and the adequacy of the stem cell harvest, it is remarkable that in those pts the 5 year disease free survival is only of 32%. The in vivo “purging” effect of A given as consolidation facilitated the achievement of an high rate of MRD- PBSC collections. We can speculate that the reduced contamination of the reinfused product translated in sustained molecular remission after transplant. Moreover, this prospective single centre survey showed a low treatmentrelated mortality and absence of secondary MDS.

Abstract Purpose Prior to the introduction of modern induction and maintenance regimens, autologous stem cell transplantation (ASCT) improved outcomes in chemotherapy-sensitive, relapsed follicular lymphoma (FL). We re-evaluated the impact of Rituximab (R) sensitivity on ASCT for relapsed FL in the current Rituximab era. Methods 194 consecutive patients with a confirmed diagnosis of relapsed, grade 1, 2 or 3A FL underwent ASCT at our center from April 1993 to October 2011. They were categorized as R-sensitive, R-refractory, or no R (NoR) if transplanted prior to use of Rituximab. Rituximab refractoriness was defined as failure (at any point in treatment) to achieve at least a PR or documented disease progression within 6 months of receiving the first dose of a full course of single-agent rituximab (³ 4 doses of 375mg/m2 weekly), getting rituximab maintenance (R-maintenance) or completing 2 courses of Rituximab combined with chemotherapy (R-chemotherapy). The statistical significance of differences in event rates was evaluated with the proportional hazards regression model. Two-sided p-values less than 0.05 were considered statistically significant. Kaplan-Meier (K-M) curves were used to estimate the probabilities of overall survival (OS) and progression-free survival (PFS). Cumulative incidence of relapse was calculated in a competing risk data analysis considering non-relapse mortality as a competing event. Results There were 65 rituximab-refractory (RR), 35 rituximab-sensitive (RS) and 94 NoR patients. RS (11%) and RR (12%) patients received R-maintenance. High-risk FL international prognostic index (FLIPI) scores at the time of ASCT was imbalanced between the groups: RS 3%, RR 23% and NoR 26% (P = .009). Baseline characteristics were otherwise comparable between the 3 groups. Median follow-up from ASCT to time of last contact or death was 64 months (range 10-169), 42 months (range 1-157) and 91 months ( range 0.5-231) in the RS, RR and NoR groups, respectively. Univariate analyses showed significantly better OS (P = .003) and PFS (P = .0004) in RS patients with 3-year OS and PFS (Figure 3) of 97% and 85% compared with 63% and 35% in RR and 73.4% and 49% in NoR patients, respectively (Figures 1 & 2). Time to next treatment in relapsing patients was significantly shorter in the RR group compared to the RS and NoR groups. We performed multivariate adjustment for pre-ASCT factors that could affect outcomes i.e. age ≥ 50, FLIPI score ≥ 3, # prior chemotherapy regimens ≥ 3, chemo-resistance, elevated lactate dehydrogenase, prior radiation therapy, bone marrow stem cell source, and remission quotient ≥ 6 (defined as the months from diagnosis to ASCT divided by number of prior therapies). Multivariate adjustment showed OS to be significantly affected only by rituximab sensitivity, with a lower risk of death in RS patients (HR 0.24, P = .01). PFS was also significantly affected by pre-ASCT rituximab sensitivity (HR 0.35, P = .006). Cumulative incidence of relapse was increased in RR patients (HR 2.11, P = .01). The differences in post-ASCT OS, PFS, and relapse rates between the RS and RR patients were maintained independent of transplant conditioning regimen. There were no differences in OS, PFS or relapse whether RR patients were refractory to single-agent rituximab, R-maintenance, or R-chemotherapy. Conclusions Pre-transplant rituximab sensitivity in relapsed FL is a strong independent predictor of post-ASCT outcome. For RR FL patients with limited effective options, nearly half were alive and progression-free at 3 years after ASCT.

Abstract Introduction First-line immunochemotherapy followed by two years of rituximab (R) maintenance is now the standard of care for high-tumor burden follicular lymphoma (FL). In spite of an old controversy regarding the heterogeneous metabolic activity of FL lesions, either interim or final PET-CT after R-CHOP first-line therapy is now recognize to be strongly predictive of outcome. At the time of relapse, R-chemotherapy and autologous stem cell transplantation (ASCT) is a recommended option. Though, some patients will relapse quickly while others achieve long-term remissions. We investigated the prognostic value of PET-CT in patients with high-tumor burden relapsed FL treated with salvage R-chemotherapy followed by ASCT. Patients and Methods Seventy-five patients with relapsed FL referred to three French institutions were retrospectively analyzed. Patients with grade 3b follicular lymphoma or transformed into diffuse large B-cell lymphoma were excluded. Patients received second-line immunochemotherapy according to the local physician’s choice. We classified these salvage treatments into three groups: fludarabine-based regimen (n=29, group 1), cytarabine-based regimen (n=31, group 2), or ifosfamide-based regimen (n=15, group 3). PET-CT scans performed after salvage therapy (before ASCT) were included in the analyses. The local investigator’s interpretation of the imaging physician’s scan report defined a positive or negative PET. Results Median age was 56 years and 60% were men. Sixty eight patients received ASCT. Among this whole high-risk study population, 87% relapsed before 36 months after R-CHOP and 42% relapsed within 6 months and were therefore considered as R-CHOP refractory, with a median progression free survival (PFS) after R-CHOP first-line therapy of 15 months. Only 21% of the patients received R maintenance after R-CHOP. PET-CT scans after salvage therapy (before ASCT) were considered negative in 57%/76%/47% among the 3 groups respectively (p=0.06). Median stem cell harvest was higher in group 3-ifosfamide-based (8.3.106) than in both fludarabine and cytarabine-based regimens (4.47 and 4.8.106 respectively, Mann-Whitney p=0.15). Conditioning regimen was BEAM (37%) or Zevalin-BEAM (56%). Thirteen patients received R maintenance after ASCT. At a median follow-up of 28 months, 26/75 patients relapsed and 62 are alive. At 2 years, median PFS was 63.8%/66%/53.5% and median overall survival (OS) 68%/94%/92% among the 3 groups, respectively. PFS was only correlated to PET-CT results (p=0.0006). OS was correlated to group of therapy (2-3 versus 1), FLIPI score at relapse and PET-CT negativity. The latter was the strongest OS predictor on a multivariate analysis (p<0.01). On the other hand, age, gender, conditioning regimen, and PFS after R-CHOP (<36 months or even <12 months) were not linked to shorter PFS/OS. We observed 12% of second non-hematologic cancer. Conclusion PET-CT scan negativity after salvage treatment is the most important favourable factor for relapsed/refractory FL patients who receive ASCT.

Abstract BACKGROUND: The outcome of patients with advanced stage Follicular Lymphoma (FL) has improved over the last decade, with the use of monoclonal antibodies (mAbs). The watch and wait approach (WW) in FL with low tumor burden was assumed when treatment options were limited and less effective than nowadays. In FL patients with indolent disease characterized by multiple relapses evolution, the therapeutic strategy should take into consideration the quality and duration of response and the impact on overall survival (OS) versus the risk of long-term toxicity. AIMS: Evaluation of the impact of WW approach compared with chemotherapy (CT) in time to next treatment (TNT), progression-free survival (PFS) and OS. METHODS: Retrospective study of 213 patients with FL, followed in a cancer care center between 2000-2012. Of these, 79 asymptomatic patients at diagnosis, with Ann Arbor stage III-IV were included and divided in 2 subgroups: 58 patients received the first-line treatment and 21 remained in surveillance. Tumor burden defined according to criteria of the Groupe d'Etude des Lymphomes Folliculaires (GELF). Survival analysis using the Kaplan-Meier method. Type of response defined according to NCCN criteria. RESULTS: Median follow-up of 48 months (12-147). 41 of the 58 patients submitted to 1st line treatment [median age 57 years (38-72), 36.2% male], underwent CT regimen containing Rituximab. The majority of these patients presented with follicular pattern and histological grade 1/2 (89.7%), 34.5% had FLIPI ≥ 3 and 50 % high tumor burden (GELF), 15.5% bulky mass, 53.4% had > 4 nodal areas involved and 6.9% > 1 extranodal area involved. 52 of the treated patients (89.7%) achieved CR and in 4 progression occurred (6.9%). 50 patients (86.2%) were alive without evidence of disease at the end of study (86.2%). In the group of patients undergoing surveillance, 11 suffered disease progression (52.4%), of which 10 (47.6%) stayed alive without evidence of disease. The TNT was higher in patients undergoing 1st CT regimen, compared to patients on WW (median 1480.5 vs. 765 months, p <0.001) with significant impact on PFS (p <0.001) but not on OS. Analyzing the treated subgroup, the addition of immunotherapy resulted in better TNT and PFS compared to WW (p <0.001), without affecting the OS. In univariate Cox regression analysis, the number of areas and extranodal tumor burden (GELF) were independent predictors of PFS and TNT (p <0.05). CONCLUSION: In asymptomatic patients with FL stage III-IV and high tumor burden, the CT especially when combined with immunotherapy, showed significant improvement on TNT and PFS compared to a WW approach, with no impact on OS. Despite a small sample group with retrospective data, our results are in agreement with the published literature. Disclosures No relevant conflicts of interest to declare.

Abstract Introduction Allogenic hematopoietic stem cell transplantation (Allo-HSCT) is a curative treatment for patients with myelodysplasia (MDS). However, because of age, MDS patients represent a challenging population for such an intensive treatment. Additionally, the low rate of HLA-identical donor has represented a major limitation in this strategy. Recently, reduced-intensity conditioning (RIC) regimens have made feasible Allo-HSCT in the elderly, although relapse rate might be increased. Additionally, the development of HSCT using alternative donors overcomes HLA-compatibility limitations. Graft-versus-host disease (GVHD) is a major post-transplant event, graft-versus-leukemia effect being counterbalanced by toxicity and impaired quality of life. The aim of this retrospective study was to report outcome of patients with MDS who underwent Allo-HSCT and to study the impact of GVHD. Methods Between 2003 and 2014, 100 consecutive patients presenting with MDS, or MDS-secondary AML, underwent Allo-HSCT in our institution. At diagnosis, 58 patients had ≥ 2 cytopenias. IPPS was low/intermediate-1 in 46% and intermediate-2/high in 54%, R-IPSS was very low/low in 25%, intermediate in 20% and high/very high in 55%. Cytogenetics, according to Disease Risk Index (DRI), was intermediate in 79% and adverse in 21%. Secondary MDS represented 27% of our cohort. Before Allo-HSCT, 42% received 5-Azacytidine, 27% intensive chemotherapy and 9% were transplanted upfront. At the time of Allo-HSCT, the median recipient age was 61 (19-71) years. Median time between diagnosis and Allo-HSCT was 12 months (1-131). After excluding patients transplanted upfront, 31 patients still had ≥5% blasts after treatment. Donors were HLA-matched in 70% (41% related, 29% unrelated), 30% were not HLA-matched (10% unrelated, 7% cord blood, 13% T-repleted haplo-HSCT). Stem cell source was peripheral blood stem cells in 90%. Twelve percent of patients received non-myeloablative (NMA) conditioning regimen, 75% RIC and 13% reduced-toxicity conditioning (RTC) regimens. Post-graft immunosuppression consisted in cyclosporine A (CSA) in 58%, CSA-Mycophenolate Mofetil (MMF) in 15%, CSA-Methotrexate in 14% and CSA-MMF-Cyclophosphamide for haplo-HSCT (13%). Results Median follow-up was 37 months (3-197). The incidence of 3-4 acute GVHD at day 100 was 7% (95% CI = 2-12). The incidence of severe chronic GVHD at 3 years was 19% (95% CI = 11-27). One and 3-year non-relapse mortality (NRM) were 23 and 29% respectively. The cumulative incidence of relapse (CIR) at 1 year and 3 years 24% and 33% respectively. One and 3-year progression-free survival (PFS) were 52% (95% CI = 43-63) and 37% (95% CI = 28-49). One and 3-year overall survival (OS) were 60% (95% CI = 51-71) and 48% (95% CI = 39-60). At one year, 51 patients were alive and disease-free, including 61% (n=31) without immunosuppression. At the end of follow-up, 39 patients were alive and disease-free, including 85% (n=33) without immunosuppression and 77% (n=30) GVHD-free. Time-dependent analysis of GVHD impact (Table 1), adjusted on age, donor-type, DRI and conditioning regimen, revealed that acute GVHD strongly impacts on OS (HR 3.8, 95% IC = 2-7, p<0.01), PFS (HR 3.1, 95% CI = 1.7-5.6, p<0.01) and NRM (HR 12, 95% CI = 5.2-28, p<0.01). Chronic GVHD was statistically significant on CIR (HR 0.16, 95% CI = 0.04-0.7, p=0.02) and NRM (HR 2.8, 95% CI = 1-8, p=0.05). Pre-transplant disease characteristics did not have any impact by univariate analysis. Multivariate analysis did not find any impact of age, donor type, DRI and conditioning regimen in terms of OS, PFS, NRM and CIR. Conclusion Our results suggest that GVHD highly influences outcome, regardless of MDS and Allo-HSCT characteristics. It should be quoted that a significant number of patients are alive, long-term survivors, disease-free and GVHD-free suggesting good quality of life.

The Impact

Complex karyotype (CK) at chronic lymphocytic leukemia (CLL) diagnosis is a negative biomarker of adverse outcome. Since the impact of CK and its subtypes, namely type-2 CK (CK with major structural abnormalities) or high-CK (CK with C5 chromosome abnormalities), on the risk of developing Richter syndrome (RS) is unknown, we carried out a multicenter reallife retrospective study to test its prognostic impact. Among 540 CLL patients, 107 harbored a CK at CLL diagnosis, 78 were classified as CK2 and 52 as high-CK. Twenty-eight patients developed RS during a median follow-up of 6.7 years. At the time of CLL diagnosis, CK2 and high-CK were more common and predicted the highest risk of RS transformation, together with advanced Binet stage, unmutated (U)-IGHV, 11q-, TP53 abnormalities. We integrated these variables into a hierarchical model: high-CK and/or CK2 patients showed a 10-year time to RS (TTRS) of 31%; U-IGHV/11q-/TP53 abnormalities/Binet stage B-C patients had a 10-year TTRS of 12%; while mutated (M)-IGHV without CK and TP53 disruption a 10-year TTRS of 3% (p<0.0001). We herein demonstrated that CK landscape at CLL diagnosis allows to refine the risk of RS transformation and we recapitulated clinico-biological variables into a prognostic model.

Abstract Abstract 2031 Background: The role of High-Dose Therapy (HDT) and Autologous Stem Cell Transplantation (ASCT) as salvage therapy in relapsed Follicular Lymphoma (FL) has been questioned since the introduction of Rituximab in the treatment of FL. Our objectives were to evaluate the long-term event-free survival (EFS) and overall survival (OS) rates of patients with relapsed or refractory FL who received HDT and ASCT as salvage therapy. Our secondary objective was to compare EFS of patients who received ASCT before and after 2002 (the year Rituximab become fully available for use in our country). Patients and Methods: We conducted a retrospective analysis of 123 consecutive patients with relapsed or refractory FL who had received HDT and ASCT as salvage therapy in five Argentinean transplant centers from 1992 to 2012. Results: One hundred twenty tree patients (median age: 48 years, range: 23–72) were transplanted, 71 (58%) male, 37/106 (35%) had FL Grade 1, 47/106 (44%) FL Grade 2 and 22/106 (21%) FL Grade 3; 75/102 (73%) of patients have a stage III-IV disease at the moment of diagnosis and 27/102 (26%) have a disease stage I-II. Before transplantation 78/121 (64%) patients were in Complete Response (CR), 42/121 (35%) were in Partial Response (PR) and one patient had a Progressive Disease. Fifty four patients (44%) were transplanted before 2002 (before Rituximab era in our country). The conditioning regimens used were CBV 94 (76%), BEAM/BEAC 27 (22%), others regimens two patients; only one patient received TBI containing conditioning regimen and was excluded for conditioning regimen PFS curve calculation. The median time from FL diagnosis to ASCT was 29 (range 1–300) months. The transplant related mortality (until day 90 after ASCT) was 5%. With a median follow-up of 52 (range 0–247)months, the median EFS was reached at 44 months and a plateau on the EFS curve was evident starting at 6 years after ASCT. The 10 years-projected EFS was 36% (Figure 1). The median OS was not reached during follow-up. Median EFS for patients who were transplanted before 2002 (before Rituximab era) and for those who were transplanted after 2002 was 41 months and 47 months respectively [HR 1.01; IC (0.61–1.65); p=0.97]. EFS rates difference was not statically significant between patients who previously transplantation have achieved a CR or a PR, median EFS 47 and 68 months respectively [HR 0,94; IC (0,56–1,58); p= 0,82]. There was no difference in EFS rates between patients who received CBV as conditioning regimen and patients who received BEAM/BEAC, median EFS 57.6 months and 16.3 months respectively [HR 0.67; IC (0,34–1.35); p=0.2]. The median EFS rate for patients with FL Grade 1, FL Grade 2 and FL grade 3 were 58, 44 and 16 months respectively, P for trend = 0.78. Seven cases (5,7%) of secondary malignancies were detected, six cases (6/94; 6,4%) in patients who received CBV as conditioning regimen (urotelial carcinoma, pancreas carcinoma, lynfoprolipherative disorders, non-melanoma skin malignancies and prostate carcinoma) and one case (1/27; 3,7%) in patients who received BEAM (urotelial carcinoma), p=0,85; there were no reports of secondary myelodysplastic syndromes/acute myeloid leukemia. Conclusion: In this study, 50% of the patients analyzed were free from progression after 44 months of ASCT and approximately a 30% of patients achieve long term remission. According to this, patients with relapsed or refractory FL can achieve long-term EFS with HDT followed by ASCT. Disclosures: No relevant conflicts of interest to declare.

Abstract Background Anemia has been a known prognostic factor in metastatic hormone-sensitive prostate cancer (mHSPC). We therefore examined the effect of anemia on the efficacy of upfront abiraterone acetate (ABI) in patients with mHSPC. Methods We retrospectively evaluated 66 mHSPC patients with high tumor burden who received upfront ABI between 2018 and 2020 (upfront ABI group). We divided these patients into two groups: the anemia-ABI group (hemoglobin < 13.0 g/dL, n = 20) and the non-anemia-ABI group (n = 46). The primary objective was to examine the impact of anemia on the progression-free survival (PFS; clinical progression or PC death before development of castration resistant PC) of patients in the upfront ABI group. Secondary objectives included an evaluation of the prognostic significance of upfront ABI and a comparison with a historical cohort (131 mHSPC patients with high tumor burden who received androgen deprivation therapy (ADT/complete androgen blockade [CAB] group) between 2014 and 2019). Results We found that the anemia-ABI group had a significantly shorter PFS than the non-anemia-ABI group. A multivariate Cox regression analysis showed that anemia was an independent prognostic factor of PFS in the upfront ABI group (hazard ratio, 4.66; P = 0.014). Patients in the non-anemia-ABI group were determined to have a significantly longer PFS than those in the non-anemia-ADT/CAB group (n = 68) (P < 0.001). However, no significant difference was observed in the PFS between patients in the anemia-ABI and the anemia-ADT/CAB groups (n = 63). Multivariate analyses showed that upfront ABI could significantly prolong the PFS of patients without anemia (hazard ratio, 0.17; P < 0.001), whereas ABI did not prolong the PFS of patients with anemia. Conclusion Pretreatment anemia was a prognostic factor among mHSPC patients who received upfront ABI. Although the upfront ABI significantly improved the PFS of mHSPC patients without anemia, its efficacy in patients with anemia might be limited.

Abstract Background Concomitant tricuspid regurgitation (TR) is a common finding in mitral regurgitation (MR). Transcatheter repair (TMVR) is a favorable treatment option in patients at elevated surgical risk. To date, evidence on long-term prognosis and the prognostic impact of TR after TMVR is limited. Methods Long-term survival data of patients undergoing isolated edge-to-edge repair from June 2010 to March 2018 (combinations with other forms of TMVR or tricuspid valve therapy excluded) were analyzed in a retrospective monocentric study. TR severity was categorized and the impact of TR on survival was analysed. Results Overall, 606 patients [46.5% female, 56.4% functional MR (FMR)] were enrolled in this study. TR at baseline was categorized severe/medium/mild/no or trace in 23.2/34.3/36.3/6.3% of the cases. At 30-day follow-up, improvement of at least one TR-grade was documented in 34.9%. Severe TR at baseline was identified as predictor of 1-year survival [65.2% vs. 77.0%, p = 0.030; HR for death 1.68 (95% CI 1.12–2.54), p = 0.013] and in FMR-patients also regarding long-term prognosis [adjusted HR for long-term mortality 1.57 (95% CI 1.00–2.45), p = 0.049]. Missing post-interventional reduction of TR severity was predictive for poor prognosis, especially in the FMR-subgroup [1-year survival: 92.9% vs. 78.3%, p = 0.025; HR for death at 1-year follow-up 3.31 (95% CI 1.15–9.58), p = 0.027]. While BNP levels decreased in both subgroups, TR reduction was associated with improved symptomatic benefit (NYHA-class-reduction 78.6 vs. 65.9%, p = 0.021). Conclusion In this large study, both, severe TR at baseline as well as missing secondary reduction were predictive for impaired long-term prognosis, especially in patients with FMR etiology. TR reduction was associated with increased symptomatic benefit. Graphic abstract
