Abstract Introduction It is postulated that the improvement in the overall treatment outcome in adult Ph-negative ALL came from the implementation of more aggressive pediatric-like protocols and higher portion of allogeneic HSCT. Here we report the results of the adult (15-55 yy) Ph-negative ALL protocol based on the opposite approaches: less intensive but non-interruptive treatment with low numbers of allo-HSCT. The study is registered on the ClinicalTrials.gov public site; NCT01193933. Patients and Methods The ALL-2009 is based on: (1) the replacement of prednisolone (Pdn) 60 mg/m2 with dexamethazone (Dexa) 10 mg/m2 if blast cells are >25% in b/m after prephase (7d); (2) de-intensified but non-interruptive 5 months induction/consolidation treatment (5 wks prd/dexa with 3 instead of 4 dauno/vncr pulses, 4 weeks of 6MP with 5 L-asp, 2 instead of 4 ARA-C blocks, 1 instead of 2 Cph injections during induction; induction-like 3 consolidations for 3wks, 2wks, 4wks-continuously without intervals), followed by (3) 2 late (at 6 mo) intensifications- with 1 day HD MTX and with 1 d HD ARA-C, both with L-asp and 3 ds dexa and (4) 2-yrs continuous 6MP/MTX maintenance with doses modification according to myelosuppression with monthly 3-days dexa/vncr/L-asp pulses (∑ L-asp = 590.000 IU/m2). The protocol was identical for all risk groups. Allo-HSCT was indicated only for extremely high-risk BCP-ALL (t(4;11),L>100). No central MRD monitoring was performed. Since Apr 2009 till June 2015 20 centers had recruited 168 BCP-Ph-negative ALL pts with a median age 28 years (15-54), 84f/84 m. Full cytogenetics was available in 67,3% (n=113), 43,4% of them (n=49) had normal karyotype (NK), 10% (n=9%) had no mitosis, 47,6% (n=54) - different abnormalities (hypoploid-1, hyperploid-12, t(11q23)/MLL-8, del11q23-2, t(1;19)-2, t(12;21)-1;others-28). 26,7% of pts (n=45) were in the standard risk (SR) group (WBC <30, EGIL BII-III, LDH < 2N; no late CR; t(4;11)-negative), 56,5% (n=95) - in the high risk (HR) group (WBC >30; EGIL BI, LDH > 2N; late CR; t(4;11)-positive), 28 patients (n=16,8%) were not qualified by the risk. The analysis was performed in June 2015. 158 pts were available for analysis. Results CR rate in 158 available for analysis pts was 87,7% (n=139), induction death occurred in 9,1% (n=14), resistance was registered in 3,2% (n=5). The majority of CR pts (87,8%) achieved it after prephase (12,2%, n=17) and the 1st phase of induction (75,6%, n=105). Late responders constituted 12,2% (n=17). Allogeneic BMT was performed only in 9 of 144 patients who survived induction (6,2%). Totally 31 pts (22,3%) had relapsed. At 60 mo OS for the whole group constituted - 50%, DFS - 51.3%. In a univariate analysis among various risk factors (age <> 30y, initial risk group, WBC, LDH, immunophenotype, late response >35d, PRD resistance) age (>30 y) became statistically significant for OS, DFS and relapse probability (RP) (pic.1), abnormal karyotype - for DFS (30% vs 68%, p=0,04) and RP (42% vs 19%, p= 0,04). In a multivariate analysis no common risk factors were significant. Conclusions Our data demonstrate that the proposed treatment approach is rather effective. We believe that constant non-interruptive treatment without intensive highly myelosuppressive consolidation courses and high portion of allogeneic HSCT may become an alternative and reproducible approach in adult Ph-negative ALL, though we have to stress that it should be very strict compliance of the pts to the protocol. All pts, mostly from the region hospitals who refused prolonged and constant treatment (~5%), relapsed. Figure 1. Figure 1. Disclosures No relevant conflicts of interest to declare.

Abstract Abstract 3080 As compared to single-unit CBT, DCBT may improve engraftment and protect against relapse. Therefore, we have adopted DCBT for both children and adults with acute leukemia, myelodysplasia (MDS), and myeloproliferative diseases (MPD). However, determinants of disease-free survival (DFS) have yet to be fully established. Furthermore, whether DFS after DCBT is comparable in patients of European and non-European ancestry is of special interest. Therefore, we analyzed the DFS of 75 DCBT recipients with acute leukemia in morphologic remission or aplasia (n = 69), and MDS/MPD with ≤ 5% blasts (n = 6) transplanted from 10/2005-4/2011. Nearly all patients had high-risk disease. Children 0–15 years (n = 23) had the following characteristics: median age 9 years (range 0.9–15); median weight 37 kg (range 7–72); 30% European; and 26% CMV sero-positive. Diagnoses were 43% AML (or biphenotypic), 52% ALL, and 4% MDS/MPD, and all received high-dose conditioning. The children received grafts with a median infused TNC × 107/kg of 3.3 (larger unit) and 2.6 (smaller unit), and 2% of units were 6/6 HLA-A, -B antigen, -DRB1 allele matched, 63% 5/6, and 35% 4/6. Adults ≥ 16 years (n = 52) had the following characteristics: median age 41 years (range 16–69); median weight 69 kg (range 47–105); 48% European; 69% CMV sero-positive; and diagnoses were 63% AML (or biphenotypic), 27% ALL, and 10% MDS/MPD. Fifty percent received high-dose and 50% reduced intensity conditioning. Their units had a median infused TNC/kg of 2.7 and 1.9, and 3% were 6/6 HLA-matched, 47% 5/6, and 50% 4/6. All patients (pediatric and adult) received calcineurin-inhibitor/ mycophenolate mofetil immunosuppression, and none received anti-thymocyte globulin. Sustained donor neutrophil engraftment was seen in 91% of children and 94% of adults at medians of 20 and 26 days, respectively. The incidence of grade II-IV acute GVHD by day 180 was 44% in children and 58% in adults. Day 100 transplant-related mortality (TRM) was 9% in children and 19% in adults. The 2-year relapse incidence was 9% in children and 6% in adults. With a median follow-up of survivors of 26 months (range 4–70), 2-year Kaplan-Meier estimate of DFS was 78% in children and 64% in adults (Figure). Differences in survival by age did not reach significance. Univariate analysis of variables potentially influencing 2-year DFS (with log rank estimates of significance) in all patients is shown in the Table. There were no differences in 2-year DFS according to ancestry, remission status, and conditioning intensity. There was also no difference in 2-year DFS according to engrafting unit-recipient HLA-match (4-6/6 or 10 allele), or engrafting unit infused TNC dose/kg. However, patients who were CMV seronegative had a higher 2-year DFS (85% vs 55%, p = 0.018). Multivariate analysis revealed recipient CMV serostatus was a predictor of DFS independent of patient age, and its effect was mediated by an influence on TRM. We have previously shown that DCBT extends transplant access to minority patients. We now demonstrate that DCBT can achieve high and comparable DFS in both European and non-European pediatric and adult patients with acute leukemia and MDS/MPD. While these are very encouraging results further investigation in racial/ethnic sub-groups is needed. Nonetheless, our findings support DCBT as an immediate alternative therapy for high-risk acute leukemia in patients without suitable unrelated volunteer donors, especially given the very low incidence of relapse.

Abstract Introduction: Cytomegalovirus (CMV) is a major infectious complication following allogeneic hematopoietic stem cell transplantation (HSCT). Risk of CMV infection varies between patients and individualized strategies for monitoring and therapy for CMV are needed. In this study, we attempted to establish a clinical score based on patient and transplant characteristics in order to predict the probability for early CMV viremia (CMV-V) within the first 100 days after HSCT. Methods: A total of 548 patients were evaluated after receiving HSCT between 2005 and 2012 at Princess Margaret Cancer Centre. CMV sero-negative recipients with CMV sero-negative donors (R-D-) were excluded. CMV-V was diagnosed in peripheral blood samples obtained on two occasions either by PCR (>200 IU/ml) or antigenemia testing (>2 positive cells/100000). A total of 378 patients were included into the study. Uni- and multivariable analyses were performed to identify risk factors for CMV-V. A weighted score was assigned to each factor based on the odds ratios determined by the multivariable analysis. A total score was calculated for each patient and used for assignment into one of 4 risk categories, the low risk (score 0-1), the intermediate (score 2-3), the high (score 4-5) and the very high (score 6-8). Median age for all patients was 51 years (range 17-71) and 173 (46%) were female. Matched related donors were used for two hundred fifteen patients (57%). Two hundred forty-three patients (64%) were transplanted for myeloid and 108 (29%) for lymphoid malignancies. One hundred thirteen patients (30%) were CMV sero-positive with a negative donor (R+D-) while 191 (51%) were recipient and donor CMV sero-positivity (R+D+). Graft versus host disease (GVHD) prophylaxis included CSA/MMF (n=200, 52%), and CSA/MTX (n=178, 48%). Myeloablative conditioning regimens were administered to 220 patients (58%), 158 patients (42%) were treated with a reduced intensity regimen. Three hundred-thirty seven patients (89%) received peripheral blood stem cells as a stem cell source. In vivo T cell depletion (TCD) with alemtuzumab was used in 138 (37%). Results: CMV-V occurred in 246 (64%) patients by day 100 post HSCT. The impact of patient and HSCT characteristics on the risk of CMV-V was assessed by multivariable analysis. The significant factors were CMV sero-status R+D- and R+D+, TCD, GVHD prophylaxis with MMF administration of myeloablative preparative regimens (Table 1). Table 1. Multivariate analysis for risk factors of CMV infection following allogeneic HSCT Table 1. Multivariate analysis for risk factors of CMV infection following allogeneic HSCT CMV-V rates on the 4 new risk categories amounted to 93% in the very high-risk, 78% in high-risk, 41% in intermediate-risk and 11% in low-risk group (Fig 1). The risk score was also predictive for the occurrence of multiple CMV-V reactivations with rates of 71%, 45%, 19% and 4% for the very high, high, intermediate and low-risk groups, respectively. The overall survival (OS) rate at 2 years was 33%(n=56) in the very high-risk group compared to 50% in other-risk groups (n=147) (P=0.01) (Fig 2). Non-relapse mortality (NRM) was 53% in the very high-risk versus 33% in other-risk groups (P<0.001). However, there was no difference on cumulative incidence of relapse between the groups (P=0.3). The cumulative incidence of grades 1-4 acute GVHD, grades 2-4, grades 3-4 at day 120 and overall chronic GVHD at 2 years was 68%, 47%, 25% and 39% in very high-risk group versus 65%, 52%, 21% and 52% in other-risk groups, suggesting slightly lower incidence of chronic GVHD in very high-risk vs other-risk groups. Conclusion: We present a new clinical scoring system to stratify the risk of early CMV viremia after allogeneic HSCT based on patients and HSCT characteristics. Identifying the risk for each patient would facilitate decision making with respect to strategies including CMV prophylaxis, pre-emptive treatment or inclusion into clinical trials, as well directing the CMV monitoring policy post-transplant. In addition, the risk score was associated with higher risk of overall mortality and NRM in the very high-risk versus other-risk groups. Figure 1 Figure 1. Figure 2 Figure 2.

Abstract Abstract 2244 Background: Patients (pts) with MM are at increased risk for VTE due to various risk factors related to the host, disease, and treatment. Immunomodulatory drugs (IMiDs) such as thalidomide and lenalidomide have further increased the risk of VTE. Several studies have shown the VTE risk can be reduced with the use of low molecular weight heparin (LMWH) or aspirin thromboprophylaxis. Based on these findings, VTE thromboprophylaxis has been recommended in pts receiving IMiDs + Dexamethasone (Dex), but the impact of these guidelines on patient outcomes in clinical practice is unclear. The objective of this observational study was to evaluate the incidence, timing and risk factors of VTE and the impact of different types of thromboprophylaxis on the incidence of VTE. Methods: This was a retrospective cohort study, and included all MM pts newly referred to the M.D. Anderson Cancer Center in 2006. Medical records of these pts were reviewed for the type and site of VTE, the incidence and timing of VTE during the five-year period from the referral date, and the risk factors, including pt demographics, co-morbidities, baseline laboratory values, types of MM and treatment, and types of thromboprophylaxis. Univariate and multivariate proportional hazard models were fitted to find the independent risk factors predictive of VTE. The stepwise selection method was employed to build a multivariate model using variables with p<0.15 in univariate analysis. Results: The cumulative incidence of VTE was 24% (38/159 pts) during the 5-year follow up period. Of the 38 pts with VTE, 25 (66%) had deep vein thrombosis (DVT), 11 (29%) had pulmonary embolus (PE), and 2 had concurrent DVT and PE. Most of the pts (32/38, 84%) had VTE within 1 year from the referral date. The incidence of recurrent VTE among these pts was 27.5% (11/38 pts), for a total of 52 episodes. Since the majority of VTEs and recurrences were within one year, we examined the risk factors for VTE during this period. Treatment with IMiDs + Dex and thromboprophylaxis with LMWH or Coumadin were independent predictive factors as shown below. The incidence of VTE was highest in pts exposed to IMiDs + Dex (30/38 pts), even after discontinuation of treatment, with most episodes (17/30) occurring during the preparation (7/30) or within 30 days (10/30) following hematopoietic stem cell transplantation (HSCT), when most (16/17) pts were not receiving anti-coagulants. Conclusions: These findings suggest that patients treated with IMiDs + Dex are at high risk for VTE, even after discontinuation of this treatment, especially, during and after the HSCT period. Future studies are needed to investigate VTE prevention strategies for this high-risk pt population. Disclosures: No relevant conflicts of interest to declare.

Abstract Background: Second-line salvage chemotherapy(CT) followed by high-dose (HD) CT and autologous stem cells reinfusion (ASCT) is standard treatment forR/R HL patients, although long-term cure can be achieved in only half of them, depending on risk factors. Chemosensitivity to salvage CT before ASCT, mainly represented by a negative PET scan, is highly predictive of a favorable outcome. The availability of new markers of prognosis, like the measurement of the serum chemokineTARC, could help identifying those patients who may require further treatment, i.e. new drugs like Brentuximab Vedotin or Nivolumab or Pembrolizumab, before ASCT, in order to achieve a durable remission.Therefore we planned to prospectively evaluate the prognostic role of serum TARC levels collected at different time points in cHL R/R patients. Methods: Serum TARC levels were measured by commercially available ELISA test kits (R & D Systems, Minneapolis, USA) in 41 patients treated with IGEV (ifosfamide, gemcitabine, vinorelbine, prednisone) salvage CT, followed by myeloablative B(F)EAM (carmustine, (fotemustine), etoposide, cytosine arabinoside, melphalan) + ASCT at Istituto Nazionale Tumori of Milan, Italy, from January 2007 to December 2013. The 99th centile of TARC distribution in a group of 156 independent healthy subjects corresponding to 800 pg/mL, was considered as cut-off value discriminating between normal and abnormal TARC values. TARC evaluation was performed before starting salvage CT(T0), after the first IGEV cycle (T1) and before ASCT (T-preASCT). The Wilcoxon Mann Whitney test was used to analyze TARC as a function of patient and disease characteristics and PET results. Kaplan-Meyer curves and log-rank test were used to assess differences in PFS according to TARC levels. Cox model was used for multivariate analysis. Results: Main patient characteristics at relapse/progression were as follows: males/females: 19/22, median age: 31 years (range,19-69), B symptoms: 34%, bulky disease: 27%, stage III/IV: 39%, extra nodal involvement: 34%, refractory vs relapsed < 12 months vs relapsed ≥ 12 months: 49% vs 34% vs 17%. Median (IQ range) T0, T1 and T-preASCT were: 1856 (8801-9983) pg/mL, 1148 (544-2532) pg/mL and 829 (454-1725) pg/mL, respectively. Patients with bulky disease had higher median T0 than their counterpart (3241 vs 1462 pg/mL; p=.016). Median T-preASCT was significantly higher in patients with refractory disease compared to relapse < or ≥ 12 months (1100 vs 595, vs 548 pg/mL, p=.027). A positive PET was recorded in 57.5% of patients after 2 IGEV cycles and in 32% before ASCT. Forty-one percent of patients needed ≥ 2 salvage CT before ASCT and 63% had ≥ 2 risk factors. At each time point, median TARC values were significantly higher in PET-2 positive patients compared to their counterpart (T0: 3238 vs 1310; T1: 1866 vs 624; T-preASCT: 908 vs 544; pg/mL). Median (IQ range)T-preASCT levels were significantly higher in patients with a positive PET before ASCT:1091 (596-10578) pg/mL compared to those with a negative one: 651 (447-964) pg/mL. After a median follow-up of 65 months, 5-year PFS and OS (95% CI) were 70 (57-88)% and 84 (72-98)%, respectively. In univariate analysis T-preASCT > 2000 pg/mL, PET-2, PET-preASCT, ≥ 2 risk factors and ≥ 2 salvage CT lines significantly affected PFS. In multivariate analysis only T-preASCT > 2000 pg/mL was significantly associated with a poor PFS (HR 6.65, CI95% 1.12-39.35, p=0.036) as shown in Figure 1. Conclusions: Results of this single institution prospective study suggest that a cheap and easy to perform test, like serum TARC levels measurement before ASCT, may help to ameliorate the identification of those patients at risk of failing ASCT, for whom anticipated use of new active drugs, like anti-CD30 immunoconjugates and/or anti-PD1 blockers, should be explored, in order to improve the cure rate of ASCT.

Abstract In 2003 the German Multicenter ALL Study Group (GMALL) initiated the trial GMALL 07/2003. Major aims were improvement of outcome by shortened, intensified induction, intensified consolidation, risk adapted and extended SCT indication and minimal residual disease (MRD) based treatment stratification. 8drug-induction was followed by uniform 1st consolidation based on HDARAC and HDMTX. Further treatment was stratified according to the following risk factors (RF): WBC > 30.000 in B-prec. ALL, late CR (>3wks), proB-, earlyT and mature T-ALL, Ph/BCR-ABL and t(4;11)/ALL1-AF4. The risk groups were defined as follows: standard risk (SR, no RF), high risk (HR,>= 1RF) and very high risk (VHR,Ph/BCR-ABL). HR and VHR pts were scheduled for SCT in CR1 with the following priorities: allo sibling, allo matched unrelated and autologous. VHR pts mostly received Imatinib according to different schedules. SR pts received 5 consolidation cycles (HDMTX/ASPx3, VP16/ARAC, CYCLO/ARAC) and reinduction. SR pts with high MRD after consolidation I were allocated to SCT. In the remaining SR pts decision on maintenance therapy was based on MRD. Between 04/03-12/06 713 evaluable (15–55 yrs) pts were included. The median age was 34 yrs. The CR rate after induction was 89% with 5% early death and 6% failure. 50%, 33% and 17% were allocated to SR (N=353), HR (N=235) and VHR (N=117) with similar CR rates of 92%, 88% and 85%. CR rate was not different in pts < vs > 35 yrs (90% vs 89%). 5 year overall survival (OS) was 54% and survival of CR (S-CR) pts was 59%. HR and VHR pts obtained 55% and 49% S-CR at 3 yrs resp. HR subgroups showed different S-CR for early T (58%), mature T (70%), pro B (66%) and other B-lineage ALL (37%). 68% and 71% of HR and VHR pts received SCT in CR1 as scheduled which thus contributed substantially to improved outcome. In SR- ALL S-CR was 69% (68% c/preB, 66% thymicT). The CCR probability was 52% at 3 yrs. CNS prophylaxis was very effective since only 2% of the CR pts had CNS involvement at relapse. Univariate analysis confirmed a significant prognostic impact of immunphenotype, WBC in B-lin ALL, time to CR and Ph/BCR-ABL. WBC was no prognostic factor in T-lin-ALL. Age was highly significant for survival with 64% survival < 35 yrs vs 48% above 35 yrs. In adolescents below 25 years the most favourable survival of 67% was achieved. In standard risk pts below 35 yrs the survival was 73% without SCT in CR1. Overall the study yielded improved CR rates (89%) and survival (54%). Risk adapted SCT indication was feasible (realised in 70% of HR/VHR pts) and lead to improved survival particularly in early/mature T-ALL and pro B-ALL. In standard risk (SR) the survival is favourable, even above 70% in young pts; however, the relapse rate is still high. Further intensification of therapy during the first year seems required. By definition of new risk factors additional SR patients could be allocated to SCT in CR1. There is however no intention to transfer all SR patients to SCT. Future improvement will be attempted by further inclusion of subtype specific and targeted therapies.

Abstract Abstract 1969 Background: High-risk MM remains a very difficult clinical challenge despite advances in therapy for the majority of patients who have benefited from the use of high-dose therapies and novel agents. Recognizing that MM from the outset represents a genomically highly complex malignancy with even further accelerated acquisition of mutations with every further relapse, we have tried to develop multi-agent combinations employing drugs with efficacy in other high-grade tumors such as large cell lymphomas and incorporated novel agents as well. Patients and Methods: Eighty-four patients with AHRMM were given PACMED comprising cisplatin (15-25mg/m2 CI × 3d), cytarabine (1.0-1.5g/m2/d × 3), cyclophosphamide (1.0-1.5g/m2/d CI × 3), mesna (1.0-1.5g/m2/d CI × 3), etoposide (0.3-0.5g/m2/d × 3) and DEX (40-100mg/d × 3); additional agents included bortezomib (1.0-1.6mg/m2 on days 1 + 4), thalidomide (100-200mg/d × 4d) or lenalidomide (25-100mg/d × 4) and rapamycin (3mg d 1, 1mg d 2–4) with or without HPC boost. Statistical methods included Cox regression modeling for OS and EFS, along with Kaplan-Meier methodology for survival and cumulative incidence plots. Survival comparisons were made using the logrank test. Results: Baseline characteristics included age >=65 in 18%, B2M >=3.5mg/L in 68% and >5.5mg/L in 38%, CRP >=8mg/L in 60%, LDH >=ULN in 57%, and cytogenetic abnormalities (CA) in 62%. Gene expression profiling (GEP)-defined high-risk (70 genes, R70; 80 genes, R80) was present in 80% and 71%; PR (Proliferation), MF and MS subtypes were present in 44%, 27% and 14%. Prior transplants (Tx) had been given to 96%, including 40% who received 2Tx, 25% with 3Tx and 14% with >3Tx. PR was achieved by 29%, including 14% n-CR and 8% CR. 1-year estimates of OS and EFS were low at 13% and 8%, and median durations were 5 and 3 months. Increased age and high LDH were the only baseline characteristics adversely affecting both OS and EFS. The 29 patients with neither of these risk factors experienced 1-yr OS/EFS rates of 31%/17%; the corresponding values with 1 risk factor (n=47) were 5%/4% and with both risk factors (n=8) 0%/0%. Conclusion: Single cycle PACMED provides only transient tumor control in this heavily pretreated population with 80% displaying GEP-defined high-risk and 62% CA, as a manifestation of end-stage MM. We are currently evaluating repeated cycles of PACMED earlier in the disease course in high-risk MM, in the context of a Super-BEAM transplant regimen.

Abstract Introduction: In addition to disease-specific and age-related factors, type and severity of comorbidities play a relevant role, influence the tolerance of anti-MM-treatment and overall survival (OS). We have identified an impaired Karnofsky Performance Status (KPS), lung and renal impairment as significant risk factors for inferior outcome (Kleber,...Engelhardt. BCJ 2011, Kleber,...Engelhardt. CLML 2013, Engelhardt et al. Haematologica 2014). These variables were combined in a comorbidity score (initial Freiburg Comorbidity Index [iFCI]). The objectives of this analysis were to refine the iFCI ('revised FCI' [rFCI]) by adding host- and disease-specific risk factors, cytogenetics, physical function and quality of life. Moreover, we assessed the benefit of a possible weighting of the rFCI, and compared the rFCI to well-established comorbidity indices, namely Charlson Comorbidity Index (CCI), Hematopoietic cell transplantation-specific comorbidity index (HCT-CI) and Kaplan-Feinstein (KF). Methods: We assessed 803 consecutive patients (pts) treated at our institution between 1997-2012, determining comorbidities as weighted renal, lung, heart, liver, gastrointestinal diseases, KPS, disability, frailty, infection, pain, secondary malignancies, peripheral neuropathy, thrombosis and disease parameters (e.g. cytogenetics). We divided our cohort into a training (n=553) and validation set (n=250) and performed a multivariate analysis via backward selection. Regression coefficients were used to derive weights for the score. Apart from scoring both iFCI and rFCI, we also assessed the CCI, HCT-CI and KF. Results: Our pts showed a typical median age for a tertiary referral center of 63 years (range: 21-93). 26% revealed less favorable cytogenetics, defined as del(17p13), del(13q14), t(4;14), t(14;16) and chromosome 1 abnormalities. Each half of the pts had received either standard chemotherapy or stem cell transplantation. Frequent comorbidities (>30%) were KPS, heart, renal, lung impairment, disability and frailty. Univariate analysis revealed age, renal, lung and heart disease, KPS, disability, frailty, pain and infections as significant. Multivariate risks proved to be advanced age (>70 years), renal, lung, KPS impairment, frailty and cytogenetics with hazard ratios (HR) of 2.2, 1.8, 1.3, 3.2, 1.9 and 1.5, respectively. The rFCI allowed to distinguish low-, intermediate- and high-risk pts with largely different median OS of 11.2, 4.8 and 2.6 years, conclusively confirmed via validation analysis with distinct median OS differences of not reached, 6.5 or 1.4 years, respectively. Weighting of the single risk factors led to a score with maximum points of 39. In order to simplify this score, the single weights were divided by 2 and rounded, which led to a 20-point score (rFCI modified I [mod I]). A 2nd modification led to a 9-point score (rFCI mod II) which was obtained with single risk factors being scored based on their HR. These modified rFCI scores I and II allowed equally well to allocate MM pts in low-, intermediate- and high-risk groups as with the 39-point-rFCI, besides being simpler in their application. Compared to the CCI, HCT-CI and KF, the rFCI remained highly significant. For further comparison, all comorbidity indices in the training and the validation set were divided into two risk groups according to the cut-offs obtained from our initial analyses (BCJ 2011, CLML 2013). Regardless of whether we scored MM pts with the iFCI, rFCI, CCI, HCT-CI or KF, ‘low-risk’ pts had longer median survival than ‘high-risk’ pts. The comparison via median comorbidity indices showed superiority of the rFCI and CCI in the training set and of the rFCI and HCT-CI in the validation set. A further univariate analysis and comparison by dividing the different scores in risk groups based on 25% and 75% quantiles, revealed the highest HR for the rFCI both in the training and the validation set. Conclusions: As comorbidities in MM are frequent, a detailed comorbidity assessment, including host- and disease-specific risk factors, allows an improved risk evaluation in often frail pts. Age, renal, lung, KPS impairment, frailty and cytogenetics are relevant risk factors included in our rFCI. Advantages of the rFCI vs. iFCI are the inclusion of MM-specific risks including cytogenetics, the more accurate assessment of pts' physical conditions, lower prediction errors and its simple clinical applicability.

Abstract We prospectively compared the efficacy of allogeneic PBSCT from an HLA-identical sibling in adults with poor-risk AML or MDS in an early disease status (AML or RAEB type 2 in first CR after chemotherapy or RAEB type 1 with poor prognosis). Poor-risk AML/MDS was defined as the presence at diagnosis of one or more of the following: poor-risk karyoype, normal karyotype with flt-3 duplications or MLL mutations, high level of MRD after consolidation (>0.1%), and, in RAEB type 1, an IPSS3Int-2. Based only on the patients’ age, the transplant protocol consisted in conditioning with cyclophosphamide-TBI and use of CD34+-selected PBSCT (CyTBI-CD34+ group, if £ 50 y.o.) or a reduced-intensity conditioning (RIC) with fludarabine and oral busulphan (FluBu-RIC, If > 50 y.o.). Between 1998 and 2005, 74 consecutive patients entered the study (35 in the CyTBI-CD34+ and 39 in the FluBu-RIC group). Both groups differed in some baseline characteristics, mainly younger age in the CyTBI-CD34+ group (median 42 vs. 59 years, p<0.01), a higher transplant comorbidity index in the FluBu-RIC group (median 0 vs. 3 points, respectively, P<0.01), a higher proportion of AML (with respect to RAEB) in CyTBI-CD34+ group (82% vs 54%, respectively, P=0.02), and a higher proportion of poor-risk karyorypes in the FluBu-RIC group (32% vs 72%, respectively, P<0.01). The median follow-up exceeds 4 years in both groups. All patients had sustained donor-engraftment by day +60, except for one lethal graft failure in the CyTBI-CD34+ group. The 4-year probability of OS was and LFS were similar in both groups (52% and 53% in the CyTBI-CD34+ group vs. 53% and 53% in the FluBu-RIC group, respectively, P>0.8 for OS and LFS). In addition, the 4-year cumulative incidence of non-relapse mortality (NRM) was 25% (95% CI 11–38%) and 22% (95% CI 5–39%), respectively (P>0.8), while the incidence of relapse was 22% (95% CI 5–39%) and 25% (95% CI 6–44%), respectively (P>0.8). In univariate analysis, the only variable that decreased OS and LFS by increasing NRM was the patient male/donor female sex combination (n=18 cases). The OS and NRM in these 18 cases were 37% and 40%, respectively, while the 56 cases with other sex combinations had much better outcomes (66% OS and 8% NRM, P=0.004 and P==0.001 for the comparison of OS and NRM, respectively). Trends were seen for improved OS and lower NRM in the CyTBI-CD34+ group in patients less than 40 years of age (P=0.1) and in patients receiving higher doses of CD34+ cells/kg in the FluBu-RIC group (P=0.1). Our single-center results suggest comparable outcomes for RIC alloPBSCT in high-risk adults with poor-risk AML and MDS in an early disease phase.

Abstract Abstract 4848 Background Myelodysplastic syndrome(MDS) belong to the most common hematological diseases however epidemiological data on MDS are sparse. Until 2008 there were no data about epidemiology of MDS in Poland. Methods From 03.2008-05.2009 we have registered 966 patients in Polish MDS Registry. We have included only alive patients of various time of diagnosis. Patients from 22 centers were diagnosed according to WHO 2001 criteria. Results There were 508(53%)males and 458(47%) females. Median age at diagnosis was 70(range 19-99). Under 50 were 83(9%) cases with preponderance of females- 51 cases( males 32cases), between 50-70 there were 353(41%) cases, half of the patients-432(50%) were above 70( 247 males and 185 females).Prior chemotherapy and/or radiotherapy had 37((3,8%) patients. Distribution of MDS subtypes was as follows: RA-170(20%) cases, RARS-58(7%), RCMD-244(28%), RCMD-RS-18(2%), RAEB-1-120(14%), RAEB-2-169(19,5%), 5q- -40(4,6%), MDS-U-44(5%).In 103(10%) subtype was not done. Karyotype was available in 276(28%) cases. Cytogenetic risk groups were: low risk-182(68%), intermediate-52(20%) and high risk-33(12%). The most frequent cytogenetic results were: normal karyotype 44%, isolated 5q deletion 19%, complex karyotype 6%, 5q deletion + another one change 3% and 5q deletion with at least 2 changes 3%. According to IPSS risk groups low risk was found in 61( 22%) of cases, intermediate-1 -130(48%), intermediate-2-47(17%) and high risk in 31(11,5%). Median values of Hb was 9,1 g/dL, plts 129 G/L, ANC 1,7 G/L. RBC transfusion dependent were 429(44%) patients and platelet transfusion dependent were 100( 11%) pts. At least 2 U/month RBC transfusion requirement was 140(14%) patients. Serum ferritin level was assessed in 530 cases-171 of them( 32%) had higher than 1000μg/L level. Conclusions We have observed predominance of females among MDS patients under 50. Half of the patients had RA or RCMD subtype. Isolated 5 q deletion was the most frequent cytogenetic abnormality. Forty four percentage of patients was RBC transfusion dependant. Serum ferritin level was significantly elevated in 32% of assessed patients at the moment of MDS diagnosis.

Abstract Abstract 4800 Background: Despite availability of novel agents, many MM patients still relapse and require salvage interventions. In the Arkansas program, we have attempted to procure initially sufficient hematopoietic precursor cells, for use in high-dose therapy salvage regimens once phase I-II trials have been exhausted. We are reporting on the efficacy in terms of response rate, EFS and OS of ARMM patients receiving S-BEAM. Patients and Methods: S-BEAM comprised standard BEAM (carmustine 300 mg/m2 on day 1, etoposide 200 mg/m2 days 1–4, cytarabine 400 mg/m2 days 1–4, melphalan 140 mg/m2 on day 5) with the addition of cisplatin (10-12.5mg/m2/d CI × 5d), bortezomib (1.3-1.5mg/m2 on days 1 + 4), thalidomide (100-200mg/d for 5 days) or lenalidomide (25-100mg/d for 5 days), DEX (40-100mg/d for 5 days) plus rapamycin (3mg d1, 1mg d2-5). Statistical methods included Cox regression modeling using significance level 0.05 and Kaplan-Meier methodology for all figures. Comparisons within figures were made using the log-rank test. Results: The characteristics of 147 patients treated included prior transplant (Tx) in 67% (2Tx, 29%; =>3Tx, 11%), and prior exposure and resistance in virtually all patients (92%) to bortezomib, thalidomide, lenalidomide applied in VTD, VRD or with chemotherapy VTD-PACE. Pre-S-BEAM high-risk features included low albumin (<3.5g/dL; 66%) high B2M (>=3.5mg/L; 32%), high LDH (>=ULN; 44%), and presence of cytogenetic abnormalities (CA) in 70%. Clinical outcomes included at least PR in 62% including 48% with n-CR and 29% with CR. Two-year estimates of EFS and OS were 29% and 33%; TRM within 60 days was 3%. At 4 years, 23% remain alive and 15% event-free. Independently significant variables affecting both OS and EFS adversely included, in a model without GEP, high B2M (>5.5mg/L), high LDH (>=ULN), low hemoglobin (<10g/dL) and CA, whereas achieving PR improved survival. Based on R2-driven independent adverse variables, B2M, LDH and CA were linked to poor outcomes, with 1-year estimates of OS/EFS of 83%/69% with 0, 63%/52% with 1, 25%/9% with 2, and 13%/0% with more than 2 high-risk parameters. Gene expression profiling (GEP)-defined high-risk was present in 55% (70 genes, R70) and in 47% (80 genes, R80); delTP53 was noted in 21% and Proliferation Index (PI) score >=10 in 42%. When GEP data were included in a subset of 103 patients, high-risk designation, high LDH and age >=65 were identified on the basis of highest R2 values (49% for OS, 41% for EFS). Among 28 patients lacking any of these 3 features, 1-year OS/EFS was 83%/67%, with 1 variable (n=36) 53%/38%, with 2 (n=31) 22%/6% and with 3 (n=8) 0%/0% (both P<0.001). Applying a cut-off of 2 adverse variables, the 60 patients with 2 or fewer enjoyed 2-year OS of 49% and EFS of 48%, as opposed to 7% and 4%, respectively, among the remaining 36 patients with more than 2 risk features. Conclusion: S-BEAM provides effective salvage therapy in ARMM with 60-day TRM of 3% and prognostic factor-dependent survival expectation. We are currently evaluating S-BEAM earlier in the disease course, with PAC-MED as induction prior to and as consolidation after S-BEAM in high-risk myeloma. Overall survival by number of non-GEP risk factors (B2M, LDH, CA), selected based on maximum R2 value (38% for OS, 33% for EFS) Overall survival by number of risk factors (age, LDH, GEP high-risk), selected based on maximum R2 values (49% for OS, 41% for EFS) Disclosures: No relevant conflicts of interest to declare.
