Abstract Abstract 3562 Aim of the present study was to evaluate the clinical outcome of a large series of younger patients with symptomatic multiple myeloma (MM) who were enrolled in two subsequent clinical trials of thalidomide-dexamethasone (thal-dex) incorporated into double autologous stem-cell transplantation (ASCT) to support high-dose melphalan (200 mg/m2). In both studies, thal (100 mg/day for the first 14 days and then 200 mg/day) and pulsed dex (between 480 and 160 mg per cycle), were administered from the onset until the second ASCT. The analysis was performed on an intention-to-treat basis on a total of 593 patients who were followed for a median of 36 months. The best VGPR and CR rates were 69% and 35%, respectively. The median duration of CR was 66 months. Median TTP and PFS were 53 and 44 months, respectively. The 5-year projected rates of TTP and PFS were 46% and 38%, respectively, while the corresponding value for OS was 67%. More than 80% of the patients were screened at diagnosis for the presence of cytogenetic abnormalities by FISH analysis. Forty-five percent of patients had del(13q), while t(4;14) and del(17p) were found in 16 % and 7 % of patients, respectively. The presence of del(17p) and/or t(4;14) was associated with a significantly shorter 5-year projected TTP, PFS and OS in comparison with the absence of these abnormalities, indifferently from the presence or absence of del(13q) (TTP: 30% vs 53%, respectively P=0.0000; PFS: 28% vs 45%, respectively, P=0.0000; OS: 53% vs 69%, respectively, P=0.0000). OS and PFS curves of patients carrying del(13q) alone were almost superimposable to those of patients without cytogenetic abnormalities, while TTP was significantly shorter for patients with del(13q) alone (5-year projected rates: 40% vs 53%, respectively, P=0.04). Patients carrying del(17p) in the absence of t(4;14) had similar 5-year projected TTP and PFS as compared with t(4;14) positive but del(17p) negative patients. However, OS was significantly shorter for the subgroup with del(17p) and absence of t(4;14) in comparison with that of patients carrying t(4;14) without del(17p) (5 year projected rates: 18% vs 70%, respectively, P=0.03). In a multivariate analysis, presence of del(17p) and high beta2-m at baseline were the most important variables adversely influencing TTP (HR: 2.3, P=0.001 and HR: 1.8, P=0.002, respectively), PFS (HR: 2.0, P=0.001 and HR: 1.9, P=0.001, respectively), and OS (HR: 3.9, P=0.000 and HR: 2.0, P=0.005, respectively). Additional variables predicting for shorter TTP and PFS were the presence of t(4;14) (HR: 1.8, P=0.004) and of del(13q) (HR: 1.6, P= 0.009). Also the quality of best response to the overall treatment program influenced clinical outcomes. In particular, patients achieving CR had a significantly longer PFS and OS than those achieving a VGPR (PFS: median 68 vs 40 months, respectively, P=0.007; 5-year projected OS rates: 84% vs 70%, respectively, P=0.01). In conclusion, incorporation of thal-dex into double autotransplantation failed to overcome the poor prognosis conferred by del(13 q), t(4;14) and del(17p). In a multivariate Cox regression analysis, del(17p) and high levels of serum beta2-m at diagnosis were the strongest variables adversely influencing PFS and OS. In comparison with the presence of t(4;14) but absence of del(17p), patients carrying del(17p) without t(4;14) had a significantly shorter OS, possibly due to their worst outcome after relapse. Presence of del(13q) alone conferred a significantly shorter TTP, but did not have an adverse impact on OS due to the favorable role of effective salvage therapies incorporating either bortezomib or lenalidomide.

Abstract BACKGROUND High dose therapy followed by autologous stem cell transplantation (ASCT) remains the standard of care, especially in Europe, for young and eligible multiple myeloma patients (usually younger than 65 years old). Immunoparesis is defined as a reduction (below the lower normal limit) in the levels of 1 or 2 uninvolved immunoglobulins (Ig) and it is related to a reversible suppression of B lymphocytes that correlates inversely with disease stage. B Lymphocyte reconstitution begins at 3 months after ASCT, with maximum B lymphocyte levels at 1 year after ASCT. AIMS The goal of the present study was to investigate the role of the immunoparesis recovery after ASCT as predictor of relapse or progression in multiple myeloma (MM). METHODS We reviewed medical records of MM patients who underwent to ASCT at University Hospital of Salamanca between 1992 and 2013. The primary endpoint was time to relapse or progression from ASCT. Ig (Ig G, Ig A e Ig M) were collected at the time of diagnosis, before ASCT, every 3 months during the first year after ASCT, and every year up to 5 years after ASCT among eligible patients until the relapse or disease progression. RESULTS 106 multiple myeloma patients who underwent ASCT were included in the analysis. Conventional chemotherapy was administered as induction regimen in 69 patients (65%), whereas novel agents were used in 37 patients (35%). Most patients had immunoparesis at diagnosis (91%) and at the moment of ASCT as well (94%). After a median follow-up of 62 months, median time to progression or relapse (TTP) from ASCT was 31 months (95 % CI: 24.1 - 37.1 months). MM patients with immunoparesis 1 year after ASCT had a significantly shorter median TTP as compared with patients without immunoparesis (33.5 months vs 94.2 months; HR: 2.14, 95% CI: 1.13-4.05; p=0.019). In the group of patients with reduction of both Igs, median TTP was slightly inferior than in the group with reduction of only one of them(33.5 vs 36.4 months, p=0.03). Presence of ISS 3, high-risk cytogenetics at diagnosis, less than partial response achieved before and three months after ASCT were also identified as predictors of progression. Multivariate analysis selected immunoparesis 1 year after ASCT as an independent variable for relapse or progression (HR: 5.97, 95% CI: 1.63-21.88; P=0.007). CONCLUSIONS The lack of immunoparesis recovery at 1 year after ASCT in MM patients is associated with significantly higher risk of relapse or progression and this group of patients could potentially benefit of continuous treatment after ASCT to enhance the immune recovery.

Abstract Abstract 1821 Introduction: PN is an important complication of MM and its incidence has been further increased after the introduction of the novel agents thalidomide and bortezomib. In a phase 3 trial comparing TD with VTD as induction therapy prior to and consolidation therapy after double autologous stem-cell transplantation for previously untreated MM patients, the VTD arm was significantly superior over TD in terms of improved rates of complete or near-complete response (CR/nCR) (the primary study endpoint) and progression free survival (PFS). Toxicity of VTD and TD regimens, including PN, was a secondary study endpoint. Methods: We performed a subanalysis of the study to assess the frequency, reversibility, risk factors and molecular markers associated with treatment-emergent PN. PN was graded by use of National Cancer Institute's Common Toxicity Criteria (NCI CTCAE) version 3.0. Since grade 1 PN could be misinterpreted and does not interfere with the daily activities, only patients who developed PN of at least grade 2 were evaluated. A total of 474 patients (of whom, 236 randomized to the VTD arm and 238 to TD) were stratified according to the development or not of grade ≥2 neurological adverse events (NAEs). Gene expression profiles (GEP) of pre-treatment CD138+ bone marrow plasma cells (BMPCs) were analyzed in a subset of 127 VTD-treated patients for whom biological samples taken at diagnosis were adequate for genomic analysis. GEP experiments were performed using the Affymetrix HG-U133 Plus 2.0 platform and class comparison of groups of array was done with one-way ANOVA Partek Genomic Suite (version 6.4). Results: Occurrence of PN throughout the entire treatment program was significantly higher in the VTD arm compared with TD. In particular, the rate of grade ≥2 PN was 35% vs 10% (p<0.001), and grade ≥3 was 15% vs 2.5% (p<0.001), respectively. Most of NAEs occurred during the induction phase (52% in VTD and 70% in TD arms), while a minority were seen during consolidation therapy (6% in VTD and 8% in TD). Median time to onset of grade ≥2 PN was 83 days in the VTD arm compared with 37.5 days in TD arm (p=0.04). Overall, 89% of patients on VTD and 95% on TD had a complete resolution of PN within a median of 70 and 61 days (p=0.6), respectively. An improvement to at least grade 1 was recorded in 94% of patients in the VTD arm and in 95% on TD within a median of 78.5 and 61 days (p=0.4), respectively. Three patients (1%) on VTD and none on TD discontinued treatment due to neurological toxicity. Notably, development of grade ≥2 PN did not affect the rates of CR/nCR, and both time to progression (TTP) and PFS. By univariate analysis, characteristics of patients at baseline, including age, MM isotype, ISS stage and cytogenetic abnormalities such as del(13q), t(4;14) or del(17p), did not influence the development of grade ≥2 PN in both arms. GEP were analyzed in 127 patients assigned to the VTD arm (44 with and 83 without treatment-emergent grade ≥2 PN). Patients experiencing a grade ≥2 PN were characterized by the differential expression of 184 genes (p<0.01). The genes showing the highest change in expression included NRN1 (involved in the axonal regeneration), GSTM1 (involved in the detoxification of electrophilic compounds by conjugation with glutathione), DCTN1 (whose mutations are associated in specific types of disease-associated axonal degeneration). GeneGO® pathway analysis of differentially expressed genes showed enrichment for genes mainly implicated in the regulation of cytoskeleton rearrangement and the axonal guidance: indeed, several genes, which are involved in the signal transfer from semaphorin and ephrin to the cytoskeletal and motor proteins resulted differentially expressed in patients who developed grade ≥2 PN (SEMA6A, SEMA4B, ACTA2, EPHA5, NEB). Conclusions: Although VTD incorporated into double ASCT was associated with a higher incidence of grade ≥2 PN compared with TD, the probability of complete resolution or improvement to at least grade 1 was comparable in both VTD- and TD-treated groups. Importantly, NAEs did not adversely affect the rate of CR/nCR, and TTP and PFS. No relationship between development of PN and both patient demographics and disease characteristics was observed. Conversely, GEP analysis of BMPCs from patients with VTD-induced PN showed the significant deregulated expression of genes involved in the nervous system function.

Abstract To assess the therapeutic value of sequential high-dose therapy (SHDT) including autologous stem cell transplantation in chronic lymphocytic leukemia (CLL) we performed a risk-matched comparison between 66 patients who had undergone a uniform SHDT regimen and a database of 291 patients treated conventionally. Matching variables were age, Binet stage, IgVH (variable region of the immunoglobulin heavy chain) gene mutational status, and lymphocyte count. Forty-four pairs fully matched for all 4 variables were identified. Patient groups were well balanced for additional risk factors including adverse genomic abnormalities and CD38 expression. With an overall median follow-up time of 70 and 86 months, respectively, survival was significantly longer for the SHDT patients than for the conventionally treated patients when calculated from diagnosis (hazard ratio [HR] 0.39; P = .03 [log rank]) or from study entry (HR 0.32; P = .006). The benefit for the SHDT group remained significant when the analyses were restricted to those 58 patients who had an unmutated VH status. Cox regression analysis confirmed SHDT as independent favorable prognostic factor for survival from diagnosis (HR 0.38, P = .04) as well as from study entry (HR 0.38, P = .03). These data suggest a survival benefit for patients with poor-risk CLL receiving SHDT during the course of their disease. (Blood. 2004;103:2850-2858)

Abstract Abstract 4528 Background: The role of high-dose melphalan (HDM) followed by autologous stem cell transplantation (ASCT) in the treatment of Multiple Myeloma (MM) continues to evolve in the era of novel agent. Although data from clinical trials with novel agens are very promising, it is evident that ASCT remains the golden standard for all available patients; moreover combination with proteasome inhibitors and immunomodulatory agens will ensure further benefits and prolongation of overall survival to patients. Aim: To investigate the indication, frequency and results of HDM and ASCT in MM patients in the era of novel agens. Methods: Before inclusion to the Registry of Monoclonal Gammopathy (RMG) of the Czech Myeloma Group (CMG), all persons signed the informed consent forms. Out of 1448 newly diagnosed patients (654 aged≤ 65 years) reported in the RMG in the period 2007–2011, 26.7% (386/1448) underwent ASCT as part of primo therapy. A cohort of 229 patients underwent ASCT as part of the first, second and third relapse (R1–3) treatment in the same time period. Time to progression in different disease settings, objective response rate, and safety were included as exploratory outcomes. Efficacy was assed using the IMWG criteria. A distinctive aspect of this analysis involves comparison of frequency of ASCT during this period of time. Results: A total of 59% (386/654) of newly diagnosed patients under 65 years underwent ASCT as part of primo therapy. Frequency of indication between patients with age ≤ 65 years was similar (56–63%) during the last five years. Melphalan 200mg/m2 was the most frequently used HDM (94%) in primo therapy. The same was true for R1 (73%), R2 (46%) but not R3 where most frequent (49%) HDM was melphalan 100mg/m2. Transplant related mortality day+100 ranged between 0.8 to 1.1% during five consecutive years for all treatment settings together and was zero for primo therapy in the year 2007 and 2009–10. Overall responses to ASCT (primo therapy vs. R1 vs. R2 vs. R3) were: ORR 93% (30.5%≥CR) vs. 93% (20%≥CR) vs. 72% (8%≥CR) vs. 54% (4.1%≥CR). Medians of Time to Progression (TTP from the time of ASCT; primo therapy vs. R1 vs. R2 vs. R3) were: 26.2 vs. 15.6 vs. 5.8 vs. 4.8 months and the difference were statistically significant (p<000.1). Conclusion: ASCT is a safe treatment strategy in MM independently of disease advance, although for patients with more advanced disease, reduced dose of melphalan (100mg/m2) should be considered. ASCT is very effective treatment not only for newly diagnosed MM patients but also for patients in the first relapse. The indication in relapse setting should be considered more frequently than is currently common in the shadow of enthusiasm for novel drugs.

Abstract Introduction: Previous trials have shown that autologous stem cell transplantation (ASCT) is superior to conventional chemotherapy in terms of remission rate and PFS in younger MM patients. Concerns about toxicity and potential efficacy of ASCT in older MM patients lead most centers to limit ASCT indications to patients aged <65 years. However, at the era of novel induction regimens, and because of better patient selection and supportive care, ASCT may prove to be a valid treatment option even in older MM patients. Therefore, some investigators are questioning the widely used 65 years age limit. Patients and Methods: We prospectively analyzed the outcomes of 56 consecutive MM patients who had received ASCT between September 2012 and September 2014 in 6 institutions in France (protocol ClinicalTrials.gov Identifier: NCT01671826). Patients were newly diagnosed MM. For induction therapy, all patients received a bortezomib-based induction regimen (VD, VTD, VCD, or VRD, 4 to 6 cycles) according to center's local guidelines. Mobilization was performed with G-CSF or G-CSF+cyclophosphamide and plerixafor whenever needed. High-dose chemotherapy consisted of either 140 mg/m2 or 200 mg/m2 Melphalan. A short two months consolidation phase post ASCT was allowed (lenalidomide-dexamethasone, VD, VTD, VCD or VRD). No maintenance treatment was given. Response, disease progression and relapse were defined according to the IMWG uniform response criteria. All patients signed an informed consent form according to the EBMT guidelines. Results: At time of diagnosis, median age was 67 (range, 64-74) years with 23% of patients being >70 years. There were 30 males and 26 females. The immunoglobulin subtype was IgG (n=29), IgA (n=15), light chain (n=10), other (n=2). The Salmon and Durie stage was III in 89% of cases (n=47), and the ISS score was I (n=18; 35%), II (n=19; 37%), III (n=14; 27%). Patients had high risk cytogenetics features (t(4;14) and/or del17p) in 9 cases (16%). 10% of patients had a serum creatinine level >176 micromol/L. None of the patients underwent hemodialysis. The Sorror comorbidity score was 0 (34), 1 (6), 2 (2), 3 (6), 6 (1), unknown (7). The median age at time of ASCT was 68 years, and the median time from diagnosis to ASCT was 5 months. In an intention to treat analysis, out of 56 patients, 6 patients could not proceed to ASCT because of an early infectious death (n=1), serious comorbidity (n=2), disease refractoriness to induction (n=1), and failure to collect an adequate PBSC graft (n=2). A median of 5.31x106/Kg CD34+ cells could be collected. Disease status at time of ASCT was: CR (n=12; 24%), VGPR (n=19; 38%), PR (n=17; 34%), and SD/non-responding (n=2; 4%). The conditioning regimen consisted of 140mg/m² melphalan in 18 cases (36%) and 200mg/m2 in 32 patients (64%). Moreover, 4 patients (8%) received a tandem ASCT. The median time for neutrophils and platelets engraftment was 12 days. The day-100 post ASCT non-relapse mortality was 0% and the 2-year NRM was 4.2% (95% CI:[0.3-18.3]). The overall response rate at day 100 was 96% (CR: 34%, VGPR: 47%, PR: 15%, SD/non-responsive: 4%). At 3 months post ASCT, 82% patients were able to receive the planned post ASCT consolidation treatment. After a median follow-up of 12 months, the estimated progression-free (PFS) and overall survival (OS) rates at 2 years were 76% (95%CI: [61.6-94.1]) and 88% (95%CI: [76.7-100]), respectively. The incidences of infectious complications post ASCT, and response rates were comparable between the two melphalan dose levels (p=0.28). However, in the univariate analysis, the 200 mg/m2 melphalan conditioning group showed a better OS rate compared to the 140 mg/m2 group (1-year OS: 100% vs. 67%; p=0.012). Conclusion: These prospective multicenter results indicate that ASCT is a safe and effective treatment modality for elderly, but fit MM patients at the era of novel induction agents. Of note, patients above age 70 did not experience a worse prognosis. Thus, age per se should not be used as an exclusion criterion for ASCT. Longer follow-up data will be presented, but these results already set the frame for a randomized comparison to the non-transplant approaches in this patients' subgroup.

Safety And Efficacy

Introduction Multiple myeloma (MM) patients with renal impairment (RI), especially dialysis-dependent (DD) RI, have poorer outcomes than MM patients with normal renal function. Autologous stem cell transplantation (ASCT) is a treatment option, but there is concern at a perceived higher risk of complications which may be limiting consideration of the use of ASCT in this population. The evidence is inconsistent among studies and interpretation is complicated by heterogeneous datasets, some dating to before the availability of novel agents. Finally, the reversibility of RI following ASCT is an important prognostic factor for both survival and quality of life. Aim To evaluate the safety and efficacy of ASCT in MM patients with DD RI transplanted in EBMT centres between 1997 and 2017. Methods Baseline characteristics at diagnosis, patient treatment regimens and clinical outcomes were collected using standardised report forms. OS was defined as the period between the date of ASCT and the date of death or the date of last observation. PFS was defined as the period between the date of ASCT and date of progression/relapse or death of any causes or the date of the last observation. Cox proportional hazard regression analysis was applied to assess risk factors for progression and death. Survival curves were plotted by the Kaplan-Meier method and compared using log-rank test. P&lt;0.05 was judged as statistically significant. Results A total of 109,959 adult MM patients are registered in the EBMT database as having undergone ASCT between 1997 and 2017. We further analysed 118 DD MM patients who had a first ASCT during this period. The median (range) age was 57 (27-71) years. Seventy (59%) patients were males. Forty nine patients (49/94 patients, 52%) had Karnofsky score ≥90. One hundred and ten patients were treated with hemodialysis and eight with peritoneal dialysis. A total of 68 (58%) patients had Light Chain MM, 43 kappa and 25 Lambda. In first-line induction therapy, 47/76 (62%) patients received bortezomib-based regimens. Forty-four (37%) patients achieved at least VGPR pre-ASCT. The median time from diagnosis to ASCT was 0.7 years (0.3-4.9). Melphalan doses were as follows: 140 mg/m2 (n=55, 67%), 70-100 mg/m2 (n=15, 18%), and &gt;140 mg/m2 (n=12, 15%). The times to Neutrophil (&gt;0.5) and Platelet (&gt;20) engraftment were 12 (10-37) and 14 (4-128) days, respectively. The 30-day and 100-day transplant-related mortality (TRM) rates were 0.0% and 0.9%, respectively. ASCT was associated with a significant deepening of response (at least VGPR pre- vs post-ASCT: 36/93 (39%) vs 48/93 (52%), p &lt; 0.001). The median PFS was 37 months (95% CI: 24-43) and 5-year PFS was 31% (95% CI: 20-41). The median OS was 102 months (95% CI: 67-129). Five-year OS post-ASCT was 62% (52-72) and 10-year OS 36% (17-55). Thirty-one (26%) DD MM patients achieved dialysis independence. There were no differences in PFS or OS when comparing the 1997-2007 and 2008-2017 cohorts: 5-year PFS - 28% (6-49) vs 31% (19-43) (p=0.7) and 5-year OS - 61% (38-84) vs 63% (51-74) (p=0.9), respectively. On univariate analysis of factors affecting PFS, achievement of an Overall Response Rate (ORR) (CR+VGPR+PR vs. Other) pre-ASCT was associated with a lower risk (HR 0.467, p=0.032) and older age (&gt;55 years) with a higher risk (HR 1.786, p=0.035) of post-ASCT progression. Age higher than 55 (HR 2.033, 95%CI: 0.992 - 4.166, p=0.053) increased and achievement of at least VGPR pre-transplant (HR 0.494, 95%CI: 0.224 - 1.091, p=0.081, on the verge of statistical significance) decreased the risk of death. Conclusion To the best of our knowledge, the DIADEM study is the largest analysis of ASCT in DD MM pts to date. This cohort of 118 unselected patients had an OS comparable to patients without RI. This may reflect patient selection based on younger age, Karnofsky scores and pre-ASCT response. The low TRM and excellent outcomes support consideration of the use of ASCT in pts with DD RI. Notably, more than a quarter of patients became dialysis independent, an outcome likely to confer an improved Quality-of-Life.. These results can also inform the debate around the role of renal transplantation in younger DD MM patients who do not achieve dialysis independence.

High Dose Melphalan

Abstract Introduction Renal impairment occurs in 20-30% of newly diagnosed multiple myeloma patients, requiring dialysis for up to 10% of patients.Recent results ofan IFM (Intergroupe Francophone du Myélome) study confirm the effectiveness of high dose melphalan followed by Autologous Hematopoietic Stem Cell Transplantation (ASCT) as first line therapy in multiple myeloma patients. Most centers exclude renal failure patients due to concerns of toxity, because data are limited for safety and toxicity to consider. This current retrospective study observes toxicity and outcome in 55 multiple myeloma patients with severe renal impairment, undergoing high dose melphalan and ASCT, in the age of bortezomib. Methods Using the PROMISE database, 55 multiple myeloma patients French SFGM-TC centers were included from January 2002 to November 2012. Characteristics of the patients presenting with creatinine clearance less than 30ml/min at time of ASCT were included. Results Median age was 61 (40-75) years old. Thirty-nine (71%) presented free light chain myeloma. Twenty-three (42%) patients were on dialysis at the time of ASCT and during hospitalization. Thirty-one (56%) patients received bortezomib as induction therapy. Melphalan dose ranged from 75mg/m² to 200mg/m². Thirty (55%) patients were treated with a dose of 140mg/m². Median delay between diagnosis and ASCT was 5.3 months. Among 50 patients evaluated for toxicity, respectively febrile neutropenia and mucositis occurred in 92% and 90% of patients. Half of the mucositiscases were grade 3-4. The median number of days before neutrophil and platelet recovery was respectively 12 days (10 - 34) and 16 days (7 - 331). Two patients experienced cardiac toxicity (grade 1-2), and 4 patients neurologic toxicity (grade 3 for one patient). Among 51 patients evaluated for response, 12 patients (24%) were at least in Very Good Partial Response (VGPR) before ASCT, including 5 in Complete Response (CR). All of them were treated with bortezomib as induction therapy. After ASCT, 30 patients (58.8%) reached at least VGPR (22 CR and 8 VGPR). Among 30 patients in VGPR or more post ASCT, 22 (73%) were treated with bortezomib before ASCT. Table 1 shows the responses. Fourteen (26%) received two ASCT. One patient died from toxicity (cerebral bleeding during second ASCT). There is no argument for dramatic response improvement with this procedure in comparison to single ASCT. After a median follow-up of 55 months, median progression free survival (PFS) was 55 months, and median overall survival (OS) was 95 months. In multivariate analysis, dose of melphalan at 140mg/m² was significantly correlated with a better PFS (p=0.006), compared to 100mg/m² (or less) and to 200mg/m². During follow-up 29 patients (54%) relapsed and 25 died. The main causes of death were relapse and disease progression (72%). There were only 3 cases of treatment related mortality (TRM). At day 100, the cumulative incidence of TRM was 6%. Among 23 dialysis patients, 6 patients (26%) became dialysis independent, but not during ASCT. Thirteen (56%) were still alive at last follow-up, and 8 (34%) experienced relapse. Median PFS for this subgroup of patients was 73 months. Conclusion With an acceptable TRM, without major toxicities, high dose melphalan (140mg/m²) following by ASCT appears to be a real benefit for multiple myeloma patients with severe renal failure. This includes patients on dialysis. Response is dramatically improved by this procedure, with median PFS similar to that of patients with normal renal function. Finally, adjunction of bortezomib as induction therapy also improves the efficacy of ASCT. Disclosures Augeul-Meunier: gilead: Consultancy; janssen: Consultancy.

Abstract As previously reported, genetic variability in xenobiotic metabolism (GSTP1 and NQO1), multidrug resistance (MDR1), folate transport (SLC19A1) and DNA synthesis (TYMS) can influence the outcome after chemotherapy and autologous transplantation in patients with multiple myeloma (MM) (Maggini et., Leuk Res 2007 in press; Buda et al., Leuk Res 2007, 31(8):1029–30; Buda et al., BJH 2007, 137(5):454–6; Maggini et al., Leukemia 2007, 21(1):176–8). To test the reciprocal influence of the examined polymorphisms on the outcome, multivariate analyses were performed on 98 patients receiving DAV regimen, followed by conditioning regimen with melphalan and autologous stem cell transplantation (ASCT) in 84 cases. As shown in table I, a worse outcome following DAV therapy was significantly associated with GSTP1 G/G, SLC19A1 T/T and TYMS A/A genotypes. Only a borderline effect was seen for NQO1 T/T carriers. After ASCT, no significant influence of the analysed polymorphisms was observed, but a higher percentage of responders presented the SLC19A1 T/T genotype. A significantly improved overall survival (OS) was found in patients carrying SLC19A1 T/T genotype or MDR1 T allele (Cox regression analysis, p=0.01). Multivariate analyses confirmed the previously reported findings: the estimated effects are comparable, even though the significance resulted slightly reduced as expected for multiple comparisons. These preliminary results, if sustained by extended analyses, suggest that these polymorphisms could be regarded as pharmacogenetic markers and as prognostic factor in order to predict the outcome of MM patients. Table I Multiple genotype testing of MM patients are responders (R) versus non-reponders (NR) to DAV therapy (CT) or ASCT by unconditional logistic regression analysis.
