Abstract A panel of members of the 2009 International Myeloma Workshop developed guidelines for risk stratification in multiple myeloma. The purpose of risk stratification is not to decide time of therapy but to prognosticate. There is general consensus that risk stratification is applicable to newly diagnosed patients; however, some genetic abnormalities characteristic of poor outcome at diagnosis may suggest poor outcome if only detected at the time of relapse. Thus, in good-risk patients, it is necessary to evaluate for high-risk features at relapse. Although detection of any cytogenetic abnormality is considered to suggest higher-risk disease, the specific abnormalities considered as poor risk are cytogenetically detected chromosomal 13 or 13q deletion, t(4;14) and del17p, and detection by fluorescence in situ hybridization of t(4;14), t(14;16), and del17p. Detection of 13q deletion by fluorescence in situ hybridization only, in absence of other abnormalities, is not considered a high-risk feature. High serum β2-microglobulin level and International Staging System stages II and III, incorporating high β2-microglobulin and low albumin, are considered to predict higher risk disease. There was a consensus that the high-risk features will change in the future, with introduction of other new agents or possibly new combinations.

Abstract BACKGROUND: In the last decades, multiple myeloma (MM) prognosis has been changing dramatically. Induction with novel agents, followed by high-dose melphalan and autologous hematopoietic stem cell transplantation (aHSCT) is the standard of care for newly diagnosed (ND) and transplant-eligible MM patients (pts). In 2015, a new score was validated [Revised International Staging System (R-ISS)], including data related to high-risk cytogenetic abnormalities (CA) [del(17p) and/or t(4;14) and/or t(14;16)] and serum lactate dehydrogenase (LDH) levels. Few recent studies have supported R-ISS as a reliable prognostic tool for estimating survival in MM pts submitted to aHSCT. AIMS: To determine whether R-ISS is a valid risk model for predicting progression free survival (PFS) and overall survival (OS) among a cohort of real-life aHSCT pts. METHODS: We conducted a single center retrospective study of ND symptomatic MM pts treated with novel agents (bortezomib, thalidomide or lenalidomide) undergoing aHSCT between Jan/2007 and Dec/2017. We excluded all pts with no available information about ISS, LDH and CA [detected by fluorescence in situ hybridization (FISH)]. Response to treatment was evaluated according to the International Myeloma Working Group consensus criteria (2016). Statistical analysis was performed using STATA v.14.2 and significant levels were set at p<0.05. RESULTS: From the total number of 186 pts submitted to aHSCT, only 81 (45%) pts presented criteria to be included in our analysis; 62% were male, with a median age at aHSCT of 60y (28-70). IgG was the most frequent subtype (59%), followed by IgA (20%). At diagnosis, 38% of pts presented anemia, 14% renal impairment (RI), 20% hypercalcemia, 63% bone disease (BD) and 32% extramedullary disease (EMD). According to ISS, 30 (37%) pts presented stage I, 30 (37%) stage II, and 21 (26%) stage III at diagnosis. There were 38% pts with high-risk CA: 24% with del17p; 19% with t(4;14), and 20% with t(14;16). High LDH levels was seen in 48% of pts. Pts were re-staged at diagnosis according to R-ISS, resulting 17% in stage I, 61% in stage II, and 22% in stage III. Thus, 16 (20%) pts previously categorized as ISS I and 3 (4%) pts as ISS III were re-classified as R-ISS II. Median time from diagnosis to aHSCT was 9.7 months. All pts received induction therapy with novel agents (a bortezomib-based therapy in 89% of pts and an IMID-based in 12%), with 81% of pts responding to first line induction; 19% were refractory. At the time of aHSCT, all pts presented at least on partial response (PR) [62% at least very good partial response (VGPR)], with an increase in the proportion of pts in complete response (CR) from 15% to 20% before and after aHSCT, respectively. Maintenance therapy was performed in 31% of pts (79% thalidomide; 21% lenalidomide). At a median follow-up of 33.4 months, median OS had not been reached. Two-years OS was 62%. Median PFS from aHSCT was 67.4%.Neither high-risk CA nor high LDH levels individually predicted lower OS and PFS (p=NS). The 2-year OS for R-ISS I, II and III was 86 %, 61% and 44%, and the 2-year PFS was 79 %, 63% and 39%, respectively. In our cohort we observed statistical significance differences between R-ISS I and III at 2 years in what concerns PFS (p=0.025) and OS (p=0.017) . No differences were seen in between other R-ISS categories. When we stratified R-ISS stage II in two subgroups based on the presence or absence of high-risk CA no differences were found. Pts classified as R-ISS III presented anemia (p<0.001) and RI (p=0.001) more frequently, but no differences concerning hypercalcemia, BD or EMD. CONCLUSIONS: In our real-life cohort, R-ISS at diagnosis was a reliable tool only to predict both OS and PFS between R-ISS I and III and not between other R-ISS subgroups. The main reasons that explain the absence of significance between all R-ISS subgroups were probably the very low number of pts with available cytogenetics compared with the total number of pts submitted to aHSCT in our center and the short follow up of our study. Larger real-life studies with a longer follow up are necessary to determine if R-ISS is a good risk stratification model to applicate to NDMM pts submitted to aHSCT in the era of novel agents. Disclosures No relevant conflicts of interest to declare.

Abstract The adage for smoldering myeloma (SMM) has been to observe without treatment, until criteria for active multiple myeloma were satisfied. Definitions and risk stratification models have become more sophisticated, with prognostication tailored to include high-risk cytogenetics as per the most recent International Myeloma Working Group 2020 risk model. Moreover, progress in defining genomic evolution and changes in the bone marrow microenvironment through the monoclonal continuum have given insight into the complexities underlying the different patterns of progression observed in SMM. Given recent data showing improved progression-free survival with early intervention in high-risk SMM, the current dilemma is focused on how these patients should be treated. This case-based article maps the significant advancements made in the diagnosis and risk stratification of SMM. Data from landmark clinical trials will also be discussed, and ongoing trials are summarized. Ultimately, we outline our approach to SMM and hope to impart to the reader a sound concept of the current clinical management of SMM.

Background The risk-stratification systems are repeatedly updated in accordance with the emergence of new information about the prognostic impact of anomalies and other factors. The most extensive and modern system in this time is mSMART risk stratification involving many parameters such as genetic anomalies, albumin, beta-2-microglobulin, LDH, Plasma Cell S-phase and GEP levels. It is possible to use risk-adapted treatment programs with or without ASCT. Nevertheless, the role of complex karyotype, combination of genetic abnormalities and ASCT remains unclear. Aims To estimate the genetic abnormalities in patients with newly diagnosed multiple myeloma and define the role of risk-stratification and ASCT in prognosis of disease. Methods The study included 159 patients (median age 63 years, range 28 - 83; male: female ratio - 1:1.37) with NDMM. Metaphase cytogenetics on bone marrow samples was done by standard GTG-method. FISH analyses were performed according to the manufacturer's protocol for detection primary IgH translocations, 13q (13q14/13q34) deletion, 1p32/1q21 amplification/deletion, P53/cen 17 deletion (MetaSystems DNA probes). We additional searched the t(4;14), t(6;14), t(11;14), t(14;16) and t(14;20) in patients with IgH translocation. All patient was treated by bortezomib-based programs (VD, CVD, VMP, PAD). ASCT was performed at 42% patients. Results The frequency of genetic abnormalities in NDMM patients was 49% (78/159). IgH translocation was detected in 26.4% (42/159) patients: t(11;14) - 16.3% (26/159), t(4;14) - 5.0% (8/159); TP53/del17p - 5.6% (9/159); 1p32/1q21 amp/del - 12% (19/159); hypodiploidy - 3.1% (5/159); hyperdiploidy - 1.25% (2/159); del5q - 0,6% (1/159); other - not found. Combination two aberrations was discovered in 11.9% (19/159) patients, complex abnormalities (>3 aberrations) - in 4.4% (7/159) patients. The median OS in "two aberration" and "complex abnormalities" groups were lower than in standard-risk mSMART 3.0 (normal, t(11;14), hypodiploidy, hyperdiploidy and other): 49 months, 26 months and was not reached, respectively (p=.00015). The median PFS for these groups was 12 months, 11 months and 30 months, respectively (p=.011). Differences between "two aberration" and "complex abnormalities" groups were not find (p> .05). We modified high-risk (gain 1q, p53 mutation, del 17p deletion, t(4;14), t(14;16), t(14;20), R-ISS stage III, double and triple hit myeloma) mSMART 3.0 by adding "two aberration" and "complex abnormalities" groups on based the OS and PFS results. The final analysis was based on the results of the complex examination of 87 patients: 53 patients in standard-risk group and 34 patients in high-risk group. The median OS in standard-risk mSMART 3.0 was not reached, in high-risk mSMART 3.0mod - 48 months; 5-years OS was 62% and 38%, respectively (p=0.0073). The median PFS was 43 and 29 months, respectively (p=.09). The best results of OS and PFS were reach in both groups of patient who performed ASCT. The median OS in standard-risk mSMART 3.0 with ASCT (n=37) was not reached, in high-risk mSMART 3.0mod with ASCT - 48 months (n=20); standard-risk mSMART 3.0 without ASCT - 40 months (n=16); in high-risk mSMART 3.0mod without ASCT - 22 months (n=14); 5-years OS was 81%, 60%, 33% and 28%, respectively (p=0.0015). The median PFS was not reached, 46, 22 and 19 months, respectively (p=.017). Conclusions The combination of two aberrations and complex abnormalities is unfavorable prognostic markers. The median OS and PFS was higher in standard-risk than high-risk group according mSMART 3.0mod. The ASCT can improve treatment's outcomes and life expectancy especially in patients with high-risk. It can be useful for update risk stratification in a future. Disclosures Shuvaev: Novartis: Consultancy; Pfize: Honoraria; Fusion Pharma: Consultancy; BMS: Consultancy.

Abstract Background Smoldering multiple myeloma (SMM) is an asymptomatic precursor condition to multiple myeloma (MM). Emerging data from clinical trials indicate that - compared to watchful monitoring - initiation of therapy at the SMM stage might be indicated. Currently, there is no established screening for SMM in the general population and therefore patients are identified incidentally. Here, we define for the first time, epidemiological and clinical characteristics of SMM in the general population based on a large (N&gt;75,000) population-based screening study. Methods The iStopMM study (Iceland Screens Treats or Prevents Multiple Myeloma) is a nationwide screening study for MM precursors where all residents in Iceland over 40 years of age and older were invited to participate. Participants with a positive M-protein on serum protein electrophoresis (SPEP) or an abnormal free light chain (FLC) analysis entered a randomized controlled trial with three arms. Participants in arm 1 continued care in the Icelandic healthcare system as though they had never been screened. Arms 2 and 3 were evaluated at the study clinic with arm 2 receiving care according to current guidelines. In arm 3 bone marrow testing and whole-body low-dose CT (WBLDCT) was offered to all participants. SMM was defined as 10-60% bone marrow plasma cells on smear or trephine biopsy and/or M-protein in serum ≥3 g/dL, in the absence of myeloma defining events. Participants in arm 3 were used to estimate the prevalence of SMM as bone marrow biopsy was performed in all participants of that arm when possible. The age- and sex-specific prevalence was determined with a fitted function of age and sex, and interaction between those. Diagnosis at baseline evaluation of the individuals in the study was used to define the point prevalence of SMM. Results Of the 148,704 individuals over 40 years of age in Iceland, 75,422 (51%) were screened for M-protein and abnormal free light chain ratio. The 3,725 with abnormal screening were randomized to one of the three arms, and bone marrow sampling was performed in 1,503 individuals. A total of 180 patients were diagnosed with SMM, of which 109 (61%) were male and the median age was 70 years (range 44-92). Of those, a total of 157 (87%) patients had a detectable M-protein at the time of SMM diagnosis with a mean M-protein of 0.66 g/dL (range 0.01-3.5). The most common isotype was IgG in 101 (56%) of the patients, 44 (24%) had IgA, 2 (1%) had IgM, and 5 (3%) had biclonal M-proteins. A total of 24 (13%) patients had light-chain SMM. Four patients (2%) had a negative SPEP and normal FLC analysis at the time of SMM diagnosis despite abnormal results at screening. A total of 131 (73%) patients had 11-20% bone marrow plasma cells at SMM diagnosis, 32 (18%) had 21-30%, 9 (5%) had 31-40%, and 8 (4%) had 41-50%. Bone disease was excluded with imaging in 167 (93%) patients (MRI in 25 patients, WBLDCT in 113 patients, skeletal survey in 27 patients, FDG-PET/CT in 1 patient), 13 patients did not have bone imaging performed because of patient refusal, comorbidities, or death. According to the proposed 2/20/20 risk stratification model for SMM, 116 (64%) patients were low-risk, 47 (26%) intermediate-risk, and 17 (10%) high-risk. A total of 44 (24%) had immunoparesis at diagnosis. Using the PETHEMA SMM risk criteria on the 73 patients who underwent testing with flow cytometry of the bone marrow aspirates; 39 (53%) patients were low-risk, 21 (29%) patients were intermediate-risk, and 13 (18%) patients were high-risk. Out of the 1,279 patients randomized to arm 3, bone marrow sampling was performed in 970, and 105 were diagnosed with SMM (10.8%). The prevalence of SMM in the total population was estimated to be 0.53% (95% CI: 0.49-0.57%) in individuals 40 years of age or older. In men and women, the prevalence of SMM was 0.70% (95% CI: 0.64-0.75%) and 0.37% (95% CI: 0.32-0.41%), respectively, and it increased with age in both sexes (Figure). Summary and Conclusions Based on a large (N&gt;75,000) population-based screening study we show, for the first time, that the prevalence of SMM is 0.5% in persons 40 years or older. According to current risk stratification models, approximately one third of patients have an intermediate or high risk of progression to MM. The high prevalence of SMM has implications for future treatment policies in MM as treatment initiation at the SMM stage is likely to be included in guidelines soon and underlines the necessity for accurate risk stratification in SMM.

Abstract Abstract 3056 Introduction: Multiple myeloma (MM) is clinically heterogeneous and risk stratification is vital for prognostication and informing treatment decisions. As bortezomib is able to overcome several adverse features of MM, it has been incorporated into the induction algorithms of high-risk MM. We evaluate the survival data of MM patients managed in a single institution, overall, and with respect to treatment eras before (era 1) and after (era 2) the incorporation of bortezomib as frontline therapy for high-risk MM. Methods: From a comprehensive MM registry maintained in a tertiary institution, we study the survival data of 304 consecutive and previously untreated MM patients managed at our institution from 2000 to 2009. For induction therapy, transplant-eligible patients received. VAD chemotherapy from 2000 to 2004, and thalidomide/dexamethasone (thal/dex) combination from 2004 to 2009. Transplant-ineligible patients received VAD chemotherapy, thal/dex or melphalan/prednisolone (MP) combination from 2001 to 2004, and thal/dex or MP/thalidomide combination from 2004 to 2009. Patients < 65 years were eligible for high-dose therapy with autologous stem cell transplant (HDT/ASCT). Bortezomib became available for treatment of relapsed disease from 2004 and was incorporated into induction therapy in selected patients with high-risk MM from 2006. High-risk MM is defined by presence any adverse factors including stage III on the International Staging System (ISS), deletion 13, hypodiploidy, pseudo-diploidy or near-tetraploidy on metaphase karyotyping, or presence of deletion 17p, t(4;14) or t(14;16) on interphase florescence in-situ hybridization (FISH). As FISH was only available from 2004, the results of FISH will not be included in the survival analysis. Patient and disease characteristics, and survival data were evaluated overall, and with respect to treatment eras. Disease response was assessed by the IMWG criteria after induction treatment and after HDT/ASCT for transplant ineligible and eligible patients respectively. We applied multivariate Cox's regression modeling to determine what baseline parameters, along with the eventual induction response, significantly affected the OS in the respective eras. Results: The median age of all patients was 62 years. Overall, 35%, 40% and 25% of patients presented with ISS stages I, II and III respectively. Conventional karyotyping detected abnormalities in 49% (del 13 [17%], hypodiploidy [18%], hyperdiploidy [22%], pseudodiploidy [7%] and near tetradiploidy [2%]) of patients. Overall, the ISS, conventional cytogenetics, age (≤ or > 60 years), the presenting platelet count (≤ or > 140 × 109/L) and the induction response attained were discriminating of the overall survival (OS) (median= 5.2 yrs) on univariate analyses. Patients and disease characteristic and number of patients undergoing HDT/ASCT were comparable between the 2 eras. 33% of patients in era 1(N=182) were exposed to bortezomib predominantly in the relapse setting, while 52% (41% upfront, 59% during relapse) of patients were exposed to bortezomib (N=123) in era 2. Number of patients attaining ≥ very good partial response (VGPR) were significantly higher in era 2 compared with era 1 (48% vs 26%, p<0.001). The median OS of patients in era 1 and 2 were 5.1 and 6.0 respectively (P=0.06). On multivariate analysis stratified by era, the presence of an abnormal non-hyperdiploid karyotype was the most significant prognostic factor in predicting a worse outcome in era 1(median OS 2.7 years, hazard ratio 3.4, p=0.02), while the attainment of ≥VGPR emerged as the single most significant factor in predicting a favorable outcome in era 2 (median OS 8.1 years, hazard ratio 0.01, p<0.001). Conclusion: Our study suggests that bortezomib use in the frontline, rather than relapse setting may be better able to overcome the effects of adverse cytogenetics. Superseding the adverse effects of all other presenting clinical and laboratory parameters, the attainment of ≥VGPR emerged as the single most significant predictor of long-term survival in the era of novel therapy.

8044 Background: Racial disparities of FISH abnormalities in multiple myeloma (MM) have been well described in whites (W) but partially described in minorities (M) (Paulus et al, ASH 2016, 4432). We aimed to explore racial-based differences of FISH abnormalities using the largest cohort of m to date. Methods: CD-138 selected FISH was done on 799 consecutive patients (pts). Pts without symptomatic MM, and biopsy >6 months after diagnosis were excluded. The abnormalities evaluated included standard and intermediate risk: IGH rearrangements (IGH r), t(4;14), t(11;14), and high risk: t(14;20), t(14;16), del13q, del 17p, 1q21. Chi-square was used for statistical analysis. Due to smaller numbers, all m (Hispanic (H), Black (B), Asian (A) and Other (O)) were included into the same group for statistical analysis. Results: 482 pts were eligible, 343 (71%) were W, 52 (10%) H, 50 (10%) B, 19 (3%) A, and 18 (3%) O. Median age was 65 years, 54% were male, and 26% ISS stage 3. There were no were no statistically significant differences in FISH abnormalities between the m (Table1). Overall W had more abnormalities in IGH r, t(4;14), t(11;14), t(14:20), 1q21 gain compared to M. Most notably W had more IGH r (39% vs 28%; p=0.019) and t(11;14) (20% vs 12%; p=0.024). There were no statistically significant differences between W and m in the high risk FISH abnormalities. Conclusions: We had significant differences in FISH compared to M. W had more IGH r and t(11;14) than M, and there was no difference in high risk FISH abnormalities between W and M. This study confirms the biological racial disparities that exist in minorities with MM. Further studies with more inclusion of minorities are needed to elucidate these disparities and its effects on risk stratification and outcomes. [Table: see text]

Multiple myeloma patients? survival under treatment varies from a few months to more than 15 years. Clinical prognostic factors, especially beta2-microglobulin (B2M) and the international staging system (ISS), allow risk assessment to a certain extent, but do not identify patients at very high risk. As malignant plasma cells are characterized by a variety of chromosomal aberrations and changes in gene expression, a molecular characterization of CD138-purified myeloma cells by interphase fluorescence in situ hybridization (iFISH) and gene expression profiling (GEP) can be used for improved risk assessment. iFISH allows a risk stratification with presence of a translocation t(4;14) and/or deletion of 17p13 being the best documented adverse prognostic factors. A deletion of 13q14 is no longer considered to define adverse risk. Patients harbouring a t(4;14) seems to benefit from a bortezomib- or lenalidomide containing regimen, whereas patients with deletion 17p13 seem only to benefit from a high dose therapy approach using long term bortezomib (in induction and maintenance) and autologous tandem-transplantation as used in the GMMG-HD4 trial, or the total therapy 3 concept. Gene expression profiling allows the assessment of high risk scores (IFM, UAMS), remaining prognostic despite treatment with novel agents, and prognostic surrogates of biological factors (e.g. proliferation) and (prognostic) target gene expression (e.g. Aurora-kinase A). Thus, assessment of B2M and ISS-stage, iFISH, and GEP is considered extended routine diagnostics in therapy requiring multiple myeloma patients for risk assessment and, even now, to a certain extent selection of treatment.

Background: To study the epidemiology, incidence and the clinical outcome of multiple myeloma (MM) among the patients based on the cytogenetic risk stratification.Methods: Author retrospectively analysed 50 patients of Multiple Myeloma (MM) with conventional cytogenetics and interphase Fluorescence In-Situ Hybridization (FISH) method and author classified the risk on the mSMART classification. Treatment and outcome were evaluated separately based on the cytogenetic risk stratification for three arms of treatment- Bortezomib, Thalidomide and Dexamethasone (BTD), Thalidomide and Dexamethasone (TD) and Lenalidomide and Dexamethasone (LD).Results: The median age of the patients was 61years (48-74years) and ratio between male to female was 1.5:1. The overall response (OR) rate among high risk patients treated with Bortezomib, Thalidomide and Dexamethasone (BTD) was 100% with Complete Response (CR) being 26.7%. The OR rate and CR rates among standard risk treated with Thalidomide and Dexamethasone (TD) and Lenalidomide and Dexamethasone (LD) were 61%, 11% and 76%, 18% respectively. The two years overall survival (OS) was 53.3% in high risk and 66.7% with Thalidomide and Dexamethasone (TD) and 76.5% with Lenalidomide and Dexamethasone (LD) in low risk group.Conclusions: The present study showed that the high-risk features of cytogenetics portend poor outcome among MM patients. Bortezomib, Thalidomide and Dexamethasone (BTD) based therapy have improved the Overall Response (OR) rate and Complete Response (CR) rates in high risk MM, however overall survival (OS) is poor in this risk strata. The study also showed that cytogenetic risk stratification and the outcome of myeloma do correlated with each other.

Ultra High Risk

Key Points FLCr ≥100 and BMPC ≥60% identify high-risk SMM, although with more modest median TTP and 2-year PD than previously published. Baseline immunoparesis, eMP, eHb, and edFLC can help identify an ultra-high-risk SMM cohort.
