Abstract Purpose: Multiple myeloma (MM) is a clinically and biologically heterogeneous malignancy of plasma cell. The overall survival of MM patients varies from people to people ranged from several months to decades. It is always knotty how to predict MM prognosis. The presence of circulating plasma cells (CPCs) has been associated with a worse prognosis in patients with MM.Materials and Methods: This study retrospectively analyzed CPCs in 108 cases of newly diagnosed MM patients with 8-color flow cytometry to investigate its value for outcome prediction, and combined CPCs with R-ISS to stratify the risk of MM. Results: CPCs were detected in 58/108 patients (53.7%). The optimum cutoff predicting for overall survival was determined as 0.105% by using a ROC analysis. Compared with patients with CPCs < 0.105% (n = 66,61.1%), those with CPCs ≥0.105% (n = 42, 38.9%) showed lower blood platelet count (BPC) (P=0.038), but higher β2-microglobulin (β2-MG), lactate dehydrogenase (LDH), ferritin (FER) , and harboring P53 deletion, high-risk cytogenetic abnormality, (P = 0.011, 0.001, 0.002, <0.001, and 0.020, respectively). The higher R-ISS stage seems to harbor higher CPCs. CPCs≥0.105% are independently factor for adverse outcome (P<0.001). The combination of R-ISS staging system and CPCs level was used to stratify the risk of multiple myeloma,and R-ISS III stage with CPCs ≥0.105% was ranked as a real ultra-high-risk group. Conclusion: This study suggests that high CPCs is associated with an aggressive disease and that the current R-ISS system in conjunction with CPCs may facilitate the differentiation of NDMM patients. There may also is the potential significance in modifying the definitions of high-risk disease and the practice of adopting a risk-adapted initial treatment.

Background: To investigate the prognostic value of circulating plasma cells (CPC) and establish novel nomograms to predict individual progression-free survival (PFS) as well as overall survival (OS) of patients with newly diagnosed multiple myeloma (NDMM).Methods: One hundred ninetyone NDMM patients in Wuhan Union Hospital from 2017.10 to 2020.8 were included in the study. The entire cohort was randomly divided into a training (n = 130) and a validation cohort (n = 61). Univariate and multivariate analyses were performed on the training cohort to establish nomograms for the prediction of survival outcomes, and the nomograms were validated by calibration curves.Results: When the cut-off value was 0.038%, CPC could well distinguish patients with higher tumor burden and lower response rates (P &lt; 0.05), and could be used as an independent predictor of PFS and OS. Nomograms predicting PFS and OS were developed according to CPC, lactate dehydrogenase (LDH) and creatinine. The C-index and the area under receiver operating characteristic curves (AUC) of the nomograms showed excellent individually predictive effects in training cohort, validation cohort or entire cohort. Patients with total points of the nomograms ≤ 60.7 for PFS and 75.8 for OS could be defined as low-risk group and the remaining as high-risk group. The 2-year PFS and OS rates of patients in low-risk group was significantly higher than those in high-risk group (p &lt; 0.001).Conclusions: CPC is an independent prognostic factor for NDMM patients. The proposed nomograms could provide individualized PFS and OS prediction and risk stratification.

Multiple myeloma (MM) is biologically diverse and there is a significant variation in survival time from a few months to several years. The presence of circulating plasma cells (CPCs) is associated with a worse prognosis in patients with MM. This study retrospectively analyzed CPCs by 8-color multi-parameter flow cytometry in 108 cases of newly diagnosed MM patients to investigate its value for outcome prediction. Among them, 58 (53.7%) patients were CPCs positive expression. The optimum cutoff predicting for overall survival was determined as 0.29% by using a ROC analysis. Compared with patients with CPCs < 0.29% (n = 75, 69.4%), those with CPCs ≥0.29% (n = 33, 30.6%) showed lower Erythrocyte sedimentation rate(ESR) (P = 0.0032), but higher lactate dehydrogenase (LDH), ferritin (FER) , BM PCs and P53 deletion in BM by FISH (P = 0.001, 0.003, 0.014, and 0.001,respectively). With the median follow-up time 17 months (range, 2.0-37.0), the median PFS in the subgroups with CPCs<0.29% and ≥0.29% was not reached and17.0 months (95% confidence interval (CI):14.85-19.15), respectively, and the median OS was not reached and 12.5months (95% CI: 6.35-18.65), respectively. On multivariate analysis for OS, factors independently predictive of mortality were CPCs≥0.29% (hazard ratio (HR) 4.172; 95% CI, 1.61-10.79; P=0.003), Deletion P53(HR 11.54; 95% CI, 4.06-32.84; P<0.001). We further developed a convenient two-factor risk stratification based on CPCs and p53 deletion according to the results of log-rank test, univariate and multivariate analysis. The high-risk group was defined as both CPCs ≥ 0.29% and P53 deletion, accounting for 10% of the population, have a dire prognosis (median PFS = 5 months; OS = 10 months) despite modern therapies .These results identified CPCs as an unfavorable prediction for the outcome of MM. A combination of p53 deletion may screen out a high-risk subgroup which should be considered for novel therapeutic approaches. Disclosures No relevant conflicts of interest to declare.

Abstract Abstract 781 Aim of the present study was to evaluate the impact of bortezomib-based induction treatments on clinical outcomes of newly diagnosed multiple myeloma (MM) patients with unfavorable cytogenetic abnormalities. For this purpose, we analyzed 590 bortezomib-treated patients who were screened at diagnosis for the presence of del(13q), t(4;14) and del(17p) by fluorescence in situ hybridization (FISH) on highly purified bone marrow plasma cells. Patients were stratified into the following 3 groups based on 1) the absence of any cytogenetic abnormality (n=261, or 44%) or 2) the presence of del(13q) alone (n=175, or 30%) or 3) positivity for t(4;14) and/or del(17p) (n=154, or 26%). In the great majority of the patients, loss of 17p was detected in more than 70% of bone marrow plasma cells, a finding which precluded a comparison with patients carrying del(17p) in a lower percentage of plasma cells. After diagnosis, 218 patients received induction therapy with bortezomib-thalidomide-dexamethasone (VTD), while the remaining 372 patients were treated with bortezomib-melphalan-prednisone (VMP) (n=181) or VMP plus thalidomide (VMPT) (n=191). The median number of bortezomib infusions (1.3 mg/m2) actually received was 24. Baseline characteristics of the 3 groups of patients were comparable, with the exception of a higher frequency of ISS stage 3 among patients with t(4;14) and/or del(17p) as compared with the cytogenetic-negative group (29% vs 17%, respectively; p=0.003). The rates of absence or presence of del (13q), t(4;14) and/or del(17p) were comparable among patients receiving VTD or VMP or VMPT treatments. Best CR to overall treatment protocols was 39% for the cytogenetic-negative group and 44% for high-risk patients carrying t(4;14) and/or del(17p). With a median follow-up of 27.5 months, median PFS was 40.5 months for patients without cytogenetic abnormalities as compared with 34 months for the high-risk group (p=0.7), while it was not reached after 38 months in the group with del(13q) alone (p not statistically significant for comparison with the other two groups). Overall, the frequency of events was 31% for patients without cytogenetic abnormalities or with del(13q) alone in comparison with 38% for those with high-risk cytogenetic profiles (p=0.15). Median OS was not reached in any of the 3 groups. Forty-month projected OS rates were 89% for the cytogenetic-negative group, 81% for the group with del(13q) alone (p=0.6) and 77% for the high-risk group (p=0.003 for comparison between this latter and the cytogenetic-negative group). Patients with t(4;14) and/or del(17p) had a shorter OS after relapse in comparison with the cytogenetic-negative group (20-month projected rates: 60% vs 76%, respectively; p=0.01). To more carefully evaluate the prognostic relevance of high-risk cytogenetic abnormalities, we stratified patients in the high-risk group into the following 3 subgroups: 1) t(4;14)-positive but del(17p)-negative (84 patients); 2) del(17p)-positive in the absence of t(4;14) (54 patients); t(4;14)-positive and del(17p)-positive (16 patients). Median PFS was not reached after 40 months for patients with t(4;14) alone, while it was 33 months for patients with del(17p) alone (p=0.1) and was 18.5 months for those who carried both these abnormalities (p=0.0008 for comparison between these latter patients and t(4;14)-positive patients). Overall, the frequency of events was 30% and 41% for patients carrying either t(4;14) or del(17p), respectively (p=0.13), while it was as high as 69% for patients with both these abnormalities. The 40-month projected OS rates for these 3 subgroups were 79%, 82% and 64%, respectively (p not significant). In conclusion, the present analysis of a large series of newly diagnosed MM patients receiving bortezomib-based induction treatments showed that: 1) del(13q) alone had no adverse effect on both PFS and OS; 2) the presence of t(4;14) and/or del(17p) did not adversely influence PFS, but was associated with a shorter OS, due at least in part to a worse outcome after relapse; 3) in comparison with t(4;14), del(17p) alone did not predicted for shorter PFS and OS, possibly as a result of the relatively long-term exposure to bortezomib); 4) the presence of both del(17p) and t(4;14) was likely to confer a particularly dismal clinical outlook, a finding which needs to be confirmed in larger series of patients.

Background and aims. Multiple myeloma is a frequent hematologic malignancy, in which the International Stratification Score (ISS) is widely used to estimate the overall survival. However, there are no studies in Latin America evaluating its performance. This study aims to describe the ISS performance in the overall survival estimation for newly diagnosed multiple myeloma patients in Uruguay. Methods. This is a retrospective registry‐based survival analysis through the Grupo Uruguayo de Mieloma Múltiple (GUMMA) database, including newly diagnosed multiple myeloma patients from January 2001 until May 2019. Results. 249 patients were included, 51.81% males and an average age of 63.49 years. According to ISS and Durie-Salmon score (DSS), 47.79% and 82.3% were ISS III and DSS III, respectively. Also, 32.3% were DSS B. Auto hematopoietic stem cell transplantation was performed in 31.73% of patients, and bortezomib was used in 44.18% as frontline therapy. The overall survival was 80% for ISS1, 64.9% ISS2, and 48.6% ISS3 (Log-Rank; p <0.01). The average overall survival was 116.5 months for ISS 1, 77.6 months for ISS 2, and 57.8 months for ISS 3. The hazard ratio between ISS II and ISS I was 2.42 (95% CI 1.10-5.33; p<0.05), and 3.94 (95% CI 1.88-8.26; p<0.05) between ISS III and ISS II. Conclusion. The ISS staging system allows an adequate stratification of patients according to overall survival in the real-practice setting. However, considering the relevance of the new cytogenetic advances, it is necessary to increase the availability and quality of iFISH in Latin America.

Abstract The purpose of this study was to quantitate the number and labeling index of monoclonal plasma cells in the blood of patients with newly diagnosed multiple myeloma (MM) to learn if these values were independent prognostic factors for survival. Patients were candidates for this study if they had untreated myeloma requiring therapy, were evaluated at our institution between 1984 and 1993, and had a sample of blood analyzed with a sensitive immunofluorescence technique for monoclonal plasma cells and the blood B-cell labelling index (BLI). The % blood monoclonal plasma cells (%BPC) and the BLI were analyzed along with stage, marrow plasma cell LI, % marrow plasma cells, calcium, creatinine, albumin, beta-2-microglobulin, and C-reactive protein as univariate and multivariate factors for survival. Eighty percent of the 254 patients accrued to this study had monoclonal BPC detected. The median % BPC was 6% and 57% (144 of 254) of patients had a high number (> or = 4%). Patients with > or = 4% BPC had a median survival of 2.4 years vs 4.4 years for those with < 4% BPC (P < .001). The BLI was also prognostic (P = .008). In a multivariate analysis, the % BPC, age, albumin, stage, marrow plasma cell LI, and the BLI were independent factors for survival. The %BPC and the marrow plasma cell LI best separated the group into low, intermediate, and high risk myeloma with median survivals of 52, 35, and 26 months, respectively. Patients with high %BPC were less likely to have lytic bone disease from their MM (P = .002). The %BPC and the BLI are independent prognostic factors for survival and are useful in identifying patients as low, intermediate, and high risk. Clonal cells in the blood should be quantified in future clinical trials for myeloma.

Abstract Abstract 2965 The cyclin-D1 proto-oncogene is an important cell regulator of G1 to S phase progression. The overexpression of cyclin-D1 has been linked to the development and progression of several malignancies. The aim of our study was to evaluate the impact of the immunohistochemical expression of cyclin-D1on the plasma cells of trephine biopsies on survival of newly-diagnosed patients with multiple myeloma (MM) who were treated with novel agents. We evaluated formalin-fixed, paraffin-embedded, bone marrow sections of 130 consecutive patients with newly-diagnosed MM (67M/63F; median age 68 years) before any kind of therapy administration. One hundred and fifteen patients had symptomatic disease that required therapy: 29 (25%) received bortezomib-based regimens and 31 (26%) received thalidomide-based regimens as first line therapy, while all patients received regimens containing bortezomib or an IMiD at some point during the course of their disease. Immunohistochemistry was performed in all trephine biopsies using monoclonal antibodies against cyclin-D1 (Cell Marque Corp., Rocklin, CA, USA), but also against CD56 (Cell Marque Corp., Rocklin, CA, USA), CD27 (Novocastra, Newcastle upon Tyne, UK), CD117 and MUM-1 (DAKO A/S, Glostrup, Denmark), as recommended by the manufacturers. A case was considered positive if there was unequivocal positive staining of at least 20% of the plasma cells for cyclin-D1, CD56 and MUM-1 and a positive staining of at least 10% of the plasma cells for CD117 and CD27. Among patients with symptomatic myeloma (N=115), positive staining for cyclin-D1 was found in 35 (30%) patients, for CD56 in 45 (39%), for CD117 in 94 (81%) and for CD27 in 72 (62%) patients. In patients with asymptomatic myeloma, positive staining for Cyclin-D1 was found only in 1 (7%) patient, for CD56 in 9 (64%), and for CD117 in 6 (43%) (p<0.01 for all comparisons compared to symptomatic patients). There were significant positive correlations between positivity for CD27 and CD56 (p<0.001), between positivity for cyclin-D1 and CD117 (p=0.045) and a negative correlation between positivity for CD117 and CD56 (p=0.001). We also observed significant correlations between CD56 positivity and ISS-1 or ISS-2 (p=0.01) and between CD117 positivity and ISS-3 disease (p=0.002). The median overall survival (OS) for patients with symptomatic MM was 57 months (range 22–120 months). In the univariate analysis, positivity for cyclin-D1 (41 vs. 62 months, p=0.03) and for CD117 (50 vs. 75 months p=0.018) were associated with inferior survival, while positivity for CD56 (47 vs. 62 months, p=0.286), MUM-1 (52.7 vs. 63.8 months, p=0.528) and CD27 (57 vs. 50 months, p=0.445) were not. Other factors associated with inferior OS, in the univariate analysis, included ISS-3 (median OS 37 months, vs. 57 months for ISS-2 and 73 months for ISS-1, p=0.005), Hb <10 g/dl (56 vs. 73 months, p=0.044), corrected serum calcium >11.5 g/dl (29 vs. 62 months, p=0.02), serum LDH above upper normal limit (31 vs. 61 months, p=0.05), serum creatinine >2 mg/dl (26 vs. 64 months, p=0.007), low platelet counts (<100,000/ml) (22 vs. 62 months, p=0.031) and age >65 years (45 months vs. not reached for younger patients, p=0.002). In the multivariate analysis, positivity for cyclin-D1 (HR: 2.6; p=0.001), ISS stage (HR: 1.8; p=0.001) and age >65 (HR 2.7, p=0.003) were independently associated with inferior survival. Immunohistochemistry for cyclin-D1 identified subgroups of patients in ISS-2 and in ISS-3 who had extremely poor outcome. Patients with cyclin-D1 positivity had a median survival of 22 months in ISS-2 (vs. 64 months for the rest of ISS-2 patients, p=0.01) and of 13 months in ISS-3 (vs. 47 months for the rest of ISS-3, p=0.012). Our findings underline that the immunohistochemical expression of cyclin-D1 in the bone marrow trephine biopsies has independent prognostic value in MM patients, even in the era of novel agents. This marker can easily be assessed in patients who undergo a trephine biopsy as part of their initial evaluation and offers significant prognostic information. Furthermore, novel agents targeting cyclin-D1 may be of therapeutic value in MM. Disclosures: No relevant conflicts of interest to declare.

Multiple myeloma is a treatable, but currently incurable, hematological malignancy of plasma cells characterized by diverse and complex tumor genetics for which precision medicine approaches to treatment are lacking. The MMRF CoMMpass study is a longitudinal, observational clinical study of newly diagnosed multiple myeloma patients where tumor samples are characterized using whole genome, exome, and RNA sequencing at diagnosis and progression, and clinical data is collected every three months. Analyses of the baseline cohort identified genes that are the target of recurrent gain- and loss-of-function events. Consensus clustering identified 8 and 12 unique copy number and expression subtypes of myeloma, respectively, identifying high-risk genetic subtypes and elucidating many of the molecular underpinnings of these unique biological groups. Analysis of serial samples showed 25.5% of patients transition to a high-risk expression subtype at progression. We observed robust expression of immunotherapy targets in this subtype, suggesting a potential therapeutic option.

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.

ObjectivesUveal melanoma (UM) is the most common primary intraocular malignancy in adults, and immune infiltration plays a crucial role in the prognosis of UM. This study aimed to generate an immunological marker-based predictive signature for the overall survival (OS) of UM patients.MethodsSingle-sample gene-set enrichment analysis (ssGSEA) was used to profile immune cell infiltration in 79 patients with UM from The Cancer Genome Atlas (TCGA) database. Univariate and multivariate least absolute shrinkage and selection operator (LASSO) Cox regressions were used to determine the prognostic factors for UM and construct the predictive immunosignature. Receiver operating characteristic (ROC) curves, decision curve analysis (DCA), and calibration curves were performed to evaluate the clinical ability and accuracy of the model. In addition, the predictive accuracy was compared between the immunosignature and the Tumor, Node, Metastasis (TNM) staging system of American Joint Committee on Cancer (AJCC). We further analyzed the differences in clinical characteristics, immune infiltrates, immune checkpoints, and therapy sensitivity between high- and low-risk groups characterized by the prognostic model.ResultsHigher levels of immune cell infiltration in UM were related to a lower survival rate. Matrix metallopeptidase 12 (MMP12), TCDD inducible poly (ADP-ribose) polymerase (TIPARP), and leucine rich repeat neuronal 3 (LRRN3) were identified as prognostic signatures, and an immunological marker-based prognostic signature was constructed with good clinical ability and accuracy. The immunosignature was developed with a concordance index (C-index) of 0.881, which is significantly better than that of the TNM staging system (p &lt; 0.001). We further identified 1,762 genes with upregulated expression and 798 genes with downregulated expression in the high-risk group, and the differences between the high- and low-risk groups were mainly in immune-related processes. In addition, the expression of most of the immune checkpoint-relevant and immune activity-relevant genes was significantly higher in the high-risk group, which was more sensitive to therapy.ConclusionWe developed a novel immunosignature constructed by MMP12, TIPARP, and LRRN3 that could effectively predict the OS of UM.

Abstract Purpose: Karyotype at diagnosis provides the most important prognostic information in younger adults with acute myeloid leukemia (AML). However, there are few data available looking in particular at patients (pts.) above 60 years of age. We prospectively analyzed 361 elderly pts. with newly diagnosed AML. All pts. were treated within the AMLHD98B treatment trial and received intensive induction and consolidation therapy. Pts. exhibiting a t(15;17) received an age-adjusted AIDA-regimen. Median follow-up time was 48 months. The median age was 67 years (range 60–85 years). Results: 160 pts. had a normal karyotype (44%); 48 pts. (13%) exhibited the balanced translocations t(8;21) (n=12), inv(16) (n=14), t(15;17) (n=11), or t(11q23) (n=11); in the absence of these balanced translocations, 73 pts. exhibited a single aberration, 179 pts. two aberrations, and 61 pts. a complex karyotype (≥3 aberrations; including 44 pts. with 5 or more aberrations). Analyses were normalized to the complete remission (CR) rate (52%), cumulative incidence of relapse (CIR) (77%) and overall survival (OS) (13%) after 4 years of pts. with normal karyotype. Pts. exhibiting a t(15;17) showed a significantly better CIR (29%) and OS (55%), whereas pts. with the other balanced translocations [t(8;21), inv(16)/t(16;16) and t(11q23)] did not differ from pts. with normal karyotype. The limited backward selected Cox-model for OS [t(15;17) excluded] revealed two risk groups: standard-risk [normal karyotype, t(8;21), inv(16), t(11q23), +8 and +11 in absence of a complex karyoytpe] and high-risk [all other aberrations]. The CR rates were 56% and 18%, and the OS-rates after 4 years for the standard- (n=223) and the high-risk group (n=127) were 15% and 0%, respectively. The MRC risk classification system for patients &gt;55 years applied to our patients revealed CR- and OS-rates after 4 years of 73% and 19%, 47% and 12%, as well as 7% and 0% for the low (n=26), intermediate (n=282) and high risk groups (n=44), respectively [t(15;17) excluded]. In conclusion, our risk classification system identified a large high-risk group (36%) of elderly patients with AML who did not benefit from intensive chemotherapy.
