RESUMO

Despite remarkable advances in the treatment of multiple myeloma in the last decades, the prognosis of patients harboring high-risk cytogenetic abnormalities remains dismal as compared to that of standard-risk patients. Proteasome inhibitors demonstrated to partially ameliorate the prognosis of high-risk patients. We pooled together data from two phase I/II trials on transplant-ineligible patients with multiple myeloma receiving upfront carfilzomib cyclophosphamide and dexamethasone followed by carfilzomib maintenance. The aim of this analysis was to compare treatment outcomes in patients with standard- versus high-risk cytogenetic abnormalities detected by fluorescence in situ hybridization (FISH) analysis. High risk was defined by the presence of at least one chromosomal abnormality, including t(4;14), del17p and t(14;16). Overall, 94 patients were included in the analysis: 57 (61%) in the standard-risk and 37 (39%) in the high-risk group. Median follow-up was 38 months. In standard- vs. high-risk patients, we observed similar progression-free survival (3-year PFS: 52% vs. 43%, respectively; p=0.50), overall survival (3-year OS: 78% vs. 73%; p=0.38), and overall response rate (88% vs 95%; p=0.47), with no statistical differences between the two groups. No difference in terms of progression-free survival was observed between patients with or without del17p. Carfilzomib, used both as induction and maintenance agent for transplant-ineligible newly diagnosed multiple myeloma patients, mitigated the poor prognosis carried by high-risk cytogenetics and resulted into similar progression-free survival and overall survival, as compared to standard-risk patients. ClinicalTrials.gov IDs: NCT01857115 (IST-CAR-561) and NCT01346787 (IST-CAR-506).

RESUMO

Extramedullary disease is relatively frequent in multiple myeloma, but our knowledge on the subject is limited and mainly relies on small case series or single center experiences. Little is known regarding the role of new drugs in this setting. We performed a meta-analysis of eight trials focused on the description of extramedullary disease characteristics, clinical outcome, and response to new drugs. A total of 2,332 newly diagnosed myeloma patients have been included; 267 (11.4%) had extramedullary disease, defined as paraosseous in 243 (10.4%), extramedullary plasmocytoma in 12 (0.5%), and not classified in 12 (0.5%) patients. Median progression-free survival was 25.3 months and 25.2 in extramedullary disease and non-extramedullary disease patients, respectively. In multivariate analysis the presence of extramedullary disease did not impact on progression-free survival (hazard ratio 1.15, P=0.06), while other known prognostic factors retained their significance. Patients treated with immunomodulatory drugs, mainly lenalidomide, or proteasome inhibitors had similar progression-free survival and progression-free survival-2 regardless of extramedullary disease presence. Median overall survival was 63.5 months and 79.9 months (P=0.01) in extramedullary and non-extramedullary disease patients, respectively, and in multivariate analysis the presence of extramedullary disease was associated with a reduced overall survival (hazard ratio 1.41, P<0.001), in line with other prognostic factors. With the limits of the use of low sensitivity imaging techniques, that lead to an underestimation of extramedullary disease, we conclude that in patients treated with new drugs the detrimental effect of extramedullary disease at diagnosis is limited, that lenalidomide is effective as are proteasome inhibitors, and that these patients tend to acquire a more aggressive disease in later stages.

RESUMO

: We conducted a pooled analysis of two phase III trials, RV-MM-EMN-441 and EMN01, to compare maintenance with lenalidomide-prednisone vs. lenalidomide in newly diagnosed transplant-eligible and -ineligible myeloma patients. Primary endpoints were progression-free survival, progression-free survival 2 and overall survival with both regimens. A secondary aim was to evaluate the impact of duration of maintenance on overall survival and on outcome after relapse. A total of 625 patients (lenalidomide-prednisone arm, n = 315; lenalidomide arm, n = 310) were analyzed. The median follow-up was 58 months. Median progression-free survival (25 vs. 19 months; p = 0.08), progression-free survival 2 (56 vs. 49 months; p = 0.9) and overall survival (73 months vs. NR; p = 0.08) were not significantly different between the two arms. Toxicity profiles of lenalidomide-prednisone and lenalidomide were similar, with the exception of neutropenia that was higher in the lenalidomide arm (grade ≥ 3: 9% vs. 19%, p < 0.001), without an increase in the rate of infections. Overall survival (median NR vs. 49 months, p < 0.001), progression-free survival from relapse (median 35 vs. 24 months, p = 0.004) and overall survival from relapse (median not reached vs. 41 months, p = 0.002) were significantly longer in patients continuing maintenance for ≥2 years. We showed that the addition of prednisone at 25 or 50 mg every other day (eod) to lenalidomide maintenance did not induce any significant advantage.

RESUMO

The introduction of new agents and management strategies over the past decade has resulted in a major step change in treatment outcomes with deepening responses and increased survival for patients with multiple myeloma. In daily clinical practice, healthcare professionals are now faced with challenges including, optimal treatment sequencing and changing treatment goals. In light of this, a group of experts met to discuss diagnostic and treatment guidelines, examine current clinical practice, and consider how new clinical trial data may be integrated into the management of multiple myeloma in the future.

RESUMO

PURPOSE: Data collection in clinical trials is becoming complex, with a huge number of variables that need to be recorded, verified, and analyzed to effectively measure clinical outcomes. In this study, we used data warehouse (DW) concepts to achieve this goal. A DW was developed to accommodate data from a large clinical trial, including all the characteristics collected. We present the results related to baseline variables with the following objectives: developing a data quality (DQ) control strategy and improving outcome analysis according to the clinical trial primary end points. METHODS: Data were retrieved from the electronic case reporting forms (eCRFs) of the phase III, multicenter MCL0208 trial (ClinicalTrials.gov identifier: NCT02354313) of the Fondazione Italiana Linfomi for younger patients with untreated mantle cell lymphoma (MCL). The DW was created with a relational database management system. Recommended DQ dimensions were observed to monitor the activity of each site to handle DQ management during patient follow-up. The DQ management was applied to clinically relevant parameters that predicted progression-free survival to assess its impact. RESULTS: The DW encompassed 16 tables, which included 226 variables for 300 patients and 199,500 items of data. The tool allowed cross-comparison analysis and detected some incongruities in eCRFs, prompting queries to clinical centers. This had an impact on clinical end points, as the DQ control strategy was able to improve the prognostic stratification according to single parameters, such as tumor infiltration by flow cytometry, and even using established prognosticators, such as the MCL International Prognostic Index. CONCLUSION: The DW is a powerful tool to organize results from large phase III clinical trials and to effectively improve DQ through the application of effective engineered tools.

RESUMO

In the EMN01 trial, the addition of an alkylator (melphalan or cyclophosphamide) to lenalidomide-steroid induction has been prospectively evaluated in transplant-ineligible multiple myeloma patients. After induction, patients were randomly assigned to maintenance treatment with lenalidomide alone or with prednisone continuously. This analysis (median follow-up of 71 months) focused on maintenance treatment and on subgroup analyses according to the International Myeloma Working Group Frailty Score. 217 patients in lenalidomide-dexamethasone, 217 in melphalan-prednisone-lenalidomide and 220 in cyclophosphamide-prednisone-lenalidomide arms were evaluable. 284 (43%) patients were fit, 205 (31%) intermediate-fit and 165 (25%) frail. After induction, 402 patients were eligible for maintenance, (lenalidomide arm: 204; lenalidomide-prednisone: 198). After a median duration of maintenance of 22.0 months, progression-free survival from start of maintenance was 22.2 months with lenalidomide-prednisone vs 18.6 months with lenalidomide (HR 0.85,p=0.14), with no differences across frailty subgroups. The most frequent grade ≥3 toxicity was neutropenia (10% of lenalidomide-prednisone and 21% of lenalidomide patients; p=0.001). Grade ≥3 non-hematologic adverse events were rare (<15%). In fit patients, melphalan-prednisone-lenalidomide significantly prolonged progression-free survival compared to cyclophosphamide-prednisone-lenalidomide (HR 0.72,p=0.05) and lenalidomide-dexamethasone (HR 0.72, p=0.04). Likewise, a trend towards a better overall survival was noted for melphalan-prednisone-lenalidomide and cyclophosphamide-prednisone-lenalidomide, as compared to lenalidomide-dexamethasone. No differences were observed in intermediate-fit and frail patients. This analysis showed positive outcomes of maintenance with lenalidomide-based regimens, with a good safety profile. For the first time, we showed that fit patients benefit from a triplet full-dose regimen, while intermediate-fit and frail patients from gentler regimens. ClinicalTrials.gov registration number: NCT01093196.

RESUMO

Adoptive cellular therapy using chimeric antigen receptor T-cell (CART) therapy is currently being evaluated in patients with relapsed / refractory multiple myeloma (MM). The majority of CAR-T cell programs now being tested in clinical trials are targeting B-cell maturation antigen. Several recent phase I / II trials show promising preliminary results in patients with MM progressing on proteasome inhibitors, immunomodulatory drugs and monoclonal antibodies targeting CD38. CAR-T cell therapy is a potentially life-threatening strategy that can only be administered in experienced centers. For the moment, CAR-T cell therapy for MM is still experimental, but once this strategy has been approved in relapsed/refractory MM, it will become one of the most important indications for this therapy in Europe and world-wide. This manuscript proposes practical considerations for the use of CAR-T cell therapy in MM, and discusses several important issues for its future development.

RESUMO

In chronic lymphocytic leukemia, the hypoxia-inducible factor 1 (HIF-1) regulates the response of tumour cells to hypoxia and their protective interactions with the leukemic microenvironment. In this study we demonstrate that chronic lymphocytic leukemia cells from TP53-disrupted (TP53dis) patients have constitutively higher expression levels of the α-subunit of HIF-1 (HIF-1 α) and increased HIF-1 transcriptional activity, compared to the wild type counterpart. In the TP53dis subset, HIF-1 α upregulation is due to reduced expression of the HIF-1 α ubiquitin ligase von Hippel-Lindau protein (pVHL). Hypoxia and stromal cells further enhance HIF-1α accumulation, independently from the TP53 status. Hypoxia acts through the downmodulation of pVHL and the activation of the PI3K/AKT and RAS/ERK1-2 pathways, whereas stromal cells induce an increased activity of the RAS/ERK1-2, RHOA/RHOA kinase and PI3K/AKT pathways, without affecting pVHL expression. Interestingly, we observed that higher levels of HIF-1A mRNA correlate with a lower susceptibility of leukemic cells to spontaneous apoptosis, and associate with the fludarabine resistance that mainly characterizes TP53dis tumour cells. The HIF-1α inhibitor BAY87-2243 exerts cytotoxic effects toward leukemic cells, regardless of the TP53 status, and has anti-tumour activity in Eµ-TCL1 mice. BAY87-2243 also overcomes the constitutive fludarabine resistance of TP53dis leukemic cells and elicits a strongly synergistic cytotoxic effect in combination with ibrutinib, thus providing preclinical evidences for its further investigation as a potential new drug in chronic lymphocytic leukemia.

RESUMO

Bortezomib-melphalan-prednisone and continuous lenalidomide-dexamethasone represent the standard treatment of transplant-ineligible, newly diagnosed, multiple myeloma patients. To date, no randomized trial has compared bortezomib-melphalan-prednisone to lenalidomide-dexamethasone, and there is no evidence of the optimal treatment for newly diagnosed multiple myeloma, particularly in high-risk cytogenetic patients (del(17p), t(4;14) or t(14;16)). We pooled together data from newly diagnosed myeloma patients treated with bortezomib-melphalan-prednisone or lenalidomide-dexamethasone induction followed by lenalidomide maintenance 10 mg enrolled in the GIMEMA-MM-03-05 and EMN01 trials, to evaluate their efficacy in different patient subgroups, focusing on standard and high-risk cytogenetics. Overall, 474 patients were analyzed (bortezomib-melphalan-prednisone: 257 patients; lenalidomide-dexamethasone followed by lenalidomide maintenance: 217 patients). No difference in progression-free survival (Hazard Ratio: 0.96) and overall survival (Hazard Ratio: 1.08) was observed between bortezomib-melphalan-prednisone and lenalidomide-dexamethasone followed by lenalidomide in standard-risk, while a reduction in the risk of progression (Hazard Ratio: 0.54) and death (Hazard Ratio: 0.73) was seen in high-risk patients treated with bortezomib-melphalan-prednisone vs. lenalidomide-dexamethasone followed by lenalidomide. In particular, standard risk patients >75years benefited less from bortezomib-melphalan-prednisone than lenalidomide-dexamethasone followed by lenalidomide (Hazard Ratio for progression-free survival: 0.96; Hazard Ratio for overall survival: 1.81). In this non-randomized analysis, bortezomib-melphalan-prednisone and lenalidomide-dexamethasone followed by lenalidomide were equally effective in younger (≤75years), standard-risk patients, while older ones (>75years) benefited more from lenalidomide-dexamethasone followed by lenalidomide. In high-risk patients, bortezomib-melphalan-prednisone improved progression-free survival and overall survival irrespective of age. The source trials are registered at ClinicalTrials.gov (NCT01063179 and NCT01093196).

RESUMO

Cellular therapies are a rapidly evolving approach to treat cancer in the light of their unique mechanism of action that potentially overcomes drug resistance and induces durable remissions. Modalities of adoptive cell therapy include gene-modified T cells expressing novel T cell receptors or chimeric antigen receptors (CAR) that modify the immune system to recognize tumor cells and carry out potent anti-tumor effector functions. CAR T cells have shown very promising clinical results and several trials are being conducted worldwide to establish their role in cancer treatment. Most successful results have been observed in lymphoproliferative disorders with the use of CD19-directed CAR T cells, which led to their commercial approval by FDA. In this review, we provide a comprehensive overview of the current role of CAR T cell therapies in hematological malignancies and solid tumors, their associated toxicities and potential future developments in the armamentarium for cancer treatment.

RESUMO

With the introduction of new drugs with different mechanisms of action, multiple myeloma (MM) patients' outcomes have improved. However, the efficacy seen in clinical trials is often not seen in real-world settings and data on the effectiveness of MM therapies are needed. INSIGHT MM is a prospective, global, non-interventional, observational study that is enrolling approximately 4200 patients with newly diagnosed or relapsed/refractory MM, making it the largest study of its kind to date. The study aims to describe contemporary, real-world patterns of patient characteristics, clinical disease presentation, therapies chosen, clinical outcomes (response, treatment duration, time-to-next-therapy, progression-free and overall survival), safety, healthcare resource utilization and quality of life. One interim analysis has been conducted to date; current accrual is approximately 3094 patients. Trial registration number: NCT02761187.

RESUMO

AIM: This study aimed to report patterns of biosimilar filgrastim prophylaxis and outcomes of chemotherapy-induced neutropenia (CIN)/febrile neutropenia (FN) in patients with hematological malignancies or solid tumors. PATIENTS & METHODS: MONITOR-GCSF is a real-world study of 1447 cancer patients receiving CIN/FN prophylaxis with biosimilar filgrastim (solid tumors: 77.2%; hematological malignancies: 22.8%). RESULTS: Differences in prophylaxis intensity and day of initiation relative to guideline recommendations were observed. In hematology patients, higher rates of CIN and FN occurred at cycle level, and rate of FN was higher at patient level (9.1 vs 5.0% in solid tumor patients). CONCLUSION: Adequate GCSF support in hematology and solid tumor patients is important to prevent CIN/FN and related hospitalizations and chemotherapy disturbances.

RESUMO

Twice-weekly carfilzomib is approved at 27 and 56 mg/m2 to treat relapsed multiple myeloma patients. In the phase III study ARROW, once-weekly 70 mg/m 2 carfilzomib prolonged the median progression-free survival of relapsed multiple myeloma patients in comparison with twice-weekly 27 mg/m2 carfilzomib, without adding significant toxicity. Data were pooled from two phase I/II studies of newly diagnosed multiple myeloma patients who received nine induction cycles of carfilzomib (either 70 mg/m2 once-weekly or 36 mg/m2 twice-weekly), cyclophosphamide and dexamethasone, followed by carfilzomib maintenance. Overall, 121 transplant-ineligible patients with newly diagnosed multiple myeloma were analyzed (once-weekly, n=63; twice-weekly, n=58). We found no significant difference in median progression-free survival [35.7 months (95%CI: 23.7-not reached, NR) vs 35.5 months (95%CI: 24.3-NR); HR: 1.39; P=0.26] and 3-year overall survival [70% [95%CI: 59%-84%) vs 72% (95%CI: 60%-85%); HR: 1.27; P=0.5] between once-weekly and twice-weekly carfilzomib. From the start of maintenance, 3-year progression-free survival [47% (95%CI: 33%-68%) vs 51% (95%CI: 38%-70%); HR: 1.04; P=0.92] and overall survival [72% (95%CI: 58%-89%) vs 73% (95%CI: 59%-90%); HR: 0.82; P=0.71] were similar in the once- versus twice-weekly carfilzomib. The rate of grade 3-5 hematologic (24% vs 30%; P=0.82) and non-hematologic (38% vs 41%; P=0.83) adverse events was similar in the two groups. Once-weekly 70 mg/m2 carfilzomib as induction and maintenance therapy for newly diagnosed multiple myeloma patients was as safe and effective as twice-weekly 36 mg/m2 carfilzomib and provided a more convenient schedule. The trials are registered at clinicaltrials.gov identifiers: 01857115 (IST-CAR-561) and 01346787 (IST-CAR-506).

RESUMO

BACKGROUND: Several new drugs are approved for treatment of patients with multiple myeloma (MM), but no validated biomarkers are available for the prediction of a clinical outcome. We aimed to establish whether pretreatment blood and bone marrow plasma concentrations of major cytokines and angiogenic factors (CAFs) of patients from a phase 3 trial of a MM treatment could have a prognostic and predictive value in terms of response to therapy and progression-free and overall survival and whether these patients could be stratified for their prognosis. METHODS: Blood and bone marrow plasma levels of Ang-2, FGF-2, HGF, VEGF, PDGF-ß, IL-8, TNF-α, TIMP-1, and TIMP-2 were determined at diagnosis in MM patients enrolled in the GIMEMA MM0305 randomized controlled trial by an enzyme-linked immunosorbent assay (ELISA). These levels were correlated both reciprocally and with the type of therapy and patients' characteristics and with a group of non-MM patients as controls. RESULTS: No significant differences were detected between the blood and bone marrow plasma levels of angiogenic cytokines. A cutoff for each CAF was established. The therapeutic response of patients with blood plasma levels of CAFs lower than the cutoff was better than the response of those with higher levels in terms of percentage of responding patients and quality of response. CONCLUSION: FGF-2, HGF, VEGF, and PDGF-ß plasma levels at diagnosis have predictive significance for response to treatment. The stratification of patients based on the levels of CAFs at diagnosis and their variations after therapy is useful to characterize different risk groups concerning outcome and response to therapy. TRIAL REGISTRATION: Clinical trial information can be found at the following link: NCT01063179.

RESUMO

BACKGROUND: Survival of multiple myeloma patients has considerably improved in the last decades thanks to the introduction of many new drugs, including immunomodulatory agents, proteasome inhibitors and, more recently, monoclonal antibodies. METHODS: We analyzed the most recent literature focusing on the clinical and pharmacologic aspects of monoclonal antibody-based therapies in multiple myeloma, including monoclonal antibodies directed against plasma cell antigens, as well as checkpoint blockade therapy directed against immune inhibitory molecules, used as single agents or in combination therapy. RESULTS: Anti-CD38 monoclonal antibodies including daratumumab, isatuximab and MOR202 have shown outstanding results in relapsed and/or refractory multiple myeloma patients. The addition of daratumumab to bortezomib-dexamethasone or lenalidomidedexamethasone substantially improved patients' outcome in this patient population. The anti- SLAMF7 molecule elotuzumab in combination with lenalidomide-dexamethasone showed to be superior to lenalidomide-dexamethasone alone, without adding meaningful toxicity. Checkpoint blockade therapy in combination with immunomodulatory agents produced objective responses in more than 50% of treated patients. However, this combination was also associated with an increase in toxicity and a thorough safety evaluation is currently ongoing. CONCLUSION: Monoclonal antibodies are reshaping the standard of care for multiple myeloma and ongoing trials will help physicians to optimize their use in order to further improve patients' outcome.

RESUMO

PURPOSE: Granulocyte colony-stimulating factors (G-CSFs) are indicated for prophylaxis or management of chemotherapy-induced neutropenia (CIN) and febrile neutropenia (FN). Guidelines recommend G-CSF 24-72 h following chemotherapy; however, some evidence suggests that G-CSF initiated < 24 h may benefit some patients. METHODS: MONITOR-GCSF was a prospective, observational, multicenter, pan-European study of 1447 chemotherapy-treated patients receiving daily biosimilar (standard) filgrastim (Zarzio®/Zarxio®, filgrastim-sndz, Hexal AG, Sandoz Inc.). In this analysis, cycles were classified as same-day, per-guidelines, or late if G-CSF support was initiated < 24 h, 24-72 h, and > 72 h after chemotherapy. Outcomes included occurrence of CIN of any grade (CIN1/4), grade 3 or 4 (CIN3/4), grade 4 (CIN4), or FN: CIN/FN-related hospitalization or CIN/FN-related chemotherapy disturbance. RESULTS: A total of 5930 chemotherapy cycles from 1423 evaluable patients from MONITOR-GCSF had data for day of G-CSF initiation: 795 cycles (13.4%) classified as same-day, 3320 (56.0%) as per-guidelines, and 1815 (30.6%) as late. Groups did not differ as to CIN1/4 and FN episodes, or CIN/FN-related hospitalizations or chemotherapy disturbances. Patients in the same-day and per-guidelines groups had statistically similar odds of not experiencing any outcomes of interest in any given cycle. Patients in the late group had worse odds of experiencing CIN1/4, CIN3/4, and CIN4 episodes in any given cycle. Proportions of patients reporting clinical events of interest were generally similar. CONCLUSIONS: This real-world evidence indicates that CIN/FN prophylaxis initiated with biosimilar filgrastim within 24-72 h post-chemotherapy is effective and safe. Filgrastim administration on the day of chemotherapy may be appropriate in some patients.

RESUMO

Therapeutic re-challenge is currently a debated issue in the field of multiple myeloma (MM), given the recent availability of several new drugs and combinations. However, very few specific evidences are available about bortezomib re-use at first relapse. This multicenter, observational, retrospective study enrolled 134 MM patients with significant response after bortezomib-based frontline regimens and who had received a first salvage treatment containing bortezomib at relapse. The overall response rate was 71%, including 40% partial responses, 24% very good partial responses, and 7% complete responses. Re-treatment was well-tolerated, with no significant new or unexpected toxicities observed. The median duration of second progression-free survival (PFS) was 15 months, while median PFS2 was 55 months. With a median follow-up of 56 months, overall survival was 94 months for the entire series, without significant differences between patients undergoing or not undergoing transplant procedures. This real-life survey indicates that re-treatment including bortezomib as a first salvage therapy could be still considered in MM patients achieving durable response after initial exposure to bortezomib.

RESUMO

BACKGROUND: Minimal residual disease (MRD) is one of the most relevant prognostic factors in patients with multiple myeloma (MM); however, the impact of maintenance therapy on MRD levels remains unclear. Among patients with newly diagnosed MM (NDMM) who received lenalidomide maintenance until they developed disease progression, the role of MRD status as a predictor of progression-free survival (PFS) was evaluated by multiparameter flow cytometry (MFC) and allelic-specific oligonucleotide real-time quantitative polymerase chain reaction (ASO-RQ-PCR) analysis. METHODS: Seventy-three patients with NDMM enrolled in the RV-MM-EMN-441 (clinical trials.gov identifier, NCT01091831) and RV-MM-COOP-0556 (clinicaltrials.gov identifier, NCT01208766; European Myeloma Network EMN02/HO95 MM Trial) phase 3 trials who achieved at least a very good partial response after intensification/consolidation were included. The median patient age was 57 years (interquartile range, 53-61 years), and all patients received lenalidomide maintenance until they developed progression. MRD was evaluated on bone marrow after intensification/consolidation, after 6 courses of maintenance, and every 6 months thereafter until clinical relapse using both ASO-RQ-PCR (sensitivity, 10-5 ) and MFC (sensitivity, from 10-4 to 10-5 ). RESULTS: After intensification/consolidation, 33 of 72 patients (46%) achieved a molecular complete response (m-CR), and 44 of 70 (63%) achieved a flow complete response (flow-CR). Almost 27% of patients who were MRD-positive after consolidation became MRD-negative during maintenance. After a median follow-up of 38 months, PFS was prolonged in patients who achieved negative MRD status during maintenance according to results from both ASO-RQ-PCR analysis (hazard ratio, 0.29; 95% confidence interval, 0.14-0.62; P = .0013) and MFC (hazard ratio, 0.19; 95% confidence interval, 0.09-0.41; P < .001). The impact of negative MRD status on PFS was similar in all subgroups (ASCT and no-ASCT; International Staging System stages I, II, and III; high-risk and standard-risk cytogenetics), and the two techniques were highly correlated. CONCLUSIONS: MRD status is a stronger predictor of PFS than standard risk factors, and lenalidomide maintenance further increases the rate of negative MRD results.
