Abstract
Multiple myeloma (MM) is a malignant plasma cell neoplasm with complex biology and heterogenous course. Interferon regulatory factor 4 (IRF4) transcription factor, important key developmental stages of hematopoiesis, represents an excellent potential therapeutic target. The present work aimed to investigate the expression status of IRF4 in the diagnostic bone marrow biopsy (BMB) cores of MM patients. This prospective study included 62 newly diagnosed MM patients. The expression of IRF4 was assessed in the BMB by immunohistochemistry (IHC). The data were correlated to the patients' clinico-pathological features, response to treatment and survival rates. IRF4 expression was observed in 50% of MM patients (31/62). IRF-4 positive patients were more frequently male patients (P = 0.018), have immunoglobulin heavy chain (IgH) translocations (P = 0.05) and tended to present with a higher platelets count (P = 0.07). Multiple myeloma patients presenting with urine M-protein had worse overall survival (OS) than negative cases (P = 0.012). Normocellular BM aspirate (BMA) was associated with better OS than hypercellular and hypocellular BMA (P = 0.006). Patchy distribution of plasma cells in BMB was associated with better disease-free survival (DFS) while diffuse infiltration had the worst (P = 0.019). Of note, after treatment, MM patients had significantly lower percentage of BMA plasma cells, platelet count, β2 microglobulin and creatinine levels (P = 0.037, < 0.001, 0.022 and 0.026, respectively). Had higher albumin level (P = 0.007), compared to initial investigations. No significant association was found between IRF4 expression and the patients'clinical outcomes. Patterns of plasma cells distribution in BMB, BMA cellularity and urine M-protein are prognostically relevant in MM.

The Importance of FISH Signal Cut-off Value and Copy Number Variation for 1q21 in Newly Diagnosed Multiple Myeloma: Is it Underestimated? CLINICAL LYMPHOMA, MYELOMA & LEUKEMIA 2022; 22:535-544. [PMID: 35292207 DOI: 10.1016/j.clml.2022.01.013] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/22/2021] [Revised: 12/21/2021] [Accepted: 01/20/2022] [Indexed: 11/19/2022]
Abstract
BACKGROUND The cut-off value for gain/amplification of 1q21(1q21+) was 20% according to the recommendations of the European Myeloma Network and there were limited studies concerning less than 20%. Meanwhile, the copy number variation of 1q21+ remains controversial. Our purpose was to evaluate the significance of clone size and copy numbers of 1q21+ in Chinese newly diagnosed multiple myeloma (NDMM). PATIENTS AND METHODS We retrospectively analyzed 161 consecutive NDMM patients who were tested for common cytogenetic abnormalities at diagnosis by fluorescence in-situ hybridization and 5% was set for the threshold for 1q21+ by a comparative study. RESULTS Ninety-six (59.6%) patients were determined for 1q21+ by fluorescence in-situ hybridization including 38 had ≥4 copies. In clone size analyses, the 2-year progression-free survival (PFS) in <5% group was superior in comparison with 5% to 20% (65.2% vs. 47.0%, P = .041) and >20% group (65.2% vs. 37.5%, P < .001), whereas there was no significant difference between the 2 latter groups. Patients with ≥ 4 copies of 1q21 had inferior 2-year PFS compared to patients with 3 copies (23.3% vs. 50.6%, P = .028) and 2 copies (23.3% vs. 65.2%, P < .001). Bortezomib-based treatment might benefit the PFS for patients with 3 copies but could not improve the adverse effect of ≥ 4 copies. 1q21+ was an independent risk factor for inferior PFS and OS in multivariate analysis (P < .001 and P = .028). CONCLUSION Our results demonstrated that 5% was a reliable cut-off value for 1q21+, and 1q21+ was an adverse prognostic factor in NDMM, especially when ≥ 4 copies were present.

Abstract
Beyond MYC rearrangement, Burkitt lymphoma (BL) often presents with additional aberrations. Biopsy touch imprints from 72 children with BL were tested with interphase fluorescence in-situ hybridization (i-FISH) for MYC, BCL2, BCL6, IGH, IGK and IGL rearrangements and copy-number aberrations involving 1q21/1p32, 7cen/7q31, 9cen/9p21, 13q14/13q34 and 17cen/17p13. Diploid status deviations were investigated with chromosome enumeration probes. MYC rearrangement was demonstrated in all cases. Additional aberrations included +1q (21/72:29.2%), +7q (14/72:19.4%), 13q- (14/72:19.4%), 9p-(6/72:8.3%) and hyperdiploidy (6/72:8.3%). Advanced clinical stage IV, +7q and 9p- were associated with shorter overall survival, with stage IV and +7q retaining prognostic significance on multivariate analysis. No relapse or death was reported among the hyperdiploid cases. This i-FISH investigation provides information on the genetic profile of BL and may prove valuable for patients with no karyotype analysis. Demonstration of hyperdiploidy could evolve research on clonal evolution pathways and probably identify a subgroup of children with favorable prognosis.

Abstract
Pleural effusion (PE) is prevalent in unselected "real-life" populations of multiple myeloma (MM). However, its prognostic value on MM is currently elusive. This study aimed to explore the role of PE on MM prognosis and to develop a novel prognostic nomogram for a cohort of Chinese patients with MM. Patients diagnosed with MM form 2000 through 2017 were retrospectively enrolled. PE was evaluated by chest computed tomography (CT) scans. Independent predictors of overall survival (OS) were identified using a multivariable Cox regression model performed on variables selected by the least absolute shrinkage and selection operator (LASSO) algorithm. A nomogram was constructed based on these variables. The concordance index (C-index) and the calibration curve were used to evaluate the predictive performance of the nomogram. Among 861 patients analyzed, 368 patients developed PE. Multivariate cox regression and restricted mean survival time (RMST) analyses revealed that patients with PE experienced worse OS vs. patients without PE. A nomogram predictive of OS was constructed using PE, plasma cell proportion, international staging system (ISS) stage, Charlson comorbidity index (CCI), 1q21 gain, and autologous hematopoietic stem cell transplantation (HSCT). The nomogram showed satisfactory discrimination in the derivation cohort (C-index=0.729) and the validation cohort (C-index=0.684), outperforming the Durie-Salmon (DS) and ISS staging systems. Moreover, the nomogram accurately classified patients into two distinct high- and low-risk groups. PE is frequently encountered in the disease course for MM patients. We derivated and validated a novel nomogram for MM based on PE, outperforming the DS/ISS staging systems.

Gain of 1q21 is an adverse prognostic factor for multiple myeloma patients treated by autologous stem cell transplantation: A multicenter study in China. Cancer Med 2020; 9:7819-7829.

Abstract
Background Autologous stem cell transplantation (ASCT) has been recommended as a standard approach for young multiple myeloma (MM) patients for decades, even in the era of novel agents. Gain of chromosome 1q21 is a common cytogenetic abnormality in MM, while its clinical prognostic value is still controversial. Methods In this multicenter study, we retrospectively analyzed 1q21 gain in 446 newly diagnosed MM patients who received at least one ASCT from three large myeloma centers in China. Results Of the all 446 patients, 1q21 gain was an adverse predictor of progression‐free survival (PFS) (34 vs 56 months, P = .005) and overall survival (OS) (69 vs 100 months, P = .002). Gain of 1q21 was more likely to coexist with t(4;14), t(14;16), and del(13q). Nevertheless, isolated 1q21 gain still exhibited unfavorable effects on PFS (35 vs 66 months, P = .045) and OS (61 vs 100 months, P = .026). The coexistence of 1q21 gain and high‐risk cytogenetics (HRCs) [del(17p), t(4;14),and/or t(14;16)] showed poor prognosis on both PFS and OS, while no additional adverse effect could be identified when compared with HRCs alone. Moreover, when coexisting with t(11;14), patients with 1q21 gain showed a comparable survival to those without 1q21 gain. For patients treated with novel induction regimens followed by ASCT, 1q21 gain also conferred an inferior prognosis. Multivariate analysis further confirmed 1q21 gain could independently predict shorter PFS and OS. Conclusion In conclusion, 1q21 gain is an adverse prognostic factor for MM patients received ASCT.

Abstract
Although therapeutic strategies have been adapted to age and comorbidities of myeloma patients for a long time, all patients currently experiment the same treatment whatever their genomic risk. However, high-risk patients should benefit right now from the most efficient drugs combinations. Herein, we review and discuss how to optimally define risk to adapt treatment and why a modern multiparametric definition of genomic risk is urgently needed. Minimal residual disease status will probably also take a growing place in patient's management, including in treatment adaptation. We also discuss how next-generation sequencing will definitively represent an essential tool to manage risk-based therapeutic strategies. Finally, despite an explosive knowledge of myeloma molecular landscape, targeted therapy perspectives remain poor, with only few exceptions.

Abstract
Analysis of intraclonal heterogeneity has yielded insights into the clonal evolution of hematologic malignancies. We compared the clonal and subclonal compositions of the underlying plasma cell dyscrasia in 544 systemic light chain amyloidosis (PC-AL) patients with 519 patients with monoclonal gammopathy of undetermined significance (MGUS), smoldering multiple myeloma (SMM), or symptomatic MM; ie, PC-non-AL patients). Using interphase fluorescence in situ hybridization, subclones were stringently defined as clone size below two thirds of the largest clone and an absolute difference of ≥30%. Subclones were found less frequently in the PC-AL group, at 199 (36.6%) of 544 as compared with 267 (51.4%) of 519 in the PC-non-AL group (P < .001), and were not associated with the stage of plasma cell dyscrasia in either entity. In both groups, translocation t(11;14), other immunoglobulin heavy chain translocations, and hyperdiploidy were typically found as main clones, whereas gain of 1q21 and deletions of 8p21, 13q14, and 17p13 were frequently found as subclones. There were no shifts in the subclone/main clone ratio depending on the MGUS, SMM, or MM stage of plasma cell dyscrasia. In multivariate analysis, t(11;14) was associated with lower rates of subclone formation and hyperdiploidy with higher rates. PC-AL itself lost statistical significance, demonstrating that the lower subclone frequency in AL is a reflection of its exceptionally high t(11;14) frequency. In summary, the subclone patterns in PC-AL and PC-non-AL are closely related, implying that subclone formation depends on the main cytogenetic categories and is independent of disease entity and stage.

Abstract
PURPOSE The wide heterogeneity in multiple myeloma (MM) outcome is driven mainly by cytogenetic abnormalities. The current definition of high-risk profile is restrictive and oversimplified. To adapt MM treatment to risk, we need to better define a cytogenetic risk classification. To address this issue, we simultaneously examined the prognostic impact of del(17p); t(4;14); del(1p32); 1q21 gain; and trisomies 3, 5, and 21 in a cohort of newly diagnosed patients with MM. METHODS Data were obtained from 1,635 patients enrolled in four trials implemented by the Intergroupe Francophone du Myélome. The oldest collection of data were used for model development and internal validation. For external validation, one of the two independent data sets was used to assess the performance of the model in patients treated with more current regimens. Six cytogenetic abnormalities were identified as clinically relevant, and a prognostic index (PI) that was based on the parameter estimates of the multivariable Cox model was computed for all patients. RESULTS In all data sets, a higher PI was consistently associated with a poor survival outcome. Dependent on the validation cohorts used, hazard ratios for patients in the high-risk category for death were between six and 15 times higher than those of patients in the low-risk category. Among patients with t(4;14) or del(17p), we observed a worse survival in those classified in the high-risk category than in those in the intermediate-risk category. The PI showed good performance for discriminating between patients who died and those who survived (Harrell's concordance index greater than 70%). CONCLUSION The cytogenetic PI improves the classification of newly diagnosed patients with MM in the high-risk group compared with current classifications. These findings may facilitate the development of risk-adapted treatment strategies.
