Multiple myeloma (MM) is linked to chronic NF-κB activity in myeloma cells, but this activity is generally considered a cell-autonomous property of the cancer cells. The precise extent of NF-κB activation and the contributions of the physical microenvironment and of cell-to-cell communications remain largely unknown. By quantitative immunofluorescence, we found that NF-κB is mildly and heterogeneously activated in a fraction of MM cells in human BMs, while only a minority of MM cells shows a strong activation...

While the advent of CAR-T therapies has heralded a new era of efficacious therapies in relapsed/refractory Multiple Myeloma, access continues to be a major limiting factor due to prolonged manufacturing times of autologous products and apheresis and/or manufacturing failures. Allogeneic adoptive cellular therapy products (CAR-T, CAR-NK), currently investigational, are "off-the-shelf" products that may address availability and manufacturing bottlenecks. Novel rapid manufacturing platforms that decrease adoptive cell therapy product development time by weeks are currently being tested in clinical trials and may additionally help bridge the demand-supply chasm...

Isatuximab, a novel anti-CD38 monoclonal antibody, is approved in combination with carfilzomib and dexamethasone (Isa-Kd) in relapsed/refractory multiple myeloma (RRMM) patients. Because of its recent introduction, real-world efficacy and safety are poorly reported. In this Italian multicenter real-life observational retrospective study, efficacy and safety of the Isa-Kd regimen were evaluated in a cohort of 103 RRMM patients. Overall response rate (ORR) was 85%, with stringent (sCR) or complete response (CR) in 18% of cases and very good partial response (VGPR) in 39%...

As in other organs, the diagnosis of endogenous cutaneous overload diseases is based on histopathological analysis of the lesions using special stainings, even if the clinical appearance is sometimes very suggestive. The lesions are sometimes very subtle and can be included in the group of "invisible" dermatoses, such as primary macular cutaneous amyloidosis or calciphylaxis. Superficial dermal melanosis or pigmentary incontinence generally reflects the post-inflammatory stage of a chronic or recurrent interface dermatitis...

BACKGROUND: T-cell lymphomas are a heterogeneous group of lymphoid malignancies with poor outcomes. Frontline multiagent chemotherapy options include CHOP (prednisone, vincristine, cyclophosphamide, and doxorubicin), brentuximab-CHP, CHOEP, and EPOCH (etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin). PATIENTS AND METHODS: We report our single institution data for safety and efficacy of EPOCH in 38 patients with aggressive T-cell lymphoma including both peripheral T cell lymphoma (PTCL) and cutaneous T-cell lymphoma (CTCL)...

PURPOSE: Many clinical trials of therapeutic interventions for multiple myeloma do not use patient important outcomes and rely on the use of surrogate endpoints. The aim of this systematic review was to depict the landscape of randomized controlled trials in myeloma research and compile the endpoints utilized. METHODS: We searched Embase, PubMed, and the Cochrane Library for randomized controlled trials in myeloma published in English up to October 2023. We included trials exploring efficacy of therapeutic modalities for myeloma itself or supportive care interventions...

BACKGROUND: Plerixafor is an adjunct peripheral blood stem cell (PBSC) mobilization agent with well-demonstrated safety and efficacy. The routine use of the originator brand drug (Mozobil) has been limited by cost. This retrospective study was conducted to compare the mobilization efficacy of a lower-cost generic plerixafor and Mozobil in multiple myeloma (MM) patients. STUDY DESIGN AND METHODS: The study included two near-concurrent cohorts of MM patients mobilized with brand (n = 64) or generic (n = 61) plerixafor in addition to filgrastim...

BACKGROUND Simultaneous occurrence of chronic lymphocytic leukemia (CLL) and plasma cell myeloma (PCM) is an uncommon hematological condition, with most patients presenting in late adult life. When these diagnoses occur concurrently, it often poses diagnostic challenges to the pathologist, with other important differential diagnoses including lymphoplasmacytic lymphoma, marginal-zone lymphoma, and chronic lymphocytic leukemia with plasmacytoid differentiation. Ancillary studies are indispensable in arriving at a reliable diagnosis in this clinical scenario...

Resveratrol (RSV) is a nutraceutical compound belonging to the nonflavonoid polyphenol family, whose antioxidants, anti-inflammatory, and antitumoral properties have been widely investigated. The ability of RSV to provide beneficial effects for neurological, cardiovascular, and cancer disorders rekindled the interest to explore the molecular mechanisms behind its pleiotropic effects, which are due to the modulation of coding and noncoding genes involved in many key biological pathways. With a computational approach, including docking studies and thermodynamics calculations followed by 200-ns-long molecular dynamics and a clustering analysis, we hypothesized the stabilizing binding between RSV and G4 structures of telomeric repeat-containing RNA (TERRA), which is a tumor-suppressive long noncoding RNAs (lncRNA) involved in the regulation of telomere maintenance...

Ciltacabtagene autoleucel (cilta-cel) CAR-T therapy was approved in 2022 for patients with relapsed/refractory multiple myeloma (RRMM). We report outcomes with cilta-cel in the standard-of-care setting. Patients with RRMM who underwent leukapheresis for cilta-cel manufacturing between 3/1/2022-12/31/2022 at 16 US academic medical centers were included. RESULTS: 255 patients underwent leukapheresis and 236 (92.5%) received cilta-cel. Of leukapheresed patients, 56% would not have met CARTITUDE-1 trial eligibility criteria...

Recent therapeutic advances have significantly improved the outcome for patients with multiple myeloma (MM). The backbone of successful standard therapy is the combination of Ikaros degraders, glucocorticoids, and proteasome inhibitors that interfere with the integrity of myeloma-specific superenhancers by directly or indirectly targeting enhancer-bound transcription factors and coactivators that control expression of MM dependency genes. T cell engagers and chimeric antigen receptor T cells redirect patients' own T cells onto defined tumor antigens to kill MM cells...

BACKGROUND: Minimal residual disease (MRD) testing is a promising approach to tailor the treatment of multiple myeloma (MM). However, several major concerns remain to be addressed before moving it into daily practice, most of which stem from the dynamic natures of the MRD status. Thus, it is crucial to understand the MRD dynamics and propose its clinical implications. METHODS: We retrospectively analysed the data of patients with newly diagnosed MM (NDMM) who had flow cytometry-based MRD test at multiple time points after initiation of therapy...

Introduction Although recent data suggest that Melphalan high-dose therapy followed by autologous stem cell transplantation (HDT/ASCT) is safe and effective in eligible multiple myeloma (MM) patients up to the age of 75 years, its value in elderly MM patients is still controversially discussed. Methods We retrospectively analyzed 607 MM patients ≥ 60 years old, who were admitted to our institution for first-line or salvage HDT/ASCT between January 2007 and October 2018. We assigned them to three groups according to age at HDT/ASCT: 60-64 years (S1), 65-69 years (S2) and ≥ 70 years (S3)...

OBJECTIVE: The objective of this study is to determine if there are differences in outcome for patients diagnosed with multiple myeloma in a rural setting compared to a metropolitan setting and which factors influence these outcomes. DESIGN: Retrospective cohort study. SETTING: Illawarra Shoalhaven Local Health District. PARTICIPANTS: A total of 391 patients diagnosed with multiple myeloma between 2000 and 2022. MAIN OUTCOME MEASURES: Treatment and survival outcomes of these patients...

Despite significant advancements in multiple myeloma (MM) treatment, including novel therapies and combination strategies, the translation of findings from randomized controlled trials (RCTs) into real-world clinical practice has been associated with several challenges. Specifically, the principles and criterion that shape the current design of MM RCTs have left out a sizable portion of patients that would particularly benefit from trial inclusion. In addition, RCTs may use primary outcomes which only partially cover patient-relevant endpoints important for evaluating treatment efficacy and quality of life...
