The article discusses the use of teclistamab, a humanized immunoglobulin bispecific antibody, in patients with relapsed/refractory multiple myeloma (RRMM) who are on dialysis. The study, conducted in France, included 15 dialysis-dependent RRMM patients who were treated with teclistamab. The results showed promising responses in most patients, with manageable side effects such as cytokine release syndrome and infections. The study suggests that teclistamab monotherapy could be a feasible and safe option for patients with dialysis-dependent RRMM who are typically excluded from clinical trials.

Ixazomib (IXA) is an oral proteasome inhibitor (PI) used in combination with lenalidomide and dexamethasone (IXA-Rd) for patients with relapsed and/or refractory multiple myeloma (RRMM). The REMIX study is one of the largest prospective, real-world analysis of the effectiveness of IXA-Rd in the setting of RRMM. Conducted in France between August 2017 and October 2019, the REMIX study, a non-interventional prospective study, included 376 patients receiving IXA-Rd in second line or later and followed for at least 24 months. Primary endpoint was the median progression-free survival (mPFS). Median age was 71 years (Q1-Q3 65.0 – 77.5) with 18.4% of participants older than 80 years. IXA-Rd was initiated in L2, L3 and L4 + for 60.4%, 18.1% and 21.5%, respectively. mPFS was 19.1 months (95% CI [15.9, 21.5]) and overall response rate (ORR) was 73.1%. mPFS was 21.5, 21.9 and 5.8 months in patients receiving IXA-Rd as L2, L3, L4 + respectively. Among patients receiving IXA-Rd in L2 and L3, mPFS was similar for patients previously exposed to lenalidomide (19.5 months) than for those lenalidomide naive (not exposed, 22.6 months, p = 0.29). mPFS was 19.1 months in patients younger than 80 years and 17.4 months in those 80 years or older (p = 0.06) with similar ORR (72.4% and 76.8%) in both subgroups. Adverse events (AEs) were reported in 78.2% of patients including 40.7% of treatment-related AE. IXA discontinuation was due to toxicity in 21% of patients. To conclude, the results of the REMIX study are consistent with the results of Tourmaline-MM1 and confirm the benefit of IXA-Rd combination in real life. It shows the interest of IXA-Rd in an older and frailer population, with an acceptable effectiveness and tolerance. [ABSTRACT FROM AUTHOR]

We also show that the presence of I TP53 i mutation and hypoalbuminemia (<36 g/L) are 2 independent PF for PFS and OS in elderly MCL patients included in the cohort. B Introduction: b Alterations in I TP53 i are a well known negative factor in young mantle cell lymphoma (MCL) patients eligible for intensive therapies, but their impact in elderly subjects remains poorly characterized. Long-term analysis of the RiBVD phase II trial reveals the unfavorable impact of TP53 mutations and hypoalbuminemia in elderly mantle cell lymphoma patients. [Extracted from the article]

Splenectomy remains the preferred treatment for chronic immune thrombocytopenia (ITP) after corticosteroid failure, despite the risks of despite surgical complications and infection. The aim of this study was to assess the efficacy of and tolerance to rituximab through a retrospective analysis of 35 refractory/relapsing ITP patients treated from 2004 to 2013. The median age of subjects was 46 years (14-80). Rituximab was given at a weekly dose of 375 mg/m(2) for 4 weeks. Median time from diagnosis to first infusion was 17 months (1-362) and follow-up was 47 months (2-133). The overall response rates at 1 and 2 years after the first infusion were 47 and 38 %, with complete response rates of 24 and 25 %, respectively. Median duration of response was 38 months (1-123), with 37 % of patients maintaining a durable response (>1 year). Twenty-nine percent of patients had undergone splenectomy. A durable response after rituximab was more frequently observed in patients undergoing second-line therapy than those in third or later (83 versus 35 %, P = 0.01). Forty-four percent of patients experienced mild hypogammaglobulinaemia after rituximab, and no clinical infection occurred. To conclude, rituximab should be considered as an alternative treatment to splenectomy. Its efficacy and safety profile should lead us to choose this medical option therapy before surgery for ITP patients. [ABSTRACT FROM AUTHOR]

Cervical bilateral lymphadenopathy is a frequent event during chronic lymphocytic leukemia (CLL) natural history. However, lymph node biopsy is generally not required as long as transformation into an aggressive lymphoma (Richter syndrome) is not suspected. We present here a rare case of CLL patient who developed progressive bilateral cervical lymph node and bilateral tonsillar hypertrophy. CLL front-line therapy was ineffective leading to adenectomy and diagnosis of concomitant extramedullary plasmacytoma. Radiotherapy did not result in the disappearance of lymphadenopathy. Adenectomy should be performed in CLL cases to avoid misdiagnosis. [ABSTRACT FROM AUTHOR]

IgE multiple myeloma is a rare disease characterized by a high frequency of Bence-Jones proteinuria and plasma cell leukaemia when compared to other isotypes of monoclonal proteins. Only 35 cases have been reported. We describe a 70-year-old woman with a stage III IgE kappa multiple myeloma presenting with a sacral plasmacytoma. Immunological and biochemical studies showed IgE kappa producing tumoral plasma cells. Serum total IgE was high without clinical symptoms suggesting an hyperIgE syndrome or mast cell activation. The patient underwent surgical removal of the sacral tumor and monthly melphalan-prednisone treatment together with intravenous pamidronate infusions. Magnetic Resonance Imaging (MRI) of the dorsolumbar spine revealed an epidural process leading to T6–T9 radiotherapy. Bone densitometry showed a decreased bone mineral content supporting the management of myeloma-related osteoporosis with bisphosphonate infusions. [ABSTRACT FROM AUTHOR]
