Background The use of bendamustine with an anti-CD20 monoclonal antibody as frontline therapy for indolent non-Hodgkin lymphoma (NHL) has become a standard of care. We aimed to evaluate the real-world efficacy and safety of bendamustine-rituximab (BR) frontline therapy for indolent NHL. Patients and methods Patients with indolent NHL treated with frontline BR therapy in Hôpital du Sacré-Coeur de Montréal, from January 2015 to August 2018 were included in this retrospective study.

Article Synopsis
  • Plasma cell leukemia (PCL) is a rare and aggressive blood cancer with two forms: primary (pPCL) and secondary (sPCL), but information on it is limited due to its low incidence.* -
  • A study involving 99 patients found that pPCL has a significantly better survival rate and progression-free survival compared to sPCL, which shows very short survival times and tends to arise from high-risk multiple myeloma cases.* -
  • The research indicates no improvement in survival rates for PCL over time and emphasizes the critical need for better treatment strategies to address this serious condition.*

One of the most widely accepted conditioning regimens for hematopoietic stem cell transplantation (HSCT) is BEAM (carmustine, etoposide, cytarabine, melphalan). However, a recent increase in the cost of carmustine has limited its use bringing our institution to replace carmustine with bendamustine. This observational retrospective single-center study aims to report the efficacy and safety of the BeEAM regimen.

Despite novel drugs and autologous HCT, MM remains incurable, with short survival in patients with poor biological characteristics. Allo HCT may be curative in some patients but is hampered by high rates of toxicity and relapse. We hypothesized that bortezomib (BTZ), with its anti-myeloma and immunologic properties, could improve PFS and cGVHD after allo HCT in newly diagnosed MM patients.

Background-smoldering multiple myeloma (SMM) risk of progression to multiple myeloma (MM) is highly heterogeneous and several models have been suggested to predict this risk. Lakshman et al. recently proposed a model based on three biomarkers: bone marrow plasma cell (BMPC) percentage > 20%, free light chain ratio (FLCr) > 20 and serum M protein > 20 g/L.

Introduction: In patients with relapsed or refractory lymphoma, high-dose chemoimmunotherapy with subsequent autologous hematopoietic cell transplantation (HCT) is a standard of care. Bendamustine, an alkylating agent, is used in the BeEAM (bendamustine, etoposide, cytarabine, melphalan) protocol for conditioning therapy before autologous HCT in patients with relapsed or refractory lymphoma who are eligible for transplant. There is no consensus regarding an optimal salvage regimen and the approach varies according to toxicity.

Multiple myeloma (MM) is a rare hematologic disease of antibody-secreting plasma cells. Our understanding of the pathogenesis of this malignancy has improved greatly, and at the same time, we have access to new and more effective treatments options. Over the last 5 years, a spectrum of novel therapies with different mechanisms of action, including third-generation immunomodulatory drugs (pomalidomide), second generation proteasome inhibitors (carfilzomib and ixazomib), a histone deacetylase inhibitor (panobinostat) and monoclonal antibodies (mAbs) (elotuzumab and daratumumab) has transformed our approach to the treatment of patients with relapsed/refractory MM (RRMM).

Multiple myeloma (MM), a mature B-cell neoplasm, is the second most common hematologic malignancy worldwide. Despite significant improvements in outcome with new therapies, the majority of responding patients will eventually develop resistance to treatment. Furthermore, patients swith disease refractory to both proteasome inhibitors and immunomodulatory drugs (IMiDs) have a poor prognosis.
