Background: To date, the only potential curative treatment for multiple myeloma (MM) remains allogeneic (allo) hematopoietic cell transplant (HCT), although, most patients will eventually relapse. In relapsed patients, donor lymphocyte infusions (DLIs) have been reported to control disease, but the optimal strategy prior to and doses of DLIs remain unclear. With this study (NCT03413800), we aimed to investigate the efficacy and toxicity of lenalidomide and dexamethasome (Len/Dex) followed by escalating pre-determined doses of DLIs in MM patients who relapsed after allo HCT.

Fluorescence in situ hybridization (FISH) on enriched CD138 plasma cells is the standard method for identification of clinically relevant genetic abnormalities in multiple myeloma. However, FISH is a targeted analysis that can be challenging due to the genetic complexity of myeloma. The aim of this study was to evaluate the potential of optical genome mapping (OGM) to detect clinically significant cytogenetic abnormalities in myeloma and to provide larger pangenomic information.

Multiple myeloma usually affects older adults. However, younger patients constitute a significant subset as approximately 10% of cases occur in subjects younger than 50 years old. Young patients, who are underrepresented in the literature, are diagnosed during their most productive years of life, urging the need for tailored treatment approaches.

Allogeneic hematopoietic cell transplantation (HCT) has curative potential in myeloma but remains hampered by high rates of relapse and chronic graft-versus-host disease (GVHD). We hypothesized that bortezomib (BTZ) as maintenance therapy after allo HCT could not only decrease the incidence of relapse but also the incidence and severity of chronic GVHD. The primary endpoint of this study was to determine whether BTZ maintenance decreases the incidence and severity of chronic GVHD using National Institutes of Health (NIH) criteria.

Monoclonal gammopathy associated with dermatological manifestations are a well-recognized complication. These skin disorders can be associated with infiltration and proliferation of a malignant plasma cells or by a deposition of the monoclonal immunoglobulin in a nonmalignant monoclonal gammopathy. These disorders include POEMS syndrome, light chain amyloidosis, Schnitzler syndrome, scleromyxedema and TEMPI syndrome.

Article Synopsis
  • Recent advancements in the treatment of multiple myeloma have improved outcomes, but the disease remains incurable, especially for patients with high-risk genetic markers or advanced stages.
  • Allogeneic transplantation offers potential curative benefits for some patients but comes with risks, including high non-relapse mortality and chronic graft-versus-host disease, leading to debates about its use.
  • The review will focus on the effectiveness and timing of allogeneic transplants, discussing both upfront and delayed approaches in the treatment of multiple myeloma.

Despite high cure rates with frontline therapy for Hodgkin lymphoma (HL), approximately 30% of patients will relapse or develop primary refractory disease (R/r). Autologous hematopoietic stem cell transplantation (autoHSCT) is the standard of care for R/r disease, and allogeneic HSCT (alloHSCT) is a curative option for patients in second relapse. Novel agents are being incorporated for the treatment of R/r HL, such that the optimal timing of transplantation is currently being challenged.

Background: Long-term survival in patients progressing after tandem autologous-allogeneic stem cell transplant (SCT) has been reported, suggesting a persistent graft-vs-myeloma (GvM) effect even after post-transplant progression.

Methods: In order to confirm this observation, we updated the results of our previously published cohort of 92 newly diagnosed myeloma patients who received tandem transplant and compared them with 81 contemporary patients who received autologous transplant only.

Results: With a median follow-up of 13.

Article Synopsis
  • Haplo-identical donors are being increasingly used for stem cell transplants in patients with severe aplastic anemia who don't have matched donors.
  • Single cord blood transplants are promising, but adult patients face issues like low cell counts leading to prolonged cytopenias and infection risks.
  • The successful case of an adult patient receiving a UM171-expanded cord blood graft highlights a viable transplantation option, showing full donor acceptance and no severe complications.

Background: Early assessment of cognitive symptoms is an issue in geriatrics. This study investigated the delay from the onset of cognitive symptoms to initial clinical assessment and its associations with patients' sociodemographic and clinical characteristics.

Methods: This is a cross-sectional retrospective study using medical chart review of 316 patients referred for assessment to a university-affiliated memory clinic.
