Article Synopsis
  • Umbilical cord blood (UCB) is a valuable stem cell source for patients without a matching donor, but its transplantation can lead to longer recovery times and higher complications.
  • This study aimed to assess the safety and feasibility of combining UCB transplantation with third-party mesenchymal stromal cells (MSC), focusing on treatment-related mortality (TRM) at day 100 and other outcomes.
  • Results showed that the combination is feasible, with a TRM of 18% at day 100, faster recovery times for blood cell counts, and minimal cases of graft versus host disease (GVHD), suggesting it may address some challenges associated with UCB transplantation.

Over the last decades, the survival of multiple myeloma (MM) patients has considerably improved. However, despite the availability of new treatments, most patients still relapse and become therapy-resistant at some point in the disease evolution. The mutation profile has an impact on MM patients' outcome, while typically evolving over time.

Article Synopsis
  • The analysis of bone marrow samples in multiple myeloma patients often misses the genetic diversity of the tumors.
  • Blood-derived liquid biopsies could offer a better way to assess this genetic variability, but a comprehensive comparison of different circulating biomarkers hasn't been published yet.
  • A study of 30 multiple myeloma patients found that cell-free DNA (cfDNA) provides the best match to bone marrow DNA mutation profiles, revealing that 16% of mutations were only found in circulating biomarkers.

Article Synopsis
  • - Erythrocytosis is a condition characterized by an increase in red blood cells and can arise from genetic (congenital) or external (acquired) factors, with congenital causes being rare.
  • - The study discusses five adults from three families who have erythrocytosis linked to heterozygous variants in the BPGM gene, including a new variant discovered.
  • - Functional tests indicated that these individuals exhibited partial BPGM deficiency, leading to lower levels of 2,3-bisphosphoglycerate and higher affinity of hemoglobin for oxygen, emphasizing the clinical significance of BPGM variations.

Introduction: Two phase 3 studies demonstrated superior efficacy of intravenous daratumumab (DARA IV) plus bortezomib/melphalan/prednisone (ALCYONE) or lenalidomide/dexamethasone (Rd; MAIA) versus standard-of-care regimens for transplant-ineligible newly diagnosed multiple myeloma. In these studies, patients could switch from DARA IV to subcutaneous daratumumab (DARA SC) while receiving daratumumab monotherapy in ALCYONE (as of Cycle 11) or daratumumab plus Rd in MAIA. The phase 3 COLUMBA study demonstrated noninferiority of DARA SC to DARA IV.

Allogeneic hematopoietic stem cell transplantation (HSCT) is the gold standard curative therapy for infants and children with many inborn errors of immunity (IEI), but adolescents and adults with IEI are rarely referred for transplant. Lack of published HSCT outcome data outside small, single-center studies and perceived high risk of transplant-related mortality have delayed the adoption of HSCT for IEI patients presenting or developing significant organ damage later in life. This large retrospective, multicenter HSCT outcome study reports on 329 IEI patients (age range, 15-62.

Detection of minimal residual disease (MRD) to guide therapy has been a standard practice in treatment of childhood acute lymphoblastic leukemia (ALL) for decades. In multiple myeloma (MM), a clear correlation is found between absence of MRD and longer survival. Quantitative allele-specific oligonucleotide (qASO)-PCR is the standard molecular method for MRD detection in these hematologic malignant tumors.

Study Question: Can oocytes extracted from excised ovarian tissue and matured in vitro be a useful adjunct for urgent fertility preservation (FP)?

Summary Answer: Ovarian tissue oocyte in-vitro maturation (OTO-IVM) in combination with ovarian tissue cryopreservation (OTC) is a valuable adjunct technique for FP.

What Is Known Already: Despite the impressive progress in the field, options for FP for cancer patients are still limited and, depending on the technique, clinical outcome data are still scarce.

Study Design, Size, Duration: This was a retrospective cohort study conducted at a university hospital-affiliated fertility clinic between January 2012 and May 2019.

Recent advances in the treatment of multiple myeloma have increased the need for accurate diagnosis of the disease. The detection of bone and bone marrow lesions is crucial in the investigation of multiple myeloma and often dictates the decision to start treatment. Furthermore, detection of minimal residual disease is important for prognosis determination and treatment planning, and it has underscored an unmet need for sensitive imaging methods that accurately assess patient response to multiple myeloma treatment.

Progression of multiple myeloma (MM) is largely dependent on the bone marrow (BM) microenvironment wherein communication through different factors including extracellular vesicles takes place. This cross-talk not only leads to drug resistance but also to the development of osteolysis. Targeting vesicle secretion could therefore simultaneously ameliorate drug response and bone disease.

Overcoming drug resistance is one of the greatest challenges in the treatment of multiple myeloma (MM). The interaction of myeloma cells with the bone marrow (BM) microenvironment is a major factor contributing to drug resistance. Tumour-associated macrophages (TAMs) with different polarization states constitute an important component of this microenvironment.

The bone marrow (BM) represents a complex microenvironment containing stromal cells, immune cells, osteoclasts, osteoblasts, and hematopoietic cells, which are crucial for the immune response, bone formation, and hematopoiesis. Apart from soluble factors and direct cell-cell contact, extracellular vesicles (EVs), including exosomes, were recently identified as a third mediator for cell communication. Solid evidence has already demonstrated the involvement of various BM-derived cells and soluble factors in the regulation of multiple biological processes whereas the EV-mediated message delivery system from the BM has just been explored in recent decades.
