Autologous hematopoietic cell transplants (auto-HCTs) remain the standard of care for transplant-eligible MM patients. The general practice has been to undergo upfront apheresis following induction to collect sufficient number of CD34+ cells to facilitate two auto-HCTs. However, 5-30% of MM patients do not initially mobilise a sufficient number of hematopoietic stem cells and are classified as poor mobilizers (PM).

Therapy-related myeloid neoplasms (t-MN) are a complication of multiple myeloma (MM) treatment. Our retrospective, EBMT registry study included 157 such patients allografted (allo-HCT) between 2006 and 2018. Most patients (130) had a prior autologous HCT.

Article Synopsis
  • Autologous hematopoietic cell transplantation (AHCT) is an effective treatment for multiple myeloma, with real-world data collected from 61,725 patients revealing median overall survival of 90.2 months and median progression-free survival of 36.5 months.* -
  • Cumulative relapse incidence and non-relapse mortality rates at 24 months were found to be 33% and 2.5% respectively, with better outcomes linked to factors like younger age, certain disease subtypes, and high performance status.* -
  • Global variations were observed in patient outcomes based on registry data, influenced by differences in patient characteristics, use of maintenance treatments, and macroeconomic factors, highlighting the safety and effectiveness of AH

Salvage autologous hematopoietic cell transplantation (auto-HCT) may be used to treat relapse of plasma cell myeloma occurring after previous auto-HCT. When an insufficient number of hematopoietic stem cells have been stored from the initial harvest, remobilization is necessary. Here, we aimed to analyze the efficacy and safety of different doses of cytarabine (total 800 vs.

A Monte Carlo (MC) programme was written using the dose point kernel method to calculate doses in the roof zone of a building from nearby releases of radioactive gases. A Gaussian Plume Model (GPM) was parameterised to account for near-field building effects on plume spread and reflection from the roof. Rooftop recirculation zones and building-generated plume spread effects were accounted in a novel Dual Gaussian Plume (DGP) formulation used with the MC model, which allowed for the selection of angle of approach flow, plume release height in relation to the building and position of the release point in relation to the leading edge of the building.
