Novelties on Multiple Myeloma from the Main 2024 Hematology Conferences.

Despite the introduction of several therapies in recent years, multiple myeloma (MM) remains a hematologic malignancy difficult to treat due to its extreme inter- and intra-patient heterogeneity. However, at the 2024 major international conferences, very significant data have emerged on new approaches that can improve outcomes even in high-risk or very advanced diseases. Up-front quadruplet combinations, including anti-CD38 monoclonal antibodies, proved to be the best therapy in terms of depth of response and long-term efficacy in both transplant-eligible and not-eligible patients with MRD assessment that could play a key role in determining the duration of therapy, avoiding unnecessary overtreatment.

Long-Term Survival with Multiple Myeloma: An Italian Experience.

Background/objectives: Treatments for multiple myeloma (MM) have expanded in the last decade, and the overall survival (OS) of MM patients (pts) is in continuous improvement. With the availability of new treatments and the use of high-dose chemotherapy, followed by autologous hematopoietic stem cell transplantation (ASCT), the median OS of newly diagnosed MM (NDMM) pts is 6-8 years. To date, approximately 50% and 28% of MM patients are still alive at 5 years and 10 years.

The Challenging Approach to Multiple Myeloma: From Disease Diagnosis and Monitoring to Complications Management.

The outcome of multiple myeloma (MM) has significantly improved in the last few decades due to several factors such as new biological discoveries allowing to better stratify disease risk, development of more effective therapies and better management of side effects related to them. However, handling all these aspects requires an interdisciplinary approach involving multiple knowledge and collaboration of different specialists. The hematologist, faced with a patient with MM, must not only choose a treatment according to patient and disease characteristics but must also know when therapy needs to be started and how to monitor it during and after treatment.

Autologous Stem Cell Transplantation in Multiple Myeloma: Where Are We and Where Do We Want to Go?

The introduction of high-dose therapy in the 1990s as well as the development of drugs such as thalidomide, lenalidomide, and bortezomib in the 2000s led to an impressive improvement in outcome of patients with multiple myeloma (MM) eligible for autologous stem cell transplantation (ASCT). Clinical trials conducted in the first ten years of the twenty-first century established as standard therapy for these patients a therapeutic approach including induction, single or double ASCT, consolidation, and maintenance therapy. More recently, incorporating second-generation proteasome inhibitors carfilzomib and monoclonal antibody daratumumab into each phase of treatment significantly improved the efficacy of ASCT in terms of measurable residual disease (MRD) negativity, Progression Free Survival (PFS), and Overall Survival (OS).
