RESUMEN
High-dose chemotherapy followed by autologous stem cell transplantation (auto-SCT) is the standard treatment for young patient ≤65 years with multiple myeloma (MM). The role of auto-SCT in elderly patients older than 70 years remains controversial in the era of novel agents and especially since the recent introduction of monoclonal antibodies (AbMo). In this study, we evaluated 12 patients with MM over 70 years old undergoing auto-SCT (elderly graft cohort) in seven centers of GIMEMA Working Group Lazio. We compared the baseline characteristics, treatment and outcome with 97 MM elderly patients who did not receive auto-SCT (nontransplant patients) from the same registry who were ≥ 70 years old, but did not undergo auto-SCT. The median progression free survival (PFS) for graft versus no-graft cohort was 56.4 versus 26.1 months, respectively. There was a trend for better PFS among graft compared to nontransplant patient (p = .1). On the other hand, the median overall survival for transplant versus nontransplant cohort was 107.6 versus 49.5 months (p = .02). Despite the small number of patients aged ≥70 years and ≤74 years, it seems that auto-SCT is well tolerated, safe and effective. Therefore, we propose that it should be considered an important treatment option in the era of new drugs in elderly fit patients with MM.

Flow cytometry is a highly sensitive and specific approach for discriminating between normal and clonal plasma cells in multiple myeloma. Uniform response criteria after treatment have been established by the International Myeloma Working Group and the EuroFlow Group; however, the way in which flow cytometry data are reported has suffered from no collaborative or multicentre efforts. This study, involving 8 expert laboratories and 12 clinical hematology units of the Lazio region in Italy, aims to produce a uniform and shared report among the various Centres. From the pre-analytical phase to sample processing, data acquisition, analysis, and evaluation of the potential limitations and pitfalls of the entire process, the study reaches a final conclusion shared by laboratories and clinicians according to the most updated principles and recommendations. The aim was to identify the necessary data to be included in the clinical report by using multiple-choice questionnaires at every single stage of the process. An agreement of more than 75% of the laboratories was considered mandatory for the data to be included in the report. By ensuring the operational autonomy of each laboratory, this study provides a clear report that limits subjective interpretations and highlights possible bias in the process, better supporting clinical decision-making.
RESUMEN
We report our retrospective analysis on 34 relapsed/refractory multiple myeloma (RRMM) patients treated with daratumumab based triplets. Twenty patients were females and 14 males. Median age was 73.2. Daratumumab was associated to lenalidomide in and dexamethasone (DRd) in 30 (88,3%) and to bortezomib and dexamethasone (DVd) in 4 cases (11,7%). The ORR was 88%. CR occurred in 12% of cases, VGPR in 44% and PR in 32%. The 12 months PFS and OS rates were 78% and 86,5%, respectively. Present data confirm those recently reported in the literature and further reinforce the early use of daratumumab-based triplets for RRMM patients.
