Here, we report the outcome of 226 myeloma patients presenting with extramedullary plasmacytoma or paraosseous involvement in a retrospective study conducted in 19 centers from 11 countries. Extramedullary disease was detected at diagnosis or relapse between January 2010 and November 2017. Extramedullary plasmacytoma and paraosseous involvement were observed in 130 patients at diagnosis (92 of 38) and in 96 at relapse (84 of 12). The median time from multiple myeloma diagnosis to the development of extramedullary disease was 25.1 months (range 3.1-106.3 months) in the relapse group (median follow up: 15 months). Imaging approach for extramedullary disease was computed tomography (n=133), positron emission tomography combined with computed tomography (n=50), or magnetic resonance imaging (n=35). The entire group received a median two lines of treatment and autologous stem cell transplantation (44%) following the diagnosis of extramedullary disease. Complete response was higher for paraosseous involvement versus extramedullary plasmacytoma at diagnosis (34.2% vs. 19.3%; P=NS.) and relapse (54.5% vs. 9%; P=0.001). Also paraosseous involvement patients had a better progression-free survival (PFS) when recognized at initial diagnosis of myeloma than at relapse (51.7 vs. 38.9 months). In addition, overall survival was better for paraosseous involvement compared to extramedullary plasmacytoma at diagnosis (not reached vs. 46.5 months). Extramedullary plasmacytoma at relapse had the worst prognosis with a PFS of 13.6 months and overall survival of 11.4 months. In the multivariate analysis, paraosseous involvement, extramedullary disease at diagnosis, International Staging System (ISS-I), and undergoing autologous stem cell transplantation improved overall survival independently. This cohort demonstrated that extramedullary disease benefits from front-line autologous stem cell transplantation and extramedullary plasmacytoma differs from paraosseous involvement in terms of rate and duration of response, with even worse outcomes when detected at relapse, constituting an unmet clinical need. © 2020 Ferrata Storti Foundation

Background: Patients with hematological malignancies (HM) are at high risk of mortality from SARS-CoV-2 disease 2019 (COVID-19). A better understanding of risk factors for adverse outcomes may improve clinical management in these patients. We therefore studied baseline characteristics of HM patients developing COVID-19 and analyzed predictors of mortality. Methods: The survey was supported by the Scientific Working Group Infection in Hematology of the European Hematology Association (EHA). Eligible for the analysis were adult patients with HM and laboratory-confirmed COVID-19 observed between March and December 2020. Results: The study sample includes 3801 cases, represented by lymphoproliferative (mainly non-Hodgkin lymphoma n = 1084, myeloma n = 684 and chronic lymphoid leukemia n = 474) and myeloproliferative malignancies (mainly acute myeloid leukemia n = 497 and myelodysplastic syndromes n = 279). Severe/critical COVID-19 was observed in 63.8% of patients (n = 2425). Overall, 2778 (73.1%) of the patients were hospitalized, 689 (18.1%) of whom were admitted to intensive care units (ICUs). Overall, 1185 patients (31.2%) died. The primary cause of death was COVID-19 in 688 patients (58.1%), HM in 173 patients (14.6%), and a combination of both COVID-19 and progressing HM in 155 patients (13.1%). Highest mortality was observed in acute myeloid leukemia (199/497, 40%) and myelodysplastic syndromes (118/279, 42.3%). The mortality rate significantly decreased between the first COVID-19 wave (March–May 2020) and the second wave (October–December 2020) (581/1427, 40.7% vs. 439/1773, 24.8%, p value < 0.0001). In the multivariable analysis, age, active malignancy, chronic cardiac disease, liver disease, renal impairment, smoking history, and ICU stay correlated with mortality. Acute myeloid leukemia was a higher mortality risk than lymphoproliferative diseases. Conclusions: This survey confirms that COVID-19 patients with HM are at high risk of lethal complications. However, improved COVID-19 prevention has reduced mortality despite an increase in the number of reported cases. © 2021, The Author(s).

Background: Multiple myeloma (MM) is predominantly a disease of the elderly, but approximately 10% of patients are younger than 50 years at diagnosis. Methods: This study aimed to investigate the clinical characteristics, treatment outcomes, and prognostic factors in younger MM patients using retrospective data from the Balkan Myeloma Study Group registry. Results: A total of 350 patients under 50 years old were included, comprising 10.4% of the overall cohort. The study found that younger patients had lower rates of renal impairment and anemia but a higher incidence of lytic bone disease and adverse cytogenetics. Treatment regimens, including proteasome inhibitors and immunomodulatory agents, were comparable between younger and older patients, but younger patients had significantly better complete response rates and overall survival (OS). The 5- and 10-year OS rates were 76% and 64%, respectively, with a projected median OS exceeding 15 years. Factors such as anemia, hypercalcemia, and high-risk cytogenetics were associated with worse survival outcomes. Autologous stem cell transplantation (ASCT) emerged as a key contributor to improved progression-free survival (PFS) and OS. Conclusion: In conclusion, younger MM patients exhibit distinct disease features and benefit from intensified treatment approaches, underscoring the need for tailored therapies to achieve potential disease cure. © 2025 The Author(s)

We have noticed an error in the progression-free survival of patients with extramedullary plasmacytoma in our article published in Haematologica in January 2020 (doi: HAEMATOL/2019/219295). The following sentence in the abstract: “Extramedullary plasmacytoma at relapse had the worst prognosis with a PFS of 13.6 months and overall survival of 11.4 months.” Should be replaced by: “Extramedullary plasmacytoma at relapse had the worst prognosis with a PFS of 9.1 months and overall survival of 11.4 months.” Likewise, on page 205, the following sentence: “However, if diagnosed at relapse, PFS and OS were 13.6 months and 11.4 months for EMP compared to 20.9 months (P=0.249) and 39.8 months (P=0.093) for PO, respectively (Table 2 and Figure 1).” Should be replaced by: “However, if diagnosed at relapse, PFS and OS were 9.1 months and 11.4 months for EMP compared to 20.9 months (P=0.249) and 39.8 months (P=0.093) for PO, respectively (Table 2 and Figure 1).” The error was also present in Table 2. The corrected Table 2 is shown below. © 2021 Ferrata Storti Foundation
