COVID-19 in multiple myeloma patients: frequencies and risk factors for hospitalization, ventilatory support, intensive care admission and mortality -cooperative registry from the Grupo Brasileiro de Mieloma Multiplo (GBRAM).

INTRODUCTION: This study evaluated outcomes and risk factors for COVID-19 in 91 Brazilian multiple myeloma (MM) patients between April 2020 and January 2022. RESULTS: Of the 91 MM patients diagnosed with COVID-19, 64% had comorbidities and 66% required hospitalization due to COVID-19, with 44% needing ventilatory support and 37% intensive care. Age (OR 2.02; 95%CI 1.02 - 7.7) and hypertension OR 4.5; 95%CI 1.3 - 15.5) were independently associated with hospitalization and certain MM therapies (corticosteroids and monoclonal drugs) were associated with ventilatory support (OR 4.3; 95%CI 1.3 - 14 and OR 5.7; 95%CI 1.8 - 18, respectively), while corticosteroids and immunomodulatory drugs were linked to ICU admission (OR 5.1; 95% CI 1.4 - 18 and OR 3.4; 95%CI 1.1 - 10, respectively). The overall mortality rate was 30%, with the highest rate observed in the ICU (73%). Additionally, the ECOG performance status was linked to increased mortality (OR 11.5; 95%CI 1.9 - 69). The MM treatment was delayed in 63% of patients who recovered from COVID-19. CONCLUSIONS: The findings highlight the need for preventing COVID-19 and prioritizing vaccination among MM patients, as they have high rates of severe outcomes in the event of COVID-19. It is also essential to monitor the potential clinical impacts of COVID-19 on MM patients in the long-term. Given the limited resources available in treating MM patients in Brazil during the COVID-19 pandemic, outcomes might be worse in this population.

Superiority of the triple combination of bortezomib, cyclophosphamide and dexamethasone versus cyclophosphamide, thalidomide and dexamethasone in patients with newly diagnosed multiple myeloma, eligible for transplantation

ABSTRACT Background: The treatment of multiple myeloma (MM) has evolved significantly in the past decade, and new drug combinations have improved the response rates and prolonged survival. Studies comparing different induction chemotherapy regimens have shown that triple combinations have better results than double combinations. However, comparisons among different triple combinations are rare in the literature. Methods: We retrospectively compared two triple combinations comprising bortezomib, cyclophosphamide and dexamethasone (VCD) versus thalidomide, cyclophosphamide and dexamethasone (CTD), and aimed at identifying which of the two combinations would yield better response rates following four induction cycles prior to hematopoietic cell transplantation in patients with untreated multiple myeloma. Results: We retrospectively reviewed the medical records of 311 patients from 24 different centers.The VCD regimen was used as induction therapy by 117 (37.6%) patients, whereas 194 (62.4%) patients received the CTD regimen. After four cycles of induction on an intention-to-treat basis, 54% of the patients in the VCD group achieved at least very good partial response versus 42.8% in the CTD group (p = 0.05). We observed no difference in neuropathy or thrombotic events rates among the two regimens. Conclusion: Our results corroborate the superiority of the triple combination regimes containing bortezomib over the triple combination with thalidomide as pre ASCT induction therapy in MM.

Unmet needs in multiple myeloma in Brazil from physicians' perspective ­ barriers in quality of life and disease management / Necessidades não atendidas em mieloma múltiplo no Brasil sob a perspectiva de médicos ­ barreiras na qualidade de vida e manejo da doença

Objective: There is an increasing trend of the overall survival rates of multiple myeloma (MM) patients over the years, increasing the necessity to improve their quality of life and attenuate unmet medical needs. Therefore, this study aims to explore and describe unmet medical needs and barriers in Brazilian MM patients, based on physicians' perspective. Methods: A questionnaire with 41 questions was developed to collect information regarding clinical characteristics, unmet medical needs and barriers for the diagnosis and treatment of MM in Brazil. After physicians' responses, a panel discussion with all the participants was had in order to collect additional data and validate physicians' responses. Results: Participants had a mean of 18 years of professional experience and attended to mean of thirty MM patients per month. MM patients treated by these physicians had a median time of disease of 7.5 months when initiating treatment in the public sector, and 2.5 months in the private sector. In both systems, the majority of patients referred were from general practitioners. Peripheral neuropathy was the most common adverse event reported with higher impact on patients' adherence and QoL. Conclusion: There are several challenges as to unmet medical needs, especially when comparing the private and public healthcare systems in Brazil. According to physicians, providing access to basic diagnostic procedures and adopting educational measures for both physicians and patients would help to minimize barriers in the current scenario of MM management in Brazil.

Objetivo: Existe uma tendência no aumento das taxas de sobrevida global de pacientes de mieloma múltiplo (MM) ao longo dos anos, aumentando a necessidade de melhorar sua qualidade de vida e atenuar as necessidades médicas não atendidas na área. Desta forma, o objetivo deste estudo explorar e descrever as necessidades médicas não atendidas e as barreiras em pacientes brasileiros de MM, a partir da perspectiva de médicos. Métodos: Um questionário com 41 questões foi desenvolvido para coletar dados sobre as características clínicas, necessidades médicas não atendidas e barreiras no diagnóstico e tratamento de MM no Brasil. Depois de coletar a resposta dos médicos, uma discussão em forma de painel com todos os participantes foi realizada para coletar dados adicionais validar as respostas do questionário. Resultados: Os participantes tinham, em média, 18 anos de experiência profissional, atendendo-se no total uma média de 30 pacientes de MM por mês. Os pacientes de MM atendidos por esses médicos no sistema público apresentam em média 7,5 meses de doença ao iniciar o tratamento, enquanto no sistema privado apresentavam 2,5 meses. Em ambos os sistemas, a maioria dos pacientes foi referenciada por clínicos gerais. Neuropatia periférica foi o evento adverso mais frequentemente reportado pelos médicos, com maior impacto na adesão ao tratamento e na qualidade de vida. Conclusão: Existem diversos desafios relativos às necessidades médicas não atendidas, especialmente ao comparar os sistemas público e privado no Brasil. De acordo com os participantes, o acesso aos procedimentos diagnósticos básicos e a adoção de medidas de educação médica e de pacientes minimizariam as barreiras importantes no cenário brasileiro atual.
