Safety and cost effectiveness of outpatient autologous hematopoietic stem cell transplantation for multiple myeloma â single-center experience of a pilot Early Discharge Program
Introduction: Multiple myeloma (MM) is the leading indication for autologous stem cell transplantation (ASCT), with over 12,000 transplants per year in Europe. Due to low toxicity, an entirely outpatient procedure or an early discharge after ASCT can be considered as alternatives to inpatient transplantation. Thus, we launched an Early Discharge Program (EDP) for patients qualified for ASCT due to MM who were under 60 years of age, without significant comorbidities, who had a caregiver available 24/7, and who lived within a 60-minute drive of our hospital.
Material and methods: Patients spent 72 hours in the hospital being administered melphalan 200 mg/m2 intravenous followed by an infusion of hematopoietic stem cells. They were eventually discharged and remained under outpatient care. The program was launched in September 2019 and was temporarily halted due to the coronavirus disease 19 (COVID-19) pandemic in early 2020. Five patients were enrolled to the EDP.
Results: Non-hematological toxicity was mild and manageable in an outpatient setting. Only one patient was readmitted due to exacerbation of ulcerative colitis that was probably not related to ASCT. We observed neither infections nor bleeding. Due to hematological toxicity, three of the five patients received platelet transfusion on the 6th day after ASCT as outpatients. No packed erythrocytes were transfused. The EDP demonstrated lower costs compared to an inpatient approach.
Conclusions: We believe that early discharge, which is an intermediate step to full at-home transplantation due to patientsâ wellbeing, reduction of infections caused by resistant microorganisms, and costs, will eventually replace a full inpatient procedure for a significant population of patients suffering from multiple myeloma and indeed other diseases
Neutropenic enterocolitis and multidrug-resistant bacteria colonization in lymphoma patients undergoing autologous stem cell transplantation
Introduction: There is little iterature data regarding neutropenic enterocolitis (NE) development after autologous hematopoietic cell transplantation (auto-HCT) in non-Hodgkin lymphoma (NHL) patients. The aim of this study was to determine the incidence, risk factors, and clinical outcome of NE after auto-HCT in NHL patients with respect to the impact of multidrug-resistant Gram-negative bacteria (MDRG) and vancomycin-resistant enterococci colonization on the early outcome after auto-HCT. Material and methods: This retrospective single-center analysis included a total of 65 NHL patients who underwent auto-HCT after BEAM (BCNU, etoposide, cytosine arabinoside, melphalan) conditioning (BEAM-auto-HCT). Results: NE was diagnosed in nine (13.8%) patients, a median four days after auto-HCT. In 6/9 (66%) patients, septic shock following NE was diagnosed. In univariate analysis, MDRG colonization before BEAM-auto-HCT was the only factor significant for NE development [odds ratio (OR) 2.4 (1.14â5.0), p = 0.027], although this was not confirmed in multivariate analysis. Additionally, NE [OR 5.2 (1.9â13.9), p = 0.001] and MDRG colonization prior to transplant [OR 2.7 (1.0â7.0), p = 0.041] were independent factors for septic shock development. Conclusions: Our findings suggest that NHL patients presenting with MDRG colonization before transplant should be kept under careful surveillance because of the high risk of the development of early severe infectious complications, including abdominal ones
CAR-T cell therapy â toxicity and its management
Chimeric antigen receptor T-cell (CAR-T) therapy is an effective new treatment for hematologic malignancies. Two anti-CD19 CAR-T products, namely axicabtagene ciloleucel and tisagenlecleucel, have been approved for the management of relapsed/refractory large B-cell lymphoma after two lines of systemic therapy. Additionally, tisagenlecleucel is indicated for refractory acute lymphoblastic leukemia in pediatric patients and young adults up to 25 years of age. CAR-T cells are undoubtedly a major breakthrough therapy in hematooncology resulting in up to 90% response rate with durable remissions in population with refractory high-risk disease. However, there are serious side effects resulting from CAR-T therapy, including cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS). Manifestations of CRS mostly include fever, hypotension, hypoxia, and end organ dysfunction. Neurologic toxicities are diverse and include encephalopathy, cognitive defects, dysphasia, seizures, and cerebral edema. Since the symptoms are potentially severe, practitioners need to familiarize themselves with the unique toxicities associated with these therapies. In this article, we present a practical guideline for diagnosis, grading and management of CRS and CAR-T neurotoxicity. In addition, infectious complications and late toxicities including prolonged cytopenias and hypogammaglobulinemia are discussed
Nivolumab for relapsed/refractory classical Hodgkin lymphoma after brentuximab vedotin failure â Polish Lymphoma Research Group real-life experience
AimPolish centers analyzed retrospectively the real-life experience with nivolumab in relapsed/refractory (R/R) classical Hodgkin lymphoma (cHL) patients, after brentuximab vedotin (BV ) failure. BackgroundDespite the effective frontline treatment, for cHL patients relapsing after autologous stem cell transplantation, the only effective strategy remains the novel agents. Nivolumab, a checkpoint inhibitor, demonstrates the clinical benefit with an acceptable safety profile. Materials and methodsRetrospective analysis included 16 adult patients with R/R cHL after BV failure. All patients received single-agent nivolumab 3 mg/kg every 2 weeks until disease progression or unacceptable toxicity. ResultsAfter six cycles of nivolumab the overall response rate was 81% (complete remission rate of 56%, partial remission rate of 25%). The median PFS was not reached after a median follow-up of 19 months. Adverse events (AEs) of any grade occurred in 12 patients (75%), including grade 3 AEs observed in 5 patients (31%). There were no AEs of grade 4 or 5. After a median of 25 nivolumab doses, 62% of responding patients proceeded to allogeneic stem cell transplantation. ConclusionNivolumab monotherapy demonstrated a high efficacy and safety in R/R cHL patients after BV failure. More patients and longer follow-up may further establish the potential benefit
Road to clinical implementation of CAR-T technology in PoznaĆ
The objective of this paper is to present the process of the national and international accreditation leading to the establishment of the first certified chimeric antigen receptor T (CAR-T) Cell Unit in Poland on the basis of the Department of Hematology and Bone Marrow Transplantation in Poznan University of Medical Sciences and first successful CAR-T therapy in Poland. During 12 months from the initial decision to establish the CAR-T Cell Unit to the application of CAR-T cell treatment in the first patient, the center had to undergo the multidisciplinary external and internal training, as well as the adaptation of multiple procedures within the Transplant Unit and Stem Cell Bank. In order to get accreditation for the implementation of CAR-T cell therapy, an initial training of the team involved in handling cellular products and patient care was organized and updated as a continuous process. The Department fulfilled the site-selection international criteria. The first patient diagnosed for refractory/relapsed DLBCL was qualified, and finally CAR-T cells were administered with successful clinical outcome
Gender and the length of time since autologous hematopoietic stem cell transplantation-What is their influence on the immune reconstitution in multiple myeloma patients?
IntroductionIn the literature there is lack of information on the influence of gender and time since autologous hematopoietic stem cell transplantation (HSCT) on the immune reconstitution in multiple myeloma (MM) patients.ObjectiveThe aim of this study was to assess the diversity of the immune reconstitution according to gender in MM patients after autologous HSCT on the day of the clinic discharge and on the 29th day after discharge, as well as to investigate the changes in the immune system in females and males after staying at home for 28 days.MethodThe studied population comprised 13 females and 13 males after autologous HSCT. On the day of the clinic discharge and on the 29th day after discharge blood samples were taken to analyse 22 immunological parameters. Statistical analysis was performed using STATISTICA 10 StatSoft Poland. For multiple comparisons, the Bonferroni correction was used.ResultsNo statistically significant differences were observed in the analysed immunological parameters between the studied females and males with MM on the day of the clinic discharge and on the 29th day after discharge. However, on the 29th day after the clinic discharge compared to the day of the clinic discharge, statistically significant differences were found in 8 immunological parameters among females and 6 immunological parameters among males.Conclusion and recommendationOur results indicate that the immune reconstitution is similar but not the same in patients of both genders. Statistically significant differences in the immune response in the studied females and males imply that gender may play a role in the immune reconstitution and that the results obtained in MM patients should be analysed separately in females and males. In order to explain the observed changes in the immune system according to gender, further research should be carried out on a larger population. This would most probably make it possible to find their clinical application
Acute Myeloid Leukemia Post Cytotoxic Therapy in Breast Cancer SurvivorsâOver 23 Years of Single Center Analysis
Background: Acute myeloid leukemia post cytotoxic therapy (AML-pCT) among breast cancer (BC) survivors represents a life-threatening complication. This study aims to assess the clinical outcomes of AML-pCT post BC. Methods: An analysis of all AML patients treated at a single hematology center (2000â2023) was performed to select patients with AML-pCT post BC. We applied the 2022 ELN criteria to define the genetic risk. Results: Among 847 AML patients, 28 were diagnosed with AML-pCT following BC. Complex karyotype (CK) occurred in 23.8% of patients. The median overall survival (OS) was 40 months. The survival outcomes were better after allogenic hematopoietic stem cell transplantation (alloHCT) treatment compared to chemotherapy alone (median OS: 47 versus 7 months, p = 0.008). Patients demonstrating CK showed lower survival compared to those without CK (2-year OS: 25.0% versus 66.2%, p = 0.0048). The multivariable Cox proportional hazards regression model indicated that treatment with alloHCT emerged as a significant factor associated with improved OS. The treatment was associated with superior OS (HR = 0.07, 95% CI = 0.01â0.86, p = 0.04). Conclusions: Patients with AML-pCT following BC were characterized with the highest frequency of adverse genetic risk profiles and demonstrated worse survival rates. AlloHCT should be performed as early as possible in such patients. The growing need for studies on inherited cancer susceptibility underscores the importance of close AML-pCT development monitoring in BC survivors
