SARS-CoV-2 infection can impact survival of patients with acute myeloid leukemia (AML). International experts recommend considering delaying or stopping AML treatment, test patients who need intensive induction and s prioritizing outpatient treatment. However there is little published evidence in AML. Objective To analyze the clinical futures and outcome of SARS-CoV-2 infection in AML patients. Methods and patients Observational multicenter study between March and May 2020; 117 patients reported from 47 Spanish centers, but 13 had no PCR or antibody test documented, finally including 104 patients from 45 hospitals. Results The median age was 68 years, men (56.7% vs 43.3%), and the median time from AML diagnosis to SARS-CoV-2 was 4 months. The mean of comorbidities was 1.2, high blood pressure (40.4%), heart disease (17.3%), diabetes (13.5%), smoking (8.8%), chronic obstructive pulmonary disease or emphysema (7.7%), renal failure (6.7%) and liver dysfunction (1.9%). Cytogenetic risk was low in 16.9%, intermediate in 57.1% and high in 26.0%; 55.7% had active disease, 39.2% complete remission and 5.1% partial response. 29.4% were off-therapy and 70.6% under antileukemic treatment at the time of SARS-CoV-2: induction chemotherapy (25.3%), hypomethylating (19.3%), clinical trial (17.0%), consolidation chemotherapy (14.8%), venetoclax (3.4%), FLT3 inhibitors (3.4%) and/or maintenance (1.1%). Overall 3.7% were newly diagnosed (no prior therapy), 77.8% had received one line of treatment, 14.8% two and 3.7% four. 15.4% had prior allogeneic transplantation. Only 4.0% of the patients were asymptomatic, while the main signs and symptoms were fever (77.8%), pneumonia (75.0%), cough (65.3%), dyspnea (52.0%), diarrhea (20.4%), nausea and/or vomiting (12.2%), rhinorrhea (10.2%) and headache (7.4%). Analytical parameters were: neutrophils 3112 cells/µL (1900-7300), lymphocytes 1090 cells/µL (1000-3000), interleukin 6 118 pg/mL (0-100), ferritin 4505 ng/mL (15-150) and D-dimer 2823 ng/mL (20-500), with liver enzymes altered in 23.9% of cases. 84.2% received specific treatment for coronavirus infection: chloroquine or hydroxychloroquine (82.2%), lopinavir/ritonavir (54.0%), corticosteroids (39.6%), azithromycin (33.0%), tocilizumab (15.8%), plasma convalescent (3.0%), clinical trial medication (3.0%), remdesivir (2.0%) and/or anakinra (1.0%). The course was mild in 14.7% (no hospitalization), moderate in 32.0% and severe in 53.3%. The implementation of intensive measures was assessed in 48.2%(14.9% admitted to the ICU and the remaining 33.3% rejected). The mean time to negativization was 20.5 days, duration of symptoms 17.6 days and the hospital stay 11.1 days. In 48.1% of the cases treatment for AML was maintained, in 26.6% delayed and in 25.3% modified due to coronavirus disease.47.5% died, establishing an association between mortality and age over 60 years (58.3% vs 36.4%, p=0.043), ≥2 lines of treatment (72.7% vs 44.3%, p=0.020), active disease (62.5% vs 29.4%, p=0.002) and pneumonia (61.2% versus 22.7%, p=0.002). Overall 47.5% overcame the infection, and in 5.0% SARS-CoV-2 genetic material was still detected at the time of analysis. A non-significant lower mortality rate was observed among: previous transplantation (45.7% vs 64.3%, p=0.19), neutrophil >1900 cells/µL (41.1% vs 60.0%, p=0.09), lymphocyte >1000 cells/µL (42.9% vs 63.6%, p = 0.09) and hydroxychloroquine/chloroquine plus azithromycin (35.3% vs 60.0%, p=0.10). Conclusions SARS-CoV-2 infection produces high mortality among AML patients. Mortality was correlated with age, active disease and pneumonia.

Background: Over the last decade there has been an improvement on the outcome of multiple myeloma (MM) patients. In patients eligible for high-dose chemotherapy and autologous stem cell transplant (ASCT), the inclusion of bortezomib in induction chemotherapy (ICT) has significantly delayed disease progression. Several studies have shown that achieving a complete response (CR) after ASCT is a predictive factor for disease control, leading to improved progression-free survival (PFS) and overall survival (OS). Aims: Assessing the impact of depth of response before and after ASCT on PFS in a population of MM patients treated with ICT including bortezomib and identifying predictive/protective factors for disease progression. Methods: Retrospective study of MM patients admitted for ASCT between January 2015 and December 2017 treated in first line with VCd (bortezomib, cyclophosphamide, and dexamethasone) or VTd (bortezomib, thalidomide and dexamethasone). Demographic (gender, age), clinical and biological variables at diagnosis were collected, as well as response obtained before and at D+100 after ASCT, and time elapsed between ASCT and disease progression. Statistical analysis was performed using STATA software (V13). Results: A total of 53 MM patients in the first line setting were included in this study. 43.4% were male; median age at diagnosis was 60 years old (IQR, 40-72). Both groups (VCd and VTd) had similar baseline characteristics. Median follow-up after induction chemotherapy was 20.6 months. PFS of patients who achieved CR or very good partial response (VGPR) post-induction was 73.7%, versus 60% in patients who achieved partial response (PR) or lower (log-rank p = 0.07). Looking at different variables that could modify the time between ASCT and disease progression, we observed that ISS stage 3 is an independent predictive factor for disease progression (HR 3.1; p = 0.014), and obtaining CR/ VGPR at D+100 post-ASCT is an independent protective factor against disease progression (HR 0.2; p = 0.004). Summary/Conclusion: Despite the relatively short follow-up period, in this population of transplant-eligible MM patients, we have demonstrated that the depth of response after induction chemotherapy (VGPR/CR) is critical for a greater PFS, and that a profound reduction in tumor burden (VGPR/CR) after ASCT allows for prolonged disease control. However, ISS stage 3 is a risk factor for disease progression regardless of the obtained response.
Introduction: Over the last few years, novel agents-based combinations have been incorporated into the treatment of MM patients, particularly in relapse setting. However, these novel combinations have been evaluated in clinical trials and patients included represent a selected population. Patients in real life are usually older with comorbidities and disabilities and not allowed to be included in the trials, so, in real setting, is expected worse outcomes and shorter survival. The information about treatment burden in real life is scarce. The aim of our study was to analyze the outcome of MM patients in the real life outside clinical trials, in terms of treatment lines in a single institution setting, and to analyze the influence of comorbidities on the treatment burden. Material and methods: Medical records of MM patients treated at Txagorritxu hospital (Spain) between 2009 and January 2017 were retrospectively evaluated with the aim of mapping the course of patients as well as to investigate the factors that influence treatment-decisions at different stages of the disease. Results: 176 patients with MM were diagnosed from jan-2009 to jan-2017. Baseline patient's characteristics are presented in Table 1. The median age at diagnosis was 71 years (range 33.2-93), main of the patients where non-transplant eligible newly diagnosed MM (NTENDMM): 114 (65%). With a median follow-up of 25 months, 90.6% of newly diagnosed MM patients transplant-eligible (TENDMM) remain alive versus 65% NTENDMM patients (p value: 0.000)(figure 1). Overall, patients received a median of 2 lines of treatment, it should be noted that 86% of patients had received 3 or less lines of treatment and only 14% of the patients could receive more than 3 lines of therapy. To better evaluate treatment burden, we focused on deceased patients. At the time of analysis, 19% of TENDMM (12 patients) and 51.4% of in NTENDMM (57 patients) has died with a median time to death of 29.6 months and 18 months to death, respectively. Median lines of therapy for death patients TENDMM was 3.5 (range 1-8), with a 75 percentile of 5 lines of therapy, by contrast, death NTENDMM patients received a median of 2 lines of therapy (range: 1-6), with an 80 percentile of 3 lines of therapy (figure 2). In order to evaluate the influence of comorbidities in treatment burden for NTENDMM patients, CIRS score was estimated retrospectively. Median CIRS score was 5.5 (1-19). CIRS scale did not predict progression free survival (PFS) among the different groups: CIRS <4: 23.4 months; CIRS4-8: 25.1 months and CIRS> 8: 30.6 months (p: 0.819), however, interestingly CIRS scale predicted overall survival (OS): CIRS <4: 48 moths; CIRS4-8: 50.8 months and CIRS> 8: 12.3 months, (p: 0.012) (figure 2). Analyzing treatment burden for each CIRS score group 63% of patients with CIRS> 8 received only one line of treatment before death, compared to 39.5% and 37.5% of patients with CIRS4-8 and CIRS <4, respectively. Conclusion: Although the impressive progress in the management of relapse/refractory MM patients in recent years, half of the patients, particularly those not suitable to received an autologous transplant, will be able to received only 2 lines of treatment before dying. In fact, an adequate comorbidity assessment could select patients that will only need only one line of treatment. To the best of our known, this is the first study that correlate treatment burden according to comorbidities at diagnostic. This study could guide strategies adapted according to the comorbidity of the patients. Disclosures No relevant conflicts of interest to declare.
