ABSTRACT

Background: Patients with chronic lymphocytic leukemia (CLL) may be more susceptible to COVID-19 related poor outcomes, including thrombosis and death, due to the advanced age, the presence of comorbidities, and the disease and treatment-related immune deficiency. In this retrospective multicenter study, conducted by ERIC, the European Research Initiative on CLL, we assessed the risk of thrombosis and bleeding in patients with CLL affected by severe COVID-19. Methods: : The study included patients from 79 centers across 22 countries. Data collection was conducted between April and May 2021. Results: : A total of 793 patients from 79 centers were included in the study with 593 being hospitalized (74.8%). Among these, 518 were defined as having severe COVID: 162 were admitted to the ICU while 356 received oxygen supplementation outside the ICU. Most patients (90%) were receiving thromboprophylaxis. During COVID-19 treatment, 8.8% developed a thromboembolic event, while 4.8% experienced bleeding. Thrombosis developed in 20.5% of patients who were not receiving thromboprophylaxis, but only in 8.1% of patients who were on thromboprophylaxis. Bleeding episodes were more frequent in patients receiving intermediate/therapeutic versus prophylactic doses of low-molecular-weight heparin (LWMH) (11.1% vs. 4.2%, respectively) and in elderly. In multivariate analysis, peak D-dimer level was a poor prognostic factor for thrombosis occurrence (OR=1.020, 95%CI 1.006‒1.033), while thromboprophylaxis use was protective (OR=0.194, 95%CI 0.061‒0.614). Age and LMWH intermediate/therapeutic dose administration were prognostic factors in multivariate model for bleeding (OR=1.055, 95%CI 1.013-1.103 and OR=2.490, 95%CI 1.044-5.935, respectively). Conclusions: : Patients with CLL affected by severe COVID-19 are at a high risk of thrombosis if thromboprophylaxis is not used, but also at increased risk of bleeding under the LMWH intermediate/therapeutic dose administration.

ABSTRACT

Patients with acute myeloid leukemia (AML) are at high risk of mortality from coronavirus disease 2019 (COVID-19). The optimal management of AML patients with COVID-19 has not been established. Our multicenter study included 388 adult AML patients with COVID-19 diagnosis between February 2020 and October 2021. The vast majority were receiving or had received AML treatment in the prior 3 months. COVID-19 was severe in 41.2% and critical in 21.1% of cases. The chemotherapeutic schedule was modified in 174 patients (44.8%), delayed in 68 and permanently discontinued in 106. After a median follow-up of 325 days, 180 patients (46.4%) had died. Death was attributed to COVID-19 (43.3%), AML (26.1%) or to a combination of both (26.7%). Active disease, older age, and treatment discontinuation were associated with death, whereas AML treatment delay was protective. Seventy-nine patients had a simultaneous AML and COVID-19 diagnosis, with an improved survival when AML treatment could be delayed. Patients with COVID-19 diagnosis between January and August 2020 had a significantly lower survival. COVID-19 in AML patients was associated with a high mortality rate and modifications of therapeutic algorithms. The best approach to improve survival was to delay AML treatment.

ABSTRACT

Patients with chronic lymphocytic leukemia (CLL) may be more susceptible to Coronavirus disease 2019 (COVID-19) due to age, disease, and treatment-related immunosuppression. We aimed to assess risk factors of outcome and elucidate the impact of CLL-directed treatments on the course of COVID-19. We conducted a retrospective, international study, collectively including 941 patients with CLL and confirmed COVID-19. Data from the beginning of the pandemic until March 16, 2021, were collected from 91 centers. The risk factors of case fatality rate (CFR), disease severity, and overall survival (OS) were investigated. OS analysis was restricted to patients with severe COVID-19 (definition: hospitalization with need of oxygen or admission into an intensive care unit). CFR in patients with severe COVID-19 was 38.4%. OS was inferior for patients in all treatment categories compared to untreated (p < 0.001). Untreated patients had a lower risk of death (HR = 0.54, 95% CI:0.41-0.72). The risk of death was higher for older patients and those suffering from cardiac failure (HR = 1.03, 95% CI:1.02-1.04; HR = 1.79, 95% CI:1.04-3.07, respectively). Age, CLL-directed treatment, and cardiac failure were significant risk factors of OS. Untreated patients had a better chance of survival than those on treatment or recently treated.

ABSTRACT

INTRODUCTIONCoronavirus disease 2019 (COVID-19) caused by SARS-CoV2 virus is thought to be more severe in patients with prior hematological diseases. There is evidence suggesting that hematological patients are particularly vulnerable and have a higher risk of developing severe events, with higher mortality rate than general population. However, the available data are limited, and prognostic factors at admission still remain unclear. With this background, our aims were to analyze the impact of hematological diseases and their therapy on the COVID-19 severity and to identify clinical and biological risk factors to predict the outcome in these patients.METHODSWe carried out a multicenter retrospective observational study with data collection from 19 Spanish centers. A total of 491 patients with hematological diseases who developed COVID-19 (HEMATOCOVID patients) from March 8th to June 9th were included in the study. Clinical and biological data were collected at the time of emergency room assistance or hospital admission. For statistical analysis, chi-square test and Mann-Whitney U-test were used to identify differences between groups. The effects of multiple predictor variables on COVID-19 outcomes were assessed by logistic binary regression.RESULTSThe geographic distribution of the studied HEMATOCOVID patients was similar to the national geographic spread of the COVID-19 (Figure 1). Most patients (94,3%) were confirmed cases of COVID-19 with a positive result on SARS-CoV2 RT-PCR on a nasopharyngeal swab or serologic testing, and 15% were nosocomial infections. The mean age was 71 years with 57% males, and 70% had at least one associated comorbidity. The most frequent hematological diseases among COVID-19 patients were Lymphoid Malignancies (53,8%), and 51,7% of patients were on active treatment. Most common symptoms were fever (59%), cough (54%) and dyspnea (46%), with associated pneumonia in 70% of cases. Hospital admission was required in 89% of patients and 6,3% were admitted to intensive care units.Mortality rate was about 36%. Non-survival patients were older and had a higher Charlson comorbidity index and ECOG performance status. Furthermore, patients with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS), and those with an active or progressive hematological disease at the diagnosis of COVID-19 had higher mortality. Patients who had undergone hematopoietic stem cell transplantation (autologous, allogeneic, and both) had better outcomes. Other factors such as low lymphocyte and platelets counts, or high lactate dehydrogenase (LDH), C-reactive protein (CRP) and procalcitonin values were also associated with poorer outcomes (Table 1). In addition, COVID-19 therapy had no impact on survival, except for corticosteroids, that correlated with a negative impact (p <0,001) probably because they were not administrated to patients with less severe COVID-19. Multivariate regression analysis showed the following risk factors for death: age >70 years, ECOG ≥2, absolute lymphocyte count ≤0.6·109/L, platelet count ≤40·109/L, high LDH (higher than upper normal limit) and CRP >11 mg/dL (Table 2).CONCLUSIONSSARS-CoV2 infection causes more severe disease and higher mortality rates in hematological patients, especially those with AML/MDS or active/progression status disease. In addition, advanced age, co-morbidities, poor performance status, low lymphocyte and platelet counts and high LDH and CRP at admission are associated with poorer survival. This worse disease evolution could be explained by the immunosuppression state induced by underlying disease and treatments received. These particular features should be taken into account for a population that is highly exposed to SARS-CoV2 contagion due to high number of hospital visits for treatment.

ABSTRACT

Introduction: Patients (pts) with CLL may be at particular risk of severe COVID-19 given advanced age and immune dysregulation. Two large series with limited follow-up have reported outcomes for pts with CLL and COVID-19 (Scarfò, et al. Leukemia 2020;Mato, et al. Blood 2020). To provide maximal clarity on outcomes for pts with CLL and COVID-19, we partnered in a worldwide effort to describe the clinical experience and validate predictors of survival, including potential treatment effects.Methods: This international collaboration represents a partnership between investigators at 141 centers. Data are presented in two cohorts. Cohort 1 (Co1) includes pts captured through efforts by European Research Initiative on CLL (ERIC), Italian CAMPUS CLL Program, and Grupo Español de Leucemia Linfática Crónica. The validation cohort, Cohort 2 (Co2), includes pts from US (66%), UK (23%), EU (7%), and other countries (4%). There is no overlap in cases between cohorts.CLL pts were included if COVID-19 was diagnosed by PCR detection of SARS-CoV-2 and they required inpatient hospitalization. Data were collected retrospectively 2/2020 - 5/2020 using standardized case report forms. Baseline characteristics, preexisting comorbidities (including cumulative illness rating scale (CIRS) score ≥6 vs. <6), CLL treatment history, details regarding COVID-19 course, management, and therapy, and vital status were collected.The primary endpoint of this study was to estimate the case fatality rate (CFR), defined as the proportion of pts who died among all pts hospitalized with COVID-19. Chi-squared test was used to compare frequencies;univariable and multivariable analyses utilized Cox regression. Predictors of inferior OS in both Co1 and Co2 were included in multivariable analyses. Kaplan-Meier method was used to estimate overall survival (OS) from time of COVID-19 diagnosis (dx).Results: 411 hospitalized, COVID-19 positive CLL pts were analyzed (Co1 n=281, Co2 n=130). Table 1 describes baseline characteristics. At COVID-19 dx, median age was 72 in Co1 (range 37-94) and 68 in Co2 (range 41-98);31% (Co1) and 45% (Co2) had CIRS ≥6. In Co1, 48% were treatment-naïve and 26% were receiving CLL-directed therapy at COVID-19 dx (66% BTKi ± anti-CD20, 19% Venetoclax ± anti-CD20, 9.6% chemo/chemoimmunotherapy (CIT), 1.4% PI3Ki, 4% other). In Co2, 36% were never treated and 49% were receiving CLL-directed therapy (65% BTKi ± anti-CD20, 19% Venetoclax ± anti-CD20, 9.4% multi-novel agent combinations, 1.6% CIT, 1.6% PI3Ki, 1.6% anti-CD20 monotherapy, 1.6% other). Most pts receiving CLL-directed therapy had it held at COVID-19 diagnosis (93% in Co1 and 81% in Co2).Frequency of most COVID-19 symptoms/laboratory abnormalities were similar in the two cohorts including fever (88% in both), lymphocytosis (ALC ≥30 x 109/L;27% vs. 21%), and lymphocytopenia (ALC <1.0 x 109/L;18% vs. 28%), while others varied between Co1 and Co2 (p<0.0001), including cough (61% vs. 93%), dyspnea (60% vs. 84%), fatigue (13% vs. 77%).Median follow-up was 24 days (range 2-86) in Co1 and 17 days (1-43) in Co2. CFRs were similar in Co1 and Co2, 30% and 34% (p=0.45). 54% and 43% were discharged while 16% and 23% remained admitted at last follow-up in Co1 and Co2, respectively. The proportion of pts requiring supplemental oxygen was similar (89% vs. 92%) while rate of ICU admission was higher in Co2 (20% vs. 48%, p<0.0001). Figure 1 depicts OS in each cohort. Univariable analyses demonstrated that age and CIRS ≥6 significantly predicted inferior OS in both cohorts, while only age remained an independent predictor of inferior OS in multivariable analyses (Table 2). Prior treatment for CLL (vs. observation) predicted inferior OS in Co1 but not Co2.Conclusions : In the largest cancer dx-specific cohort reported, pts with CLL hospitalized for COVID-19 had a CFR of 30-34%. Advanced patient age at COVID-19 diagnosis was an independent predictor of OS in two large cohorts. This CFR will serve as a benchmark for mortality for future outcomes studies, including thera eutic interventions for COVID-19 in this population. The effect of CLL treatment on OS was inconsistent across cohorts;COVID-19 may be severe regardless of treatment status. While there were no significant differences in distribution of current lines of therapy between cohorts, prior chemo exposure was more common in Co1 vs. Co2, which may account for difference in OS. Extended follow-up will be presented.

ABSTRACT

Patients with cancer are poorly represented in coronavirus disease 2019 (COVID-19) series, and heterogeneous series concerning hematology patients have been published. This study aimed to analyze the impact of COVID-19 in patients with lymphoma. We present a multicenter retrospective study from 19 centers in Madrid, Spain, evaluating risk factors for mortality in adult patients with COVID-19 and lymphoma. About 177 patients (55.9% male) were included with a median follow-up of 27 days and a median age of 70 years. At the time of COVID-19 diagnosis, 49.7% of patients were on active treatment. The overall mortality rate was 34.5%. Age >70 years, confusion, urea concentration, respiratory rate, blood pressure, and age >65 score ≥2, heart disease, and chronic kidney disease were associated with higher mortality risk (P < 0.05). Active disease significantly increased the risk of death (hazard ratio, 2.43; 95% confidence interval, 1.23-4.77; P = 0.01). However, active treatment did not modify mortality risk and no differences were found between the different therapeutic regimens. The persistence of severe acute respiratory syndrome coronavirus 2-positive polymerase chain reaction after week 6 was significantly associated with mortality (54.5% versus 1.4%; P < 0.001). We confirm an increased mortality compared with the general population. In view of our results, any interruption or delay in the start of treatment should be questioned given that active treatment has not been demonstrated to increase mortality risk and that achieving disease remission could lead to better outcomes.

ABSTRACT

The spectrum of COVID-19 infection includes acute respiratory distress syndrome (ARDS) and macrophage activation syndrome (MAS), although the histological basis for these disorders has not been thoroughly explored. Post-mortem pulmonary and bone marrow biopsies were performed in 33 patients. Samples were studied with a combination of morphological and immunohistochemical techniques. Bone marrow studies were also performed in three living patients. Bone marrow post-mortem studies showed striking lesions of histiocytic hyperplasia with hemophagocytosis (HHH) in most (16/17) cases. This was also observed in three alive patients, where it mimicked the changes observed in hemophagocytic histiocytosis. Pulmonary changes included a combination of diffuse alveolar damage with fibrinous microthrombi predominantly involving small vessels, in particular the alveolar capillary. These findings were associated with the analytical and clinical symptoms, which helps us understand the respiratory insufficiency and reveal the histological substrate for the macrophage activation syndrome-like exhibited by these patients. Our results confirm that COVID-19 infection triggers a systemic immune-inflammatory disease and allow specific therapies to be proposed.

ABSTRACT

We are facing a pandemic that is going to affect a significant part of the population. At the end of April in the world there are about 3,000,000 cases, with 205,000 deaths and 860,000 patients recovered. The response to this pandemic has in many cases led to a significant change in the daily work of caring for cancer patients, the good results of which depend largely on time-adjusted protocols and multidisciplinary treatments. We present a review of local, surgical and radiotherapy treatment together with authors’ recommendations made from personal experience on ways to act in the diagnosis and surgical treatment of breast cancer during the COVID-19 pandemic. The multidisciplinary Breast Committees must continue to meet weekly in videoconference format. All surgical actions and irradiations must be carried out with maximum safety for both the patients and the participating teams. Hypofractionation in radiation therapy should be the standard treatment. Sometimes it is recommended to apply a primary systemic treatment or even a primary irradiation. Great coordination between the surgical and oncology teams, both medical and radiotherapeutic, is essential.
