RESUMEN
INTRODUCTION: Elderly acute myeloid leukemia (AML) patients with poor-risk cytogenetics have a poor outcome with intensive chemotherapy (IC). While Venetoclax (VEN) has changed the outcomes of elderly unfit patients treatment, it is unknown whether it could be effective in poor-risk cytogenetics 60-75 years old patients. MATERIALS AND METHODS: We included 60-75-year-old AML patients eligible to allogenic stem cell transplantation (allo-SCT) treated with VEN (combined with azacitidine or with Cladribin and Aracytine) at Institut Paoli Calmettes, between 2020 and 2023 and compared this cohort with patients treated by IC between 2010 and 2019. RESULTS: Twenty six patients were treated with VEN (17 in combination with azacitidine and 9 with Cladribin and Aracytine) and 90 were treated with IC. Thirteen patients (50%) had a TP53 mutation. The median time for leucocyte and platelet counts recovery was 26 days (range 0-103) and 26 days (range, 0-63). The median duration of the first hospitalization was 32 days (ranges, 7-79). The composite response rate was 69% (CR = 50%, CRi = 4%, MLFS = 15%). Allo-SCT could be performed in 42% of cases. Median overall survival (OS) was 7.9 months (20.9 months in the group of patients who transitioned to allo-SCT). We found no difference with the historical cohort of patients treated with IC except a trend toward less lower and upper tract gastro-intestinal (GI) tract infections in the VEN group (respectively 8% vs 26%, p = .06; and 0% vs. 13% p = .06). CONCLUSION: VEN-based treatment was found to be effective in high risk AML can be considered as an alternative to IC in patients aged 60-75 with adverse cytogenetics.
RESUMEN
Hepatic dysfunction (HD) is common in patients with haematological malignancies. Hepatic haemophagocytosis (HH) was detected in >50% of liver biopsies taken when HD remained unresolved after standard examination. We aimed to explore the contribution of liver biopsy in patients with both haematological malignancies and HD, describe the population of patients with HH, assess the prognostic impact of HH, and investigate haemophagocytic syndrome diagnostic score (HScore) utility in patients with HH. Between 2016 and 2019, 116 consecutive liver biopsies (76 transjugular, 40 percutaneous) were taken in 110 patients with haematological malignancy and HD (hyperbilirubinaemia, elevated transaminases, and/or cholestasis) and without a clear diagnosis. Liver biopsies were safe and diagnostically efficient. Predominant diagnoses included: HH (56%), graft-versus-host disease (55%), associated infections (24%), sinusoidal obstruction syndrome (15%), and tumoral infiltration (8%). Of patients, 35% were critically ill and 74% were allogeneic haematopoietic stem cell transplantation recipients, while 1-year overall survival (OS) was 35% with HH versus 58% without HH (p = 0.026). The 1-year OS was 24% with a HScore of ≥169 versus 50% with a HScore of <169 (p = 0.019). Liver biopsies are feasible in and contribute significantly to haematology patients with HD. HH occurred frequently and was associated with a poor prognosis. Combined with liver biopsy, the HScore may be helpful in refining haemophagocytic syndrome diagnosis.

The aim of this study was to characterize a large series of 154 patients with acute promyelocytic leukemia (median age, 53 years; range, 18-90 years) and evaluate real-life outcome after up-front treatment with arsenic trioxide and all-trans retinoic acid. All patients were included in the prospective NAPOLEON registry (NCT02192619) between 2013 and 2019. The acute promyelocytic leukemia was de novo in 91% (n=140) and therapy-related in 9% (n=14); 13% (n=20) of the patients were older than 70 years. At diagnosis bleeding/hemorrhage was present in 38% and thrombosis in 3%. Complete remission was achieved in 152 patients (99%), whereas two patients (1%) experienced induction death within 18 days after starting therapy. With a median follow-up of 1.99 years (95% confidence interval: 1.61-2.30 years) 1-year and 2-year overall survival rates were 97% (95% confidence interval: 94-100%) and 95% (95% confidence interval: 91-99%), respectively. Age above 70 years was associated with a significantly shorter overall survival (P<0.001) compared to that of younger patients. So far no relapses have been observed. Six patients (4%) died in complete remission at a median of 0.95 years after diagnosis (range, 0.18-2.38 years). Our data confirm the efficiency and durability of arsenic trioxide and all-trans retinoic acid therapy in the primary management of adults with low-/intermediate-risk acute promyelocytic leukemia in the real-life setting, irrespective of age.

Haploidentical stem cell transplantation (haplo-SCT) with post-transplant cyclophosphamide (PT-Cy) is an alternative treatment for acute myeloid leukemia (AML) patients who lack HLA-matched donors. Relapse after haplo-SCT remains a major concern, especially after nonmyeloablative conditioning regimens. Promising results were reported for TBF-based conditioning regimens (thiotepa, busulfan, and fludarabine) in patients transplanted from different categories of donors and for various disease types but not specifically in PT-Cy haplo-SCT for AML. Here we evaluate the outcome of 100 AML patients who received haplo-SCT with PT-Cy after TBF conditioning regimens (reduced-intensity conditioning, nâ¯=â¯77; myeloablative conditioning, nâ¯=â¯23) in 2 transplant programs. Cumulative incidences of grades III to IV acute and moderate or severe chronic graft-versus-host disease (GVHD) were 7% and 14%, respectively. NRM at 2 years was 28%, significantly influenced by disease status at haplo-SCT (first complete response [CR1] versus advanced AML: 16% versus 38%, Pâ¯=â¯.016) but not by conditioning intensity or age. The cumulative incidences of relapse at 2 years were 17% and 24% in CR1 and advanced AML, respectively (not significant). Progression-free survival, overall survival, and GVHD and relapse-free survival at 2 years were 67%, 71%, and 49% in CR1 patients, respectively, whereas comparative values in patients with advanced disease were 37%, 41%, and 32%. Our study suggests that TBF conditioning for PT-Cy haplo-SCT is safe and effective for AML patients in CR1. In patients with more advanced disease, the relatively low incidence of relapse seems counterbalanced by a high nonrelapse mortality, underlining the need for alternative strategies to decrease relapse risk, without increasing the intensity of conditioning regimen.

Haploidentical related donor (HRD) allogeneic hematopoietic stem cell transplantation (allo-HSCT) was developed as a valid option for the treatment of acute myeloid leukemia (AML) in the absence of a matched donor. However, many investigators are reluctant to consider the use of this alternative in elderly patients, anticipating high morbidity. Here, we report a single-center comparison of HRD versus matched sibling donor (MSD) and unrelated donor (UD) allo-HSCT for patients with AML aged ≥60 years. Ninety-four patients (MSD: n = 31; UD: n = 30; HRD: n = 33) were analyzed. The median age was 65 (range, 60 to 73) years. We observed a higher cumulative incidence of grade 3 to 4 acute graft-versus-host disease (GVHD) after UD allo-HSCT (MSD versus UD versus HRD: 3% versus 33% versus 6%, respectively; P = .006). Two-year cumulative incidence of moderate or severe chronic GVHD was 17%, 27%, and 16% in the MSD, UD, and HRD groups, respectively (P = .487). No difference was observed in the 2-year cumulative incidence of relapse or nonrelapse mortality (NRM) (relapse: MSD versus UD versus HRD: 32% versus 25% versus 25%, respectively; P = .411; NRM: MSD versus UD versus HRD: 19% versus 27% versus 24%, respectively; P = .709). At 2 years, progression-free survival, overall survival, and GVHD- and relapse-free survival were 48%, 50%, and 39%, respectively, in the MSD group; 48%, 51%, and 23%, respectively, in the UD group; and 50%, 52%, and 32%, respectively, in the HRD group, without statistically significant differences between the groups. We conclude that HRD allo-HSCT is highly feasible and no less efficient than MSD or UD allo-HSCT in patients with AML aged ≥60 years. Thus, the absence of a HLA-identical donor should not limit the consideration of allo-HSCT for the treatment of AML.

Acute myeloid leukemias secondary (sAML) to myeloproliferative neoplasms (MPN) have variable clinical courses and outcomes, but remain almost always fatal. Large cohorts of sAML to MPN are difficult to obtain and there is very little scientific literature or prospective trials for determining robust prognostic markers and efficient treatments. We analyzed event-free survival (EFS) and overall survival (OS) of 73 patients with MPN who progressed to sAML, based on their epidemiological characteristics, the preexisting MPN, the different treatments received, the different prognostic groups and the responses achieved according to the ELN, and their mutational status determined by next-generation DNA sequencing (NGS). For 24 patients, we were able to do a comparative NGS analysis at both MPN and sAML phase. After acute transformation EFS and OS were respectively of 2.9 months (range: 0-48.1) and 4.7 months (range: 0.1-58.8). No difference in EFS or OS regarding the previous MPN, the ELN2017 prognostic classification, the first-line therapy or the response was found. After univariate analysis, three genes, TP53, SRSF2 and TET2, impacted pejoratively sAML prognosis at sAML time. In multivariate analysis, TP53 (P = .0001), TET2 (P = .011) and SRSF2 (P = .018) remained independent prognostic factors. Time to sAML transformation was shorter in SRSF2-mutated patients (51.2 months, range: 14.7-98) than in SRSF2-unmutated patients (133.8 months, range: 12.6-411.2) (P < .001). Conventional clinical factors (age, karyotype, ELN2017 prognostic classification, treatments received, treatments response, Allo-SCT ) failed to predict the patients' outcome. Only the mutational status appeared relevant to predict patients' prognosis at sAML phase.

We report the case of a patient with a history of Epstein-Barr virus-positive large B-cell lymphoma, who relapsed with an angioimmunoblastic T-cell lymphoma (AITL) associated with a chronic myelomonocytic leukaemia (CMML). We performed targeted next-generation sequencing on CMML and AITL DNA, which revealed mutations of TET2, DNMT3A, SRSF2, NRAS and IDH1, thus confirming that the spectrum of AITL mutations share similarities with myeloid disorders. The frequencies of TET2/DNMT3A and SRSF2 variants could support the hypothesis that TET2/DNMT3A mutations occurred in an early progenitor cell, which later progressed to both the AITL and CMML clones. Treatment with 5-azacytidine led to the complete remission of both diseases. Thus, targeting DNA methylation abnormalities in AITL may be an alternative strategy to chemotherapy.

PURPOSE: Prophylactic platelet transfusions (PT) aim to reduce bleeding. We assessed whether restrictive PT compared to prophylactic strategy could apply in ICU. MATERIAL AND METHODS: We conducted a retrospective monocentric study including patients >18 yo with haematological malignancy admitted to the ICU with thrombocytopenia <20 G/L between 2018 and 2021. Patients were classified in 2 groups according transfusion strategy applied during the first 3 days: prophylactic or restrictive transfusion. RESULTS: 180 patients were included, 87 and 93 in the restrictive and prophylactic groups respectively. After propensity-score analysis, 2 groups of 54 matched patients were analyzed. Restrictive strategy led to a significant reduction in PT with incidence rate for 100-ICU-patients-days of 34.9 and 49.9, incidence rate ratio = 0.699 [0.5-0.9], p = 0.006, representing a 31% decrease. Decreased PT persisted until day 28 with platelet concentrates transfusions-free days at day 28 of 21 [13-25] and 16.5 [10.2-21] in the 2 groups (p = 0.04). Restrictive strategy did not result in higher grade ≥ 2 bleeding. Transfusion efficiency was low with similar number of days with platelet <10 or < 20 G/L regardless of strategy. Platelet transfusion strategy was not associated with 28-day mortality. Platelet nadir <5G/L was associated with day-28 mortality with HR = 1.882 [1.011-3.055], p = 0.046. CONCLUSION: A restrictive PT strategy appears feasible in the ICU.

OBJECTIVES: Acute myeloid leukaemia (AML) and high-risk myelodysplastic syndromes (MDS) are often treated with intensive chemotherapy followed by allogeneic haematopoietic stem cell transplantation (allo-HSCT). The pretransplant treatment results in a general deterioration of the patient's health and quality of life. Furthermore, allo-HSCT can be responsible for significant toxicity with risks of graft-versus-host disease (GvHD). Developing strategies to prevent physical deconditioning, undernutrition and psychological distress could help maintain a satisfactory general state of health before transplantation and thus limit these deleterious effects. This protocol evaluates the feasibility and adherence to a personalised prehabilitation programme, which can be modulated and assisted by connected objects, provided from the diagnosis to the allo-HSCT. METHODS AND ANALYSIS: This multicentre interventional study will include 50 patients treated for AML or high-risk MDS with intensive chemotherapy and eligible for allo-HSCT. The intervention consists of a coached, supervised or self-directed physical activity programme, organised during the hospitalisation phases and periods at home. At the same time, patients will receive a weekly dietary follow-up. The whole intervention is controlled and modulated through the use of a dedicated application and connected objects allowing adaptation and individualisation. The rate of participation in the prescribed physical activity sessions will assess the feasibility of this study. In addition, the evolution of physical capacities (Short Physical Performance Battery, grip and quadriceps strengths), psychosocial parameters (Functional Assessment of Cancer Therapy - Leukaemia, Functional Assessment of Cancer Therapy - Fatigue, subjective well-being, Hospital Anxiety and Depression Scale, self-efficacy, Coach-Athlete Relationship Questionnaire, interviews) and clinical status (weight, lean body mass, survival rate, number of infections, days of hospitalisation, GvHD) will be evaluated. ETHICS AND DISSEMINATION: The study procedures have been approved by the National Ethics Committee (21.00223.000003). Consent is given in person by each participant. The information collected on the participants contains only a non-identifiable study identifier. The results of this protocol will be published in a scientific paper and communicated to the medical staff of the medical centre. TRIAL REGISTRATION NUMBER: NCT03595787.

Mutations in spliceosome genes (SRSF2, SF3B1, U2AF1, ZRSR2) correlate with inferior outcomes in patients treated with intensive chemotherapy for Acute Myeloid Leukemia. However, their prognostic impact in patients treated with less intensive protocols is not well known. This study aimed to evaluate the impact of Spliceosome mutations in patients treated with Venetoclax and Azacitidine for newly diagnosed AML. 117 patients treated in 3 different hospitals were included in the analysis. 34 harbored a mutation in at least one of the spliceosome genes (splice-mut cohort). K/NRAS mutations were more frequent in the splice-mut cohort (47% vs 19%, p=0.0022). Response rates did not differ between splice-mut and splice-wt cohorts. With a median follow-up of 15 months, splice mutations were associated with a lower 18-month LFS (p=0.0045). When analyzing splice mutations separately, we found SRSF2 mutations to be associated with poorer outcomes (p=0.034 and p=0.037 for OS and LFS respectively). This negative prognostic impact remained true in our multivariate analysis. We believe this finding should warrant further studies aimed at overcoming this negative impact.

It has been reported that chronic graft-versus-host disease (cGVHD) is associated with significant morbidity and mortality after allogeneic stem cell transplantation (allo-SCT). The risk of relapse is generally reduced when cGVHD is present, but prognosis may be affected by increased toxicity and/or risk of infection associated with immunosuppressive treatment (IST). We performed a longitudinal data analysis of cGVHD, including the evolution of cGVHD itself over time in response to IST, in a single-center cohort of 313 consecutive patients undergoing allo-SCT. We found that lack of sustained response without withdrawal of IST within 6 months of cGVHD development was associated with higher transplantation-related mortality (hazard ratio, 2.32; 95% confidence interval, 1.24-4.33) compared with cGVHD-free patients. Conversely, response conferred better overall survival (hazard ratio, 0.42; 95% confidence interval, 0.18-0.95). Our analytical approach allowed us to integrate the evolution of cGVHD in a predictive model of transplantation outcome; notably, remission associated with permanent discontinuation of IST within the first 6 months from the occurrence of cGVHD seemed to correlate most closely with final outcome. Further confirmation from larger studies is needed.

BACKGROUND: Acute respiratory failure (ARF) is the leading cause of intensive care unit (ICU) admission in patients with Acute Myeloid Leukemia (AML) and data on prognostic factors affecting short-term outcome are needed. METHODS: This is a post-hoc analysis of a multicenter, international prospective cohort study on immunocompromised patients with ARF admitted to ICU. We evaluated hospital mortality and associated risk factors in patients with AML and ARF; secondly, we aimed to define specific subgroups within our study population through a cluster analysis. RESULTS: Overall, 201 of 1611 immunocompromised patients with ARF had AML and were included in the analysis. Hospital mortality was 46.8%. Variables independently associated with mortality were ECOG performance status ≥ 2 (OR = 2.79, p = 0.04), cough (OR = 2.94, p = 0.034), use of vasopressors (OR = 2.79, p = 0.044), leukemia-specific pulmonary involvement [namely leukostasis, pulmonary infiltration by blasts or acute lysis pneumopathy (OR = 4.76, p = 0.011)] and liver SOFA score (OR = 1.85, p = 0.014). Focal alveolar chest X-ray pattern was associated with survival (OR = 0.13, p = 0.001). We identified 3 clusters, that we named on the basis of the most frequently clinical, biological and radiological features found in each cluster: a "leukemic cluster", with high-risk AML patients with isolated, milder ARF; a "pulmonary cluster", consisting of symptomatic, highly oxygen-requiring, severe ARF with diffuse radiological findings in heavily immunocompromised patients; a clinical "inflammatory cluster", including patients with multi-organ failures in addition to ARF. When included in the multivariate analysis, cluster 2 and 3 were independently associated with hospital mortality. CONCLUSIONS: Among AML patients with ARF, factors associated with a worse outcome are related to patient's background (performance status, leukemic pulmonary involvement), symptoms, radiological findings, the need for vasopressors and the liver SOFA score. We identified three specific ARF syndromes in AML patients, which showed a prognostic significance and could guide clinicians to optimize management strategies.
RESUMEN
BACKGROUND: High-flow nasal cannula (HFNC) is increasingly used in critically ill cancer patients with acute respiratory failure (ARF) to avoid mechanical ventilation (MV). The objective was to assess prognostic factors associated with mortality in ICU cancer patients requiring MV after HFNC failure, and to identify predictive factors of intubation. METHODS: We conducted a retrospective study from 2012-2016 in a cancer referral center. All consecutive onco-hematology adult patients admitted to the ICU treated with HFNC were included. HFNC failure was defined by intubation requirement. RESULTS: 202 patients were included, 104 successfully treated with HFNC and 98 requiring intubation. ICU and hospital mortality rates were 26.2% (n = 53) and 42.1% (n = 85) respectively, and 53.1% (n = 52) and 68.4% (n = 67) in patients requiring MV. Multivariate analysis identified 4 prognostic factors of hospital mortality after HFNC failure: complete/partial remission (OR = 0.2, 95%CI = 0.04-0.98, p<0.001) compared to patients with refractory/relapse disease (OR = 3.73, 95%CI = 1.08-12.86), intubation after day 3 (OR = 7.78, 95%CI = 1.44-41.96), number of pulmonary quadrants involved on chest X-ray (OR = 1.93, 95%CI = 1.14-3.26, p = 0.01) and SAPSII at ICU admission (OR = 1.06, 95%CI = 1-1.12, p = 0.019). Predictive factors of intubation were the absence of sepsis (sHR = 0.32, 95%CI = 0.12-0.74, p = 0.0087), Sp02<95% 15 minutes after HFNC initiation (sHR = 2.05, 95%CI = 1.32-3.18, p = 0.0014), number of quadrants on X-ray (sHR = 1.73, 95%CI = 1.46-2.06, p<0.001), Fi02>60% at HFNC initiation (sHR = 3.12, 95%CI = 2.06-4.74, p<0.001) and SAPSII at ICU admission (sHR = 1.03, 95%CI = 1.02-1.05, p<0.01). CONCLUSION: Duration of HFNC may be predictive of an excess mortality in ARF cancer patients. Early warning scores to predict HFNC failure are needed to identify patients who would benefit from early intubation.

Twenty percent of allogenic hematopoietic stem cell transplantation (allo-HSCT) patients require intensive care unit (ICU) admission. Feasibility and long-term consequences of cyclosporine graft-versus-host disease (GVHD) prophylaxis withdrawal in the ICU are unknown. To assess the impact of cyclosporine prophylaxis withdrawal in critically ill allo-HSCT patients admitted to the ICU on GVHD incidence and to evaluate 6-month overall survival according to cyclosporine withdrawal and GVHD occurrence. From 2010 to 2020, 101 critically ill allo-HSCT patients admitted to the ICU in our institution were included. All received cyclosporine as GVHD prophylaxis. None of them had GVHD at ICU admission. Patients were admitted in the ICU after a median time of 11 days (5.5-18) after allo-HSCT. ICU, hospital mortality, and 6-month mortality were 43.6%, 56.4%, and 59.4%, respectively. Cyclosporine was withdrawn for 52 and continued for 49 patients in the ICU. A total of 38.6% (n = 39) developed secondarily acute GVHD (aGVHD) after a median of 28 days (15-40) after cyclosporine was discontinued. In 74.4% (n = 29) of cases, patients in the hematology ward developed aGVHD after ICU discharge. Cyclosporine dosages were similar in both groups. Factors independently associated with aGVHD occurrence in multivariate analysis were cyclosporine withdrawal in the ICU (subdistribution hazard ratios [sHR] = 2.04, 95% confidence interval [CI] = 1.02-4.1, P = .044), renal replacement therapy (RRT) (sHR = 0.43, 95% CI = 0.19-0.9, P = .03) and fungal prophylaxis (sHR = 2.62, 95% CI = 1.35-5.07, P = .004). Cyclosporine withdrawal in the ICU was associated with poorer 6-month overall survival (OS) (HR = 1.96, 95% CI = 1.16-3.33, P = .012), but after adjusting on severity (simplified acute physiology score, vasopressors, mechanical ventilation and RRT requirement), 6-month OS did not differ (HR = 1.35, 95% CI = 0.76-2.42, P = .30). GVHD occurrence after ICU stay was significantly associated with better 6-month OS in unadjusted (HR = 0.53, 95% CI = 0.31-0.90, P = .02) and severity-adjusted analysis (HR = 0.54, 95% CI = 0.31-0.93, P = .028). Cyclosporine prophylaxis withdrawal in critically ill allo-HSCT patients in the ICU appears to be feasible and did not impair long-term outcome.

Venetoclax (VEN) belongs the BH3-mimetic class that selectively targets BCL-2, activating apoptosis. The combination of VEN and azacitidine (AZA) has changed the paradigm of treatment of newly diagnosed (ND) acute myeloid leukemia (AML) patients ineligible for intensive chemotherapy. There is scarce evidence for the use of VEN-AZA for relapsed or refractory (R/R) AML. We compared the outcome of 39 R/R AML and 38 ND AML patients treated between 01/20 and 12/21. The median age was 69 (22-86) and 73 (61-81) in the R/R and ND groups, respectively. Adverse cytogenetics were found in 36% of patients in the R/R group and 59% of patients in the ND group. Overall response rate was 37% in R/R AML, including 13% CR, 8% CRi, 3% PR and 13% MLFS, and 58% in the ND AML, including 32% CR, 13% CRi and 13% MLFS. Adverse cytogenetics was associated with treatment failure in the R/R group (Relative Risk = 0.13, p = 0.005). Median overall survival (OS) was 5.9 months in the R/R group and 9.4 months in the ND group. Median OS was 2.2 months in the adverse cytogenetics group versus 8.7 months in the intermediate cytogenetics group in the R/R group (p = 0.02). Median leukemia-free survival was not different between the two groups (9.4 months and 10.3 months), indicating that VEN-AZA can be an efficient salvage treatment for selected R/R AML patients. In conclusion, VEN-AZA is a promising treatment for ND AML and for selected R/R AML patients.

Venetoclax is a BH3-mimetics agent specifically interacting with the antiapoptotic protein BCL-2, facilitating cytochrome c release from mitochondria, subsequent caspases activation, and cell death. Utilization of venetoclax has profoundly changed the landscape of treatment for the poor-prognosis category of AML patients unfit for intensive chemotherapy. In the phase III VIALE-A study, Venetoclax, in combination with the hypomethylating agent azacitidine, showed a 65% overall response rate and 14.7-month overall survival, in comparison with 22% and 8 months in the control arm. These results led to the widespread use of venetoclax in this indication. Other combination regimens, consisting of low-intensity, intensive, or targeted therapies are currently under evaluation. Despite promising results, preventing relapses or resistance to venetoclax is still an unmet clinical need. Numerous studies have been conducted to identify and overcome venetoclax resistance in preclinical models or in clinical trials, including the inhibition of other antiapoptotic proteins, the induction of proapoptotic BH3-only proteins, and/or the targeting of the mitochondrial metabolism and machinery.
