Abstract

Whereas the prognosis of adult patients with Philadelphia-negative acute lymphoblastic leukemia (ALL) has greatly improved since the advent of pediatric-inspired regimens, the impact of initial central nervous system (CNS) involvement has not been formerly re-evaluated. We report here the outcome of patients with initial CNS involvement included in the pediatric-inspired prospective randomized GRAALL-2005 study. Between 2006 and 2014, 784 adult patients (aged 18-59 years) with newly diagnosed Philadelphia-negative ALL were included, of whom 55 (7%) had CNS involvement. In CNSpositive patients, overall survival was shorter (median 1.9 years vs. not reached, HR=1.8 [1.3-2.6], P

Abstract

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

Abstract

Synchronous diagnosis of acute myeloid leukemia (AML) and symptomatic multiple myeloma (MM) is a rare situation that poses serious therapeutic difficulties. We report the case of a 68-year-old male which evolved simultaneously to symptomatic MM and AML. Both diseases first responded to treatment for 40 months after 7+3 induction and maintenance therapy of azacytidine + lenalidomide. MM relapsed first and was treated with azacytidine + daratumumab, which led an additional 15 months of progression-free survival. Little myeloid clonal size reduction over time was seen. This case shows that AML and MM can be effectively treated simultaneously using appropriate combinations.

Abstract

Resistant acute myeloid leukemia (AML) exhibits mitochondrial energy metabolism changes compared to newly diagnosed AML. This phenotype is often observed by evaluating the mitochondrial oxygen consumption of blasts, but most of the oximetry protocols were established from leukemia cell lines without validation on primary leukemia cells. Moreover, the cultures and storage conditions of blasts freshly extracted from patient blood or bone marrow cause stress, which must be evaluated before determining oxidative phosphorylation (OXPHOS). Herein, we evaluated different conditions to measure the oxygen consumption of blasts using extracellular flow analyzers. We first determined the minimum number of blasts required to measure OXPHOS. Next, we compared the OXPHOS of blasts cultured for 3 h and 18 h after collection and found that to maintain metabolic organization for 18 h, cytokine supplementation is necessary. Cytokines are also needed when measuring OXPHOS in cryopreserved, thawed and recultured blasts. Next, the concentrations of respiratory chain inhibitors and uncoupler FCCP were established. We found that the FCCP concentration required to reach the maximal respiration of blasts varied depending on the patient sample analyzed. These protocols provided can be used in future clinical studies to evaluate OXPHOS as a biomarker and assess the efficacy of treatments targeting mitochondria.

Abstract

International audience; Whether the LSC17 gene expression can improve risk stratification in the context of NGS-based risk stratification and measurable residual disease (MRD) in AML patients treated intensively has not been explored. We analyzed LSC17 in 504 adult patients prospectively treated in the ALFA-0702 trial. Multiple (cyto)genetic alterations were associated with changes in LSC17, such as higher LSC17 in patients with RUNX1 or TP53 mutations, and lower scores in those with CEBPA and NPM1 mutations. LSC17-high patients had a lower rate of complete response (CR) or CR with incomplete platelet recovery (CRp) after one induction course in a multivariable analysis (OR=0.41, p=0.0007) accounting for European LeukemiaNet 2022 (ELN22) risk groups, age, and white blood cell (WBC) count. The LSC17-high status was associated with shorter overall survival (OS) (3-year OS: 70.0% versus 52.7% in LSC17-low patients, p

Abstract

Purpose: To provide insights into the diagnosis and management of therapy-related myeloid neoplasms (t-MN) following PARP inhibitors (PARPi). Experimental Design: In a French cancer center, we identified and described the profiles of 13 t-MN diagnosed among 37 patients with ovarian cancer referred to hematology consultation for cytopenia under PARPi. Next, we described these 13 t-MN post-PARPi among 37 t-MN post ovarian cancer according to PARPi exposure. Finally, we described 69 t-MN post-PARPi in a national cohort. Results: From 2016 to 2021, cumulative incidence of t-MN was 3.5% (13/373) among patients with ovarian cancer treated with PARPi. At time of hematologic consultation, patients with t-MN had a longer PARPi exposure (9 vs. 3 months, P = 0.01), lower platelet count (74 vs. 173 G/L, P = 0.0005), and more cytopenias (2 vs. 1, P = 0.0005). Compared with t-MN not exposed to PARPi, patients with t-MN-PARPi had more BRCA1/2 germline mutation (61.5% vs. 0%, P = 0.03) but similar overall survival (OS). In the national cohort, most t-MN post-PARPi had a complex karyotype (61%) associated with a high rate of TP53 mutation (71%). Median OS was 9.6 months (interquartile range, 4–14.6). In multivariate analysis, a longer time between end of PARPi and t-MN (HR, 1.046; P = 0.02), olaparib compared with other PARPi (HR, 5.82; P = 0.003) and acute myeloid leukemia (HR, 2.485; P = 0.01) were associated with shorter OS. Conclusions: In a large series, we described a high incidence of t-MN post-PARPi associated with unfavorable cytogenetic and molecular abnormalities leading to poor OS. Early detection is crucial, particularly in cases of delayed cytopenia.

Abstract

Subsequent blast (BP) or accelerated phase (AP) is a severe complication of Philadelphia-negative myeloproliferative neoplasms (MPNs). The prognosis is generally dismal, but hypomethylating agents (HMAs) may induce a long-lasting response in a minority of patients. Here, we report a cohort of six patients with BP/AP-MPN who experienced MPN relapse after a leukemia response was obtained with azacytidine. Five of the patients achieved complete remission despite the presence of characteristics associated with poor prognosis, such as complex and monosomal karyotypes, TP53 mutations, and EVI1 overexpression. These remissions persisted for over five years in four of the 6 patients. All patients showed rapid reemergence of MPN within a median of two months with thrombocytosis requiring the addition of anagrelide, hydroxyurea, or ruxolitinib given continuously in parallel with the azacytidine cycle. Serial JAK2 V617F allelic burden measurements showed little variation. Thromboembolic events occurred in 3 patients, one leading to death. These findings confirm that HMA may reverse the disease course in AP/BP-MPN to a more chronic phase that may last for years but also lead to morbidity and mortality. Combining maintenance therapy with HMA and MPN-specific drugs appears to be a possible approach to avoiding leukemia relapse and controlling MPN disease.
