Venetoclax (Ven) plus hypomethylating agents are considered standard-of-care for patients with acute myeloid leukemia (AML) judged ineligible for intensive chemotherapy (IC). Real-world studies complement clinical trials, since patterns of patient selection, treatment-exposure and post-remission management may vary. This prospective observational multi-center study included 209 newly diagnosed IC-ineligible patients with a median age 75 years (interquartile range, 71-81 years).

Resistance to chemotherapy remains a major hurdle to the cure of Acute Myeloid Leukemia (AML) patients. Recent studies indicate a minority of malignant cells, termed drug-tolerant persisters (DTPs), stochastically upregulate stress pathways to evade cell death upon acute exposure to chemotherapy without acquiring new genetic mutations. This chemoresistant state is transient and the cells return to baseline after removal of chemotherapy.

Article Synopsis
  • * Researchers studied immune cell variations in the bone marrow of 54 genetically diverse mouse strains, discovering that these variations are polygenic and linked to gene functions related to growth and balance of immune cells.
  • * They also identified an intriguing mechanism, called "cyto-trans," where genes affect immune cell types differently than expected, revealing that such genes have undergone less negative selection over time, enhancing the immune system's adaptability and evolution.

Patients with FLT3-mutated acute myeloid leukaemia (AML) that relapse or are refractory (R/R) to intensive induction have poor outcomes. Gilteritinib has recently become standard-of-care for patients with R/R FLT3-mutated AML. We investigated whether adding venetoclax to gilteritinib (gilt-ven) improves outcomes as compared with gilteritinib monotherapy.

Introduction: Mind-body intervention (MBI) serves as a supportive aid in oncology. We hypothesized that MBI could impact the progression of chronic lymphocytic leukemia (CLL) in the "watch and wait" (w&w) phase.

Methods: We conducted a non-randomized, prospective controlled study between the years 2020 and 2022 on 76 treatment-naïve CLL patients in the w&w phase.

  • The study evaluated the use of deferiprone (DFP), an oral iron-chelating drug, in patients with lower risk myelodysplastic syndromes (MDSs) who are dependent on red blood cell (RBC) transfusions and suffer from iron overload.
  • Eighteen adult patients treated with DFP for 4 months showed significant reductions in oxidative stress markers, including a 58.6% decrease in reactive oxygen species (ROS), and improvements in other parameters like reduced glutathione and lipid peroxidation.
  • No cases of agranulocytosis occurred during the study, indicating that DFP was tolerable, and the findings suggest potential benefits of D

Article Synopsis
  • The study investigated the effectiveness and optimal dosage of cusatuzumab, an anti-CD70 antibody, combined with azacitidine for treating acute myeloid leukaemia in patients not eligible for intensive chemotherapy.
  • Conducted across 40 hospitals in seven countries, the randomized trial assigned 103 adult patients to receive either 10 mg/kg or 20 mg/kg doses of cusatuzumab alongside azacitidine in 28-day cycles, aiming to evaluate complete remission rates.
  • Although 55% of patients experienced significant treatment results, the study was halted after part one due to changes in the treatment landscape that made continuing with further phases impractical.

During solid tumor progression, the tumor microenvironment (TME) evolves into a highly immunosuppressive milieu. Key players in the immunosuppressive environment are regulatory myeloid cells, including myeloid-derived suppressor cells (MDSCs) and tumor-associated macrophages (TAMs), which are recruited and activated via tumor-secreted cytokines such as colony-stimulating factor 1 (CSF-1). Therefore, the depletion of tumor-secreted cytokines is a leading anticancer strategy.

Objectives: Dysregulation of BCL-2 family members has been reported in acute lymphocytic leukemia (ALL), with various BH3-dependencies of the leukemic clone. We conducted a multicenter retrospective cohort of patients with relapsed/refractory B or T ALL, with ven-chemotherapy or ven-navitoclax combinations, to assess efficacy and safety.

Methods: Seventeen patients were included in the analysis, median age was 32 years, with 6 B-ALL and 11 T-ALL patients.

Since the early 1970s, the treatment of acute myeloid leukaemia (AML) has undergone a major transformation. Initially based on only two drugs, an anthracycline and cytosine arabinoside, the aim of therapy was to achieve a haematological response allowing patients to recover and go home. Back in those early days, cure was not a realistic expectation.

The European Union implemented data privacy laws in mid-2018 and the state of California enacted a similar law several weeks later. These regulations affect medical data collection and analysis. It is unclear if they achieve this goal in the realm of clinical trials.

While natural killer (NK) cells are essential players in detection and elimination of malignant cells, these surveillance properties can be compromised by cancer cells. Since NK cell education primarily occurs in the bone marrow and lymphoid tissue, this process might be particularly affected by their infiltration with lymphoma cells. This study aimed to explore functional properties of diffuse large B-cell lymphoma (DLBCL) patient NK cells, which could potentially promote tumour immune evasion and disease propagation.

Remission assessment in acute myeloid leukemia has evolved over the recent years with the advent of molecular and flow-based minimal residual disease determination. Nonetheless, early time point such as day 5 and day 14 (D14), still have prognostic and therapeutic implications. D14 refractory disease is regarded as a poor prognostic factor, however the therapeutic intervention is still under debate, with evidence suggesting a successful re-induction might offer similar long-term outcome as D14 aplasia.

Patients with FLT3-mutated relapsed or refractory (R/R) acute myeloid leukemia (AML) have a dismal prognosis. Gilteritinib is a FLT3 tyrosine kinase inhibitor (TKI) recently approved for patients with R/R AML. We aimed to characterize real-world data regarding gilteritinib treatment in FLT3-mutated R/R AML and to compare outcomes with matched FLT3-mutated R/R AML patients treated with chemotherapy-based salvage regimens.

Venetoclax in combination with intensive therapies is explored in both the upfront and relapse/refractory (R/R) setting, and available data suggest that such regimens are effective albeit with added hematological and infectious toxicity. We conducted a multicenter retrospective cohort study of patients with acute myeloid leukemia (AML) treated with venetoclax in combination with FLAG-IDA protocol. Twenty-five patients were included in this analysis (median age 53.

Article Synopsis
  • The Phase 3 trials Viale-A and Viale-C investigated the health-related quality of life (HRQoL) in patients with acute myeloid leukemia (AML) who were not suitable for intensive chemotherapy, focusing on treatments with venetoclax (VEN) combined with either azacitidine (AZA) or low-dose cytarabine (LDAC) versus placebo (PBO).
  • Key patient-reported outcomes measured included global health status, physical functioning, cancer fatigue, and overall health status, with results indicating that patients receiving VEN had significantly longer time to deterioration (TTD) in multiple HRQoL metrics compared to those on placebo treatments.
  • The findings suggest that ven
