Olverembatinib combined with venetoclax and reduced-intensity chemotherapy for adult newly diagnosed Philadelphia chromosome-positive acute lymphoblastic leukemia: a single-center, single-arm, phase 2 trial.

Tyrosine kinase inhibitors (TKIs) combined with chemotherapy and immunotherapy evolved as the standard treatment for newly diagnosed (ND) Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph ALL). Nonetheless, the efficacy and safety of combining TKIs with BCL-2 inhibitors in ND Ph ALL have yet to be fully elucidated. Hence, we carried out a prospective clinical trial to explore the efficacy and safety of olverembatinib combined with venetoclax and reduced-intensity chemotherapy as frontline treatment in Ph ALL.

Comprehensive omics-based classification system in adult patients with B-cell acute lymphoblastic leukemia.

B-cell acute lymphoblastic leukemia (B-ALL) is a highly heterogeneous disease with a challenging prognosis, particularly in adult patients. We enrolled 88 adult B-ALL patients with transcriptomic and mutation profiles for classification system identification, and a comprehensive system for B-ALL patients (COMBAT) was developed. COMBAT stratified patients into three cohorts: (1) COMBAT1, characterized by high stem/myeloid antigen expression, low immune infiltration, high infiltration of endothelial cells, and hypo-CIMP (CpG island methylator phenotype); (2) COMBAT2, defined as an inflamed subtype with immune exhaustion, moderate myeloid antigen expression, and hypo-CIMP; and (3) COMBAT3, marked by proliferative profiles with MYC pathway activation and hypomethylation at enhancer regions in patients characterized by CIMP.

Risk stratification in the clinical application of minimal residual disease assessment in acute myeloid leukemia.

Background: In acute myeloid leukemia (AML), further investigation is warranted to integrate measurable residual disease (MRD) with genetic characteristics for formulating a dynamic prognostic system for predicting response and selecting appropriate postremission therapeutic strategies.

Methods: The authors incorporated MRD with genetic risk classification and assessed its impact on transplantation decision making within different risk cohorts, comprising 769 patients with newly diagnosed AML across three clinical trials. Only patients who achieved complete remission (CR) within two courses of chemotherapy were selected.

Treatment Patterns and Mutation Testing Among Patients with Acute Myeloid Leukemia in China: A Retrospective Observational Study.

Introduction: For acute myeloid leukemia (AML), prognosis is particularly poor in patients harboring FMS-like tyrosine kinase 3 () gene mutations, though routine screening for these mutations at diagnosis has been shown to be insufficient. The understanding of the impact of mutations on treatment decisions is limited.

Methods: In this retrospective, observational study, we investigated the key epidemiological characteristics, treatment patterns and responses among adult patients with newly diagnosed (ND) AML in China, who initiated treatment from January 1, 2015, to December 31, 2019, or progressed to relapsed/refractory (R/R) AML by December 31, 2020.

A pediatric-inspired regimen for adolescent and adult patients with Philadelphia chromosome-negative acute lymphoblastic leukemia: a prospective study from China.

Several international centers have used and reported on pediatric-inspired regimens to treat adolescent and adult patients with Philadelphia chromosome-negative acute lymphoblastic leukemia (Ph- ALL). However, there is a lack of prospective data from the Chinese population. We performed a prospective study with a pediatric-inspired regimen (IH-2014 regimen) to treat adolescent and adult Ph- ALL patients in our center.

RBFOX2 confers tumor growth by PI3K/AKT and MAPK signaling in gastric cancer.

RNA-binding Fox (RBFOX)2, a member of a family of RNA-binding proteins, is well known as a regulator of alternative pre-mRNA splicing. However, its possible role in gastric cancer is unknown. In this study, we investigated the biologic role and clinical significance of RBFOX2 in gastric cancer growth and elucidated its underlying molecular mechanisms.

Polymorphisms in 183 Chinese patients with ALL were analyzed using TaqMan single nucleotide polymorphism genotyping assay.

Prognostic significance of copy number variation in B-cell acute lymphoblastic leukemia.

Copy number variations (CNVs) are widespread in both pediatric and adult cases of B-cell acute lymphoblastic leukemia (B-ALL); however, their clinical significance remains unclear. This review primarily discusses the most prevalent CNVs in B-ALL to elucidate their clinical value and further personalized management of this population. The discovery of the molecular mechanism of gene deletion and the development of targeted drugs will further enhance the clinical prognosis of B-ALL.

A short report of novel gene in resembling acute promyelocytic leukemia.

Background: Resembling acute promyelocytic leukemia (APL) is a unique subtype of APL who sharing clinical, morphological, and immunophenotypic features with typical APL, but lacking evidence of fusion gene and usually insensitive to arsenic trioxide (ATO) and all-trans retinoic acid (ATRA). For years, rearrangement were found in resembling APL continually. The confirmed partner genes of rearrangement included , , , , and .

The clinical characteristics and prognosis in adult Ph negative acute lymphoblastic leukemia with TP53 aberrations.

Very few reports elucidate the prognosis of patients with TP53 aberrations using both measurable residual disease (MRD) and the status of having undergone allogeneic hematopoietic stem cell transplantation (allo-SCT). In this study, aberrations of TP53 were analyzed using next-generation sequencing (NGS) and fluorescence in situ hybridization (FISH) in patients with Philadelphia chromosome-negative (Ph) ALL enrolled in a prospective single-arm clinical trial at our leukemia center. We analyzed the survival of the patients grouped according to the MRD level at the third month and whether or not received allo-SCT.

Comparison of multi-omics results between patients with acute myeloid leukemia with long-term survival and healthy controls.

Background: Acute myeloid leukemia (AML) is a group of highly heterogeneous diseases, for which approximately 35-40% of patients younger than 60 years old can be cured. However, the multi-omics characteristics and immune cell infiltration (ICI) status of adult long-term survival patients with AML patients compared with healthy controls are still relatively under-explored.

Methods: A total of 10 healthy transplant donors (control group) and 11 long-term survival patients with AML with sampling from 2019 to 2020 at the Institute of Hematology in the Hospital of Blood Diseases were enrolled.

The prognostic factors in acute myeloid leukaemia with double-mutated CCAAT/enhancer-binding protein alpha (CEBPAdm).

The prognostic factors to stratify acute myeloid leukaemia (AML) with double-mutated CCAAT/enhancer-binding protein alpha (CEBPAdm) into different risk groups remains to be determined. In this retrospective study, we evaluated 171 consecutive patients with newly diagnosed AML with CEBPAdm by a Cox proportional hazards regression model. In univariate analyses, colony stimulating factor 3 receptor (CSF3R) and Wilms tumour 1 (WT1) mutations were associated with poor relapse-free survival (RFS).

Gene Deletions and Prognostic Values in B-Linage Acute Lymphoblastic Leukemia.

Although pediatric-like treatment regimen has remarkably improved the survival rates of adults with acute lymphoblastic leukemia (ALL), the outcome of some adult patients is still poor owing to adverse genetic features.
