Overview

B-lymphoblastic leukemia/lymphoma (B-ALL/LBL) with recurrent genetic abnormalities is an aggressive hematologic malignancy characterized by specific cytogenetic and molecular alterations that dictate prognosis and therapeutic approaches. These include high-risk variants like BCR::ABL1 (Philadelphia chromosome) and KMT2A rearrangements, as well as favorable-risk abnormalities such as ETV6::RUNX1 fusion. Diagnosis requires immunophenotyping and genetic profiling to guide risk stratification [1][2][5].

Population

  • Bimodal age distribution: peak in children <6 years (75% of cases) and adults >65 years [1][6]

  • Accounts for 25% of adult ALL cases and 20-30% of pediatric relapsed/refractory ALL [5][9]

  • Higher incidence in Hispanics and Native Americans with CRLF2 abnormalities [5][10]

Burden

  • 5-year survival: >90% in children vs 40% in adults [10][14]

  • Accounts for 1.2% of lymphoid neoplasms with 1.6 cases/100,000 annually [1][14]

  • Adult mortality exceeds 80% in relapsed cases despite novel therapies [7][15]

Therapies

  • Targeted therapies: Tyrosine kinase inhibitors (e.g., imatinib) for BCR::ABL1+ cases; menin inhibitors for KMT2A-rearranged disease [3][7][15]

  • Immunotherapy: CD19-directed CAR T-cells (tisagenlecleucel) and blinatumomab for relapsed/refractory cases [7][11]

  • Transplant: Allogeneic HSCT recommended for high-risk genetic profiles (e.g., hypodiploidy, KMT2A rearrangements) [4][16]

Categories: rare genetic diseases, rare hematological diseases, rare neoplastic diseases, rare transplant-related disorders

2024-03-21 | Different Levels of Therapeutic Strategies to Recover the Microbiome to Prevent/Delay Acute Lymphoblastic Leukemia (ALL) or Arrest Its Progression in Children

Alterations in the composition and diversity, metabolism, and products of the microbiome, and of the gut microbiome (GM), have been shown to be closely associated with the onset and progression of many human diseases, including cancer (i.e. hematological neoplasms). Acute lymphoblastic leukemia (ALL) is the most common form of childhood malignancy. Affected cases present typical alterations of GM, followed by inflammation, which contribute to its progression, response to therapy, as well as possible relapses. Recent evidence also reports that GM influences the development and functions of the newborn&#039;s hematopoietic system through the process of developmental programming during fetal life, as well as its susceptibility to the onset of onco-hematological pathologies, namely ALL. Furthermore, in children with ALL, GM has been found to vary in composition, variety, and functions during the clinical stages of ALL, and such variation may influence and predict the complications and prognosis of ALL after chemotherapy treatment or stem cell hematopoietic transplant. Here, we suggest some therapeutic strategies, which can be applied at two levels of intervention to recover the microbiome, and consequently prevent/delay ALL or arrest its progression.

2024-02-21 | Biological Markers of High-Risk Childhood Acute Lymphoblastic Leukemia

Childhood acute lymphoblastic leukemia (ALL) has witnessed substantial improvements in prognosis; however, a subset of patients classified as high-risk continues to face higher rates of relapse and increased mortality. While the National Cancer Institute (NCI) criteria have traditionally guided risk stratification based on initial clinical information, recent advances highlight the pivotal role of biological markers in shaping the prognosis of childhood ALL. This review delves into the emerging understanding of high-risk childhood ALL, focusing on molecular, cytogenetic, and immunophenotypic markers. These markers not only contribute to unraveling the underlying mechanisms of the disease, but also shed light on specific clinical patterns that dictate prognosis. The paradigm shift in treatment strategies, exemplified by the success of tyrosine kinase inhibitors in Philadelphia chromosome-positive leukemia, underscores the importance of recognizing and targeting precise risk factors. Through a comprehensive exploration of high-risk childhood ALL characteristics, this review aims to enhance our comprehension of the disease, offering insights into its molecular landscape and clinical intricacies in the hope of contributing to future targeted and tailored therapies.

2024-01-07 | CAD204520 Targets NOTCH1 PEST Domain Mutations in Lymphoproliferative Disorders

NOTCH1 PEST domain mutations are often seen in hematopoietic malignancies, including T-cell acute lymphoblastic leukemia (T-ALL), chronic lymphocytic leukemia (CLL), splenic marginal zone lymphoma (SMZL), mantle cell lymphoma (MCL), and diffuse large B-cell lymphoma (DLBCL). These mutations play a key role in the development and progression of lymphoproliferative tumors by increasing the Notch signaling and, consequently, promoting cell proliferation, survival, migration, and suppressing apoptosis. There is currently no specific treatment available for cancers caused by NOTCH1 PEST domain mutations. However, several NOTCH1 inhibitors are in development. Among these, inhibition of the Sarco-endoplasmic Ca2+-ATPase (SERCA) showed a greater effect in NOTCH1-mutated tumors compared to the wild-type ones. One example is CAD204520, a benzimidazole derivative active in T-ALL cells harboring NOTCH1 mutations. In this study, we preclinically assessed the effect of CAD204520 in CLL and MCL models and showed that NOTCH1 PEST domain mutations sensitize cells to the anti-leukemic activity mediated by CAD204520. Additionally, we tested the potential of CAD204520 in combination with the current first-line treatment of CLL, venetoclax, and ibrutinib. CAD204520 enhanced the synergistic effect of this treatment regimen only in samples harboring the NOTCH1 PEST domain mutations, thus supporting a role for Notch inhibition in these tumors. In summary, our work provides strong support for the development of CAD204520 as a novel therapeutic approach also in chronic lymphoproliferative disorders carrying NOTCH1 PEST domain mutations, emerging as a promising molecule for combination treatment in this aggressive subset of patients.

2023-12-27 | Mutational and transcriptional landscape of pediatric B-cell precursor lymphoblastic lymphoma

Abstract Pediatric B-cell precursor (BCP) lymphoblastic malignancies are neoplasms with manifestation either in bone marrow/blood (BCP acute lymphoblastic leukemia, BCP-ALL) or less common in extramedullary tissue (BCP lymphoblastic lymphoma, BCP-LBL). Although both presentations are similar in morphology and immunophenotype molecular studies are virtually restricted to BCP-ALL so far. The lack of molecular studies on BCP-LBL is probably due to its rarity and the restriction to tiny, mostly formalin-fixed paraffin embedded (FFPE) tissues. Here we present the first comprehensive mutational and transcriptional analysis of what we consider the largest BCP-LBL cohort described to date (n=97). Whole exome sequencing indicates a mutational spectrum of BCP-LBL strikingly similar to that found in BCP-ALL. However, epigenetic modifiers were more frequently mutated in BCP-LBL, whereas BCP-ALL was more frequently affected by mutation in genes involved in B-cell development. Integrating copy number alterations, somatic mutations and gene expression by RNA-sequencing revealed virtually all molecular subtypes originally defined in BCP-ALL to be present in BCP-LBL too, with only 7% of lymphomas that were not assigned to a subtype. Therefore, the results here described may pave the way for molecular risk adapted treatment protocols for BCP-LBL patients. Keypoints Comprehensive molecular characterization of B-cell precursor lymphoblastic lymphoma allows molecular subtyping analogous to leukemias Compared to leukemias, lymphomas show more alterations in epigenetic modifiers and less in B-cell development genes

2023-12-26 | Synthetic Lethality Approaches in Acute Lymphoblastic Leukemia

Acute lymphoblastic leukemia (ALL), a remarkable cancer that mainly affects children, has seen commendable advances in its treatment. However, the occurrence of relapses after initial treatments poses a major threat and is one of the leading causes of cancer-related mortality in pediatric patients. To address this problem, innovative therapeutic approaches for ALL need to be continuously developed and refined. Synthetic lethality, an interaction between genes in which alteration of only one allows survival, but simultaneous alteration of both leads to inviability, is emerging as a promising therapeutic approach against ALL and other cancers. In this regard, the review aims to examine the documented cases of synthetic lethality in ALL reported to date (2023) and to elucidate the molecular mechanisms underlying this phenomenon. Furthermore, this review explores possible targets that have so far gone unnoticed, justifying their importance in this context.
