Acute lymphoblastic leukaemia (ALL) is a diverse hematologic cancer that is characterised by unchecked lymphoid progenitor cell growth. Recent advancements in molecular profiling techniques have led to the identification of distinct molecular subtypes within ALL, providing valuable insights into the disease's pathogenesis and clinical behavior. This review aims to summarize the current understanding of molecular subtypes in ALL and highlight emerging therapeutic strategies tailored to specific subgroups. The emergence of personalised therapy strategies has revolutionised our understanding of ALL and its molecular subtyping. Emerging medicines have the potential to improve outcomes and lessen side effects by focusing on particular genetic defects and biochemical pathways linked to various subtypes. For the benefit of patients with ALL, more studies and clinical trials are necessary to improve and validate these novel therapy approaches.

Significant advancements in molecular profiling techniques have provided valuable insights into the genetic landscape of ALL, leading to the identification of distinct molecular subtypes within the disease. This enhanced understanding of the molecular subtypes has paved the way for the development of targeted therapies tailored to specific subgroups of patients, heralding a new era in the management of ALL .
Historically, the immunophenotypes and physical aspects of ALL were used to classify the disease. High-throughput genomic technologies have, however, completely changed our understanding of the illness by making it possible to profile all genetic aberrations, including chromosomal rearrangements, gene mutations, and anomalies in gene expression. All of the molecular subtypes of ALL, including B-cell precursor ALL (BCP-ALL), T-cell ALL (T-ALL), and Philadelphia chromosome-positive ALL (Ph+ ALL), each with distinctive genetic characteristics and clinical characteristics, have been related to these molecular abnormalities .
T-cell progenitors undergo a malignant change, which distinguishes T-ALL from other types of ALL. Recent investigations have found promising treatment targets, despite the fact that T-ALL has demonstrated a lower frequency of targetable genetic changes compared to BCP-ALL. Emerging treatments are now being examined in preclinical and clinical investigations with the potential to improve treatment outcomes for T-ALL patients .
The BCR-ABL1 fusion gene results in the Philadelphia chromosome, which is a hallmark of Ph+ ALL. Tyrosine kinase inhibitors (TKIs) have completely changed how this subtype is managed. Historically, it was linked to poor outcomes. TKIs that target the aberrant BCR-ABL1 protein, like imatinib, dasatinib, and nicotine, enhance survival rates and lower relapse rates in patients with Ph+ ALL. For patients with this high-risk subgroup, these second-generation TKIs have shown improved efficacy and decreased rates of resistance, providing fresh hope .
The discovery of molecular subtypes in ALL has revolutionized our understanding of the condition and created opportunities for individualised therapy strategies. The promise for improved treatment outcomes, less treatment-related toxicities, and increased patient survival exists with targeted medicines designed to target certain molecular abnormalities and subtypes. Validating and improving these novel medicines is crucial to ensuring their successful integration into clinical practise for ALL patients. This requires ongoing research, clinical trials, and collaboration .
The identification of molecular subtypes in acute lymphoblastic leukemia (ALL) has revolutionized our understanding of the disease and has provided a framework for personalized therapeutic approaches. Overall, a new era in the treatment of ALL has begun because to molecular subtyping and cutting-edge therapeutics. Targeting particular genetic mutations and biological processes linked to various subtypes has made way for individualised therapy strategies. However, in order to validate and improve these novel medicines and ensure their effective integration into clinical practise, more research, clinical trials, and collaboration are required. For patients with ALL, continued research in this area has the potential to significantly improve outcomes and ultimately increase long-term survival rates.
