Acute Myeloid Leukaemia and Acute Lymphoblastic Leukaemia Classification and Metabolic Characteristics for Informing and Advancing Treatment

Abstract

Acute myeloid leukaemia (AML) and acute lymphoblastic leukaemia (ALL) remain significant challenges in haematological oncology. This review examines the pathophysiology, classification, and risk stratification of these aggressive malignancies, emphasising their impact on treatment strategies and prognosis. We discuss current standard-of-care treatments, including chemotherapy regimens and targeted therapies, while addressing the associated adverse effects and hypersensitivity reactions. Delving into the metabolic characteristics and vulnerabilities of leukaemia cells, the review highlights the key differences between lymphoid and myeloid leukaemia and how metabolic insights can be utilised for therapeutic purposes, with special focus on asparaginase therapy and its potential for improvement in both ALL and AML treatment. The review conveys the importance of personalised medicine approaches based on individual metabolic profiles and the challenges posed by metabolic heterogeneity and plasticity in leukaemia cells. Combining molecular and metabolic profiling can enhance and refine treatment strategies for acute leukaemia, potentially improving patient outcomes and quality of life. However, integrating these into routine clinical practice requires overcoming various practical, technical, and logistical issues.
