Abstract
The US Food and Drug Administration has approved TNF(Tumor necrosis factor) alpha inhibitors to manage a range of inflammatory conditions, including Crohn's disease, rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis and other inflammatory disorders. However, these inhibitors can potentially increase the risk of secondary blood malignancies due to TNF alpha's role in various cellular processes such as angiogenesis, cell cycle proliferation, apoptosis and differentiation. In this article, we present a unique case study of a patient who developed Philadelphia-positive acute lymphoblastic leukaemia (ALL) while receiving adalimumab, a potent monoclonal antibody that specifically binds to TNF-alpha. We describe the patient's successful treatment using standard-of-care chemotherapy and tyrosine kinase inhibitors, resulting in complete remission with no measurable residual disease. Furthermore, we conducted a literature review on this subject and identified five similar cases of ALL associated with TNF alpha inhibitors.
