Efficacy of Dose-Adjusted Regimen on Survival in Frail Adults With Acute Lymphoblastic Leukemia

Summary

Acute lymphoblastic leukemia (ALL) is characterized by the abnormal proliferation of immature precursor cells, disrupting normal hematopoiesis and causing severe anemia and thrombocytopenia due to genetic mutations. Conventional treatment with intensive chemotherapy is limited for elderly patients or those with comorbidities, adversely affecting their survival. In Mexico, alongside a higher incidence, treatment-related complications are more frequent, particularly with drugs such as asparaginase or anthracyclines, which limits therapeutic efficacy. The transition to infusion-based therapies promises to reduce these complications, improve treatment tolerance, and optimize clinical outcomes, marking a significant advancement in the management of this disease. Modifying treatment regimens toward infusion therapies has the potential to significantly reduce adverse complications, enhance treatment tolerance, and ultimately improve clinical outcomes for patients who cannot benefit from conventional intensive regimens. This approach not only aims to optimize treatment effectiveness but also to minimize associated risks, thus representing an important advancement in the management of acute lymphoblastic leukemia in clinical settings such as those in Mexico
