BACKGROUND: Fludarabine successfully treats chronic lymphocytic leukemia (CLL); however, its use may lead to significant myelosuppression and other toxicities. This article weighs the benefits against potential harms, highlighting strategies for appropriate patient selection and administration.
METHODS: Relevant studies were identified upon literature review, which were combined with our clinical and institutional experience.
RESULTS: Fludarabine-based regimens result in an overall response rate of approximately 95% and of untreated CLL patients. Fludarabine also causes potentially irreversible grade 3 or 4 cytopenias and infection in the majority of patients. Furthermore, future hematopoietic cell mobilization may be difficult and secondary myelodysplastic syndrome and leukemia occur in at least 3% of patients.
CONCLUSION: Fludarabine should be used judiciously in older patients, and avoided entirely in patients with renal insufficiency. Close monitoring of blood cell counts with appropriate dose reduction/omission is vital. Finally, alternatives such as pentostatin and bendamustine should be considered.
