Safety and tolerability of intrathecal liposomal cytarabine as central nervous system prophylaxis in patients with acute lymphoblastic leukemia. Issue 8 (August 2014) - Valentin, Angelika
Abstract Central nervous system recurrence in acute lymphoblastic leukemia (ALL) occurs in up to 15% of patients and is frequently associated with poor outcome. The purpose of our study was to evaluate the efficacy and safety of a slow-release liposomal formulation of cytarabine for intrathecal (IT) meningeal prophylaxis in patients suffering from ALL. Forty patients aged 20–77 years (median 36) were preventively treated with a total of 96 (range 1–6) single doses containing 50 mg of liposomal cytarabine on a compassionate use basis. After a median observation period of 23 months (range 2–118) only two patients experienced a combined medullary–leptomeningeal disease recurrence after primary diagnosis. Except for headache grade 2 in two patients, no specific toxicity attributable to IT liposomal cytarabine application was noted. Long-term neurological side effects were not observed. IT liposomal cytarabine therapy with concomitant dexamethasone appears to be feasible and well tolerated.
