The treatment of meningeal relapse in acute lymphoblastic leukemia (ALL) remains a challenging clinical problem. Liposomal cytarabine (DepoCyte) permits to decrease frequency of lumbar punctures, without loss of efficacy, because intrathecal levels of the drug remain cytotoxic for up to 14 days. We investigated the efficacy and safety of intrathecal DepoCyte in six children with meningeal relapse, treated in two pediatric institutions. DepoCyte was well tolerated in all patients, who achieved complete clearance of blasts from the cerebrospinal fluid after the first three intrathecal drug administrations. Five of the six patients were concurrently treated with high-dose administration of systemic cytarabine, without additional neurological side effects. Our results suggest that DepoCyte is a valid option for children with ALL experiencing meningeal relapse; it deserves further investigation in intensive treatment regimens, taking into due consideration potential neurotoxicity.

Abstract

The treatment of meningeal relapse in acute lymphoblastic leukemia (ALL) remains a challenging clinical problem. Liposomal cytarabine (DepoCyte) permits to decrease frequency of lumbar punctures, without loss of efficacy, because intrathecal levels of the drug remain cytotoxic for up to 14 days. We investigated the efficacy and safety of intrathecal DepoCyte in six children with meningeal relapse, treated in two pediatric institutions. DepoCyte was well tolerated in all patients, who achieved complete clearance of blasts from the cerebrospinal fluid after the first three intrathecal drug administrations. Five of the six patients were concurrently treated with high-dose administration of systemic cytarabine, without additional neurological side effects. Our results suggest that DepoCyte is a valid option for children with ALL experiencing meningeal relapse; it deserves further investigation in intensive treatment regimens, taking into due consideration potential neurotoxicity.
