RESUMO
In recent years, the outcome of Burkitt leukemia/lymphoma (BL) has improved significantly. Central nervous system (CNS) involvement continues to be a poor prognostic indicator. High doses of intravenous polychemotherapy, intrathecal chemotherapy, and cranio-spinal radiation therapy are used by numerous groups. Majority of patients are cured after this strategy. The next challenge is to decrease toxicities of treatment, including long-term toxicities secondary to cranio-spinal radiation therapy observed in these cured patients. Liposomal cytarabine could be a good alternative to cranio-spinal radiation therapy as already reported in acute lymphoblastic leukemia. We report here eleven patients treated in our center for BL, with liposomal cytarabine instead of cranio-spinal radiation therapy as prophylactic or curative treatment for CNS involvement. Treatment was safe with no short-term grade >3 adverse events. Moreover, no long-term side effects and no impact on outcome were observed. We conclude that LC could be a good option to decrease short/long-term side effects of cranio-spinal radiation therapy in BL and could be evaluated in a future clinical trial.
