Activity of fludarabine in refractory chronic lymphocytic leukemia and low grade non-Hodgkin's lymphoma--the Jerusalem experience.
Twenty four patients with refractory chronic lymphocytic leukemia (CLL) and advanced low grade lymphoma (LGL) were treated with Fludarabine given at a dose of 25 mg/m2, intravenously daily for 5 days, every 28 days. Ten of the patients with LGL were in terminal leukemic phase. All patients had received previous chemotherapy, most with multiple regimens. Patients received a mean of 5.1 cycles (range 1-9). 4 patients--one with CLL and 3 with LGL--achieved a complete remission, while 7 LGL and 3 CLL patients had a partial response. Two patients remain in complete remission 23 and 25 months after completion of therapy. One patient underwent successful autologous bone marrow transplantation after achieving a complete remission, while two others had marrow cryopreserved during complete remission. The drug was well tolerated and toxicity was mild. In 9 of the 122 given cycles patients required hospitalization. In conclusion, Fludarabine is active in refractory patients with CLL and LGL and induces complete and partial remissions in some. It seems that Fludarabine could be used as primary therapy in these disorders in the future.
