    Abstract:
    Fludarabine (9-beta-D-arabinofuranosyl 2-fluoro-adenine monophosphate) is a fluorinated analogue of adenine which is relatively resistant to deamination by adenosine deaminase. Phase I clinical trials disclosed significant antitumor activity in lymphoid malignancies. Fludarabine has been used in the treatment of CLL since March, 1985, at a dose of 25-30 mg/m2/day x 5 days each 3-4 weeks by short intravenous infusion. Sixty-eight previously treated patients with CLL are evaluable for response. The median age was 60 years, 50 were male the median number of prior chemotherapy regimens was 2, and the median time from initial chemotherapy to fludarabine was 45 months. Forty-three (63%) were Rai stages 3 and 4, 31 (46%) were Binet Stage C. Twenty patients (29%) obtained a complete remission (CR), defined as peripheral lymphocytes less than 4,000/microliters, no clinical evidence of disease, less than 30% of lymphocytes in the bone marrow (with no residual nodules), or a nodular partial remission, NPR (CR except for residual lymphoid nodules), and 19 (28%) a partial remission (less than 50% reduction in tumor in nodes, liver, spleen and bone marrow and greater than 1 log reduction in the lymphocyte count). The complete remission rate for the various involved sites were blood (69%), liver (52%), spleen (55%), and nodes (48%). The bone marrow was the least responsive site with 16% CR and 44% PR. The number of prior regimens did not have a significant response rate or survival. The serum albumin , alkaline phosphatase, platelet and hemoglobin level all were associated with survival from the start of fludarabine.(ABSTRACT TRUNCATED AT 250 WORDS)
