Fludarabine phosphate is the 2-fluoro, 5'-monophosphate derivative of vidarabine (ara-A) with the advantages of resistance to deamination by adenosine deaminase (ADA) and improved solubility. The mechanism of cytotoxic action of the compound appears to involve metabolic conversion to the active triphosphate. Fludarabine phosphate has substantial activity against lymphoid malignancies, particularly chronic lymphocytic leukemia (CLL) and low-grade non-Hodgkin's lymphoma (NHL). Its single-agent activity in CLL appears at least comparable to those of other conventional combination regimens. Its activity in Hodgkin's disease, mycosis fungoides, and macroglobulinemia, although suggestive, needs to be further defined and clinical trials are warranted in hairy cell leukemia, prolymphocytic leukemia, and previously untreated myeloma. The compound does not appear active against most common solid tumors. Early clinical trials indicated significant myelosuppression and the potential for severe neurotoxicity. Toxicity on the currently used low-dose schedules includes transient and reversible myelosuppression, nausea and vomiting, diarrhea, somnolence/fatigue, and elevations of liver enzymes and/or serum creatinine. Possible pulmonary toxicity has been suggested in several patients. The currently used low-doses of fludarabine phosphate, even with repeated administration, are well tolerated and appear safe with a negligible risk for severe neurotoxicity. Based on its single-agent activity and tolerability, the Food and Drug Administration recently granted group C designation of the drug for the treatment of patients with refractory CLL outside the clinical trials setting. The use of fludarabine phosphate in combination regimens and its impact on the natural history of the lymphoid malignancies is yet to be determined. Fludarabine phosphate may well occupy a pivotal role in the management of CLL and low-grade NHL.

The review of Phase II trials in patients treated by Fludarabine phosphate (Fludara I.V) has been demonstrated to have unequivocal benefit for some patients with Chronic Lymphocytic Leukemia (CLL) non Hodgkin lymphoma and macroglobulinemia. Comparison of Fludara I.V with other treatment regimens is now studied in randomised protocols for B and C stages of CLL.

Up to two thirds of all patients affected by advanced Hodgkin's disease will be cured by chemotherapy alone or by combined chemoradiation modalities. High-dose chemotherapy with autologous stem cell rescue may be potentially curative for patients progressing under frontline chemotherapy or developing early relapse of disease. In spite of this, an unacceptably high percentage of these high-risk patients will relapse after salvage treatments and die of their disease. Fludarabine phosphate is an adenosine nucleoside analog highly active in chronic lymphocytic leukemia and low-grade non-Hodgkin's lymphomas. There are only few data in the literature concerning its use in the management of Hodgkin's disease. We report the case of an elderly, heavily pretreated Hodgkin's disease patient in progression under third-line chemotherapy who experienced good palliation of her B symptoms and a major clinical response of her refractory bone lesions with the administration of fludarabine as monotherapy. The treatment was well tolerated, without grade 4 hematological toxicity or opportunistic infections. The duration of clinical remission and systemic symptom palliation was 9 and 11 months, respectively. Further evaluation of fludarabine phosphate as salvage therapy in relapsed/refractory elderly Hodgkin's disease patients is needed.
