Among the purine analogs, 2-chlorodeoxyadenosine (2-CDA) is particularly effective for the treatment of hairy cell leukemia and Waldemstrom's macroglobulinemia. Both efficacy and toxicity of 2-CDA were evaluated in previously treated patients affected with chronic lymphoproliferative disorders such as low-grade non-Hodgkin's lymphoma (NHL) and B-cell chronic lymphocytic leukemia (CLL). Thirty cases, mainly refractory, 16 affected with CLL, were included from six centers of the International Society for Chemo-Immunotherapy (IGCI). 2-CDA was administered in a 2 h i.v. infusion for 5-7 days at the standard dose of 0.1 mg/kg/day every 4 weeks. The median number of cycles was 3. Of 30 cases, eight (26.7%) achieved a complete remission (CR), nine (30%) a partial remission (PR), and two (6.7%) a minor response, while five cases (16.6%) did not respond, and six (20%) were considered early deaths. The overall response rate (CR + PR) was 56.7%, with a median response duration of 12 months (range 3-28 +) and a better response in CLL patients. Considering that the majority of patients were heavily pretreated, toxicity was acceptable, with 40% of cases not presenting any toxic effect. The main toxicity consisted in infectious complications. Based on the results of the present study, we confirm that 2-CDA is an effective drug in these lymphoproliferative disorders, suggesting its possible use either alone or in combination, also as first-line therapy.
