2-Chlorodeoxyadenosine activity in patients with untreated chronic lymphocytic leukemia.

Abstract

2-CdA has major activity in patients with previously untreated CLL, and the lower response rates seen in previously treated patients may be due in part to poor marrow reserve from prior therapy. Determination of the relative effectiveness of 2-CdA, fludarabine, and chlorambucil in the treatment of CLL patients will require a randomized trial.
