title: Colchicine in refractory chronic lymphocytic leukemia. A Southwest Oncology Group study.
abstract: Fourteen patients with active chronic lymphocytic leukemia who had failed prior therapy were treated with progressive doses of weekly intravenous colchicine beginning at 2 mg and escalating as high as 7 mg in a single injection. Responses were seen in two of 14, with a lessening of adenopathy and splenomegaly. Toxicity was characterized by gastrointestinal intolerance in eight and thrombocytopenia in 12. There is activity of the drug in chronic lymphocytic leukemia but, as administered in this study, high dose therapy is not ideal and it may be more beneficial if the drug were given as low dose daily or weekly therapy.
