title: Initial alkylating agent chemotherapy in a leukemic hairy cell patient.
abstract: A patient with moderate splenomegaly and the leukemic phase of hairy cell leukemia presented with a white blood cell count (WBC) of 85,600/mm3 with 87% hairy cells and platelets of 125,000/mm3. Initial therapy consisted of chlorambucil alone at 4 mg each day. Within 6 months, the WBC decreased to 27,000/mm3 with 82% hairy cells, and the spleen was not palpable; platelets remained at 142,000/mm3. The patient has continued to do well for 2 years since the start of therapy, requiring no transfusions and having no problems secondary to organ infiltration. Selected hairy cell patients, those with a significant leukemic phase and with only mild thrombocytopenia, may benefit from initial chlorambucil therapy rather than immediate splenectomy.
