Experience of treatment of hairy cell leukemia with new drug Vero-cladribine

Between July 2005and October 2006, eight patients (pts) with hairy cell leukaemia were treated with Vero- cladribine at N.N. Blokhin Cancer Research Center. All pts achieved complete remission (CR). Duration of CR ranges from 1+ to 12+ months in 7 cases. There were no serious adverse events during the treatment and follow-up periods (1-12 months). Vero- cladribine was well tolerated. Anemia (grade IV) was seen in 1 patient and thrombocytopenia (grade I) was seen in another 1 patient. No one patient has febrile neutropenia or infectious complication.
