Summary
Brief summary (as posted)
Imatinib mesylate is standard treatment of Chronic myeloid leukaemia, complete cytogenetic response is obtained in most of cases but molecular response concerned only a small part of the patients. To increase molecular response ratio we decided to increase imatinib dose to limited resistance to this drug and to add zoledronate for it anti tumoral activity to increase anti leukemic effect. We plan to accrue 37 patients in 5 centers. We will analyse molecular expression of BCR-ABL transcript after 6 months of treatment, safety, duration of response, VEGF expression and LTgd production.
