ABSTRACT
<p><b>OBJECTIVE</b>To explore efficacy of imatinib for patients with chronic myeloid leukemia(CML) and its resistance-related factors during the treatment.</p><p><b>METHODS</b>The clinical data of 214 CML patients received imatinib were analyzed respectively in our hospital from April 2005 to December 2010. The therapy history and efficacy of regular follow-up and factors influencing drug resistance were analyzed. COX regression analysis was used to perform the univariate and multivariate analysis.</p><p><b>RESULTS</b>Until the end of follow up, thirty-one patients (14.5%) occurred drug resistance. One of them was in accelerated phase(AP), and two in blast phase(BP); 69.2% of patients achieved a complete cytogenetic response(CCyR), and 31.3% of patients achieved a major molecular response(MMR). COX analysis was performed in 207 chronic phase(CP) patients. Univariate analysis showed that the course of disease before treatment, the hemoglobin count, the white blood cell count, whether achieved CCyR or not and whether achieved MMR or not were the influencing factors for imatinib resistance. Multivariate analysis showed that whether achieved CCyR or not was the independent factor for drug resistance.</p><p><b>CONCLUSION</b>Whether achieved CCyR or not is an independent factor and also a protective factor for imatinib resistance in patients with CML.</p>
