BCR-ABL Messenger RNA Levels Continue to Decline in Patients with Chronic Phase Chronic Myeloid Leukemia Treated with Imatinib for More Than 5 Years and Approximately Half of All First-Line Treated Patients Have Stable Undetectable BCR-ABL Using Strict Sensitivity Criteria

Abstract Purpose: In the first years of imatinib treatment, BCR-ABL remained detectable in all but a small minority of patients with chronic myeloid leukemia. We determined whether BCR-ABL continues to decline with longer imatinib exposure and the incidence and consequence of undetectable BCR-ABL. E... View More
