benefit those with hematologic resistance or those who never had a cytogenetic response with standard-dose imatinib. Dose escalation of imatinib might be beneficial for patients with suboptimal response to imatinib, 400 mg daily (see Suboptimal Response

Biol Chem 2000 ; 275 : 18581 – 18585 . 27 Alvarado Y Kantarjian H O’Brien S . Significance of suboptimal response to imatinib, as defined by the European LeukemiaNet, in the long-term outcome of patients with early chronic myeloid leukemia

modifications were defined as a dose increase or decrease compared with the starting dose. Reasons for dose modifications were characterized in relation to an ADE, suboptimal response, or treatment failure. Imatinib discontinuation was defined as a change to an

recommendations, however ( Table 2 ). 2 - 4 The ELN defines failure and suboptimal response and includes an additional response category (warnings), whereas the NCCN Guidelines do not formally define suboptimal response, but rather define target responses at

organic cation transporter-1 (hOCT1) have been reported as being the most powerful predictor of response to imatinib. 91 White et al. 92 recently reported that most patients with suboptimal response to imatinib have low hOCT1 activity. In the updated

survival rates of 80% to 100% with complete resection. However, tumors located along the midline and disseminated PAs have a suboptimal response to conventional chemotherapy and a relatively poor prognosis. 7 There are several reports of successful
