How to Choose Frontline Therapy for Chronic Myelogenous Leukemia: So Many Drugs, Not So Many Patients: What To Do?

processing....

What To Do?

Compared with 10 years ago, hematologists treating patients with CML have the enviable problem of having to choose among 3 outstanding agents. Based on recent studies, it is clearly justified to start dasatinib or nilotinib in patients with newly diagnosed CP-CML, particularly those with high-risk disease. The recent report of the NCCN Task Force on the use of TKIs in the treatment of CML states that imatinib continues to be a reasonable choice for patients with low-risk Sokal or Hasford scores, but strongly recommends the use of dasatinib or nilotinib for those with intermediate- or high-risk scores.[35] However, one must individualize the decision for each patient based on comorbidities, drug interactions, and lifestyle. Nilotinib may not be a good choice for patients whose lifestyle prevents them from having to take an oral medication twice a day on an empty stomach. Nor may it be a good choice for patients with a history of pancreatitis. Likewise, dasatinib may not be a good choice for patients who need to take a proton pump inhibitor on a sustained basis. Nor may it be a good choice for patients who have a history of congestive heart failure or pleural effusions.

Pharmacoeconomic considerations are likely to become more significant in a few years when imatinib is expected to go off-patent. However, even though the hematologist’s task in treating CML has become more complicated, patients with CML now are in a much better position and have a much better outlook than just a few years ago.
