Lifelong TKI therapy: how to manage cardiovascular and other risks
Michael J. Mauro
Abstract
Beginning with imatinib and now spanning 6 oral, highly active, and mostly safe agents, the development of specific targeted therapy for patients with chronic myeloid leukemia (CML) has created a new world featuring chronic maintenance chemotherapy for all treated as such, treatment-free remission, and functional cure after prolonged deep remission in a subset. As a result comes a necessary shift in focus from acute to chronic toxicity, increasing attention to patient comorbidities, and critical thinking around specific adverse events such as metabolic, cardiovascular, and cardiopulmonary effects, which vary from agent to agent. This review aims to pull together the state of the art of managing the "C" in CML-a chronic myeloproliferative neoplasm treated at present over many years with oral BCR-ABL-targeted agents in a population whose overall health can be complex and potentially affected by disease and therapy-and determine how we can better manage a highly treatable and increasingly curable cancer.
