ABSTRACT
Introduction: First and second generation tyrosine kinase inhibitors, represent a new, fully biologic and targeted approach to chronic lymphocytic leukemia and allowed to obtain high responses and acceptable tolerability even in elderly and high risk patients. On the other hand, prolonged experience with these agents has raised some questions on unexpected toxicities, response quality, treatment duration and onset of resistances.
Areas covered: This review analyzes the main published studies with the aim to discuss whether, in future, new agents could become a part of standard treatments or even replace the chemo-immunotherapy in chronic lymphocytic leukemia.
Expert commentary: Despite different trials has been already published and many are still ongoing, follow up times are, at present, too short.
A chemo-free approach surely represents a desirable goal for chronic lymphocytic leukemia, nevertheless longer observation is warranted to better define the correct use of targeted therapies.
