First immunochemotherapy outcomes in elderly patients with CLL: a retrospective analysis.

Background: To date, the majority of trials on chronic lymphocytic leukemia (CLL) focused on patients considerably younger than the median age of onset for CLL. As a result, no definitive treatment exists for elderly patients, especially less medically fit patients.

Objectives: The objectives of this study are to examine the impact of comorbidities on outcome as well as to compare three different therapeutic regimens in outcome efficacy.
