Characterization of patients with Chronic Lymphocytic Leukemia in British Columbia, Canada using a province-wide CLL database

Trial description: The aim of this study is to characterize current treatment patterns for Chronic Lymphocytic Leukemia (CLL) in first-line treatment setting and to compare the patient characteristics based on the type of regimens they received in this setting in British Columbia (BC) and to characterize the broader treatment patterns for CLL patients in BC including second line and further therapies in a well defined cohort of patients with diagnosis from 2003 to 2012. Currently there are few good therapies available for those who are not suitable for standard fludarabine-based treatment, however this situation is changing, and with the advent of newer therapies, including ofatumumab, the patient group who is fludarabine non-suitable, or others may benefit from these therapies. It will therefore be important to know the baseline proportions of patients treated with different first and subsequent therapy, and their outcomes, so that accurate predictions and comparisons will be possible once these newer therapies are available.
