Mayo Clinic is committed to quality patient care, basic and translational research, and provides a portfolio of clinical trials that are dedicated to serve all patient cohorts who have CLL. Our investigations range from studies of both a basic and clinical translational nature for early stage to late stage disease, familial CLL and patients who have been diagnosed with monoclonal B-cell Lymphocytosis. In this way we hope to obtain and provide more information that will assist in counseling, prognosis and developing more effective treatments for our CLL patients.
