Summary

This study follows up to 1,000 adults with chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), Waldenstrom macroglobulinemia, or related conditions to learn how these diseases progress over time. Participants receive no treatment as part of the study; instead, they have regular check-ups, blood draws, and optional tests like bone marrow biopsies every 6 to 24 months. The goal is to better understand the disease and find clues for future treatments.
