Second Cancer Incidence Among Chronic Lymphocytic Leukemia (CLL) Patients: A French Population-Based Study

Introduction. The risk of developing a second primary cancer (SPC) is increased in patients with CLL. The mechanisms explaining this association could be related to lifestyle, environment, host factors or interactions or other influences. We conducted an epidemiological study based on 10 French registries and evaluated the risk of developing SPC in patients with CLL.
