Epidemiology of Chronic Lymphocytic Leukemia Study

The Epidemiology of Chronic Lymphocytic Leukemia study is research led by Dr. Slager to help identify new genes that are responsible for chronic lymphocytic leukemia (CLL) and to understand whether these genes are influenced by environmental factors. The study is especially interested in enrolling people of color and minority populations because of a historical gap in diverse representation in CLL research.

Dr. Slager discusses the study and minority representation with the CLL Society

Study requirements

You don't need to visit a Mayo Clinic site in person to participate in the Epidemiology of Chronic Lymphocytic Leukemia study. The study pays for any costs associated with participation, including blood draws, and sends related questionnaires directly to you.

Visit the study website for more details and requirements.

Participation in the study includes:

  • Completing a questionnaire about lifestyle factors, personal medical history and demographic information.
  • Donating a small amount of blood, about 4 tablespoons. For convenience, our lab can send a kit that you can take to your local clinic or health care provider for the blood draw. The blood draw can also be done at Mayo Clinic if preferred.
  • Donating a sample of saliva. A kit is mailed to you with all the items to collect the sample.
  • Providing permission with written informed consent to access, for research purposes only, any medical records related to care for blood or lymph node cancer or related conditions.
  • Updating information and samples. Every three years, we contact study participants for a new blood sample and to complete a short questionnaire.
