Study of Hodgkin's Lymphoma, Non-Hodgkin's Lymphoma and Chronic Lymphocytic Leukemia
Our lab's Mayo Clinic Case Control Study of Hodgkin's Lymphoma, Non-Hodgkin's Lymphoma and Chronic Lymphocytic Leukemia tests hypotheses about the etiology of these types of cancer.
Led by Dr. Cerhan, this study analyzes study participant data for:
- Medical history
- Pesticide exposures
- Farming exposures
- Early-life factors
- Genetic susceptibility
- Gene-by-environment interactions
Participants enrolled in the study were patients newly diagnosed with Hodgkin's lymphoma or non-Hodgkin's lymphoma, including chronic lymphocytic leukemia, from Minnesota, Iowa and Wisconsin who were seen at Mayo Clinic's campus in Rochester, Minnesota, from September 2002 through August 2014. Control participants were patients from the same region without a history of lymphoma or leukemia who had a prescheduled general medical examination at Mayo Clinic and were frequency matched on age, sex and residence of the case group.
Each participant donated a blood sample, and the lab banked serum, plasma and DNA. Participants also completed the Main Questionnaire, Farming and Pesticide Exposure Survey, Female History (for women), and the Food Frequency Questionnaire.
Although the case-control study is no longer recruiting participants, data analysis is ongoing.
The study has also been a major contributor to the International Lymphoma Epidemiology (InterLymph) Consortium, an open scientific forum for epidemiologic research in non-Hodgkin's lymphoma formed by the National Cancer Institute in 2001.
