Brief summary

The goal of this infrastructure grant is to establish and maintain a cohort of over 12,000 non-Hodgkin lymphoma (NHL) patients to support broad and cutting-edge research that identifies clinical (including co-morbid diseases), epidemiologic (including lifestyle and other exposures), host genetic, tumor, and treatment factors, as well as the interaction among these factors, on short and long-term outcomes. These efforts will identify new approaches to improve the survival and well-being of NHL patients.

Detailed description

Newly diagnosed non-Hodgkin lymphoma (NHL) patients will be recruited from each center participating in the LEO cohort. At time of consent, participants will be asked to completed several questionnaires collecting health history, current medical and quality of life questions. Patients will also provide a baseline blood sample that will processed locally and stored centrally for future research use. Additionally, consent is given for use of excess clinical tumor tissue for research use.
