Epidemiological Registry Describing Treatment Reality and Therapy Modalities of Patients With Malignant Lymphatic Systemic Diseases (Non-Hodgkin's Lymphoma, Chronic Lymphocytic Leukemia and Multiple Myeloma) Requiring Therapy.

The TLN is a prospective, longitudinal, nation wide cohort study with the purpose to record information on the antineoplastic treatment of lymphatic neoplasms in Germany. The registry will follow patients for up to five years. It will identify common therapeutic sequences and changes in the treatment of the disease. At inclusion, data in patient characteristics, comorbidities, tumor characteristics and previous treatments are collected. During the course of observation data on all systemic treatments, radiotherapies, surgeries, and outcome are documented.

The impact of nutrition (LyNut) and physical activity (LyNut) on the course of the adjuvant disease will be examined in patients with indolent and aggressive Non-Hodgin Lymphoma, as well as long-term effects of systemic treatment (LyTox) and quality of life (LyLife) in patients with multiple myeloma.
