Klinik für Innere Medizin NON-HODGKIN’S LYMPHOMA (NHL) • Approximately 1.5 million people worldwide are living with non-Hodgkin’s lymphoma (NHL), and it is estimated that 300,000 people die each year from the disease • 1 new case diagnosed every 9 minutes* • 81% increase in incidence of NHL between 1973 -1990 • NHL is the third fastest growing cancer (excluding the US) in terms of population in the world • NHL is leading cause of death due to cancer in men aged 20-40 years *US *US statistics statistics 1 Proposed WHO Classification of Lymphoid Neoplasms B-Cell neoplasms Precursor B-cell neoplasm: Precursor B-lymphoblastic leukemia/lymphoma (precursor B-ALL) Mature (peripheral) B-cell neoplasms: B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma B-cell prolymphocytic leukemia Lymphoplasmacytic lymphoma Splenic marginal zone B-cell lymphoma (+/- villous lymphocytes) Hairy cell leukemia Plasma cell myeloma/plasmacytoma Extranodal marginal zone B-cell lymphoma of MALT type Nodal marginal zone B-cell lymphoma (+/- monocytoid B cells) Follicular lymphoma Mantle-cell lymphoma Diffuse large B-cell lymphoma Mediastinal large B-cell lymphoma Primary effusion lymphoma Burkitt's lymphoma/Burkitt cell leukemia Proposed WHO Classification of Lymphoid Neoplasms T-cell and NK-cell neoplasms Precursor T-cell neoplasm: Precursor T-lymphoblastic lymphoma/leukemia (precursor T-ALL) Mature (peripheral) T-cell neoplasms: T-cell prolymphocytic leukemia T-cell granular lymphocytic leukemia Aggressive NK-cell leukemia Adult T-cell lymphoma/leukemia (HTLV1+) Extranodal NK/T-cell lymphoma, nasal type Enteropathy-type T-cell lymphoma Hepatosplenic gamma-delta T-cell lymphoma Subcutaneous panniculitis-like T-cell lymphoma Mycosis fungoides/Sezary syndrome Anaplastic large-cell lymphoma, T/null cell, primary cutaneous type Peripheral T-cell lymphoma, not otherwise characterized Angioimmunoblastic T-cell lymphoma Anaplastic large-cell lymphoma, T/null cell, primary systemic type 2 Major NHL Types Category Percentage Incidence 31% 22% 8% 7% 7% 6% 2% 2% 2% 2% 2% Diffuse Large B Cell Follicular Marginal Zone B-Cell, MALT Peripheral T-cell Small B-lymphocytic (CLL) Mantle cell lymphoma Primary mediastinal large B-cell Anaplastic large T/null cell High grade B-cell, Burkitt-like Marginal Zone B-cell, nodal Precursor T-lymphoblastic Indolent Aggressive Highly aggressive Frequency of NHL Subtypes in Adults Composite lymphomas (12%) Small lymphocytic (6%) Follicular (22%) Mantle cell (6%) Peripheral T-cell (6%) Marginal zone B-cell, MALT (5%) Diffuse large B-cell (31%) Other subtypes with a frequency <2% (9%) Marginal zone B-cell, nodal (1%) Lymphoplasmacytic (1%) Armitage et al.
