Lymphoma affects the lymphatic system and B and T cell populations of white blood cells (WBCs). Lymphoma develops with the malignant transformation of lymphocytes. Most lymphomas originate from B cells with only 10–15% being of T and NK cell origins.1
What causes lymphoma?
As with many cancers, genetic alterations have been identified in several types of lymphoma and family history of the disease accounts for 5% of cases. Several factors are considered as risks promoting the development of lymphoma. These include radiation therapy, immune deficiency and viral infections such as from human immunodeficiency virus (HIV), human T lymphotropic virus type 1 (HTLV-1), hepatitis C virus (HCV) and Epstein-Barr virus (EBV).2
Types of lymphoma
More than 70 kinds of lymphomas have been described, and they are grouped in two main types—Hodgkin and non-Hodgkin lymphoma.
Hodgkin lymphoma
In most cases of Hodgkin lymphoma (HL), the neoplastic cells are derived from mature B-cells. It preferentially develops in young adults between 20 and 34 years old. Hodgkin Reed-Sternberg (HRS) cells are a hallmark of Hodgkin lymphoma. They are giant multinucleated cells forming a clonal tumor pool of Hodgkin lymphoma. CD30 is the hallmark of HL and HRS cell surface markers.3
Non-Hodgkin lymphoma
Non-Hodgkin lymphoma (NHL) is one of the most common forms of lymphoma.4 It preferentially develops in older adults and is less responsive to treatment than Hodgkin lymphoma.
