Non-Hodgkin lymphomas are other lymphomas that do not fit the criteria for Hodgkin lymphoma. They are characterised by painless lymphadenopathy or an abdominal or testicular mass. B-symptoms may not be present. Compared to Hodgkin lymphoma, they tend to present at an advanced stage.

The median age of diagnosis is 67 years.

Notable Non-Hodgkin lymphomas

Non-hodgkin lymphoma	Translocation	Effect	Cluster of Differentiation
Burkitt lymphoma	t(8;12)	c-MYC activation
Mantle cell lymphoma	t(11;14)	Cyclin-D1 overexpression	CD5+, C20+
Follicular lymphoma	t(14;18)	bcl-2 overexpression	CD10+, CD19+, CD20+
Marginal zone lymphoma	t(11;18)

Non-Hodgkin lymphomas
- Small Lymphocytic Lymphoma (SLL/CLL)
- Follicular lymphoma (predominantly small cell)
- Diffuse Large B-cell lymphoma (DLBCL)
- Burkitt Lymphoma (BL)
- High-grade B-cell Lymphoma (Small non-cleaved) Burkitt-like lymphoma
- Precursor T or B-cell lymphoblastic Lymphoma or Leukemia (Lymphoblastic lymphoma)
- Mantle cell lymphoma
- Marginal zone lymphoma
Risk factors for Non-Hodgkin lymphoma
- Older age (67 years)
- Male sex (1.5:1 M:F)
- Autoimmune disease (SLE, Sjogren syndrome, celiac disease)
- EBV
- HIV/AIDs – especially CNS lymphomas
- Exposure to pesticides, herbicides, benzene and hair-dye
- History of chemotherapy and radiation
- Genetic disorders
  - Down syndrome
  - Klinefelter syndrome
  - Hereditary immunodeficiency
Investigations
- Excisional biopsy
- Whole body PET scan and Bone marrow biopsy for staging
- Hepatitis serology before chemotherpay induction
Treatment
- Psychological support
- Chemotherapy with R-CHOP
  - Rituximab → sudden death, tumor lysis syndrome (test for HepB before starting, for CD20+ malignant cells)
  - Cyclophosphamide → hemorrhagic cystitis
  - Daunorubicin → Dilated cardiomyopathy
  - Oncovin → peripheral neuropathy
  - Prednisone → Cushing syndrome
- Methotrexate if there is CNS involvement
- Prevention and treatment of tumour lysis syndrome
