Nodal Marginal Zone Lymphoma

Nodal Marginal Zone Lymphoma (NMZL) is an indolent B-cell lymphoma that is found mostly in the lymph nodes. The disease is rare and only accounts for 1% of all Non-Hodgkin’s Lymphomas (NHL). It is most commonly diagnosed in older patients, with women more susceptible than men.

The disease is classified as a marginal zone lymphoma because the mutation occurs in the marginal zone of the B-cells. Due to its confinement in the lymph nodes, this disease is also classified as nodal.

Diagnosis and Staging

Symtoms include:

• Painless swelling of the lymph nodes
• Fever
• Night sweats
• Fatigue
• Weight loss

Diagnosis is made using a lymph node biopsy. Other tests, such as X-rays, CT scan, PET scan, ultrasound, and bone marrow biopsy are used to stage the disease. Staging is as follows:

Stage I

Only one group of lymph nodes is involved,

Stage II

Two groups of lymph nodes are involved, but they are on the same side of the diaphragm.

Stage III

Lymph nodes on both sides of the diaphragm are involved. The spleen is considered a lymph node in this staging system, so its involvement marks stage III.

Stage IV

The bone marrow, liver, or other organs are involved.

Most patients are diagnosed in the earlier stages of disease.
