Marginal Zone Lymphoma
Marginal zone lymphomas are a group of indolent (slow-growing) NHL B-cell lymphomas, which account for approximately 12 percent of all B-cell lymphomas. The median age for diagnosis is 65 years old.
There are three types of marginal zone lymphoma:
Extranodal marginal zone lymphoma or mucosa-associated lymphoid tissue (MALT) is the most common form of marginal zone lymphoma. It occurs outside the lymph nodes, in places such as the stomach, small intestine, salivary gland, thyroid, eyes, and lungs. MALT lymphoma is divided into two categories: gastric, which develops in the stomach, and non-gastric, which develops outside of the stomach. This form of lymphoma makes up about nine percent of all B-cell lymphomas.
In many cases of MALT lymphoma, there is a previous medical history of inflammation or autoimmune disorders. For example, Helicobacter pylori (H. pylori), a microbial pathogen linked to chronic gastritis, has been associated with a significant portion of patients with gastric MALT lymphoma.
Nodal marginal zone lymphoma (sometimes called monocytoid B-cell lymphoma) occurs within the lymph nodes and accounts for about two percent of all B-cell lymphomas.
Splenic marginal zone lymphoma occurs most often in the spleen and blood. It has been associated with Hepatitis C. This form of lymphoma makes up about one percent of all B-cell lymphomas.
The type of treatment selected for a marginal zone lymphoma patient depends on the stage of disease, the age of the patient, the patient's overall health, any signs or symptoms related to the lymphoma, and the location of the disease.
Treatment Options for Gastric MALT
Treatment Options for Non-gastric MALT
Treatment Options for Nodal Marginal Zone Lymphoma
Treatment Options for Splenic Marginal Zone Lymphoma
• B-cell receptor signaling blockers
• Ibritumomab tiuxetan (Zevalin)
It is critical to remember that today's scientific research is continuously evolving. Treatment options may change as new treatments are discovered and current treatments are improved. Therefore, it is important that patients check with LRF or with their physician for any treatment updates that may have recently emerged.
Survivors and their caregivers are encouraged to keep copies of all medical records and test results as well as information on the types, amounts, and duration of all treatments received. This documentation will be important for keeping track of any effects resulting from treatment or potential disease recurrences. For further information, please review our fact sheet on survivorship issues.
A lymphoma diagnosis often triggers a range of feelings and concerns. In addition, cancer treatment can cause physical discomfort. Support groups and online message boards can help patients connect with other people who have lymphoma. One-to-one peer support programs, such as LRF's Lymphoma Support Network, match lymphoma survivors (or caregivers) with volunteers who have gone through similar experiences.
LRF offers a wide range of resources that address treatment options, the latest research advances, and ways to cope with all aspects of lymphoma. LRF also provides many educational activities, from in-person meetings to teleconferences and webcasts.
