What is the survival rate of marginal zone lymphoma?

What is the survival rate of marginal zone lymphoma?

It is estimated that there are 1000 to 2300 cases per year in the US. Five-year survival rates are reported as follows: 88.7 percent for MALT, 79.7 percent for splenic MZL, 76.5 percent for nodal MZL.

What does marginal zone lymphoma mean?

Marginal zone lymphomas are types of slow-growing (low-grade) non-Hodgkin lymphomas that develop from B cells. They are called marginal zone lymphomas because they develop in a particular region found at the edge of normal lymphoid tissues (collections of lymphocytes) called the marginal zone.

Is marginal zone lymphoma always a cancer?

Lymphoma is a cancer that starts in the lymphatic system. The lymphatic system is a network of tissues and organs that remove waste and toxins from the body. Lymphoma includes Hodgkin’s and non-Hodgkin’s lymphoma.

How does marginal zone lymphoma progress?

Marginal zone lymphoma (MZL) develops slowly and, in most cases, it responds well to treatment (remission). However, this is an indolent lymphoma, and this means that it often relapses (comes back). If the lymphoma does relapse it can usually be treated again to keep it under control.

Is marginal zone lymphoma curable?

Most patients with nodal marginal zone lymphoma present with advanced stage disease and are not likely to achieve cure, even with aggressive chemotherapy regimens. Moreover, there is little evidence that choice of initial therapy has any impact on survival.

Is marginal zone lymphoma aggressive?

Rarely, marginal zone lymphoma can transform into a more aggressive lymphoma, typically DLBCL. These patients require aggressive therapy and may benefit from autologous stem cell transplantation. Although the aggressive subtype may resolve completely, patients are often left with a persistent low-grade lymphoma.

Is nodal marginal zone lymphoma curable?

The clinical outcome of NMZL patients is similar to that of other nodal indolent lymphomas. To date, the disease has not proven curable with classical chemotherapy and is characterized by a continuous pattern of relapses.

What treatment is used for marginal zone lymphoma?

Common initial treatments are bendamustine (Treanda) plus rituximab and R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone), which are used to treat other slow growing lymphomas such as follicular lymphoma.

Is marginal zone lymphoma treatable?

Can marginal zone lymphoma transform?

Incidence of MZL transformation HGT of MZL, usually to DLBCL, is a rare event occurring in 3.8\% to 13\% of patients, though, some series in SMZL report transformation in up to 19\% (6,8,59,69,71-76).

What does lymphoma, B-cell, Marginal zone mean?

Marginal zone lymphomas are typically slow-growing B-cell lymphomas that comprise 5-10\% of lymphoma cases . There are three distinct types, largely based on initial sites of involvement: MALT lymphoma (extranodal marginal zone B-cell lymphoma or mucosa-associated lymphoid tissue lymphoma) This is the most common type of MZL.

What is marginal zone B cell lymphoma?

Marginal zone lymphoma is an indolent (slow-growing) type of B-cell non-Hodgkin lymphoma that arises from marginal zone B-cells present in lymph nodes and certain other tissues outside of lymph nodes. 1,2 In MZL, abnormal B cells grow out of control and may crowd out healthy cells. 1

What is cutaneous marginal zone lymphoma?

Primary cutaneous marginal zone lymphoma is a type of low-grade cutaneous B-cell lymphoma originating from the mucosa -associated lymphoid tissue (MALT). It is a heterogeneous proliferation of marginal zone cells, B cells, small lymphocytes, and plasma cells. Who gets primary cutaneous marginal zone lymphoma?

What is T zone lymphoma?

T-zone lymphoma is so named for its involvement in a specific area of the lymph node that consists of a dense accumulation of T-cells. Lympho-epithelioid lymphoma, also called Lennert’s lymphoma, is rare and generally affects older individuals.
