Cancer Category/Type
Cancer Sub-Classification / Subtype
- Nodal Marginal Zone Lymphoma
Definition / Description of Disease
Nodal marginal zone lymphoma (NMZL) is an uncommon subtype of non-Hodgkin lymphoma. It is a primary nodal B-cell lymphoma with histological features similar to Splenic marginal zone lymphoma and Extranodal marginal zone lymphoma involving lymph nodes, but without evidence of splenic or extranodal disease[1].
Synonyms / Terminology[1]
- Monocytoid B-cell lymphoma
- Parafollicular B-cell lymphoma (no longer in use)
Epidemiology / Prevalence[1][2][3]
- 1.5-1.8% of all lymphoid neoplasms
- Median age ~60 years old
- Both sexes are affected equally
- Cases also occur in children and are separately diagnosed as HAEM5:Paediatric nodal marginal zone lymphoma
- Association with autoimmune diseases
- Association with Hepatitis C virus infection reported in some studies but not all studies
Clinical Features
- Asymptomatic, localized or generalized lymphadenopathy
- B symptoms (fever, night sweats, and weight loss)
- Bone marrow involvement
The presence of a primary extranodal marginal zone lymphoma should be ruled out due to the possibility of a nodal dissemination of a MALT lymphoma occurring in patients with a history of Sjogren syndrome and Hashimoto thyroiditis[1].
Sites of Involvement
- Lymph nodes
- Bone marrow
- Peripheral blood
Morphologic Features[1]
- Variable populations of lymphoma cells
- Centrocyte-like and monocytoid B-cells
- Plasma cells
- Scattered transformed B cells
- Lymph nodes show small lymphoma cells surrounding reactive follicles (marginal zone distribution)
- Extension to interfollicular areas and follicular colonization may be present
- Diffuse or partial nodal effacement may be present
- Bone marrow shows lymphoma cells in interstitial, nodular, intertrabecular or paratrabecular distribution
Immunophenotype
| Finding | Marker |
|---|---|
| Positive (B-cell lineage markers) | CD19, CD20, CD22, PAX5, FMC7, CD79a, sIg |
| Positive (most cases) | BCL2, MNDA, IRTA1 |
| Variable positivity | CD5, CD43, CD23 |
| Negative | CD10, Cyclin D1, BCL6, LMO2 |
Chromosomal Rearrangements (Gene Fusions)
- Recurrent chromosomal translocations that are frequent in other lymphoid malignancies and associated with extranodal MZL are not detected[1][4].
Characteristic Chromosomal Aberrations / Patterns[1][4]
- Deletions in 7q31
Genomic Gain/Loss/LOH[1]
| Chromosome Number | Gain/Loss/Amp/LOH | Region |
|---|---|---|
| 3 | Gain | N/A |
| 12 | Gain | N/A |
| 18 | Gain | N/A |
| 6 | Loss | 6q23-24 |
Gene Mutations (SNV/INDEL)
Whole-exome sequencing (WES) study have identified mutations involved in NOTCH, nuclear factor κB (NF-κB), B-cell receptors and toll like receptor pathways . In one study, 16% (4/25) of cases identified a BRAF (V600E) mutation with associated strong IgD expression. In one of the four BRAF positive mutation, two non-hotspot mutations were detected (L597Q and N581I) which was previously found in BRAF V600 wild-type melanoma. In the same study, mutations of KMT2D (7/25, 28%), TET2 (5/25, 20%), and EZH2 (5/25, 20%) were among the more frequent mutated genes. CREBBP, TNFRSF14, FAS, TNFAIP3, KLF2, and CXCR4 mutations were also detected[4]. In another study, which investigated genetic lesions in 35 patients with NMZL, PTPRD mutations were found in 14.3% (5/35) of patients and PTPRD locus deletions were found in 5.7% (2/35) of patients[5]. Mutations were also identified in another study for NFKBIE and ITPR2 mutations involved in the NF-κB pathway and B-cell receptor mediated calcium signal pathway. However, in this study they did not find any PTPRD mutations or BRAF mutations, demonstrating the diverseness of the disease[6]. No BRAF mutations have yet to be identified in other studies on NMZL[4].
Other Mutations
Immunoglobulin genes are clonally rearranged consisting of mutated IGHV3 and IGHV4 family members, particularly IGHV4-34 and cases associated with hepatitis C use IGHV1-69[1].
Epigenomics (Methylation)
- Not known in this specific subtype.
Genes and Main Pathways Involved
- NF-κB pathway and B-cell receptor mediated calcium signal pathway.
Diagnostic Testing Methods
- No diagnostic test is specifically established.
Clinical Significance (Diagnosis, Prognosis and Therapeutic Implications)
- None.
Familial Forms
- Not known in this specific subtype.
Other Information
None
