Disease Profile

Follicular lymphoma

Prevalence
Prevalence estimates on Rare Medical Network websites are calculated based on data available from numerous sources, including US and European government statistics, the NIH, Orphanet, and published epidemiologic studies. Rare disease population data is recognized to be highly variable, and based on a wide variety of source data and methodologies, so the prevalence data on this site should be assumed to be estimated and cannot be considered to be absolutely correct.

Inheritance

Autosomal dominant A pathogenic variant in only one gene copy in each cell is sufficient to cause an autosomal dominant disease.

Autosomal recessive Pathogenic variants in both copies of each gene of the chromosome are needed to cause an autosomal recessive disease and observe the mutant phenotype.

X-linked
dominant X-linked dominant inheritance, sometimes referred to as X-linked dominance, is a mode of genetic inheritance by which a dominant gene is carried on the X chromosome.

X-linked
recessive Pathogenic variants in both copies of a gene on the X chromosome cause an X-linked recessive disorder.

Mitochondrial or multigenic Mitochondrial genetic disorders can be caused by changes (mutations) in either the mitochondrial DNA or nuclear DNA that lead to dysfunction of the mitochondria and inadequate production of energy.

Multigenic or multifactor Inheritance involving many factors, of which at least one is genetic but none is of overwhelming importance, as in the causation of a disease by multiple genetic and environmental factors.

Orpha Number: 545

Definition
Follicular lymphoma is a form of non-Hodgkin lymphoma (see this term) characterized by a proliferation of B cells whose nodular structure of follicular architecture is preserved.

Epidemiology
Prevalence of follicular lymphoma is estimated at about 1/3,000.

Clinical description
The median age at diagnosis is 60-65 years. The disease is extremely rare in children. Follicular lymphoma is located primarily in the lymph nodes, but can also involve the spleen, bone marrow, peripheral blood and Waldeyer's ring. The skin and central nervous system are affected in rare cases. Symptoms appear at an advanced stage of the disease and can include fever, night sweats and weight loss. At diagnosis, patients usually present with adenopathy and, in 50% of cases, splenomegaly.

Etiology
In 85% of cases, follicular lymphomas are associated with a translocation t(14;18) (q32;q21), which activates the BCL2 gene encoding the BCL2 protein that is essential for some apoptosis processes.

Diagnostic methods
Diagnosis is based on histological analysis of the adenopathy, a complete blood count, measurement of lactate dehydrogenase (LDH) and biopsy analysis of a lymph node. Examination using imagery (particularly a chest radiograph) is required. The observation of the translocation t(14;18) by polymerase chain reaction (PCR), in addition to suggested histological results, confirms the diagnosis.

Differential diagnosis
Differential diagnoses include chronic lymphocytic B cell leukemia, diffuse large B cell lymphoma, mantle cell lymphoma and MALT lymphoma (see these terms).

Management and treatment
If the lymphoma is localized it should be treated by radiotherapy. In the case of advanced stage lymphoma, chemotherapy with immuno-chemotherapy should be offered (rituximab combined with CHOP). In cases of chemosensitive relapse, treatment can be intensified.

Prognosis
The survival rate at five years is 80-90% and medial survival is approximately 10-12 years.

Symptoms

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.
