Non-Hodgkin lymphoma (NHL), also known as non-Hodgkin's lymphoma, is a group of blood cancers that includes all types of lymphomas except Hodgkin lymphomas. [1] Symptoms include enlarged lymph nodes, fever, night sweats, weight loss, and tiredness. [1] Other symptoms may include bone pain, chest pain, or itchiness. [1]
Primary cutaneous diffuse large B-cell lymphoma, leg type is an aggressive B-cell lymphoma that is often resistant to therapy and carries a poor prognosis, [5] i.e., they have a 5-year disease-specific survival rate of 43% or 70% depending on whether their cancer cells have or do not have, respectively, inactivating mutations in both of their ...
Histopathology of diffuse large B-cell lymphoma occurring in the tonsil. H&E stain. Lymphoproliferative disorders (LPDs) refer to a specific class of diagnoses, comprising a group of several conditions, in which lymphocytes are produced in excessive quantities. These disorders primarily present in patients who have a compromised immune system.
Anaplastic large cell lymphoma (ALCL) is a subtype of mature T-cell lymphoma involving T-cells or natural killer (NK) cells, representing 12% of patients. [9] It can be recognized by a constant expression of the tumour receptor necrosis factor CD30 , a membrane protein expressed by activated T and B cells, in the cancer cells. [ 13 ]
Mantle cell lymphoma (MCL) is a type of non-Hodgkin's lymphoma, comprising about 6% of cases. [1] [2] It is named for the mantle zone of the lymph nodes where it develops.[3] [4] The term 'mantle cell lymphoma' was first adopted by Raffeld and Jaffe in 1991.
A study in Japan found that approximately 26% of relapsed B-cell lymphoma patients lost CD20 expression during treatment with rituximab. Lab tests involving 5-Aza showed that CD20 expression and rituximab sensitivity could be restored in some cases using epigenetic drug treatment. [10] Rituximab (Rituxan. The mechanism of action of Rituximab ...
Subtypes of T-cell lymphoma [1]. Peripheral T-cell lymphoma not otherwise specified (PTCL-NOS), is a subtype of peripheral T-cell lymphoma.Peripheral T-cell lymphoma (PTCL) is defined as a diverse group of aggressive lymphomas that develop from mature-stage white blood cells called T-cells and natural killer cells (see figure for an overview of PTCL subtypes).
May progress to follicular lymphoma or mantle cell lymphoma; may be associated with the development of certain other lymphoid malignancies: Duration: Chronic: Types: In situ follicular lymphoma; in situ mantle cell lymphoma: Treatment: Follow-up tests for the development of follicular or mantle cell lymphoma, or other lymphoid malignancies
