What is a peripheral T-cell?
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 (NK) cells. PTCL is classified as a subtype of non-Hodgkin’s lymphoma (NHL).
What is the symptoms of Angioimmunoblastic T-cell lymphoma?
Symptoms of AITL include high fever, night sweats, skin rash, and autoimmune disorders such as autoimmune hemolytic anemia (AIHA) and immune thrombocytopenia (ITP). As a result of these autoimmune disorders, the body’s immune system attacks its own cells and tissues, such as red blood cells (AIHA) or platelets (ITP).
What is the cause of T-cell lymphoma?
Adult T-cell leukemia/lymphoma: This lymphoma is caused by infection with a virus called HTLV-1. It is rare in the United States, and much more common in Japan, the Caribbean, and parts of Africa – where infection with HTLV-1 is more common.
Can PTCL be cured?
PTCL is potentially curable with chemotherapy. The median progression free survival (PFS) following CHOP chemotherapy is 12 to 14 months. Approximately 20 to 30% of patients will be alive, and disease free, 5 years after the completion of treatment.
What is the difference between B cell lymphoma and T-cell lymphoma?
While B cells produce the antibodies that target diseased cells, T cells directly destroy bacteria or cells infected with viruses. This type of lymphoma is a fast-growing disease that is treated more like acute leukemia.
Is AITL curable?
In general, relapsed lymphoma remains potentially curable; however, required approaches are significantly more aggressive and therefore riskier than the initial treatment. AITL cure remains elusive in the majority of patients.
What does Angioimmunoblastic mean?
Listen to pronunciation. (AN-jee-oh-IH-myoo-noh-BLAS-tik T-sel lim-FOH-muh) An aggressive (fast-growing) type of T-cell non-Hodgkin lymphoma marked by enlarged lymph nodes and hypergammaglobulinemia (increased antibodies in the blood).
What is Angioblastic lymphoma?
AITL is a type of peripheral T-cell lymphoma. It is a high grade (aggressive) lymphoma that affects blood cells called T cells. High grade lymphomas tend to grow more quickly than low grade lymphomas. AITL usually affects older people, typically around the age of 70.
How is PTCL diagnosed?
The diagnosis of PTCL-NOS is made based on the presence of typical histopathological features of lymphoma, an aberrant T-cell immunophenotype, often with a loss of CD5 and CD7, and a clonal T-cell receptor (TCR) gene rearrangement, in the appropriate clinical context.
