Angioimmunoblastic T Cell Lymphoma: Causes, Symptoms, and Treatment
Medically reviewed by Achuta Uppu, MD, Internal Medicine. Last reviewed: October 23, 2026.
What kind of doctor treats Angioimmunoblastic T Cell Lymphoma?
A hematologist-oncologist (a doctor who treats blood cancers) usually treats angioimmunoblastic T-cell lymphoma, also called AITL. A pathologist (a doctor who examines cells under a microscope) confirms the diagnosis. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is angioimmunoblastic T-cell lymphoma?
Lymphoma is a cancer of a part of the immune system called the lymph system. Non-Hodgkin lymphomas begin when a type of white blood cell, called a T cell or B cell, becomes abnormal.
AITL is a T-cell lymphoma, so it starts in T cells. It belongs to a group called nodal lymphomas of T follicular helper cell origin. These start in a kind of T cell that helps other immune cells. AITL is the most common of this group. It is the second most common subtype of peripheral T-cell lymphoma (PTCL), lymphomas that start in mature T cells.
T-cell lymphomas make up less than 15% of non-Hodgkin lymphoma cases. Most PTCLs are considered aggressive, which means they grow quickly. AITL often progresses quickly. Treatment often works at first, but the lymphoma tends to come back (recur).
Symptoms
AITL often involves the lymph nodes and bone marrow. The spleen or liver can become enlarged.
Patients often have:
- Large swollen lymph nodes.
- Fever.
- Night sweats.
- Weight loss without trying.
- Skin rash.
Weakness and tiredness that do not go away, coughing, or trouble breathing can also happen. People with AITL often develop infections. This is because the disease causes an underlying immune deficiency, a weak immune system.
Causes and who gets it
Most of the time, doctors do not know why a person gets non-Hodgkin lymphoma. You are at increased risk if you have a weakened immune system or have certain types of infections.
AITL is more common in older adults. B-cell Epstein-Barr virus genomes are detected in most affected patients. Doctors also often find changes in genes, the body's instructions for cell growth. Examples are TET2, IDH2, and DNMT3A.
How doctors diagnose it
Doctors diagnose lymphoma with a physical exam and blood tests, and they confirm it with a biopsy. This means removing a lymph node and checking its cells under a microscope. A PET scan (a scan that shows active areas in the body) can show how far the lymphoma has spread. CT scans can help too. Doctors may also do a bone marrow biopsy when it would change treatment.
Treatment
Combination chemotherapy, which means several cancer drugs given together, is commonly used for AITL. When the cancer cells carry a marker called CD30, adding the targeted drug brentuximab vedotin to chemotherapy is the proposed standard of care. A targeted drug acts on specific cells.
If the lymphoma comes back, doctors may try other drugs. They may also use high-dose chemotherapy with stem cell support, which means infusing blood-forming cells after strong treatment. This has been described only in anecdotal reports, meaning a few cases rather than large studies.
Clinical trials, research studies that test new treatments, may also be an option. Ask your cancer doctor what fits your case.
When to see a doctor
See a doctor if you have swollen lymph nodes, unexplained weight loss, fever, or soaking night sweats. Call 911 or go to the emergency room if you have trouble breathing or chest pain.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Your doctor can check symptoms like fever or swollen lymph nodes and can refer you to a hematologist-oncologist. During treatment, your doctor can help watch for infections and manage everyday health needs.
Common questions
Does angioimmunoblastic T-cell lymphoma grow quickly?
Yes. This lymphoma often progresses quickly. Most PTCLs are considered aggressive, which means they grow quickly. Treatment often works at first, but the lymphoma tends to come back (recur).
What is the outlook for people with AITL?
One project that followed 243 patients with AITL found a 5-year overall survival rate of 33%. That number is the share of patients alive 5 years after diagnosis.
Who is more likely to get AITL?
AITL is more common in older adults. Most of the time, doctors do not know why a person gets non-Hodgkin lymphoma. Having a weakened immune system or certain infections raises the risk.
How do doctors confirm AITL?
Doctors remove a lymph node and check its cells under a microscope. This is called a biopsy. A PET scan (a scan that shows active areas in the body) can show how far the lymphoma has spread.
