Understanding R/R Follicular Lymphoma
Relapsed/refractory (r/r) follicular lymphoma (FL)
What is r/r FL?
Follicular lymphoma is a type of non-Hodgkin lymphoma (cancer of the immune system) that develops from B cells and is usually slow growing.
The immune system is made up of different cells and organs that work together to protect the body from diseases. For example, there are B cells*, T cells†, and glands called lymph nodes. Sometimes the cells inside a lymph node can grow abnormally and become cancerous.
When the cancer is in remission, it means the signs and symptoms of cancer have decreased or disappeared. It does not mean the cancer is cured. The cancer is considered to have relapsed when it comes back after a period of remission and is considered refractory when it does not respond to treatment.

*B cells: Along with other cells, they make up your body’s immune system. They defend the body by producing antibodies.
†T cells: Along with other cells, they make up your body’s immune system. They are natural defenders that detect and destroy possible threats such as infected or cancerous cells.
‡Antibodies: Proteins made by your B cells that help to protect the body against infection.
Signs and symptoms of relapsed or refractory FL
The signs and symptoms of r/r FL are usually similar to those that occur upon first diagnosis, such as:
Swelling in the neck, underarms, or groin
Fatigue (tiredness)
Night sweats and chills
Weight loss
How common is relapsed or refractory FL?
Around 1 in 5 of people with FL will experience relapse within 2 years after initial treatment. With aging, the possibility of relapse often increases. Older patients may also have a higher risk of refractory disease.
How to talk about having cancer with loved ones
Telling your friends and family about your cancer can help them support you – not just at the time of diagnosis, but throughout your treatment journey. The first conversation you have may be difficult, so tell them in the way that feels best for you – it could be face to face, over the phone, or by email.
Visit the Patient Support section for further support.
Caring for a loved one with FL
Finding out your loved one’s cancer has returned or hasn’t responded to treatment can be hard on everyone’s mental and emotional well-being. Family and friends play an important role in their treatment experience. Visit the Patient Support section for more information on how best to support your loved one during this time.
