Key points
- Diffuse large B-cell lymphoma grows quickly, but it is curable: in most patients the disease does not come back after the first treatment [24, 1, 5].
- The first treatment for most patients is the R-CHOP regimen: the antibody rituximab with four other drugs, usually 6 cycles, one every 3 weeks [1, 3].
- In advanced, higher-risk disease, the newer Pola-R-CHP regimen lowered the chance of relapse slightly, but did not clearly lengthen life [6, 1].
- If the disease comes back more than a year later, more chemotherapy followed by a transplant of the patient's own stem cells can still cure it [1, 9].
- If it comes back within a year, or does not respond to the first treatment, CAR-T cell therapy has done better than a transplant; for a third treatment and beyond there are also bispecific antibodies [1, 12, 13, 17].
The story of treating this lymphoma: from CHOP to R-CHOP
Diffuse large B-cell lymphoma, a cancer of white blood cells called "B lymphocytes", is the most common type of non-Hodgkin lymphoma; about one in three lymphomas in adults is of this type [24, 1]. It grows quickly and usually shows itself with swollen lymph nodes, fever, drenching night sweats or weight loss [24]; see the symptoms in What are the symptoms of lymphoma?.
Until about 2000, the main treatment was a combination of four chemotherapy drugs called CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone). In advanced disease, it cured about 3 in every 10 patients [2]. For years doctors designed heavier combinations, but in a large study in 1993 none of them was better than CHOP, and they caused more deaths from side effects [2].
The big step forward came from an antibody: rituximab, which sticks to a protein called CD20 on B cells [3]. In 2002, a study in patients aged 60 to 80 showed that adding rituximab to CHOP made the disease disappear completely in more patients and lengthened life, without clearly adding important side effects [3]. Ten years later, about one and a half times as many patients were alive in the rituximab group as in the CHOP-only group [4].
Since then, R-CHOP has been the standard first treatment, and it cures about 6 in every 10 patients [5, 1]. Efforts to improve it continued, and the newer Pola-R-CHP regimen, described below, lowered the chance of relapse slightly in a group of patients [5, 6]. The next big advances were mostly for patients whose disease comes back: stem cell transplant, CAR-T cell therapy and bispecific antibodies [9, 12, 17].
Treatment today, step by step
- 1
Biopsy and finding out how far the disease has spread
The diagnosis is made by taking a sample (biopsy) of a lymph node and examining it in a specialist laboratory. A PET scan shows how far the disease has spread and later measures the response to treatment [1]. A few simple factors, such as age, stage and a blood test (LDH), show how serious the disease is [1].
- 2
First treatment: R-CHOP
Rituximab and four other drugs, given as infusions on one day plus 5 days of prednisone tablets, every 3 weeks [5]. Most patients have 6 cycles (about 4 months); in limited disease without risk factors, 4 cycles are enough [1]. See: The R-CHOP regimen and How many sessions of chemotherapy are there?
- 3
Advanced disease with higher risk: Pola-R-CHP
In this regimen, the targeted drug polatuzumab vedotin takes the place of vincristine. In patients at intermediate or high risk, it lowered the chance of relapse slightly, but there was no clear difference in length of life [6]. The European guideline suggests it for stage 3 or 4 disease with two or more risk factors and considers R-CHOP an acceptable alternative [1]. See: The Pola-R-CHP regimen

Is treatment needed to prevent spread to the brain?
Sometimes lymphoma comes back in the brain or spinal cord after treatment. Fortunately this risk is low in most patients: nearly 9 in every 10 patients fall into the low- or intermediate-risk groups. In the small high-risk group, about 1 in every 10 people develops this problem within two years [7]. Your doctor estimates your risk with a simple score (which also takes into account involvement of the kidney or adrenal gland) [7].
For years, high-risk patients were given high-dose methotrexate to prevent this kind of relapse. But in a large study of more than 2,000 high-risk patients, this did not clearly lower the risk [8]. This is why the European guideline says the benefit of this prevention is still uncertain; in high-risk patients, a brain MRI and a test of the spinal fluid are recommended [1]. Make the decision with your specialist.
If the disease comes back: transplant or CAR-T?
In about 3 to 4 in every 10 patients, the disease comes back after the first treatment or does not respond to it [1]. This is not the end of the road. The most important point in choosing the next treatment is when the disease came back: less or more than a year after the first treatment [1]. A new biopsy is recommended before the second treatment [1].
Relapse after more than a year: more chemotherapy and a transplant
First, a few more cycles of chemotherapy with rituximab. If the disease responds, high-dose chemotherapy followed by a transplant of the patient's own stem cells [1]. Since 1995 this approach has been shown to lengthen patients' lives [9], and it is still the standard treatment for late relapse [1, 10].
Relapse within a year, or no response: CAR-T
When the disease comes back early, chemotherapy and transplant work less well [10]. In CAR-T cell therapy, the patient's own immune cells (T cells) are collected from the blood, changed in a laboratory so that they recognise the lymphoma cells, and given back to the patient once [20]. In two large studies, CAR-T controlled the disease much better than chemotherapy and transplant, and in one of them it also lengthened patients' lives [12, 13, 14]. The European guideline considers it the main treatment for this group [1].
When intensive treatment is not possible
Another relapse: bispecific antibodies
These antibodies stick to a lymphoma cell with one arm and to one of the patient's immune cells with the other, bringing the two together. In patients who had been treated twice or more, even after CAR-T, glofitamab and epcoritamab made the disease disappear completely on scans in about 4 in every 10 patients [17, 18]. For a third treatment and beyond, CAR-T (if you have not had it before) and these antibodies are the best options [1].
- "What stage is my disease and how many risk factors does it have?" [1]
- "Is R-CHOP or Pola-R-CHP better for me?" [1, 6]
- "Is my risk of the lymphoma coming back in the brain high?" [7]
- "Have I been tested for hepatitis B before rituximab?" [22]
- "If the disease comes back, would a transplant or CAR-T be suitable for me?" [1]
When should I call my doctor?
During chemotherapy: report a temperature of 38 °C or higher, chills or any sign of infection straight away; infection during this time can be dangerous [23]. See: Low blood counts and preventing infection. With rituximab: a hepatitis B test is needed before starting; report worsening tiredness or yellowing of the skin or eyes straight away [22]. After CAR-T: report fever, chills, a racing heart, dizziness or low blood pressure, breathlessness, confusion, shaking hands, difficulty speaking or a seizure straight away; stay near the treatment centre for at least 2 weeks and do not drive during that time [21]. With bispecific antibodies: fever and chills are common in the days after the first injections and must be reported straight away [17, 18]. If you have severe breathlessness, a seizure or severe confusion, call your local emergency number.
Frequently asked questions
Can diffuse large B-cell lymphoma be cured?
How many cycles of R-CHOP are there and how long does it take?
Usually 6 cycles, one every 3 weeks; that is about 4 months. In limited, low-risk disease, 4 cycles are enough [1]. Each cycle is one day of infusions and 5 days of prednisone tablets [5]. See: The R-CHOP regimen
Is Pola-R-CHP better than R-CHOP?
What is CAR-T and who is it for?
CAR-T is a treatment that turns the patient's own immune cells into "hunters" of lymphoma cells in a laboratory [20]. Today it is mostly for people whose disease came back less than a year after the first treatment or did not respond to it [1, 12, 14], and for later relapses if they have not had CAR-T before [1, 19]. Its important side effects are fever and low blood pressure (called "cytokine release syndrome") and effects on the nervous system, which are managed in specialist centres [21].
Is a bone marrow transplant still needed?
Yes, for a relapse that happens more than a year later and responds to more chemotherapy [1]. In this transplant, the patient's own stem cells are collected and given back after high-dose chemotherapy [9]. See: Blood stem cell transplant and The stages of a transplant
If I am older, will I still get full treatment?
