What is the first treatment for diffuse large B-cell lymphoma?

Diffuse large B-cell lymphoma is a fast-growing lymphoma, so treatment planning usually moves promptly after the diagnosis and staging work-up. Combination chemotherapy is given in cycles, often with an antibody that recognises a marker on the lymphoma cells. The exact medicines and schedule depend on age, organ function, stage, symptoms, and previous treatment. The team may also assess the nervous system or other sites when the disease pattern makes that relevant. CAR T-cell therapy uses a person’s modified immune cells and is generally discussed for selected cases after earlier treatment has failed or the lymphoma has returned.

Before treatment begins, ask about infection prevention, fertility, vaccinations, medicines, and a plan for managing nausea or other side effects. Tell the team about fever, recent infections, heart or kidney problems, and all prescription or non-prescription medicines. Keep appointments for blood tests because they help the team decide whether treatment can proceed safely. Read about Chemotherapy and CAR T-Cell Therapy as preparation for your consultation.

During treatment, call the oncology service urgently for fever, chills, breathlessness, unusual bleeding, severe diarrhoea, confusion, or an inability to drink. Do not wait for the next appointment if you feel suddenly or seriously unwell, because infection and treatment reactions can worsen quickly.

Which chemotherapy and antibody combination is planned, and why? How many treatment visits are expected? What symptoms mean I should call immediately? If treatment does not work or the lymphoma returns, when would CAR T-cell therapy be discussed?
