Chimeric antigen receptor T-cell (CAR T-cell) therapy is available in the Netherlands as a third-line treatment option in patients with large B-cell lymphoma. Bridging is often required during the waiting period between leukapheresis and CAR T-cell infusion. Radiotherapy is an increasingly applied bridging strategy, which is well tolerated by patients and also safe and effective. The most commonly used radiation schedule is 20 Gy in five fractions. In addition to bridging, radiotherapy can also be used as consolidation or salvage treatment after CAR T-cell therapy. Involving a radiation oncologist in a timely manner for patients who are going to be treated with CAR T-cell therapy is of benefit.
